BackgroundOtitis media (OM) is a leading cause of health care visits and drugs prescription. Its complications and sequelae are important causes of preventable hearing loss, particularly in developing countries. Within the Global Burden of Diseases, Injuries, and Risk Factors Study, for the year 2005 we estimated the incidence of acute OM, chronic suppurative OM, and related hearing loss and mortality for all ages and the 21 WHO regional areas.MethodsWe identified risk factors, complications and sequelae of OM. We carried out an extensive literature review (Medline, Embase, Lilacs and Wholis) which lead to the selection of 114 papers comprising relevant data. Data were available from 15 of the 21 WHO regions. To estimate incidence and prevalence for all countries we adopted a two stage approach based on risk factors formulas and regression modelling.ResultsAcute OM incidence rate is 10.85% i.e. 709million cases each year with 51% of these occurring in under-fives. Chronic suppurative OM incidence rate is 4.76‰ i.e. 31million cases, with 22.6% of cases occurring annually in under-fives. OM-related hearing impairment has a prevalence of 30.82 per ten-thousand. Each year 21thousand people die due to complications of OM.ConclusionsOur study is the first attempt to systematically review the available information and provide global estimates for OM and related conditions. The overall burden deriving from AOM, CSOM and their sequelae is considerable, particularly in the first five years of life and in the poorest countries. The findings call for incorporating OM-focused action within preventive and case management strategies, with emphasis on the more affected.

“…This is comparable to finding of Ahmed M. Alabbasi et al 8. In the study of 120 cases of CSOM, they found conductive hearing loss in 55.5% cases, mixed hearing loss in 44.3% cases and sensory neural in 16.6% cases. Ramanuj Bansal 15 in a study of 758 cases, found otitis media (57.25%) is the commonest cause and conductive hearing loss (86.17%) in otitis media is the commonest type. B. M. Minja 16 in a study of 189 cases of CSOM found the prevalence of hearing loss in CSOM was 89 (47%).…”

Suppurative otitis media is a common occurrence and so are its complications. Its various complications are of frequent occurrence in otorhinolaryngology clinics. The incidence of extracranial ones are still posing a problem to the otologists Present work has been, undertaken from September 2010 to September 2012 to study the incidence of extracranial complications in relation to suppurative otitis media and to study the clinical presentation and pathology of extracranial complications of suppurative otitis media. Total 6130 cases of suppurative otitis media were observed (23.96%). Out of these patients 4890 cases (19.11%) were having chronic suppurative otitis media (CSOM) and 1240 cases (4.85%) had acute suppurative otitis medi (ASOM).In the present study, it is seen that 23.96% of total patients were having suppurative otitis media. The incidence of complications due to ASOM is 1.45%. Mastoiditis comprises of 59.35% of total extracranial complications and is the commonest in the present series followed by subperiosteal abscess, labyrinthitis and facial palsy. The prevalence can be decreased by means of health awareness regarding how to take care of the ear and when to report the physician. KEYWORDS: Extracranial Complications, Middle ear infections, Clinicopathological study. INTRODUCTION:Suppurative otitis media is a common occurrence and so are its complications. The growing children are the worst sufferers of complications. Though the incidence of intracranial complications has appreciably reduced, the incidence of extracranial ones is still posing a problem to the otologists. Infections of middle ear cleft are very common in India. 40% of attendance in E.N.T. department of general hospitals consists of cases of infections of middle ear cleft. Contribution towards the treatment of this malady has yet to be achieved to a standard, in developing countries. India being a subcontinent where 80% of the population live in rural areas in the altar of poverty, ignorance, and illiteracy and lag behind in facilities of transport and early specialist advice.Thus patients attend outdoor chiefly with complications of suppurative otitis media. Further the indiscriminate use of antibiotics and ear drops have produced resistance strains of bacteria, the treatment of suppurative otitis media and its complications have undergone a revolutionary change in the hands of otologist. The ultimate aim of the otologist is to have an ear dry, socially useful and safe from the threatening complications. The present work has been designed to stress upon the clinico-pathological evaluation of extracranial complications of middle ear infections amongst the patients attending E.N.T. department of V.S.S. Medical College Hospital, Burla which is the tertiary apex hospital in whole of the western Odisha for specialized consultations so that we can predict the eventuality and also create the awareness among the public to prevent the complications.

“…In India, OM is the most common etiological factor (57.25%) of hearing loss, with the majority (62.2%) in the 0-20 years age group [ 3 ]. The prevalence of chronic suppurative OM among children is significantly higher in urban slums (9.9%) as compared to rural areas (7%) and nonslum urban locales (4.6%) [ 4 ].…”

Objectives: Chronic otitis media (COM) remains a global disease, a burden, and a challenge. Predicting its treatment’s postoperative success based on clinical presentation has not been reported, particularly for the mucosal (tubotympanic/safe) type. Methods: A prospective descriptive study of patients with mucosal-type COM was done to identify clinical predictors of improved postoperative hearing outcomes and successful graft uptakes. Results: Among the 110 ears studied, tympanoplasty was performed in 76 and cortical mastoidectomy with tympanoplasty in 34, based on six weeks of discharge-free or persistent discharge, respectively; all were treated with postoperative intranasal steroid spray. Eustachian tube dysfunction was noted in 96.4%. All patients with a history of ear discharge over five years had ossicular discontinuity, and those with persistent discharge had nonpatent aditus. Normal postoperative hearing was attained in most patients with less than one year of ear discharge. Surgical intervention within a year achieved normal hearing and graft success of 100% with type I tympanoplasty using the fascia alone in discharge-free ears and cortical mastoidectomy with tympanoplasty using cartilage-fascia graft in discharging ears, despite Eustachian tube dysfunction. In the latter group, graft success in type II tympanoplasty was 76.9%. Conclusion: Ear discharge is the prime predictor of postoperative success in mucosal-type COM, as its duration and persistence dictate the time and type of surgical intervention. Duration of more than five years is directly proportional to pre-operative hearing loss with ossicular involvement and inversely proportional to postoperative hearing improvement, necessitating early surgical intervention, despite it being the mucosal or “safe type.” Ear discharge-free for six weeks is an indicator of tympanoplasty. Persistent ear discharge, despite nonotogenic confounders, suggests aditus nonpatency, indicates the need for cortical mastoidectomy, and necessitates achieving its patency along with tympanoplasty. A surgical decision-making algorithm for the best possible surgical outcome in the chronic mucosal type of OM is also suggested.
