A Case of Endoscopic Sinus Surgery for Lateral Frontal Sinusitis

ABSTRACT

Frontal sinusitis can cause an intractable frontal headache. Frequently, the external approach is performed for a lesion located in the lateral aspect of the frontal sinus. This area is considered to be "out of reach" for standard endoscopic instruments. However, problems such as scars can be a serious handicap of the external approach for patients with cosmetic concerns. We experienced a case of lateral frontal sinusitis associated with an intractable frontal headache, which was successfully treated via endoscopic sinus surgery aided by sagittal CT and intraoperative C-arm using K-wire instead of the external approach.
