[Clinical observation and anatomical analysis of middle turbinate and ethmoidal internal wall moved to external side after microsurgery].

OBJECTIVE

To assess the effect of middle turbinate (MT) and ethmoidal internal wall(EIW) moved externally after microsurgery.

METHODS

Twenty-four cases (45 sides) were followed-up endoscopically for (16.3 +/- 9.3) months. Thirteen cases (24 sides) were observed by CT scans. Three cadaver heads were measured for anatomical analysis.

RESULTS

Forty-one (91%) of 45 sides obtained better olfactory function after operation. Twenty-two (91%) of 24 sides were found to have better CT changes in sinus ventilation as compared with preoperative CT scans. The gap between the MT and EIW to the orbital wall was (12.0 +/- 1.0) mm, while that between the ethmoidal bulla and processus uncinatus was only (2.3 +/- 0.6) mm as revealed in the autopsy.

CONCLUSION

MT and EIW moderately moved suitably to externally had no bad effect on sinus ventilation, and it improved olfaction.
