Introduction and objectives:

The diagnostic test of COVID-19 with the highest sensitivity is a nasopharyngeal sample using a swab for subsequent study using RT-PCR. The objective of our work is to explain in detail the most appropriate way to perform this technique.

Material and methods:

We present a retrospective study of 17 patients. Finally, two patients were excluded. The patients were 34-72 years old. A Polysomnography was done, and hypopneaapnea index was 7,32±8,71.

Discussion and conclusions:

This a secure technique and can be reproduced in all ENT services. DISE less us individualize chirurgical treatment and avoid us unnecessary patients' operations.
