Pediatric skull base surgery. 2. Experience and outcomes in 55 patients.

In the second of these two articles, we will discuss our clinical experience with skull base surgery in the pediatric population. We present a retrospective analysis of 55 patients less than 16 years of age who underwent skull base surgical approaches at the Primary Children's Medical Center or the University of Utah Medical Center between January 1992 and April 1999. There were 30 boys and 25 girls (mean age 9.8 years). Patient follow-up averaged 58 months. Most patients had pathology that required either an anterior or anterolateral approach; 6 patients underwent a far-lateral or a transpetrosal exposure. Thirty-five procedures were performed by a neurosurgeon, a pediatric otolaryngologist performed 11 procedures, and 10 procedures were performed by both services together. Ninety-six percent of patients (n = 53) had a Glasgow Outcome Score of 4 or 5. Complications included 4 sustained cranial nerve palsies and 2 hemipareses. There were no CSF leaks, infections or deaths. Patients with sellar region pathology had a disproportionately higher incidence of postoperative morbidity. We conclude that in selected pediatric cases, skull base surgical techniques can be performed effectively and safely with the use of multidisciplinary teams. To implement these techniques, knowledge of their limitations and of the anatomical differences between the adult and pediatric cranial base is essential. Copyright 2003 S. Karger AG, Basel
