CPT® Code 42260

A nasolabial fistula is defined as an abnormal communication or opening that occurs between the upper lip and the nose. This condition is often seen as a complication following cleft palate repair surgeries. The presence of a nasolabial fistula can lead to various functional and aesthetic issues, necessitating surgical intervention. The procedure described by CPT® Code 42260 involves a meticulous surgical approach to repair this abnormal opening. During the operation, the intraoral aspect of the lip is carefully divided to expose the nasolabial fistula. The surgical team elevates the nasal mucosa, which is the lining of the nasal cavity, and trims the mucosal edges of the fistula to prepare for closure. The edges are then approximated using sutures to effectively close the nasal floor. Additionally, a flap of mucosa is elevated from the area adjacent to the labial aspect of the fistula and rotated over the defect to ensure proper coverage and healing. Finally, the defect is secured with sutures, completing the repair process. This procedure aims to restore normal anatomy and function, thereby improving the patient's quality of life.
