ANATOMİK BİR VARYASYON: AKSESUAR MENTAL FORAMEN

Aksesuar mental foramen nadir görülen bir anatomik varyasyondur. Bulunma sıklığı çeşitli ırklarda farklılık göstermekle beraber, literatüre göre %1.4 ile %12.5 arasında değişmektedir. 6 yaşında erkek hastanın 3D BTsinde sağ mental foramenin anteriorunda, asıl mental foramene göre daha küçük ve süt kaninin kökünün mesiali hizasında, alveol kretin tepesine daha yakın olmak üzere konumlanmış bir aksesuar mental foramen tespit edildi. Dişhekimliği kliniklerinde teşhis ve tedavi prosedürlerinde, özellikle implant yerleştirilmesi gibi maksillofasiyal cerrahi uygulamalarında, pre-intra-postoperatif başarı açısından olası mental foramenin tespiti ve korunması son derece önemlidir.

AN ANATOMICAL VARIATION: ACCESSORY MENTAL FORAMEN

Accessory mental foramen is a rare anatomical variation. Prevalence may alter in different ethnicities, and ranges between1.4% and 12.5% according to the literature. An accessory mental foramen smaller than the primary mental foramen, localizedmesially and nearer to the tip of the alveolar crest than the primary foramen was seen under the decidious canine’s root in a6-year-old male’s 3D-CT images. During diagnostic and treatment procedures particularly the maxillofacial surgery practisessuch as implant placement, it has a vital importance to localize and protect the mental foramen for pre-intra and postoperativesuccess in dental clinics.
