Topical mitomycin-C (MMC) did not effectively prevent scar tissue formation in the postsurgical external auditory canal (EAC). Most patients required debridement, indicating limited success in preventing granulation tissue post-surgery.

Area of Science:

  • Otolaryngology
  • Surgical Innovation
  • Wound Healing

Background:

  • Scar tissue formation and granulation tissue in the postsurgical external auditory canal (EAC) can lead to complications.
  • Effective prevention strategies are crucial for successful surgical outcomes in EAC procedures.

Purpose of the Study:

  • To evaluate the efficacy of topical mitomycin-C (MMC) in preventing scar tissue and granulation tissue formation in the postsurgical EAC.

Main Methods:

  • A prospective pilot study was conducted involving six patients with recurrent postoperative granulation tissue.
  • Topical mitomycin-C (0.5 mg/mL) was applied to the EAC/mastoid cavity for 5 minutes.
  • Outcomes were assessed using a visual analog scale (VAS) for EAC occlusion and the need for debridement at 1 and 3 months post-application.

Main Results:

  • Fifty percent of patients showed improved VAS scores at 1 month, and 33% at 3 months.
  • However, 83% of patients required at least one debridement procedure for recurrent granulation tissue.
  • Two patients underwent repeat MMC application.

Conclusions:

  • Topical mitomycin-C was ineffective in preventing scar tissue formation in the postsurgical EAC.
  • Further research may be needed to explore alternative or adjunctive treatments for managing postsurgical EAC scarring.
