Aims: This investigation was designed to evaluate upper airway spaces in patients with skeletal anteroposterior and vertical malocclusions. Methods and Materials: Ninty lateral cephalograms of patients were traced with Cl I, Cl II and Cl III malocclusions having normal bite, openbite and deepbite were traced. Hypopharyngeal, nasopharyngeal and oropharyngeal depths were measured considering a magnification of 1.1. Chisquare and ANOVA tests were used to analyse the data.

Results: Hypopharyngeal depth was found to be at 17.3±3.7mm in Cl I, 16.0±3 in Cl II and 16.7±4 in Cl III 17.4±0.1 in normal bite, 16.4±3.2 in openbite and 17.1±3.5 in deepbite. The mean oropharyngeal depth was 10.4±2.4 in ClI, 9.8±2.4 in ClII, 11.3±3.3mm in ClIII 10.9±3.1 in normal bite, 9.7±2 in openbite and 11±3.1mm in deepbite cases. Nasopharyngeal depth was found to be at 23.8±3.3 in ClI, 22:7±3.3 in Cl II: 21±4 mm in Cl III: 23±4.7 in normal bite, 22.1±3.5 in openbite and 22.4±3.1 in deepbite cases.

Conclusions: No significant difference was found between hypopharyngeal and oropharyngeal depths of three vertical and sagittal malocclusions. However, nasopharyngeal depth showed a significant difference between Cl II and Cl III malocclusions and also between Cl I and Cl III malocclusions (P<0.05). No significant difference was found between different groups in vertical malocclusions too.
