Morphological Analysis Of Obstructive Sleep Apnoea Patients Using Computed Tomography

1Department of Otorhinolaryngology, Adana City Training and Research Hospital, Adana, Turkey - ORCID ID: 0000-0001-7833-8421

Objective: The aim of the the study was to compare CT-obtained measures related to the cross-sectional area of the airway at various points (nasal valve, mid-nasal cavity, choanal, retro-lingual and retro-uvulal) in cases of obstructive sleep apnoea (OSA) with their values in nor­mal controls. Such abnormal values may act as markers of risk for OSA.

Methods: CT (computerised tomographic) imaging from 27 cases of OSA attending the Otorhinolaryngology Dept. of the Adana City Training and Research Hospital were evaluated retrospectively, alongside 9 normal con­trols.

Results: the means of the nasal valve and choanal cross sectional areas differed from the normal control means at the level of statistical significance (p=0.019 and p=0.012, respectively).

Conclusion: The authors hypothesize that the area of the nasal valve and the choanae have a bearing on the likeli­hood of developing OSA, but state that further research involving larger populations is needed to draw firm con­clusions.
