Abstract

Introduction : Orofacial clefts have a wide spectrum presentations. It is mostly presenting as cleft lip with or without cleft palate. The optimal management of a case with cleft lip requires a multidisciplinary approach involving multiple specialties. The concept of presurgical orthodontics, including NAM (nasoalveolar molding), has been introduced in order to improve the outcome of lip repair.
Aim of the work : The aim of this study is to evaluate the effect of NAM on orbicularis oris muscle dimensions and the impact of this effect on the outcome of surgical repair of unilateral cleft lip at the Pediatric Surgery Department, El Shatby Children’s Hospital, Smouha Children’s Hospital, Alexandria University, Egypt.
Patients : This prospective case series study was conducted on 20 patients diagnosed as complete unilateral cleft lip . Patients with microfrom cleft lip, cleft face and bilateral cleft lip were excluded from this study.

Methods : Each case underwent NAM starting from 2 weeks after birth. Modified Millard repair was performed on each case. Three measurements were taken : philtral length, nasal width, alar base position at three different periods : pre NAM, post NAM and postoperative. The measurements were compared between the pre NAM and post NAM periods and between the post NAM and postoperative periods.
