The Efficacy of Open Mastoidectomy Versus Mastoidectomy with Temporalis Fascia Flap Obliteration.
Chronic suppurative otitis media is a perforated tympanic membrane with persistent drainage of pus from the middle ear lasting more than 2-weeks.
The global burden of illness from CSOM estimated to involve about 65 to 330 million individuals with draining ears, 60% of them were suffers from significant hearing impairment.
Ninety percent of burden is borne by developing countries, in Southeast Asia, the Western region of Africa. CSOM can occur with or without cholesteatoma, and the clinical history of both conditions can be very similar.
The treatment plan for cholesteatoma always includes tympanomastoid surgery with medical treatment as an adjunct. The yearly incidence of CSOM, to be 39 cases per 100,000 persons in children and adolescents aged 15-years and younger.
In Israel, only 0.039% of children are affected. Other populations at increased risk include children from Guam, Hong Kong, South Africa, and the Solomon Islands.
The anatomy and function of the eustachain tube play a significant role in the increased risk. The eustachain tube is wider and more open in these populations than in others, thus placing them at increased risk for nasal reflux of bacteria common to acute otitis media and recurrent acute otitis media and leading to more frequent development of CSOM.
Certain population subsets are at increased risk for developing CSOM. The Native American and Eskimo populations demonstrate an increased risk of infection.
The prevalence of CSOM appears to be distributed equally between males and females. Exact prevalence in different age groups is unknown; however, some studies estimate the yearly incidence of CSOM to be 39 cases per 100,000 in children and adolescents aged 15-years and younger
