One of the paths in the investigation of congenital sensorineural hearing loss (CSNHL) is to try to characterize its etiology through the inner ear evaluation using high resolution computer tomography (CT) scans. With minor malformation, it is not always possible for a simple visual inspection to recognize if the structure in the inner ear is normal or not. To verify if measurements of the inner ear are predictive of sensorineural hearing loss (SNHL) and suggest cutoff points of size limits.

Introduction: Fibrin tissue adhesive, which has applications in several areas of medicine, can be prepared by different methods.
Aim: To compare fibrin tissue adhesives prepared by 3 different methods.
Method: In this prospective experimental laboratory study, fibrin tissue adhesives prepared by the use of plasma fibrinogen (group 1), cryoprecipitation (group 2), and precipitation by ammonium sulfate (group 3) were tested on 15 rabbits and 10 fragments of dura mater.
Several studies have shown that cochlear implants may reduce or even eliminate tinnitus in patients with bilateral profound hearing loss. However, there are not consistent references regarding ipsilateral tinnitus compared to unilateral profound hearing loss. The aim of this paper is to describe audiological results of a patient with asymmetrical hearing loss with incapacitating ipsilateral tinnitus in the ear subjected to cochlear implant surgery.

Aim: To evaluate the experience of the otorhinolaryngology unit, Parana University, relative to stapes surgery done in the residency training program.
