FESS – As the name suggests it is a surgery performed with an endoscope to restore functioning of sinuses (in those patients suffering from Chronic Sinusitis, Allergic Fungal Sinusitis, Sinonasal Polyps, Tumors etc).
The advantages of use of the endoscopes are better illumination, magnification, visualization which allows the surgeon for complete disease clearance.
As it is a minimally invasive technique it scores over the traditional, conventional surgeries as there is less morbidity, faster healing thereby leading to early resumption of routine activities.
