Introduction: Obstructive sleep apnea syndrome (OSAS) is caused by anatomical and non-anatomical factors which lead to upper airway (UA) obstruction during sleep. Intrinsic UA collapse is the most frequent determinant of OSA. In the era of personalized medicine, adopting a tailored diagnostic approach is essential to rule out secondary causes of UA collapse, particularly those stemming from extrinsic anatomical factors. Although being rarely considered in the differential diagnosis, space-occupying lesions of deep cervical spaces such as the parapharyngeal space (PPS) may be responsible for airway obstruction and lead to OSAS. Objective: This study aimed to present an atypical case of OSAS caused by extrinsic PPS compression, outlining the relevance of modern personalized medicine in the diagnostic and therapeutic protocols, and to enhance understanding through a comprehensive literature review. Methods: A 60-year-old female presented with sleep-disordered complaints and was diagnosed with severe OSAS after polysomnography. At physical examination, a swelling of the right posterior oropharyngeal mucosa was noticed. Imaging confirmed the suspicion of a PPS tumor, and transcervical resection was planned. Case presentation was adherent to the CARE checklist. A comprehensive literature review was conducted using the most reliable scientific databases. Results: Surgery was uneventful, and the patient made a full recovery. The histopathology report was consistent with the diagnosis of pleomorphic adenoma. Postoperative outcomes showed marked improvement in polysomnographic parameters and symptom burden. Conclusions: Parapharyngeal space tumors are a rare, often overlooked cause of OSA. This case highlights the role of a personalized head and neck assessment in OSA patients, particularly in identifying structural causes and offering definitive surgical management when indicated.

Background: Limited access to the comprehensive assessment of disorders of the upper aerodigestive tract is a barrier to care in rural health facilities. Assessment of the full aerodigestive tract requires a variety of specialists. The inability to access the necessary specialists can result in misdiagnosis, underdiagnosis, and increased associated mortality. Currently, no single differential diagnostic exam comprehensively assesses all functions of the upper aerodigestive tract to bridge this gap. The purpose of this study is to investigate the feasibility and safety of a novel procedure called ADS that can bridge this gap. Methods: Results from 18,464 ADS procedures were retrospectively analyzed for feasibility, safety and comfort. Results: 96.8% of ADS procedures were successfully completed without complication, confirming the efficacy of the procedure. Conclusions: ADS is a single procedure for the assessment of physiological functions of the upper aerodigestive tract, including swallow, voice, respiration, and cough while also screening for impaired gastric retention and obstructive sleep apnea, which may pose additional urgent and emergent airway threats. ADS may improve health outcomes in underserved populations, e.g., those in a rural community, referred to by other health professionals due to complaints of aerodigestive symptoms and signs.

Background: Voice and swallowing problems are frequently associated with thyroidectomy. Intermittent nerve monitoring (i-IONM) seems to provide a positive effect in reducing its prevalence. The aim of this study was to test the hypothesis that continuous intraoperative nerve monitoring (c-IONM) may reduce the prevalence of these disorders even further than i-IONM. Methods: This 3-arm prospective bi-institutional study compared 179 consecutive patients that underwent thyroidectomy: 56 without IONM, 55 with i-IONM and 67 with c-IONM. Neck dissections and laryngeal nerve palsies were excluded. Two questionnaires (VHI-10 for voice disorders and EAT-10 for swallowing disorders; both validated for Italian language use) were administered before and 1 month after surgery. Statistical significance was analyzed by the chi-squared test. Results: After thyroidectomy, no statistically significant differences were found in the three groups concerning EAT-10. although these symptoms seemed to be influenced by gastro-esophageal reflux. VHI-10 worsened in the “no-IONM” group compared with both i-IONM (p < 0.09, not quite statistically significant) and c-IONM (p < 0.04). Conclusion: Both i- and c-IONM improve voice quality independently of laryngeal nerve integrity. Reduced dissection and particularly restrained manipulation could explain these results, being particularly favorable for c-IONM. Full article

