However implementing universal screening strategy is a challenge in many resource constrained settings. There are various limitations towards successful implementation of hearing screening program in the developing countries. The cost effectiveness of the screening program also needs to be considered in a resource constrained settings. We attempt to provide a viewpoint that can be potentially helpful for the successful implementation of hearing screening in a resource constrained settings of the developing countries.<br /><br /> To evaluate the pathological changes in the blood-perilymph, blood-endolymph, and blood-nerve barriers of a patient with idiopathic sudden sensorineural hearing loss (SSNHL).<br /><br /> Potential ossification or fibrosis in the inner ear was evaluated using temporal bone CT and MRI acquired using the 3-dimensional T2-weighted sampling perfection with application-optimized contrasts using a flip angle evolution sequence. Pathological changes in the barriers were analyzed by MRI obtained 4h after a single-dose intravenous injection of gadolinium chelate using a medium inversion-time inversion recovery imaging with magnitude reconstruction sequence.<br /><br /> The perilymph was absent, while significant enhancements of the vestibulocochlear nerve and the endolymphatic compartments were detected.<br /><br /> Significant injuries in the blood-endolymph and blood-vestibulocochlear nerve barriers and disabled perilymph production may contribute to the development of SSNHL with poor response to treatments.<br /><br />Significant injuries in the blood-endolymph and blood-vestibulocochlear nerve barriers and disabled perilymph production may contribute to the development of SSNHL with poor response to treatments.Endoscopes are increasingly being used in cholesteatoma surgeries either as an adjunct to microscopes or sometimes exclusively. Their role at present is more as adjunct to microscope which still remains the work-horse for mastoidectomy. However, as endoscopy and endoscopic instruments are increasingly getting refined, role of endoscopy in management of cholesteatoma is continuously being appraised with progressively newer studies. This review aims to assess outcomes of several studies in which endoscopic techniques were used in cholesteatoma surgery and recognize common trends. An extensive review of literature on this theme was performed. Sixteen studies comprising of 1685 patients treated endoscopically either exclusively or in combination with microscope were included. Intra-operatively, in 267 (15.82%) cases, residual cholesteatoma was identified by endoscope in hidden areas after completion of surgery with microscope. On follow-up, recidivism was identified in 108 cases (6.4%) in second look procedures. Common sites of recurrence were hidden areas like sinus tympani. This review while acknowledging the value of microscope, highlights the merit of endoscope usage in cholesteatoma surgery and its role in reducing recurrence.Middle ear osteoma is an extremely rare benign tumor of the middle ear. Due to its very slow growth rate and benign nature, osteoma of the middle ear can be found incidentally without causing any symptoms. The most common clinical signs are conductive hearing loss, the sense of fullness in the ear, tinnitus, and otorrhea. Small-sized osteomas can be misdiagnosed as otosclerosis without showing any signs other than conductive hearing loss. When the mass becomes very large, and symptoms caused by the tumor increase, treatment also becomes difficult. In this paper, we report a case of middle ear osteoma causing conductive hearing loss and effusion due to the effect of pressure on the middle ear ossicles and the Eustachian tube. We also present a review of the pertinent literature.The genesis of the Benign Paroxysmal Positional Vertigo (BPPV) seems to be related to some metabolic factors. These factors, such as vitamin D, glucocorticoids, and even thyroid and growth hormones, can affect bone metabolism and the mineralization of otoconia. It also seems to link to factors related to aging or nutritional habits. Besides, since the incidence of BPPV is quantitatively higher in women than in men, female sex steroids could be associated with this process. It could be useful to understand how these factors act in otoconial mineralization if we want to develop treatments aimed at preventing or delaying BPPV recurrences. In this review, we will analyze the role of these metabolic and hormonal factors in otoconial mineralization and in the treatment of BPPV.<br /><br /> Evidence suggests that glucocorticoids are important in the treatment of sudden hearing loss (SHL) and Meniere's disease (MD). However, different glucocorticoid administration methods may have a significant impact on treatment outcomes.<br /><br /> This study aimed to investigate effects of different glucocorticoid administration methods on sudden hearing loss and Meniere's disease.<br /><br /> In this study, glucocorticoids were administered orally in 18 patients, by retroauricular injection in 15 patients and by intratympanic injection in 15 patients. White blood cell (WBC) count, serum K<br /><br /> , fasting plasma glucose (FPG), body temperature, heart rate and blood pressure were used to evaluate effects of glucocorticoids on patients with hearing loss. [https://www.selleckchem.com/products/cwi1-2-hydrochloride.html CWI1-2 manufacturer] Visual analog scale (VAS) of pain and sleep disorders were also surveyed, and pure tone audiometry (PTA) results were compared among groups to evaluate efficacy of different glucocorticoids administration methods.<br /><br /> WBC count, heart rate and blood pressure were higher in patients taking oral glucocorticoids, while body temperature, serum K<br /><br /> and FPG levels did not change in all three groups.
