OBJECTIVE: The aim of this study was to evaluate the frequency of anatomical variation in nasal cavity and paranasal sinuses by comparing a unilateral cleft lip and palate (UCLP) group with a non-syndromic control group using cone beam computed tomography (CBCT). SUBJECTS AND METHODS: This study included 24 UCLP patients in the UCLP group and 24 non-syndromic patients in the control group. Coronal CBCT images were taken in all patients and were evaluated for anatomical variation. The measurements obtained in this study were analysed using chi-square and Fisher's exact tests to compare the two groups statistically. RESULTS: In the UCLP group, there were statistically lower frequencies of pterygoid process pneumatisation (p <0.05), higher wing pneumatisation (p < 0.05), and sphenoid sinus over pneumatisation (p < 0.05), and statistically higher frequencies of anterior nasal septal deviation (p < 0.05) compared to the control group. CONCLUSION: A higher incidence of anterior nasal septal deviation was found in UCLP patients compared to the patients in the control group. It is likely that for this reason, UCLP patients might be predisposed to sinusitis. In UCLP patients, the incidence of neurovascular structures in the sphenoid sinus was lower than that in non-syndromic control patients (Tab. 1, Fig. 6, Ref. 33). Text in PDF www.elis.sk.

Objective: To analyze the article type, origin, main affiliation, number of publications, authors, and affiliations of six orthodontic journals during two intervals of 5 years each (2006-2010 and 2011-2015). Methods:In total, 4879 articles examined in this study were screened online at the individual journal's website. The types of articles and their authorship characteristics in the six orthodontic journals [three journals indexed by Science Citation Index (SCI) and the others indexed by Science Citation Index Expanded (SCIE)] were recorded. Parameters were tested using the Pearson chi-square for independence at a 0.05 level of significance.Results: Among all the article types, research articles were the most published in the orthodontic journals indexed by SCI and SCIE in the first (2006-2010; 88.1% and 77.6%, respectively) and second periods (2011-2015; 84.4% and 74.6%, respectively). In the first and second intervals, the European Union was the most common origin among articles accepted by the journals listed in SCI (30.1% and 29.2% respectively), whereas Asia/Oceania was the common origin among articles accepted by the journals listed in SCIE (44.1% and 43.4%, respectively). Conclusion:The articles published in the orthodontics journals listed under SCI and SCIE for 2006-2010 were significantly different in terms of numbers and characteristics.