Background: Laryngopharyngeal reflux (LPR) is a common inflammatory condition of the upper aerodigestive tract tissues related to the effects of gastroduodenal content reflux, characterized by a wide variety of clinical manifestations. The aim of our study was to evaluate the possible association between dental disorders and LRP, focusing on the role of salivary changes. Methods: Patient’s dental status was evaluated according to Schiff Index Sensitivity Scale (SISS), Basic Erosive Wear Examination (BEWE) and Decayed, Missing, and Filled Teeth (DMFT) scores. Reflux-associated symptoms were assessed according to Reflux symptom index (RSI). A qualitative and quantitative examination of saliva was performed. Results: Patients suffering from LPR had a higher incidence of dental disorders, regardless the presence of salivary pepsin, and thus, statistically significant higher scores of RSI (p = 0.0001), SISS (p = 0.001), BEWE (p < 0.001) and VAS (p < 0.001). Moreover, they had lower salivary flow compared with healthy patients. Conclusions: The finding of demineralization and dental caries on intraoral evaluation must raise the suspicion of LRP. Reflux treatments should also be aimed at correcting salivary alterations, in order to preserve the buffering capacity and salivary pH, thus preventing mucosal and dental damage. Full article

Background. Cervical trauma can be closed or open, have different degrees of severity, incidence rates, prevalence, or mortality, with variations in the presence of demographic factors. The different types of traumatic injuries have a certain pattern of occurrence depending on criteria related to sex, age, alcohol consumption, and socio-demographic factors. Increasing the rate of trauma is becoming a public health problem and it is necessary to study their epidemiology and implement control strategies. Aims. The objectives of the study are to establish the particularities of epidemiological, morphopathological, and pathophysiological factors involved in complex neck traumatology. Methods. The study group consisted of 384 patients, representative for the population of Moldova, who presented at the ENT Clinic, Hospital “St. Spiridon” Iași and the Institute of Forensic Medicine, Iași during 2012–2016, with complex cervical trauma pathology, produced by various mechanisms, such as car accidents, domestic accidents, aggressions, ballistic trauma, self-inflicted attempts, hanging or strangulation. Data were collected from autopsy reports and medical records. Results. Complex cervical trauma occurs with a predisposition in males, with an average age of 43 years, from rural areas. The mechanism of cervical trauma is predominantly self-inflicted—hanging in 78.4% of the total number of cases, followed by 14.8% of stabbing aggression. The majority of neck injuries, both open and closed, are located in anatomical zone II (73.6%), vascular and pharyngeal are produced by stabbing. Psychiatric disorders and blood alcohol levels are correlated with complex cervical trauma caused by self-inflicted mechanism—hanging and can be considered a predictive factor of suicide attempts. Conclusions. Overall, the vast majority of closed neck injuries were caused by the self-inflicted mechanism, attempted suicide by hanging, followed by the accidental mechanism. Regarding the penetrating complex aero-digestive cervical traumas, they were mostly produced by stabbing both in aggression and self-inflicted circumstances. Aggravating addictive factors such as alcoholism and mental disorders require a competent assessment in terms of the indication of institutionalized treatment, prevention of repeated self-inflicted attempts, or social reintegration.

We share our experience on the implementation of a multidisciplinary aerodigestive program comprising an aerodigestive team (ADT) so as to evaluate its feasibility. We performed a retrospective chart review of the patients discussed at the monthly ADT meetings and analyzed the data. A total of 98 children were referred to the ADT during the study period. The number of cases increased steadily from 3.5 cases per month in 2019 to 8.5 cases per month in 2020. The median age of patients was 34.5 months, and 55% were male. Among the chronic comorbidities, neurologic disease was the most common (85%), followed by respiratory (36%) and cardiac (13%) disorders. The common reasons for consultation were suspected aspiration (56%), respiratory difficulty (44%), drooling/stertor (30%), regurgitation/vomiting (18%), and feeding/swallowing difficulty (17%). Following discussions, 58 patients received active interventions, including fundoplication, gastrostomy, laryngomicrosurgery, tracheostomy, and primary dilatation of the airway. According to the questionnaire of the caregiver, the majority agreed that the main symptoms and quality of life of patients had improved (88%), reducing the burden on caregivers (77%). Aerodigestive programs may provide comprehensive and multidisciplinary management for children with complex airway and digestive tract disorders. Full article

