Aim: Bilateral sagittal split ramus osteotomy (BSSRO) is commonly used to correct mandibular deformities. The first cut for this osteotomy is performed on the medial aspect above the lingula. During this procedure; The most feared intraoperative complication, the undesired fracture. Most of the BSSRO complications consist of condyle fracture or buccal/lingual plate fracture. The aim of this study was to determined the distance between the lingula and the sigmoid notch which is a surgical importance for BSSRO. Material and Methods: This retrospective study composed of the cone beam computed tomography images that were obtained at the our clinic. The sample compromised 70 patients (32 males and 38 females, with an age range of 12 to 28 years). The perpendicular distance between the fixed plane and upper limit of lingula was measured. The sample comprised 70 subjects (32 males and 38 females, with an age range of 12 to 28 years). The obtained data were statistically evaluated. Results: The minimum distance of the between fixed plane passing from sigmoid notch with lingula was found as a minimum of 4.80mm and a maximum of 19.20mm (mean±std. dev.= 11.99mm±2.40, n=140). The right and left side measurement ranged from 4.80mm to 16.4mm (mean±std. dev=11.34mm±2.26, n=70) and 7.72mm to 19.20mm (mean±std. dev.= 12.64mm±2.39, n=70), respectively. Conclusion: The findings obtained in this study provide a guideline for surgeons performing BSSRO on young populations in Turkey. Pre-procedural three-dimensional evaluation provides valuable information to prevent undesirable fractures.

Bu osteotomi icin ilk kesi lingula uzerinden gecen bir hat uzerinde gerceklestirilir. Bu cerrahi sirasinda en korkulan intraoperatif komplikasyon istenmeyen kirik olusumudur. Operasyon esnasinda hem proksimal hem de distal segmentlerde kirik olusabilir. Bu calismanin amaci, guvenli bir bilateral sagittal split ramus osteotomisi icin cerrahi onemi olan lingula ve sigmoid centik arasindaki mesafeyi belirlemektir. Gerec ve Yontem: Bu retrospektif calisma, klinigimizde cesitli dental sebeplerle elde edilen konik isinli bilgisayarli tomografi goruntuleri uzerinde gerceklestirildi. Aksiyel duzlem, sigmoid centikten gececek sekilde konumlandirilarak, olusturulan sabit duzlem ile lingula ust siniri arasindaki dikey mesafe olculdu. Orneklem 70 kisinin (12-28 yas araliginda, 32 erkek, 38 kadin) verilerini icermekteydi. Veriler istatistiksel olarak degerlendirildi. Bulgular: Minimum mesafe 4.8 mm maksimum mesafe 19 mm olarak bulundu (ort±std sapma=11,99 mm±2.40, n=140). Sag ve sol taraf olcumleri sirasiyla 4.80 mm’den16.4mm’ye (ort±std. sapma= 11.34mm± 2.26, n=70), 7.72mm’den 19.20mm’ye (std. dev.= 12.64mm±2.39, n=70) degismekteydi. Sonuc : Bu calismada elde edilen bulgular genc Turk populasyonuna bilateral sagittal split ramus osteotomisi icin cerrahlara bir rehber olabilir. Prosedur oncesi uc boyutlu degerlendirme, istenmeyen frakturlerin onlenmesinde degerli bilgiler saglar. Anahtar Kelimeler: Horizontal Ramus Kesisi, KIBT, Sagittal Split Osteotomisi

Osteosarcoma comprises 23% of head and neck malignancies. Studies show that 6% to 9% of all osteosarcomas are seen in the maxilla and mandible. In osteosarcoma in jaws, the survival rate is higher and the risk of metastasis is lower compared to osteosarcoma in the extremities. The gold standard in osteosarcoma diagnosis is computed tomography and magnetic resonance imaging. ‘Sunray appearance’ is a common radiologic finding of sarcomas. A 29-year-old male patient received to our clinic with pain and swelling in the right mandible. Extra-oral examination revealed that facial asymmetry and significant swelling in the right mandible. On the cone beam computerized tomography examination, a lytic, mixed lesion area was observed with conical shaped root resorption around the mandibular right second premolar and first molar tooth roots. Ultrasound examination revealed that thinning, expansion, and erosion of the buccal cortical bone and 'sunray appearance' in the mandible. Cone beam computerized tomography and ultrasound have become an important diagnostic technique for the evaluation of maxillofacial pathologies. Ultrasound imaging is a rapid technique that aids in the early and differential diagnosis of pathologies. Sunray appearance is a pathognomic finding for osteosarcoma. In present case report, diagnostic ultrasonography is the second case in the literature used in osteosarcoma of the mandible.Keywords: Cone beam computed tomography, jaw osteosarcoma, sunray, ultrasonographyMANDİBULA OSTEOSARKOMUNDA ULTRASONOGRAFİDE GÜNEŞ IŞINI GÖRÜNÜMÜ: NADİR BİR OLGU SUNUMUÖZOsteosarkom, baş ve boyun malignitelerinin % 23'ünü oluşturur. Çalışmalar, tüm osteosarkomların % 6 ila % 9'unun maksilla ve mandibulada görüldüğünü göstermektedir. Çenelerde görülen osteosarkomda sağkalım oranı daha yüksektir ve metastaz riski ekstremitelerde görülen osteosarkom ile karşılaştırıldığında daha düşüktür. Osteosarkom tanısında altın standart bilgisayarlı tomografi ve manyetik rezonans görüntülemedir. Radyografik olarak, “güneş ışını görünümü” sarkomların yaygın bir bulgusudur. 29 yaşında erkek hasta kliniğimize sağ mandibulada ağrı ve şişlik ile başvurdu. Ekstraoral muayenede, yüz asimetrisi ve sağ mandibular çenede belirgin şişlik gözlendi. Konik ışınlı bilgisayarlı tomografi incelemesinde, mandibular sağ ikinci premolar ve birinci molar diş kökleri çevresinde konik şekilli kök rezorpsiyonu ile litik, karışık bir lezyon alanı gözlenmiştir. Ultrasonografide ise, mandibulada bukkal korteksin kemik incelmesi, erozyonu ve “güneş ışını görünümü” gözlenmiştir. Konik ışınlı bilgisayarlı tomografi ve ultrasonografi, maksillofasiyal patolojilerin değerlendirilmesi için önemli bir tanı tekniği haline gelmiştir. Ultrasonografi, patolojilerin erken ve ayırıcı tanısına yardımcı olan hızlı bir tekniktir. Güneş ışını görünümü osteosarkom için patognomik bir bulgudur.
