Intracanalicular vestibular schwannomas presenting with facial nerve paralysis.

BACKGROUND: To describe the surgical management and postoperative course of two patients presenting with facial nerve (FN) paralysis as one of the presenting symptoms of small intracanalicular vestibular schwannomas (VS). METHODS: Among 153 patients operated for VS since September 2010 to August 2017, two adult female patients presented with rapidly progressive hearing decrease, vestibular symptoms, and FN paralysis (House-Brackmann grades III and IV, respectively). In both cases, c.e. T1-weighted magnetic resonance imaging revealed an enhancing tumor within the internal auditory canal without lateral extension beyond the fundus. RESULTS: Retrosigmoid approach and excision of tumor showed that the origin of tumor was from the superior vestibular nerve, extrinsic to FN. Gross total tumor resection was obtained, with FN preservation. In the first case, a millimetric fragment of capsule was left because of tight adhesion on FN itself. Histopathology confirmed schwannoma. After surgery, both patients improved FN motor function. CONCLUSIONS: Although very rarely, VS may start clinically with FN palsy, mimicking FN schwannomas and other less common pathologies. This presentation is exceptional in patients with small intracanalicular VS. Early surgical resection is the only reliable treatment for decompression of nerve, avoiding a complete and not-reversible damage, with possible postoperative FN function improvement or complete recovery.

[Multiple erythema migrans and facial nerve paralysis: clinical manifestations of early disseminated Lyme borreliosis]. / Multilokuläre Erythemata migrantia und Fazialisparese : Klinische Manifestationsformen der disseminierten Frühinfektion der Lyme-Borreliose.

Lyme borreliosis is a common vector-borne disease in Europe. The infection follows different stages with a broad variability of clinical symptoms and manifestations in different organs. A 49-year-old man presented with flu-like symptoms, facial nerve paralysis and multiple erythematous macular on his trunk and extremities. We diagnosed Lyme disease (stage II) with facial nerve paralysis and multiple erythema migrans. Intravenous ceftriaxone led to complete healing of hissymptoms within 2 weeks.

[Facial nerve palsy. Not always that easy!]. / La vignette diagnostique de l'etudiant. La paralysie faciale ... pas toujours si facile que cela!

We report the case of a 45 years old woman who experienced two episodes of facial palsy, first on the left side, then on the other. This particular case allows us to discuss the diagnostic process and clinical reasoning to follow in front of this symptomatology -using a didactic questioning- and to briefly review the anatomy of the seventh cranial nerve. Treatment and possible complications are also discussed.

Hearing Preservation After Cochlear Reimplantation Using Electrocochleography: A Case Report.

Studies have shown that hearing preservation is possible in the context of reimplantation, but residual hearing could not be predicted or expected in these cases. We describe a case in which a patient with mild to profound sensorineural hearing loss who underwent cochlear implantation with a lateral wall array and had hearing preserved postoperatively. She developed facial nerve stimulation which was unresponsive to reprogramming. Using electrocochleography to measure intracochlear trauma during the insertion process, the patient underwent reimplantation with a perimodiolar electrode and hearing was preserved postoperatively. This case demonstrates the potential to use electrocochleography for hearing preservation during reimplantation. Laryngoscope, 131:2348-2351, 2021.

Atypical presentation of cat scratch disease: Parinaud's oculoglandular syndrome with facial nerve paresis.

A 28-year-old man presented to our clinic over the course of 3 weeks with symptoms that progressed from mild headaches to fever, fatigue, myalgia and an enlarged right preauricular lymph node with ipsilateral conjunctivitis and upper eyelid weakness. Our differential included Epstein Barr Virus/Cytomegalovirus mononucleosis, bacterial conjunctivitis and lymphoma. We evaluated with CBC, EBV IgM Ab, lactate dehydrogenase level and a CMV IgG Ab which were all within normal limits. During his third visit, we discovered our patient had been scratched by two stray kittens he had adopted 2 months prior. We confirmed the diagnosis with a positive Bartonella henselae IgG level and diagnosed him with cat scratch disease presenting as Parinaud's oculoglandular syndrome. He was treated with a 5-day course of Azithromycin 250 mg with definitive improvement.

[Primary cholesteatoma of the middle ear and petrosal bone]. / Perlak pierwotny ucha srodkowego i szczytu piramidy.

