The results showed that the DI was 1. 369, S % 16. 95, PI 26. 18 in malignant tumors; DI was 1. 171, S % 12. 41, PI 15. 54 in recurrent pleomorphic adenoma; DI was 1. 141, S % 12. 74, PI 13. 07 in pleornorphic adenoma, DI was 0. 999, S % 5. 10, PI 8. 00 in normal acini. Analysis of variance showed there was a significant difference (P<0. 01 ). The average DNA contents of shallow on deep lobe of contiguous tumors was 1. 08 in DI, 10. 65 in S %, 13. 49 in PI in malignant tumor, 1. 06 in DI, 8. 96 in S % and 9. 85 in PI in pleomorphic adenoma, which were all higher than in normal acini (P>0. 05). It was concluded that the levels of DI and S % of parotid tumor and its contiguous acini are related to degree of malignancy or recurrent condition of the tumors, suggesting contiguous acini of parotid tumors had the strong capacity of proliferation, which might play an important role in recurrent or malignant change of the parotid tumors.展开更多

The shape, boundary and internal echoes were related to the malignancy of the tumor. The diagnostic criteria of parotid tumors were proposed. The sonograms of 32 surgical specimens of parotid tumors were compared with histopathologic findings to investigate the pathologic bases of various sonograms. The boundary echoes were related to integrity of the capsule of the tumor. The internal echoes were related to internal structures of the tumor.展开更多

Design: A retrospective study of cases series. Setting: Salmaniya Medical Complex, Otorhinolaryngology Department, Kingdom of Bahrain. Methods: A retrospective study was carried out, between January 2009 and December 2018, for all patients diagnosed with parotid tumors at the Department of Otorhinolaryngology, Head and Neck Surgery at Salmaniya Medical Complex, Manama, Kingdom of Bahrain. Data collection was made from medical records, I-seha and laboratory information system (LIS). 87 patients underwent parotidectomy, of which 30 were excluded due to unsatisfactory diagnoses or missing data. The results of fine needle aspirations were analyzed and compared with the corresponding histopathologic diagnosis. Estimation of sensitivity, specificity, negative predictive value, positive predictive value and accuracy of FNA were calculated. Results: Among the 57 evaluated cases, four cases were further excluded from the final analysis due to unsatisfactory FNA results, therefore only 53 cases remained. The mean age of patients was 48.6 ± 17.2 years. A concordance with histopathology results was observed. 47 cases were diagnosed as benign and five cases were malignant, however, 1 case was diagnosed as malignant by FNA, but not in histopathology. The overall diagnostic accuracy was 98.1% and the prevalence of parotid malignancy was 9.4%. Sensitivity and specificity were 100% and 97.9%, respectively. Positive predictive value was 83.3% while negative predictive value was 100%. Conclusion: Fine needle aspiration is a highly sensitive and specific test in evaluating malignant parotid gland tumors. It is useful and accurate, especially when used hand by hand with the clinical assessment and radiological findings.展开更多

The aim of the present study was to describe the indications and results of parotidectomies in the ENT department of the Idrissa Pouye General Hospital in Dakar. Patients & Methods: We conducted a retrospective study between January 1, 2004 and December 31, 2012, including all patients who had been consulted for a parotid tumor with or without histological evidence collected in the otolaryngology and anatomy-pathology department of the Idrissa Pouye General Hospital in Dakar. Results: We collected 31 patient files. The mean age was 47.45 years, with extremes of 16 and 74 years. Females predominated, with a sex ratio of 0.82. Swelling of the parotid region was the main reason for consultation in 100% of cases. Parotidectomy was the most frequently performed procedure, accounting for 41.93%. Benign tumors accounted for 72% of cases, the majority being pleomorphic adenomas (50%). The outcome was favorable in 67.74% of cases. Conclusion: Management of parotid tumors at HOGIP would be improved by informing and educating patients to consult early, and by upgrading the technical platform.展开更多
