Abstract

Objective: to determine the mean distance of the main trunk of the facial nerve from two commonly employed surgical landmarks (tragal pointer and tympanomastoid suture line) among a sample of Filipino adults undergoing parotidectomy.

 

Methods

Study Design:            Prospective Descriptive Study

Setting:                       Tertiary Government Training Hospital

Subjects:                    22 patients without facial paralysis undergoing surgery for parotid neoplasms were evaluated intraoperatively.

 

Results: The main trunk of the facial nerve was found to be 9.0mm (standard deviation of 2.8mm) from the tragal pointer and 6.1mm (standard deviation of 2.0mm) from the tympanomastoid suture line.

 

Conclusion:  The mean distance from the main trunk of the facial nerve to two of the most commonly utilized landmarks in identification of the nerve during parotidectomy was 9.0mm (standard deviation of 2.8mm) from the tragal pointer and 6.1mm (standard deviation of 2.0mm) from the tympanomastoid suture line. These may serve as reference values for surgeons in safer identification and preservation of the facial nerve during parotidectomy.
