LXXIII Early Detection of Middle Ear Malignancy

Background and Aim: A rare fungal infection, mucormycosis, has become more common in patients recovering from COVID in its second wave in India. The proximity and easy access to the middle ear through the Eustachian tube from paranasal sinuses alarms the need for early detection of middle ear involvement. Hence, the study was carried out to determine the influence of mucormycosis on Immittance and otoacoustic emissions. Methods: eleven rhino orbital mucormycosis patients aged 40-60 years participated in the study. Middle ear evaluation was carried out with the help of Immittance and otoacoustic emissions. Results: It was found that 4/11 (36.36%) participants had abnormal Immittance and absent otoacoustic emissions, indicating middle ear dysfunction. 3/4 participants had middle ear dysfunction in the ear ipsilateral to the side of the infection. Conclusion: The study results reveal a rare chance of middle ear involvement in mucormycosis patients, which calls for the crucial role of the audiologist in the early detection of middle ear dysfunction.

Early detection of middle ear effusions is highly desirable not only from a medical standpoint, but also educationally, psychologically and socially. Present methods do not appear to be adequate and the proposal has been made that impedance measurement may be of greater effectiveness in detecting abnormalities of middle ear function. Eighty children have been studied over a period of six to seven years during which time the middle ear function has been monitored by means of an impedance meter. Approximately one-half of the children have not indicated any variation in middle ear function over the period of observation. About one-third of the children have had isolated episodes of effusion from which they have recovered spontaneously and without adverse effects. The remaining one-sixth have had repeated episodes of effusion or persistent middle ear malfunction for substantial periods of time. Observation of the middle ear muscle reflexes at suitably chosen time intervals appears to have promise as a method of early detection of effusion in the middle ear.

High Risk Children

Otitis media (OM) is a very common childhood illness, with identified risk factors for chronicity and recurrence. Although a few treatment studies have described clinical factors that predict increased morbidity, there is little information on risk factors for middle ear sequelae of OM. These conditions have an estimated annual incidence of 0.5% to 4% among children with chronic OM with effusion. Prospective studies to identify risk factors for sequelae, although usually preferred by researchers, are expensive to conduct and impractical for rare conditions such as cholesteatoma. Knowledge of risk factors for chronicity and sequelae can be used clinically to target high-risk children for earlier, more aggressive therapy or more frequent surveillance and testing to prevent sequelae and increase early detection of these conditions. A clinician's advice about modifiable risk factors may motivate parents to decrease their child's exposure to factors that increase the risk of OM, OM chronicity, and sequelae. Research is needed to identify risk factors for OM sequelae by means of well-designed controlled studies.

Increased Sensitivity

Five subjects with normal middle ear mechanisms, and otosclerotic patients, before and after stapedectomy, matched the loudness of their voices to the loudness of a 125-cps-sawtooth noise. The results showed loudness matching functions with gradual slopes, less than 1.00, for the normal subjects and the patients prior to stapedectomy. Post-surgically, the loudness function for the patients increased in steepness to considerably more than 1.00. These results are explained, most logically, in terms of increased sensitivity of the altered middle ear to sound energy generated by the listener’s own voice.
