Surgical Anatomy of the Facial Nerve and Parotid Gland Based upon a Study of 350 Cervico-facial Halves

Facial nerve branching pattern as seen in parotidectomy in Kashmiri population: our experience

“…Proper informed consent was taken from all patients included in this study. Facial nerve branching pattern types in parotid tissue were distributed in six types in accordance with classification of Davis et al 1 In our study we found type I pattern most common followed by type III pattern (peripheral branching pattern) of facial nerve and type VI least pattern as shown in Table 1. We also found that main trunk of facial nerve of exiting from stylomastoid foramen sometimes divides in two braches before diving in peripheral branching pattern as described in Table 1 and Table 2.…”

“…Facial nerve branching pattern is not uniform as shown by the studies conducted by various authors. [1][2][3][4][5][6][7][8] Branching patterns of the facial nerve in 20 cases were classified into six types based on the description given by Davis as follows. Patients with pre-operative facial nerve palsy/paresis, tumor fixation to overlying skin, recurrent tumor or with lymph node involvement were excluded from the study.…”

An anatomical study on the facial nerve trunk in fetus cadavers

“…A study published in 1956 investigated 350 specimens and reported on the bifurcation of the main facial nerve trunk (18). Park and Lee examined 111 facial nerves and determined a pattern of trifurcation of the main facial nerve trunk in 4.4% of cases (19).…”

Quantitative analysis of the terminal branches of facial nerve in fresh frozen head and neck specimens

“…Tzafetta and Terzis [19] made 10 fresh cadaveric hemifacial dissections and demonstrated great variability in branching pattern of the facial nerve and innervation of the mimetic muscles by facial nerve. Davis et al [3] studied the branching patterns of facial nerve and described 6 different patterns in 350 hemifacial dissections. The most common type was a single connection between the frontozygomatic and cervicofacial divisions, with a connecting loop between the zygomatic and buccal branches.…”
