Comparative StudyComparison between intraoperative observations and electromyographic monitoring data for facial nerve outcome after vestibular schwannoma surgery.
A four-channel device may enhance the sensitivity of electromyography (EMG). Determination of stimulation thresholds (STs) below 0.05 mA improves facial prognostic information after vestibular schwannoma (VS) surgery. To compare intraoperative observations with electromyographic data for predicting the immediate facial function outcome after VS surgery. ⋯ At postoperative Day 8, good facial function (Grades 1 or 2) was observed in 93% of cases for STs in the adhesion zone of 0.01-0.04 mA, 85% for STs of 0.05-0.3 mA and 79% for STs > 0.3 mA. These STs were related to the degree of tumor adhesion and not to the nerve stretch. The maximal EMG response was detected in the frontal or platysma muscles in 26% of cases, and in the orbicularis oris and orbicularis oculi muscles in 74%.

Case ReportsSudden deafness as a sign of stroke with normal diffusion-weighted brain MRI.
Sudden deafness without associated neurological signs and symptoms is typically attributed to a viral inflammation of the labyrinth. Sudden deafness as a heralding manifestation of basilar occlusion has rarely been described. A 60-year-old male with hypertension presented with an acute onset of isolated sudden deafness with vertigo. ⋯ Two days after the onset of symptoms, the patient presented with an exacerbation of vertigo. A follow-up MRI scan revealed new infarcts involving the right middle cerebellar peduncle, right dorsolateral pons and right anterior cerebellum. In this patient, the acute onset of isolated sudden deafness with vertigo may have been a heralding manifestation of the pontocerebellar infarction.

LetterEndoscopic vocal cord medialization: a new surgical technique without neck incision for laryngeal palsy.
Different types of surgery have been reported for glottal insufficiency due to unilateral vocal cord paralysis. We recently developed a new surgical technique of fascia implantation known as vocal cord medialization. ⋯ This new technique is described in detail herein, together with the satisfactory results we obtained in six cases of unilateral vocal cord paralysis with a wide glottal gap during phonation. We recommend this technique in cases of unilateral vocal cord paralysis in which both a satisfactory clinical result and an aesthetically pleasing cosmetic result are required.
