[A comparison of the closed reduction of arytenoid dislocation under indirect and direct laryngoscope].
OBJECTIVE
To assess the curative effects of the dislocation of cricoarytenoid joint caused by intubation, indirect laryngoscope (IL) and direct laryngoscope (DL) were utilized to the closed reduction of the displaced arytenoid under local anesthesia.


METHODS
23 patients who underwent the reduction for dislocated arytenoid by IL or DL from Jan 1991 to Jun 2001 have been reviewed, the records were made as follows: The duration of the laryngeal injury; The number of times for the reduction; The side-effective following the treatment; The period of complete return of normal voice. The relation between the duration of the laryngeal lesion and the period of the voice rehabilitation has been studied.


RESULTS
13 patients and 10 patients were respectively arranged to perform the reduction by IL and DL. Except that a comparison on the times of the reduction is significantly different, the difference between IL group and DL group in the course and the period of voice rehabilitation, as well as sore throat after the manipulation are not significant. The patients' voice recovery is positively relative to their course, regardless of IL or DL, group.


CONCLUSIONS
The recovery of normal voice is obviously affected by the duration of arytenoid dislocation. The reduction by IL is as successful as by DL in the treatment of arytenoid dislocation. It is very suitable for the patient having his injury for a longer time to receive the reduction by DL.
