The Effectiveness of Modified Cottle Maneuver in Predicting Outcomes in Functional Rhinoplasty

Table 1

Comparison of pre- and postoperative nasal airflow improvement scores on a 10-point visual analog scale for batten and spreader grafts. The preoperative score is obtained while performing the modified Cottle maneuver for both the internal and external nasal valve assessments.

Operative technique	Predicted mean improvement	Mean postoperative improvement	Difference in means	Correlation (>0.05 is significant)
Overall ()	4.1 (SD ± 2.3)	4.5 (SD ± 2.2)		0.51; ()
Internal nasal valve spreader graft ()	3.0 (SD ± 1.8)	5.2 (SD ± 2.8)		0.80; ()
External nasal valve batten graft ()	3.7 (SD ± 2.3)	4.3 (SD ± 2.0)		0.50; ()
