Endonasal Endoscopic Surgery for Pediatric Anterior Cranial Fossa Encephaloceles: A Systematic Review

ABSTRACT Background Endoscopic endonasal skull base surgery (ESBS) is a well-established management strategy for anterior cranial fossa (ACF) encephaloceles in adults. However, its application to the pediatric population has not been evaluated in large-scale studies. This study systematically reviews the safety of ESBS for pediatric ACF encephaloceles. Methods Articles reporting on pediatric patients undergoing purely ESBS for encephaloceles were reviewed from three databases (PubMed, Scopus, and Cochrane Library). Main outcomes were post-operative cerebrospinal fluid (CSF) leak and other surgical complications. Results Twenty-three articles provided data on 110 eligible patients with a mean age of 4.3 years (range birth – 18 years). Intraoperative CSF leaks occurred in 18.5% of children while post-operative CSF leaks developed in 6.0% of cases. Rates of meningitis and hydrocephalus were each 3.7%. Other complications included alar collapse, nasal stenosis, transient diabetes insipidus, pneumonia, and neurologic injury, collectively occurring in 7.0% of cases. The rate of death was 4.8%. The average duration of follow-up was 25.3 months. Encephaloceles recurred in 5.2% of patients. Conclusions ESBS for pediatric ACF encephaloceles provides a relatively favorable risk-benefit profile, with a low rate of post-operative CSF leak, other surgical complications, and disease recurrence.
