EFFECT OF EUSTACHIAN TUBE OBSTRUCTION IN GRAFT UPTAKE RATE IN MYRINGOPLASTY

Abstract

Objectives: 
To observe the effect of eustachian tube obstruction in graft uptake/rejection rate in myringoplasty.
Materials and methods:
This study was done in Nepalgunj Medical College Teaching Hospital, Kohalpur, Nepal over the period of one year including patients with COM mucosal inactive with age more than 10 years. Standard underlay myringoplasty technique with temporalis fascia graft was used.
Results: 
There were total 60 cases, divided in two groups, 30 cases in each. Group 1 consists of patent eustachian tube and Group 2 consists of patients with eustachian tube dysfunction. Graft uptake was seen in 49 patients (81.7%) and rejected in 11 patients (18.33%). Out of 11 rejected cases 5 were from ET patent (GROUP 1) and 6 from ET obstructed (Group 2). Among 49 graft uptake cases, 25 (51.03%) were from Group 1 and 24 (48.97%) were from Group 2. In Group 1 graft uptake was 83% and was rejected in 17%, whereas in Group2 graft uptake was seen in 80% and rejected in 20% which was not statistically significant (p value 0.739).
Conclusions: 
There was no significant difference between two groups regarding the graft uptake.
