“…There were no statistical differences between the genders in keeping with previous studies. 10,31 The longest length were from USA (21 mm) and India (18.5 mm); in contrast, another study in USA reported the shortest length (9.38 mm). 28,33,34 The length of FN in our population was greater by 1 mm from the average identical to the study from Israel and India.…”

“…Several authors have reported the possibilities of trifurcation, quadrifurcation, or even a plexiform branching pattern of the FN trunk 2,5, 13,15,20,23,30 -7,9,15,19,20,30 Trifurcation in the present study was observed in 20% of the population like other studies from Turkey reporting trifurcation of 18.6, 18.8, and 18%, respectively. 6,31,32 Khaliq et al in another study from Indian reported single trunk of FN in 95 and 8.57% of bifurcation, while Rana et al reported single trunk (2%) and trifurcation (3%). 18,19 With regard to furcation of the main trunk, 14 were similar, while 6 were not (►Table 4).…”

“…The results from this study tally with Kopuz et al and Kalaycioğlu et al on bilateral configurations. 6,31 Previous studies had not attempted to correlate the bilateral configuration. This could be of surgical relevance in case of bilateral surgical procedures to predict the opposite side configurations.…”

There are known racial variations in the branching and furcation pattern and the length of the facial nerve (FN) trunk and hardly any studies from the black African population. Surgeries around the FN predispose it to trauma and warrant a detailed anatomy of its branching pattern. Using a descriptive cross-sectional study, a total of 40 FN (20 fresh cadavers) were dissected to record the pattern and length of the FN. The frequency of various patterns of FN using the Davis et al classification was as follows: type I: 10 (25%), type II: 9 (22.5%), type III: 7 (17.5%), type IV: 6 (15%), type V: 2 (5%), and type VI: 6 (15%). The nerve bifurcated in 32(80%) and trifurcated in 8(20%) of the cadavers. There was no statistical difference in the branching patterns ( p = 0.509) and furcation types ( p = 0.414) between the sides and gender. The length of the trunk of the FN measured from the stylomastoid foramen to the bifurcation point was 16.14(−/+ 3.28 mm). The results from this data established a variation in the anatomical branching pattern of the FN in a black Kenyan population.

“…The present study is based on cadaver dissection and joins a large body of literature describing attempts to evaluate the various surgical landmarks of the FN using cadavers (Holt, ; Rather and Osman, ; Bushey et al, ; Kalaycioglu et al, ). We dissected 38 adult necks (of which 22 were male, and 16 were female, their ages ranging between 77 and 91 years), such that a total of 75 heminecks were dissected (one of the heminecks was omitted from our study, due to a large hematoma making dissection very difficult).…”

A new method for tracing the facial nerve trunk using the posterior auricular nerve

Tracing the facial nerve trunk is an essential action in parotid surgery, because of the implications of injury to the nerve or its branches. More than a few landmarks that may help the surgeon in this task have been proposed (e.g., the posterior belly of the digastric muscle, the tragal pointer, among others), under the assumption that additional access methods improve the surgical technique and reduce the possibility of harmful post-operative consequences. Here we present evidence that the posterior auricular nerve may be used to trace the facial nerve trunk. We dissected 75 cadaveric heminecks, exposed the auricularis posterior muscle and adnexa, and attempted to follow the posterior auricular nerve to the facial nerve trunk. The auricularis posterior muscle, nerve, and artery were identified in all heminecks, securing an anatomically reliable route to the facial nerve trunk. Average length of the nerve from the auricularis posterior muscle to the facial nerve trunk was 28 mm (AE6.2 mm). The angle between the posterior auricular nerve and the vertical segment of the FN trunk was 39.5 (AE7.7 ). We conclude that the posterior auricular nerve may be used as a landmark to trace the facial nerve trunk. It is advantageous due to the relatively simple and consistent regional anatomy, and also because manipulation of this nerve does not present a risk given that the auricularis posterior muscle is vestigial. The proposed landmark is particularly important in revision surgery, where the pre-auricular anatomy may have been distorted and scarred by previous operations. Clin. Anat. 32:453-457, 2019.
