title: Musculo-nasomucosal unit with complete lateral bony freeing and medial rotation for ideal C-shape restoration and retropositioning of the levator veli palatini.
abstract: No definitive procedure for cleft repair has been identified yet as the gold standard. Accordingly, this work tried to appraise the hypothesis that if the bony detachment and full retropositioning of the levator veli palatini muscle can ideally present an anatomical C-shape muscular sling restoration and if this is accompanied with pushback palatoplasty, would this present a better result in terms of tissue fistulation and phonetic impairment? A series of 74 different degrees of palatal clefts were operated by pushback palatoplasty combined with a modified approach of the levator vili palatini. This muscle was dissected only from the oral mucosa while kept attached to the nasal one as a musculo-nasomucosal unit. This unit was completely detached from the bony margin of the hard palate and then medially rotated and retropositioned in a typical C-shape mobile sling. Evaluations included suture line assessment and fistula development, and following the child's need for speech therapy. There were no intraoperative complications. Definite anterior fistulae with nasal air and foot leakage were observed in 2 cases. Four cases had postoperative velopharyngeal incompetence with a need for speech therapy. Tension-free closure, lower risk of fistula, good restoration of velopharyngeal functions, ability to be performed on all cleft types, ability to provide a good intraoperative exposure, and being a single stage seem to be the most important advantages of this unpublished technique.
