Abstract
Cleft palate is a common congenital anomaly of the craniofacial region. The primary approach for correction of cleft palate is surgery that provides the patients with cleft palate the required management. Intravelar veloplasty is a procedure for correcting cleft palate that depends on dissection and retro-positioning of levator palati muscle from the posterior line of hard palate and mucosa of nose and mouth. Velopharyngeal insufficiency requires palatal re-repair procedure which depends on complete dissection and repositioning of the velar muscles to farther posterior functional line leading to velar elongation. The present study aimed to evaluate the microscopic surgical repair of CP with IVVP on a clinical and radiological basis.
Methods: The study was conducted using a quasi- experimental study design on 35 patients, of which 21 patients underwent primary intravelar veloplasty repair and 14 patients underwent palatal re-repair. Postoperative outcomes were assessed clinically as occurrence of complications, while the radiological measurements were assessed using lateral video fluoroscopy and nasopharyngoscopy.
Results: The study conducted on 35 patients; 54.3% females with a median age of 4.33. Sixty percent of patients had incomplete cleft palate prior to surgery and postoperative complications were seen among 14.3% of patients in the form of fistula and infection (11.4%) and hemorrhage (2.9%). The lateral video fluoroscopy and nasopharyngoscopy showed a significant difference after surgery in all parameters. Fresh and redo cases showed no significant difference in the parameters of nasopharyngoscopy except for closure ratio change and lateral video fluoroscopy except for resting and contracting gaps changes.
Conclusion: Intervelar veloplasty technique is a very useful procedure in repairing primary and re-repaired cleft palate with minimal complications. It had a significant effect on the morphological details of the palate and velopharyngeal valve..
