Intravelar Veloplasty Performed without an Incision in the Nasal Mucosa in a Patient with Submucous Cleft Palate: A Case Report

A submucous cleft palate (SMCP) results from a lack of normal fusion of the muscles within the soft palate. A SMCP is characterized by a bifid uvula, deficient midline muscle with zona pellucida, and osseous notch of the hard palate. When a submucous cleft is present, the muscles of the soft palate may not function properly which places a person at risk for speech problems (such as a hypernasality), middle ear disease, and swallowing difficulties. A SMCP requires surgery, if it causes problems. A velopharyngeal incompetence is a condition which a person cannot prevent air from escaping through the nose during the speech, and requires surgical repair of the palate. Intravelar veloplasty involves reconstruction of the abnormal soft palate muscles, tensor and levator veli palatine muscle. During the surgery, tensor and levator veli palatine muscles were separated from their abnormal attachment and from the oral and nasal mucosa. In this case report, we present a 48 months old child with SMCP who underwent intravelar veloplasty without separating the nasal mucosa.
