Response to comment: Eustachian tube diameter: Is it associated with chronic otitis media development?

We would like to thank the observer for the interest and comments for our research. We also think that Chronic Otitis Media (COM) is a multifactorial disease and there were many factors involved in the pathogenesis. Upper airway infections, recurrent otitis media, dysfunction of the Eustachian Tube (ET) and nasopharynx, ciliary dysfunction, and allergy are among the investigated probable risk factors [1]. Also Chronic Rhinosinusitis (CRS) and Laryngopharyngeal Reflux (LPR) were proven to be involved in the pathogenesis [2,3].
