Transverse infrahyoid approach to bilateral glottic tumors.

Glottic exposure and entry for vertical partial laryngectomy procedures has traditionally been through the subglottis. Although this approach is generally satisfactory for the resection of unilateral vocal cord lesions, it may be unsafe in cases in which tumors extend across the midline and/or subglottically. In these instances, we prefer the superior transverse infrahyoid approach to the glottis, which transects the petiole of the epiglottis and reflects the contents of the preepiglottic space posterior and superior. This improved visualization of the larynx has permitted precise tumor excision without sacrifice of uninvolved segments of the vocal cords. This procedure has been performed 35 times over a 15-year period at our institution for the resection of bilateral glottic tumors, with and without subglottic extension. In none of the cases in which it has been employed was there a positive surgical margin.
