Postoperative management after transsphenoidal surgery (TSS) is important; however, the guidelines for resuming daily activities after TSS are insufficient. This study aimed to examine the time to return to activities of daily living (ADL) after TSS for pituitary tumors. A 4-month prospective data collection was completed for 114 of 117 patients who underwent TSS for pituitary tumors from April to July 2021. The time when the patient returned to ADL after surgery was measured using the self-recording sheet. More than 97% and 92% of the patients returned within 1 month (median: within 7 days) for the elements of basic ADL and within 2 months (median: within 15 days) for the elements of instrumental ADL, excluding a few. Notably, 73.3% of patients returned to work within 4 months. The median time for the activities included 64 days for washing hair head down, 44 days for blowing nose, 59 days for lifting heavy objects, and 102 days for sexual activity. For patients who received extended-TSS or had postoperative problems, the time to return was delayed. Based on these results, it will be possible to provide practical information and guidelines on the time to return to ADL after TSS in pituitary tumor patients.
