과대비성을 동반한 점막하구개열 환자에 대한 Double Opposing Z-plasty를 통한 수술적 치료 결과
Outcomes for Patients with Submucous Cleft Palate Accompanying Hypernasality Treated with Double Opposing Z-plasty
초록
Submucous cleft palate is a relatively uncommon congenital anomaly accompanying velopharyngeal incompetence(VPI). Double opposing Z-plasty has many advantages including prolongation of soft palate, normal midfacial growth, midline scar. We analyzed postoperative results comparing with those of preoperative evaluation by several variables(nasometer, endoscopy, satisfactory scale) in 14 patients treated with double opposing Z-plasty due to submcous cleft palate. Nasalance score in Ah sound, Ma phrase, and Pa phrase decreased 20.23%, 3.25%, and 23.26% in the average, respectively. As a result, hypernasality improved significantly. Closure rate in velum evaluated by endoscopy was increased from 0.44 to 0.76. In objective satisfactory scale checked by each patient's guardian at the postoperative period, much improved in 3, improved in 6, minimally improved in 1, and no difference in 1 was reported. (n=11 patients) Double opposing B-plasty is a good surgical modality in patients accompanying VPI with submucous cleft palate or incomplete cleft palate and will be used more usefully and widely.
