Endoscopic Management of Aural Myiasis: Experience of Two Decades

Cartine K

Background: The present study was undertaken to compare the efficacy of toendoscopic removal with conventional techniques in aural myiasis patients.

Methods: The 338, aural myiasis patients in study group were treated using Hopkine rigid toendoscope, the visible crawling caudal end of maggots was grasped with forceps & removed. Rests were identified from crawling movements or the visible caudal end buried in EAC and middle ear cavity and removed. Complete maggots clearance of ear cavity from EAC to middle ear cavity was done and same was repeated on other side if needed. Equal number of patients was treated using head light.

Results: The mean age in two groups was 55.5 years (range 02-68) in aural myiasis patients. There were 56.5% males and 43.5% females. Mean duration of aural symptom in both groups was 2 days. Endoscopically mean number of 42 maggots (range-10- 62) were removed in first sitting as compared to conventional technique where mean of 28 (range 10-48) maggots were removed (p<0.001). The mean duration of endoscopic treatment was 2days whereas in control group it was 6days. The difference was statistically significant (p<0.001).

Conclusion: Otoendoscopic procedure is superior to the conventional extraction method for removal of aural maggots. The larvae located in deep and inaccessible areas can be identified and removed easily. The disease was controlled in shorter time and ensures less damage to the middle ear structures.
