Abstract
Objective
To evaluate swallowing in patients who underwent CO2 LASER Partial Epiglottectomy
(CO2-LPE) for Obstructive Sleep Apnea Syndrome and to assess the risk of aspiration
with this technique.
Material & Methods
Chart review of adult patients who underwent CO2-LPE between 2016 and 2020, in a secondary
care hospital. Patients underwent surgery for OSAS, in accordance to Drug Induced
Sleep Endoscopy findings and an objective swallowing evaluation was done at least
6 months after surgery. Eating Assessment Tool (EAT-10) questionnaire was applied
and Volume-Viscosity Swallow Test (V-VST) and Fiberoptic Endoscopic Evaluation of
Swallowing (FEES) were performed. Dysphagia was classified according to Dysphagia Outcome Severity Scale (DOSS).
Results
Eight patients were included in the study. The mean time between surgery and the swallowing
evaluation was 50 (±13,2) months. Only 3 patients presented ≥ 3 points on EAT-10 questionnaire.
Two patients presented signs of decreased efficacy of swallowing (piecemeal deglutition)
but none had a decrease in safety, according to V-VST. Although 50% of the patients
presented some pharyngeal residue on FEES, it was classified as trace to mild in most
of the cases. No evidence of penetration or aspiration was identified (DOSS ≥ 6 in
all patients).
Conclusion
The CO2-LPE is a potential treatment for OSAS patients with epiglottic collapse and
no evidence of swallowing safety compromise was found.
