Islanded facial artery musculo-mucosal flap for partial pharyngeal defect reconstruction after total laryngectomy: Case report.

BACKGROUND

Partial pharyngeal defect reconstruction after total laryngectomy with regional and free fasciocutaneous flaps has been described. However, mucosal flaps for such defects have not been reported.

METHODS

An islanded facial artery musculo-mucosal (FAMM) flap was used to reconstruct a partial pharyngeal defect after total laryngectomy. Surgical, swallowing, and speech outcomes were analyzed at 6 months postoperatively.

RESULTS

At 6 months, videofluoroscopy showed no post swallow residue, fistula, trachea-esophageal puncture leak, or stricture. Perceptual analysis of recorded cold speech, native language passage sample, and the intelligibility analysis was good. The patient had normal mouth opening and marginal mandibular nerve function.

CONCLUSION

Islanded FAMM flap is ideal for partial pharyngeal defects, which cannot be closed primarily. Speech and swallowing outcomes were good. It provided a robust and predictable blood supply and adequate reach. There was no significant donor site morbidity. The musculo-mucosal flap replaced "like-with-like" tissue.
