Objective: This is a preliminary study of the endoscopic technique on open surgery. The purpose of this study is to introduce the use of endoscopic technique for the reconstruction of the condyle with costochondral graft through a preauricular incision.
Methods: 33 patients of temporomandibular joint diseases (n=49) underwent reconstruction of mandibular condyle with costochondral graft. After preparation of the recipient site through a preauricular incision, maxillo-mandibular fixation, and preparation of the costochondral graft, the graft was fixed to the lateral side of the mandible ramus under the supervision of arthroscope.
Results: All the patients had successful reconstruction of the condyle with costochondral graft without any severe bleeding or craniocerebral injury.
Conclusion: This case series demonstrates the feasibility of endoscopic technique for the reconstruction of the condyle through a preauricular incision. It has the advantage of high efficiency, minimal postoperative morbidity, great patient comfort, and little appearance impairment. The endoscopic technique has a promising future.

Odontogenic myxoma of the mandibular condyle is a rare tumor that requires complete surgical resection because of the tendency for recurrence. The right mandibular condyle was resected to remove the myxoma. The author performed immediate condylar reconstruction using a costochondral graft (CCG), and stable temporomandibular joint (TMJ) function and occlusion were achieved.

: Defects of the ascending ramus of the mandible, including the condylar head and neck or the whole temporomandibular joint (TMJ), are difficult to reconstruct. Reconstruction is mainly based on the use of alloplastic joint prosthesis, costochondral grafting, distraction osteogenesis of the dorsal part of the mandibular ramus, or osseous microvascular flaps of various origin. With the objective of developing a method that overcomes the restrictions of these methods, we recently introduced a sequential chimeric flap consisting of a lateral femoral condyle flap (LFC) and deep circumflex iliac artery flap (DCIA) for reconstruction of up to half of the mandible and the condylar head and neck.

Mandibular condyle aplasia and temporomandibular joint (TMJ) ankylosis represent complex challenges in diagnosis and management, affecting jaw function and facial aesthetics. This case report presents a five-year-old female child with a right-sided small jaw and facial asymmetry due to left-sided TMJ ankylosis. The coexistence of mandibular condyle aplasia and TMJ ankylosis underscores the need for comprehensive evaluation and tailored treatment approaches.
