    Purpose: To evaluate upper airway diameter differences before and after placement of custom made mandible protruding devices (MPD) in OSAS group and to compare with control group using computerized tomography. Methods: The OSAS group was composed of 15 patients aged from 25 to 45 years with mild-moderate OSAS and the control group included 15 healthy volunteers, aged from 25 years to 44 years. On coronal and sagittal reformated CT images, anteroposterior (AP) and lateral (LAT) diameters at three levels (passing through soft palate [level 1], 5 mm above uvula [level 2] and 1 cm above the tip of epiglottis [level 3]) were measured before and after MPD placement in both groups. Results: LAT diameters at level 1, level 2 and AP diameter at level 2 in OSAS group were significantly lower than in control group before MPD placement. Only LAT diameters at level 2 in OSAS group were significantly lower than in control group after MPD placement. When we compared upper airway diameters before and after placement of the MPD within each group, statistically significant increase in diameters at all levels were observed. Conclusion: MPD is a cheap, easily usable device providing increase in upper airway diameters. (C) 2014 European Association for Cranio-Maxillo-Facial Surgery. Published by Elsevier Ltd.

    Nasal septal body and inferior turbinate sizes differ in subjects grouped by sex and age
    (Int Rhinologic Soc, 2014) San, Turhan; Muluk, Nuray Bayar; Saylisoy, Suzan; Acar, Mustafa; Cingi, Cemal
    Objectives: To compare the size of the nasal septal body (SB) and inferior turbinate (IT) of subjects grouped by sex and age. Method: We measured SB and IT areas (in cm(2)) bilaterally in computed tomography (CT) sections of 150 paranasal sinuses from 72 males and 78 females. Results: The right and left SB areas were smaller in females than in males. In the <= 25-year-old group, the right IT (RIT) was significantly smaller in females than in males. In the 26-35 and 46-45 age groups, the right SB (RSB) was significantly smaller in females than in males. Conclusion: The nasal SB may play a role in nasal physiology similar to a turbinate and help support optimal airflow. The vascular and glandular structures of the SB should be investigated in detail, and minimal invasive procedures should be performed in nasal surgery to avoid damaging essential structures.
