Anatomical anomalies of the Eustachian tube and chronic otitis media

I read with great interest the excellent article titled "Eustachian tube diameter: Is it associated with chronic otitis media development?" by Paltura et al. [1]. The authors measured the Eustachian tube (ET) diameter (ETd) on the diseased and healthy sides of the head in patients with unilateral chronic otitis media (COM) (a tympanic membrane perforation with or without purulent discharge), and found that anatomical anomalies of the ET were correlated with the incidence of COM. We recommend measuring the bony diameter of the ET during routine temporal computed tomography.
