Core Specializations
1. Pituitary Tumors (垂体瘤) - Premier Expertise
Dr. Zhao specializes in the comprehensive diagnosis and treatment of pituitary adenomas, the most common tumors of the sellar region.
Types of Pituitary Adenomas:
Functioning Adenomas (Hormone-Secreting):
- Prolactinomas: Most common pituitary tumor, secreting prolactin causing irregular periods, infertility, and galactorrhea in women; erectile dysfunction in men
- Growth Hormone-Secreting Adenomas: Causing acromegaly (enlarged hands, feet, facial features) in adults or gigantism in children
- ACTH-Secreting Adenomas: Causing Cushing's disease with weight gain, high blood pressure, diabetes, and characteristic appearance
- TSH-Secreting Adenomas: Rare tumors causing hyperthyroidism
- Gonadotroph Adenomas: Secreting FSH/LH, often clinically silent
Non-Functioning Adenomas:
- Null Cell Adenomas: Not secreting hormones, often discovered when large
- Silent Adenomas: Producing hormones without clinical symptoms
Classification by Size:
- Microadenomas (<10mm): Small tumors often causing hormonal symptoms
- Macroadenomas (≥10mm): Larger tumors causing mass effect on surrounding structures
- Giant Adenomas (≥40mm): Massive tumors requiring complex surgical approaches
Clinical Manifestations:
Hormonal Effects:
- Hyperprolactinemia symptoms (irregular periods, infertility, galactorrhea)
- Acromegaly features (enlarged extremities, facial changes, joint pain)
- Cushing's disease symptoms (central obesity, moon face, purple striae)
- Hypopituitarism (deficiency of pituitary hormones)
Mass Effect Symptoms:
- Visual Disturbances: Bitemporal hemianopsia (loss of peripheral vision) from optic chiasm compression
- Headaches: From tumor expansion and dural stretch
- Cranial Nerve Palsies: Double vision from cavernous sinus invasion
- Pituitary Apoplexy: Sudden hemorrhage into tumor causing severe headache, vision loss, and hormonal crisis
Comprehensive Diagnostic Approach:
- Hormonal Testing: Comprehensive pituitary hormone panel including prolactin, GH, IGF-1, ACTH, cortisol, TSH, FSH, LH, testosterone/estrogen
- Dynamic Testing: Stimulation and suppression tests (dexamethasone suppression, GH suppression, etc.)
- High-Resolution MRI: Dedicated pituitary protocol with thin cuts and contrast
- Visual Field Testing: Formal perimetry to document vision loss
- Ophthalmologic Examination: Assessing optic nerve and visual acuity
Treatment Approaches:
Medical Management:
- Dopamine Agonists: First-line for prolactinomas (cabergoline, bromocriptine)
- Somatostatin Analogs: For acromegaly (octreotide, lanreotide)
- GH Receptor Antagonists: Pegvisomant for resistant acromegaly
- Hormone Replacement: Treating hypopituitarism
Surgical Treatment:
- Transsphenoidal Surgery: Standard approach through nose and sphenoid sinus
- Endoscopic Endonasal Approach: Minimally invasive technique with superior visualization
- Microscopic Transsphenoidal: Traditional approach using operating microscope
- Transcranial Approach: For tumors with significant suprasellar extension
Radiation Therapy:
- Stereotactic Radiosurgery: Gamma Knife or CyberKnife for residual/recurrent tumors
- Fractionated Radiotherapy: For larger residual tumors
2. Endoscopic Transsphenoidal Surgery - Advanced Technique
Dr. Zhao is an expert in endoscopic endonasal surgery, the gold standard approach for most pituitary tumors.
Advantages of Endoscopic Approach:
- Superior Visualization: Wide-angle endoscopic view with high-definition optics
- Panoramic View: Seeing around corners and into recesses
- Minimally Invasive: No external incisions, operating through nostrils
- Better Tumor Removal: Higher gross total resection rates
- Lower Complications: Reduced CSF leak rates with modern techniques
- Faster Recovery: Most patients discharged in 2-4 days
- No Nasal Packing: Modern techniques avoid uncomfortable nasal packing
Surgical Technique:
- Binostril Approach: Working through both nostrils for optimal access
- Four-Hand Technique: Surgeon and assistant working together
- Neuronavigation: GPS-like guidance for precise localization
- Intraoperative MRI: Real-time imaging to confirm complete resection
- Skull Base Reconstruction: Multilayer closure to prevent CSF leak
- Vascularized Flap: Using nasal septal flap for large defects
Indications for Surgery:
- Non-functioning macroadenomas causing mass effect
- Functioning adenomas not controlled by medication
- Tumors causing vision loss
- Pituitary apoplexy with vision compromise
- Medication-resistant prolactinomas
- Acromegaly and Cushing's disease (surgery first-line)
3. Other Sellar Region Tumors (鞍区肿瘤)
Beyond pituitary adenomas, Dr. Zhao treats the full spectrum of sellar and parasellar masses.
Craniopharyngiomas:
- Adamantinomatous Type: Cystic tumors in children and adults
- Papillary Type: Solid tumors in adults
- Surgical Challenges: Adherence to hypothalamus, optic apparatus, and vessels
- Treatment Strategy: Balancing complete resection with preservation of function
Rathke's Cleft Cysts:
- Benign cystic lesions from embryonic remnant
- Often asymptomatic, discovered incidentally
- Surgery for symptomatic cysts causing headaches or vision loss
- Fenestration and drainage via endoscopic approach
Meningiomas:
- Tuberculum Sellae Meningiomas: Tumors compressing optic nerves
- Clinoid Meningiomas: Tumors involving anterior clinoid process
- Cavernous Sinus Meningiomas: Challenging tumors invading cavernous sinus
Other Lesions:
- Pituitary Carcinomas: Rare malignant pituitary tumors
- Metastases to Pituitary: Cancer spread from breast, lung, etc.
- Lymphocytic Hypophysitis: Autoimmune inflammation of pituitary
- Pituitary Abscesses: Infections requiring drainage
- Dermoid/Epidermoid Cysts: Congenital cystic lesions
- Chordomas: Skull base tumors involving clivus

- Replacing deficient hormones
- Managing diabetes insipidus
- Optimizing medical conditions

Frequently Asked Questions
Do all pituitary tumors require surgery?
No. Prolactinomas are usually treated with medication first. Small non-functioning adenomas may be observed. Surgery is recommended for tumors causing vision loss, uncontrolled hormone excess, or significant mass effect.
Will I need to take hormones after pituitary surgery?
Some patients require temporary or permanent hormone replacement depending on pre-operative function and extent of surgery. Dr. Zhao carefully monitors and manages hormonal needs.
What is recovery like after endoscopic pituitary surgery?
Hospital stay: 2-4 days. Most patients return to desk work in 2-3 weeks. Avoid heavy lifting for 4-6 weeks. No external incisions or visible scars. Nasal congestion resolves over 2-4 weeks.
Will my vision improve after surgery?
80-90% of patients with pre-operative vision loss experience improvement, often beginning within days of surgery. Earlier surgery provides better chance of complete recovery.
Can pituitary tumors come back?
Recurrence rates vary by tumor type: 10-20% for non-functioning adenomas, 10-30% for functioning adenomas over 10 years. Regular MRI surveillance detects recurrence early when most treatable.
How long should I stay in Shanghai for pituitary surgery?
Plan for 2-3 weeks: pre-operative evaluation and optimization (3-5 days), surgery and hospital stay (2-4 days), post-operative monitoring and follow-up (1-2 weeks) before traveling home.