Petrosal cholesteatomas are rare lesions, which may be primary or acquired in nature. We report a case of primary cholesteatoma in petrous bone occurring in 51-year old woman who presented with a unilateral facial nerve palsy and conductive hearing loss, despite normal tympanic membrane appearance. Early diagnosis was facilitated by computed tomography scanning and magnetic resonance imaging. Complete cholesteatoma removal was accomplished using a transtemporal supralabyrinthine approach, which allowed hearing preservation. Facial nerve function is the main complication of these lesion. We suggest that use of CT scanning and MRI in unilateral conductive hearing loss may allow the earlier detection of the most cases of petrosal cholesteatomas.

Peripheral Nerve Field Stimulation (PNFS) as a Treatment Option for Intractable Radiation-Induced Facial Neuropathic Pain in a Survivor of Laryngeal Cancer: A Case Report.

BACKGROUND: Treatment-related chronic neuropathic pain represents a major and increasing cause of discomfort in cancer survivors. Unfortunately, in approximately 10%-15% of cases, pain is scarcely relieved by opioids and common painkillers. Thus, alternative measures to manage pain have recently been adopted in these patients. CASE DESCRIPTION: We report the case of a laryngeal cancer survivor who developed an intractable bilateral mandibular radiation-induced neuropathic pain syndrome. His pain was refractory to any pharmacological treatment, whereas the implant of bilateral subcutaneous facial electrodes led to the complete resolution of pain. CONCLUSIONS: To the best of our knowledge, this is the first report in literature describing peripheral nerve field stimulation as a treatment option for intractable cancer treatment-related chronic neuropathic pain. Peripheral nerve field stimulation appears to be a safe and effective procedure.

Fisher syndrome with delayed facial weakness and taste impairment: a case report.

A 55-year-old man was admitted to our hospital because of acute onset of diplopia and gait disturbance. On admission, ophthalmoplegia, ataxia and areflexia were observed. He was diagnosed with Fisher syndrome and given intravenous immunoglobulin therapy from day 6 to day 10 after disease onset. After treatment, ophthalmoplegia and ataxia began to improve. However, he developed taste impairment on day 13 and right hemifacial weakness on day 16 after onset. A blink reflex test revealed right facial nerve impairment. On day 42 after onset, facial weakness and taste impairment remitted, and the blink reflex test result was normalized without additional treatment. Although it has been known that 10% of patients with Fisher syndrome complicated by delayed facial nerve palsy, the mechanism of the facial nerve palsy has not been elucidated. Therefore, this is a significant report to describe delayed facial nerve palsy combined with taste impairment and successive recordings of blink reflex and facial nerve conduction in a patient with Fisher syndrome.

Giant cranial extradural primary fibroxanthoma: a case report.

Primary fibroxanthoma of the cranium is an extremely rare condition. Xanthomatous tumors of the central nervous system are occasionally associated with diseases such as Hand-Schuler-Christian disease, malignant fibrous histiocytoma, hyperlipidemia, and a complication of metabolic or storage disorders. However, until 2003, only a few cases of primary fibroxanthoma have been reported. We report a giant fibroxanthoma destroying the lateral skull base unaccompanied by a systemic or metabolic disease.

Infantile congenital petrosal cholesteatoma: a case report and literature review.

Congenital cholesteatoma of the middle ear is frequently seen in younger children including infant. By contrast, that of the petrous bone is rarely seen in younger children. We report an exceptional case occurring in 23-month-old infant who presented with unilateral facial nerve paralysis at about 18-month-old. Computed tomography and magnetic resonance imaging revealed congenital cholesteatoma measuring approximately 2 cm in the area of the right geniculate ganglion. The mass was completely eradicated via the middle fossa approach, which allowed for preservation of hearing. The facial nerve maintained intact during surgery and paralysis showed partial recovery after the operation. To our knowledge, the present case seems to be the youngest case of congenital petrosal cholesteatoma reported, and also demonstrates congenital petrosal cholesteatoma could exhibit facial nerve paralysis in early childhood.

Facial nerve palsy in a thirteen-year-old male youth with Kawasaki disease.

A 13-year-old male youth was hospitalized with Kawasaki disease. In the course of the disease he developed a facial nerve palsy and an aneurysm of the right coronary artery. After treatment with immunoglobulins both complications disappeared within 10 days and 1 month, respectively.

Importance of facial expression in facial nerve rehabilitation.

