RESUMEN
OBJECTIVE: Numerous methods and materials are available for vertical partial laryngectomy. In this study, the reparative effects of the platysma myocutaneous flap (PMF) and ribbon myocutaneous flap (RMF) on the postoperative voice quality of patients were compared to provide a reference for selecting a method conducive to improving postoperative voice quality. METHODS: A retrospective analysis was performed on patients with unilateral T2-3 glottic carcinoma. Following vertical partial laryngectomy, the defect was repaired with a PMF or simple RMF. Twelve months after surgery, voice quality was assessed according to voice acoustics, aerodynamics, and subjective perceptual evaluation, and glottic morphology was recorded using a laryngeal stroboscopy. RESULTS: A total of 70 patients were identified, including 54 in the PMF group and 16 in the RMF group. The PMF group was superior to the RMF group in terms of voice quality assessed by voice acoustics, aerodynamics, and subjective perceptual evaluation. In the PMF group, 72.2% of patients performed phonation with their vocal cords, and approximately 27.8% of patients were affected by supraglottic compression. In the RMF group, 81.3% of patients were affected by supraglottic compression. No significant difference was found in the 5-year survival rate between the two groups. CONCLUSION: For defect repair following vertical partial laryngectomy, a PMF can allow better postoperative voice quality to be achieved than an RMF because a PMF can provide more tissue (including strap muscle under the flap) for padding, which enables the glottic portion corresponding to the vocal cord to close well.
