title: [Dynamics of lagophthalmos depending on facial nerve repair and its intraoperative monitoring in neurosurgical patients].
abstract: Over 200 patients with acoustic neuromas and over 100 patients with posterior cranial fossa meningiomas are annually operated on at the N.N. Burdenko Neurosurgical Institute. Intraoperative monitoring of the facial nerve function is used in most patients with tumors of the posterior cranial fossa to identify the facial nerve in the surgical wound. If the anatomical integrity of the facial nerve in the cranial cavity cannot be retained, facial nerve repair is performed to restore the facial muscle function. Intraoperative electrical stimulation of the facial nerve has a great prognostic significance to evaluate the dynamics of lagophthalmos in the late postoperative period and to select the proper method for lagophthalmos correction. When the facial nerve was reinnervated by the descending branch or trunk of the hypoglossal nerve, sufficient eyelid closure was observed only in 3 patients out of 17.
