초록
Post operative maxillary cyst may arise after the surgical treatment for maxillary sinusitis with the symtoms of swelling, pain, and pus discharge in the buccal region. It is examined by Waters' view, panoramic view and other intraoral radiographs, but quite variable radiologically. Most of the cyst is seen round or ovoid shape radiolucency, destruction, expansion and thinning of the lateral wall or posterior wall, and roots of the adjacent teeth may be resorbed. We studied about 117 cases of the post operative maxillary cysts which diagnosed in department of oral and maxillofacial radiology, Seoul National University Hospital. We analyzed and obtained following results. 1. These cysts occured more frequently in male than in female and the incidence is highest in the 4th and 5th decade. 2. Initial radical operation of maxillary sinus were performed mainly between the age of 10 and 45 years, and about 60% of the patients were 15 to 25 years. 3. Pain and swelling on buccal area, pus discharge, and toothache are most chief compaints, seven cases were found at routine examination without symtoms. 4. Most of these cysts were unilocular with smooth and well-defined border. 5. The majority of the cysts occurred in the anterolateral wall of maxillary sinus. 6. Dental changes of the lesional area were loss of lamina dura and root resorption, but about 55% were not changed.
