Safety and Feasibility of Hypnosis-Induced Sleep Endoscopy in Obstructive Sleep Apnea Patients.

BACKGROUND

Hypnosis was never used in sleep endoscopy assessment of obstructive sleep apnea syndrome (OSAS). The aim of the study was to assess the feasibility, safety, and patient satisfaction of hypnosis-induced sleep endoscopy (HISE).

METHODS

From January to July 2021, 24 adults with moderate-to-severe OSAS at the polysomnography were included in the HISE protocol. The following outcomes were evaluated by the otolaryngologist and the hypnotherapist: safety, feasibility, and performance. The patient outcomes were assessed through a patient-reported outcome questionnaire assessing hypnosis acceptance, stress, anxiety, nasofibroscopy examination pain, and discomfort.

RESULTS

Twenty-three patients completed the evaluations (16 males). The mean age of patients was 50.8 years. The nasofibroscopy was well-tolerated with low levels of stress during the HISE. Otolaryngologist adequately completed the VOTE scoring in 22 patients (95.7%). Hypnosis was ineffective in one patient because he felt pain during the nasofibroscopy procedure due to an important septal deviation. The hypnotherapist reported adequate satisfaction outcomes, with better results for trance compliance compared to other steps. There were no adverse effects or complications. The percentage of snoring was negatively associated with the level of consciousness during hypnosis (p = 0.012). The easiness of nasofibroscopy was positively associated with the levels of muscle relaxation (p = 0.036) and consciousness (

CONCLUSION

HISE is an effective alternative approach for the work-up of OSAS. Future controlled studies are needed to compare HISE with drug-induced sleep endoscopy and assess the cost-effective outcomes of both approaches.
