Letter to the editor

This is in reference to a very well written article titled 'Effects of surgical treatment of hypertrophic turbinates on the nasal obstruction and the quality of life' by Katharina Stölzel et al. [1].

However there are some concerns regarding the methodology which I would like to bring out.
