Correction to: European Archives of Oto-Rhino-Laryngology https://doi.org/10.1007/s00405-020-05851-w

In the original publication of the article, under the experimental protocol of the section “Clinical head position study in postoperative CRS patients”, the following sentence “There were 20 CRS patients, 12 male and 8 female across an age range of 19–64 years…” was published incorrectly.

The correct sentence should read as “There were 20 CRS patients, 12 males and 8 females across an age range of 19–66 years…”.
