ABSTRACT

BACKGROUND: Beta- thalassemia major causes the basic skeletal changes due to ineffective erythropoiesis in suffering patients. The aim of the study was to determine the frequency of maxillo-facial anomalies and the hemoglobin and ferritin levels in patients with beta-thalassemia major compared to the healthy control group. METHODS: The present study was performed on 72 beta- thalassemia major patients and 70 healthy control group in Ahvaz, Southwest Iran, from Jan 2014 to Mar 2015. Panoramic radiographs were taken using a standard procedure. The frequency of abnormalities including enlargement of bone marrow spaces, small maxillary sinuses, thickness of inferior mandibular cortex, prominent antegonial notch, absence of inferior alveolar canal and thin lamina dura, were determined by two Oral and Maxillofacial Radiologist. We also paid to identification of the relationship between abnormalities frequency and hemoglobin and ferritin levels during previous 6 months in thalassemia patients. RESULTS: The mean age of case and control groups was 18.6±7.25 and 17 ± 6. 55 yr, respectively. The frequency of abnormalities in the case and control groups was as follows, enlargement of bone marrow spaces [69 (95.8%) vs 3 (4.3%)], small maxillary sinuses [45 (62.5%) vs 1(1.4%)], reduced thickness of inferior mandibular cortex [21(29.2%) vs 6 (8.6%)], prominent antegonial notch [10 (13.9%) vs 2 (2.9%)], absence of inferior alveolar canal [68(94.4%) vs 41(58.6%)] and thin lamina dura [40 (55.6%) vs 5 (7.1%)]. CONCLUSION: The all above mentioned abnormalities in patients with beta-thalassemia major was higher than the control group. Moreover, the frequency of maxillo-facial abnormalities decreased by increasing hemoglobin and decreasing ferritin.

ABSTRACT

Odontogenic myxoma (OM) is an infiltrative benign bone tumor that occurs almost exclusively in the facial skeleton. The radiographic characteristics of odontogenic myxoma may produce several patterns, making diagnosis difficult. Cone-beam computed tomography (CBCT) may prove extremely useful in clarifying the intraosseous extent of the tumor and its effects on surrounding structures. Here, we report a case of odontogenic myxoma of the mandible in a 27-year-old female. The patient exhibited a slight swelling in the left mandible. Surgical resection was performed. No recurrence was noted. In the CBCT sections, we observed perforation of the cortical plate and radiopaque line that extended from the periosteum, resembling "sunray" appearance-a rare feature of OM-which could not be assessed by panoramic radiography.
