Analysis of aerosol production and aerosol dispersion during otologic surgery.

Background: As a respiratory disease, the transmission of Coronavirus disease (COVID-19) is mainly caused by small droplets and aerosols. Healthcare personnel are particularly exposed during otologic surgery given the continuity with the nasopharynx, where the viral load is high, and the use of high-speed instruments. The purpose of the present study is to test a model of droplet dispersion produced in the performance of a drilling procedure on human bone to provide information about its distribution and size of the deposit in similar conditions to those of an operating theatre, to design different preventive measures.

Use of pectoralis major myofascial flap on the prevention of pharyngocutaneous fístula in salvage laryngectomy after chemoradiotherapy.

Pharyngocutaneous fístula (PCF) is a major complication of salvage laryngectomies, mainly secondary to the effect of radiotherapy. Our main objective is to study the effect of pectoralis major myofascial flap (PMMF) on the prevention of PCF. We studied all total laryngectomies (TL) performed between 2001 and 2018, noting the use of previous chemoradiation, the type of suture and the use of flaps.
