Concha nasalis superior'un bağlanma anomalisi: Bir olgu sunumu

Concha nasalis superior (CNS), labyrinthus ethmoidalis'in medial çıkıntısıdır. Meatus nasi superior'un çatısını oluşturur. Üç konkadan en küçük ve sığ olanıdır. CNS'nin lamina basalis'i koronal ve aksiyal olmak üzere iki parçaya sahiptir. Koronal parçası yukarıda kafa tabanına ve lateralde ise lamina papyracea'ya tutunur. Aksiyal parçası arkada sinus sphenoidalis'in ön yüzüne tutunurken, lateralde ise lamina papyracea'ya tutunur. Kronik baş ağrısı şikayetiyle kulak burun boğaz polikliniğine başvuran 52 yaşında, erkek hastaya çekilen bilgisayarlı tomografide, hastanın sol CNS'sinin bağlanma anomalisi tespit edilmiştir. Sol CNS'nin lamina basalisi'nin koronal parçası, kafatabanı yerine orbita medial duvarına tutunduğu belirlenmiştir. CNS'nin olağandan büyük olması, bağlanma anomalileri, pnömatizasyonu gibi anatomik varyasyonlar, klinisyenlerin tercih edecekleri cerrahi metodun belirlenmesinde oldukça önemlidir. Aynı zamanda olfaktor mukozayla kaplı oldukları için CNS ve concha nasalis suprema'nın gereksiz rezeksiyonlarından da kaçınılmalıdır.

The superior nasal turbinate (SNT) is the medial process of the ethmoidal labyrinth and describes as a small curved lamina. It roofs the superior meatus and it is the shortest and shallowest of the tree turbinates. There are two parts of the SNT which called coronal and axial part. The coronal part of the SNT basal lamella is attached superiorly to the skull base and laterally to the lamina papyracea, and thus can be used to identify these two vital structures. The axial part is attached posteriorly to the face of sphenoid and laterally to the lamina papyracea. A 52-year-old man was admitted to our hospital with chronic headache complaint. Attachment variation of the left SNT was determinate by computed tomography. Left SNT attach medial wall of the orbita. Anatomical variations of SNT like as huge concha, attachment variation or pneumatization is very important to prefer surgical method. Also, undesirable resection of the SNT and supreme nasal turbinate must be avoided; because of they are lined with olfactory neuroepithelium.
