[Otorhinological evaluations of patients undergoing rapid disjunction of the median palatine suture].

Seven young patients, who had been diagnosed to be oral breathers by an orthodontist, have been submitted to an ETN specialist examination, before and after the rapid expansion of the mid-palatal suture. Five of these patients had an actual reduction of nasal breathing capacity. Four patients presented a significant enlargement of the adenoids. One patient showed a transmission auditive deficiency. The ETN examination, two months after the maxillary expansion, has permitted to find out that all the patients who had an impaired nasal breathing before the maxillary expansion, had normalized their respiratory capacity. Moreover, those subjects who had enlarged adenoids, showed a normal adenoids volume in the second ETN examination. Finally also the patient with an auditive deficiency presented a normalization of this function at the second ETN examination.
