Diagnosis of<unk>  ulcers normally involves an endoscopy examination, and a biopsy sample is taken so that the ulcer can be examined for cancerous cells. Physical characteristics<unk> s can be physically identified and diagnosed by observing the presence of proliferative tissue originating from the vocal process of the arytenoid cartilage. Identification is carried out by laryngoscopy, which produces an image of the lesion in the form of an abnormal growth (nodule or polyp) or ulceration. The vocal process is overwhelmingly the most common laryngeal site for these lesions, although they have also been observed on the medial and anterior portions of the vocal folds. In nodule or polyp form,<unk> s generally have a grey or dark red colouring and measure 2 to 15 mm in size.<unk> s can occur unilaterally or bilaterally, affecting one or both vocal folds. Differential diagnosis Various methods are used to diagnose<unk>  which aid in differentiating it from other vocal fold pathology. Laryngoscopy can allow visualization of the suspected<unk>  while also checking for signs of vocal abuse. Laryngoscopy, as well as an acoustic analysis of the voice, can help rule out vocal fold paresis as an underlying cause. Microscopic examination of the tissue can help determine that the lesion is benign rather than cancerous, as would be the case in<unk> . Other methods such as laryngeal electromyography and reflux testing can also be used to evaluate the function of the vocal folds and determine if laryngopharyngeal reflux is contributing to the pathology.
