The ideal treatment for diseases of the frontal sinus is one that will provide complete relief of symptoms, eradicate the underlying disease process, preserve the function of the sinus, and cause the least morbidity and the least cosmetic deformity. Despite more than two centuries since the description of the first procedure on the frontal sinus, the optimal procedure remains unclear. Although frontal sinus surgery makes up only a small portion of all paranasal sinus surgery, the literature is filled with publications on this subject. Ellis in 1954 stated that “surgical treatment of chronic frontal sinusitis is difficult, often unsatisfactory, and sometimes disastrous. The many surgical techniques available are expressions of our uncertainty and perhaps our failure”. The concept of FESS is the removal of tissue obstructing (OMC) and the facilitation of drainage while conserving the normal non-obstructing anatomy and mucous membrane. The rigid fiberoptic nasal telescope provides superb intra-operative visualization of the OMC, allowing the surgery to be focused precisely on the key areas. The image can be projected onto a television monitor through a small camera attached to the eyepiece of the endoscope. Micro debrides remove pathologic tissue while preserving normal mucosa
