The masking-level difference (MLD) was measured in a group of adult listeners having unilateral otosclerosis before stapedectomy surgery, 1 month following surgery, and 1 year following surgery. The results indicated that the MLD in this group improved significantly over each of the sequential tests. In contrast, for a group of normal-hearing listeners, the MLD did not change significantly over...

Cortisone is used in various inner ear disorders such as sudden hearing loss. However, it is not known if the doses of prednisolone employed in therapy increase the cortisol level in the inner ear. To evaluate the level of cortisol within the perilymph after intravenous administration of 125 and 250 mg of prednisolone, serum and perilymph samples of 29 consecutive patients with clinical otoscle...

This article reviews information on some auditory disorders that have in common a disturbance in loudness perception. The perceptual disturbances in these disorders have interchangeably been labeled "hyperacusis," "dysacusis," or "phonophobia." Our question concerns whether the loudness disturbances associated with these auditory disorders are sufficiently different as not to justify the equiva...

introduction carhart's notch (cn) is a major audiometric criterion for diagnosis of otosclerosis; it is an abnormal audiometric pattern due to fixation of stapes and relative reduction in perilymphatic motion. methods 130 patients (146 diseased ears) were evaluated in this study. audiometric tests were performed for each patient 2 weeks before and 6 month after surgery, and the average decline ...

BACKGROUND AND PURPOSE Sensorineural hearing loss (SNHL) is a rare complication of stapes surgery that may arise for many reasons. Usually, the pathogenesis of SNHL can be established by clinical and CT examinations. The purpose of this study was to evaluate the utility of MR imaging when CT findings are normal or not contributive. METHODS Eleven patients with SNHL (in some instances, associa...

The presented article shows the current scientific concept including diagnostics and therapy of otosclerosis with an emphasis on surgical treatment options. The three main proposed causes for otosclerosis are viral and hormonal origin as well as a genetic predisposition. In 25 to 50% a familiar accumulation can be seen. Usually patients become aware of clinical problems by a progressive middle ...

It is also important to determine if the malleus is mobile by massaging the tympanic membrane under a Siebel otoscope and microscope. If the malleus is mobile, a normal stapedectomy can be performed, consisting of an incus to oval window prosthesis. This operation has a high rate of success (95%). If the malleus is fixed, however, it is necessary to create a malleus to oval window prosthesis. B...

Stapedotomy is primarily performed to treat hearing loss secondary to otospongiosis, although some patients find that the accompanying tinnitus is more bothersome than the hearing loss. We prospectively studied 23 consecutive patients with tinnitus secondary to otospongiosis who had undergone stapedotomy, and we compared their preand postoperative medical and audiologic findings. Patients’ anno...

BACKGROUND: The main cause of conductive hearing loss in the presence a completely normal tympanic membrane is otosclerosis. There are different types prostheses that could be used operation with materials, designs, and shapes. utilized this study including both Teflon Robinson assessed. aim our work to match determine surgical steps, postoperative results, complications piston titanium prosthe...
