[Significance of preserving the posterior branch of the great auricular nerve in parotid surgery].

Objective: To investigate the feasibility, technique and significance of preserving the posterior branch of the great auricular nerve in parotid surgery.

Methods: 48 cases with parotid tumor who underwent regular parotid surgery with cosmetic incision were included. The sensory testing was carried out in upper auricle, lobule, infra-auricular, pre-auricular and post-auricular region preoperatively and at 10 days, 1 month, 6 months and 12 months after operation.

[Endoscope-assisted repair of zygomatic arch fracture via a short hidden preauricular incision].

Objective: To investigate the relevant applied technique and clinical value of endoscope-assisted repair of zygomatic arch fracture via a short hidden preauricular incision.

Methods: There were 7 cases of unilateral zygomatic arch fracture and 10 cases of unilateral zygomatic fracture. Reduction and fixation of zygomatic arch in all cases were performed via a short preauricular incision assisted by endoscope.

[Observe the dissection of the tunnels of augmentation rhinoplasty under endoscope].

Objective: To observe and analyse the dissection of the tunnels in traditional blind operation of augmentation rhinoplasty.

Methods: 11 Cases of augmentation rhinoplasty were collected and be observed by an endoscope as soon as the tunnels were formed during the operations.

Results: (1) Some of the tunnels did not go through one layer.

[The value of endoscopic technique in maxillofacial and neck regions].

Objective: To discuss the value of endoscopic technique in maxillofacial and neck regions.

Methods: This retrospective review included 102 clinical patients with superficial masses in maxillofacial and neck regions. The indications, incisions, endoscopic space preparation and the key points of operative process were analysed.

[Endoscope-assisted parotidectomy for benign tumors via a short hidden auricular incision].

Objective: To evaluate a technique of endoscope-assisted parotidectomy for benign tumor via a short hidden auricular incision.

Methods: Twenty-six volunteer patients were selected for the new approach, 16 with mixed tumor, 9 Warthin's tumor and 1 lymphoepithelial cyst. The tumor size was 1.

[Minimally invasive technique of parotidectomy for benign parotid tumors].

Objective: To evaluate a minimally invasive technique of parotidectomy in treatment of benign parotid tumors.

Methods: This retrospective review included 49 patients with benign parotid gland tumors. The modified technique included incision, flap elevation, facial nerve dissection, the great auricular nerve preservation and postoperative disposal.

[Using ultrasonically activated scalpels as major instrument for vessel dividing and bleeding control in minimally invasive video-assisted thyroidectomy].

Objective: To establish new techniques on the control of vessel dividing and bleeding in minimally invasive video-assisted thyroid surgeries.

Methods: One hundred and seventy volunteer patients with nodular goiter, adenoma and Graves' disease consecutively received the endoscopic thyroid operation according to Miccoli's mode from April 2002 to June 2003. The approach was designed to use ultrasonically activated scalpels [Harmonic Scalpel (R), Johnson & Johnson, USA] as a major, suction-dissector or others as supplementary instruments during the whole process.
