Facial nerve palsy due to temporal bone metastasis of hepatocellular carcinoma (HCC) has rarely been reported. We experienced a rare case of temporal bone metastasis of HCC that initially presented as facial nerve palsy and was diagnosed by surgical biopsy. This patient also discovered for the first time that he had chronic hepatitis B and C infections due to this facial nerve palsy. Radiation ...

OBJECTIVES/HYPOTHESIS To evaluate a transcanal approach for placement of a stimulating electrode array in the cochlear nerve. STUDY DESIGN Prospective cadaveric temporal bone study. METHODS Ten human cadaveric temporal bones were dissected. Both a facial recess approach with mastoidectomy and a transcanal approach using the novel technique were performed in each bone. A middle fossa dissect...

PURPOSE To investigate the correlation between gadolinium enhanced magnetic resonance image (MRI) results and surgical findings of facial nerves in Bell's palsy and Ramsay Hunt syndrome. MATERIALS AND METHODS From 1995 to 2004, MRI was performed on 13 patients with Bell's palsy or Ramsay Hunt syndrome, who were offered with surgical decompression of the facial nerve through the middle cranial...

BACKGROUND AND PURPOSE The imaging appearance of facial nerve schwannomas (FNSs) has been described as an enhancing tubular mass (using T1-enhanced MR) within an enlarged facial nerve canal (using CT). The purpose of this study is to identify how often the FNS imaging findings conform to this description and determine whether there are underlying anatomic explanations for the discrepant imaging...

BACKGROUND Two-stage facial reanimation procedures with a cross-facial nerve graft often have unsatisfactory results in the older patient. Although the cause of result variability is likely multifactorial, some studies suggest that increased donor nerve axonal load improves function of a free muscle transfer after a cross-facial nerve graft. This study attempts to characterize the relationship ...

BACKGROUND Marginal mandibular nerve injuries are more likely to be symptomatic than other facial nerve injuries following facelift procedures. The marginal mandibular nerve courses over the facial artery in the region of the mandible. The nerve is most susceptible to injury in this location because it lies superficial to the anterior facial artery. OBJECTIVES The authors describe the locatio...

In this study we evaluate the postoperative facial nerve function after vestibular schwannoma (VS) surgery and analyze the factors that cause it. We included 97 consecutive patients undergoing surgical excision of sporadic unilateral VS. Patient and tumor characteristics, surgical approaches, facial nerve function, extent of tumor removal, perioperative complications are all analyzed through st...

Facial nerve tumors are a very uncommon neoplasm. They may originate from any segment of the VIIth nerve, from the cerebellopontine angle to the peripheral branch in the parotid gland. Because of lack of specific clinical symptoms, diagnosis may be difficult. Small facial tumors may also remain asymptomatic and only be discovered incidentally. Reports of tumor excision in which the nerve is lef...

Facial nerve schwannomas (FNS) are encapsulated benign tumors arising from Schwann cells of seventh cranial nerve. Most of the facial nerve schwannomas are localized in intratemporal region; only 9% of cases involve a portion of the extratemporal segment. Preoperative diagnosis is often unclear; diagnosis is often made intraoperatively. Management of intraparotid FNS is troublesome because of t...
