AI Article Synopsis
- The study aimed to analyze how lip pressure changes over time in skeletal Class III patients who underwent orthognathic surgery.
- It involved 63 patients, measuring their lip closing forces before and after surgery, and found notable differences between male and female outcomes.
- Results indicated that while lip closing forces increased for both genders post-surgery, they remained significantly lower compared to a control group even after one year.
Article Abstract
Objectives: The purpose of this study was to examine the changes with time in lip pressure after orthognathic surgery for skeletal Class III patients.
Study Design: The subjects consisted of 63 patients (32 female and 31 male) diagnosed with mandibular prognathism who underwent sagittal split ramus osteotomy with and without Le Fort I osteotomy. Maximum and minimum lip closing forces were measured with Lip De Cum(®). The changes with time were compared statistically.
Results: The maximum and minimum lip closing force increased time-dependently in men and women after surgery and there were significant differences between men and women with changes with time in the maximum lip closing force (p = 0.0086) and the minimum lip closing force (p = 0.0302). After 1 year, the Class III group maximum lip closing force was significantly smaller than the control group in both men (p < 0.0001) and women (p < 0.0001).
Conclusions: This study suggests that there was significant difference in over time in the lip closing force between men and women in Class III patients. Although the maximum lip closing force increased with time, it did not reach the level of the control group after 1 year.
