Transsphenoidal surgery (TSS) of the hypothalamic-pituitary region is the approach of choice because of its lower morbidity compared to the transcranial approach. However, its results are highly variable and depend on many factors related to the tumor itself, to the medical team, and to technical issues. We review the situation of this procedure in a nationwide retrospective multicenter evaluation. Data were collected from centers participating in the TESSPAIN (TranssphEnoidal Surgery in SPAIN) registry, that included all TSS performed in each center during a 5-year period (2018-2022). Each center recorded the number of neurosurgeons performing TSS, the technical aspects, the number of procedures/year/surgeon, the pathology operated on, the goals set and their achievement, and the occurrence of long-term complications following the procedure. The 29 centers included performed a total of 2815 TSS procedures. Seventeen centers had more than one dedicated neurosurgeon, four of which had one neurosurgeon performing more than 75% of TSS. Twelve centers had one dedicated neurosurgeon (n:9) or two neurosurgeons who always operated together (n:3). An ENT surgeon always performed the nasal phase of the procedure in 21 of 29 centers, while it was performed by the dedicated neurosurgeon in five centers. In the remaining three centers the ENT surgeon was only required for very complex approaches. No one center averaged more than 40 TSS/year. Only six centers averaged more than 25 TSS/year. Only one center did not use an endoscopic approach. Extended approach to the cavernous sinus was reported by 27 centers. The most common pathology was clinically nonproducing pituitary adenomas (n=1421;50.5%), followed by producing pituitary adenomas (n: 911 (32.4%): 436 GH-producing, 323 Cushing´s disease, 127 prolactinomas and 25 TSH-secreting adenomas). 483 TSS (17.1%) were performed for the treatment of non-adenomatous tumors, usually with extrasellar extension including craniopharyngiomas, RCC, meningiomas, chordomas, and others. The percentage of TSS for nonproducing pituitary adenomas was negatively correlated with the total number of TSS (p:0.016), and the percentage of TSS for non-adenomatous tumors showed a positive correlation with the total number of TSS (p:0.012). TSS in Spain shows an inhomogeneous picture, with a high geographical dispersion and low surgical volume in each center, despite the recommendations of scientific societies. Almost all neurosurgeons use an endoscopic approach and perform a cavernous sinus approach. Centers with higher surgical volume have a higher percentage of TSS for non-adenomatous tumors, while centers with lower surgical volume operate more frequently on nonproducing pituitary adenomas.
