Introduction: Tracheotomy as a surgical procedure has existed and evolved since ancient times. In modern medicine, surgical techniques for performing this procedure in adults and children have reached a high level of perfection. However, pediatric tracheotomy remains a challenging surgical intervention, performed in only a limited number of centers by a small number of surgeons. This is due to several unresolved issues related to the procedure—such as indications, timing, decannulation protocols, and the care of tracheotomized children—which are still usually left to the individual judgment of the physician. Additionally, there is a significant psychological barrier associated with performing tracheostomy in a child (particularly in those under the age of one). Aim: This article aims to present in detail the modern surgical approach to performing tracheotomy in pediatric patients, examine the different types of tracheotomy, and highlight its specific features related to the anatomical differences between children and adults. Discussion: After the decision to perform a tracheotomy is made, the exact surgical technique and type of tracheostomy to be created are selected alongside the patient’s preoperative preparation. Factors such as the child’s age, the surgeon’s experience, and the underlying disease for tracheotomy play crucial roles in determining the appropriate approach. Conclusions: Pediatric tracheotomy has undergone significant development over the years. Nowadays, the exact type of surgical intervention depends on the individual needs of young patients.

Odontogenic cysts are frequently encountered in clinical practice. However, residual cysts, a specific type of inflammatory odontogenic cyst, are relatively rare. These cysts may slowly expand over time, damaging surrounding soft tissues and bone, typically without posing a threat to life. We report the case of a 67-year-old man with liver failure and a cystic tumor in his right maxilla that had invaded his oral cavity and cheek, causing nasal obstruction and severe bleeding following an incisional biopsy. A computed tomography (CT) scan of the mass was nonspecific, and an initial histopathological analysis of the tissues was inconclusive due to chronic inflammation and hemorrhagic alterations, complicating the diagnostic pathway. The suspicion of a potentially aggressive malignant neoplasm and the need for immediate intervention due to bleeding necessitated a tracheotomy, tumor removal, percutaneous endoscopic gastrostomy, and transfusions of red blood cells. A subsequent histopathological examination revealed features indicative of a residual cyst. The entire lesion was excised through functional endoscopic sinus surgery. The surgical treatment was performed safely and effectively. Follow-up CT confirmed complete removal of the lesion. This case highlights a rare yet possible complication of odontogenic cysts and underscores the necessity of early diagnosis and comprehensive prophylaxis to prevent severe complications.

Introduction: Benign subglottic/tracheal stenosis (SG/TS) is a life-threatening condition commonly caused by prolonged endotracheal intubation or tracheostomy. Invasive mechanical ventilation was frequently used to manage severe COVID-19, resulting in an increased number of patients with various degrees of residual stenosis following respiratory weaning. The aim of this study was to compare demographics, radiological characteristics, and surgical outcomes between COVID-19 and non-COVID patients treated for tracheal stenosis and investigate the potential differences between the groups. Materials and methods: We retrospectively retrieved electronical medical records of patients managed at two referral centers for airways diseases (IRCCS Humanitas Research Hospital and Avicenne Hospital) with tracheal stenosis between March 2020 and May 2022 and grouped according to SAR-CoV-2 infection status. All patients underwent a radiological and endoscopic evaluation followed by multidisciplinary team consultation. Follow-up was performed through quarterly outpatient consultation. Clinical findings and outcomes were analyzed by using SPPS software. A significance level of 5% (p < 0.05) was adopted for comparisons. Results: A total of 59 patients with a mean age of 56.4 (±13.4) years were surgically managed. Tracheal stenosis was COVID related in 36 (61%) patients. Obesity was frequent in the COVID-19 group (29.7 ± 5.4 vs. 26.9 ± 3, p = 0.043) while no difference was found regarding age, sex, number, and types of comorbidities between the two groups. In the COVID-19 group, orotracheal intubation lasted longer (17.7 ± 14.5 vs. 9.7 ± 5.8 days, p = 0.001), tracheotomy (80%, p = 0.003) as well as re-tracheotomy (6% of cases, p = 0.025) were more frequent and tracheotomy maintenance was longer (21.5 ± 11.9 days, p = 0.006) when compared to the non-COVID group. COVID-19 stenosis was located more distal from vocal folds (3.0 ± 1.86 vs. 1.8 ± 2.03 cm) yet without evidence of a difference (p = 0.07). The number of tracheal rings involved was lower in the non-COVID group (1.7 ± 1 vs. 2.6 ± 0.8 p = 0.001) and stenosis were more frequently managed by rigid bronchoscopy (74% vs. 47%, p = 0.04) when compared to the COVID-19 group. Finally, no difference in recurrence rate was detected between the groups (35% vs. 15%, p = 0.18). Conclusions: Obesity, a longer time of intubation, tracheostomy, re-tracheostomy, and longer decannulation time occurred more frequently in COVID-related tracheal stenosis. These events may explain the higher number of tracheal rings involved, although we cannot exclude the direct role of SARS-CoV-2 infection in the genesis of tracheal stenosis. Further studies with in vitro/in vivo models will be helpful to better understand the role of inflammatory status caused by SARS-CoV-2 in upper airways. Full article

