Does Hearing Improve After Eardrum Repair Surgery?

When a tympanic membrane perforation occurs, whether from chronic otitis media or mechanical trauma, the consequence is far more complex than simple ear discharge or water sensitivity.

The healthy eardrum acts as a physiological acoustic transformer, intercepting sound waves from the air and concentrating vibrational energy across the tiny auditory ossicles (the malleus, incus, and stapes) toward the cochlear fluid.

A perforation disrupts this surface-area hydraulic ratio, resulting in an air-bone gap and conductive hearing impairment between 10 and 45 decibels depending on its size and position.

Furthermore, persistent exposure of the middle ear mucosa triggers chronic inflammation, potentially eroding the long process of the incus or fixing the stapedial footplate, compounding conductive deficits.

Accurate clinical assessment is comfortable, rapid, and non-invasive.

We initiate the evaluation using ultra-high-definition video-otoscopy to document the precise dimensions of the perforation, residual tympanic margins, and mucosal status.

Comprehensive audiometric evaluation follows, incorporating Pure Tone Audiometry and Speech Discrimination Testing to isolate the conductive component from potential underlying sensorineural loss.

High-resolution temporal bone computed tomography (HRCT) is employed whenever cholesteatoma, ossicular necrosis, or revision surgery is suspected, mapping ossicular chain integrity and middle ear aeration down to sub-millimeter detail before surgical intervention.

Modern tympanoplasty leverages high-magnification surgical microscopy or minimally invasive transcanal endoscopic ear surgery (TEES), eliminating large retroauricular incisions whenever possible.

Autologous grafting material, such as temporalis fascia or tragal perichondrium/cartilage, is sculpted to rebuild a robust, resistant membrane.

Crucially, middle ear exploration is conducted simultaneously: malleus, incus, and stapes mobility is palpated.

If ossicular discontinuity is encountered from long-standing disease, concurrent ossiculoplasty is performed utilizing titanium total or partial ossicular replacement prostheses (TORP/PORP) or autologous bone modeling to re-establish sound bridge conduction in one definitive operation.

The recovery period is vital for tissue vascularization and scaffold integration.

Patients are discharged on the day of surgery with absorbable gelatin sponges or sterile packing within the external canal, which temporarily produces a sensation of ear fullness or mild resonance.

Key precautions include keeping the ear rigorously dry, avoiding vigorous nose-blowing or closed-mouth sneezing, and refraining from air travel for 4 to 6 weeks.

As intra-canal packing dissolves, hearing begins to brighten within 4 to 8 weeks, with definitive auditory gains confirmed via follow-up audiometry at the 3-month milestone.
