Otosclerosis increases the stiffness of the middle-ear system, raising its resonant frequency. This can be quantified using multi-frequency tympanometry. Thus, a high resonant-frequency pathology such as otosclerosis can be differentiated from low resonant-frequency pathologies such as ossicular discontinuity. [citation needed]
Stapedectomy is a surgical procedure in which the stapes bone is removed from the middle ear and replaced with a prosthesis.. If the stapes footplate is fixed in position, rather than being normally mobile, the result is a conductive hearing loss.
Whilst hearing loss is a common symptom in many diseases of the ear, for example in otosclerosis (abnormal bone growth in the ear), [3] the white, chalky patches on the tympanic membrane are fairly characteristic of tympanosclerosis. Cholesteatoma is similar in appearance but the whiteness is behind the tympanic membrane, rather than inside.
The World Health Organization (WHO) published the WHO Surgical Safety Checklist in 2008 in order to increase the safety of patients undergoing surgery. [1] The checklist serves to remind the surgical team of important items to be performed before and after the surgical procedure in order to reduce adverse events such as surgical site infections or retained instruments.

A case history (usually a written form, with questionnaire) can provide valuable information about the context of the hearing loss, and indicate what kind of diagnostic procedures to employ. Examinations include otoscopy, tympanometry, and differential testing with the Weber, Rinne, Bing and Schwabach tests. In case of infection or inflammation ...
Endoscopic thoracic sympathectomy (ETS) is a surgical procedure in which a portion of the sympathetic nerve trunk in the thoracic region is destroyed. [1] [2] ETS is used to treat excessive sweating in certain parts of the body (focal hyperhidrosis), facial flushing, Raynaud's disease and reflex sympathetic dystrophy.
Since the inner ear is not directly accessible to instruments, identification is by patient report of the symptoms and audiometric testing. Of those who present to their doctor with sensorineural hearing loss, 90% report having diminished hearing, 57% report having a plugged feeling in ear, and 49% report having ringing in ear ().
This category contains those articles about the side effects of medications. Some side effects are not adverse. For example, the anti-depressant Welbutrin helps some to quit smoking. Other beneficial side effects of medications can be weight loss. A side effect of insulin is that it removes potassium ions from the blood stream and into cells.
