Introduction: Indirect laryngoscopy complemented by the laryngeal nasofibroscopy is the most frequent method evaluating neoplastic laryngeal pathology. We intended to determine the sensibility and specificity of these methods and understand their impact in the therapeutic strategy.
Material and Methods: We analysed retrospectively the clinical data of 314 patients performing diagnostic and therapeutic direct laryngoscopy under general anaesthesia between 2005 and 2010 in the ENT department of Hospital de São João. Clinical data from pre-operatory examinations (direct laryngoscopy and laryngeal nasofibroscopy) was compared to the histological study. Sensibility and specificity was calculated.
Conclusions: Indirect laryngoscopy and laryngeal nasofibroscopy are highly sensitive and specific detecting neoplastic and pre-neoplastic laryngeal pathology. The true value of these methods needs to be assessed by prospective studies.
