Background/Objectives: Hearing loss is a disorder that develops because of being exposed to high noise levels affecting the quality of life among affected individuals. A review of the literature was conducted to explore the prevalence of hearing loss and its associated factors among workers in the metal industry. Methods: The literature search was conducted on ScienceDirect, Google Scholar, Pub Med, ResearchGate and African Journals Online databases to identify articles according to the Preferred Reporting Items for Systematic Reviews and Meta analyses (PRISMA) guidelines. The studies published in scientific journals between January 2014 and December 2024 describing hearing loss and its associated factors among workers in the metal industry were considered for inclusion in the review. The articles were screened by the author. The Critical Appraisal Skills Programme (CASP) quality assessment tool with modified checklist questions was used to evaluate the quality of studies. Results: Following the literature search and using the relevant inclusion criteria, a total of 127 articles were identified, and 8 articles with a total of 2605 participants were included in the review. The sample sizes ranged from 93 to 606. The participants’ age ranged from 19 to 65 years. A review of studies showed varying prevalence of hearing loss ranging from 13.8% to 59%. Furthermore, the studies have found working experience, advanced age, cigarette smoking, tinnitus, working in areas of high noise levels and not using hearing protective devices to be associated with a risk of developing hearing loss. Conclusions: The review found that workers in the metal industry are at risk of developing hearing loss and, therefore, implementation of control measures to prevent the occurrence of hearing loss is necessary.

Background/Objectives: Maxillofacial volumetric deficits are often treated using structural fat grafting with autologous free fat grafts. The buccal fat pad (BFP) is commonly used as a pedicled flap for limited oral cavity applications. This study explores its use as a free graft for reconstructing deformities in the upper and lower lips caused by trauma or tumor resections. Methods: Five patients underwent soft tissue defect reconstruction using a free fat graft from the BFP, following standard surgical procedures. Techniques for harvesting, transferring, and evaluating aesthetic and functional outcomes up to three months post-surgery are detailed, with long-term follow-up extending to an average of 20 months (range 12–24 months). Results: Initial post-operative assessments showed lip asymmetry due to edema and excessive graft volume. Partial necrosis was observed within 1–2 weeks, typical of tissue healing. By 4–5 weeks, mucosal revascularization occurred, with desired lip volume and functionality achieved between 8–12 weeks. Long-term follow-up averaging 20 months demonstrated excellent graft stability with no volume regression beyond the vermilion border in all patients. Conclusions: The BFP as a free graft offers advantages such as high survival rates and easy harvesting. It effectively restores lip function, volume, and aesthetics. Challenges include graft manipulation, retention, potential fibrosis, and volume unpredictability. Future refinements in technique and follow-up are necessary to overcome these issues, enhancing the reliability of BFP for lip reconstruction. Full article

Background/Objectives: Conductive hearing loss (CHL) recurrence or persistence after stapes surgery is often due to prosthesis displacement or malfunction, with malleus fixation being a less common cause. While persistent CHL linked to malleus fixation can be managed with appropriate diagnosis and surgical intervention, recurrent CHL cases remain poorly documented. This report describes a rare case of recurrent CHL due to malleus neck fixation, likely secondary to surgical trauma. Case Presentation: A 49-year-old woman underwent bilateral stapedectomy. CHL worsened after two years. CT showed right incus erosion and a left bony bridge. Revision surgery corrected the right side. Left tympanotomy revealed malleus fixation from a prior atticotomy. Removing the bony bridge restored ossicular mobility and hearing, stable at 6 and 12 months. Discussion: Malleus fixation after stapedectomy is rare and often related to congenital anomalies, chronic otitis media, tympanosclerosis, or surgical trauma. Bone dust or fragments from surgery may promote new bone formation, causing delayed fixation. Ossicular fixation can develop postoperatively and may be missed during primary surgery. High-resolution CT aids in diagnosis, especially in revision cases, while intraoperative palpation is key to detecting subtle abnormalities. Treatment options include ossicular mobilization, prosthesis revision, or chain reconstruction, tailored to the fixation’s location and severity. Conclusions: Surgical trauma should be considered a potential cause of recurrent CHL post-stapedectomy. Thorough removal of bone debris through aspiration and irrigation during surgery is essential to minimize this risk and optimize long-term hearing outcomes. Full article

