Abstract:
The term chronic suppurative otitis media (CSOM) refers to middle ear infections lasting more than three months that lead to perforated tympanic membrane. Low socioeconomic strata of the society are more likely to have the disease in developing countries. There have been many studies focusing on the bacterial flora of CSOM, but little is known about the mycological aspects, which have become increasingly important over the last few decades. The present study was aimed to speculate the presence of fungal flora responsible for the cases of CSOM among patients who attended the Ear, Nose, and Throat Department of our hospital a tertiary care center. This retrospective study was conducted in a tertiary care centre after taking the approval of the protocol review committee and institutional ethics committee. Total 100 Patients of chronic otitis media were included with no history using ear drops for last one week and using two sterile swab without touching the external auditory canal, discharge was taken from middle ear and placed in sterile container and sent for potassium hydroxide (KOH) mount and observed. The age ranged from 18 months to 87 years and the mean age was 37.27+/- 12.59 years. The study population of male is 42 (41.6%) and female is 59 (58.4%). Distribution of KOH positivity observed for 33 (32.7%) and KOH negative for the study population of 68 (67.3%). When antibacterial treatment does not seem to relieve persistent otorrhea, otologists should suspect mycotic otitis media probable cause.
Insights
Fungal infections are a significant cause of chronic suppurative otitis media (CSOM), especially when bacterial treatments fail. This study investigated fungal presence in CSOM patients, revealing a notable rate of positive results.
Area of Science:
- Otolaryngology
- Mycology
- Infectious Diseases
Background:
- Chronic suppurative otitis media (CSOM) is a persistent middle ear infection often linked to socioeconomic factors.
- While bacterial causes are well-studied, the mycological aspects of CSOM are increasingly recognized as important.
- Limited research exists on the fungal flora contributing to CSOM.
Purpose of the Study:
- To investigate the prevalence of fungal flora in patients diagnosed with chronic suppurative otitis media.
- To identify potential fungal causes of CSOM in patients attending a tertiary care center's ENT department.
Main Methods:
- A retrospective study involving 100 CSOM patients was conducted.
- Middle ear discharge samples were collected using sterile swabs, avoiding external canal contamination.
- Samples were analyzed using potassium hydroxide (KOH) mounts to detect fungal elements.
Main Results:
- The study included 100 patients aged 18 months to 87 years (mean age 37.27).
- A significant proportion, 32.7% (33/100), of patients showed positive KOH mounts, indicating fungal presence.
- 67.3% (68/100) of the study population were KOH negative.
Conclusions:
- Fungal infections (mycotic otitis media) should be considered in cases of CSOM, particularly when standard antibacterial treatments are ineffective.
- The findings highlight the importance of mycological evaluation in managing persistent CSOM.
- Otologists should suspect fungal involvement in refractory otorrhea cases.
