ABSTRACT
To assess the severity and evolution of sinonasal symptoms in patients following endoscopic
anterior skull base surgery to define the typical postoperative course. Design: Cross
sectional study. Participants include 69 patients who underwent endoscopic skull base
surgery by a dual surgeon team (otolaryngologist and neurosurgeon) from January 2008
to August 2009. Main outcome measures: Sinonasal Outcomes Test (SNOT)-20 survey scores
at preoperative and at three postoperative time points. An ordinal logistic regression
model was used to analyze the data, summarizing the relationship between the outcome
(SNOT score) and the predictor (time point) using an odds ratio. Scores for the symptoms
of need to blow nose, sneezing, runny nose, postnasal discharge, thick nasal discharge,
ear fullness, and facial pain showed significant worsening at the early postoperative
time point. These symptoms showed significant improvement over time; however, scores
for post nasal discharge remained high at the late time period compared with baseline.
All patients will experience considerable sinonasal symptoms following transnasal
endoscopic skull base surgery. Postnasal discharge and thick nasal discharge improve
significantly over time. Symptoms approach baseline by 6 to 9 months following surgery.
