I have a profesor in the Conservatory of music in Barcelona (Spain) and a student has an auditive problem which she is trying to solve. I send a description of her sympthomatology and diagnostic. I would appreciate very much any suggestions if someone could help her. allanas(at) ()+()+()+()+()+()+()+()+()+()+()+() The following paper is an explanation of a problem that I have on my left ear. I am a lyrical singer and this problem disturbs my auditive perception. Since what happens to me is not a big disturbance for non-musicians, doctors in Spain don't seem to have experience (I have gone to the best doctors during a year). I would appreciate very much any suggestions or information to be able to solve it (either by an auditive apparatus, surgery, etc.).

I hear an extremely loud inner resonance, an amplification of the sound which is very uncomfortable. I hear very differently from one ear to the other when I sing in the high register. 2. No tolerance to loud musical sounds from the exterior, especially when somebody else sings in a small room. 3. I don't feel comfortable either when I play the piano. The sound annoys m= e. 4. No tolerance to pressure changes: I notice altitude differences. I feel uncomfortable when I travel by train through tunnels and in the subway. I feel a lot of pain when I travel by plane, especially when it starts landing. I can also notice the pressure change when a door is closed in a small room (or a car) and I am inside. Diagnostic: The tympanum membrane of my left ear is too loose. Its convexity is too big. The membrane is too thin. Otoscopy: ^P bulging out (convexity) of the posterior quadrants without occupation of the box (0.7). (Left ear). Impedance test of 27.12.95. Left ear: (See paper enclosed) ear canal ml. 1.4 tymp peak ml. 6.0; pressure daPa +40 =46req Ipsi Contra Hz dB Hl 500 75 80 1000 95 90 2000 85 110 4000 85 100 Right ear: normal. Other results of impedance tests (different dates) are also enclosed. Results of other tests: Audiometry: normal. Both ears perfect, no difference. TAC: normal. Magnetic Resonance: normal. Evocate potentials: normal. Allergies: weak positive reaction to acari. =46ibroscopy: fine No damage in inner ear. My hearing is good. The only thing that is not normal is the tympanum. Treatments without positive results: 1. Anti-histaminics during three months. 2. A Cortisone injection: Celestone cronodose, 1 vial. 3. Vitamin B during two months. 4. Forced opening of the Eustachian tube with Politzer-ball and exercises to allow air to pass through the ears. Doctors say: (Dr. E. Perell=F3 and Dr. J. Marco) 1. The bulging out of the tympanum produces distortion and pain in the perception of sound. 2. The problem might be also due to an irregularity of the Eustachian tube. 3. The bulging out of the tympanum might be due to a previous infection (if it is so I didn't realize). Possible solutions: 1. Paracentesis: Making a small incision in the membrane to force it to close up tighter and stronger. 2. Drainage: Making a small incision in the membrane and inserting a tiny tube to equilibrate pressure changes. In this case, it would not be to drain anything. 3. Injecting "teflon" directly to the Eustachian tube to make it narrow. 4. Building up a new membrane (or reinforcing the membrane) by means of an injert from the outside ear tissue. I have been told that these three possibilities don't assure me an improveme= nt. With this problem I cannot sing. It seems it gets worse. I am ready to do anything that could improve it. I would like to know if there are better solutions or if I could wear some kind of auditive apparatus that could filter high frequencies to be able to sing comfortably.
