Craniofacial Dermoids

The Presentation and Management of Nasal Dermoid

“…This theory explains the formation of superficial nasal dermoid, but does not account for a dermoid with intracranial extension. 1,6 In 1961, Littlewood 7 proposed the tri- laminar theory. Based on this explanation, the formation of nasal cartilaginous tissue is completed by the second month of gestation.…”

“…1,5,6,10,23 Pensler and colleagues 6 reviewed preoperative CT scans of 32 patients and concluded that an enlarged foramen cecum and bifid crista galli did not correlate with intracranial extension. However, they noted that a normal foramen cecum and crista galli rule out intracranial disease.…”

Nasal Dermal Sinus Cyst and Surgical Approach: Case Report

“…Pensler ve ark., çalışmalarında fistül açılma yerlerini; %29 glabella, %29 kolumella, %21 nazal dorsum ve %21 nazal tip olarak bildirilmişlerdir. 9 Lezyon uzanımı farklılık gösterir. Bradley; çalışmasında NDSK'lar %61 oranında yüzeyel nazal bölgede sınırlı iken, %16 nazal kartilajlara, %12 kribriform kemiğe, %10 nazal kemiğe, %1 etmoidlere uzanım tespit etmiştir.…”

“…10 Çe-şitli çalışmalarda intrakraniyal uzanım %10-45 arasında saptanmıştır. [9][10][11] Bizim olgumuzda NSDK yüzeyel nazal bölgede sınırlı ve fistül ağzı nazal tipin soluna lateralizeydi, intrakraniyal uzanım saptanmadı.…”

Dimensions and Ossification of the Normal Anterior Cranial Fossa in Children

“…Previous studies have looked at widening of the foramen cecum as an indirect marker of intracranial extension. 2,4 Pensler et al 8 reported 10 patients in whom an enlarged foramen cecum was taken as evidence of intracranial extension, with 7 of them having a bifid crista galli. At craniotomy, however, none of the patients were found to have intracranial lesions.…”
