Otosclerosis is characterized by the fixation of the stapes to the oval window, thereby impairing acoustic signal absorbance. A commonly used surgical technique for improving hearing in cases of otosclerosis is stapedotomy. However, it is unclear whether this surgery restores all the physical characteristics of the tympano-ossicular system.

- Endolymphatic hydrops is linked to Ménière’s disease and can be assessed through wideband tympanometry, which measures acoustic absorbance in the middle ear to detect early changes.
- The study aimed to compare the acoustic absorbance behaviors of symptomatic and asymptomatic Ménière’s patients against healthy controls using tympanometry at different pressures.
- Results showed significant differences in peak pressure and absorbance values between the groups, indicating that wideband tympanometry can effectively identify Ménière’s disease and differentiate between asymptomatic and symptomatic conditions.
Introduction: Perforation of the tympanic membrane is a reasonably frequent diagnosis in otorhinolaryngologists' offices. The expectant management is to wait for spontaneous healing, which usually occurs in almost all cases in a few weeks. However, while waiting for healing to be completed, the patients may experience uncomfortable symptoms.

Methods: Open, randomized-controlled trial. Eighty patients submitted to unilateral or bilateral ear grommet tympanostomy were included and divided into two groups: Auricular Protection and Non-Protection to water during bathing and activities in water.
Introduction: Tympanometry is currently the most frequently used tool for assessing the status of the middle ear, commonly assessed using a single 226Hz tone. However, the use of the Acoustic Immittance Measures with a wideband stimulus is a promising high-resolution evaluation, especially in individuals known to have middle ear alterations, such as Down syndrome patients.
Objective: The aim of this study was to analyze the acoustic absorbance measurements in children with Down syndrome.
Unlabelled: Exuberant scarring tissue formation is among the failure causes of tracheal stenosis surgery. Dressings that could avoid such reaction could be very helpful in these cases. Bacterial cellulose, produced by acetobacter xylinun can be useful in these cases.
