Conductive Hearing Loss Treatment in Corpus Christi, TX

Conductive hearing loss occurs when the transmission of sound through the outer ear canal, eardrum, or the three small bones of the middle ear (the ossicles: malleus, incus, and stapes) is impaired. Unlike sensorineural hearing loss, which involves the inner ear or auditory nerve, conductive hearing loss is frequently amenable to medical or surgical treatment that can partially or fully restore hearing. At Corpus Christi ENT Sinus and Allergy, Dr. Todd M. Weiss specializes in the evaluation and treatment of conductive hearing loss at every stage of life.

Common Causes of Conductive Hearing Loss

Outer Ear Causes

  • Cerumen (earwax) impaction
  • Otitis externa (outer ear canal infection with edema)
  • Foreign bodies in the ear canal
  • Congenital atresia (absence or narrowing of the ear canal)

Middle Ear Causes

  • Otitis media with effusion (fluid in the middle ear)
  • Acute or chronic otitis media
  • Eardrum perforation
  • Otosclerosis (abnormal bony fixation of the stapes)
  • Ossicular chain disruption (from trauma, infection, or cholesteatoma)
  • Cholesteatoma (an abnormal, destructive skin cyst in the middle ear)
  • Eustachian tube dysfunction

Symptoms

  • Hearing that sounds muffled, as though you are hearing through cotton
  • Ability to hear better in noisy environments (the ‘cocktail party effect’ in reverse)
  • Difficulty hearing soft sounds
  • Better hearing in one ear than the other
  • A sensation of pressure, fullness, or blockage in the ear

Diagnosis

The evaluation of conductive hearing loss includes otoscopy, tuning fork tests (Weber and Rinne), pure-tone audiometry with air and bone conduction testing, and tympanometry. The audiogram will demonstrate an air-bone gap a difference between air and bone conduction thresholds confirming the presence of a conductive component. Imaging (CT scan of the temporal bones) may be ordered when ossicular pathology or cholesteatoma is suspected.

Treatment Options

Cerumen Removal

When earwax impaction is the cause, professional removal typically results in immediate restoration of normal hearing.

Medical Management of Middle Ear Infection or Effusion

Acute otitis media is treated with antibiotics. Persistent otitis media with effusion may be managed with observation, nasal corticosteroids, or antihistamines when allergy is a contributing factor.

Tympanostomy Tube Placement

For persistent middle ear fluid or recurrent infections, ear tube placement ventilates the middle ear and resolves associated conductive hearing loss.

Tympanoplasty

Closure of an eardrum perforation by tympanoplasty restores the acoustic properties of the eardrum and typically improves the associated conductive hearing loss.

Ossiculoplasty

When the ossicular chain is disrupted or eroded, surgical reconstruction using natural tissue or a prosthetic device (PORP or TORP) can re-establish the middle ear sound-conducting mechanism and improve hearing.

Stapedectomy for Otosclerosis

Otosclerosis abnormal bone growth that fixes the stapes to the oval window is treated surgically by stapedectomy or stapedotomy, in which the fixed stapes is replaced with a prosthetic piston. Success rates for hearing improvement are high, typically exceeding 85 to 90 percent.

Hearing Aids

When surgery is not feasible or desired, hearing aids including bone-anchored hearing devices (BAHA) for patients with chronic ear disease or congenital ear canal abnormalities are effective alternatives.
