Introduction. Drug induced sleep endoscopy (DISE) or somnoscopy provides dynamic information about airway obstruction. This technique can be considered essential in the future for the therapeutic management of certain patients with obstructive sleep apnea (OSA). The aim of this study was to describe the main indications for DISE and the therapeutic approach carried out.

Material and Methods. A prospective observational study was conducted analyzing the characteristics of patients undergoing DISE as well as post-procedure management. Quantitative variables are described as mean ± standard deviation and categorical variables as absolute and relative frequencies.

Results. Between June 2018 and January 2021, DISE was performed on 50 patients in our center who were included in the study. The mean age was 48,18 years (SD 12). 22% (11) were women and 78% (39) men. Body mass index was 26,7 kg/m2 (SD 4.7). The mean Epworth was 8,8 (SD 6). The Apnea Hypopnea Index (AHI) was 42,8/hour (SD 39.8), with 52% (26) of the studied patients presenting severity. Poor response to CPAP was the most frequent indication (Figure 1). The otorhinolaryngology surgery followed by the indication for the use of the mandibular advancement device (MAD) and maxillomandibular advanced surgery were the attitudes most commonly adopted (Figure 2).

Conclusion. In certain patients with OSA with an intolerance to treatment or possible surgical indication, DISE is positioned as a useful procedure, facilitating a multilevel and multidisciplinary approach.
