Effect of pre-operative mastoid pneumatisation on tympanoplasty success.

Objective: This study aimed to compare the effect of pneumatised and non-pneumatised mastoid on the success of tympanoplasty in terms of rate of graft uptake and air-bone gap improvement.

Method: A comprehensive electronic search of PubMed Medline, Scopus, Web of Science and Cochrane Library was conducted in August 2020 for articles from 1990 to 2020. Selected studies were published in the English language, were conducted on human patients, were concerned with evaluating pre-operative mastoid pneumatisation on tympanoplasty success, were not laboratory studies and were not opinion studies.

Evaluation of the advance off-stylet insertion technique and the cochlear insertion tool in temporal bones.

Objective: The concept and design of new cochlear implant electrodes is a challenging process. To evaluate new electrode designs, we present a study that uses a microgrinding procedure to evaluate damage to the microstructures of the cochlea resulting from the insertion procedure. In this study, we compared different insertion techniques with the Contour electrode with Softip for placement inside the cochlea and any resulting damage.
