Outcome of surgery for chronic suppurative otitis media with resistant Pseudomonas aeruginosa.

OBJECTIVE

To assess the effectiveness of surgical treatment of active chronic suppurative otitis media (CSOM) with ciprofloxacin-resistant Pseudomonas aeruginosa (P. aeruginosa) that failed comprehensive local and systemic treatment.

STUDY

DESIGN

Retrospective case review.

SETTING

Tertiary referral center.

PATIENTS: Eleven patients with ciprofloxacin-resistant P. aeruginosa CSOM 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.
