Purpose: This paper describes a new surgical procedure with electrical stimulation of the facial nerve for unresolved Bell's palsy and compares the facial nerve recovery with another group who underwent traditional middle cranial fossa decompression.
Recent Findings: All patients with total unilateral facial paralysis had surgery by the senior author 3 months from onset of Bell's Palsy. Surgical decompression was performed in 13 patients between 1992-2012 (Group 1). Surgical exposure with intraoperative electrical stimulation of the facial nerve in the peri-geniculate region was performed in 47 patients between 2012-2022 (Group 2). The facial recovery at 1 month and 3 month were significantly better in Group 2. The degree of synkinesis was significantly less in Group 2. The trans-mastoid electrical stimulation of the facial nerve is less invasive, requires no hospital stay, and less time off work compared to the middle cranial fossa approach. The earlier facial movement at one month results in less long-term unwanted faulty regeneration or synkinesis.

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.

Ultra-high-resolution CT of the temporal bone before cochlear implantation for pre-operative prediction of chorda tympani nerve management and round window access.

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.
