OBJECTIVE: To compare hearing results of single stage ossiculoplasty with second stage ossiculoplasty, and to provide a proper indication of operation options (single stage or second stage ossiculoplasty) according to patients' clinical conditions. STUDY DESIGN: Retrospective case review study. SETTING: Tertiary referral center. PATIENTS: A total of 175 patients with chronic otitis media. INTERVENTIONS: Tympanoplasty or mastoidectomy with tympanoplasty (M&T) as well as ossiculoplasty of either single or second stage between January 2009 and March 2016 by one surgeon (S.N.P.). MAIN OUTCOME MEASURES: Hearing outcomes evaluated by mean postoperative air-bone gap (ABG) and success rates in various subgroups of middle ear surgeries and different types of ossiculoplasty were analyzed. RESULTS: Among 175 patients, 120 underwent single stage ossiculoplasty, and 55 underwent second stage ossiculoplasty. The benefit of second stage ossiculoplasty in hearing results both at 3 months visit (p < 0.001) and 2 years visit (p = 0.003) were observed. The superiority of second stage ossiculoplasty was found in 20 dBHL cut off value with a statistical significance. The subgroups of canal wall down mastoidectomy and the first, non-revision middle ear surgery showed statistically significant benefits with second stage ossiculoplasty. CONCLUSION: Second stage ossiculoplasty has overall advantage in hearing results compared with single stage ossiculoplasty and could be more advantageous to the patient who needs canal wall down mastoidectomy or whose operation is the first middle ear surgery.
