Diagnostic efficiency of endoscopy may be improved using videolaryngostroboscopy (VLS) and bioendoscopic tools such as Narrow Band Imaging (NBI) or Storz Professional Image Enhancement System (SPIES). Current histological classifications are not powerful enough to clearly predict the risk to carcinoma evolution and technical issues such as sampling error, variation in epithelial thickness and inflammation hamper pathological examination. Almost all dysplasia grading systems are effective in different ways. The 2017 World Health Organization (WHO) system should prove to be an improvement as it is slightly more reproducible and easier for the non-specialist pathologist to apply. To optimize treatment decisions, surgeons should know how their pathologist grades samples and preferably audit their transformation rates locally. Whether carcinoma in situ should be used as part of such classification remains contentious and pathologists should agree with their clinicians whether they find this additional grade useful in treatment decisions. Recently, different studies have defined the possible utility of different biomarkers in risk classification. The main treatment modality for LD is represented by transoral laser microsurgery. Radiotherapy may be indicated in specific circumstances such as multiple recurrence or wide-field lesions. Medical treatment currently does not have a significant role in the management of LD. Follow-up for patients treated with LD is a fundamental part of their care and investigations may be supported by the same techniques used during diagnosis (VLS and NBI\/SPIES).<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1007\/s00405-020-06406-9","type":"journal-article","created":{"date-parts":[[2020,10,14]],"date-time":"2020-10-14T12:03:53Z","timestamp":1602677033000},"page":"1723-1732","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":30,"title":["European Laryngological Society position paper on laryngeal dysplasia Part II: diagnosis, treatment, and follow-up"],"prefix":"10.1007","volume":"278","author":[{"given":"Hans Edmund","family":"Eckel","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ricard","family":"Simo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Miquel","family":"Quer","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Edward","family":"Odell","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vinidh","family":"Paleri","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jens Peter","family":"Klussmann","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marc","family":"Remacle","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7990-8510","authenticated-orcid":false,"given":"Elisabeth","family":"Sj\u00f6gren","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cesare","family":"Piazza","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2020,10,14]]},"reference":[{"issue":"1","key":"6406_CR1","doi-asserted-by":"publisher","first-page":"123","DOI":"10.1111\/coa.12678","volume":"42","author":"M van Balkum","year":"2017","unstructured":"van Balkum M, Buijs B, Donselaar EJ, Erkelens DC, Goulin Lippi Fernandes E, Wegner I, Grolman W, Janssen LM (2017) Systematic review of the diagnostic value of laryngeal stroboscopy in excluding early glottic carcinoma.
