RESUMEN
OBJECTIVE: To appraise the degree of intraoperative palatal lengthening with the modified Furlow small double-opposing Z-plasty (sDOZ). DESIGN: Retrospective single-surgeon (R.D.) study. PATIENTS: Nonsyndromic children (n = 167) with Veau types I to IV cleft palates who underwent primary sDOZ palatoplasty. INTERVENTIONS: Intraoperative measurements of palatal lengths and widths were collected using calipers, paper rulers, and metal rulers before the administration of local anesthetic solution and before the removal of the mouth gag (initial and final palatal dimensions, respectively). MAIN OUTCOME MEASURES: Assessment of the intraoperative percentage change (difference between final and initial values) in surface palatal length, straight palatal length, and soft palatal length. Bivariate and multivariate analyses were performed to identify independent predictors (sex, age at surgery, Veau, Kernahan/ Stark, and Randall classifications, widest cleft width, presence of lateral relaxing incision, type of coverage with buccal fat flap, and postoperative complications) of soft palatal lengthening. RESULTS: Surface palatal, straight palatal, and soft palatal lengths had an intraoperative increase of 8%, 14.7%, and 27.7%, respectively. The degree of intraoperative soft palatal lengthening significantly varied among Veau cleft types (I = II < III = IV). Veau type III and cleft lip/palate were independent positive predictors (P < .001) of soft palatal lengthening, while other tested variables were not correlated (P > .05) with this outcome. CONCLUSIONS: Overall intraoperative palatal lengthening occurs with the modified sDOZ palatoplasty, with differences within the spectrum of cleft palate deformity.
