Abstract

Background: Mandibular anesthesia is a frequently preferred anesthesia technique in the restorative, pulpal and surgical treatments of milk molars and permanent molars, as well as in mandible fractures and all surgical interventions that involve the mandible. In this reason, localization differences of mandibular foramen should be taken into consideration while applying mandibular anesthesia technique in patients. The aim of this study is to evaluate the localization of the mandibular foramen in living adults with three-dimensional computed tomography images. Materials and Methods: The study was carried out retrospectively on the radiologic images of 200 randomly selected adult individuals who had computed tomography examination for paranasal sinus and/or head and neck pathologies. The closest vertical (A) and horizontal (C) distances from mandibular foramen to margins of mandibular ramus and total vertical (B) and horizontal (D) distances of mandibular ramus were measured bilaterally in the edandate and dendate individuals, and the A/B and C/D ratios were evaluated. Results: When the measurements of dentate and edentate mandibles were compared, a statistically significant difference was found in all parameters (A, B, C, D, A/B, C/D) and it was determined that the measurements of dentate mandibles were larger than those of edentate mandibles. When the mandibular measurements were compared according to the sides (left/right), the A and D measurements and AB ratio in the right dentate mandibles and the B, C, D measurements and AB, CD ratios in the right edentate mandibles were statistically significantly larger than the left side. When the measurements were compared by gender, the B, C, D measurements and AB ratio of male dentate mandibles were statistically significantly higher than females. Conclusion: It was determined that mandible measurements of dentate cases were larger than edentate mandible. Mandibular ramus can be asymmetrical and ramus morphometers may be affected by gender within the clinical syndromes. This study demonstrates that the anatomical landmarks determined to find the target area for nerve block and to determine the safety zone for the ramus osteotomy lines can vary depending on the presence of the teeth.

Özet

Amaç: Mandibular anestezi, süt ve kalıcı azı dişlerinin pulpa, restoratif ve cerrahi tedavilerinde, mandibula kırıklarında ve mandibulayı ilgilendiren tüm cerrahi girişimlerde sıklıkla tercih edilen bir anestezi tekniğidir. Bu nedenle hastalarda mandibular anestezi tekniği uygulanırken foramen mandibulae lokalizasyon farklılıkları dikkate alınmalıdır. Bu çalışmanın amacı, yaşayan erişkinlerde foramen mandibulaenin lokalizasyonunun üç boyutlu bilgisayarlı tomografi görüntüleri ile değerlendirmesidir. Gereç ve Yöntemler: Çalışma, paranazal sinüs ve/veya baş-boyun patolojileri için bilgisayarlı tomografi incelemesi yapılan rastgele seçilmiş 200 erişkin bireyin radyolojik görüntüleri üzerinde retrospektif olarak gerçekleştirildi. Foramen mandibulaedan ramus mandibulae kenarlarına en yakın dikey (A) ve yatay mesafeler (C) ve ramus mandibulaenın toplam dikey (B) ve yatay mesafeleri (D) dişli ve dişsiz bireylerde bilateral olarak ölçüldü. Bulgular: Dişli ve dişsiz mandibula ölçümleri karşılaştırıldığında, tüm parametrelerde (A, B, C, D, A/B, C/D) istatistiksel olarak anlamlı bir fark bulundu ve dişli mandibula ölçümlerinin dişsiz mandibulalara göre daha büyük olduğu belirlendi. Mandibular ölçümler laterilizasyona (sol/sağ) göre karşılaştırıldığında, sağ dişli mandibulada A ve D ölçümleri ve AB oranı ile sağ dişsiz mandibulada B, C, D ölçümleri ve AB, CD oranları istatistiksel olarak anlamlı derecede sol taraftan daha büyük bulundu. Ölçümler cinsiyete göre karşılaştırıldığında erkek dişli mandibulanın B, C, D ölçümleri ve AB oranı kadınlara göre istatistiksel olarak anlamlı derecede yüksekti.
