A Method for Reconstruction of Anterior Commissure Glottal Webs With Endoscopic Fibro-Mucosal Flaps.

BACKGROUND:: Anterior-commissure (AC) cicatrization and web formation is a difficult problem that can result from a variety of clinical scenarios. An advancement-rotation flap utilizing papillomatous epithelium and subepithelial fibrous tissue has been previously described. For patients in whom there was not excessive redundant papillomatosis covering the AC web, including other clinical scenarios, a microlaryngoscopic procedure was designed to lengthen the glottal/subglottal aperture using substantial local fibro-mucosal tissue. Although it has been done for over a decade, this approach is not widely known and to our knowledge not photo-documented.

STUDY DESIGN:: Retrospective.

MATERIAL AND METHODS:: An analysis was done with Institutional Review Board approval that identified 42 patients who underwent 53 procedures to treat AC webs, which were reconstructed with local soft-tissue flaps and without any device/stent to maintain the glottal aperture. The microlaryngoscopic method and technical nuances for this approach with and without diseased epithelium are described and photo-documented. Tactical mucosal incisions were made to facilitate advancement and/or rotation of fibro-mucosal flaps with enough length to resurface the medial aspect of 1 vocal fold. The scarred submucosal soft tissue in the AC region was separated with cold instruments, and the flaps were sutured in position. Variations of this method are demonstrated mobilizing fibro-mucosal soft tissue from different locations, including the web itself, contralateral vocal fold, infrapetiole region, and/or the inner aspect of the thyroid lamina below the anterior-commissure tendon.

RESULTS:: Of the 53 cases in which anterior commissure glottal webs were reconstructed with endoscopic fibro-mucosal flaps, 31 of 53 had recurrent respiratory papillomatosis (RRP). Redundant RRP comprised the majority of the flap in 14 of 31 RRP cases. Fibro-mucosal tissue without a substantial amount of disease occurred in 17 of 31 RRP cases. Of the remaining 22 AC web cases, the primary diagnoses observed were: glottic cancer = 7 of 22, intraepithelial dysplasia = 10 of 22, glottic trauma = 3 of 22, congenital = 1 of 22, and radiotherapy = 1 of 22.

CONCLUSION:: Endolaryngeal utilization of local fibro-mucosal tissue to lengthen the glottal/subglottal aperture for AC webs is an effective strategy. It can be done without using devices or keels for webs that are congenital or from nonsurgical trauma, idiopathic disease, or postsurgical traumatic cicatrization of the anterior commissure subsequent to treatment of epithelial disease (eg, cancer, dysplasia, and RRP). Normalizing the architecture of the anterior commissure was a valuable asset in patients who require future treatment of epithelial diseases, especially in an office-based setting.
