Paralysie facial nerve

Introduction Vestibular schwannomas (VS) are the most common benign neoplasms of a cerebellopontine angle (CPA), which arise from the Schwann cells of the vestibulocochlear nerve. Eighty percent of CPA tumors are VS followed by meningioma as the second common mass lesion in this critical potential space. Treatment options range from watchful waiting with serial imaging studies to radiosurgery or a microsurgical excision or a combination of surgery and radiation therapy. The primary objective of the study was to assess hearing and facial nerve status before and after the surgery via the retrosigmoid approach...

OBJECTIVES: To analyze medical malpractice lawsuit trends pertaining to cases of vestibular schwannomas (VS). METHODS: Two major computerized legal databases (LexisNexis and WestLaw) were queried and reviewed for evaluation of all the US state and federal court records from civil trials alleging malpractice between 1976 and 2016. RESULTS: A total of 32 VS cases were identified. Allegations were divided into four categories: misdiagnosis/delayed diagnosis (47%), postoperative complications (44%), failure of informed consent or information sharing (16%), and other (3%)...

OBJECTIVE: Cochlear implantation is routinely performed all over the world via the post-auricular, facial recess approach. Our case study describes the middle fossa approach for the management of bilateral profound sensorineural hearing loss in a female child with multiple external, middle and inner ear malformations. The middle fossa approach has been reported sporadically and has been used inconsistently in patients with chronic otitis media and inner ear malformations. CASE STUDY: A 3-year-old female child presented with bilateral profound sensorineural hearing loss, bilateral anotia, right cochlear nerve agenesis, right facial paralysis, bilateral mild inner ear dysplasia and an aberrant left facial nerve covering the left round window...

Vasculitic midline destructive lesions can be a complication of cocaine use. We report a 44-year-old man who presented with a two months history of left facial pain associated with ipsilateral facial paralysis and a cheek phlegmon. Magnetic resonance imaging showed broad soft tissue destruction linked to important cranial nerve involvement. Antibiotic and antifungal therapy was started and multiple surgical debridement procedures were performed, with no clinical improvement. Microbiological analysis was negative...

BACKGROUND: Bell's palsy is a peripheral paralysis of the seventh cranial nerve, the etiology of which is unknown. Using PCR technology, it is possible to sample accessible body fluids and identify possible viral factors. The purpose of this research was to investigate its connection to the herpes virus family by testing for the presence of the virus in the saliva and tear fluid of Bell's palsy patients. METHODS: Saliva and tears were collected from 42 children and adolescents who had idiopathic facial nerve paralysis...

Bell's palsy is an idiopathic facial paralysis which is a lower motor neuron disorder. The ultimate goal of treatment is normalization of paralyzed hemi -face with symmetrical smile and face along with corneal protection. The aim of this article is to revisit all the current options available for management of facial nerve paralysis with main concentration on best surgical management in long-standing cases i.e. regional muscle transfer using temporalis tendon with fascia lata. A Case Report of a 38 year old Indian male is reported with chronic facial palsy...

Various donor muscles have been identified for restoring facial function due to longstanding facial paralysis. Donor muscles such as the gracilis and latissimus dorsi are frequently used and often produce one or two reliable vectors of force. However, there are drawbacks of using these muscles, including the instability of separating multivector functioning muscle units and limited amount of muscle contraction. Serratus anterior muscle transfer has the advantages of multiple independently functioning motor units that can be created with a single neurovascular pedicle...

The purpose of this study was to assess the utility of a fascicular turnover flap for facial nerve repair and to investigate its possible application in the field of facial nerve repair using a rat model of facial paralysis. Twenty-four Wistar rats were used in this study. A left vibrissal muscle palsy model was established via excision of the buccal and marginal branches through a periauricular incision. In Group 1, the nerve gap was not reconstructed. In Group 2, the nerve gap of the marginal mandibular branch was reconstructed using an autograft, and in Group 3, the gap was reconstructed using a fascicular turnover flap...

OBJECTIVE: To observe the clinical efficacy of methycobal iontophoresis combined with balance acupuncture in the treatment of peripheral facial paralysis. METHODS: A total of 108 patients with peripheral facial paralysis were randomly divided into a methycobal iontophoresis combined with balance acupuncture group (a combined group), a methycobal iontophoresis group and a simple balance acupuncture group, 36 cases in each one. Basic medical treatment were given in the three groups...

The standard local treatment for early-stage tongue cancer with no clinical lymph node metastases is partial glossectomy. The frequency of occult lymph node metastasis is ~20-30%. Thus, whether prophylactic neck dissection with glossectomy or glossectomy alone should be performed has been a controversial issue since the 1980s. Both treatments have advantages and disadvantages; however, especially in cases involving prophylactic neck dissection, surgical invasion and complications including the cosmetic disadvantage caused by neck skin incision, accessory nerve paralysis or facial nerve (mandibular marginal branch) paralysis, stiffness of the shoulder or neck and a feeling of neck tightness have been considered issues that could be solved by providing less-invasive treatment to the 70-80% of patients without occult lymph node metastasis...

