Subcutaneous approximation suture for preventing soft tissue pollybeak deformity.
BACKGROUND
Pollybeak deformity due to abundant fibrosis formation in the supratip region after rhinoplasty is still a common problem. The aim of this study was to investigate the effects of a modified subcutaneous approximation suture on pollybeak deformity of soft tissue  origin.


METHODS
Three groups, each consisting of eight rabbits, were included in the study. Nasal skin was elevated with an open rhinoplasty approach in all groups. During closure of the skin, to minimize supratip dead space, a horizontal subcutaneous approximation suture  was used in group I, external tape fixation was used in group II, and no further action was taken for supratip skin approximation in the control group. Full-thickness supratip skin biopsy specimens reaching down to the underlying cartilage tissue were taken from each subject on the 60th day  after the operation. Thicknesses of subcutaneous scar tissues were measured histologically in all groups and compared.


RESULTS
The mean thickness of the subcutaneous scar tissues was significantly lower (0.98 ± 0.32 mm) in group I than in group II (1.65 ±  0.61 mm; p = 0.036) and the control group (1.72 ± 0.49 mm; p = 0.019). However, there were no significant differences between group II and the control group in the mean thickness of subcutaneous scar tissues (p = 1.000).


CONCLUSIONS
The findings of this study indicate  that the subcutaneous approximation suture is effective for preventing excessive scar tissue formation in the supratip area after rhinoplasty in rabbits. Further clinical studies are needed to determine its efficacy in humans.
