Abstract
Aim:To evaluate the accuracy of Ultrasonography as a diagnostic aid in cysts, benign tumors and malignancies of maxillofacial region.Objectives:This study was conducted to evaluate the accuracy of ultrasonography in the diagnosis of the osseous lesions of the jaws including cysts, benign tumors and malignant tumors. All the findings obtained by ultrasonography were compared and correlated with the clinical diagnosis, radiographic diagnosis and histopathological findings.Materials and Methods:The study was conducted on 42 patients with osseous maxillofacial swellings. The clinical and radiographic examination was carried out for all the patients who were afterward subjected to ultrasonography with color Doppler followed by histopathology. All the findings obtained were then statistically analyzed.Results:The utility of ultrasonography was evaluated considering histopathology as a gold standard. The diagnostic accuracy of ultrasound was found to be 100% in cystic lesions, 80% in benign tumors, and 85.71% in malignant tumors.Conclusion:Ultrasonography provides an accurate imaging of the head and neck region and does provide information about the nature of the lesion, its extent, and relationship with the surrounding structures. We propose the use of ultrasonography as an adjunctive examination for osseous lesions of the jaws before any invasive treatment.
Highlights
Maxillofacial tumors are commonly encountered in dental clinics
Ultrasonography provides an accurate imaging of the head and neck region and does provide information about the nature of the lesion, its extent, and relationship with the surrounding structures
The results of the present study allow concluding that ultrasonography can be a good and economical alternative for the diagnosis of maxillofacial swellings including osseous swellings such as cysts, benign and malignant tumors
Summary
Maxillofacial tumors are commonly encountered in dental clinics. History, the location of the lesion and radiographic findings can be helpful in the diagnosis; but due to the wide variation of the jaw lesions, sometimes the diagnosis becomes complex [1, 2]. Modern imaging techniques like digital radiography, Computed. Ultrasonography as a Diagnostic Aid in Evaluating Cystic Lesions. Tomography (CT), Magnetic Resonance Imaging (MRI) and nuclear medicine made an immense contribution in the diagnosis of intra-osseous and extra-osseous swellings in the head and neck region [2]. Ultrasonography is recognized as a safe, noninvasive and inexpensive method that has been found to be a reliable and sensitive diagnostic tool in head and neck for the evaluation of soft tissue masses, vascular neoplasms, deep neck abscesses, salivary gland diseases, cancer and nodal metastases [3, 4]. Recent studies have focused on potential applications of ultrasonography for diagnosis of temporo-mandibular joint pathology [3], fractures of facial bones and evaluation of the periapical lesions [5]
