ABSTRACT
Abstract Introduction The role of elastin in tympanic retractions and chronic otitis media is not well established. Williams Syndrome (WS), a pathology related to a mutation in the elastin gene, could generate tympanic retractions. Objective To compare the prevalence of tympanic retractions among patients with WS and controls. Methods WS patients (n= 43 ears) and controls (n= 130 ears) were evaluated by digital otoscopic examination and the degree of tympanic membrane retraction was classified by 2 blinded experienced otolaryngologists. Results The agreement rate between the evaluators was 71.1% for pars tensa and 65% for pars flaccida retraction (p< 0.001). The pars tensa and pars flaccida retractions are present in patients with WS after an adjusted residue of respectively - 2.8 and - 2.6 (p= 0.011 and p= 0.022) compared with controls. Conclusions Tympanic membrane retractions are not more common in the WS group when compared with controls.
