From the Research

Unilateral tympanoplasty and ossiculoplasty may be appropriate for a patient with bilateral sclerotic mastoids and minimal soft tissue densities in the left Prussak's space, but careful evaluation is necessary before proceeding. The decision should be based on several factors including the patient's hearing status, symptoms, and extent of disease. The presence of sclerotic mastoids indicates chronic inflammation or previous infection, while soft tissue densities in Prussak's space suggest possible cholesteatoma or retraction pocket formation.

Key Considerations

  • Before surgery, a complete audiological evaluation should be performed to assess hearing loss and determine if the affected ear is the primary contributor to the patient's symptoms 1.
  • CT imaging should be reviewed to evaluate the extent of disease and ossicular chain status.
  • The surgical approach would typically involve a postauricular or endaural incision, tympanic membrane repair, and ossicular chain reconstruction using either autologous or prosthetic materials.
  • Postoperatively, patients require antibiotic ear drops for 7-10 days, avoidance of water exposure for 4-6 weeks, and follow-up audiometry at 6-8 weeks.
  • The contralateral ear should be monitored regularly as bilateral disease may eventually require intervention on both sides.

Evidence-Based Recommendations

  • A study published in 2021 found that tympanoplasty and ossiculoplasty should be considered to treat atelectatic middle ear and ossicular chain interruption, and that mastoidectomy does not add a favorable prognostic factor to the management of retraction pockets 2.
  • Another study published in 2018 found that second stage ossiculoplasty has an overall advantage in hearing results compared with single stage ossiculoplasty, and could be more advantageous to the patient who needs canal wall down mastoidectomy or whose operation is the first middle ear surgery 1.

Surgical Approach

  • The choice of surgical approach, either postauricular or endaural, depends on the extent of disease and the surgeon's preference.
  • Ossicular chain reconstruction can be performed using either autologous or prosthetic materials, with the choice depending on the extent of ossicular damage and the surgeon's experience.

Postoperative Care

  • Postoperative care is crucial to prevent complications and ensure optimal outcomes.
  • Patients should be instructed to avoid water exposure, use antibiotic ear drops, and attend follow-up appointments for audiometry and wound check.
