半颜面增生(HFH)是一种罕见的先天性疾病,其特征是面部组织明显的单侧过度生长。HFH的一种亚型是先天性面部浸润性脂肪瘤病(CIL-F)。这种疾病的特征是面部软组织中成熟脂肪细胞的单侧弥漫性浸润,并与骨骼肥大有关。这项工作旨在报告一例aCIL-F患者,在青春期出现右侧面部不对称和进行性生长,由于伴随的单侧髁突增生的迹象导致下颌不对称。十七岁时,进行了髁突切除术以阻止不对称下颌骨生长的进展.五年后,患者发生CIL-F相关颞下颌关节强直,表现为进行性张口受限和颞部面部疼痛。在这个CIL-F患者中,使用同种异体全关节假体的TMJ重建成功地进行了最佳的最大张口,完全缓解颞部面部疼痛,术后1年牙齿咬合稳定。具有完整的同种异体全关节假体的TMJ重建被证明是可预测的,稳定,1例CIL-F相关的颞下颌关节强直患者因进行性下颌骨不对称性而曾接受过髁突切除术治疗,且可选择安全的治疗方案。
Hemifacial hyperplasia (HFH) is a rare congenital disorder characterized by marked unilateral overgrowth of the facial tissues. A subtype of HFH is congenital infiltrating lipomatosis of the face (CIL-F). This disease is characterized by unilateral diffuse infiltration of mature adipose cells in the facial soft tissue and is associated with skeletal hypertrophy. This work aims to report a case of a CIL-F patient with right facial asymmetry and progressive growth at adolescent age, causing mandibular asymmetry due to signs of concomitant unilateral condylar hyperplasia. At the age of seventeen, a condylectomy was performed to stop the progression of asymmetric mandibular growth. Five years later, the patient developed CIL-F-associated temporomandibular joint ankylosis, manifesting as progressive restricted mouth opening along with temporal facial pain. In this CIL-F patient, a TMJ reconstruction with an alloplastic total joint prosthesis was successfully performed with optimal maximal mouth opening, complete alleviation of temporal facial pain, and stable dental occlusion one year postoperatively. A TMJ reconstruction with a complete alloplastic total joint prosthesis proved to be a predictable, stable, and safe treatment option in a patient with CIL-F-associated TMJ ankylosis who was previously treated with condylectomy due to progressive mandibular asymmetry.
