IMPORTANCE OF BIFID MANDIBULAR CANAL IN IMPLANTOLOGY AND IN ORAL SURGERY: REVIEW OF THE LITERATURE AND REPORT OF THREE CASES
Abstract
The mandibular canal or the
inferior alveolar canal typically extends from the mandibular foramen to the mental foramen and includes the
inferior alveolar artery, vein and the inferior alveolar nerve. During
embryonic development three canals fuse to form a single canal. Failure of
these canals to fuse can explain presence of multiple canals in some
individuals. It is important to localize the course of the mandibular canal at
the site of implant placement as altered sensation of the inferior lip due to
inferior alveolar nerve injury. It is one of the most serious complication of
mandibular implant surgery. Also the
difficulty in performing mandibular anesthesia is the other problematic issue
for patients and the clinicians.
The purpose of this study is to call
attention to a rare anatomical variation. This case report reveals an unusual
variant of the bifid mandibular canals. Three new cases, two of which are in
the same family, have been presented.

Bifid Mandibuler Kanalin İmplantoloji ve Oral Cerrahideki Önemi: Üç Vaka Raporu ile Birlikte Literatürün Gözden Geçirilmesi
Abstract
Mandibuler kanal veya inferior alveoler kanal inferior
alveoler arter, ven ve inferior alveoler siniri içerecek şekilde tipik olarak
mandibuler foramenden mental foramene kadar uzanır. Emriyolojik gelişim
sırasında üç kanal tek bir kanal formu şeklinde füzyona uğrar. Bu kanalların
füzyona uğramasındaki başarısızlık bazı bireylerdeki çoklu kanalların varlığını
açıklayabilir. İnferior alveoler sinir yaralanması sebebiyle alt dudak duyu değişikliğinde
olduğu gibi implant yerleşim bölgesindeki mandibuler kanalın seyrinin
lokalizasyonu önemlidir. Bu, mandibuler implant cerrahisinin çok ciddi
komplikasyonundan biridir. Aynı zamanda mandibuler anestezi uygulamasındaki
zorluk, hastalar ve klinisyenler için başka bir problematik bir konudur.
Bu çalışmanın amacı nadir görülen bir anatomik varyasyona
dikkat çekmektir. Bu vaka raporu bifid
mandibuler kanalların alışılmamış varyantını ortaya çıkarmaktadır. Üç yeni
vaka, ikisi aynı aileden olmak üzere, sunulmuştur.
