Abstract
The efficiency in the management of patients with suspected malignant lesions represents the main objective of the oncology of head and neck. Flexible nasopahyngolaryngoscopy with working channel allows to quickly and safely assess and obtain histological samples of this type of lesion. Our objective is to describe the usefulness of this technique in lesions suggestive of malignancy in terms of efficiency, sensitivity and specificity. A retrospective study was carried out over a period of time from December 2014 to December 2019, including patients biopsied with flexible fibroscopy of lesions of debut suspected of malignancy. Here we assess the location of the lesion, the histological results, the diagnostic time and the epidemiological variables. 104 patients were included in the study. More than half of the lesions, 55.2% (57), were located in the larynx; 57.7% (60) resulted positive for malignancy in the flexible fiberscope biopsy; 19.2% (20) were taken to the operating room to get biopsied under general anesthesia resulting in 7.4% (14) positive for malignancy, which shows a sensitivity of the test of 81%. In our sample, a diagnostic time of 15 days was obtained. Considering our results, the few complications and the revised literature, flexible fiberscope biopsy with working channel is an efficient procedure for the management of oncological patients of head and neck.
