[Morphologic classification of Reinke's edema through optical coherence tomography]. / Morphologische Klassifikation des Reinke-Odems mittels optischer Kohärenztomografie.

OBJECTIVE: Several classification systems for Reinke's edema have been proposed in the past, which are somewhat less than morphologically ideal. The objective of the present study is to evaluate the ability of optical coherence tomography (OCT) to attain a reproducible graduation of Reinke's edema. MATERIAL AND METHODS: In a prospective study, 30 consecutive patients underwent endolaryngeal, microsurgical resection of their Reinke's edema. Graduation was performed through OCT based on morphologic criteria, where each result was compared with that of other classification systems. RESULTS: In Reinke's edema grade I according to Glanz, a feathered pattern is found, while Reinke's edema grade II demonstrates a lacunar and Reinke's edema grade III a confluent pattern. Correlation between the different classification systems was uniformly weak and not significant. CONCLUSIONS: Due to the three different recognizable patterns, OCT qualifies as an objective and reproducible aid for the graduation of Reinke's edema and gives certain insights in its pathogenesis.
