Abstract

This study aims at finding different branching patterns of facial nerve during parotid surgeries and the relationship of the nerve to tragal pointer (TP) and stylomastoidforamen (SMF). The facial nerve enters the body of the parotid gland with varying branching patterns, establishing unique relationship requiring close care while doing parotidectomies. A Hospital Based Prospective Observational, descriptive study, conducted among the participants in a tertiary care centre for a period of 18 months who underwent superficial parotidectomy. In the present study 50% patients had type 2 branching pattern, 24% patients had type 3 branching pattern, 15% had type 4 branching pattern and 10% had type 1 branching pattern. Mean Distance between main trunk and tragal pointer is 7.5 mm and standard deviation is 1.5. Mean Distance between main facial nerve trunk (FNT) and stylomastoid foramen is 1.54 mm and standard deviation is 0.2. Type 2 is the commonest branching pattern of facial nerve inside the parotid gland. This study will provide a road map for the surgeons to anticipate the variations in branching patterns and the knowledge of result of our study might help in decreasing the iatrogenic injury of facial nerve during parotid surgeries.

腮腺切除术中面神经的多种分支模式——解读腮腺上面神经的神秘路线。

本研究旨在探讨腮腺手术中面神经的不同分支形态，以及面神经与侧指（TP）和茎突乳突孔（SMF）的关系。面神经以不同的分支方式进入腮腺体内，建立了独特的关系，需要在腮腺切除术时密切注意。一项基于医院的前瞻性观察性描述性研究，在三级护理中心进行了为期18个月的腮腺浅表切除术的参与者中进行。2型支型占50%，3型支型占24%，4型支型占15%，1型支型占10%。主干道与十字指针的平均距离为7.5 mm，标准差为1.5。面神经主干距茎突孔的平均距离为1.54 mm，标准差为0.2。2型是腮腺内最常见的面神经分支类型。本研究将为外科医生预测腮腺分支模式的变化提供一个路线图，我们的研究结果可能有助于减少腮腺手术中面神经的医源性损伤。

期刊介绍： Indian Journal of Otolaryngology and Head & Neck Surgery was founded as Indian Journal of Otolaryngology in 1949 as a scientific Journal published by the Association of Otolaryngologists of India and was later rechristened as IJOHNS to incorporate the changes and progress. IJOHNS, undoubtedly one of the oldest Journals in India, is the official publication of the Association of Otolaryngologists of India and is about to publish it is 67th Volume in 2015. The Journal published quarterly accepts articles in general Oto-Rhino-Laryngology and various subspecialities such as Otology, Rhinology, Laryngology and Phonosurgery, Neurotology, Head and Neck Surgery etc. The Journal acts as a window to showcase and project the clinical and research work done by Otolaryngologists community in India and around the world. It is a continued source of useful clinical information with peer review by eminent Otolaryngologists of repute in their respective fields. The Journal accepts articles pertaining to clinical reports, Clinical studies, Research articles in basic and applied Otolaryngology, short Communications, Clinical records reporting unusual presentations or lesions and new surgical techniques. The journal acts as a catalyst and mirrors the Indian Otolaryngologist’s active interests and pursuits. The Journal also invites articles from senior and experienced authors on interesting topics in Otolaryngology and allied sciences from all over the world. The print version is distributed free to about 4000 members of Association of Otolaryngologists of India and the e-Journal shortly going to make its appearance on the Springer Board can be accessed by all the members. Association of Otolaryngologists of India and M/s Springer India group have come together to co-publish IJOHNS from January 2007 and this bondage is going to provide an impetus to the Journal in terms of international presence and global exposure.
