Abstract

<abstract> <title>Abstract</title> <p> <bold> <italic>Objective.</italic> </bold> The aim of this study was to compare the nasomaxillary complex in subjects with nasopharyngeal obstruction symptoms and the group with normal nasopharyngeal patency. <bold><italic>Materials and methods.</italic></bold> The study analyzed lateral cephalograms and dental plaster casts of 229 orthodontic subjects from the orthodontic clinic, i.e. 129 (56%) females and 100 (44%) males, age range of 6–30 years (mean age <bold><italic>=</italic></bold> 13.79). The analysis of radiographs and cephalometric measurements were performed using Orto-TestPor-ZPaluch software. The study population examined according to the stage of cervical vertebral maturation was divided into three sub<bold><italic>-</italic></bold>groups [<italic>the</italic> CVM A group consisted of 57 (24.9%) subjects, <italic>the</italic> CVM B group consisted of 85 (37.1%) subjects and <italic>the</italic> CVM C group consisted of 87 (38%) subjects]. <bold><italic>Results.</italic></bold> In the youngest age group with less than 50% airway patency, smaller values of SNA angle were observed together with diminished anterior palatal width compared with the non-obliterated group. The decrease in the area of the nasomaxillary complex and the decrease in posterior palatal width were observed in the oldest age group with less than 50% airway patency as compared to the subjects with normal patency. <bold><italic>Conclusions.</italic></bold> The nasomaxillary complex morphology in subjects with decreased nasopharyngeal patency pre<bold><italic>-</italic></bold>disposes to air flow impediment through nasal respiratory passage. Non-extraction treatment of the upper dental arch and possible maxillary expansion can be considered when orthodontic treatment is planned in subjects with decreased patency of < 50% and CVM A.</p> </abstract>
