Introduction:The use of a buccinator myomucosal flap in combination with Furlow's Z-plasty during primary and secondary palatal repairs has been proposed by many authors to overcome some of the limitations of Furlow's technique. However, there have been no studies that quantitatively measured the effective palatal lengthening when the buccal flap is added. Patients and Methods: The buccal flap is routinely used during primary palate repair in order to fill the gap between the hard palate and reoriented palatal muscle sling. The soft palatal length was measured in the midline from the posterior edge of the hard palate to the base of the uvula. All patients were measured before starting the surgery and just after palatal closure in the standard position for cleft palate repair. Results: Seventy-three patients with cleft palate who were candidates for primary repair were included. The mean age at the time of operation was 11.4 ± 3.5 months. The mean preoperative palatal length was 21.36 ± 3.529 mm, whereas the mean postoperative palatal length was 29.64 ± 4.171) mm. The mean palatal length change was 8.29 ± 2.514 mm (P < 0.000). Conclusions: The Combined use of a buccinator myomucosal flap with modified Furlow's Z-plasty in primary cleft palate repair has proven effective for palatal lengthening and achieved tensionless closure without the need for relaxing incision. It also provided a pliable soft tissue attachment of the palatal muscles to the hard palate allowing for better muscle function and mobility.
