The Vanhuyse, Creten, and Van Camp (1975) model for analyzing high frequency tympanograms predicts the shapes of conductance, susceptance, and admittance tympanograms from the relationship between resistance and reactance tympanograms at the tympanic membrane. This model has been applied primarily to low impedance middle-ear pathologies but has not been applied extensively to the more commonly occurring high impedance pathologies. The purpose of this study was to extend the Vanhuyse et al. (1975) model to high impedance pathologies and to identify tympanometric parameters associated with otosclerosis, secretory otitis media, and lateral ossicular fixation. Data from previous experiments on the shape and absolute values of resistance and reactance tympanograms were used to calculate 678-Hz admittance tympanograms that were unique to each of the three high impedance pathologies. Guidelines for differentiating among the middle-ear pathologies on the basis of high frequency tympanometric shapes are presented.

Abstract Background Postural instability is a possible symptom in children with otitis media, which often occurs in this population. The child with balance disorders usually has intolerance to sudden movements, difficulties in moving in the dark, nausea, vomiting and numerous fall events. To verify whether changes in the middle ear can influence the balance postural in children from 3 to 5 years. Methods The sample consisted of 31 children of both sexes, aged between 3 and 5 years. To collect data, a tympanogram was used to analyze the integrity of the tympanic membrane and the Modifid Clinical Test of Sensory Integration and Balance (MCTSIB), with four different sensory conditions, to assess static postural balance. Results Regarding the tympanogram, it was verified that the majority of the sample showed no changes, 45.2% of which were type A and 32.3% of type C1. Regarding the type B and C2 tympanogram, it was found that 12.9% of the sample had type B tympanogram and 9.7% type C2. When comparing these values with the MCTSIB results, there were no significant differences between the tympanogram with changes (B and C2) and the tympanogram without changes (A and C1), regarding the child's balance performance. Conclusions In this study, it was concluded that the alterations of the middle ear, proved through the tympanogram, did not influence the postural balance. However, it was found that the unilateral changes reported by the tympanogram, suggest higher values of postural oscillation, compared to bilateral changes.

Introduction             Chronic otitis media (COM) is a most common and prevalent disease of the middle ear. COM has been defined as a longstanding inflammatory condition of middle ear and mastoid, associated with perforation of the tympanic membrane. Tympanoplasties are common surgeries performed for chronic otitis media in inactive mucosal type. Any otological surgery may involve a menace/ hazard of hearing loss post operatively.             In this study, an attempt was made to correlate, size of tympanic membrane perforation, pure tone audiometry and intra-operative findings in tympanoplasties, results were analysed and conclusion drawn. Materials and Methods Forty patients attending ENT OPD with chronic otitis media (COM), inactive mucosal type, with conductive hearing loss undergoing tympanoplasties who were willing to participate in the study were selected.  Ear was examined pre-operatively to assess the size of perforation and then, pure tone audiometry (PTA) was done to assess the type of hearing loss and its severity. During tympanoplasty, middle ear was inspected for ossicular status and any other pathology was noted. Later, the size of tympanic membrane perforation, pure tone audiometry and intra operative findings were correlated with each other and analysed. Result  In small and medium sized perforation, PTA and intraoperative findings correlated with each other. Whereas, in large and subtotal perforation, there was no correlation. Conclusion             In small and medium sized perforation, middle ear inspection may not be necessary. Whereas, in large and subtotal perforation it is necessary.

