Aim
To determine eustachian tube function in tubo-tympanic type of chronic ear disease and correlate it with pathological changes in middle ear.
Objective
To ascertain whether eustachian tube function had any demeanor upon the outcome of myringoplasty.
Backgound
The prevailing interest in the patho-physiology of the eustachian tube has been stimulated by the persistent incidence of middle ear effusion and chronic otitis media. The ongoing sophistication in current middle ear reconstructive surgery has added more dimensions to the study of eustachian tube and its effects in the course of reconstructive middle ear surgery. One of the prime elements accountable for failure of reconstructive middle ear surgery has been tubal dysfunction.
Method
In the present study eustachian tube function was evaluated in in 30 patients who were undergoing myringoplasty for tubo-tympanic type of chronic suppurative otitis media having central perforation by tuning fork tests, microscopic evaluation of the middle ear mucosa and Impedance audiometry.
Results
70% of the myringoplasty cases had good surgical outcome and of the 24 cases that had good eustation tube function 87.5% had successful surgical outcome remaining cases had recurrence of otorrhea.
Conclusion
The results were validating good eustachain tube function as a criterion for electing cases under middle ear reconstructive surgery and Impedance audiometer assures a superlative means of appraising Eustachain tube function. |
