OBJECTIVE. In children aged less than 10 years, to assess whether adenotonsillectomy has some permanent or transitory effect on middle ear pressure. MATERIAL AND METHODS. 20 children aged 4 to 9 years old (13 girls and 7 boys) participated in the study. The day before surgery and on days 1, 7, 14 and 21 after adenotonsillectomy both tympanometry and pure tone audiometry were performed. During s...

This article covers state-of-the-art instruments and devices specially designated for endoscopic ear surgery. New technologies stimulate the creation of special endoscopic equipment and microinstruments specially designed to satisfy the exclusive requirements of endoscopic ear surgery, which contribute to the progress of the procedure. The article presents the advantages and disadvantages of wo...

Health technology The study evaluated tympanomastoid surgery. A comparator was not explicitly stated at the outset, although it was likely to be no tympanomastoid surgery. The health technology was compared between two different patient groups. These were patients with wet ear suffering from chronic suppurative otitis media (CSOM) and patients with dry ear suffering from CSOM. The wet-ear group...

The use of an endoscope with varied angulations has allowed the surgeon to explore areas that were often not visualized using standard microscopic procedures. The endoscope has improved knowledge of the complex anatomy of mucosal fold and improved functional interventions in middle ear inflammatory disorders during middle ear surgery; intraoperative evaluation of middle ear anatomy during endos...

Electrocochleography (ECochG) measures inner ear potentials generated in response to acoustic stimulation of the ear. These reflect residual function cochlea. In cochlear implant candidates with hearing, electrode can directly measure ECochG responses during implantation process. Various authors have described ability monitor by continuous measurements surgery. The measurement signals surgery i...
