Otoscopic examination revealed a normal left exter-nal auditory canal and tympanic membrane with good mobility. The right external auditory canal was also normal, and the tympanic membrane demonstrated normal mobility on pneumatic otoscopy. However,

2020年11月15日 · Otosclerosis is a pathological bone remodeling process in which the normal, dense endochondral bone of the otic capsule is replaced by one or more foci of irregularly laid spongy bone that subsequently hardens abnormally and impairs function; the condition most commonly involves the stapes region.

2024年7月25日 · On otoscopy, there are usually minimal or no findings, except in severe cases where cochlear involvement can result in hyperemia of the cochlear promontory (Schwartze sign) 1-3. On pure-tone audiometry, there may be a characteristic decrease in bone conduction at 2000 Hz (Carhart notch).
Imaging in otosclerosis: A pictorial review - PMC - PubMed …
This pictorial review aims to acquaint the reader with the pathology and clinical features of otosclerosis, the classical imaging appearances on CT and MRI, a radiological checklist for preoperative CT evaluation of otosclerosis, imaging mimics and a few examples of post-stapedectomy imaging and complications.

2018年2月1日 · Simply put, not all of the ears with otosclerosis show a reduced tympanometric compliance and not all of the tympanograms with reduced compliance are caused by otosclerosis. The following section describes the science behind differentiation of the underlying middle ear pathologies with the use of immittance measurements.

Clinical Evaluation of the Patient with Otosclerosis
2018年2月1日 · Otosclerosis classically presents in an adult with progressive unilateral conductive or mixed hearing loss, absent stapedial reflexes and normal otoscopy. An examination using a 512 Hz tuning fork is essential to diagnosis; if the examination does not correlate with the audiogram, repeat the audiogram.
Role of Radiologic Imaging in Otosclerosis - Springer
Pre-operative CT imaging can help define the extent of bone involvement in otosclerosis and may help avoid surgical complications due to variant anatomy or unsuspected alternative causes of conductive hearing loss. In patients with recurrent hearing loss after surgery, CT imaging can clarify prosthesis position and re-assess anatomy.
Objectives The present paper aims to review the most recent literature on the use of imaging studies in otosclerosis for the most varied purposes, from routine application and differential diagnosis to prognostic prediction and investigation of surgical failure.
