Agenesis of the temporomandibular condyle is a congenital/developmental disorder that can present with the absence of the condyle and an incomplete development of the articular fossa and eminence, resulting in facial asymmetry as well as masticatory dysfunction. The purpose of this report is to present the case of a three-year-old girl with absence of the left temporomandibular condyle. The patient presented with pain and dysfunction in the left masseter muscle, pre-auricular area and ear as well as mild chin deviation to the left. The most common treatment modality is to wait and treat this condition with surgical intervention once the patient is grown. However, oral orthopedic appliances can be considered to promote bone formation prior to surgery. Prompt recognition and early treatment is advisable to take advantage of the child's growth and avoid further facial asymmetry, pain and dysfunction.
颞下颌关节窝发育不全是一种先天性/发育性疾病，其特征为下颌骨髁突缺失以及关节窝和关节结节发育不全，从而导致面部不对称和咀嚼功能障碍。本报告旨在介绍一例 3 岁女孩左侧下颌骨髁突缺失的病例。患者表现为左侧咬肌、耳前区和耳部疼痛和功能障碍，以及轻度左侧下颌偏斜。最常见的治疗方法是等待，一旦患者成年后再通过手术干预进行治疗。然而，在手术前可以考虑使用口腔矫形器来促进骨骼形成。建议及时识别和早期治疗，以利用儿童的生长发育，避免进一步的面部不对称、疼痛和功能障碍。
