Balance compensation after vestibular schwannoma (VS) surgery is under
the influence of specific preoperative patient and tumor characteristics.
Objective To prospectively identify potential prognostic factors for balance
recovery, we compared the respective influence of these preoperative
characteristics on balance compensation after VS surgery. Methods In 50 patients
scheduled for VS surgical ablation, we measured postural control before surgery
(BS), 8 (AS8) days after, and 90 (AS90) days after surgery. Based on factors
found previously in the literature, we evaluated age, body mass index and
preoperative physical activity (PA), tumor grade, vestibular status, and
preference for visual cues to control balance as potential prognostic factors
using stepwise multiple regression models. Results An asymmetric vestibular
function was the sole significant explanatory factor for impaired balance
performance BS, whereas the preoperative PA alone significantly contributed to
higher performance at AS8. An evaluation of patients' balance recovery over time
showed that PA and vestibular status were the 2 significant predictive factors
for short-term postural compensation (BS to AS8), whereas none of these
preoperative factors was significantly predictive for medium-term postoperative
postural recovery (AS8 to AS90). Conclusions We identified specific preoperative
patient and vestibular function characteristics that may predict postoperative
balance recovery after VS surgery. Better preoperative characterization of these
factors in each patient could inform more personalized presurgical and
postsurgical management, leading to a better, more rapid balance recovery,
earlier return to normal daily activities and work, improved quality of life, and
reduced medical and societal costs.
