A novel technique for prevention of anterior fistula and facilitation of alveolar cleft repair: Gingivoperiosteoplasty with palatoplasty

Background & Objectives: The Cleft palate is one of the most commonly encountered congenital deformity in plastic surgery clinics and can be associated with cleft lip and alveolus. Though palate repair can be associated with several complications, the most frequent and troublesome is anterior fistula formation. Various technical modifications are in practice to avoid this dreaded complication. We have started combining gingivoperiosteoplasty with palate repair to avoid postoperative anterior fistula formation and to close alveolar cleft at the same time.

Methods: A prospective study was performed at the department of plastic and reconstructive surgery, Liaquat National Hospital, Karachi and selected patients were enrolled in the study after informed consent. A total of 15 patients were operated on from January 2017 to December 2020. All patients had cleft palate repair along with primary gingivoperiosteoplasty (GPP) at the age of standard palatal repair. Buccal/oral and nasal layers of the alveolus were dissected as per standard gingivoperiosteoplasty and repaired in continuation with nasal and oral layers of the palate. Postoperatively, the standard cleft palate repair protocol was followed. Follow-up was done at four weeks, 12 weeks, and six months and repair integrity was checked. Future follow-up at 4-5 years of age is planned to see the effect on alveolar collapse, bone growth, and the need for secondary bone grafting.

Results: All patients were followed up regularly. None had a complication of fistula. The repairs of both palate and alveolus remained intact. Patients were kept on the follow-up to assess the need for alveolar bone grafting in the future.

Conclusion: Gingivoperiosteoplasty combined with the palatal repair is a novel technique for the prevention of anterior palatal fistula.
