Severe Destruction

Chronic suppurative otitis media is defined as a chronic inflammation of the mucoperiosteal lining of the middle ear cleft. It is described as a persistent disease that is insidious in onset, often capable of causing severe destruction with irreversible sequelae, and clinically present with hearing loss and discharge. It has been classified into tubotympanic (safe) and atticoantral (unsafe) perforation. Cholesteatoma always occur in the atticoantral type and in marginal perforation. We report a case of cholesteatoma that occurred as a tubotympanic type of perforation.

<p class="abstract"><strong>Background:</strong> Chronic suppurative otitis media (CSOM) is a common condition seen in patients attending ENT department. The diagnosis of cholesteatoma is usually made on otologic examination. The necessity for HRCT imaging in an uncomplicated case is controversial. The objective was<strong> </strong>to evaluate preoperative HRCT temporal bone and to determine its’ usefulness in patients with Chronic suppurative otitis media (CSOM) undergoing surgery.</p><p class="abstract"><strong>Methods:</strong> This study was a prospective study involving 30 cases of CSOM with cholestaetoma. All the patients underwent pre-operative HRCT screening followed by surgical exploration of middle ear cleft. Pre-operative CT scan and intra-operative findings recorded and compared.  </p><p class="abstract"><strong>Results:</strong> Out of total 30 patients of CSOM, 16 (53%) were males and (90%) presented with chief complaints of otorrhoea. HRCT scan was found to be very sensitive (100%) in detecting cholesteatoma in middle ear cleft but differentiation between granulations or cholesteatoma wasn’t possible. HRCT satisfactorily delineated ossicular erosion except stapes suprastructure erosion which had 81.8% sensitivity and specificity 88.88%. For bony boundaries of middle ear, HRCT showed very high sensitivity and specificity for detecting scutum erosion, tegmen erosion, mastoid cortex erosion, jugular bulb dehiscence and bony external auditory canal erosion. It was moderately sensitive for LSCC Erosion (75%), Facial canal erosion (80%) and Sinus plate erosion (85.7%).</p><p class="abstract"><strong>Conclusions:</strong> These results indicate that preoperative CT temporal bone scan of patients with CSOM serves as an important guide in surgical approach for otolaryngologists, although there are limitations in evaluation of the CT results.</p>

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.

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.

Objective. Biofilms have been shown to play a major role in the pathogenesis of otolaryngologic infections. However, very limited studies have been undertaken to demonstrate the presence of biofilms in tissues from patients with chronic otitis media (COM) with or without cholesteatoma. Our objective is to study the presence of biofilms in humans with chronic suppurative and nonsuppurative otitis media and cholesteatoma.Study Design. In all, 102 tissue specimens (middle ear, mastoid tissue, and ossicle samples) were collected during surgery from 34 patients.Methods. The samples were processed for the investigation of biofilms by scanning electron microscopy (SEM).Results. Our research supports the hypothesis in which biofilms are involved in chronic suppurative otitis media, cholesteatoma, and, to a lesser degree, chronic nonsuppurative otitis media. There were higher rates in hypertrophic and granulated tissue samples than in normal mucosa. In addition, the presence of biofilms was significantly higher in the middle ear mucosa compared with the mastoid and ossicle samples.Conclusion. In the clinic, the careful use of topical or systemic antimicrobials is essential, and, during surgery, hypertrophic tissue must be carefully removed from normal tissue.
