Intact Tympanic Membrane

AbstractWhitish pale looking mass in the middle ear space is a diagnostic challenge not only to a novice otologic surgeon but also for an experienced surgeon. The array of differentials should be known for appropriate site of origin and its true nature. We have discussed a case of pale looking tympanic paraganglioma behind an intact tympanic membrane with few differentials to consider.

Intact Tympanic Membrane

Primary ectopic meningioma of the middle ear is relatively rare in clinical practice. It is often difficult to distinguish it from chronic otitis media or otitis media with effusion due to its similar and atypical clinical symptoms. We report a case of epithelial tympanic ectopic meningioma with the main complaints of otalgia, aural fullness, and hearing loss. It was accidentally discovered during tympanotomy due to the symptoms of recurring refractory secretory otitis media. This article briefly reviews the relevant literature in recent years, summarizes the characteristics of primary ectopic tympanic meningioma with intact tympanic membrane, and emphasizes the diagnosis and treatment strategy of the middle ear mass.

AbstractBackground:Congenital cholesteatoma occurring behind the tympanic membrane is typically located in the anterior middle ear.Objective:To investigate the location, clinical features and treatment of cholesteatomas located behind an intact tympanic membrane in adults.Methods:Review of a series of 265 consecutive, new, adult cases of previously untreated cholesteatoma seen by the author over a 22-year period.Results:Seventeen (6 per cent) cases were located behind an intact tympanic membrane without any evidence of a retraction pocket of the attic or pars tensa. Ten (59 per cent) of these patients had undergone previous ear surgery and therefore the disease could reasonably be considered to be iatrogenic. The most common presentation was conductive deafness with no other symptoms (71 per cent). In all of the cases, the disease was located in the posterior half of the middle-ear space. The most common surgical management was simple excision of the disease via a tympanotomy. Two cases (12 per cent) developed residual disease.Conclusion:The majority of the cases in this series were likely to be acquired cholesteatomas. This type of disease often presents with conductive hearing loss alone.

<p class="abstract"><strong>Background:</strong> Determining the cause of conductive hearing loss with an intact tympanic membrane has been a challenge for the otologists for over decades<strong>. </strong>The aim of this study is to ascertain the usefulness of endoscopes to study the various middle ear pathologies on performing endoscopic exploratory tympanotomy.</p><p class="abstract"><strong>Methods:</strong> A retrospective analysis of various pathologies encountered in the middle ear in 88 patients who underwent endoscopic exploratory tympanotomy done over a study period of 3.5 years (January 2015 to June 2018).  </p><p class="abstract"><strong>Results:</strong> In our study, age of the patients ranged from 14 to 50 years with a mean age of 32 years.

Causes Of Failure

AbstractForty cases of failed combined approach tympanoplasty were analysed. The commonest cause of failure was adhesions between the facial ridge and the tympanic membrane, causing segmental attico-mastoid malaeration in 51.3 per cent of cases followed-up continually. Other causes were, large dermoids, incomplete removal of squamous epithelium, and eustachian tube obstruction. Eustachian tube dysfunction did not appear to be a major cause of failure.

Pressure Changes

Acute middle ear (ME) and inner ear changes following brief unilateral phasic ME pressure changes (up to ± 6000/mm H2O) were studied in the guinea pig. Middle ear findings included perforation of the tympanic membrane, serous and serosanguinous exudate and hemorrhage of tympanic membrane and periosteal vessels. Changes were related to magnitude of applied pressure. Perforation and hemorrhage were more commonly seen with negative rather than positive pressure. Air bubbles behind the round window were seen with positive pressures. Occasional distortion, but never perforation of the round window, was noted. Hemorrhage of the scala tympani was observed with both positive and negative pressures; scala vestibuli hemorrhage was found with negative ME pressure. In some instances pressure direction and magnitude related changes were seen in the contralateral ear.
