Mean Time

Eustachian tube dysfunction is one of the well-known factors leading to development of chronic suppurative otitis media. Tube mucociliary transport is important for elimination of the inflammation products from the middle ear enabling recovery of the affected mucosa of the middle ear, local circulation and restoration of normal air pressure in the middle ear. The study was aimed at determining: 1. whether perforation site on the tympanic membrane influences tube mucociliary transport time in individuals with traumatic rupture of the eardrum; 2. possible time difference of tube mucociliary transport between group of patients with chronic suppurative otitis media and group of patients with traumatic rupture of the tympanic membrane; 3. possible time difference of tube mucociliary transport between chronic tubotympanic type of suppurative otitis media, so called tubotympanic otitis media and atticoantral type of chronic suppurative otitis media, the so called atticoantral otitis; 4. the association between the degree of defect of the tympanic membrane mucosa and time of tube mucociliary transport in each individual type of chronic suppurative inflammation of the middle ear. Eustachian tube mucociliary transport was studied in 16 patients with tubotympanic otitis, in 13 patients with atticoantral otitis and in 9 patients with traumatic rupture of the eardrum (control group of patients). All patients were treated at the Institute of Otorhinolaryngology and Maxillofacial Surgery, Clinical Centre of Serbia in Belgrade during 2002. Tube mucociliary transport was studied upon instillation of 10 ?l 5% sterile saccharine solution through the existing eardrum perforation in the course of preoperative preparation of the patient for surgical intervention. The time interval from the moment of sterile saccharine solution application till perception of the sweet taste in the mouth and pharynx was measured in studied patients. The obtained results were analyzed using the methods of descriptive and analytical statistics (t-test for small independent samples). The mean time of tube mucociliary transport in patients with traumatic rupture of the tympanic membrane was 7.6 minutes. The mean time of tube mucociliary transport in tubotympanic otitis with normal mucosa of the tympanic cavity promontorium was 15 minutes, while mean time of tube mucociliary transport in tubotympanic otitis with polypoid changes of the promontory mucosa was 24 minutes (t=5.218; p<0.01). Mean time of tube mucociliary transport in atticoantral otitis with normal promontory mucosa of the tympanic cavity was 35.5 minutes, while mean time of mucociliary tube transport in atticoantral otitis with polypoid changes of promontory mucosa was 48 minutes (t=6.99; p<0.01). In the irreversibly changed tympanic cavity mucosa, tube clearance saccharine test was negative even after one hour. The results of our study indicate the possibility that prolonged mucociliary tube transport has greater influence to development of atticoantral otitis rather than to development of tubotympanic otitis. The association between the degree of mucosal defect and time of mucociliary transport was evidenced in both types of chronic suppurative inflammation of the middle ear.

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.

Control Approach

Background: The AAA (Anterior epitympanic, Attic, and Antrum) space is the space between the mastoid and middle ear which functions to balance the pressure in both organs (buffer). Pathological tissue in the AAA cavity due to chronic infection would disrupt the buffer function and could change the morphology of the mucosa in the tympanic membrane and middle ear. Obstruction in the AAA space measured subjectively by observing the smoothness of the flow using saline solution has been shown to be associated with a plaque in the tympanic membrane (myringosclerosis) in Chronic Otitis Media (COM) patients. This study aims to determine the relationship between AAA space obstructions with myringosclerosis using CT-Scan for an objective result.Methods: Retrospective study with case-control approach used in this study. Case criterias are Chronic Suppurative Otitis Media (CSOM) patients with myringosclerosis, both men and women and age 15-50 years, while the control group are benign CSOM patients without myringosclerosis. Data were analyzed with the chi-square test to prove the association between the AAA space status and length of symptom onset with myringosclerosis.Results: During January 2017-December 2019 there were 33 respondents, 19 cases and 14 controls, 21 men and 12 women with an average age of 35 years (cases) and 23.5 years (control). The length of symptom onset more than 5 years (p <0.05, OR 6.94 with CI 0.5-1.5) and AAA space obstruction (p <0.05 OR 34.25 with CI 0.8-1.8) has been shown to be associated with myringosclerosis in people with benign CSOM.Conclusions: AAA space obstruction and symptom onset more than 5 years significantly associated with myringosclerosis.

