We used CT to examine the bone destruction sites of the entire bone wall of the maxillary sinus in cases of malignant tumors of the maxilla and in maxillary sinusitis cases to investigate the differences between the destructive findings of the bone of both patient groups. The study subjects consisted of 13 patients with malignant tumors of the maxilla and 45 patients with maxillary sinusitis. Destruction of the bone wall was seen in 100% of the patients with malignant tumor of maxilla patients and in 57.8% with the maxillary sinusitis, hence showing a significantly higher incidence in malignant tumors of the maxilla. Neither group of patients exhibited disease-specific characteristics of their bone destruction. The incidence of posterolateral bone destruction in patients with malignant tumor of the maxilla patients was 61.5%, while it was significanty lower at 23.1% in the maxillary sinusitis patients. The number of bone walls affected was 2 or more walls in 84.5% of the malignant tumor patients of the maxilla patients and in 42.3% of the maxillary sinusitis patients. [ABSTRACT FROM AUTHOR] |