We aimed to describe the prevalence, risk factors, morbidity and mortality associated with the occurrence of bacteraemia during the postoperative ICU stay after lung transplantation (LT). We conducted a retrospective single-centre study that included all consecutive patients who underwent LT between January 2015 and October 2021. We analysed all the blood cultures drawn during the postoperative ICU stay, as well as samples from suspected infectious sources in case of bacteraemia. Forty-six bacteria were isolated from 45 bacteraemic patients in 33/303 (10.9%) patients during the postoperative ICU stay. Staphylococcus aureus (17.8%) was the most frequent bacteria, followed by Pseudomonas aeruginosa (15.6%) and Enterococcus faecium (15.6%). Multidrug-resistant bacteria accounted for 8/46 (17.8%) of the isolates. The most common source of bacteraemia was pneumonia (38.3%). No pre- or intraoperative risk factor for bacteraemia was identified. Recipients who experienced bacteraemia required more renal replacement therapy, invasive mechanical ventilation, norepinephrine support, tracheotomy and more days of hospitalization during the ICU stay. After adjustment for age, sex, type of LT procedure and the need for intraoperative ECMO, the occurrence of bacteraemia was associated with a higher mortality rate in the ICU (aOR = 3.55, 95% CI [1.56–8.08], p = 0.003). Bacteraemia is a major source of concern for lung transplant recipients. Full article

(1) Background: Deep hypothermic circulatory arrest (DHCA) with selective antegrade cerebral perfusion (ACP) is an established cerebral protection technique for the conduction of complex surgical procedures involving the aortic arch. It is controversial whether the duration of DHCA is associated with adverse outcome in patients with acute type A aortic dissection (AAAD). Our goal was to investigate whether DHCA time was associated with surgical outcome in patients undergoing a surgical treatment of AAAD. (2) Methods: A total of 410 patients were divided into two groups based on the DHCA time less than 60 min and equal to or longer than 60 min. (3) Results: Patients with longer DHCA times were significantly younger (p = 0.001). Intraoperatively, complex procedures with aortic arch surgery were more common in patients with longer DHCA times (p < 0.001). Accordingly, cardiopulmonary bypass (p < 0.001), cross-clamping (p < 0.001) and DHCA times (p < 0.001) were significantly longer in this group. Postoperatively, only the duration of mechanical ventilation (p < 0.001) and the rate of tracheotomy were significantly higher in these patients. Thirty-day mortality was satisfactory for both groups (p = 0.746). (4) Conclusions: Our results showed that improvements in perioperative management including ACP allow for the successful performance of surgical treatment of AAAD under DHCA with a duration of even longer than 60 min.
