The aim of this study was to assess the contribution of thallium-201 scintigraphy to primary tumour detection in patients with malignant neck masses and to evaluate its sensitivity and specificity. A total of 30 patients with histopathologically proven malignant tumours were included in the study. The sensitivity, specificity and accuracy of 201Tl scintigraphy were found to be 54%, 75% and 57% respectively. These results suggest that 201Tl scintigraphy has a limited value in the detection of the primary tumour in patients with malignant masses of the neck.
In this study, the cure and functional results of 133 functional neck dissections performed between 1992-1997 in Erciyes University Medical Faculty were evaluated. The overall recurrence rate was three per cent. This rate was 1.4 per cent for elective functional neck dissections and five per cent for curative functional neck dissections. Electromyographic studies showed that there was severe neurogenic deficit in the trapezius muscle of seven patients (12.5 per cent), and in the sternocleidomastoid muscle of 12 patients (21.4 per cent) among 56 randomly selected patients. In all cases, the flow rate and diameter of the internal jugular vein was found to be normal by Doppler ultrasonography. The results of this study showed that functional neck dissection is a reliable technique for obtaining a high cure rate and functional results.
The aim of this study was to assess the ability of 201Tl scintigraphy to differentiate between malignant and benign neck masses. Fifty-eight patients with neck masses, whose diagnoses were confirmed by histological examination, were examined. The sensitivity, specificity and accuracy of 201Tl scintigraphy were 80%, 96% and 88% respectively; when salivary gland masses were excluded, these values were 87%, 95% and 91% respectively. Our results suggest that 201Tl scintigraphy is highly reliable in determining the malignancy of neck masses, especially when salivary gland masses are excluded.
