Region	Japan

Condition
Condition	Obstructive Sleep Apnea Syndrome (OSAS)
Classification by specialty	Oto-rhino-laryngology Anesthesiology
Classification by malignancy	Others
Genomic information	NO

Objectives

Basic objectives -Others
Trial characteristics_1	Exploratory
Trial characteristics_2
Developmental phase	Not applicable

Assessment
Primary outcomes	Changes in number of apnea events per hour and oxygen desaturation index values during post-operative days 0-3 (POD0-3)
Key secondary outcomes	1) Pre-oprative detection of OSAS in patients with suspected OSAS and planned ESS; severity of pre-operatively diagnosed OSAS 2) Effectiveness of ESS on OSAS-related symptoms in patients with pre-operatively suspected SAS
