Background: Chondroblastomas, which account for approximately 1% of all bone tumors, typically occur in longbones, such as the femur, humerus, and tibia. However, in extremely rare cases, they may also occur in thecraniofacial region where the tumor is often found in the squamous portion of the temporomandibular joint (TMJ)and in the temporal bone. Case presentation: This case report describes a large chondroblastoma (diameter, approximately 37 mm) thatoccurred in the TMJ. The tumor was sufficiently aggressive to destroy the TMJ, mandibular condyle neck, externalauditory canal (EAC), mandibular fossa of the temporal bone, and facial nerve. The tumor was completely excisedusing a pre-auricular approach. The EAC and surgical defect were successfully reconstructed using atemporoparietal fascia flap (TPFF) and an inguinal free fat graft. There was no local tumor recurrence at the 18-month follow-up visits. However, the patient developed sensory neural hearing loss, and his eyebrow paralysisworsened, eventually requiring plastic surgery. Conclusion: Large, invasive chondroblastomas of the TMJ can be completely removed through a pre-auricularapproach, and the resulting surgical defect can be reconstructed using TPFF and free fat grafts. However, preoperativeevaluation of the facial nerve and auditory function is necessary. Therefore, a multidisciplinary approach is essential.

Background: The pedicled buccal fat pad has been used for a long time to reconstruct oral defects due to its easeof flap formation and few complications. Many cases related to reconstruction of defects in the maxilla, such asclosing the oroantral fistula, have been reported, but cases related to the reconstruction of defects in the mandibleare limited. Under adequate anterior traction, pedicled buccal fat pad can be a reliable and effective method forreconstruction of surgical defects in the posterior mandible. Case presentation: This study describes two cases of reconstruction of surgical oral defects in the posteriormandible, all of which were covered by a pedicled buccal fat pad. The size of the flap was sufficient to perfectlyclose the defect without any tension. Photographic and radiologic imaging showed successful closure of thedefects and no problems were noted in the treated area. Conclusion: In conclusion, the pedicled buccal fat pad graft is a convenient and reliable method for thereconstruction of surgical defects on the posterior mandible.
