PURPOSE The parotidectomy technique still has an elevated paresis and paralysis index, lowering patient life's quality. The correct identification of the facial nerve can prevent nerve damage. Fluorescent dye identifies nerves in experimental studies but only few articles focused its use on facial nerve study in parotidectomies. We aimed to stain the rat facial nerve with fluorescent dye to fac...

Facial nerve paralysis because of penetrating trauma through the external auditory canal is extremely rare, with a paucity of published literature. The objective of this study is to review the literature on transtympanic facial nerve paralysis and increase physician awareness of this uncommon injury through discussion of its clinical presentation, management and prognosis. We also aim to improv...

The facial nerve is the most frequently damaged nerve in head and neck trauma. Patients undergoing facial nerve reconstruction often complain about disturbing abnormal synkinetic movements of the facial muscles (mass movements, synkinesis) which are thought to result from misguided collateral branching of regenerating motor axons and reinnervation of inappropriate muscles. Here, we examined whe...

Facial nerve schwannomas involving posterior and middle fossas are quite rare. Here, we report an unusual case of cerebellopontine angle facial schwannoma that involved the middle cranial fossa, two years after the first operation. A 53-year-old woman presented with a 3-year history of a progressive left side hearing loss and 6-month history of a left facial spasm and palsy. Magnetic resonance ...

Intraparotid facial nerve neurofibromas are a rare entity, and are grossly and histopathologically distinct from the comparatively more prevalent schwannomas. We report a rare case of an intraparotid facial nerve neurofibroma with intratemporal extension in a 48-year-old female. The tumor was surgically excised with cable grafting of the facial nerve. Electroneurography may eventually assist in...

OBJECTIVE Details regarding the molecular biological features of Bell's palsy have not been widely reported in textbooks. We genetically analyzed facial muscles and clarified these points. MATERIALS AND METHODS We performed genetic analysis of facial muscle specimens from Japanese patients with severe (House-Brackmann facial nerve grading system V) and moderate (House-Brackmann facial nerve g...

Iatrogenic facial nerve injury is one of the most severe complications of cochlear implantation (CI) surgery. Intraoperative facial nerve monitoring (IFNM) is used as an adjunctive modality in a variety of neurotologic surgeries. The purpose of this retrospective study was to assess whether the use of IFNM is associated with postoperative facial nerve injury during CI surgery. The medical chart...

OBJECTIVE To explore and analyze the influencing factors of facial nerve function retainment after microsurgery resection of acoustic neurinoma. METHODS Retrospective analysis of our hospital 105 acoustic neuroma cases from October, 2006 to January 2012, in the group all patients were treated with suboccipital sigmoid sinus approach to acoustic neuroma microsurgery resection. We adopted resea...

E xtracapsular dissection with facial nerve dissection (ECD-FND) uses standard surgical landmarks to identify and antegrade dissect the facial nerve trunk at the onset of the procedure. The branches of the facial nerve are dissected up to the anterior extracapsular margin of the tumor; then, the tumor is dissected with a thin layer (1-2 mm) of parenchyma and fascia around it (Figure 1). Extraca...
