Our Summary

This research paper analyzes studies from the past 10 years about mastoid obliteration, a type of ear surgery, in adults. The studies look at two types of grafts used in surgery: autologous (from the patient’s own body) and heterologous (from another source). The researchers looked at 37 different studies and analyzed the data statistically. The analysis didn’t show that one type of graft is better than the other, but it did highlight the benefits of each type.

The analysis included 2,882 cases of ear surgery. They found that the overall rate of otorrhea, a type of ear discharge, was 5%, with a slightly higher rate for heterologous grafts. The rate of recurrent and residual cholesteatoma, a type of skin growth that can occur in the ear, was 4.5%, with a slightly higher rate for autologous grafts. The rate of recurrent cholesteatoma was 1.8% and the rate of residual cholesteatoma was 1.5%, with similar rates for both types of grafts. The rate of tympanic membrane (the eardrum) retraction pockets was 5.3%, with a higher rate for autologous grafts. The rate of tympanic membrane perforations was 2.9%, with a higher rate for heterologous grafts. The infection rate was 2.3%, with similar rates for both types of grafts.

The analysis found that heterologous grafts were linked to significantly lower rates of recurrent and residual cholesteatoma and retraction pockets development. However, they were also linked to higher rates of otorrhea and tympanic membrane perforation.

Doctor’s Tip

A helpful tip a doctor might tell a patient about tympanoplasty is to carefully follow post-operative care instructions, including avoiding getting water in the ear, not blowing the nose forcefully, and refraining from activities that could put pressure on the ear. It is also important to attend follow-up appointments to monitor healing and address any concerns or complications that may arise.

Suitable For

Tympanoplasty is typically recommended for patients who have chronic ear infections, a perforated eardrum that does not heal on its own, or hearing loss due to damage to the middle ear bones. Patients with cholesteatoma, a condition where skin grows into the middle ear and can cause infections and hearing loss, may also be recommended for tympanoplasty. Additionally, patients with a history of ear trauma or previous unsuccessful ear surgeries may be candidates for tympanoplasty.

Timeline

Before tympanoplasty:

  1. Patient experiences symptoms such as hearing loss, ear pain, ear discharge, and recurrent ear infections.
  2. Patient undergoes a thorough examination by an ENT specialist to determine the extent of the damage to the eardrum and middle ear.
  3. Patient may undergo imaging tests such as CT scans or MRI to further assess the condition of the ear.
  4. ENT specialist recommends tympanoplasty as a surgical option to repair the eardrum and improve hearing.

After tympanoplasty:

  1. Patient undergoes the surgical procedure to repair the eardrum using either autologous or heterologous grafts.
  2. Patient is monitored closely post-surgery for any signs of infection, bleeding, or other complications.
  3. Patient may experience some discomfort and mild pain following the surgery, which can be managed with pain medications.
  4. Patient follows a strict post-operative care regimen, including keeping the ear dry and avoiding activities that could put pressure on the ear.
  5. Patient undergoes follow-up visits with the ENT specialist to monitor the healing process and assess hearing improvement.
  6. Over time, the patient’s symptoms such as hearing loss and recurrent infections improve, leading to a better quality of life.
