Sınıf III Ortognatik Cerrahi Hastalarında Yumuşak Doku ve Hava Yolu Değişimlerinin Değerlendirilmesi

Amaç: Kombine ortodontik tedavi ve ortognatik cerrahi yumuşak dokularda ve havayolunda değişikliklere neden olmakta olup, ameliyat sonrası oluşacak değişimlerin öngörülmesi tedavi planlaması açısından önemlidir. Bu çalışmanın amacı Sınıf III ortognatik cerrahi geçiren hastalarda sert doku, yumuşak doku ve havayolu değişimlerinin incelenmesidir. Gereç ve Yöntemler: Bu retrospektif çalışmaya, 18 Sınıf III hastanın pre-operatif ve post-operatif lateral sefalometrik radyografları dahil edilmiştir. Çalışmaya dahil edilen hastalarda maksiller gömme ve ilerletme, mandibular geri alma işlemleri uygulanmıştır. Hastalardan cerrahiden hemen önce(T1) ve cerrahiden en az 6 ay sonra(T2) alınan lateral sefalometrik radyografiler üzerinde yumuşak doku ölçümleri Dolphin (version 11.95,Dolphin Imaging&Management Solutions, Chatsworth, USA) programı, havayolu ölçümleri ise Planmeca Romexis (Planmeca Oy, Helsinki, Finland) yazılımı kullanılarak yapılmıştır. Elde edilen verilerin dağılımı Shapiro-Wilk testi ile incelenmiş olup, veriler paired t-testi ve Wilcoxon testi ile karşılaştırılmıştır. Bulgular: Hastaların T1 ve T2 dönemlerinde elde edilen verileri karşılaştırıldığında yumuşak dokuda Sn'-LLS/LLS-Me' değerinde ve E düzlemi-alt dudak mesafesinde istatistiksel olarak anlamlı artış, E düzlemi-üst dudak mesafesinde ise anlamlı azalma gözlenmiştir (p

Evaluation of Soft Tissue and Airway Changes in Patients Undergoing Combined Orthodontic and Orthognathic Surgery

Background: Combined orthodontic treatment and orthognathic surgery lead to changes in soft tissues and airway. Prediction of postoperative changes is important for treatment planning. The aim of this study was to investigate the changes in hard-soft tissue, and the airway in patients undergoing Class III orthognathic surgery. Methods: In this study, pre- and post-operative cephalometric films of 18 patients with Class III malocclusion were included. The maxillary impaction-advancement and mandibular setback were performed in these patients. Hard-soft tissue and airway measurements on lateral cephalometric radiographs which were taken immediately before surgery(T1) and at least 6 months after surgery(T2) were performed using Dolphin (version 11.95, Dolphin Imaging&Management Solutions, Chatsworth, USA) and Planmeca Romexis (Planmeca Oy, Helsinki, Finland) softwares, respectively. The data distribution was analyzed using the Shapiro Wilk test. Paired t-test and Wilcoxon test were used for statistical comparison. Results: A statistically significant increase in Sn'-LLS/LLS-Me' value and E plane-lower lip distance and a significant decrease in E-plane-upper lip distance were observed (p
