Drawing showing the anatomical landmarks, the reference triangle, and the location of the facial nerve. Arch Surg. A 3-cm skin incision was made in the center of the triangle formed by the temporomandibular joint, the mastoid process, and the angle of the mandible, and dissection was continued deep until the main facial nerve trunk was identified. The distance between the predicted and actual position of the facial nerve was measured. The mean distance between the predicted and the actual position of the nerve was 1. Reasonable speed and safety in identifying and preserving important anatomical structures are of vital importance for successful surgery in all specialties.
A Simple Method for Safe Identification of the Facial Nerve Using Palpable Landmarks
Easy and Safe Method for Facial Nerve Identification in Parotid Surgery
The facial nerve forms the center point between the base of the styloid process and the origin of the posterior belly of the digastric muscle. Anatomy was initially studied in two cadavers. Then the images of temporal styloid regions were studied for consistency of the presence of the styloid base. In the second part of the radiologic study, the distance between the styloid base and the origin of the posterior belly of the digastric muscle was studied in 50 parotid regions. The clinical study involved 25 patients who underwent parotidectomy.
Identification of Facial Nerve During Parotidectomy: A Combined Anatomical & Surgical Study
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. Kar Medical College of Kolkata. The distance of the facial nerve trunk from three most commonly used landmarks viz.
Correspondence Address : Dr. Background: Preserving the integrity of the facial nerve during parotid surgery depends on its exposure, and this requires a detailed knowledge of its anatomy by the operating surgeon. For easy identification of the facial nerve, a number of landmarks have been described.
