<p class="abstract"><strong>Background:</strong> In chronic suppurative otitis media (CSOM), the success rate of tympanoplasty, can range from 35% to 92% and is influenced by a number of factors such as age of patient, size and site of perforation, status of ear, ossicular status and surgical technique. The middle ear risk index (MERI) of a CSOM patient is an effective numerical grading system helpful in predicting the outcome of surgery.  </p><p class="abstract"><strong>Methods:</strong> A prospective observational study was conducted in 50 patients over a period of 1 year including all cases of CSOM in age group of 18-55 years with conductive hearing loss that underwent tympanoplasty with or without cortical mastoidectomy and role of MERI was analysed for the outcome of the surgery.  </p><p class="abstract"><strong>Results:</strong> Successful graft uptake was seen in 92% cases while in 8% cases graft was rejected. Of these 46 cases, 32 cases had mild MERI score, 10 had moderate MERI score and 4 had severe MERI score. It was observed that higher the MERI score, lower the graft uptake.  </p><p class="abstract"><strong>Conclusions:</strong> Our study comprised of 50 patients of CSOM which were categorized into mild, moderate and severe on the basis of MERI score preoperatively. All the patients underwent tympanoplasty with or without cortical mastoidectomy and surgical outcome in terms of graft uptake was found to be significant. Higher the MERI score, lower was the graft uptake while lower the MERI score, higher was the graft uptake. Hence, MERI is a useful tool to ascertain the prognosis of tympanoplasty.</p>

Resistance To Penicillin

A total of 204 chronic middle ear effusions from 122 children have been studied. Bacteria were isolated from 30 effusions. The commonest species found were Strep. pneumoniae and H. influenzae. These are also the commonest organisms causing acute otitis media (AOM). A similar pattern of serotypes was also demonstrated. In vitro sensitivity testing showed that most of the organisms isolated were sensitive to most commonly-used antibiotics. The main exception was resistance to penicillin amongst strains of H. influenzae and Staph. aureus. It is suggested that some cases of chronic secretory otitis media (SOM) may arise as a result of incomplete resolution of AOM and that the use of penicillin to treat AOM may be one factor in this process.

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.

Aspiration of the exudate through open perforation was performed in 54 children with chronic suppurative otitis media. Eighty aerobic and 81 anaerobic isolates were recovered. Aerobic bacteria only were involved in 20 patients (37%), and anaerobic organisms only in seven (13%). Mixed aerobic and anaerobic isolates were recovered from 27 patients (50%). The most common bacteria isolated were anaerobic gram-positive cocci, Bacteroides melaninogenicus group, Pseudomonas aeruginosa, Klebsiella pneumoniae, and Staphylococcus aureus. There were 45 β-lactamase–producing bacteria (BLPB), 30 aerobes, and 15 anaerobes recovered from 38 patients (70%). β-Lactamase activity was detected in 30 of the 38 ear aspirates (79%) that contained BLPB. All but one of these organisms were in excess of 104 colony-forming units/mL. The detection of β-lactamase activity in the ear aspirates provides evidence of the role of BLPB in the failure of penicillin therapy to eradicate chronic ear infection.

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.
