Facial paresis as a sign or symptom is caused by a number of different conditions. Although being the most common type of facial paresis, Bell's palsy represents a diagnosis of exclusion characterized by an acute, unilateral peripheral facial palsy of unknown etiology. Clinical features and laboratory findings are considered with regard to their diagnostic as well as prognostic significance.

Three cases of bilateral deafness with cytologically-demonstrated meningeal carcinomatosis are reported. The first patient, a 64-year old man, presented with bilateral deafness, gait disturbances, and bilateral facial paresis. The second patient, a 78-year-old man, had bilateral deafness, unsteady gait and fluctuations in consciousness. The last patient, a 69-year-old man, complained of bilateral deafness and severe headache, and presented with right facial paresis and left laterodeviation while walking. All three patients had abnormal cochleo-vestibular findings and brainstem auditory evoked responses (BAER) that suggested peripheral lesions with absent or very delayed I waves. The brain CT scans with an without contrast enhancement were entirely normal, and the diagnosis was established by lumbar puncture. From our own cases and a review of the literature, deafness in meningeal carcinomatosis may start unilaterally but becomes bilateral in less than a week. Vestibular disturbances may not be apparent, but they can be demonstrated in almost all cases. Facial paresis or plegia is also a very frequent finding. The destruction of the eighth and seventh cranial nerves is probably due to direct infiltration by neoplastic cells as well as to ischemia through compression of the nerve supplying vessels. The 3 cases presented here emphasize once again the important fact that meningeal carcinomatosis remains a cytological diagnosis, several lumbar punctures being sometimes necessary, and that cerebrospinal fluid studies cannot yet be supplanted by other diagnostic techniques like contrast-enhanced CT or MRI with gadolinium.

A 64-year-old man with right aural discharge presented complaining of progressive deafness. Other otological symptoms were absent and specifically there was no seventh nerve paresis. A right aural polyp was identified and biopsied. Histology showed the polyp to be a schwannoma. Subsequent temporal bone computed tomography showed expansion of the distal facial canal. At operation, the schwannoma filled the middle ear cleft and extended from the genu to the region of the stylomastoid foramen. The floor of the middle ear had been eroded, exposing the jugular bulb. Facial paresis is the usual presenting feature of a facial schwannoma, while deafness, ageusia and reduced lacrimation are variable, dependent upon the site of the lesion. The absence of facial palsy as a presenting feature is very rare and this case illustrates the need for histological examination of all abnormal aural material.

Facial paresis and low frequency hearing loss was observed 16 days after spinal anaesthesia in a 22 years old male patient. Both disturbances disappeared within a short time of bed rest as the only therapy. The hearing loss showed the typical picture which we have observed in the last few years as a complication of spinal anaesthesia. The facial paresis which appeared at the same time could well be caused by low of cerebrospinal fluid pressure due to leakage via the puncture hole.

Facial paresis is the only clinical symptom of two deep-seated, moderately malignant salivary duct carcinomas. The unusual course of the pareses (recurrences, varying degrees of severity) prompts the diagnosis of Bell's palsy. The final, exact diagnosis of a epithelial-myoepithelial intercalated duct carcinoma, respectively of a polymorphic low-grade adenocarcinoma, is made as late as six, respectively three, years after onset of the paresis.

This retrospective study concerns benign parotid gland tumors in 306 Japanese patients who were treated by partial parotidectomy with preservation of the facial nerve. There were no recurrences in 112 with a pleomorphic adenoma in over a 5-year follow-up. Facial weakness and temporal paresis occurred in 18% of 232 patients and Frey's syndrome in 18% of 93 with longer than a 3-year follow-up. In comparison with reported results of lateral or superficial parotidectomy, partial parotidectomy with preservation of the facial nerve seems preferable for treatment of patients with a benign parotid gland tumor.

Twenty-nine patients, aged 11-79 years (mean, 50 years), with Lyme neuroborreliosis, facial nerve palsy, and meningitis were treated with oral doxycycline (daily dose, 200-400 mg) for 9-17 days in a prospective, nonrandomized study. Facial paresis was bilateral in eight (28%) of the 29 patients. Twenty-six patients (90%) recovered without sequelae within 6 months, while three of the patients with bilateral facial palsy at admission had remaining paresis at follow-up. In five patients, contralateral facial paresis developed 1-12 days after initiation of therapy, and two patients were retreated with antibiotics. Posttreatment examinations of cerebrospinal fluid showed a marked decrease of inflammatory cells and protein concentrations compared with pretreatment levels in all followed up patients. The favorable clinical outcome agrees with findings of other reports on intravenous antibiotic therapy for Lyme disease-associated meningitis with facial palsy. Our conclusion is that oral doxycycline is an effective and convenient therapy for Lyme disease-associated facial palsy.

Mutations in the dynamin-2 (DNM2) gene can cause autosomal dominant or sporadic centronuclear myopathy (CNM). We aimed to analyze the clinical, pathological and genetic characteristic of patients with DNM2-related CNM in China. We studied seven patients, all of whom underwent clinical examination, muscle biopsy, electromyography, and genetic tests. DNM2 gene analysis revealed two sporadic patients harboring the p.E368K mutation, two patients from one family carrying p.R369Q, one with p.R369W, one with p.R523G and one with compound heterozygous mutations of p.R522H and p.R718Q. In DNM2-related CNM, ptosis, ophthalmoplegia/paresis, and facial weakness are the frequently observed manifestations. However, among these seven patients, only one had bilateral ptosis; one, external ophthalmoplegia and one, facial weakness. Muscle biopsy showed that the percentage of muscle fibers with centrally located nuclei ranged from 67 to 93 %, all with radial sarcoplasmic strands. To date, five different CNM-related DNM2 mutations have been observed in China. Here, a patient with compound heterozygous DNM2 mutations was reported for the first time. Facial weakness, ptosis and ophthalmoplegia did not appear to be common in Chinese patients. This study on Chinese patients broadens the spectrum of DNM2-related CNM.

Objectives To investigate the clinical predictors and survival implications of perineural invasion (PNI) in parotid gland malignancies. Study Design Case series with chart review. Setting Tertiary care medical center. Subjects and Methods Patients with parotid gland malignancies treated surgically from 2000 to 2015 were retrospectively identified in the Head and Neck Cancer Registry at a single institution. Data points were extracted from the medical record and original pathology reports. Results In total, 186 patients with parotid gland malignancies were identified with a mean follow-up of 5.2 years. Salivary duct carcinoma (45), mucoepidermoid carcinoma (44), and acinic cell carcinoma (26) were the most common histologic types. A total of 46.2% of tumors were found to have PNI. At the time of presentation, facial nerve paresis (odds ratio [OR], 64.7; P < .001) and facial pain (OR, 3.7; P = .002) but not facial paresthesia or anesthesia (OR, 2.8, P = .085) were predictive of PNI. Malignancies with PNI were significantly more likely to be of advanced T and N classification, be high-risk pathologic types, and have positive margins and angiolymphatic invasion. PNI positivity was associated with worse overall (hazard ratio, 2.62; P = .001) and disease-free survival (4.18; P < .001) on univariate Cox regression analysis. However, when controlling for other negative prognosticators, age, and adjuvant therapy, PNI did not have a statistically significant effect on disease-free or overall survival. Conclusions PNI is strongly correlated with more aggressive parotid gland malignancies but is not an independent predictor of worse survival. Facial paresis and pain were predictive of PNI positivity, and facial paresis correlated with worse overall and disease-free survival.
