“…family; the literature data [5, 9–12] indicate that these fungi are causal to otomycosis in 1–38% of cases, although Mugliston and O'Donoghue [13] and Nielsen [14] report even higher rates – as many as 41–58% of patients. Aspergillus spp., on the other hand, are in the opinion of most authors [6–8, 15–19] responsible for diseases of the ear in 51–98% of patients.…”

Local lesions observed in otitis, create favourable conditions for the growth of fungi and development of mycoses both in the external and middle ear, as well as in post-operative cavities, especially in cases of open-type surgery. The objective of this study was: (1) to determine the prevalence of mycotic infections in inflammatory conditions of the ear; (2) to evaluate the relationship between the presence of fungi and clinical symptoms of inflammation; and (3) to construct a model of therapeutic procedure. The study concerned 345 individuals, including 295 patients (381 ears) who presented with symptoms of otitis. The mycological examinations revealed presence of fungi in 30.4% cases (116 ears). Positive culture results were obtained predominantly in patients with post-operative suppuration (52.8%). Otomycosis was more often associated with fungi of the genus Candida (3/5) than with fungi of the genus Aspergillus (2/5). The analysis of symptoms in otomycoses showed that in bacteria-induced otitis, pruritus, discharge, post-operative defective hearing and headaches are most common; the analysis of signs showed that reddened epidermis and lining of the tympanic cavity are statistically more frequent. The therapeutic protocol adopted in otomycoses yields good results: 89%--complete cure.

“…P aeruginosa is the most common pathogen in chronic suppurative otitis media, both with and without cholesteatoma. 74–89 As far more mastoidectomies are performed for chronic suppurative otitis media than acute otitis media, P aeruginosa is likely to be among the most common pathogens to be present when a semicircular canal is violated. 38 In contrast to S pneumoniae , P aeruginosa is an opportunistic pathogen, causing disease only in the presence of some breakdown in normal defense systems or barriers.…”

Hearing Preservation With Labyrinthine Ablation in Otitis Media

Objectives: Iatrogenic fenestration of the inner ear in the presence of otitis media is commonly associated with permanent hearing loss. Hearing can generally be preserved when the vestibular labyrinth is ablated in a controlled manner in noninflamed ears. The purpose of this study was to examine the feasibility of hearing preservation with violation of the inner ear in the presence of middle ear inflammation. Study Design: Prospective and controlled animal model. Methods: Otitis media was induced bilaterally in pigmented guinea pigs with transtympanic injection of Streptococcus pneumoniae, nontypeable Haemophilus influenzae, or formalin-killed nontypeable H influenzae. Two to 4 days after injection, the horizontal canal of one ear was transected and sealed. Hearing was tested before and after labyrinthine ablation. Results: Otitis media was induced in all ears. Bacterial cultures were positive in 19 of 20 S pneumoniaeinjected ears, and in 10 of 16 nontypeable H influenzae-injected ears. One week after surgery, elevation of click thresholds (> 15 dB) was encountered in none of the fenestrated or unfenestrated S pneumoniaeinfected ears, in two of six unfenestrated and three of six fenestrated nontypeable H influenzae-infected ears, and in one of five killed-nontypeable H influenzae-injected ears both with and without fenestration. Conclusions: These data suggest that ablation of a semicircular canal in the presence of middle ear inflammation or infection does not necessarily lead to profound sensorineural hearing loss. Hearing loss associated with iatrogenic violation of the semicircular canals may be more dependent on factors other than the presence of nonspecific middle ear inflammation.

BACKGROUNDOtomycosis is a frequently diagnosed entity by an otolaryngologist with non-specific symptoms ranging from pruritus, aural fullness, and ear discharge and ear pain. Accurate diagnosis requires a high degree of suspicion, especially in cases of chronic suppurative otitis Media.The aims of this study were-1. To investigate the prevalence of otomycosis in patients with chronic suppurative otitis media 2. To identify fungal pathogens present in chronic suppurative otitis media. 3. To identify bacterial flora in the ear discharges. MATERIALS AND METHODSPresent study is a Descriptive study. Study population included 322 patients with chronic suppurative otitis media who attended the Department of ENT, Government Medical College, Thiruvananthapuram from February 2013 to January 2014. The discharge specimens were worked on for isolation and culture of bacterial, fungal organism. The results were analysed. RESULTSOtomycosis in chronic suppurative otitis media, mostly affected age group is 21-30, mainly females. House wives and manual labourers were more affected. Prior antibiotic ear drops (60%) and diabetes mellitus (22%) were the common predisposing factors. Cultures revealed Pseudomonas aeruginosa (56%) as the major bacterial pathogen and Aspergillus (75%) as the major fungal pathogen. CONCLUSIONSignificant numbers of cases of chronic suppurative otitis media with otorrhoea have super added fungal infections. It can cause refractoriness to usual topical antibiotic therapy and failure of surgeries. This study also shows that fungal culture is advisable in refractory cases before starting antibiotic therapy.