Background: The posterior labyrinth is particularly vulnerable to ischemic injury. Vertigo can occasionally be the only presenting symptom of acute myocardial infarction (AMI). Acute Bilateral Vestibular Neuropathy (ABVN) is an extremely rare condition, with only three cases previously reported in the literature. Its exact pathophysiological mechanisms remain unclear. Case Presentation: We present the case of a 76-year-old male who presented to the emergency department (ED) with vertigo and severe postural unsteadiness. Subsequently, a silent AMI was diagnosed, prompting cardiac stenting. Vestibular function assessments over the following eight months confirmed the diagnosis of ABVN. A cycle of vestibular rehabilitation yielded limited objective benefit, although the patient reported subjective improvement as measured by the Dizziness Handicap Inventory (DHI). Discussion and Conclusions: This case suggests a potential association between peripheral vestibular dysfunction and acute hemodynamic impairment due to myocardial infarction. Notably, it represents the first reported case of ABVN following a silent AMI, presenting solely with vestibular symptoms. Full article

The aim of this study article is to better understand patient outcomes following simple nasal fracture realignment, comparing outcomes when performed under LA versus GA. A systematic search of the evidence base is conducted. Data extraction and documentation are performed in keeping with PRISMA guidance. Critical appraisal tools are applied to aid quality assessment and assessment of bias. Twelve articles were selected for inclusion in this review, accumulating 2405 participants in total. No significant difference in patient outcomes between the LA and GA groups was observed. There was high variation in article quality, with some assessed as having a high risk of bias. Although some methodological limitations and outcome heterogeneity between studies hamper our ability for direct comparison, it seems likely that patient outcomes after nasal fracture correction under LA versus GA are comparable. Further large-scale studies with an agreed set of outcome measures are required to understand this relationship more fully. Full article

Background/Objectives: Leishmania spp. are protozoan parasites transmitted by female sandflies (Phlebotomus or Lutzomyia). Clinical manifestations depend on species and host immunity. While cutaneous and visceral forms prevail, mucocutaneous involvement—particularly isolated nasal septum leishmaniasis—is rare and frequently misdiagnosed as an inflammatory, infectious, or neoplastic condition. Risk factors associated with mucocutaneous leishmaniasis include systemic or local immunodeficiency, prior renal transplantation, treatment with chronic inhaled steroids, residence in endemic areas or travel to such regions, and previous Leishmania infections. Immunosuppressed patients are at higher risk for atypical presentations and delayed diagnosis, which can result in extensive tissue destruction. Early clinical suspicion, histopathological confirmation, and prompt therapy are essential to prevent permanent mucosal damage. Therefore, a multidisciplinary approach is needed for adequate evaluation and effective treatment. Methods: A 67-year-old man with rheumatoid arthritis on methotrexate reported a two-year history of right-sided nasal obstruction and ulceration that failed to respond to antibiotics. He did not present systemic symptoms. Results: Facial CT revealed a septal deviation; the patient underwent septoplasty, and biopsy confirmed Leishmania amastigotes. Serology (rK39 immunochromatographic test) was positive. He was treated with liposomal amphotericin B at 4 mg/kg/day for five days, followed by miltefosine at 100 mg/day orally for 14 days. At an eight-week follow-up, the nasal mucosa was fully healed, obstruction was resolved, and there was no evidence of recurrence. Conclusions: Although nasal septum leishmaniasis is uncommon, it should be considered in the differential diagnosis of chronic nasal lesions, especially in immunocompromised patients or those from endemic regions. Definitive diagnosis requires biopsy with histological or molecular confirmation. Combined liposomal amphotericin B and miltefosine therapy yields high cure rates and prevents mucosal destruction. Early recognition is critical to avoid diagnostic delays and long-term sequelae. Full article

