Restoration Surgery After Removal Of Advanced Cholesteatoma. What Can Be Done To Get Rid Of My Eustachian Tube Blockage?
Thank you for your query.
1. The reluctance for revision ear surgery is due to many factors such as chances of causing total hearing loss or a dead ear while manipulating a previously placed ossicular replacement prosthesis, facial paralysis, labyrinthine damage while clearing scar tissue and so on.
2. Cleft palate and lip is often accompanied by cholesteatoma formation.
3. It is difficult to correct Eustachian tube dysfunction by surgery. This is because the function of the inner (nasal) end of the tube depends upon many factors such as palatal muscle function among others. In the case of the Eustachian Tube, anatomical patency does not translate to physiological function.
4. The improvement in hearing that you experience after the Eustachian tube opens up is in the conductive component of your hearing loss. Does your Audiometry show a mixed hearing loss?
5. It is not clear from your description whether you have a post-op mastoid cavity in the left ear. If not, a Tympanometry (Impedance Audiogram) will reveal any Eustachian Tube Dysfunction.
6. If your Tympanogram shows Eustachian Tube dysfunction, a myringotomy with a titanium grommet may help improve your hearing in the short term.
7. Scarring at the inner end of the Eustachian Tube is difficult to tackle as the XXXXXXX carotid artery is very close to this end. Re-stenosis may be prevented by stenting with silastic. Balloon dilatation is a new option.
8. I recommend that you undergo an MRI for cholesteatoma with HRCT (High resolution CT) Temporal Bones, which is a new scanning protocol before any further surgical intervention. It is an excellent tool to rule out any residual or recurrent cholesteatoma and observe every minute change in the structure of the middle and inner ear due to surgery and the present position of the prosthesis. You may share the images here.
9. If you have not taken a trial with a BAHA device, I will suggest that you do so. A BAHA is an effective system to tackle you hearing loss and tinnitus.
10. Your Tinnitus may be due to a bulky prosthesis. Recent success in reducing tinnitus has been with Caroverine injections and transtympanic steroid injections.
I must emphasize that you have been under the care of a leading and world renowned ENT Surgeon. I am assuming that all medical treatment trial has been exhausted.
I will require access to your examination and clinical findings, detailed reports including previous operative notes, hearing test results, radiology images to give any further suggestions.
I hope I have answered some of your queries. If you have any follow up queries, I will be available to answer them.
Regards.
