Centripetal approach to the facial nerve in parotid surgery: personal experience.

چکیده
There is particular interest in parotid surgery on account of the close relationship between the gland and the extrapetrous facial nerve. The seventh cranial nerve is generally located by means of an anterograde or proximal surgical identification technique aimed at identifying the facial nerve at its point of exit from the stylomastoid canal. There are very few reports in the literature on retrograde or centripetal identification techniques, which may be adapted to the morphology of the neoformation limiting surgical access, in order to isolate the nerve from its peripheral rami. The present report deals with personal clinical experience, describing a technique for retrograde detection of the facial nerve. Between 1990 and 2001, 313 parotid surgery procedures were performed at the ORL Clinic of the Università del Piemonte Orientale in Novara. In 308/313 cases, corresponding to 98% of the operations, the technique chosen for the identification of the extrapetrous facial nerve was anterograde, proximal or centrifugal; in 5 cases alone, retrograde or centripetal exploration of the orbicular branch was undertaken, on account of difficulty in locating the main trunk, due to the presence of a post-inflammatory fibrosis in three patients and a stylomastoid emergency, arising from a malignant neoformation, in the other two. The decision to resort to the identification of the orbicular nerve of the eye is supported by the regular course and adequate size of this facial branch in its peripheral area, which enable it to be easily located.
