Preliminary clinic study on computer assisted mandibular reconstruction: the positive role of surgical navigation technique.

Background: The objectives of the present study were to investigate the reliability and outcomes of computer-assisted techniques in mandibular reconstruction with a fibula flap and verify whether the surgical navigation system was feasible in mandible reconstructive surgery.

Methods: Eight cases were enrolled in the computer assisted surgery (CAS) group and 14 cases in the traditional group. The shaping and fixation of the fibula grafts were guided by computer assisted techniques, which could be monitored with the BrainLAB surgical navigation system.

Fibular free flap reconstruction for the management of advanced bilateral mandibular osteoradionecrosis.

Fibular osteoseptocutaneous flap has been widely used for unilateral mandibular reconstruction. However, reports about the effects of fibular osteoseptocutaneous flap for the reconstruction of bilateral mandibular defects are limited. In this study, we used free vascularized fibular flaps to successfully manage bilateral mandibular osteoradionecrosis(ORN) in 5 patients.

[Electromyographic monitoring of facial nerve during parotid surgery].

Objective: To analyze the benefits of facial nerve electromyographic monitoring during parotid tumor surgery.

Methods: In the study, 92 patients with parotid tumor who underwent surgery were surveyed. The study group consisted of 46 patients who underwent intraoperative electromyographic monitoring, and 46 patients served as the control group.

[Surgical treatment of transected peripheral facial nerve injury].

Objective: To evaluate the results of peripheral facial nerve reconstruction by surgical treatment and determine the influence factors for recovery.

Methods: From 1999 to 2009, 104 patients underwent surgical rehabilitation for transected peripheral facial nerve injury in the department of oral and maxillofacial surgery, Peking University School and Hospital of Stomatology. The age ranged from 2 to 77 years with a median age of 30 years.

One-stage operation for noma-induced bilateral ankylosis accompanied with mouth verrucous carcinoma - a case report and review of literature.

A rare case of a male patient who suffered from noma with sequelae of ankylosis in bilateral temporomandibular joints for 52 years and a neoplasm in the right commissure of the lips for 1 year, was operated on to resolve the ankylosis, remove the neoplasm and reconstruct the soft tissue defect with a forearm flap through a one-stage operation. The neoplasm pathology was verrucous carcinoma.

Efficacy of functional training of the facial muscles for treatment of incomplete peripheral facial nerve injury.

Objective: To investigate the efficacy of functional training of facial mimic muscles for patients with incomplete peripheral facial nerve injury.

Methods: Ninety-two patients with 241 injured branches of incomplete peripheral facial nerve injury were divided into a treatment group and a control group. The treatment group consisted of 58 cases that received functional training of facial mimic muscles.

[Clinical analysis of 182 cases with facial nerve injury].

Objective: To investigate the recovery patterns and the influencing factors of facial nerve injury in maxillofacial surgery by retrospective analysis of a serial clinical data.

Methods: A total of 182 patients with facial nerve injury were reviewed. The cause of injury, the initial facial nerve function after trauma, the treatment, the initial recovery time of facial nerve function and the total recovery time were recorded.
