In 19 rabbits, lower branches of facial nerve were experimentally sectioned and sutured to its middle branches to form a 'side to end' pattern with 2 to 3 epineural sutures. Morphological investigation showed that regenerating axons of the middle branch penetrate into the sutured trunk and grow further. The technique was applied in 7 patients. Full functional recovery was evidenced in 4 of them. The technique is recommended for clinical routine.

Background: Traumatic intracranial aneurysms (TICAs) can be fatal if ruptured. We report a case of a TICA, distant from facial bone fractures, successfully treated with flow diverter (FD) before rupture.
Case Presentation: A 20-year-old woman was admitted following a car accident.

Objective: Intraoperative systems for monitoring facial nerve function, in which temporal electrical stimulation is applied to the facial nerve through electrodes, are used in many surgeries requiring facial nerve preservation; however, continuous stimulation or quantitative evaluation of facial nerve function is difficult with this approach. We examined the usefulness of a continuous and quantitative facial nerve-monitoring system for temporal bone lesions by using our experience to modify the existing methods used for cases involving vestibular schwannomas.
Study Design: Retrospective observational study.
Ultra-high-resolution CT of the temporal bone before cochlear implantation for pre-operative prediction of chorda tympani nerve management and round window access.

Guilloz Imaging Department, Central Hospital, University Hospital Center of Nancy, Nancy, 54000, France.
Background And Purpose: To evaluate various anatomical parameters and their relationship to chorda tympani nerve (CTN) injury and round window (RW) access during cochlear implantation.
Materials And Methods: Ultra-high-resolution CT images of 66 patients were retrospectively reviewed and compared with operative reports. The facial recess and the round window were analyzed, mainly using the chorda-facial angle (CFA), the width of the facial recess, the CTN-tympanic annulus distance, the RW-mastoid portion of the facial nerve angle, and the type of RW.

An 80-year-old lady had a history of progressive swallowing difficulty over several years with significant weight loss, but prior investigations in several medical departments proved negative. Neurological assessment noted her complaint of impaired feeling for food in her mouth and examination showed impaired corneal reflexes and facial sensory function. Blink reflex electrodiagnostic testing was consistent with a diagnosis of facial onset sensory and motor neuronopathy (FOSMN).

Trigeminal neuralgia (TN) is an excruciating neurological disorder characterized by intense, stimulus-induced, and transient facial stabbing pain. The classification of TN has changed as a result of new discoveries in the last decade regarding its symptomatology, pathogenesis, and management. Because different types of facial pain have different clinical therapy and neuroimaging interpretations, a precise diagnosis is essential.
