BACKGROUND Middle ear surgery techniques can improve hearing destroyed by disease, but results of treatment are difficult to predict. Therefore, researchers use a Laser Doppler Vibrometer to measure vibrations of human middle ear ossicles. MATERIAL/METHODS Measurements of ossicular chain vibrations are performed on fresh human temporal bone specimens using Laser Doppler Vibrometer. Vibrations...

BACKGROUND The principal objective of ossiculoplasty is to reconstruct the sound-conducting system in the ear to the best possible degree after the elimination of pathological lesions from the middle ear. The ossicular chain is reconstructed with the use of the patient's own properly modelled ossicles and synthetic prostheses. The objective of the study was to assess the degree of hearing impro...

SUMMARY A subset of patients presents with unilateral conductive hearing loss, a normal pinna or grade I microtia, and mild external auditory canal stenosis. The physical findings of microtia and a small external canal are commonly absent or subtle in this group of patients, who are being commonly referred for imaging to evaluate isolated conductive hearing loss. We present a case series of pat...

cerebellopontine angle, the mastoid, the middle ear and the external auditory canal. Of these, the mastoid cavity is the least frequent site of origin. Herein, we report an extremely rare case of congenital cholesteatoma of mastoid origin with extension into the epitympanum and presentation of conductive hearing loss. Computed tomography (CT) displayed anatomic anomalies including ossicular ero...

OBJECTIVE To determine functional results after lateral semicircular canal fenestration on congenital conductive hearing loss. STUDY DESIGN Case series with chart review. SETTING Amir-Alam otolaryngology tertiary referral center. SUBJECTS AND METHODS Twenty patients with congenital oval window malformations who were not candidates for ossicular reconstruction underwent lateral semicircula...
