[Roentgen diagnosis of mucosal cysts of the maxillary sinus].

The most common cystic lesion of the maxillary sinuses is the mucosal cyst. In reviewing a 5-years material of 5026 pathological X-ray examinations of the sinuses 12.2% of these were found to have mucosal cysts. These cysts usually do not give rise to symptoms and require no treatment, but are often erroneously diagnosed as polyps, compact maxillary sinuses, hypertrophy of the lining mucosa or tumors. As radiologic examination of the sinuses is a common procedure and the diagnosis of a mucosal cyst is possible other diagnoses may not be given in most cases.
