Allogeneic cartilage used for skull base plasty in children with primary intranasal encephalomeningocele associated with cerebrospinal fluid rhinorrhea.
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 deep frozen 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.
