Multicentric study applying the european laryngological society classification of benign laryngotracheal stenosis in adults treated by tracheal or cricotracheal resection and anastomosis

AbstractObjectiveTo propose a new classification of inner-ear anomalies that is more clinically oriented and surgically relevant: the SMS (Sawai Man Singh) classification of cochleovestibular malformations.MethodsA retrospective multicentric study was conducted of 436 cochlear implantations carried out in 3 Indian tertiary care institutes. Patients with anomalous anatomy were included and classified, as per the new SMS classification, into cochleovestibular malformation types I, II, III and IV, based on cochlear morphology, modiolus and lamina cribrosa.ResultsThere were 19, 23, 8 and 4 patients with cochleovestibular malformation types I, II, III and IV, respectively. Two-year post-operative Meaningful Auditory Integration Scale scores were statistically analysed.ConclusionThis new classification for inner-ear anomalies is a simpler, more practical, outcome-oriented classification that can be used to better plan the surgery. These merits make it a more uniform classification for recording results.

Cricotracheal resection (CTR) is a technique introduced comparatively recently for treating severe laryngotracheal stenosis in children. The recognized complications of CTR include recurrent laryngeal nerve damage, anastomotic dehiscence, and restenosis. We describe a further complication of CTR, namely, prolapse of the arytenoid cartilage. The presentation may be late, with symptoms of shortness of breath on exertion and nocturnal stertor with a poor sleep pattern, or the prolapse may be an asymptomatic incidental finding. The diagnosis is performed with flexible nasopharyngoscopy with the patient unanesthetized, or with rigid endoscopy with the patient lightly anesthetized and spontaneously ventilating. The affected arytenoid cartilage is noted to prolapse anteriorly and medially with inspiration, partly obstructing the airway. If treatment is required, endoscopic laser partial arytenoidectomy is effective. In a series of 44 children who underwent CTR, 20 were noted to develop arytenoid prolapse after operation. Twelve were asymptomatic, and 8 required laser arytenoidectomy, 2 of whom now require continuous positive airway pressure for moderate supraglottic collapse.
