Abstract：
Osteochondroma (OC) is an uncommon reason for the mandibular condyle to grow excessively. Usually unilateral, it can impact the entire mandible, the condyle and ramus, or just the condyle. It is a bony projection covered in cartilage that protrudes from the damaged bone\'s exterior. Condylar OC are more prevalent as a result of endochondral ossification-related development. The most notable characteristic is the gradual asymmetry of the face over time. Clinical symptoms of the patient include pain, asymmetry, malocclusion, partial or total hearing loss, trismus, and hypomobility of the TMJ. We report a case of 40-year-old male patient complaining of reduced mouth opening since last 10 years. Clinical examination revealed gross facial asymmetry, hard swelling over right TMJ, jaw deviation towards left side, restricted mouth opening of 3 mm and deranged occlusion. An irregular radiopaque mass was seen over the right condylar region in OPG. A large, hyperdense mass that obliterated the sigmoid notch and extended medially to the right condyle was visible on CT scans. Using a pre-auricular Alkayat-Bramley technique, the mass was surgically removed. Occlusal corrections and jaw physiotherapy were then administered. On follow up, deviation was corrected and adequate mouth opening was achieved.
摘要：
骨软骨瘤（OC）是下颌髁突过度生长的不常见原因。通常是单方面的，它会影响整个下颌骨，髁和棘，或者只是髁.它是覆盖在软骨中的骨突起，从受损骨的外部突出。由于软骨内骨化相关的发展，con突OC更为普遍。最显着的特征是面部随着时间的推移逐渐不对称。患者的临床症状包括疼痛，不对称，错牙合,部分或全部听力损失，刺耳,和TMJ的低灵活性。我们报告了一例40岁的男性患者，自过去10年以来一直抱怨张口减少。临床检查显示面部严重不对称，右侧TMJ硬肿,下巴偏向左侧,限制3毫米的张口和错乱的闭塞。在OPG的右髁区域上看到不规则的不透射线的肿块。一个大的，在CT扫描中可见高密度肿块，该肿块消除了乙状结肠切迹并向内侧延伸到右髁。使用耳前Alkayat-Bramley技术，手术切除了肿块。然后进行咬合矫正和下颌理疗。在后续行动中，校正了偏差，并实现了足够的张口。
