Abstract
Objectives: The Isshiki arytenoid adduction procedure directly closes the open posterior glottis. Postoperative airway obstruction that necessitates emergent tracheotomy is an important complication in arytenoid adduction patients when the standard posterior thyroplasty window is used to approach the posterolateral larynx. Immediate postoperative fiberoptic laryngoscopy shows ipsilateral edema and/or hematoma of the arytenoid and supraglottic mucosa, with occasional obstructing inspiratory collapse. In this study, I sought to modify the posterior window approach during arytenoid adduction surgery, and thereby decrease the incidence of immediate postoperative airway obstruction. Methods: I performed a retrospective chart review of 246 arytenoid adduction patients, looking for immediate postoperative airway compromise. Results: There were no episodes of postoperative airway obstruction that necessitated tracheotomy in the first 30 patients in whom I approached the posterolateral larynx using the classic Isshiki techniques. Nine of the succeeding 132 adduction patients required emergent tracheotomy when the standard posterior window technique was used instead of a classic Isshiki approach (6.8%). In the most recent 84 patients, I used one tacking suture to stabilize the elevated pyriform sinus mucosa to the upper margin of the posterior window cartilage at closure. Four of the 84 patients had audible postoperative airway turbulence that abated with medical treatment, and 1 patient required an emergent tracheotomy (1.2%; p = .0495). Conclusions: Suture stabilization of the pyriform sinus mucosa is effective and is recommended for prevention of posterior glottic airway obstruction after arytenoid adduction when the posterior window technique is used.
