Use of buccal myomucosal flap in secondary cleft palate repair.

BACKGROUND: The purpose of this study was to assess the effectiveness of the buccal myomucosal flap in secondary repairs of cleft palate. METHODS: Twenty-two patients who underwent secondary palatoplasty between 1989 and 2004 in which a buccal myomucosal flap was used were reviewed retrospectively. All patients had undergone at least one previous attempted repair at other institutions. Indications for the secondary repair included velopharyngeal incompetence and/or oronasal fistula. Patients were evaluated preoperatively for oronasal fistula status, velopharyngeal competence, nasal resonance, speech quality, and nasal escape. RESULTS: The buccal myomucosal flap was used in all patients. The patients' mean age was 8.5 years (range, 1 to 23 years). Correction was indicated in seven patients with velopharyngeal incompetence (32 percent), five patients with oronasal fistulas (23 percent), and 10 patients with both conditions (45 percent). Preoperative assessment revealed four patients (18 percent) with an associated syndrome, 17 of 20 patients with hyperresonance (85 percent), 16 of 20 patients with nasal escape (80 percent), and 12 of 20 patients with poor speech (60 percent). The buccal myomucosal flap technique was used alone in 50 percent of patients, six patients had a staged correction (27 percent) and five patients required multiple procedures (23 percent). All fistulas remained closed. Two patients showed mild velopharyngeal incompetence (p = 0.001) and two patients continued to display hyperresonance (p < 0.001). Speech quality improved to a good level in 17 patients (77 percent) (p < 0.001). CONCLUSION: Palate re-repair combined with a buccal myomucosal flap, occasionally in conjunction with other techniques, is an effective method for correcting failed cleft palate repairs.

The buccal flap--a useful technique in cleft palate repair?

OBJECTIVE: To evaluate speech quality and oronasal fistula after primary palate repair using a buccal mucosal flap. DESIGN: Retrospective study cohort of patients with cleft palate. SETTING: Primary care center for treatment of craniofacial congenital anomalies. PATIENTS AND METHODS: One hundred fifty-six nonsyndromic patients underwent palatoplasty with the buccal myomucosal flap by the senior surgeon between 1989 and 2002. The preoperative workup, surgical technique, and other factors that might affect the outcome were identical in every case. Oronasal fistula and variables affecting speech quality were analyzed. RESULTS: The most common type of cleft was unilateral cleft lip and palate (43.5%). The median follow-up was 5.8 years (0.4 to 21 years), and the median age at repair was 6.2 months. The overall fistula formation was 3.6%, decreasing progressively: 1989 to 1994: 2.9%, 1995 to 2002: 0.7% (p <.05). Velopharyngeal incompetence (VPI) occurred in 8.8% of the patients, decreasing from 5.3% to 3.5% in the last years. VPI and oronasal fistulae were observed mainly in unilateral and bilateral clefts of the lip and palate. Velopharyngeal adequacy occurred in 91.1% of the children, and resonance was normal in 91.1 %. None of the patients had severe hypernasality or hyponasality. Articulation was normal in 97.9% of the children. Speech quality was good in 89% of the patients. CONCLUSIONS: The technique presented has been effective, with the advantages of palatal closure without tension, good muscular reconstruction, lengthening of the nasal layer, and palatal closure without raw areas. The technique, early repair, and surgeon's skills were the most important variables for good outcomes regarding speech and fistula formation.
