Hi
@J.Angulo ,
Sorry to hear about this injury. From my own non-ENT perspective, a forceful Valsalva maneuver is definitely a precursor to inner ear barotrauma (IEBT). Anatomically, the three bones in the middle ear: malleus, incus, and stapes, aka the ossicular chain, are all connected end to end. The malleus lies against the tympanic membrane (eardrum), and the far ends of the stapes connect to a part of the vestibular apparatus (the inner ear) called the oval window. A forceful valsalva can cause the tympanic membrane to bow outward; the force is then transmitted to the oval window via the ossicular chain. The oval window can then rupture, producing a fistula (tear). The force can also be transmitted through the vestibular apparatus to the round window, which basically compensates for the motion of the oval window and keeps the pressure in the vestibular apparatus relatively stable. If that happens, the round window could rupture as well. Mild IEBT may not produce a rupture of the round or oval windows (aka perilymph fistula) but could still damage the delicate vestibular apparatus and result in inflammation.
What you're describing is consistent with a relatively mild case of IEBT - no hearing loss or vertigo, but you do have some lingering tinnitus and hyperacuisis (the noise sensitivity you mentioned). So, if you did suffer IEBT, it's likely either non-fistulating or the fistula was not clinically significant. The only way to definitively diagnose a fistulating IEBT is via surgery, and if your medical team thought that was indicated in your case, it probably would have already happened.
Ear injuries like this are notoriously slow to heal. Your ENT would be the best person to address specifics about recovery time, having evaluated you personally. If he/she lacks experience in this area, DM me your location in FL and I'll see if I can point you toward some resources.
I'll tag
@doctormike , our resident ENT, for his perspective as well.
Best regards,
DDM
