Endoscopic Sinus Surgery is a form of minimally invasive transnasal surgery to help drain and re-ventilate the paranasal sinuses.

Dr Stanley underwent an intensive hands-on instructional course by the founders of Endoscopic Sinus Surgery, the late Prof. Merserklinger and Prof. Heinz Stamberger at Graz Austria in 1991.

Since then, he developed a sub-specialty interest in Endoscopic Sinus Surgery, including its application in the treatment of skull base lesions. To date, Dr Stanley has performed several thousands of Endoscopic Sinus procedures.

Endoscopic Sinus Surgery is offered only after failure of maximal medical therapy. In children, endoscopic sinus surgery is done as a conservative approach in addition to adenoidectomy when indicated. Sinusitis in children is primarily a medical disease leaving Paediatric Endoscopic Sinus Surgery as a last resort. If performed, a mini-FESS (Functional Endoscopic Sinus Surgery) technique is performed to promote ventilation and drainage of the osteo-meteal complex.

Advanced Endoscopic Sinus Surgery is performed for anterior and central skull base lesions. Tumors of the pituary gland are routinely approached transnasally with an endoscope as shown below. A panoramic view of the surgical field is obtained. Post-operative tumour surveillance is possible in the clinic.