PURPOSE OF REVIEW: This review discusses contemporary evidence for the importance of facial expression to human beings. Strategies for management of patients with facial nerve dysfunction are discussed. RECENT FINDINGS: The purpose of facial expression from a cognitive neuroscience perspective has become clearer, including its role in emotional communication and identification. Facial retraining may have a role in rehabilitation. SUMMARY: Greater awareness of the biologic basis for facial expression may lead us to pay increased attention to evaluation and treatment of this component of facial nerve dysfunction. The timing of intervention remains important, and many effective techniques exist.

Otomastoiditis-related facial nerve palsy.

A 9-year-old girl with persistent otitis media, despite antibiotic therapy developed a facial nerve palsy. Computed tomography (CT) scan revealed ipsilateral mastoiditis, prompting admission for intravenous antibiotic and steroid therapies. Acute mastoiditis, uncommon in the post-antibiotic era, is usually diagnosed on physical examination findings, but two variants, masked mastoiditis or silent mastoiditis, may be difficult to appreciate clinically. Patients who present with facial nerve palsy in the setting of persistent otitis media should undergo CT scan for evaluation of intracerebral or extracerebral pathology, including mastoiditis. Failure to identify associated concomitant pathology may result in treatment failure or persistent neurological deficit.

Intratemporal traumatic neuromas of the facial nerve: evidence for multiple etiologies.

OBJECTIVE: To describe 2 patients with traumatic neuromas of the intratemporal facial nerve in the absence of trauma. STUDY DESIGN: Retrospective case review. SETTING: Tertiary care referral center. PATIENTS: Patients included underwent resection of an intratemporal facial nerve mass. Upon pathologic evaluation, the patients were found to have traumatic neuromas of the facial nerve. INTERVENTION(S): Patients underwent resection of an intratemporal facial traumatic neuroma. Histopathologic evaluation was performed including an immunohistochemistry evaluation. RESULTS: Two patients were identified with intratemporal facial nerve traumatic neuromas. The patients had no significant history of trauma or chronic inflammatory process. Pathologic evaluations, including immunohistochemistry, of the excised masses were consistent with traumatic neuromas. All tumors were noted to have a disorganized collection of axons and were not consistent with the expected diagnosis of schwannoma. Tumors involved the tympanic and vertical segments of the facial nerve. A cavernous angioma was found within one mass and is thought to be the etiology of neuroma formation. CONCLUSION: Traumatic neuromas are possible in the intratemporal facial nerve in the absence of trauma. A cavernous angioma of the facial nerve is a newly described possible cause of traumatic neuroma formation.

[Moyamoya disease].

Moyamoya syndrome is a rare chronic progressive disease of brain vessels in which certain arteries in the brain are constricted. During the disease a collateral circulation develops around the blocked vessels to compensate for the blockage, and on angiography these collateral vessels have the appearance of a "puff of smoke". Moyamoya syndrome is extremely rare disease, especially outside of Japan We describe a clinical case of a 27-year-old patient from Tomsk with Moyamoya disease. The clinical features are an acute stroke in the right middle cerebral artery with dysarthria and paralysis of VII and XII cranial nerves. The diagnosis of moyamoya is suggested by MRI-angiogram results in accordance to the diagnostic criteria.

Facial nerve palsy in childhood.

Facial nerve palsy in children is usually idiopathic but can also result from many conditions such as neoplasias, systemic diseases, or congenital anomalies with poor prognosis. Children with idiopathic facial palsy (Bell's palsy) have a very good prognosis, while treatment with prednisone does not certainly improve the outcome. The causes of facial nerve palsy in childhood differ from those in adults. A detailed investigation and differential diagnosis are recommended for facial palsy in children.

Idiopathic intracranial hypertension and facial palsy: case report and review of the literature.

We present the case of an 11-year-old obese girl who presented with idiopathic intracranial hypertension affecting first the lateral abducens nerve. She received acetazolamide, but 5 days later she developed lateral, peripheral facial palsy. Imaging evaluation was normal, which primarily excluded cerebral venous thrombosis and sustained the initial diagnosis. Despite some complicating factors (obesity, elevated intracranial pressure), prednisolone was administered for a short-term period to counteract the facial palsy. Ophthalmological residuals resolved within almost 1.5 months, while facial palsy receded after 4 months. Peripheral facial palsy is an extremely rare, but not unknown condition in idiopathic intracranial hypertension. As a symptom, it should be investigated thoroughly, primarily to exclude cerebral venous sinus thrombosis, before it can be attributed to idiopathic intracranial hypertension. As far as treatment is concerned, corticosteroids can be added to the initial treatment with acetazolamide, without worsening already elevated intracranial hypertension or ophthalmologic findings.
