Middle Ear Salivary Choristoma: A Rare Case Report and Update on Congenital Associations, Facial Nerve Involvement, and Treatment Strategies

Table 2

Facial nerve involvement.

Facial nerve	Total	Complete excision	Biopsy/partial excision	value
Involved	18	8 (44.4%)	10 (55.6%)	0.0027
Not involved	19	16 (84.2%)	1 (5.2%)	—

Complete excision vs. biopsy/partial excision has different risks to the facial nerve. Two cases that had no facial nerve involvement and did not specify the exact procedure may underestimate the risk of facial nerve involvement during complete excision.
