Until now few data on postoperative nasal respiration after nasal intubatio
n is known which is of special importance for surgery, where postoperative
intermaxillary fixation is necessary. This study was planned to acquire inf
ormation about nasal breathing during the first postoperative week. Twelve
patients created for mandibular retrognathism were examined repeatedly by w
ay of anterior active rhinometry, acoustic rhinometry, and rhinoresistometr
y before and after surgery over one week. In addition the subjective evalua
tion was checked on a visual analogue scale. Following intubation, signific
ant changes in "objective" and subjective measurements of nasal respiration
could be noted only on the second postoperative day. Comparing rhinomanome
tric and subjective data, a correlation could be found on postoperative day
two only. In this study group short-time nasal intubation had no significa
nt impact on postoperative respiration.
