ABSTRACT

BACKGROUND:

Because of its unique advantages, frontal expansion has become a common tool for Asian nasal reconstruction, but it has the limitations of prolonging the duration and pain in the expansion area. Based on the fact that the denervation effect of botulinum toxin type A (BTX-A) has been widely used in the reconstruction of superficial organs, we hypothesized that BTX-A would shorten the length of nasal reconstruction sequence and alleviate the discomfort of patients.

METHODS:

A comparative retrospective study was conducted of consecutive patients underwent sequential treatment of nasal reconstruction between June 2010 and July 2012. Data on demographics, BTX-A injection plan and expansion duration were collected and analyzed. Phased pain intensity outcomes were evaluated by visual analogue scale (VAS). Photographs were collected during the follow-up period.

RESULTS:

Thirty patients were enrolled in the study; 15 (50%) with and 15 (50%) without BTX-A pre-injection. Demographic data were homogeneous. The duration of the observation group (BTX-A pretreated) (133.87 ± 13.64 days) was significantly shortened versus the control group (164.27 ± 14.08 days, P<0.001). At the initial stage, no significant difference was found in the VAS scores (P=0.64). At the medium stage, the VAS score of the observation group (2.07 ± 0.80) was significantly lower than the control group (3.00 ± 0.53, P<0.01). At the terminal stage, the VAS score of the observation group (1.93 ± 0.59) was significantly lower than the control group (2.73 ± 0.70) but with a narrower disparity.

CONCLUSION:

Pre-injection of BTX-A is effective in shortening the duration of the expansion phase, as well as relieving the pain associated with expansion.
