Summery Sinoliths are the calcification in the sinuses. Frontal sinoliths are very rare especially. We report a case of sinolith in the frontal sinus of a 39-year-old man with eosinophilic sinusitis. His sinusitis was resistant to conservative therapy. X-ray and computed tomographic scanning revealed the high-density mass in the left frontal sinus. He was operated with endoscopic surgery with extra-nasal surgery and finally removed the whole calcified lesion. There was no evidence of foreign bodies or fungus. In such case, the sinoliths may be caused by long-time inflammation. It was considered the treatment of sinolith needs to completely removal the calcification completely including ESS with extra-nasal surgery and to treat chronic inflammation. Introduction Sinolith is a mineralized masses and calculus formation in paranasal sinus. It has been also known as antrolith, rhinolith, antral calculi, antral stone, or antral rhinolith. It is caused chronic infection, foreign body or fungus. Sinoliliths are rarely located in the frontal sinus. We …show more content…
The surgical removal of calcification is the treatment of sinoliths, the prognosis is good after remove the calcification. And the treatment of eosinophilic sinutis is as important as the remove the stone for the improvement of the symptoms and the reccurence preservation. We performed the ESS and steroid treatment for eosinophilic sinutis and the extranasal surgery for frontal sinuths. The endscopic sinus surgery is general for sinutis and the calcification in the ethmoid and maxillary sinus. The previous reports shows extranasal aproch have been performed for sinuliths in the maxillary sinus8)9). Therefore, if the the calcification is indistinct under endoscopy, especially in frontal sinus, the extranasal surgery is seemed the one of
