Alkins RD, Newsted D, Nguyen P, et al. - This retrospective population-based cohort study was performed to determine preoperative patient demographics as well as comorbidities in relation with postsurgical complications after vestibular schwannoma surgery. Study population comprised 1,456 patients who had vestibular schwannoma surgery from April 1, 2002 to March 31, 2018 in Ontario, Canada. Hypertension (30.22%), diabetes (9.48%), asthma (13.53%), and chronic obstructive pulmonary disease (6.73%) were revealed as the most common comorbidities in this cohort. The most influential comorbidity was diabetes, which was found to be related to a higher risk of myocardial infarction, pneumonia, dysphagia, and meningitis. There was a negative association of translabyrinthine approach, vs the open craniotomy approach, with postoperative complications including pneumonia, urinary tract infection, dysphagia, and readmission. Overall, findings showed links between patient characteristics and postoperative results that can assist in preoperative decision-making as well as in counselling.
