Aspirated debris in the middle ear was seen commonly in infants of over 28 weeks' gestation who bad suffered from intrapartum asphyxia, and was usually associated with evidence of pulmonary aspiration of amniotic squames. Most of these infants were stillborn or had died in the first 2 days of postnatal life, but amniotic debris persisted for a longer period in some, and in 8 cases it had excited a foreign body histiocyte reaction.The 17 cases with otitis media could be divided into two groups on the basis of middle ear findings: 11 cases with an admixture of amniotic debris and purulent exudate (P/A group) and 6 with purulent exudate only. The P/A group showed many clinical features in common with the infants of the aspiration group, with a high incidence of pregnancy complications and of need for prolonged ventilation.All 17 cases with otitis media had evidence of infection elsewhere, including pneumonia (12) and meningitis (6). In 13 of the 14 cases with positive bacteriology, the organisms cultured were Gram-negative (Esch. coli or Pseudomonas aeruginosa).It is argued that amniotic debris may be aspirated into the middle ear in asphyxiated babies and this may explain some of the unusual metaplastic changes noted in the epithelium of the middle ear cavities. Furthermore, stagnant amniotic debris may become secondarily infected by organisms, particularly if the infant requires ventilation.While infections of the middle ear are known to be common in older children, relatively little attention has been paid to similar infections occurring in newborn infants. This is surprising since it has been shown by many writers that middle ear infections are common in this age group (Benner, 1940;Allen, Morison, and Rutherford, 1946;McLellan et al., 1962 The left middle ear cavity was examined using the procedure described by Morison (1970). Smears of any fluid or exudate present were taken, and whenever purulent exudate was present bacteriological samples were taken for culture. The petrous temporal bone on the right side was dissected away from the skull so as to include the terminal portion of the extemal auditory canal and the tympanic membrane in continuity with the 872 on 11 May 2018 by guest.

“…A number of authors have reported that amniotic fluid is commonly present in the middle ear of the newborn, 8,10,13,[18][19][20][21][22] based on their observation that amniotic cellular debris was observed in this site at birth as well as at 3 weeks, 10 4 weeks, 20 and even at 34 weeks. 22 Northrup et al 13 found evidence of amniotic fluid in 90 percent of newborns and in 55 percent of infants aged 31 to 70 days.…”

“…36 When organ isms were found in cases where fetal mem branes were intact, 36,39 the possibility of a blood-borne route of infection has been raised. 36 Since amniotic debris commonly en ters the middle ear in the perinatal period, 10,13,18,19,21,22 a healthy mucous membrane 40,41 and good eustachian tubal function [42][43][44] would seem important in re moving this contamination before a for eign body reaction or tissue infection could take place. Perhaps these functions are less adequate in some individuals, rendering them more susceptible to the early devel opment of otitis media.…”

“…It is likely that the high incidence of middle ear problems in the ICN contributes significantly to the number of initial screening failures. ICN neonates are clearly at high risk for otitis media, with incidence figures ranging as high as 67 percent (McLellan et al, 1962). Therefore, it is likely that much of the discrepancy between initial and follow-up ABR screening tests is related to transient middle ear problems.…”
