“…Of 53 full-text studies reviewed for potential inclusion; only 10 met the inclusion criteria and were assessed for reliability ( Table 1 ). The other 43 articles were excluded with reasons (8 studies included malignant tumors[ 12 , 34 – 40 ], 1 study included only one patient in RFND group[ 41 ], 1 study included revision parotidectomy[ 42 ], 1 included recurrent tumors[ 43 ] ( Table 3 , Fig 1 ), 32 studies reported either AFND or RFND technique.…”

ObjectiveThe primary aim of this meta-analysis was to test the null hypothesis of no difference in facial nerve dysfunction in studies that compared classical antegrade facial nerve dissection (AFND) versus retrograde facial nerve dissection (RFND) during benign parotid surgery.MethodsA comprehensive search of PubMed, the Cochrane Central Register of Controlled Trials, Scopus, Google Scholar, Science Direct and relevant journals was undertaken up to June 27, 2018. Randomized controlled clinical trials (RCTs), controlled clinical trials (CCTs), and retrospective studies aimed at comparing the effect of AFND vs. RFND during parotidectomy were included. The outcome measures included facial nerve dysfunction, Frey’s syndrome, recurrence, silaocele, salivary fistula, operating time length of hospital stay, and estimated blood loss. Pooled risk ratio (RR) and weighted mean differences (MD) with 95% confidence intervals were calculated using either a fixed-effects or random-effects model.ResultsTen studies; four RCTs and five retrospective studies were included. There were 570 patients (319 in RFND group and 251 in AFND group). 481 patients in 9 studies reported the incidence rate of facial nerve dysfunction. No statistical significant difference was observed between both groups concerning the occurrence of transient or permanent facial nerve paralysis (p = 0.44 and 0.11 respectively). One out 10 studies reported the incidence rate of sialocele, however no statistical difference was observed between the two techniques. There was reduction in the operative time (19.30 min), amount of blood loss (25.08 ml) and amount of healthy salivary tissues removed (12.20 mm) in RFND compared with AFND.ConclusionsAccording to the results of the current review there is no evidence demonstrating a significant advantage of one approach over another, therefore, well-designed standardized RCTs are required.

“…Sharma et al recommended the use of buccal branch of facial nerve to locate the main trunk. The reason behind was due to the regular course and adequate size of this branch of facial nerve in its peripheral area co-located with stenson's duct, which enabled it to be easily identified during surgery [11]. Pia et al [12] used orbicular branch, on account of difficulty in locating the main trunk of the nerve in 5 cases of retrograde exploration of the nerve.…”

To find out the most easily identifiable and anatomically consistent landmark for identification of facial nerve during parotid surgery. Ten cadaveric dissections and ten live parotid surgeries for different types of parotid tumours were done. Cadaveric dissection was performed in the Department of Anatomy and the surgeries were done in the Department of ENT and Head and Neck surgery of R. G. Kar Medical College of Kolkata. The distance of the facial nerve trunk from three most commonly used landmarks (viz., tympanomastoid suture, tragal pointer and posterior belly of digastric muscle) was measured in both cadaver and live patients. The ease of identification of the nerve trunk using each of the landmarks, particularly during live surgery was also assessed. The mean distance of the tympanomastoid suture from the facial nerve trunk was 3.5 mm (cadaver) and 3.87 mm (live surgery), the tragal pointer was found to be at a mean distance of 16.61 mm (cadaver) and 16.36 mm (live surgery) and in case of the posterior belly of digastric muscle it was 7.41 mm (cadaver) and 8.03 mm (live surgery). During live surgery the posterior belly of digastric was found to be the most easily identifiable landmark with a consistent anatomical relationship with the nerve trunk. The posterior belly of digastric muscle is the most easily identifiable and a very consistent landmark for facial nerve dissection during parotidectomy. When supplemented with the tragal pointer, accuracy in identifying the facial nerve trunk is very high, thereby avoiding inadvertent injury to the nerve trunk.

“…So because of the little space between the mastoid process and the cancerous parotid gland, working on this are aisextremely difficult 7 . Another example of the importance of afull identification off acial nerve is in parotid gland surgery, in which the parotidgl and iscloseto the extra-cranial region of the facialnerve 8 . generally in any parotidsurgery, the identification of the facial nerve trunk is a need.…”

Generally in any parotid surgery it is necessary to identify the trunk and branches of the facial nerve. For damage to this nerveor its branches may have irreparable consequences. The purpose of this study was to evaluate the frequency of anatomical variation of facial nerve branching in patients undergoing parotid surgery. 94 patients undergone parotid surgery in Imam Khomeini Hospital of Jondishapur Universityof Ahvaz from September 2011 to September 2014 were studied. All patients had benig nunilateral parotid surgery. During surgery and dissection, the parotid glands of the patients were photographed and the anatomy of the facial nerve and its branches in the parotidglands of patients were interpreted. The schematic picture of the anatomy of thefacial nerve within the parotidg land was drawn. The images were divided into three groups: type A, Band C. :The number of patients with a variety of nerve type A was 25, type B,47and type C,22. The comparison between the nerve and sexusing the Chi-square test showed that there is no significant relationship between gender and type of nerve (P value = 0.6). The range of the patients' age was 25-65years. In this study no newlandmark was found and of the 94 patients, 25 (26%) weretypeA, 47 (50%) type B and 22 (24%) typeC. In the parotid surgery, if the anatomical variation of facial nerve is kept in the mind, the adverse effects and damage tothe facial nerve and its branches can be avoided. More accurate and complete study of the anatomical nerve branching can benefitall types of surgery involved in the area.
