What is the preferred surgical approach for benign pituitary neoplasms?

• A. Transsphenoidal resection
• B. Craniotomy
• C. Endovascular coiling
• D. Radiation therapy

Answer: (A)

Pituitary adenomas are benign tumors that grow in the sella turcica. The preferred surgical approach is transsphenoidal resection, which enters through the nasal cavity and sphenoid sinus to reach the sellar region. This route provides direct access to the tumor with minimal brain retraction, preserving surrounding brain tissue and often allowing complete or near-complete removal. It also tends to result in shorter recovery and fewer complications compared to opening the skull. This approach is especially effective for tumors confined to the sella or with limited suprasellar extension, where visualization of the tumor and the optic apparatus is excellent. In contrast, a craniotomy involves opening the skull and is more invasive, with higher morbidity and is typically reserved for tumors that extend laterally or inferiorly beyond what the transsphenoidal route can safely address. Endovascular coiling targets vascular lesions like aneurysms rather than pituitary tumors, so it isn’t used for this purpose. Radiation therapy can be used when surgery isn’t feasible or as adjuvant treatment, but it does not replace the surgical removal goal.
