Evaluation of Two Facial Nerve Landmarks Frequency in Parotidectomy
نویسندگان
چکیده مقاله:
Background & Aim: Various landmarks are discussed to find the facial nerve during parotid surgery. The surgeon should use existing landmarks for a safe surgical use. To evaluate two new landmarks in parotid surgery, this study was done. Methods & Materials/Patients: This cross-sectional study was conducted on 43 patients with parotid masses, whom were referred to Alzahra and Kashani tertiary hospitals in 2013. In a parotid surgery, the greater auricular nerve was detected; then the greater auricular nerve and facial nerve diameter were measured by the compass with precision of 0.1 millimeter and recorded. After facial nerve exploration, if the other landmarks of vascular and tail signs are detected, they are recorded in the files. Results: This study contained 43 patients, 22 men and 21 women. There were 21 (48.8%) masses in deep lobes and others on superficial lobes. In 36 cases (83.7%), vascular signs were observed. In 23 cases (53.5%), tail signs were found. The diameter of facial nerve was 2.647(±4641) mm (minimum: 2 mm and maximum: 4 mm). The diameter of greater auricular nerve was 2.691(±4545) mm (minimum: 2 mm and maximum: 4 mm). By paired T-test, there was no significant difference between the diameter of facial and greater auricular nerves. Of all cases, 76.7% had differences less than 0.5 mm. Conclusion: This study showed that greater auricular nerve can be used as a proper graft for facial nerve, and we can use “vascular sign” as a good indicator of facial nerve.

Facial Nerve Monitoring During Parotidectomy: A Two-Center Retrospective Study
Introduction: We present a retrospective two-center study series and discussion of the current literature to assess the benefits of facial nerve monitoring during parotidectomy. Materials and Methods: From 2007 to 2012, 128 parotidectomies were performed in 125 patients. Of these, 47 procedures were performed without facial nerve monitoring (group 1) and 81 with facial nerve monitoring (group 2...

Introduction: Malignant tumors of the parotid gland account scarcely for 5% of all head and neck tumors. Most of these neoplasms have a high tendency for recurrence, local infiltration, perineural extension, and metastasis. Although uncommon, these malignant tumors require complex surgical treatment sometimes involving a total parotidectomy including a complete facial nerve resection. Severe fu...
