Türk toplumunda mental sinir, mental lup ve insiziv kanalın retrospektif bir değerlendirmesi

Amaç: Oral bölgede yapılan cerrahi prosedürlerden sonra komplikasyonları önlemek için intraforaminal bölgenin 3-boyutlu radyografik değerlendirilmesi kritik önem taşımaktadır. Bu çalışmada konik ışınlı bilgisayarlı tomografi (KIBT) taraması ile foramen görülme sıklığı ve mental sinirde anterior loop varlığının belirlenmesi, insisiv sinir uzunluğunun retrospektif olarak değerlendirilmesi amaçlanmıştır. Gereç ve Yöntem: Bu retrospektif çalışma, 2017-2018 yılları arasında farklı nedenlerle CBCT görüntüleri kullanılan 176 hastayı içermektedir. Alınan görüntülerde mental foramenin (MF) şekli ve lokasyonu, mental sinir ve mandibular insisiv kanalın alveolar kreste, basise, bukkal ve lingual sınırlara olan uzaklığı, mandibular insisiv kanalın uzunluğu değerlendirildi. Bulgular: Tüm hastalar arasında %42,2 oranında anterior loop görüldü. MF lokalizasyon durumu cinsiyet bakımından bir farklılık görülmemiştir ve MF şekli açısından anlamlı bir fark bulunamamıştır (p> 0,05). Ortalama anterior loop mesafesi sağ tarafta 4,8±1,4 mm, sol tarafta 4,5 ± 1,2 mm bulunmuştur. Tüm görüntülerde mandibular insisiv kanal izlenmiştir. Ortalama mandibular insisiv kanal uzunluğu sağ tarafta 6,3±3,8 mm, sol tarafta 6±3,4 mm’dir. Sonuç: Klinisyenler intraforaminal bölgenin ameliyat öncesi değerlendirilmesinin öneminin farkında olmalıdır. Bu nedenle, CBCT görüntüleme tekniklerini kullanarak ameliyat öncesi planlama yapmakta fayda vardır.

A Retrospective Evaluation of Mental Nerve, Mental Loop, and Incisive Canal in Turkish Population

Objective: 3-dimensional radiographic evaluation of the intraforaminal area are crucial to prevent complications during surgical procedures. This study aimed retrospectively to determine incidence of different shapes of the foramen, and presence of the anterior loop with aid cone beam computed tomography (CBCT). Materials and Methods: This retrospective study was performed on 176 patients whose CBCT images indicated were used. The shape and location of the mental foramen; distance between the mental foramen (MF) and mandibular incisive canal (MIC); length of the alveolar crest, basis, buccal, and lingual sides; and MIC length were evaluated based on the images. Results: The anterior loop was observed in 42.2% of patients. No significant sex dependence was found in terms of MF localization status and MF shape (P > 0.05). The mean distance of the anterior loop was 4.8±1.4 mm on the right side and 4.5±1.2 mm on the left side. The MIC was observed in all images. The mean length of MIC was 6.3±3.8 mm on the right side and 6±3.4 mm on the left side. Conclusion: Clinicians should be aware of the importance of preoperative evaluation of the intraforaminal area. Therefore, it is beneficial to use CBCT imaging techniques for preoperative planning.
