Summary
Brief summary (as posted)
The parotid has a close relationship with the extra temporal course of the facial nerve. The study aimed to evaluate the accuracy and safety of trident landmark during superficial parotidectomy in the identification of the facial nerve trunk.

- Superficial parotidectomy using trident landmark technique
- description
- A modified Blair incision was made along the preauricular skin crease with the same steps of the routine parotid surgery. Dissection was performed using bipolar cautery and blunt instrument; from the tragal cartilage (the anterior surface) until the bony anterior wall of the external auditory canal (EAC); from there, the dissection was done using a blunt instrument. The styloid process's base is the upper point of the trident landmark; it is the superior portion of the trident landmark. Identification of the posterior belly of the digastric muscle till its origin was performed deep to the sternocleidomastoid muscle; it is the lower point of the landmark. The facial nerve is located in the region between these two structures.
