Combined endonasal and percutaneous endoscopic approach to Pott's puffy tumour.

The most favourable management of frontal sinus disease and its complications involves the choice of the least invasive operative technique likely to eradicate the disease process. With the introduction of endonasal endoscopic surgery, examination of the frontal recess and removal of obstructive ethmoidal cells or diseased mucosa becomes feasible. Percutaneous frontal sinus endoscopy facilitates sinus irrigation, thorough inspection of the frontal sinus, removal of diseased mucosa within the frontal sinus, and evacuation of subperiosteal abscesses. Six cases of Pott's puffy tumour secondary to frontal sinusitis treated by combined endonasal and percutaneous endoscopic surgery are presented. CT scan is diagnostic for associated complication and underlying pathology. Complications are minimal. Combined endonasal and percutaneous endoscopic surgery is a good approach which can be carried out for the treatment of frontal sinus diseases and its complications.
