The case notes of 34 patients undergoing rehabilitative facial nerve surgery between 1978 and 1994 were retrospectively examined. Thirteen patients underwent facio-hypoglossal transposition with six achieving a facial nerve grade of IV (House-Brackmann scale) at 24 months post-surgery. Twelve patients underwent cable grafting of the facial nerve defect. Of these, 10 achieved a grade III result ...

OBJECTIVE The dehiscent facial nerve canal has been well documented in histopathological studies of temporal bones as well as in clinical setting. We describe clinical and radiologic features of a child with recurrent facial nerve palsy and dehiscent facial nerve canal. METHODS Retrospective chart review. RESULTS A 5-year-old male was referred to the otolaryngology clinic for evaluation of ...

OBJECTIVES/HYPOTHESIS To determine the procedure-specific incidence, risk factors, and injury patterns in patients with iatrogenic facial nerve injury as seen at a tertiary care facial nerve center. STUDY DESIGN Retrospective chart review. METHODS Facial Nerve Center patient records from 2002 to 2012 were reviewed for cases of iatrogenic facial nerve injury. These were analyzed by type of i...

Facial palsy resulting from loss of the intracranial portion of the facial nerve has been reconstructed traditionally by transferring motor axons from the hypoglossal nerve to the facial nerve.1–4 This approach can reinnervate the facial muscles if it is done before these muscles have undergone irreversible atrophy, eliminating the need for a free-muscle transfer. The two major disadvantages of...

OBJECTIVE To introduce a Thy1-GFP transgenic rat model, whose axons constitutively express green fluorescent protein (GFP), in order to study facial nerve regeneration. Facial nerve injury can cause devastating physical and social sequelae. The functional recovery of the facial nerve can result in synkinesis and permanent axonal misrouting. Facial nerve research has been hindered by the lack of...

A 61-year-old woman suffered transient mydriasis and prolonged facial nerve palsy after intracisternal papaverine application subsequent to elective clipping of an unruptured middle cerebral artery aneurysm. The mydriasis resolved within 90 minutes, but the facial nerve dysfunction persisted for 2 months before complete recovery. Prolonged irrigation of the cisterns may have washed the papaveri...

Facial nerve palsy induces a weakness or loss of facial expression through damage of the facial nerve. A quantitative and reliable assessment system for facial nerve palsy is required for both patients and clinicians. In this study, we propose a rapid and portable smartphone-based automatic diagnosis system that discriminates facial nerve palsy from normal subjects. Facial landmarks are localiz...

The author presents an unusual extension of the cerebrospinal fluid space into the proximal tympanic part of the facial nerve, and points out the clinical and surgical significance of this anatomical variation.

Muscles innervated by the facial nerve show differential sensitivities to muscle relaxants than muscles innervated by somatic nerves. The evoked electromyography (EEMG) response is also proportionally reduced after facial nerve injury. This forms the theoretical basis for proper utilization of muscle relaxants to balance EEMG monitoring and immobility under general anesthesia. (1) To observe th...

OBJECTIVES To determine the effectiveness of intraoperative facial nerve monitoring (FNM) in preventing immediate and permanent postoperative facial nerve weakness in patients undergoing primary parotidectomy. DATA SOURCES PubMed-NCBI database from 1970 to 2014. REVIEW METHODS A systematic review and meta-analysis of the literature was conducted. Acceptable studies included controlled serie...
