OBJECTIVE: To report our experience of @entity1 with type 1 @entity1728 , (including low inter-arytenoid height) who failed conservative management over a five year period. We describe the diagnostic elements of the history, examination at laryngobronchoscopy and provide a management algorithm including the use of inter-arytenoid submucosal injection of gelfoam as a temporary therapeutic as well as diagnostic tool. METHODS: A retrospective case note review over a five year period was undertaken to review all cases of type 1 @entity1728 who failed conservative management. Presenting symptoms, diagnostic procedures, surgical interventions and clinical outcomes were reviewed. RESULTS: Seventeen @entity1 were identified. Chronic cough was the most consistent feature in the history (100%). All @entity1 underwent a microlaryngoscopy with binocular microlaryngeal assessment. Six @entity1 (35%) underwent gelfoam injection; four of these went on to a formal repair. The remaining 11 all had a repair performed without injection. The success of surgical repair was 80% (12/15) however in the other three, all had improvement in symptoms. CONCLUSIONS: Type 1 @entity1728 may extend beyond that described by Benjamin and Inglis. An appropriate history as well as binocular inspection at the time of laryngoscopy is essential. Injection augmentation offers a safe tool in the assessment and management, and endoscopic surgical repair remains the standard for definitive therapy in those that fail conservative management.

Low inter-arytenoid height: A subclassification of type 1 XXXX diagnosis and management.
