The electronic probe provides a simple means to detect eustachian tube patency, and can be used as a sensitive probe of objective tinnitus. The basic unit consists of a battery-operated, electronic amplifier connected by 18-in leads to a sensitive microphone and to a small speaker (Fig 1). These transducers are each connected to rubber nipples of the type used for impedance audiometry (Fig 2).

Introduction Eustachian tube (ET) dysfunction plays an important role not only in the pathophysiology of various middle ear disorders, but also in predicting the outcome of the treatment. As there is no single test that assesses both the anatomic and physiological functions of the ET, a combination of tympanometry and dynamic slow motion video endoscopy may improve the sensitivity of ET function assessment. Objective To find out if there is any correlation between dynamic slow motion nasal video endoscopy and impedance audiometry in assessing ET function in patients with middle ear diseases. Methods Ours was a descriptive study performed with 106 patients attending the Ear, Nose and Throat (ENT) Outpatient Department of a tertiary care center in South India with features suggestive of middle ear disease. All patients underwent impedance audiometry and dynamic slow motion nasal video endoscopy, and were graded based on the severity of the ET pathology. Results A total of 47 out of 97 patients with abnormal endoscopy findings also had abnormal impedance audiometry. The correlation was greater among the patients with higher grades of ET dysfunction. The endoscopy findings of 106 cases, when correlated with middle ear manometry, revealed that 56 cases showed complete agreement, and 50 cases showed disagreement. The nasal endoscopy results, when correlated with middle ear manometry studies by using McNemar's chi-squared (χ2) test, showed a significant association between the 2 tests (p = 0.017). Conclusion There is a significant alteration in middle ear pressure as the severity of the ET tube dysfunction increases. Impedance audiometry and nasal endoscopy provide a better measure of ET function.

Perhaps the best way to clarify my position for Dr. Magian is to consider the benefit/cost ratio of impedance audiometry for routine screening of children. (As a research tool I support its use strongly.) Let us first consider the benefit of routine screening and how firmly established this benefit is. The major benefit claimed is that tympanometry identifies eustachian tube dysfunction with greater sensitivity than other techniques. To quantitate this benefit one needs to know the proportion of children identified by this, but not by other, techniques.

AbstractTinnitus is a symptom of many disorders affecting the auditory system. While Impedance Audiometry provides no specific etiologic information about tinnitus, it is a useful diagnostic tool to localize various types of auditory dys-function. This paper sketches usefulness of impedance testing in diagnosis of retro-cochlear lesions, in otosclerosis and in objective tinnitus.

ABSTRACT Introduction The correlation between middle ear pathology due to Eustachian tube dysfunction and nasal allergy has been a topic of debate since long. Studies of the pathogenesis of otitis media have identified interactions among infection, allergic reactions and Eustachian tube dysfunction. AIMS- The aim of this study was to evaluate the relationship between Eustachian tube dysfunction and nasal allergy and to evaluate the efficacy of oral steroids and intranasal steroidal spray on Eustachian tube dysfunction. Materials and methods The patients were diagnosed according to the diagnostic criteria of allergic rhinitis. A total of 50 patients having moderate/severe symptoms who had not taken any treatment for allergic rhinitis in the past 6 weeks with deranged middle ear function were included in the study. Group I patients were given Prednisolone, 30 mg once daily for 10 days in tapering dose along with intranasal steroid spray for 6 weeks. Group II patients were given only intranasal steroid spray for 6 weeks. Impedance audiometry was repeated at the end of 6 weeks and results were statistically analyzed. Result This study demonstrated the outcome of systemic steroids and intranasal steroidal spray in the treatment of middle ear dysfunction. In our study impedance audiometry was done at the start of study and showed type B tympanogram in 36% ears in group I and 21% in group II and type C tympanogram in 60% in group I and 50% in group II. Impedance audiometry was repeated at 10 days of treatment and showed reversal to type A curve in 26% of ears in group I and 14% of ears in group II. Impedance audiometry at the end of treatment demonstrated reversal to type A tympanogram in 64% of ears in group I and 48 % of ears in group II.

Patulous Eustachian Tube

Objectives: We sought to treat autophonia due to a patulous eustachian tube using botulinum toxin. Methods: Because we assumed that the patulous eustachian tube was caused by abnormal activity of paratubal muscles (tensor and levator veli palatini muscles and salpingopharyngeus muscle), paralysis was performed via injection of botulinum toxin type A in a 45-year-old female professional musician who had had chronic unilateral autophonia for 20 years. In addition to a patient interview, an endoscopic examination of the nasopharynx (posterior rhinoscopy), ear microscopy, and impedance audiometry were performed to verify the diagnosis and the outcome after treatment. Results: The autophonia disappeared 1 week after treatment. Normalized tympanic ventilation was verified by impedance audiometry after 8 weeks. The period of symptom relief was 9 months. Conclusions: The administration of botulinum toxin type A provides a new option in the treatment of patulous eustachian tube. The reliability of this method and the effect of repeated injections remains to be proved in future studies.
