ABSTRACT
OBJECTIVES: The purpose of present study is to assess the maxillary sinuses patients with COPD morphometrically and volumetrically using cone-beam computed tomography (CBCT) images and compared these findings according to in age and gender of control groups. METHODS: CBCT images of 80 individuals that exist from 40 patients with COPD and 40 healthy individuals (6 females, 34 males) in the tomography archive were retrospectively analyzed. The volume and surface area of maxillary sinuses in COPD and control group were measured by semi-automatic segmentation method and obtained findings were statistically examinated according to age, gender. RESULTS: The study was observed that there was no statistically significant difference between the right maxillary sinus area and the groups, but left maxillary sinus and total sinus area of COPD group were observed to be significantly lower than the control group (p < 0.05). Maxillary sinus volume was found to be statistically significantly lower in patients with COPD than in healthy controls (p < 0.05). CONCLUSIONS: CBCT is a practical and effective imaging method for the evaluation of maxillary sinuses. It is thought that inflammatory diseases that cause sinonasal changes such as COPD may affect maxillary sinus sizes.

OBJECTIVE: The purpose of this study was to evaluate the morphology of mandibular condyle using cone-beam computed tomography (CBCT) on coronal sections in a South-Eastern Anatolian population. METHODS: A total of 1820 joints in 910 subjects with age range of 18 to 86 years were examined retrospectively on CBCT images. The mandibular condylar morphology was examined in right and left sides on coronal sections and classified as convex, round, flat, and angled. In addition, condyle morphology was assessed according to age, gender, edentulism, Angle's classification. RESULTS: The study sample contained CBCT scans of 910 patients (50.3% female, 49.7% male) with a mean age of 42.31â±â15.74. Condylar morphologies were analyzed as convex in 40.5%, angled in 34.3%, flat in 15.5%, round in 9.6% of the cases. Condyle shape was found statistically related to group age, gender, edentulism (P <0.05). CONCLUSION: The findings suggest that mandibular condyle shape is associated with age, gender, and edentulism. CBCT may be considered as an appropriate imaging method for detection of condyle alterations of temporomandibular joints and it could provide early diagnosis of temporomandibular joint disorder.