Chronic rhinosinusitis (CRS) is a prevalent inflammatory condition of the nasal and paranasal mucosa that significantly impacts the quality of life. Postoperative inflammation and polyp recurrence remain common despite advances in endoscopic sinus surgery (ESS), prompting interest in localized corticosteroid delivery systems. This review analyzes bioresorbable steroid-releasing implants and corticosteroid-impregnated nasal dressings, focusing on their pharmacologic mechanisms, safety, and clinical outcomes. A synthesis of findings from randomized trials and observational studies was performed, with emphasis on devices such as Propel™, NasoPore, Merocel, SinuBand FP, and gel-based dressings. The Propel implant demonstrated robust evidence for reducing adhesions and inflammation with negligible systemic absorption. NasoPore and Merocel provided structural support and localized steroid delivery but lacked controlled-release kinetics. Gel-based dressings and SinuBand FP offered anatomic adaptability, with limited systemic effects. Some methods showed systemic steroid exposure in cortisol monitoring. Corticosteroid-releasing devices enhance ESS outcomes through localized therapy. While Propel is the most validated, other devices remain viable alternatives in specific clinical contexts. Comprehensive safety monitoring and standardized trials are essential to optimize their integration into postoperative care. Full article

Background: Interdigitating dendritic cell sarcoma (IDCS) is a very rare haematologic malignant tumour that arises from antigen-presenting cells. While it primarily affects the lymph nodes, extranodal manifestations have been observed, and there is a slight male predominance. Due to its rarity, diagnosing IDCS can be challenging, as illustrated in our case report of a 61-year-old woman. Methods: In this case presentation, the oncological management of a patient suspected of having malignant melanoma metastasis in the neck lymph nodes is discussed. This includes otorhinolaryngological examinations, fine needle aspiration biopsy, PET CT imaging, and histological analysis with immunohistochemistry. Results: The patient’s medical history included the excision of a pigmented lesion from the left ala of her nose, which was diagnosed as malignant melanoma. After surgical treatment, she experienced a tumour-free period of one year; however, during a follow-up ultrasonography three pathological lymph nodes were detected on the left side of her neck. Initially, a nodal metastasis of melanoma was suspected. Yet, fine needle aspiration cytology revealed myofibroblastic tumour invasion, and a re-biopsy showed no signs of malignancy. To further investigate, PET-CT scans were conducted, and a modified radical neck dissection was performed based on the findings. The histological analysis of the lymph nodes revealed an IDCS, a second independent tumour distinct from the initially diagnosed malignant melanoma, originating from the submandibular, upper jugular, and mid-jugular lymph nodes. Conclusions: This case highlights the diagnostic difficulties associated with IDCS. Initially, the clinical suspicion of malignant melanoma was considered, necessitating further examinations and a multidisciplinary approach to reach a final diagnosis and provide the patient with appropriate treatment.

Background/Objectives: Hearing aids are essential for managing hearing loss, yet their accessibility, consistent use, and maintenance remain challenging in public healthcare systems, particularly in low- and middle-income countries (LMICs) such as South Africa. Despite the availability of these services, many patients struggle with device utilization, resulting in suboptimal rehabilitation outcomes. This study explores patient experiences with hearing aids in South Africa’s public healthcare sector. This study aimed to (1) assess patients’ experiences with hearing aid access, including waiting times and service delivery; (2) identify challenges related to hearing aid maintenance and repairs in the public sector; (3) explore factors influencing consistent hearing aid use, including social, psychological, and practical barriers; and (4) propose strategies to enhance hearing aid provision and aftercare services in South Africa. Methods: This descriptive qualitative study was conducted at two public healthcare facilities in Johannesburg. Purposive sampling was used to recruit 15 adult hearing aid users who had received government-funded hearing aids within the past 12 months. Semi-structured interviews were conducted, transcribed verbatim, and analyzed using thematic analysis. Results: Participants reported long waiting periods (up to a year) for hearing aids, with poor communication regarding timelines. Challenges included difficulties adjusting to amplification, discomfort, and battery shortages, leading to inconsistent use or device abandonment. Social stigma and lack of family support further discouraged consistent use. Repair services were slow, with waiting times exceeding three months. Participants recommended decentralized battery distribution, structured follow-up appointments, improved aftercare, awareness campaigns, and mobile audiology services to improve accessibility and usability. Conclusions: While public hearing aid provision is essential for hearing rehabilitation, systemic inefficiencies, maintenance issues, and social barriers limit its impact. Strengthening aftercare services, decentralizing hearing aid distribution, and increasing public awareness could significantly improve hearing aid accessibility and adherence. Furthermore, policy interventions that incorporate tele-audiology, community-based maintenance programs, and integrated healthcare approaches are crucial in ensuring sustainable hearing healthcare outcomes.

