[Early diffuse hypertrophic osteitis recurrence. Unexpected and consternating development after a large évidement cavity. Apropos of 15 cases].
The authors report 15 cases collected over a period of 13 years (1972 - 1984) of a particularly serious eventuality affecting certain evacuation cavities: Early recurrence of diffuse hypertrophic osteitis (E.R.D.H.O.). This is a rare complication, occurring in 1.5% of cases of chronic otitis. However, the fact of having operated upon 7 cases in 1984 alone, whilst during the previous 12 years, only 8 had been seen, raised the alarm. The classical pattern of this complication occurs in 3 stages, each involving surgical operation: at the outset, chronic otitis with cholesteatoma or osteitis, most often mixed, for which an "inadequate" surgical procedure is performed. then, after a variable period which may exceed 10 years, a very large evacuation cavity was created by the authors. finally, 3rd and final stage: within 6 months, this cavity filled progressively and, at operation, the authors discovered a cavity virtually completely filled with a "fantastic" "moist sugar" osteitis, requiring a new evacuation cavity, even larger than that created before. In all cases, a successful result was obtained within a varying period, sometimes accompanied by spectacular improvement in general condition. The most plausible etiopathogenic hypothesis advanced to attempt to explain this phenomenon is that of secondary infection by a varied microbial flora, including, on the one hand, aerobic organisms usually discovered in such cases (pseudomonas pyocyaneus, proteus mirabilis) and, secondly, this being of essential importance, "anaerobic" bacteria, the bacteriological diagnosis of which requires application of a strict protocol. The authors have taken three decisions following their bibliographic investigations.(ABSTRACT TRUNCATED AT 250 WORDS)
