Abstract
Three children with primary intranasal encephalomeningocele associated with cerebrospinal fluid rhinorrhea were operated on at the Department of Neurosurgery, Hradec Králové. In two children, aged 4 and 9.5 years, freeze-dried allogeneic costal cartilage was glued into the skull base defect. This plugging was covered up with deepfrozen allogeneic fascia lata. In the third child, an only 1-year-old boy, after transection of the neck of the encephalomeningocele freeze-dried allogeneic dura mater was glued on extradurally and deep-frozen allogeneic fascia lata applied intradurally. The cerebrospinal fluid rhinorrhea ceased immediately after surgery. Spontaneous atrophy of the intranasal portion of the encephalomeningocele was demonstrated respectively 11, 1, and 7 years postoperatively on computed tomography. To evaluate cartilage healing histologically, the extracted allogeneic cartilage used for orbital roof plasty after 4 months was examined. The extent of spotty regressions represented about 7% of the tissue volume. It is stressed that, once diagnosed, intranasal encephalomeningocele associated with cerebrospinal fluid rhinorrhea should be operated on for prevention of meningitis as soon as possible.
