SLIP-endoscopy in the diagnosis of obstructive sleep apnoea

Objective: the relationship between the clinical manifestations of snoring and obstructive sleep apnea syndrome (OSAS) and the functional characteristics of the upper respiratory tract (URP). Materials and methods: During 2021-2022, 20 patients with snoring and OSA underwent sleep endoscopy. Slip endoscopy data were evaluated according to the NOHL and VOTE systems. Results: According to the VOTE system, obstruction at the level of the soft palate was noted in 15 patients, and in 3 patients it was total. Anteroposterior (n=10), concentric (n=3), lateral (n=3) narrowing (by shape) was found at the level of the soft palate. At the level of the root of the tongue in 15 patients there was no obstruction, in 1 it was total, in 4 it was partial. In 15 patients, the level of the epiglottis remained intact, in 1 there was total obstruction, in 4 - partial obstruction. Conclusion: The correlation between the degree of severity of OSA and the level and form of narrowing was noted. For OSAS of a mild degree, the most characteristic is an isolated anteroposterior narrowing only at the level of the soft palate. With OSAS of moderate degree, the combination of anteroposterior obstruction only at the level of the soft palate and partial obstruction only at the level of the root of the tongue is most common. Concentric narrowing only at the level of the soft palate and total only at the level of the root of the tongue is characteristic of severe OSAS.
