Evaluation of Nasal Airway Volume of Operated Unilateral Cleft Lip and Palate Patients Compared With Skeletal Class III Individuals

Abstract

Cleft lip and palate (CLP) patients have various problems with nasal anatomy beyond just oronasal separation. The alar base, concha, and septum are over impressed in these individuals. Additionally, skeletal class III deformity is seen. These conditions may limit nasal function. In our study, 15 unilateral patients with CLP older than 15 years (10 females, 5 males; mean age: 19.13) who had received surgery were included as the study group, and 15 participants with noncleft skeletal class III deformities were included as the control group (10 females, 5 males; mean age: 19.20). The individuals' nasal airway volumes (total/cleft side/noncleft side/control/ nasal passages) were examined and compared statistically. The results showed that the study group had significantly higher values in terms of total airway volume ( P < .05). Additionally, there were significant differences between the cleft side and noncleft side volumes, between the cleft side volumes and the volumes of the control group participants, and between the noncleft side volumes and the volumes of the control group participants ( P < .05). There was no difference between the groups in terms of nasopharyngeal ( P = .39) and nasal passage volumes ( P = .73). The results show there are some problems regarding nasal airway volume in patients with CLP, even when lip, palate, and alveolar cleft operations have been performed. The aim of this study was to evaluate differentiation of nasal airway volumes between unilateral patients with CLP and individuals with noncleft skeletal class III serving as the control group.
