Osteochondroma manifests as a benign tumor that occurs as an abnormal bony development. This tumor is commonly asymptomatic and presents an exophytic outgrowth on bone surfaces, near synovial joints, a condition that invariably induces evident facial deformities. Treatment for this type of tumor usually involves a surgical approach promoting a total or partial resection of the affected anatomical area associated to prosthetic reconstruction of the bone area extracted. We present a case report about a giant mandibular condyle osteochondroma in a 37-year-old female patient. Her treatment involved a total condylectomy without immediate condylar reconstruction, which would be performed in a posterior surgical approach. During the patient's follow-up (every 6 months of post operation), a spontaneous and rudimentary condyle-like formation was observed. Because the stomatognathic function and facial harmony were satisfactory, we observed the condyle-like development for 5 years of follow-up. Also, because both the aesthetic aspect and functional evolution of the maxillary bone were considered satisfactory, no complementary reconstruction surgical treatment was required for the giant osteochondroma of the mandibular condyle.
骨软骨瘤表现为一种良性肿瘤，是骨骼异常发育所致。这种肿瘤通常无症状，表现为骨表面、靠近滑膜关节处的外生性生长，这种情况总会导致明显的面部畸形。这类肿瘤的治疗通常采用手术方法，对受影响的解剖区域进行全部或部分切除，并对切除的骨区域进行假体重建。我们报告一例37岁女性患者的巨大下颌髁突骨软骨瘤病例。她的治疗包括全髁突切除术，未立即进行髁突重建，而是采用后路手术方法进行重建。在患者随访期间（术后每6个月），观察到自发的、初步的髁突样形成。由于口颌功能和面部协调性令人满意，我们对髁突样发育进行了5年的随访观察。此外，由于上颌骨的美学外观和功能演变均被认为令人满意，下颌髁突巨大骨软骨瘤无需进行补充重建手术治疗。