Background: Laryngopharyngeal reflux (LPR) is a common disease in otolaryngology characterized by an inflammatory reaction of the mucosa of the upper aerodigestive tract caused by digestive refluxate enzymes. LPR has been identified as the etiological or favoring factor of laryngeal, oral, sinonasal, or otological diseases. In this case series, we reported the atypical clinical presentation of LPR in patients presenting in our clinic with reflux. Methods: A retrospective medical chart review of 351 patients with LPR treated in the European Reflux Clinic in Brussels, Poitiers and Paris was performed. In order to be included, patients had to report an atypical clinical presentation of LPR, consisting of symptoms or findings that are not described in the reflux symptom score and reflux sign assessment. The LPR diagnosis was confirmed with a 24 h hypopharyngeal-esophageal impedance pH study, and patients were treated with a combination of diet, proton pump inhibitors, and alginates. The atypical symptoms or findings had to be resolved from pre- to posttreatment. Results: From 2017 to 2021, 21 patients with atypical LPR were treated in our center. The clinical presentation consisted of recurrent aphthosis or burning mouth (N = 9), recurrent burps and abdominal disorders (N = 2), posterior nasal obstruction (N = 2), recurrent acute suppurative otitis media (N = 2), severe vocal fold dysplasia (N = 2), and recurrent acute rhinopharyngitis (N = 1), tearing (N = 1), aspirations (N = 1), or tracheobronchitis (N = 1). Abnormal upper aerodigestive tract reflux events were identified in all of these patients. Atypical clinical findings resolved and did not recur after an adequate antireflux treatment. Conclusion: LPR may present with various clinical presentations, including mouth, eye, tracheobronchial, nasal, or laryngeal findings, which may all regress with adequate treatment. Future studies are needed to better specify the relationship between LPR and these atypical findings through analyses identifying gastroduodenal enzymes in the inflamed tissue. Full article

Background: Recurrent respiratory papillomatosis (RRP) is a rare disorder characterized by the generation of papillomas of the aerodigestive tract, usually associated with human papilloma virus (HPV) subtypes 6, 11. INO-3106 is a DNA plasmid-based immunotherapy targeting E6 and E7 proteins of HPV6, in order to create a robust immune T cell response. Methods: Testing of INO-3016 in animal models confirmed immunogenicity of the DNA-based therapy. A single-site open-label Phase 1 study was initiated for patients with HPV6-positive RRP. Patients were dosed with INO-3106 with or without INO-9012, a DNA plasmid immunotherapy that encodes IL-12, delivered intramuscularly (IM) in combination with electroporation (EP) with the CELLECTRA^® device. Patients received an escalating dose of INO-3106, 3 mg once and then 6 mg for three additional doses, each dose three weeks apart, with the third and fourth doses co-administered with INO-9012. The primary objective of the study was to evaluate the safety and tolerability of INO-3106 with and without INO-9012. The secondary objective was to determine cellular immune responses to INO-3106 with and without INO-9012. Exploratory objectives included preliminary clinical efficacy to the therapy. Results: Three patients were enrolled in this study, of which two had RRP. Study therapy was well-tolerated, with no related serious adverse events and all related adverse events (AEs) were low-grade. Injection site pain was the most common related AE reported. Immunogenicity was evidenced by multiple immune assays showing engagement and expansion of an HPV6-specific cellular response, including cytotoxic T cells. Preliminary efficacy was demonstrated in patients with RRP in the form of reduction in need for surgical intervention for papilloma growth. Prior to intervention, both patients required surgical intervention approximately every 180 days. One patient demonstrated a greater than three-fold increase in surgery avoidance (584 days) and the other patient remains completely surgery-free as of the last contact at 915 days, a greater than 5-fold increase in surgery interval. Conclusion: INO-3106 with and without INO-9012 was well tolerated, immunogenic and demonstrated preliminary efficacy in patients with HPV6-associated RRP aerodigestive lesions. Further clinical study is indicated. Full article
