Overview

Prospective cohort study investigates the impact of preoperative hydrocephalus on speech impairment in children following tumor surgery, indicating complex clinical management implications.

Key Points

This study aims to determine if preoperative hydrocephalus is an independent risk factor for postoperative speech impairment in children undergoing posterior fossa tumor surgery.
Included 800 children undergoing posterior fossa tumor surgery from 35 centers over 10 years.
Conducted speech and neurological assessments both before and after surgery.
Categorized preoperative hydrocephalus treatment as 'yes' or 'no' based on timing of alleviation.
Grouped outcomes of postoperative speech impairment into habitual, reduced speech, or mutism.
64% of children had preoperative hydrocephalus; absence was linked to lower postoperative speech impairment risk in initial analyses.
After adjustment, the association between preoperative hydrocephalus and postoperative speech impairment became non-significant.
Treatment for preoperative hydrocephalus was associated with increased risk of speech impairment in univariate analysis but not upon adjustment.
