OBJECTIVE : To assess the outcome of palate lengthening by myomucosal buccinator flaps for velopharyngeal insufficiency both in terms of speech and changes in palate length. DESIGN : Thirty-two consecutive patients who underwent the buccinator flap procedure were reviewed retrospectively. Palate length and the presence or absence of a velopharyngeal gap were assessed on pre- and postoperative videofluoroscopic recordings using a calibrated image analysis system. Hypernasality, nasal emission, nasal turbulence, and passive cleft type articulation errors were evaluated blindly by a speech-language pathologist external to the team using pre- and postoperative speech recordings. SETTING : Multidisciplinary cleft team based in a tertiary referral center. Results : In 81% of patients, speech outcome was such that no further velopharyngeal surgery was considered necessary at the time of follow-up. The buccinator flap procedure resulted in a mean palate lengthening of 7.5 mm (±5.5 SD). After the operation, there was a complete elimination of the velopharyngeal gap on lateral videofluoroscopy in 77% of patients. There were significant decreases in hypernasality ratings and passive cleft type articulation errors postoperatively. CONCLUSION: Palatal lengthening with myomucosal buccinator flaps in patients with velopharyngeal insufficiency is effective and safe. It has become one of our routinely practiced procedures for velopharyngeal insufficiency.