Penicillin Treatment

Pseudomonas aeruginosa was injected intranasally into four groups of chinchillas to determine if these bacteria can invade the middle ear by way of the eustachian tube. One group completed penicillin treatment of bilateral penumococcal otitis media (POM), and the second group started penicillin treatment of bilateral POM at the time of P. aeruginosa injection. A third group had no POM, but completed a course of penicillin treatment before P. aeruginosa injection, and a fourth group had no POM and received no penicillin. Middle ear susceptibility to nasally injected P. aeruginosa was significantly higher in animals with POM (61%) than in animals without POM (32%, p = 0.001). Forced eustachian tube opening pressures did not correlate with P. aeruginosa susceptibility. Thus, P. aeruginosa, the principle pathogen of chronic suppurative otitis media, can invade the middle ear by way of the eustachian tube, and acute otitis media predisposes to middle ear infection by P. aeurginosa.

Tube Dysfunction

Otitis media is an in􀃸ammation of a part or whole of the mucoperiosteal lining of the middle ear cleft which is composed of Eustachian tube, h y p o t y m p a n u m , m e s o t y m p a n u m , epitympanum, aditus and mastoid air cells(1). It is one of the commonest ear disease of all age groups and it is caused by multiple interrelated factors including infections, eustachian tube dysfunction, nasal allergy and trauma. The disease has been classi􀃶ed on the basis of its underlying pathology as active or inactive mucosal, active or inactive squamosal and healed chronic otitis media (2). A number of factors are involved in the outcome of surgery for Chronic suppurative Otitis media and one of them is condition of the mastoid. According to Jackler and Schindler (3) Mastoid factors are extent of pneumatization and presence of in􀃸ammatory disease in mastoid. Holmquist and Bergstorm (4) in 1978 said that well aerated mastoid is a prerequisite for well ventilated middle ear and long lasting success.

Middle Ear Infection

The prevalence rate of chronic suppurative otitis media is high and its treatment continues to be a challenge for the otorhinolaryngologists. Due to middle ear infection, there may be pain, hearing loss and spontaneous rupture of the eardrum which results in perforation. Infections can cause a hole in the eardrum as a side effect of otitis media. The patients suffering from ear perforation or having a hole in eardrum require preventing entry of water in the ear. This article describes the development of ear cap using additive manufacturing and TRIZ (a collaborative tool) to prevent the entry of water in the ear during chronic otitis media.

Operative Findings

Background: Cholesteotoma is a benign but destructive lesion leading to ossicular necrosis. Objective: To see the frequency of incus bone erosion on mastoid exploration in chronic suppurative otitis media with middle ear cholesteotoma. Study Design: Cross-sectional descriptive study. Setting: This study was carried out in the Department of ENT Unit-2, Sir Ganga Ram Hospital, Lahore. Duration of Study: Fifteen months months (10th April, 2019 to 9th July, 2020) Sample technique: Non- probability purposive sampling Methods: One hundred and twenty patients were admitted through outpatient department of ENT Unit-2, Sir Ganga Ram Hospital Lahore. Patients were included after fulfilling the inclusion criteria and information was collected on a prescribed proforma. Finally during surgery under general anesthesia, the operative findings were noted to know the incus bone erosion after middle ear cholesteatoma formation in chronic suppurative otitis media. Results: A total number of one hundred and twenty patients of chronic suppurative otitis media with middle ear cholesteatoma were included. Out of which 80 (66.7%) were males and 40 (33.3%) were females(Table 1).The patients shown in table 2 were divided in six age groups (Table 2).Table 3 shows that the procedure of mastoidectomy was performed in 112 patients (93.3%) and modified radial mastoidectomy was performed in 8 patients (6.7%).Incus bone erosion in chronic suppurative otitis media with middle ear cholesteatoma in 102 patients (85%) and 18 patients (15%) have no incus bone erosion (Table 4). Conclusion: Ear discharge was the most common presenting characteristic of chronic suppurative otitis media with cholesteatoma. The majority of the cases had ossicular erosion, with the incus being the most common site of involvement. Males are more likely than females to develop cholesteatoma.
