Nonvibrating segment predicting glottis carcinoma

Abstract

Endovideolaryngostroboscopy is the obliged evaluation tool in our everyday practice. Standardized protocol in management of broad spectrum of vocal pathology is useful in clinical, scientific and educational evaluation of patient from the first interview till the end of the treatment. Using of contemporary computerised multidimensional analysis of stroboscopic image we are approaching to optimum evaluation of any kind of interpersonal communication disorder. There were 66 patients in prospective clinical study of correlation between suspect endovideolaryngostroboscopic findings and histo-pathology verification of glottis carcinoma. Asymmetric and irregular vibrations with absent mucosal wave or absent vibrations of one part or of the whole vocal fold was improved as carcinoma in 85% of patients. The most frequent diagnosis was Ca planocellularae invasivum G2 NG 2, with subsequent open chordectomy. In every case of hoarseness longer more than 14 days, endovideolaryngostroboscopy is the golden standard for evaluating the need for microlaryngoscopy and biopsy.

Systematic review of the diagnostic value of laryngeal stroboscopy in excluding early glottic carcinoma

“…No other articles were excluded based on language. Eventually, 10 studies were eligible for critical appraisal. Cross‐reference checking of these studies on PubMed and Scopus did not reveal any relevant studies.…”

“…All 10 studies scored high on relevance (see Table ). The risk of bias was moderate in eight studies and high in two studies . Neither of the 10 studies clearly stated whether blinding of patients or the outcome assessor had been performed for the index test (laryngeal stroboscopy) or the reference test (histological evaluation).…”

“…This article was excluded from further analysis for these reasons. In the study by Vukasinovic et al ., standardisation of outcome was poor, because some patients had multiple biopsies to confirm a negative diagnosis whilst others did not. Furthermore, selection bias was suspected because the inclusion criteria were unclear.…”

Videolaryngostroboscopy in early vocal fold carcinoma diagnosis

“…The recognition of clinical manifestations and exposure to risk factors for the vocal fold carcinoma is important to primary care in order to promptly refer the patient to otorhinolaryngological examination and to establish a timely indication for microlaryngoscopy with biopsy [18][19][20][21]. VLS is very important prompt indicator for microlaryngoscopy with biopsy as a gold standard procedure for diagnosis of vocal fold carcinoma.…”

T1 Glottic Carcinoma

“…We observed relatively infrequent use of laryngovideostroboscopy in the evaluation of these patients, despite literature suggesting that it may be a useful technology in this setting. [21][22][23] This may be because the equipment is expensive and may not be readily available in many practices. We did note that use of laryngovideostroboscopy in the workup was associated with a treatment type that included local surgery and higher income and was more common for persons more recently diagnosed.…”
