Summary : Objectives: This study aims at determining whether CT is superior to ultrasound in providing more accurate information in the investigation of submandibular gland tumours. Materials and Methods: A retrospective study was carried out between 2005 and 2010. Thirty-five (35) patients who presented with sub­mandibular gland swelling and had diagnostic ultrasound or CT/MRI prior to surgery and histological examination of tissues removed at surgery were investigated to determine the correlation between radiologic diagnosis and histologic diagno­sis. Results: CT was used in the pre-op assessment of 22 patients, 12 of which had correct diagnosis when compared with the histology findings while ultrasound was used in pre-op assessment of 13 patients, 12 of which concurred with the histo­logical diagnosis. With regards to ability to detect malignant lesion, ultrasound had much higher sensitivity than CT and comparable specificity. Therefore, in this study, ultrasound provided a better guide in the pre-op radiologic assessment of submandibular gland swelling. Conclusion: Our evaluation of pre-operative diagnosis of CT and ultrasound in the assessment of submandibular swellings reveal that ultrasound is better in determining the nature of the lesion.
