Introduction Pituitary surgery is the standard treatment for Cushing’s disease, offering high success rates in well-defined cases. This article explores the surgical approach, challenges, and key considerations to optimize patient outcomes.

Surgical Approach 
For patients with clearly visualized adenomas on pituitary MRI, the preferred surgical technique is the mononostril endoscopic endonasal approach. This method achieves high rates of postoperative endocrine remission, ranging from 88% to 91% in major studies.

When an adenoma is not visible on preoperative MRI, expert teams often recommend pituitary gland exploration as a first-line treatment. This is typically preceded by inferior petrosal sinus or cavernous sinus sampling [3, 5]. The postoperative remission rate in such cases varies between 31% and 80%, depending on factors such as surgical expertise, adenoma identification during surgery, and the technique used in hypophysectomy.

Challenges in Pituitary Surgery for Cushing’s Disease
 The pituitary gland is situated in a complex anatomical region, surrounded by crucial neurological and vascular structures such as cranial nerves, carotid arteries, and cavernous sinuses. In Cushing’s disease patients, several anatomical factors pose additional challenges:

• Small sella turcica & poor pneumatization: These factors increase the risk of a lateral trajectory, potentially leading to carotid artery injury.
• Large cavernous and intercavernous sinuses: The presence of substantial venous bleeding can obscure the surgeon’s field of vision.
• Obesity and mucosa fragility: These conditions exacerbate intrasellar exploration challenges due to increased venous bleeding.
  

Optimizing Surgical Outcomes To enhance the success rate of pituitary surgery in Cushing’s disease, surgeons must prioritize clear visualization throughout the procedure. Specific surgical techniques and strategies can help optimize endocrine outcomes.

Drawing from our extensive experience with 683 Cushing’s patients, including 119 cases where no adenoma was identified on MRI, we outline key insights and surgical strategies developed by our senior neurosurgeons (S.G, B.B) to improve patient prognosis.

Conclusion Pituitary surgery remains the cornerstone treatment for Cushing’s disease. Despite the complexities involved, expert surgical techniques and strategic approaches significantly impact remission rates and patient recovery. Ongoing advancements in surgical methodologies continue to refine outcomes and improve the quality of life for affected individuals.