The objective was to review our experience with clinical course, diagnostic and therapeutic profile of children treated for acute mastoiditis, and to investigate for possible susceptibility factors. Study was designed as retrospective review of pediatric patients presenting with acute mastoiditis secondary to acute otitis media over the last 6 years, from 2000 to 2006. The study involved children aged from 1 to 16 years treated for acute mastoiditis and subsequent intratemporal and intracranial complications in Clinic for otorhinolaryngology, Clinic Center Banja Luka. Selected clinical parameters, mastoid coalescence and risk factors for necessity of surgical intervention were analyzed. Medical history review of a total of 13 patients with acute mastoiditis was analyzed. Acute coalescent mastoiditis occurred 11 patients (84%) while noncoalescent form of acute mastoiditis occurred in 2 cases (16%). Intracranial complication occurred in 3 patients (2 meningitis and 1 peridural intracranial abscess), while 2 patients had intratemporal complication (subperiostal abscess) associated to coalescent mastoiditis. We observed clinical profile of acute mastoiditis in regard to pathology found on the tympanic membrane, middle ear mucosa and destructions on the bony wall of the middle ear and mastoid. The main signs of progressive infection were tympanic membrane perforation, pulsatile suppurative secretion from the mucosa, and intratemporal abscess. All patients with coalescent mastoiditis required mastoidectomy, while noncoalescent mastoiditis was treated conservatively with broad-spectrum intravenous antibiotics and myringotomy. In conclusion acute mastoiditis is uncommon but serious complication of acute otitis media in children associated with significant morbidity. Coalescent mastoiditis concomitant with subperiostal abscess, intracranial complications and mastoiditis not responsive after 48 hours to intravenous antibiotics should urge clinician to timely mastoid surgery.

The author notes that diphtheria, especially primary diphtheria of the outer ear, is extremely rare. The usual way of spreading the infection should be considered the pharynx, the Eustachian tube, the middle ear, and finally the outer ear. Therefore, all cases of supposedly primary diphtheria with perforation of the tympanic membrane and former, existing or subsequent otitis media should be considered doubtful.

Thirty-five cholesteatomas medial to intact eardrums were treated in 34 children between 1976 and 1982. Six (18%) children had never had a documented episode of otitis media. Seventeen (50%) children, in whom the lesion was diagnosed at an early stage, underwent simple excision of the cholesteatoma without the need for extensive middle ear surgery. Findings from postoperative audiograms were normal for all such children. Cholesteatoma has recurred in eight (23%) children to date. Most recurrences were diagnosed 15 months or less after surgery. Routine careful otoscopic examination is essential in order to discover cholesteatoma at an early stage and to avoid hearing loss and the need for extensive otomastoid surgery. In order to perform an accurate examination of the eardrum, a halogen-illuminated otoscope and pneumo-otoscopy should be used by the pediatrician routinely. Particular attention should be paid to the posterior-superior quadrant of the tympanic membrance where a cholesteatoma is usually located.

The acoustic otoscope measures the amount of sound reflected from the tympanic membrane. Since the amount of reflected sound is increased by fluid in the middle ear, it seemed likely that the acoustic otoscope could be used for detection of otitis media. We compared acoustic reflectometry with over 4,000 tympanometric and otoscopic examinations in 451 children who were examined at regular intervals following surgery for chronic otitis media with effusion. The data indicate a lower sensitivity and specificity of acoustic reflectometry than had been reported previously. The receiver-operator characteristics of this device are discussed.

AbstractThe aim of the study was to review the literature of tympanoscierosis especially its pathogenesis, to study the general incidence of tympanoscierosis among patients with chronic suppurative otitis media (CSOM), its association with cholesteatoma and also the type of hearing loss as well as its relation to the degree and site of tympanosclerosis.Seven hundred and seventy-five patients with CSOM were studied retrospectively. A full history was taken and thorough ENT examinations were carried out. Pure tone audiograms (PTA) of all patients were done and analysed. The operative finding of tympanosclerosis as well as middle-ear status were inspected.The incidence of tympanosclerosis was found to be 11.6 per cent (90 patients out of 775 CSOM cases). Most tympanosclerosis cases had dry ear, (85.6 per cent). Of the 57.8 per cent who had myringosclerosis, their PTA showed an AB gap 20–40 dB. When sclerosis affect both the tympanic membrane and middle ear, 61 per cent of patients had an AB gap >40 dB. The association of cholesteatoma and tympanosclerosis may be regarded as uncommon, 2.2 per cent.The exact aetiology and pathogenesis of tympanosclerosis is as yet not well known. Our study concentrated on the clinical picture of tympanosclerosis among patients with CSOM. The majority of hearing loss associated with tympanosclerosis was of the conductive type.
