Development of the facial nerve was studied in normal chicken embryos and after surgical disruption of ingrowing sensory facial nerve fibers at 38-72 h of incubation. Disruption of facial nerve fibers by otocyst removal often induced a rostral deviation of the facial nerve and ganglion to the level of the trigeminal ganglion. Cell bodies of the geniculate ganglion trailed their deviating neurit...

objective: to evaluate sensorimotor nerve damage in patients with maxillofacial trauma referring to taleghani hospital, tehran, iran methods: this cross-sectional study was conducted during a 2-year period from 2014 to 2012 in taleghani hospital of tehran. we included a total number of 495 patients with maxillofacial trauma referring to our center during the study period. the demographic inform...

OBJECTIVE To review our experience with branchial cleft anomalies, with special attention to their subtypes and anatomical relationship to the facial nerve. STUDY DESIGN Case series. SETTING Tertiary care center. PATIENTS Ten patients who underwent resection for anomalies of the first branchial cleft, with at least 1 year of follow-up, were included in the study. The data from all cases w...

Facial nerve schwannomas are rare conditions which can mimic many other conditions. A series of patients with facial nerve schwannomas were treated in our department, all of whom had a delay in diagnosis resulting in a significant morbidity. This prompted us to present this rare case series of schwannomas along different segments of facial nerve and also review the literature on such tumors—the...

BACKGROUND Absolute ethanol sclerotherapy provides a reliable treatment for facial venous malformation, although facial nerve injury may occur after sclerotherapy. This study is a retrospective review of facial nerve dysfunction after sclerotherapy. METHODS A total of 91 patients with facial venous malformations accepted 288 ethanol sclerotherapy sessions. The facial nerve dysfunctions caused...

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...

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...
