To measure nasopharyngeal airway volume and compare it among different skeletal patterns. Forty five CBCT scans of patients between sixteen to twenty five years were used in the study. The nasopharyngeal airway was divided into upper, middle and lower segments. CBCT images were grouped into skeletal class I, class II and class III. There was highly significant difference in upper (p=0.001) and middle pharyngeal airway volume (p<0.001) among 3 skeletal groups. Lower pharyngeal airway volume was also statistically significant (p=0.051) among 3 groups. Total pharyngeal airway volume did not show any significant correlation. Nasopharyngeal airway volume seems to play a role in different skeletal patterns. Nasopharyngeal airway volume seems to play a role in different skeletal patterns. Cognitive problems in patients with obstructive sleep apnea have been suspected since the 1980s. Several studies have investigated different cognitive domains. A similar widespread survey has not been done in the Bulgarian population. This study aimed to evaluate global cognitive functioning and memory function in patients with obstructive sleep apnea and to examine the potential influence of comorbidities on cognitive functions. The study examined the neurocognitive profile of 103 consecutive patients newly diagnosed with OSA and 31 healthy controls. A list of inclusion and exclusion criteria was developed. Sleep breathing was examined in both groups. The other methods were a medical history of patients, clinical examination, neuropsychological assessment, statistical analysis. The study found that the global cognitive functioning of patients with OSA and the memory function was impaired. Short-term memory has been found affected predominantly. Only obesity was distinguished as a major factor relevant to
