Bottom Line: In class III malocclusion patients, decrease in facial angle, convexity angle, mentolabial angle, and increase in upper lip protrusion had the most positive impact on QoL.Decrease in facial angle and increase in upper lip protrusion were correlated positively with satisfaction questionnaires.In class II malocclusion patients, increase in convexity angle, facial angle and mentolabial angle had the most positive impact on satisfaction and QoL.

ABSTRACT

Objectives: This study was designed to assess the relationship between postsurgical cephalometric changes and quality of life and satisfaction after orthognathic surgery.

Material and methods: Sample size consisted of 30 patients with class III and 25 patients with class II malocclusion treated with bilateral sagittal split osteotomy and Le Fort I osteotomy. Profile convexity, lower facial height proportion, lip position and length, nose, and chin position were measured on pre and post-treatment cephalograms. To assess the patients' satisfaction and quality of life (QoL) after surgery, the questionnaire of the Rustemeyer's study and Oral Health Impact Profile (OHIP) questionnaire were used, respectively. The paired-sample t-test, Spearman correlation analysis and Pearson correlation analysis was used in SPSS statistical software.

Results: In class III malocclusion patients, decrease in facial angle, convexity angle, mentolabial angle, and increase in upper lip protrusion had the most positive impact on QoL. Decrease in facial angle and increase in upper lip protrusion were correlated positively with satisfaction questionnaires. In class II malocclusion patients, increase in convexity angle, facial angle and mentolabial angle had the most positive impact on satisfaction and QoL.

Conclusions: Consideration both subjective and objective parameters affecting on the patients' satisfaction and their quality of life is essential.

Soft and hard tissue measurement: 1 = Nasolabial angle; 2 = Facial angle; 3 = Mentolabial angle; 4 = Convexity angle; 5 = Upper lip protrusion; 6 = Lower lip protrusion; 7 = Upper lip length; 8 = Lower lip length.

Mentions: Pre- and postsurgical cephalograms were taken with head in natural position, teeth in centric occlusion, and lips in response. The distance between film and X-ray tube was 150 cm and the distance between the film and mid sagittal plane of the patient’s head was 18 cm. The horizontal reference line used in this study was the line with 7 degrees of difference to the sella-nasion line. Soft and hard tissue landmarks were shown in Figure 1. Seven angular (SNA, SNB, ANB, nasolabial angle, facial angle, convexity angle, mentolabial angle), 5 linear (upper lip length, lower lip length, upper lip protrusion, lower lip protrusion, Wits appraisal) and one ratio-related (Jaraback index) measurements were used to assess dento-skeletal characteristics on pre- and postsurgical cephalograms of each patient (Figure 2). Pre- and postsurgical radiographs used in this study were taken when no orthodontic appliances were present on the teeth in order to avoid misinterpretations resulting from presence of brackets, especially in lips.
