Abstract：
Tessier no. 7 clefts are characterized by macrostomia, facial muscular diastasis and maxillary and zygomatic bone abnormalities. It is caused by a lack of ectomesenchyme formation or penetration of the maxillary and mandibular processes during the fourth and fifth weeks of development. A case of bilateral transverse facial cleft with an accessory maxilla and an osseous choristoma is presented. The diagnosis of accessory maxilla was based on clinical findings due to the inaccessibility of orthopantomography and computed tomography scan. Orbicularis oris muscle reconstruction, cheiloplasty and excision of accessory maxilla were done. Histopathological examination of the bony lesion showed an osseous choristoma. There were no postoperative complications or local recurrence of the lesion excised. This case report demonstrates the importance of early diagnosis and intervention in maxillofacial congenital anomalies. Cheiloplasty restores function and gives the patient a natural appearance. The excision of accessory bone prevents further complications in the child\'s growth.
摘要：
Tessier号7个裂隙的特征是大口，面部肌肉扩张和上颌和颧骨异常。它是由于在发育的第四和第五周缺乏外植体形成或上颌和下颌突的渗透而引起的。提出了一例双侧横向面部left裂，伴有副上颌骨和骨性脉络膜瘤。副上颌骨的诊断是基于临床发现，这是由于矫形器造影术和计算机断层扫描无法接近。口轮匝肌重建，进行了唇缘成形术和副上颌骨切除术。骨病变的组织病理学检查显示骨性脉络膜瘤。术后无并发症或切除病灶局部复发。此病例报告证明了早期诊断和干预颌面部先天性异常的重要性。唇缘成形术恢复功能，给病人一个自然的外观。附件骨的切除可防止儿童生长中的进一步并发症。
