Clinical evaluation of balloon dilation Eustachian tuboplasty in the Eustachian tube dysfunction.

The development of minimally invasive procedures such as the balloon dilation Eustachian tuboplasty (BET) is an alternative to the grommet tympanum membrane. BET is applied in the cases where, after elimination of all factors influencing the ET and middle ear functioning, no sufficient improvement is observed. The aim of this study was to present the therapeutic benefits of the BET method in the treatment of ETD caused by disorders in the middle ear ventilation.

The topographical anatomy of the round window and related structures for the purpose of cochlear implant surgery.

The treatment of total deafness using a cochlear implant has now become a routine medical procedure. The tendency to expand the audiological indications for cochlear stimulation and to preserve the remnants of hearing has brought new problems. The authors have studied the topographical anatomy of the internal structures of the ear in the area where cochleostomy is usually performed and an implant electrode inserted.
