The aerobic microorganisms present in 57 MEs of 40 children with C Supp OM without cholesteatoma were evaluated. Specimens were taken directly from the ME through a patent perforation or tympanostomy tube and cultured using standard techniques. Twenty-six organisms were identified, with Pseudomonas aeruginosa being the most prevalent (65% of ears) and the only organism in 30% of ears. The initial treatment of all patients was intravenous administration of an antimicrobial selected on the basis of culture and susceptibility reports. This treatment was successful in all but four children, who subsequently required tympanomastoid surgery. These results indicate that the microbiology of C Supp OM is similar to that in patients with cholesteatoma. However, based on the results of culture and susceptibility studies, medical therapy provides a viable alternative to major mastoid surgery in the management of C Supp OM without cholesteatoma.

Background: Chronic suppurative otitis media (CSOM) is one infectious disease of the middle ear, most commonly caused by Pseudomonas aeruginosa. A high number of patients come to the ENT outpatient clinic with active benign type of CSOM. The bacteria Pseudomonas aeruginosa is capable of producing biofilm which protects itself from penetration of antibiotics, and therefore creates resistance towards antibiotics and difficult to eradicate. Objective: The aim of this study was to compare the sensitivity levels of chloramphenicol, polymyxin-neomycin, cyprofloxacin and ofloxacine against Pseudomonas aeruginosa in patients with active benign type CSOM in ENT clinic. Method: The method used was across sectional study on 25 patients, from August 2010 until December 2010. Samples were taken withear swab and then put on sensitivity test to chloramphenicol, polymyxin-neomycin, cyprofloxacin andofloxacine using the diffusion disc method. The analysis used in this study was Cochran test. Results: Results showed a significant difference in sensitivity among chloramphenicol (38,70%), polymyxinneomycin(83,87%),cyprofloxacin(90,32%)andofloxacin(58,06%)withp=0,000(p<0,05).PostHocanalysisusing the Mc Nemar indicated that there were significant differences in sensitivity betweenpolymyxin-neomycin to chloramphenicol with p=0,000 (p<0,05), ciprofloxacin to chloramphenicol andciprofloxacin to ofloxacine with p= 0,002, but there were no significant differences between cyprofloxacinto polymyxin-neomycin with p=0,687, polymyxin-neomycin to ofloxacin p=0.057 and ofloxacin tochloramphenicol p=0,109.   There were significant differences in antibiotic ear dropssensitivity to Pseudomonas aeruginosa in patients with active benign type of CSOM. Cyprofloxacin andpolymyxin-neomycin were more sensitive than ofloxacin and chloramphenicol. Keywords: Pseudomonas aeruginosa, active benign type of chronic suppurative otitis media, antibioticear drops.  Abstrak :  Latar belakang: Otitis media supuratif kronik (OMSK) merupakan penyakit infeksi kronik telinga tengah yang sering dijumpai di klinik THT. Penyebab tersering OMSK adalah bakteri Pseudomonasaeruginosa. Pseudomonas aeruginosa mempunyai kemampuan untuk membentuk biofilm yangmelindunginya dari penetrasi antibiotik sehingga menimbulkan resistensi terhadap antibiotik dan sulituntuk eradikasinya. Tujuan: Untuk mengetahui perbandingan tingkat sensitivitas kloramfenikol,polimiksin-neomisin, ciprofloksasin dan ofloksasin terhadap isolat Pseudomonas aeruginosa padapasien OMSK benigna aktif di klinik THT RSMS. Metode: Metode yang digunakan adalah crosssectional terhadap 29 pasien OMSK di klinik THT RSMS periode bulan Agustus 2010 - Desember2010. Pengambilan sampel dilakukan dengan swab telinga. Uji sensitivitas terhadap kloramfenikol,polimiksin-neomisin, ciprofloksasin dan ofloksasin dilakukan dengan metode cakram secara difusi.Analisis yang digunakan dalam penelitian ini adalah Cochran dan analisis post hoc. Hasil: Didapatkansensitivitas kloramfenikol sebesar 38,70%, polimiksin-neomisin sebesar 83,87%, ciprofloksasin sebesar90,32% dan ofloksasin sebesar 58,06% dengan p=0,01 (P<0,05), yang menunjukkan adanya perbedaansensitivitas yang bermakna antara kloramfenikol, polimiksin-neomisin, ciprofloksasin dan ofloksasinterhadap Pseudomonas aeruginosa. Analisis post hoc menggunakan Mc Nemar menunjukkan bahwaterdapat perbedaan sensitivitas yang bermakna antara tetes telinga polimiksin-neomisin terhadapkloramfenikol, dan ciprofloksasin terhadap kloramfenikol p=0,000 (p<0,05), serta terdapat perbedaanyang bermakna antara tetes telinga ciprofloksasin terhadap ofloksasin, p=0,002, tetapi tidak terdapatperbedaan yang bermakna antara ciprofloksasin terhadap polimiksin-neomisin, p=0,687, polimiksinneomisinterhadap ofloksasin p=0,057, dan kloramfenikol terhadap ofloksasin p=0,109. Kesimpulan:Terdapat perbedaan sensitivitas yang bermakna tetes telinga antibiotik terhadap Pseudomonas aeruginosa pada pasien OMSK benigna aktif. Ciprofloksasin dan polimiksin-neomisin tetes telinga mempunyai sensitivitas yang lebih baik dibanding ofloksasin dan kloramfenikol.

