Abstract
There has been few investigations about the distributions and the change of cell number of indigenous nasal microbiota in relation to palate plasty of cleft palate.
This paper deals with the ecolo g ical study of the distribution and the change of cell number of microbiota in the nasal cavity, on the dorsum of the tongue- and buccal mucous membrane in connection with palate plasty.
It seems to be one of the various factors that exert influence on nasal and oral microbial flora. Subjects studied consisted of 28 patients with complete palatal clefts, taking palate plasty from 1 year 2 months to 1 year 4months.
This experiments have produced the following results.
1) Before operation, the nasal flora resembled to the oral microbial flora but the aerobic organisms became predominant in place of obligatory or facultative anaerobic organisms, after operation it was silimar to normal nasal flora.
2) There was a similarity in oral microbial flora between the patients with palatal clefts and normal ones. But the former's got. much closer to the normal oral flora after operation, the cell number showed little change.
3) The cell number of streptococci was the most predominant either before or after operation in nasal and oral cavity, however, the number of Staphylococcus aureus was the lowest. Therefore, the author thought that we ought to take into account the above mentioned facts in order to prevent the infection during pre- and post-operation.
