Multivariate analysis of the risk factors for temporary and permanent facial weakness.

Variable	Temporary facial weakness (n=46)a			Permanent facial weakness (n=6)b
	P value	Odds ratio	95% CI	P value	Odds ratio	95% CI
Revision surgery				0.01	17.1	2.4-123.9
Total parotidectomy	0.02	3.2	1.2-8.7	0.28	3.5	0.3-34.9
Specimen Volume (cc) >60	0.04	2.2	1.0-4.8	0.57	1.8	0.2-14.0

Dependent variables are temporary weakness vs no weakness (left) and permanent weakness vs no weakness (right).