Medical management of chronic suppurative otitis media without cholesteatoma in children was shown recently to be efficacious. We undertook a prospective study in order to determine 1) the organisms associated with the disease and their sensitivity to various antibiotics and 2) their association with clinical variables. Pseudomonas was isolated from 84% of the patients, enteric gram-negative bacilli from 32%, Staphylococcus aureus from 20%, streptococci from 14%, and Hemophilus influenzae from 15%. Pseudomonas aeruginosa was the sole isolate in 48 of the 128 patients (38%). The sensitivity of P aeruginosa (78 isolates) was 100% (of isolates) to mezlocillin and ciprofloxacin, 99% to tobramycin and ceftazidime, 97% to piperacillin, 94% to gentamicin, and 78% to ceftriaxone. The isolated organisms and their sensitivity to antibiotics were not associated with age, sex, duration of otorrhea, or the presence of granulation tissue or polyps. We believe that our data may contribute to the appropriate choice of antibiotics when nonsurgical management of chronic suppurative otitis media without cholesteatoma is considered.

AbstractMeningo-encephalocoele of the temporal bone, also known as fungus cerebri, is a rare occurrence in clinical practice. We present a series of 13 patients with chronic otitis media who suffered brain herniation into the mastoid cavity. We also discuss the presentation and management of brain herniation with or without cerebrospinal fluid leak.Study design:Retrospective.Methods:Among 963 cases undergoing revision mastoid surgery, 13 patients suffered brain herniation. These cases were identified and analysed.Results:All 13 patients' initial diagnosis was chronic suppurative otitis media with cholesteatoma, and all had undergone previous mastoid surgery resulting in a defect in the tegmen and weakening of the dura mater. The revision procedures performed included 10 (76.9 per cent) modified radical mastoidectomies without ossicular chain reconstruction and one (7.6 per cent) modified radical mastoidectomy with ossicular chain reconstruction; two (15.3 per cent) patients required a blind sac closure. Brain herniation and/or cerebrospinal fluid leak were repaired by a transmastoid ± minicraniotomy procedure.Conclusions:Injury to the tegmen and dura should be avoided during surgery for chronic middle-ear disease. Cerebrospinal fluid leaks, if encountered, should be managed in the same surgical session. The transmastoid approach is helpful in repairing defects smaller than 1 cm in diameter, whereas the combined transmastoid-minicraniotomy approach provides good access when closing defects larger than 1 cm in diameter and also enables auto-calvarial grafting.

Abstrak Operasi mastoid berkembang sebagai penanganan terhadap Otitis Media Supuratif Kronik (OMSK). Mastoidektomi revisi dilakukan bila tujuan operasi pertama tidak tercapai. Kegagalan operasi mastoid bisa disebabkan oleh berbagai hal, diantaranya penanganan air cell yang tidak adekuat, facial ridge yang tinggi, kegagalan membuang semua kolesteatom, meatoplasti yang tidak adekuat dan ketidakpatuhan pasien untuk kontrol setelah operasi. Operasi mastoid revisi biasanya lebih sulit dan berbahaya karena anatomi telinga tengah menjadi tidak jelas, landmark dapat hilang dan struktur berbahaya sudah terpapar. Dilaporkan satu kasus operasi mastoid revisi pada seorang laki-laki berumur 25 tahun, yang ditatalaksana dengan timpanomastoidektomi dinding runtuh.Kata kunci: otitis media supuratif kronik, mastoidektomi revisi, kolesteatom, meatoplasti Abstract Surgery of the mastoid developed as a treatment for chronic suppurative otitis media. Revision mastoid surgery done if the aim of first surgery not achieved. Failure of  mastoid operation may caused by many things, including handling of air cells are not adequate, high facial ridge,  failure to remove all cholestetoma  meatoplasty in adequate and non adherence of patient to control after surgery. Revision  mastoid surgery is usually more difficult and dangerous, because anatomy of the middle ear may be altered, some of the important landmarks can be loss and dangerous  structure has been exposed. It was reported one case revision mastoid surgery in a man aged 25 years old, management with canal wall down tympanomastoidectomy.Keywords: chronic suppurative otitis media, revision mastoidectomy, cholesteatoma, meatoplasty

BACKGROUND: Chronic Suppurative Otitis Media (CSOM) causes hearing impairment and frequently occurred in low-income country where medical care and personal hygiene are poor. Staphylococcus aureus and Pseudomonas aeruginosa are the most common cause of CSOM. We investigated prevalence and antimicrobial susceptibility of S. aureus and P. aeruginosa from tubotympanic CSOM patients in tertiary hospital, Purwokerto, Indonesia in 2016-2017.METHODS: Ear swab specimens were collected from patients with tubotympanic CSOM. S. aureus and P. aeruginosa were isolated and identified by culture, matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS), and molecular tools. Antimicrobial susceptibility testing was performed using the disk diffusion method.RESULTS: Out of ear swabs from 34 patients with tubotympanic CSOM, P. aeruginosa and S. aureus were identified in 35%patients. No Methicillin-resistant S. aureus (MRSA) strain was found from the ear swabs of the patients with tubotympanic CSOM. Bacterial identification using the MALDI-TOF MS was concordantly with culture and molecular tools. All S. aureus isolates showed full susceptibility to cefoxitin and trimethoprim-sulphamethoxazole. Resistance to tetracycline was common with only 64% of S. aureus strains being susceptible. Meanwhile, all P. aeruginosa strains were susceptible to cefepime, cetazidime, meropenem, gentamicin, and tobramycin.CONCLUSION: S. aureus and P. aeruginosa are found in patients with tubotympanic CSOM and still susceptible to different antibiotic agents. MALDI-TOF MS demonstrate rapid, accurate and robust to detect S. aureus and P. aeruginosa.KEYWORDS: Staphylococcus aureus, Pseudomonas aeruginosa, chronic tubotympanic suppurative otitis media
