Accessory Maxilla in a Tessier 07 Cleft - A Case Report

THE RATIONALE: Accessory maxilla is a rare condition often associated with Tessier type-7 clefts with fewer than 25 cases recorded in the literature. This manuscript reports a unilateral accessory maxilla with six supernumerary teeth. PATIENT CONCERNS: A 5-1/2-year-old boy, a treated macrostomia case, on follow-up visit showed evidence of accessory maxilla with teeth on radiological examination. The structure was interfering with growth, and hence, surgical removal was planned. DIAGNOSIS: Based on clinical history, diagnosis and imaging, accessory maxilla with supernumerary teeth was diagnosed. TREATMENT AND OUTCOMES: The accessory structures and teeth were removed surgically via an intraoral approach. Healing was uneventful. The growth deviation was arrested. TAKE-AWAY LESSONS: Intraoral approach is a good option to remove an accessory maxilla. Tessier type-7 cleft may be accompanied by type-5 clefts and such accessory structures when impinging on vital structures such as temporomandibular joint or facial nerve should be immediately removed to facilitate proper form and function.
