Facial nerve blocks were produced in four monkeys by insertion of a needle into the facial nerve trunk. The sequential changes of nerve cells in the facial nucleus were investigated 4 days, and 2 and 7 months later. Although the facial paralysis recovered in 2 months, considerable changes of cell bodies in the facial nucleus were still obvious which recovered completely only after 7 months. It ...

Imaging plays a critical role in the evaluation of a number of facial nerve disorders. The facial nerve has a complex anatomical course; thus, a thorough understanding of the course of the facial nerve is essential to localize the sites of pathology. Facial nerve dysfunction can occur from a variety of causes, which can often be identified on imaging. Computed tomography and magnetic resonance ...

BACKGROUND Recent studies have examined the effects of brief electrical stimulation (BES) on nerve regeneration, with some suggesting that BES accelerates facial nerve recovery. However, the facial nerve outcome measurement in these studies has not been precise or accurate. Furthermore, no previous studies have been able to demonstrate the effect of BES on synkinesis. The objective of this stud...

Objectives: 1.To evaluate role of facial nerve monitoring in mastoid surgeries. 2. To define the cutoff limit for electrical dehiscence of facial nerve. Methodology: 60 patients of chronic otitis media undergoing mastoid surgery were divided into 30 each for intra-operative facial nerve monitoring (group A) and those without monitoring (group B). Minimum level of current strength for stimulatio...

OBJECTIVE To validate the Synkinesis Assessment Questionnaire (SAQ), a newly developed patient-graded instrument to evaluate facial synkinesis. STUDY DESIGN This was a prospective clinical questionnaire validation study. METHODS A total of 65 patients with facial nerve disorders were recruited from the Facial Nerve Center. In 28 patients (group I), the SAQ, a preliminary 10-item instrument,...

Numerous anomalies and variations of facial nerve anatomy leading to iatrogenic injury are described. However, there are no reports of facial nerve dehiscence near its second genu causing a hump and obstructing middle ear ventilation pathway, as found in our case. This particular anomaly of facial nerve is being reported to highlight its uniqueness and that a dehiscent facial nerve may be a rar...

Schwannomas are uncommon in the facial nerve and account for less than 1% of tumors of temporal bone. They can involve one or more than one segment of the facial nerve. The clinical presentations and the imaging appearances of facial nerve schwannomas are influenced by the topographical anatomy of the facial nerve and vary according to the segment(s) they involve. This pictorial essay illustrat...

UNLABELLED Promoting facial nerve regeneration is a significant challenge. AIM To evaluate the possible neurotrophic influence of cyclic AMP on facial nerve regeneration of Wistar rats. METHOD The right facial nerve of thirty-two animals were completely transected and immediately sutured, followed by exposure or not to topical cyclic AMP. Behavioral and histometric analyses were done at 14 ...

A forty-one-year-old man presented with right-sided progressive facial nerve paralysis of one year duration. Computed tomography of the temporal bone showed a soft tissue mass in relation with the tympanic segment of the facial nerve with destructive changes in the facial recess region. Magnetic resonance images before and after gadolinium injection revealed a contrast-enhancing mass lesion in ...
