Endoscopic treatment of paediatric subglottic stenosis and cyst (with video)

Introduction. Subglottic stenosis is one of the most common causes of upper airway obstruction. The incidence of post-intubation stenosis ranges from 0.9% to 3% (Rodríguez H. et al.), or from 0.2% to 20% (Haranal M.Y. et al.). Currently, there is no consensus on the choice of surgical tactics due to a large number of modalities for surgical restoration of the laryngeal lumen.Material and methods. 44 patients with postintubation laryngeal stenosis were treated in the surgical thoracic department of the National Medical Research Center of Children’s Health subordinate to the Ministry of Health of the Russian Federation during 2019-2021. The average age of patients in this group was 4 years 8 months ± 3 years 8 months. Endoscopic treatment was done to 24 patients (54.5%). Laryngoscopy, fibrobronchoscopy, multispiral computed tomography and, if necessary, barium esophagogram were done for additional diagnostics.Results. The average number of endoscopic procedures per patient was 2.9 ± 1.5 (range from 1 to 7). Good results were seen in 20 patients (83.3%).Conclusions. Endoscopic techniques are alternative options to open reconstructive surgery. These techniques give good results in treating stenoses in the subglottic space and give a good chance to avoid tracheostomy in a certain group of patients, which, according to the results of our study, was as large as 79.1%.

Laryngotracheal Resection

Idiopathic subglottic stenosis (ISS) is a rare inflammatory process of unknown cause, usually limited to the subglottic region and the first 2 tracheal rings. We performed a retrospective analysis of our experience with a series of patients with this condition. The study involved retrospective review of the records of patients with ISS. A series of criteria that included patient clinical history, laboratory tests, flexible nasolaryngoscopic examination, and biopsies were used to establish a diagnosis. Symptoms, treatment, and outcome were examined. A total of 16 patients were identified; 14 were female (87.5%), and 2 were male. The mean follow-up time was 75.5 months. Fourteen patients required surgical treatment for respiratory compromise. Nine of these cases have been controlled effectively with endoscopic laser techniques. Endoscopic management failed in 5 patients, and 2 patients underwent laryngotracheal resection and reconstruction. Mitomycin-C was used in 6 patients as an adjuvant to endoscopic laser surgery. Patients in whom endoscopic treatment failed were noted to have thicker (>1 cm) and more complex stenoses. The diagnosis of ISS is a diagnosis of exclusion. A complete workup of the patient must be performed to rule out other causes of stenosis. Endoscopic laser surgery is a valid initial approach for thinner, noncomplicated lesions. Patients with thicker, complex lesions in whom endoscopic treatment fails are best managed with laryngotracheal resection and reconstruction. However, adjuvant use of mitomycin-C may prove beneficial in the treatment of these patients. Estrogen may play a role in the pathogenesis of ISS by altering the wound healing response.
