The aim of this study is to evaluate donor site morbidity and buccinator muscle integrity following the use of buccinator myomucosa flap in patients with velopharyngeal incompetence.
Cleft lip and palate represent one of the most common congenital deformities. The associated disruption of palatal structure leads to abnormal velopharyngeal anatomy, frequently resulting in failure to achieve adequate closure of the velopharyngeal valve even after primary palatal repair.
Buccal artery myomucosal flap Firstly described by Bozola this axial-pattern flap is based on and centered around the buccal artery, a branch of the internal maxillary artery. The flap extends from the maxillary tuberosity to the oral commissure and is primarily used for the closure of mucosal defects involving the posterior hard palate, soft palate, and maxillary alveolus.

This study is a prospective comparative and retrospective study designed to evaluate the donor site morbidity and buccinator muscle integrity after buccinator myomucosal flap in patients with velopharyngeal incompetence
Exclusion Criteria:
Patients with velopharyngeal incompetence undergoing palatal lengthening using bilateral posteriorly based buccinator myomucosal flaps.
Procedure: Bilateral posteriorly based buccinator myomucosal flap surgery
Palatal lengthening will be performed using bilateral posteriorly based buccinator myomucosal flaps in patients with velopharyngeal incompetence.
Buccinator muscle functional integrity
Buccinator function will be assessed by the 10-second cheek puff test to retain air for 10 seconds. The examiner will record whether the participant completes the test and whether air leakage or facial asymmetry is observed.
Time frame: 3 months after surgery
Plan to share: Yes — The data will be available upon a reasonable request from the corresponding author after the end of study for one year.
