Posterior Pharyngeal Flap for Velopharyngeal Insufficiency Patients: A New L-Shaped Flap.

Abstract

To describe and assess the results of central inset L-shaped posterior pharyngeal flap (PF) for treatment of velopharyngeal incompetence. This study included 12 patients who were diagnosed as persistent velopharyngeal insufficiency. L-shaped central inset superiorly based PF was harvested from oropharynx and inserted into the soft palate through a transverse full-thickness palatal incision 1 cm behind the posterior margin of the hard palate, then the flap was spread 1 cm horizontally and 1 cm in the anteroposterior direction in soft palate. Before and after surgery, patients were assessed by examination, video: nasoendoscopy, and speech assessment. Postoperative speech assessment showed significant improvement in the nasal emission, resonance, intraoral pressure, and articulation defects. Grade 4 velopharyngeal valve closure (complete closure) could be achieved in all patients. No patients showed dehiscence (partial or total) of the flap and no obstructive sleep apnea reported. The new used L-shaped PF could properly correct velopharyngeal functions (closure and speech) in patients with persistent velopharyngeal insufficiency with no reported complication.
