Experimental surgical treatment for recurrent epistaxis.
OBJECTIVE
To evaluate a new technique of submucosal supraperichondrial (SMSP) dissection of the nasal septum and its subsequent effect on the vascularity of the mucosa. A reduction may decrease the rate of recurrent anterior epistaxis.


METHODS
The procedure was performed on one side of the nasal septum of 16 laboratory rabbits. After healing occurred 3 months later, the animals' septa were excised and stained. Both sides were then compared by using standardized microscopic field analysis.


RESULTS
The reduction in both the number of blood vessels on the operated side of the septum and the proportion of area occupied by these vessels was statistically significant (P < .004).


CONCLUSIONS
This technique led to a reduction in the vascularity of the nasal septal mucosa, 3 months after dissection was performed. Healing, which occurs by a process of fibrosis, yielded a less vascularized tissue. Although further laboratory and clinical assessment is recommended, this technique may prove valuable in reducing the rate of recurrent anterior epistaxis.
