In order to establish a simple stimulus-response characteristic of Eustachian tube physiology in children, the tubal ventilatory function was studied. The parameters of active and passive opening of the tube were measured for three groups of patients with non-intact tympanic membranes. The group with traumatic perforations of the tympanic membrane without any history of middle ear disease had better active equilibration function than the group with chronic otitis media and perforations of the tympanic membrane and the group with tympanostomy tubes in the tympanic membrane. Quantitatively, this could be expressed in terms of residual positive pressures. In the study of repeated inflation of the middle ear, all groups had lower second opening pressures which are attributed to the effect of surface forces.

Tympanoplasty and tympanostomy tubes were developed at the same time and have dramatically changed the treatment of chronic middle ear disease. One hundred forty-nine children who had tubes inserted between ages 6 months and 8 years for chronic otitis media with effusion have been prospectively followed up for an average of 4 years. Fourteen percent developed tympanic membrane perforations. No preoperative factor completely predicted the development of perforation. a majority of the perforations closed spontaneously. Three ears had noncontiguous observations of perforations during follow-up. The implications of these findings are discussed with respect to tympanoplasty.

Tube Function

<p class="abstract"><strong>Background:</strong> Auditory tube dysfunction is suspected as primary cause of chronic otitis media and leads to surgical related complications in otitis media with tympanic membrane perforation. The diagnosis of eustachian tube malfunction is essential to know the pathogenesis of chronic otitis media.</p><p class="abstract"><strong>Methods:</strong> A total 150 cases and 75 age, sex matched control subjects between age group 20-50 years were selected. Pre and post-surgical history was noted and detailed ear examination, tympanometry was done. Auditory tube function was evaluated through Valsalva test, nasopharyngoscopy, pneumatic otoscopy. Intact tympanic membrane was assessed by Williams test, perforated tympanic membrane by Toynbee’s test.  </p><p class="abstract"><strong>Results:</strong> Postoperative assessment of eustachian tube function by Toynbee’s test for 19 cases with failed tympanoplasty showed normal ET function in 5 cases, 8 cases had partial and 6 cases had gross ET dysfunction. Postoperative assessment ET function by William’s test showed 4 cases among 19 cases had partial ET dysfunction and 01 cases had gross ET dysfunction.</p><p class="abstract"><strong>Conclusions:</strong> Efficient surgical outcome of middle ear complications always depends on eustachian tube function. Most of the cases with residual CP showed partial or gross ET dysfunction. Patients with tubal dysfunction should be evaluated for underlying cause and treatable causes should addressed before proceeding for surgery as it increases the success rate of tympanoplasty.</p>

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.

Objective: The purpose of this study was to evaluate the etiopathogenesis of middle ear granulations in cases of Chronic Otitis Media (COM) and their management. Materials and Methods:Aprospective study was conducted on 100 patients over a period of 12 months. Patients clinically diagnosed as COM and operated, with the ndings of granulations in middle ear were included in this study. Each of these patients was subjected to complete history and thorough ENT examination after taking proper written informed consent. Clinical and laboratory data from the study was recorded as per the proforma. Results:Analysis of data revealed that maximum cases were found in the second or third decade of life with a male preponderance. Rural patients were 75% as compared to those from urban background 25%. Mucosal type of COM was found in 69% patients and squamous type in 31% patients. Maximum patients presented with history of discharge since 5-10 years, mostly mucopurulent type of discharge. Granulations were found to be present at more that one site in middle ear in most of the patients. Incus was the most commonly involved ossicle. Conservative management included chemical cautery and aural toilet followed with antibiotics with topical steroid.

<p class="abstract"><strong>Background:</strong> Chronic otitis media is one of the common infections seen in pediatric age group. The most widely recognized route of infection is via the eustachian tube. The inflammation of the pharyngeal end of the eustachian tube may prevent gas exchange, leading to lowering of the middle ear pressure and predisposes to aspiration of nasopharyngeal microbes into the middle ear cleft.</p><p class="abstract"><strong>Methods:</strong> Eighty (80) cases of clinically diagnosed chronic otitis media among pediatric age group of both sexes selected on simple random basis were included in this study. Swabs from both ears and throat were taken and the samples were sent under strict aseptic conditions for culture and sensitivity testing.  </p><p class="abstract"><strong>Results:</strong> The mean age of patients was 6.1years and the frequency of chronic otitis media was maximum in 1-5 years age group. Male to female ratio was 1.6:1.The most frequent organism isolated was <em>S. Aureus</em> followed by <em>Psuedomonas</em>. The ear swab and throat swab findings showed positive relationship (p&lt;0.05) for the common organisms i.e., <em>S. Aureus</em>, <em>pseudomonas</em> and <em>Streptococcus pyogenes</em> respectively, thus suggesting a common etiological agent. Psuedomonal infection was found to be associated with large perforation in tympanic membrane.</p><p class="abstract"><strong>Conclusions:</strong> The pathology in bilateral ear disease is central i.e., throat. Treatment in these cases is focused on selected drug with optimum dose and calculated regimen of treatment completely, thus reducing the morbidity of loss of physiological function of the ear and the grave complications involved.</p><p> </p>

Available Information

More than 2 million tympanostomy tubes are placed annually in the United States, primarily in children with chronic or recurrent otitis media refractory to nonsurgical management (J.S. Reilly, personal communication, 1994). Traditionally, the operating otolaryngologist has had the responsibility of caring for these patients, including: confirming middle ear disease, assuring tube patency, controlling refractory otorrhea, and managing complications such as tympanic membrane perforation or cholesteatoma. In response to pressures from a changing health care system, pediatricians are less able to refer children back to the otolaryngologist for routine tube surveillance, and must therefore perform it themselves, often with incomplete instrumentation and training. An approach is presented here for the care of the child with tympanostomy tubes based on the authors' combined experience with thousands of intubated children, and on available information from the pediatric and otolaryngic literature. With appropriate postoperative surveillance and follow-up care, the morbidity from tympanostomy tubes can be minimized. Although there are other ways of achieving the same goals, these time-honored methods are safe and effective. Because this is a visual guide, photographs are liberally interspersed to clarify and reinforce the written material. NORMAL TUBE APPEARANCE There are hundreds of different tube designs and materials and at least five different potential insertion sites in the tympanic membrane. This bewildering array of devices can be reduced to two general types: short-term tubes (intended to remain in the eardrum for 8 to 15 months) and long-term tubes (intended to remain in the eardrum &gt; 15 months) (Fig 1A and B).

Middle Ear Disease

The management of patients with middle ear disease should be based on an understanding of the pathogenesis of the disease and its course. In this group of investigations, patients with pathological conditions such as cleft palate, which affects ET function, are studied. Animal models are then developed to simulate the clinical condition, thus providing a method of isolating the variables.
