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.
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.
Based on clinical history, diagnosis and imaging, accessory maxilla with supernumerary teeth was diagnosed.
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.
副上颌是一种罕见病症，常与第7型特西埃腭裂相关，文献记载的病例不足25例。本文报告了1例伴有6颗多生牙的单侧副上颌病例。
一名5岁半的男孩，曾接受大口畸形治疗，在随访时经影像学检查发现有副上颌伴牙齿。该结构影响生长，因此计划手术切除。
根据临床病史、诊断及影像学检查，诊断为副上颌伴多生牙。
通过口内入路手术切除副结构及牙齿。愈合顺利。生长偏差得到纠正。
口内入路是切除副上颌的良好选择。第7型特西埃腭裂可能伴有第5型腭裂，当此类副结构影响颞下颌关节或面神经等重要结构时，应立即切除以促进正常形态和功能。
