This prospective study evaluated the validity and reliability of tubomanometry (TMM) in 25 patients with sinus disease, 75 patients with middle ear disease and 25 healthy volunteers. After thorough clinical examination, the participants were evaluated with TMM, nasal endoscope, otoendoscope, Valsava manoeuvre, tympanometry, audiometry, ETDQ-7 (eustachian tube dysfunction questionnaire) and ETS-7 (Eustachian tube score). Tympanometry was used as gold standard for the study. The results of the study showed that Valsava manoeuvre had a high sensitivity of 86.3% while TMM, ETDQ-7, and ETS-7 had high specificity, with ETDQ-7 showing the highest specificity (87.4%). The authors use a combination of TMM and ETDQ-7 in their practice as they help to diagnose chronic obstructive eustachian tube dysfunction with a high degree of specificity and sensitivity.
