Ultrasonographic Evaluation of Calcifying Cystic Odontogenic Tumor: A Case Report

The Calcifying Cystic Odontogenic Tumor(CCOT) is an uncommon lesion that demonstrates considerable histopathologic diversity and variable clinical behavior. A CCOT is rarely found in everyday practice. According to Kramer and Pindborg as well as majority of other authors’ classification, since 1992 the World Health Organization favored the use of the term calcifying cystic odontogenic tumor, described it as a cystic or neoplastic-like odontogenic pathological lesion of the jaw, and classified it as a benign odontogenic tumor. Ultrasonography(USG) is an inexpensive, non-invasive, and almost an available technique that is well tolerated by patient. In recent years many investigations focused on the use of ultrasonography in maxillofacial region as well as in intra osseous lesions of the jaws. This paper describes a 34 year old female with a painless mild swelling in the left anterior maxillary region associated with an impacted lateral incisor. The Panoramic, lateral occlusal and periapical view findings showed well-defined corticated unilocular mixed lesion with cluster of small pebbles calcifications. USG examination, using linear probe transducer, and also evaluation of location, size, internal echoe and boundary of the tumor were performed and documented. The main USG features of the tumor appeared as anechoic pattern cystic like lesion with some calcifying contents. Pathologic diagnosis was obtained by examining the surgical specimen. Therefore, ultrasonography may be used as an effective supplementary diagnostic tool for maxillofacial lesions

Clinical and Radiographic Evaluation of Styloid Process and Eagle Syndrome in Shiraz: Prevalence, Morphology and Symptoms

Introduction: Eagle syndrome, which can be a source of craniofacial pain, is caused by elongation of styloid process more than 25 mm. The present study aimed to assess the structural characteristics and prevalence of elongated styloid process (ESP), Eagle syndrome and the related symptoms in the adults aged above 20 years in Shiraz. Methods: In this cross- sectional study, 500 panoramic radiographs were evaluated in regard with styloid process length and morphology. In the presence of any symptoms in patients with ESP, they were clinically evaluated. Those symptoms reproduced by tonsillar fossa palpation were regarded relevant to ESP. Results: The prevalence of ESP was 35.2%, which  was proved not to be sex-dependent. Individuals aged 40-60 years and those with more than 60 years had respectively 1.76 (1.16-2.66, CR: 95%) and 2.01 (1.10-3.66, CR: 95%) times greater chance for ESP compared to those aged below 40. The most and the least prevalent structural morphologies were continuous calcification and multiple pseudo articulation respectively. Eagle syndrome was observed in 1.8% of the study population. Moreover, headache, dizziness, and foreign body sensation were respectively reported as the most evaluated symptoms. Conclusion: ESP was demonstrated to occur commonly in the study population which can get more prevalent by increasing age. With respect to avoiding unnecessary treatments, clinical examination of patients seem to be essential in order to differentiate Eagle syndrome from other sources with the same complications
