Purpose The purpose of this work was to determine the epidemiology and the predictive factors of success of the surgical management of fourth branchial anomalies. Methods This is a multicentric retrospective review from 1998 to 2016 of patients who presented with an endoscopically-confirmed fourth branchial pouch anomaly. Data were analyzed according to sex, age, clinical features, number of recurrences, treatment modalities (endoscopic and/or cervicotomy), post-operative complications and follow-up. Results Fifty-two children have been included. The average age at diagnosis was 4.5 years. Among them, 73.1% were female, 11.4% were neonatal forms; 94.2% of lesions were left-sided; 75% of patients presented a cervical abscess as first symptom, and 7.7% of children presented with dyspnea. Average time between first symptoms and management was 9.5 months. Management was endoscopic in 73.1% of patients (laser in 84.2%, coagulation in 15.8%) with about a third of recurrence after one procedure. Overall success of endoscopic procedures reached 84.2%. A cervical open surgery was performed in 26.9% as first line treatment. Overall success of cervicotomy reached 85.7%. No complications of endoscopic surgery have been identified. There were 35.7% complications of cervicotomy (2 recurrent nerve palsy, 2 keloid scars, 1 pharyngostoma). An association was proved between recurrences and initial abscess (OR = 2.44), and with age between 3 and 5 (OR = 4). Conclusion Endoscopic treatments appear to be effective in first line approach in the management of fourth branchial anomalies, offering an excellent efficiency with rare complications. We identified two risk factors of recurrence: age between 3 and 5 years old and history of cervical abscesses. Level of evidence IV.

Introduction Suprastomal Collapse (SuStCo) is a common complication of prolonged tracheostomy in children. There is a paucity of literature on this subject, especially regarding how to manage significant suprastomal collapse that prevents safe decannulation. Objective Provide a definition, classification system, and recommend management options for significant suprastomal collapse in children with tracheostomy. Methods Members of the International Pediatric Otolaryngology Group (IPOG) who are experts in pediatric airway conditions were surveyed and results were refined using a modified Delphi method. Results Consensus was defined as > 70% agreement on a subject. The experts achieved consensus: • on a standard definition of Suprastomal Collapse • that there is clinical importance between significant and insignificant collapse • that the gold standard diagnostic modality is endoscopic examination under anesthesia • that the severity of collapse is a major determinant in the surgical approach • that surgical intervention is the first line management in combined anterior and lateral Suprastomal Collapse. Conclusion This consensus statement provides recommendations for medical specialists who manage infants and children with tracheostomies with significant Suprastomal Collapse. It provides a classification system to facilitate diagnosis and treatment options for this condition.

Objectives The purpose of this work was to assess epidemiological aspects, surgical approach, morbidity and mortality rates of patients presenting with tracheal stenosis requiring surgery, and the evolution of surgical techniques over the last years. Methods We performed a retrospective observational study from 1990 to 2017 in a pediatric tertiary-care center with needing surgery for tracheal stenosis. We analyzed clinical patients' characteristics, type of stenosis, type of surgery and follow-up. Results Twenty-eight children presented with tracheal stenosis, half of them with congenital stenosis (complete tracheal rings) and the other half with acquired stenosis (neoplasic or post intubation injury). 39.3% of these stenoses were associated with a vascular ring (61.5% in case of congenital stenosis). Depending on the extent of the stenosis and its origin, the surgery could be performed endoscopically or by an external approach. Enlargement tracheoplasty with an autograft (14.3%) was replaced by slide tracheoplasty with Cardio Pulmonary By-Pass (CPBP, 28.6%) with improved results for the treatment of long segment tracheal stenosis, involving more than 30% of the tracheal length (all were congenital in our study). Slide tracheoplasty has been performed since the late 90's in our institution. 25% of children have had a resection and anastomosis of the trachea because they had a stenosis involving less than 30% of tracheal length. Endoscopic surgery was performed for membranous stenoses, which were often seen after intubation or tracheotomy (32.1% of patients). Conclusion Effective treatment of surgical tracheal stenosis was performed in 28 children between 1990 and 2015. Surgical techniques have evolved over time, leading to a better management of this rare and serious disease.

To analyze prognostic factors in the management of patients with choanal atresia.This is a review of 114 patients operated on for choanal atresia in a tertiary care center between November 1986 and November 2016, including clinical characteristics, surgical management, and postoperative course with final nasal patency. The data were collected in a database that was updated over time.Among the 114 patients, 78 were female, 77 presented with unilateral choanal atresia, and 37 presented with bilateral unilateral choanal atresia, corresponding to 151 nasal fossae. Forty-seven patients had associated abnormalities (41.2%), including CHARGE, diagnosed in 20 children (17.5%). At the end of follow-up, 91 patients (79.8%) had normal choanal patency. The identified risk factors of surgical failure were age6 months (P = .004), weight5 kg (P = .007), and bilateral choanal atresia (P .001). The type of atresia, presence of associated abnormalities, surgical approach, stenting, and use of mitomycin were not significantly linked with the surgical results.This series highlights the importance of the timing of surgery, which is guided by the clinical ability of the infant to tolerate the procedure. Endoscopic approaches are widely performed, but a transpalatal approach, necessary in some cases of bilateral choanal atresia, does not alter the results. Unilateral choanal atresia surgery should be delayed after age 6 months and/or weight5 kg when possible.
