Abstract A 37-yr-old female with prior transient left facial paralysis presented with hearing loss, headaches, and resolved transient right facial paralysis. The neurological examination demonstrated normal facial movement, left hearing loss, and left vocal cord weakness. Magnetic resonance imaging demonstrated a >3 cm left paraganglioma traversing the jugular foramen. After obtaining informed consent from the patient, the tumor was embolized and then resected via a combined left postauricular infratemporal fossa and transcervical approach with cranial nerve monitoring. The ossicles were removed and the vertical segment of the facial nerve was skeletonized. The jugular bulb was identified in the hypotympanum and the petrous carotid artery was exposed. The digastric muscle was reflected inferiorly and the extratemporal facial nerve was identified. The stylomandibular ligament was transected to unlock the exposure to the infratemporal fossa. The external carotid branches were ligated. The vagus nerve and cervical sympathetic chain were infiltrated with tumor, requiring resection. The presigmoid dura and occluded jugular bulb were opened to complete the tumor resection, while preserving the medial wall. Despite anatomic preservation, the glossopharyngeal, accessory, and hypoglossal nerves were postoperatively weak and a facial paralysis recovered after 1 wk. Magnetic resonance imaging at 1 yr demonstrated a clean jugular foramen, although a thin rim of tumor remained around the petrous carotid.

Magnetic resonance imaging (MRI) has been widely used in the evaluation of suspected acoustic neuroma, but has not received the same attention with respect to facial paralysis. High-resolution computed tomography (HRCT) has been the radiologic test of choice to evaluate the facial nerve. The necessary HRCT projections, slices, and enhancement techniques to visualize each segment have been outlined. We have developed a radiologic protocol that uses MRI in conjunction with HRCT, applying the strengths of each to evaluate the facial nerve. We have evaluated 15 patients and have found that MRI is the better study to evaluate the brain stem/cerebellopontine angle segment of the facial nerve and better evaluates bone-soft tissue Interfaces. HRCT is better in the evaluation of the intratemporal segment of the facial nerve and the assessment of the anatomic perspectives of a lesion within the temporal bone. The results are discussed and case reports Illustrate the efficacy of this approach.

Background We report a case of hypertensive microbleeds strategically located at the attached segment (AS) and root entry zone (REZ) at the left facial nerve causing facial paralysis. Case Report A 60-year-old woman presented with sudden onset left facial paralysis. Medical history was significant for poorly controlled hypertension secondary to bilateral adrenal hyperplasia (primary hyperaldosteronism). The patient was initially treated for presumptive Bell’s palsy. Subsequent magnetic resonance imaging of the brain and internal auditory canal showed two microbleeds at the left cerebellopontine angle. Dedicated coronal T1 magnetization prepared rapid acquisition gradient echo and T2 sampling perfection with application optimized contrasts using different flip angle evolution sequences revealed two acute microbleeds located at the attached AS and REZ of the left facial nerve. The patient experienced only partial recovery from House–Brackmann grade IV facial paralysis at presentation to a House–Brackmann grade III facial paralysis at 1 year of follow up. Conclusions To the best of the authors’ knowledge, this is the first reported case of facial paralysis caused by microbleeds directly affecting the vulnerable AS and REZ facial nerve segments. We discuss the zonal microanatomy of the facial nerve and the crucial role of high resolution MRI for diagnosis.

Facial Function

The role of gadolinium-enhanced MRI (Gd-MRI) in the diagnosis of idiopathic facial paralysis (IFP) in children is not well defined. Fourteen children with IFP were evaluated to assess the use of Gd-MRI for the presence and pattern of enhancement and its usefulness in predicting the recovery of facial function. Six of 14 children had enhancement of the facial nerve on Gd-MRI, whereas 8 had none. Enhancement was noted in the tympanic, mastoid, and most commonly in the distal intracanalicular and labyrinthine segments. The average time from onset of paresis to recovery in patients with enhancement was 19.3 weeks, whereas in those with no enhancement, mean recovery time was 9.5 weeks ( P = 0.003, t test). All 14 patients eventually had recovery to House-Brackmann grade I or II. Gd-MRI is not required for all children with IFP but may yield information about the time course of recovery of facial function.
