Anesthesia/facial painCan a Novel Surgical Approach to the Temporomandibular Joint Improve Access and Reduce Complications?

Patients and Methods
This retrospective evaluation consisted of a consecutive series of patients who underwent TMJ surgeries through the VMPA at the Department of Oral and Maxillofacial Surgery, Shanghai Ninth People's Hospital, Shanghai JiaoTong University School of Medicine (Shanghai, China) from January through December 2013. To be included in the study sample, the patient must have undergone TMJ surgery only through the VMPA and had no history of TMJ surgery. Those patients who underwent TMJ surgeries through a
Results
All 475 patients (606 joints) had successful TMJ surgeries only through the VMPA, including open disc repositioning and anchorage fixation (n = 392 joints), disc replacement with a temporalis myofascial flap (n = 55 joints), resection of tumorous or tumorlike lesions (n = 45 joints), open reduction and fixation of condylar fractures (n = 42 joints), ankylotic bone resection and arthroplasty (n = 31 joints), condylar replacement with a costochondral graft (n = 26 joints), eminence augmentation
Discussion
According to the results of this study, different TMJ surgeries were performed successfully through the VMPA and there was no permanent weakness of the facial nerve or other severe complications. This indicates that the VMPA can produce appreciable improvement in access to the TMJ region by developing multilayer flaps while leaving the auriculotemporal nerve and superficial temporal artery and vein in situ and can provide a safe and efficient way to locate and protect the facial nerve using the