Background/Objectives: Long-term prosthetic stability in ossicular chain reconstruction (OCR) surgery may be affected by multiple factors, including prosthesis type. We compared audiometric outcomes including air–bone gap (ABG) and air conduction pure-tone average (AC PTA) over a multi-year period in titanium clip partial prosthetics and other titanium partial and total ossicular reconstruction prostheses. Methods: This was a retrospective study of 92 adult patients (19–74 years) receiving primary, second-look, or revision OCR at a single institution between 2017 and 2021. ABG and AC PTA at short (3–6 months) and long-term (>12 months) postoperative follow-up were compared among patients receiving clip partial prosthetics, traditional PORPs, and TORPs. Results: Overall, AC PTA and ABG were significantly improved in the short term and did not significantly deteriorate in the long term. Clip partial prostheses had significantly lower AC PTAs and ABGs than TORPs in both the short and long term and no difference with PORPs. There was also no significant deterioration in audiometric outcomes in either clip partials, PORPs, or TORPs over time. Clip partials had the highest rate of short- and long-term surgical success (i.e., ABG ≤ 20 dB) with 62.2% and 54.1%, respectively. Cholesteatoma and revision status were not independent predictors of long-term ABG success. Conclusions: The clip partial prosthesis seems to demonstrate similar, and potentially increased, resilience compared to the PORP and TORPs in both the short and long term. They may have comparable effects on audiometric outcomes to PORPs, demonstrating postoperative ABG and AC PTAs that reflect the previous literature. Clip partials appear to be a safe and effective prosthetic for OCR in patients with intact stapes regardless of cholesteatoma or revision status. Full article

Background/Objectives: This study focuses on examining treatment outcomes of sinonasal squamous cell carcinoma (SNSCC) when induction chemotherapy is added to definitive treatment regimens. A systematic literature search was conducted in the following four bibliographic databases: Embase, MEDLINE, Web of Science and Cochrane Central Register of Controlled Trials (CENTRAL). A total of 604 patients across 12 studies were included in the final review. Methods: This systematic review adheres to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Pooled survival curves were derived from reconstructed individual patient data using Guyot et al.’s methodology, in which K-M curve drops are measured relative to the numbers-at-risk and number of events. Results: In this study, 71% of patients were male and 93% presented with late-stage (T3–4) cancer. The 24-month and 60-month overall survival rates were 55.1% and 35.0%, respectively. The 24-month disease-free survival was 44.4% and remained relatively stable at 42.1% at 60 months. The local control rate remained stable from 24 to 60 months at 72.7%. Conclusions: Compared to the results from the existing literature, this review reveals an overall survival and disease-free survival (DFS) that is comparable to that of other multimodality treatment options. The local control rate (LCR) was also high. This review suggests that induction chemotherapy can be utilised for patients with advanced SNSCC. Full article

Background: The nasal septal swell body (NSB) is a thickened area of the nasal septum with erectile tissues, located above the nasal floor. We hypothesized that the presence of the NSB in this space exerts favorable effects to generate laminar nasal airflow by developing its morphology as adjusted to nasal septal deviation (NSD). Patients and Methods: We objectively measured the NSB morphology in 152 patients by computed tomography (CT) and assessed its relationship with the width of the inferior turbinate (IT), the severity of NSD, and the patency of the nasal airflow passage (NAP). Results: In the patients with moderate or severe NSD, the mean widths of the NSB, IT, and NAP were significantly narrower at the convex side compared to the paired concave side, with the degree being more prominent in the severe-NSD group. A positive correlation was observed between the degree of the NSD angles and the difference in the widths of the NSB (r = 0.805) and IT (r = 0.609). Conclusions: These results imply novel roles of the NSB in the maintenance of physiological nasal airflow to generate a laminar airflow from the nostrils toward the middle nasal meatus at a constant rate.

