Outcome of surgery for chronic suppurative otitis media with resistantPseudomonas aeruginosa

Objective To assess the effectiveness of surgical treatment of active chronic suppurative otitis media (CSOM) with ciprofloxacin-resistantPseudomonas aeruginosa(P. aeruginosa) that failed comprehensive local and systemic treatment. Study design Retrospective case review. Setting Tertiary referral center. Patients Eleven patients with ciprofloxacin-resistantP. aeruginosaCSOM that remained active despite comprehensive local and systemic treatment. All patients were operated by a single surgeon between February 2016 and July 2019 Intervention(s) Tympanoplasty alone was performed in seven cases and accompanied by mastoidectomy in the other four cases. Main outcome measure(s) Resolution of infection and tympanic graft take on otoscopy. The secondary outcome measure is hearing. Results Tympanic graft take was successful and the infectious process was resolved in 8 out of the 11 cases, yielding a success rate of 73%. The average follow-up was 20 months. No surgical complications occurred. Conclusions Tympanoplasty, with or without mastoidectomy, is safe and yields acceptable anatomical and functional success rates when intensive local and systemic treatment fails to stop the purulent discharge.

Automated summary

The study retrospectively evaluated the effectiveness of surgical treatment for ciprofloxacin-resistantP. aeruginosaCSOM, showing a high success rate in resolving infection and achieving tympanic graft take with tympanoplasty. No surgical complications occurred during the procedures, and the average follow-up period was 20 months.
