CPT® Code 42227

The procedure described by CPT® Code 42227 involves the lengthening of the palate using an island flap technique, specifically a buccinator sandwich flap. This surgical intervention is typically indicated for patients with conditions that necessitate the reconstruction or lengthening of the palate, often to improve function or aesthetics. The island flap technique utilizes bilateral buccinator flaps, which are created from the buccinator muscle located in the cheeks. The procedure begins with the careful outlining of the flaps on the midpart of each cheek, ensuring that the flaps are positioned below the parotid duct opening. The mucosa and full-thickness buccinator muscle are then raised in a controlled manner, preserving the blood supply from the buccinator artery, which is crucial for the viability of the flaps. This meticulous approach allows for the successful suturing of the first flap into the nasal layer, followed by the second flap being placed over it into the oral layer of the defect. The donor sites are subsequently closed with sutures, completing the procedure. This technique is essential for addressing specific palatal defects and enhancing the overall quality of life for patients requiring such surgical interventions.