Objectives: Slag injuries in industrial settings pose risks of hearing loss and complications. The aim of this study is to provide specialists with a better understanding of the sequelae, treatment, and long-term outcomes that a patient may have following a slag injury to the tympanic membrane. Data Sources: PubMed, Embase, and Web of Science. Methods: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), multiple databases were queried for articles published from inception to 2023 describing Tympanic membrane injuries from welding. The publications were screened by two independent viewers. The Joanna Briggs Institute 2017 Critical Appraisal Checklist was used to assess the quality of studies. Results: A total of 227 articles were identified, and 9 full-text articles were included in this review, comprising a total of 18 patients. The patients’ ages ranged from 18 to 75 years. Most commonly, patients were welding overhead in a tight working space, and none of the patients were wearing protective ear equipment in addition to their welding masks. Patients experienced otalgia (n = 10; 55%), hearing loss (n = 11; 65%), vertigo (n = 6; 35%), chronic otorrhea (n = 5; 29%), and facial paralysis (n = 4; 23%). A total of 12 patients (70.6%) required surgery, most requiring debridement of metallic foreign body multiple times, some undergoing surgery up to four years post-injury. Conclusions: Tympanic membrane injuries from welding are often overlooked. They cause hearing loss and facial nerve damage. Following a period of observation, sturdy reconstruction with cartilage grafting is recommended, given the poor vasculature and inflammation after this injury. Full article

Background and Clinical Significance: GLI1 gene alterations have recently been identified as a pathological phenomenon associated with a distinct novel entity of mesenchymal neoplasms. They have been reported to occur in any soft tissue of the body, with a specific affinity for the head and neck region. The aim of this article is to increase awareness of this entity and provide a detailed summary of the modes of presentation and diagnostic and therapeutic issues surrounding these tumours occurring in the head and neck region. Case Presentation: We report the case of a 39-year-old male patient with ACTB::GLI1 fusion-related mesenchymal tongue tumour who was successfully treated by surgery. Conclusions: GLI1-altered mesenchymal tumours in the head and neck may harbour various clinical presentations. Larger series are needed to better define the clinicopathological range of this novel entity. We suggest a follow-up period of at least 2 years with imaging, followed by a clinical follow-up of 3 years. Certain clinicopathological features may warrant further and more extensive follow-up.

Background/Objectives: Galvanic vestibular stimulation (GVS) integrated into virtual reality (VR) environments enhances immersion and mitigates cybersickness. It is well known that GVS can affect standing balance. Most studies have investigated the effects of GVS in VR in seated conditions. The purpose of this study was to evaluate the impact of joint GVS and VR with moving visual stimulus on standing balance. Methods: Using a repeated measures counter-balanced design, motion sickness, postural sway, and velocity utilizing the center of pressure (COP) along the mediolateral (ML) and anteroposterior (AP) axes were obtained in 18 subjects during optokinetic (OPK) stimulus (black and white vertical bars moving from left to the right) in VR across three interventions: GVS in the same direction of visual stimulus—left to right ear (Positive GVS), GVS in the opposite direction of visual stimulus—right to left ear (Negative GVS), and without GVS (Null GVS). Motion sickness symptom scoring was obtained using the Pensacola Diagnostic Index. Results: The PDI score was increased significantly in the Negative GVS. The root mean square and sway range of COP along ML was greater during the Positive GVS and Negative GVS than the Null GVS, while, along AP, it was only greater during Negative GVS. During Positive GVS, mean positive and negative peak velocities, only in ML, were increased and decreased, respectively. During Negative GVS, only negative peak velocities in both ML and AP directions were decreased. Conclusions: This research highlights the importance of testing combined VR and GVS to assess standing balance while mitigating cybersickness. Full article

Epistaxis, commonly referred to as nosebleeds, is a frequent clinical presentation with etiologies spanning from localized trauma to systemic conditions and medication effects. Despite its high prevalence, management approaches vary significantly depending on the cause and severity. To provide a comprehensive review of current management strategies for epistaxis, focusing on initial interventions, evaluation techniques, and preventive measures. A structured review of the literature was conducted to identify effective strategies for the initial management, evaluation, and prevention of epistaxis. Emphasis was placed on practical applications for clinicians in both emergency and outpatient settings. Initial Management: Direct pressure and topical vasoconstrictors remain the first-line interventions. Persistent cases may require nasal packing or cautery. Evaluation: Identification of underlying causes such as hypertension, coagulopathies, and structural nasal abnormalities is crucial, particularly in recurrent or severe cases. Laboratory tests and imaging may aid in diagnosis and management planning. Prevention: Patient education on nasal hygiene, avoidance of nasal trauma, and maintenance of a humidified environment are critical in reducing recurrence. Integrating effective initial management with thorough evaluation and preventive strategies significantly improves patient outcomes. Full article
