Branching pattern of facial nerve as seen in parotidectomy
Journal Title: MedPulse -International Medical Journal - Year 2016, Vol 3, Issue 8
Abstract
Background: This study examines the types of branching patterns of facial nerve during parotid gland surgery as classified by Davis (1956), incidence of each type of branching in parotid surgeries and length of main trunk of facial nerve and its distance from tympanomastoid suture. The study was conducted on a total of 20 patients who were admitted in the department of ENT, GMC, Jammu. The most common type of branching pattern in our study was type I (45% ), followed by type III (30%), type II (10%), type IV (10%), type VI (5%) while none had the type V pattern. 13 patients out of 20 had 16-20mm length of the main trunk of facial nerve. 6 had the length of 11-15mm, one case had length greater than 20mm while none had the main trunk less than 10mm. 55% cases had a distance of 2.5 – 3mm while only 10% had the distance of >3.5mm between the facial nerve and the tympanomastoid suture. It was observed that all the cases had the Marginal mandibular nerve running below the inferior border of mandible and in 60% of the cases it was 1-1.5cm below while in 30% it was 1.6-2cm running below the inferior border of mandible. In view of the above findings, in the parotid surgery if the branching variations, variations in length of main trunk, distance of the nerve from tympanomastoid suture are kept in mind, the surgeon will be safe from unpleasant surprises.
