Area of Science:

  • Otolaryngology
  • Surgical Technology

Context:

  • Tympanoplasty involves reconstructing the eardrum and middle ear.
  • Traditional methods can cause significant trauma to the ossicular chain.
  • Bleeding can complicate surgical procedures and affect outcomes.

Purpose:

  • To evaluate the efficacy and safety of semiconductor diode laser use in tympanoplasty.
  • To explore the specific indications for diode laser application in this procedure.
  • To report initial clinical outcomes and benefits.

Summary:

  • The diode laser was utilized in 14 tympanoplasty surgeries.
  • Key applications included managing bony fixation of the malleus and incus, fibrous scar tissue, and malleus head resection.
  • Postoperative outcomes were favorable, with no vertigo or facial paralysis, an average hearing gain of 24 dB, and 50% of cases achieving an air-bone gap within 20 dB.

Impact:

  • Diode laser application minimizes trauma to the delicate ossicular chain during tympanoplasty.
  • It provides effective control of operative field bleeding.
  • This technique is particularly beneficial for addressing bony adhesions in the middle ear.