INTRODUCTION: The facial nerve is responsible for any facial expression channeling human emotions. Facial paralysis causes asymmetry, lagophthalmus, oral incontinence, and social limitations. Facial dynamics may be re-established with cross-face-nerve-grafts (CFNG). Our aim was to reappraise the zygomaticobuccal branch system relevant for facial reanimation surgery with respect to anastomoses and crossings. MATERIALS AND METHODS: Dissection was performed on 106 facial halves of 53 fresh frozen cadavers...

Introduction Warthin's tumor is a non-malignant tumor that occurs in major salivary glands. Diagnostics include an interview and physical examination as well as additional tests - ultrasonography, magnetic resonance tomography, fine-needle aspiration biopsy. Surgical tumor resection remains the method of treatment, the scope of which includes techniques from extracapsular tumor resection to a full range of parotidectomy. Material and methods A retrospective analysis was conducted for available medical records of 53 patients treated surgically at the Department of Otolaryngology and Laryngological Oncology at the Collegium Medicum of the Nicolaus Copernicus University in Toruń in 2009-2016...

Ramsay Hunt syndrome is a type of acute herpes zoster, which occurs by reactivation of the varicella-zoster virus at the geniculate ganglion. Clinical presentation of Ramsay Hunt syndrome includes a vesicular rash on the ear (herpes zoster oticus) or in the oral mucosa accompanied by acute peripheral facial nerve paralysis. Other cranial nerves such as V, IX, XI, and XII are often involved. Additional variability of the clinical picture of Ramsay Hunt syndrome is produced by varying patterns of skin involvement explained by individual anastomoses between cranial and cervical nerves...

The efficacy of electroacupuncture in the treatment of peripheral facial paralysis is known, but the specific mechanism has not been clarified. Glial cell-derived neurotrophic factor (GDNF) has been shown to protect neurons by binding to N-cadherin. Our previous results have shown that electroacupuncture could increase the expression of N-cadherin mRNA in facial neurons and promote facial nerve regeneration. In this study, the potential mechanisms by which electroacupuncture promotes nerve regeneration were elucidated through assessing the effects of electroacupuncture on GDNF and N-cadherin expression in facial motoneurons of rabbits with peripheral facial nerve crush injury...

Objective: To investigate the clinical characteristics and risk-factors of traumatic basal ganglia stroke (TBGS) in children. Methods: A retrospective case study was conducted to analyze the clinical and imaging data of 16 children with TBGS in the First Hospital of Jilin University from January 2014 to June 2017. A total of 16 TBGS cases (11 males, 5 females) were diagnosed and the age ranged from 0.5 to 13.0 years. The prognosis of children with TBGS at different ages (≥5 years and<5 years) and with different traumatic stroke (infarction and hemorrhage) were compared...

OBJECTIVES: This study aims to evaluate the effectiveness of facial rehabilitation (FR) in patients with chronic facial nerve paralysis (FNP) and describe factors that predict improved facial nerve function after FR in this patient population. STUDY DESIGN: Retrospective case review. SETTING: Tertiary referral center. PATIENTS: Around 241 patients were referred to a university hospital facial rehabilitation (FR) program for FNP between 1995 and 2016...

BACKGROUND: Chondromyxoid fibroma (CMF) is a rare benign bone tumour of cartilaginous origin, which usually affects the metaphysis of the long bone. Involvement of the temporal bone is extremely rare. Patients with CMF in the temporal bone can present some neurological deficits due to involvement of surrounding neural structures. CASE SUMMARY: We present the first case of histopathologically proven CMF originating in the temporal bone and involving the hypoglossal canal in a 40-year-old woman...

OBJECTIVES: To report a case of total facial paralysis as the result of a core needle biopsy. METHODS: Case report and literature review. RESULTS: A 70-year-old man was diagnosed with a deep lobe parotid tumor on computed tomography. During a core needle biopsy, he developed complete facial paralysis. The cause was discovered to be a direct stab injury to the main trunk of the facial nerve. CONCLUSIONS: When biopsying parotid lesions adjacent to the main trunk of the facial nerve, the use of smaller-gauge needles and additional patient counseling should be considered...

There are two important differentials for non-caseating granulomatous inflammatory tissue-leprosy and sarcoidosis-which presents a diagnostic challenge due to their histological similarities and specific geographical distribution. This article describes a rare presentation of systemic sarcoidosis called Heerfordt's syndrome with the triad of parotitis, uveitis, fever, and optional paralysis of facial nerve. This case was initially diagnosed as leprosy.

Two cases of lipomatosis of the parotid salivary gland in two dogs are reported. Both dogs were presented with a slow growing unilateral non-painful mass in the parotid region. The mass measured 12 and 15 cm on the longest axis for case 1 and 2 respectively. Initial incisional biopsies were suggestive of infiltrative lipoma or salivary gland adenocarcinoma. Case 2 underwent head radiographs that showed a soft tissue opacity on the area of the right parotid gland followed by a computed tomography that showed a multi-lobulated infiltrative mass occupying the right parotid gland...
