You would share your experience regarding Eustachian tuboplasty versus trans-tympanic ventilation tube insertion for treatment of Eustachian tube dysfunction.
I would say it is evidence based medicine, yet the quality of the evidence is poor.
No studies have been reported yet with a clear description of how ETD was defined. No control group was used and the outcome parameter has been defined poorly as well. Mostly the outcome parameter uses a form of tubomanometry (which in itself has no clear standardisation or validation). Therefore studies showing results are often biased in several ways
In regard to ventilation tube being the golden standard we are looking at almost the same quality of evidence regarding that treatment.
We need more estudies about procedure for treatment of Eustachian tube dysfunction. At the moment there,s no evidence and the gold standard is the ventilation tube. The future of middle ear chronic disease will change if we improve the management of ETD.
You are exactly right Dr. Er Van, we have to differentiate between primary ETD (of ET origin) & secondary ETD (of external origin e.g. nasal sinus or nasopharyngeal disease & may be systematic diseases). Then, we can direct Eustachian tuboplasty to primary ETD only so as to build up an accurate evidence based.
