OBJECTIVE: To analyze psychopathological outcome and health-related quality of life (QOL) for cohorts of patients undergoing transcranial or transnasal anterior skull base surgery.
METHODS: A prospective study of patients undergoing elective surgery for various entities of the anterior skull base was performed. Evaluation for depression (ADS-K score) and anxiety (PTSS, STAI-S, STAI-T, and ASI-3 scores) was done before surgery, at 3 and 12 months after surgery. The correlation between preoperative psychological burden and postoperative quality of life as measured by the SF-36 and EuroQol questionnaires was analyzed. Incidence and influence of these psychiatric comorbidities on clinical outcome were examined and compared between transnasal and transcranial subgroups.
RESULTS: We included 54 patients scheduled for surgery of a pituitary adenoma or meningioma of the anterior skull base between January 2013 and July 2017. Of these, a cohort of 40 (74.1%) completed follow-up interviews after 3 and 12 months. There were 60.0% female patients, median age was 57 years. 57.5% of patients had a meningioma and were operated transcranially, while 42.5% of patients received transnasal surgery for pituitary adenoma. The proportion of pathological anxiety scores significantly decreased from 75.0 to 45.0% (p = 0.002), without difference between transnasal and transcranial subgroups. After 3 months, mean EuroQol VAS score non-significantly increased by 0.07 (p = 0.236) across the entire cohort without significant difference between transcranial and transnasal subgroups (p = 0.478). The transnasal cohort tended to score higher in anxiety scores, whereas the transcranial cohort demonstrated higher depression scores without significant difference, respectively. The individually declared emotional burden significantly decreased from 6.7 to 4.0 on the ten-point Likert scale (p < 0.001) equally for both subgroups (transnasal, - 2.3; transcranial, - 3.0; p = 0.174). On last examination, about half of the patients in each subgroup (41.2% vs. 52.2%; p = 0.491) expressed a considerable recovery of preoperative bodily complaints such as headaches, dizziness, and unrest defined as a score of at least 8 on the Likert scaled item.
CONCLUSION: Both transnasal and transcranial approaches yield favorable postoperative QOL and psychopathological outcomes. The postoperative increase in QOL is partly influenced by preoperative expression of mental distress, which tends to resolve postoperatively.
