“…In contrast to the self-limiting physiological CR, PCR is characterized by severe morphological changes of the condylar shape, a reduction of condylar volume and postoperative skeletal relapse (Chen et al 2013;Hoppenreijs et al 2013;Xi et al 2013). Although many previous studies have characterised the extent of PCR following mandibular advancement surgery, none of them have objectified the reduction in condylar volume and its relationship with postoperative skeletal relapse.…”

“…A major concern in the surgical advancement of the mandible is the potential postoperative relapse (Borstlap et al 2004;Chen et al 2013). Postoperative skeletal relapse is affected by bone movements at the osteotomy sites as well as by changes in the position and morphology of the condyles.…”

“…Skeletal relapse, as well as positional and dimensional changes of the condyles can be quantified in three dimensions (Chen et al 2013;Kim et al 2014). The application of a validated 3D condylar segmentation technique allows accurate volumetric measurements of condyles (Paniagua et al 2011;Xi et al 2013).…”

“…Such surgical instability could interfere with subsequent orthodontic treatment. Chen et al 26 reported that the changes in condylar position after SSRO were obvious 3 months after the surgery in mandibular retrusion patients. Kim et al 27 also suggested that condyles tended to move, and this could influence postsurgical relapse up to 6 months after surgery, according to their study using patients with mandibular prognathism.…”

Objective: To determine whether the condylar rotation is affected by asymmetric setback in patients undergoing sagittal split ramus osteotomy. Materials and Methods: Thirty patients who underwent bilateral sagittal split ramus osteotomy setback surgery were divided into the two groups, symmetric setback and asymmetric setback, according to the right/left difference of setback amount (,2.0, !2.0 mm). Condylar long axis changes were evaluated using the three-dimensional superimposition of before and immediately after surgery cone-beam computed tomography volume images. Evaluations were performed separately in lesser setback and greater setback side in patients undergoing asymmetric setback, whereas both side condyles were evaluated together in patients undergoing symmetric setback. Condylar axis changes on axial view were correlated with setback amount or right/left setback difference using Pearson correlation analysis. Results: In general, the condylar axis change occurred in a pattern of inward rotation. The condyles in patients undergoing symmetric setback showed 3.48 rotation in average. In case of asymmetric setback, the lesser setback side showed larger value (4.38) than the greater setback side (2.38) with a statistical significance. In the correlation analysis, setback amount showed no significant correlation with the condylar axis changes in both groups. However, correlation with right/left setback difference showed a positive correlation in lesser setback side of patients undergoing asymmetric setback. Conclusion: The findings of this study indicate that large amount of setback alone does not contribute to the change in condylar long axis, but asymmetric setback might cause a change in condylar long axis, particularly on the lesser setback side.

Yine tek çene mandibula ve çift çene operasyonları sonrası BSSRO'nin kondil pozisyonuna etkisinin değerlendirildiği diğer bir çalışmada her iki grupta da önemli bir değişiklik olmadığı rapor edilmiştir.…”

ÖZETKombine ortodontik ve cerrahi yaklaşım ciddi dentofasiyal deformitelerin düzeltilmesinde sıklıkla tercih edilen tedavi seçeneğidir. Bu deformitelerin tedavisi için geçmişten günümüze kadar birçok ortognatik cerrahi prosedür geliştirilmiştir. Son otuz yılda pek çok gelişme göstermelerine rağmen günümüzde bu tekniklerin komplikasyonları, karşılaşılan relaps oranları ve bunları azaltmak amacı ile yapılan araştırmalar devam etmektedir. Relapsın etyolojisi multifaktöriyeldir ve kondillerin düzgün pozisyonlandırılması, ilerletme miktarı, tek veya çift çene cerrahisi, yumuşak dokular ve kasların adaptasyonları, mandibuler plan açısı, geriye kalan büyüme potansiyeli ve operasyon öncesi hasta yaşı ve parafonksiyonel alışkanlıklar gibi faktörlere bağlıdır. Ortognatik cerrahi sonrası relaps; dişsel ve iskeletsel olarak meydana gelmektedir. İskeletsel relapsla daha çok karşılaşılmakta ve relaps oranları uygulanan cerrahi prosedürlerin tipine, hareketin yönüne ve hareket miktarına göre değişiklik göstermektedir. Ortognatik cerrahide relapsı en aza indirmek için cerrahi öncesi hastanın özelliklerinin iyi değerlendirilmesi, iyi bir tedavi planı, cerrahi öncesi başarılı bir ortodontik tedavi, uygun ve başarılı cerrahi teknik dikkat edilmesi gereken hususlardır. Anahtar Kelimeler: Ortognatik cerrahi, relaps Abstract A combined orthodontic and surgical approach is often the treatment of choice for the correction of severe dentofacial deformities. Numerous orthognathic surgical procedures have been developed for this treatment for many years. Although many improvement of all the techniques for the last thirty years nowadays investigations to decrease complications and relapse rates still continue. The etiology of relapse is multifactorial, involving the proper positioning of the condyles, the amount of advancement, single or two jaws surgeries, adaptation of the soft tissue and muscles
