Disequilibrium is one of the most popular symptoms of vestibular schwannoma, next to the hearing disturbance and tinnitus. In our institute, the cases with vestibular schwannoma were concurrently investigated with neurophysiological studies like pure tone hearing of Gardner-Robertson method (GR), auditory brainstem response (ABR), vestibular evoked myogenic potential (VEMP) and Stabilometry. Among them, VEMP study gives us the most valuable informations. In fact, both qualitative and quantitative improvements of VEMP have been verified in association with the symptomatic recovery of disequilibrium.

Objectives: Vocal cord palsy secondary to sarcoidosis is a rare manifestation and it is very unusual for the patient to present with it as a chief complaint. This is the first literature review conducted highlighting the importance of this condition. 46 years lady presented with hoarseness of voice without any significant history related to upper airway or lung condition. Suffers only from obesity. Naso-endoscopic examinations showed left vocal cord palsy. CT scan of chest confirmed hilar lymphadenopathy which was diagnosed as sarcoidosis with endobronchial ultrasound (EBUS) guided lymph node biopsy. Symptoms were related to neuro-sarcoidosis and peripheral recurrent laryngeal nerve neuritis. No local compressive sings noted on imaging. The patient was treated with local vocal cord injection and steroids were not suggested considering the patient’s obesity. Methods: The literature review revealed only twenty-three reported cases. Number of cases included were 16 in relation to the nerve pathway. Cranial cases were excluded. One case report was due to peripheral neuro-sarcoidosis. Results: The common practice was to manage with oral steroids, however, only few cases used injection laryngoplasty as treatment. Injection laryngoplasty is actively practiced in the UK under the National Institute of health and care Excellence (NICE) guidelines [ IPG130] was published on the 22nd of June 2005. Conclusion: Knowledge about vocal fold paralysis in sarcoidosis needs highlighting and should be considered by clinicians in cases that may initially appear to be idiopathic in nature without any chest complains related.

Introduction: Brachial plexus schwannomas is a rare entity, only about 5% arise from the brachial plexus. The diagnosis can be a challenge to surgeons. we provide a case report of a brachial plexus schwannoma and we highlight the clinical aspects of these tumors, the role of imaging in the diagnosis, the surgical treatment, and its outcomes.. Case Report: A 62-year-old male patient, presented with a slowly growing neck mass that had been noted for more than 20 years, associated with slowly evolving weakness of the left upper limb. clinically a 4 x 5 cm mass located in the left supraclavicular region was found. (CT) showed a well- encapsulated, low-density mass near the cervical spinal root. The mass was excised through a supraclavicular incision. The histopathology of the tumor was consistent with Schwannoma. A neurological deficit of the left arm was found immediately after the operation. The patient received sessions of rehabilitation therapy only. Six months later, the motor neurological functions had partially recovered. Discussion: Schwannomas are indolent tumors but may present with symptoms secondary to nerve compression. Clinically, the most common presenting symptoms are palpable mass, pain paresthesia/numbness, and weakness. Contrast-enhanced CT and magnetic resonance images (MRI) are helpful in the pre-operative diagnosis. MR imaging is the study of choice to delineate the margins of the tumor from surrounding tissues with the greatest contrast. The choice of surgical approach is important and can be selected according to the tumor size, tumor site, and relationship with adjacent organs. A variety of surgical approaches are used. Recently, intracapsular enucleation has been introduced to preserve the neurological functions, it is possible to open the capsule and shell out the tumor, thereby leaving the capsular nerve undisturbed and possibly avoiding functional deficits [1]. Despite the extrafascicular characterization of the tumor, it is almost always possible to find a small fascicle entering and exiting the proximal and distal poles of the tumors, such as in our reported case. This fascicle does not transmit nerve action potential and can be sectioned so that the tumor can be.

Messerklinger initially characterized sinonasal mucociliary clearance patterns in the 1950’s using India ink particles and hypothesized that inflammatory disease within the sinuses, as well as anatomic variants, could obstruct mucus outflow. He introduced use of the endoscope for diagnostic evaluation, as well as surgical principles known as the Messerklinger technique [1]. In the following 70 years his technique, known as Endoscopic Sinus Surgery (ESS), was refined and popularized by Stammberger, Kennedy, and others [2,3]. Both emphasized the preservation of normal anatomic structures and re-establishment of natural mucociliary clearance patterns. Towards that end, Kennedy viewed the surgery as a functional and minimally invasive procedure, adding the term “functional” to ESS, with the procedure now widely known as Functional Endoscopic Surgery (FESS) [4]. Since then, minimally invasive endoscopic techniques have been further refined by a multitude of talented multi-disciplinary physicians, too numerous to name here [5].

