Introduction
If a pituitary tumor is treated via minimally invasive surgery, pain may persist for one to two weeks; this is primarily because the incision is small and postoperative recovery is relatively rapid. In contrast, if a craniotomy is performed, the overall recovery period tends to be longer, with pain potentially lasting two to four weeks. During this time, careful wound care is essential to prevent infection.
The duration of postoperative headache following pituitary tumor surgery depends on the surgical approach employed; common procedures include minimally invasive surgery and craniotomy.
1. Minimally Invasive Surgery
Pituitary tumors primarily arise from the neurohypophysis, adenohypophysis, or residual squamous epithelial cells of the embryonic craniopharyngeal duct. If the tumor is small and asymptomatic—and if the patient meets the criteria for minimally invasive surgery—this approach is typically selected. Following minimally invasive surgery, pain usually persists for approximately one to two weeks. This relatively short duration reflects the smaller incision size and faster postoperative recovery associated with this technique.
2. Craniotomy
When the pituitary tumor is large and exhibits significant invasion into surrounding tissues, complete resection via minimally invasive techniques may be difficult or impossible; in such cases, craniotomy is more appropriate. Due to the larger surgical wound, recovery takes longer after craniotomy, and postoperative pain may persist for approximately two to four weeks. During this period, careful wound care and infection prevention are essential.
