Le Fort I Osteotomisi Uygulanan Hastalarda Cinch Süturun Burun Yumuşak Dokusuna Etkisi

Abstract

Objective The purpose of this study was to evaluate the effect of cinch suture to prevent enlargement in the nasal tissue of 15 patients who maxillary advancement and impaction surgery with Lefort I osteotomy. Material and methods This study 15 orthognathic surgery patients (9 female, 6 male) underwent maxillary advancement and impaction surgery with Lefort I were included. While the average amount of advancement of the upper jaw is 5±1.55 mm; impaction amount is 2.5±0.83 mm. The patients were seperated into two groups, cinch suture performed (cinch suture group) and cinch suture not performed (control group). Before the operation the width lateral point of nose wings alar wideness (AW) and the joint that nose wings with face on base inferior subalar wideness (SAW) was assigned. Nasolabial angle (NLA) was determined on cephalometric radiographs taken before and after surgery. The mean follow-up period of the study was 7.2±0.8 months. All datas from this study was analized by ‘Statistical Packages for the Social Science’ statistical programme. Results After orthognatic surgery a significant increased on AW point observed on both group the cinch sütüre performed and the control group. While the difference between the groups in AG was not significant (p=0.463), the difference between the groups in SAG was significant (p=0.047). NLA measurements after orthognathic surgery decreased in the cinch suture group (p=0.182) and increased in the control group (p=0.865). Conclusion Despite cinch suture increased observed on both AW and SAW point after Lefort 1 osteotomy. We can say that while cinch suture finded beneficial to contain the enlargement of SAW, finded insufficient for prevention of enlargement AW. In our study, no significant effect of cinch suture on NLA was found. In contrast to cinch suture the risk of enlargement nasal wings should be considered and the patient should be informed before the operation.