Cochlear synapthopathy, is a condition where the damage is located at the level of the synapses between IHCs and type-I afferent auditory nerve fibres. The disrupted function of these synapses, either can or can’t be re-established, thus resulting in various signal coding deficits and hearing impairment. Cochlear synaptopathy can be widely present in ears with intact hair cell populations and relatively ‘normal’ audiograms, representing the major cause of “hidden” hearing loss. The present study reviews the major mechanisms involved in hidden hearing loss, emphasizing on future directions regarding appropriate diagnosis of cochlear synaptopathy in humans.

Deterioration of auditory thresholds in young children is directly associated with negative impact on language development. Early detection of the cause of sensorineural hearing loss eases proper intervention and signalizes valuable prognostic data. Nowadays, the etiology of pediatric hearing loss has been modified, attributable to progresses in gene testing and adequate management of birth infections. This paper updates well known risk factors for progression along with fluctuation of hearing acuity involving health hazard indicators, auditory, laboratory and clinical manifestations of such young patients. This review takes into consideration the most well-known risk indicators associated with an increased likelihood of progressive hearing loss (including but not limited to neonatal intensive care unit admission, family history of hearing loss, various syndromes, prenatal and postnatal infections etc.). Prompt post neonatal monitoring of hearing, leading to early hearing loss identification, is crucial to optimize management and therefore appropriate intervention.

Neoplasms of the parapharyngeal space are extremely rare and represent 0.5% of all tumors of the head and neck. The majority of the mare benign and originate in the salivary gland region. Pleomorphic adenoma is the most common salivary glandular benign tumor. We report the case of a 44-year-old woman presented with the complaint of a dysphagia and swelling of the left soft palate. Cervical computed tomography showing very limited mass in the left parapharyngeal space. The patient was operated on and total excision of the lesion was carried out using a trans-oral approach. Histological examination revealed a pleomorphic adenoma. No post-surgical complications were noted. No recurrence was noted during the 2 years of follow-up.

Meniere’s disease (MD) is a chronic heterogeneous disorder recently found to involve multiple rare and common variants in several genes. It almost always necessitates management for a sustained period of time. Treatment options focus on improving quality of life in MD patients. Control is not always easy to achieve, requiring multidrug treatments, and even surgical procedures. Migraine, dyslipidemia, obesity, diabetes, sleep apnea, hypertension, and atherosclerosis are among the major diseases that are associated with MD and often require medical management. Migraine prophylaxis and trigger elimination, magnesium supplementation, low sodium intake, diuretics, anticoagulants, and antihypertensives are among the treatments used initially. Steroids administered orally or intratympanically are used if medical control is not beneficial. Ablation remains the definitive treatment in unilateral cases experiencing management failure, thus facilitating a customized vestibular rehabilitation protocol. Genetic study should be implemented especially when familial MD is considered. Proper gene variance targeting in MD can provide in the immediate future candidates for potential gene therapy.

Neck swelling is a common presentation in the general population and has a number of possible causes. Lymph nodes are the commonest among all. Schwannomas are benign slow growing tumors that arise from the Schwann cells of nerve, also called neurilemmoma. Head and Neck schwannomas usually present as solitary with well demarcated lesions. These tumors usually remain asymptomatic but present as slowly enlarging neck masses. Its origin is only determined during surgical procedure along the course and distribution of the nerve. Preoperative diagnosis is usually made by physical examination and aided by ultrasonography, magnetic resonance imaging or computed tomography and fine needle aspiration cytology but open biopsy is not recommended. The main stay of treatment is complete intracapsular excision with preserving the nerve of origin.

Treatment of earwax often involves the use of a wax softening agent (cerumenolytic) with or without antimicrobial agents to easily removing. Cerumenolytic agents used to remove and soften earwax areoil-based treatments, water-based treatments. Fixed drug eruption (FDE) is a well-defined, circular, hyperpigmented plaque that usually occurs on the trunk, hands mucosal surfaces, after a systemical application of drugs. In this report, a case with FDE developed after a cerumenolytic agent (hydrogen peroxide and boric acid in water). A definitive diagnosis was made with skin punch biopsy and FDE was treated with oral levocetirizine and topical mometasone.
