Imaging of accessory mental foramen with cone-beam computerized tomography: two case reports

Öz

INTRODUCTION: Mental foramen is an important anatomic structure of the mandible. Mental foramen may be presented as more than one in some individuals and named as accessory mental foramen in such cases. Compared to mental foramen, accessory mental foramens are smaller in dimension and because of this, they may remain undetected with conventional imaging modalities. Cone-beam computerized tomography is a technique providing radiographic images of the three orthogonal planes of the maxillofacial region without magnification and distortion. Thus, compared with conventional radiographic techniques, it is more successful in the diagnosis of anatomic structures such as the accessory mental foramen.

CASE REPORT: Two female patients, one aged 27 and the other aged 59, presenting accessory mental foramen on cone-beam computerized tomography images on the left side of the mandible were presented in this article.

CONCLUSION: The visualization of accessory mental foramens with cone-beam computerized tomography has an important role in preventing complications like paresthesia and bleeding during surgical procedures.

Aksesuar mental foramenin konik-ışınlı bilgisayarlı tomografi ile görüntülenmesi: iki olgu bildirimi

Öz

TANITIM: Mental foramen mandibulanın önemli anatomik yapılarındandır. Bazı bireylerde mental foramen birden fazla sayıda olabilmekte ve böyle vakalarda aksesuar mental foramen olarak adlandırılmaktadır. Aksesuar mental foramenler, mental foramene kıyasla daha küçük boyutlarda olmalarından dolayı genellikle geleneksel yöntemlerle görüntüleme esnasında teşhis edilememektedir. Konik-ışınlı bilgisayarlı tomografi, maksillofasiyal bölgedeki yapıların radyografik görüntülerinin her üç ortogonal düzlemde magnifikasyonsuz ve distorsiyonsuz elde edilmesini sağlayan bir tekniktir. Bu nedenle geleneksel radyografik tekniklere göre aksesuar mental foramen gibi anatomik yapıların teşhisinde başarılıdır.

OLGU BİLDİRİMİ: Bu olgu bildiriminde birisi 27 diğeri 59 yaşında olan ve konik-ışınlı bilgisayarlı tomografi görüntülerinde mandibulanın sol tarafında aksesuar mental foramen izlenen iki kadın hasta rapor edilmektedir.

SONUÇ: Konik-ışınlı bilgisayarlı tomografi ile aksesuar mental foramenlerin görüntülenmesi, cerrahi işlemlere bağlı gelişebilecek parestezi ve kanama gibi komplikasyonların önlenmesinde önemli rol oynayacaktır.
