Palatal Lengthening Using Buccinator Myomucosal Flaps with Furlow Z-plasty Technique for Primary Cleft Palate Repair (A Clinical Study)

: Cleft palate is a congenital deformity caused by abnormal facial development during intra-uterine life. Worldwide, the prevalence of cleft lip/palate is about 1:1000 live births.

The levator vela palatini muscles are malpositioned sagittally, running postero-anteriorly and inserted onto the posterior edge of the hard palate in cleft palate patients . This configuration prevents the muscle from exerting its upward, backward, and lateral pull.

Various modalities have been described with major refinements over the past 30 years. Gradually, cleft surgeons began to appreciate the importance of dissection and retro-positioning of the levator muscle on improving speech outcomes.

Furlow was the first to describe the palatoplasty technique, in which the levator muscle is dissected and freely released from its abnormal position and retro-positioned in a Z-plasty lengthening technique without dissection on the hard palate. However , among the problems that have been raised concerning the Furlow palatoplasty is the limitation of the procedure in wide clefts. Furthermore, the possibility of higher fistula rate associated with the technique.

These considerations have led to modified palatal lengthening by buccinator myomucosal flaps which is this study working on.
