Abstract

Background
Chronic suppurative otitis media (CSOM) is a major cause of conductive hearing loss in developing countries. Myringoplasty is the standard treatment, but the influence of preoperative ear status (wet versus dry) on hearing outcomes remains unclear. This study compared postoperative hearing gain between wet and dry ear patients.

Methods
A pre–post comparative study was conducted in the Department of Otorhinolaryngology from February to July 2018. Sixty patients aged 20–50 years with tubotympanic CSOM and central tympanic membrane perforation were included. Participants were divided into two groups: dry ear (no discharge for ≥3 months) and wet ear (scanty discharge despite one week of antibiotics), with 30 patients in each group. All underwent myringoplasty and were evaluated using pure tone audiometry preoperatively and at 3 months postoperatively. Air conduction thresholds were calculated as the mean of 0.5, 1, and 2 kHz. Statistical analysis was performed using SPSS version 21, with significance set at p < 0.05.

Results
Among the 60 participants (48.3% males, 51.7% females), most were aged 20–30 years. Perforation size was comparable between groups. Both groups showed postoperative hearing improvement. The dry ear group demonstrated a mean gain of approximately 10–15 dB, with similar improvement observed in the wet ear group. Statistical analysis showed no significant difference between groups (t = 2.654, p = 0.058).

Conclusion
Postoperative hearing gain following myringoplasty did not differ significantly between wet and dry ear patients. Both groups showed clinically meaningful improvement, indicating that controlled ear discharge does not adversely affect surgical outcomes. Myringoplasty can be considered in selected wet ear cases after appropriate medical management.
