Abstract (EN): Purpose Obstructive sleep apnea syndrome (OSAS) is characterized by upper airway inflammation. The aim of this study was to characterize thermal profile of the antero-cervical region in OSAS patients through medical thermal imaging and to compare the respective subjects with non-OSAS individuals. Methods Image capture followed the Glamorgan Protocol. A dynamic thermographic examination of the anterior cervical region (at baseline and after a cold stimulus) was conducted in 26 patients diagnosed with overnight polysomnography (PSG). PSG results stratified the subjects into OSAS and non-OSAS groups and their thermograms were compared. Results Eleven non-OSAS and 15 OSAS subjects were evaluated. Antero-cervical right side (RS) temperature was higher in OSAS group at baseline (p = 0.014). Right side index (RSI) temperature-the difference between RS and submental region, considered as control-was lower in OSAS subjects at baseline (p = 0.020) and 10 min after the cold stimuli was applied (p = 0.008), indicating higher absolute temperatures in this group. Left side index (LSI) was also lower at 10 min in OSAS group (p = 0.021). Statistical correlation was found between apnea-hypopnea index and RS at baseline (r = 0.424, p = 0.031) and at 10 min (r = 0.403, p = 0.041) and RSI at baseline (r = -0.458, p = 0.019) and 10 min after cold provocation was applied (r = -0.435, p = 0.025). Conclusions OSAS patients have shown higher antero-cervical temperatures compared with non-OSAS counterparts and temperature was associated with severity of the condition. Medical thermography may be a suitable tool in the setting of OSAS suspicion.
