Abstract: OBJECTIVES: Current surgical treatment for a glottic cancer with significant subglottic extension is a total laryngectomy. The objective of this study was to expand laryngeal conservation procedures by using a reconstructive technique that allows for the repair of hemicricolaryngectomy defects. STUDY DESIGN: After resection of the ipsilateral thyroid, cricoid, and arytenoid for advanced T3 glottic cancer, the laryngeal defect was reconstructed by means of an autotransplanted segment of trachea in four patients. The reconstruction consisted of a transferable patch that was constructed from a segment of revascularized cervical trachea. METHODS: During a 14-day period, a 4-cm segment of cervical trachea was wrapped by a free radial forearm fascial flap. In the second stage, the glottic cancer was removed and the cervical trachea was isolated on its fascial blood supply and transformed into a patch that was used to repair the extended hemilaryngectomy defect. Two different patch designs were used. Two patients underwent reconstruction with a patch augmented at the glottic level (group A); two patients underwent reconstruction without glottic augmentation on the patch (group B). Tracheal continuity was restored by an end-to-end reanastomosis. The postreconstruction morphology of the two patch designs was compared with the preoperative laryngeal morphology. RESULTS: The autotransplantation technique led to complete restoration of the subglottic airway lumen in all four patients. Although the anterior-posterior glottic diameter was reduced by 36% in group A patients and by 43.5% in group B patients, a sufficient glottic airway lumen was obtained. The glottic sphincteric function was restored in both groups. CONCLUSIONS: Tracheal autotransplantation may be used reliably to repair hemicricolaryngectomy defects. Augmentation of the patch at the level of the glottis is not essential for successful rehabilitation.
