Summary
A new submucosal supraperichondrial (SMSP) dissection technique significantly reduced nasal septal mucosal vascularity in rabbits. This finding suggests potential for decreasing recurrent anterior epistaxis rates.
Area of Science:
- Otorhinolaryngology
- Surgical Innovation
- Nasal Anatomy
Background:
- Recurrent anterior epistaxis is a common clinical challenge.
- Current treatments for epistaxis may have limitations.
- Understanding nasal mucosal vascularity is crucial for managing epistaxis.
Purpose of the Study:
- To evaluate a novel submucosal supraperichondrial (SMSP) dissection technique for the nasal septum.
- To assess the impact of SMSP dissection on nasal mucosal vascularity.
- To explore the potential of SMSP dissection in reducing recurrent anterior epistaxis.
Main Methods:
- The SMSP dissection was performed on one side of the nasal septum in 16 laboratory rabbits.
- After a 3-month healing period, septa were excised and stained.
- Microscopic field analysis was used to compare vascularity between operated and non-operated sides.
Main Results:
- A statistically significant reduction in blood vessel number was observed on the operated side (P < .004).
- The proportion of mucosal area occupied by blood vessels was also significantly reduced (P < .004).
- Healing occurred via fibrosis, resulting in less vascularized tissue.
Conclusions:
- The SMSP dissection technique effectively reduces nasal septal mucosal vascularity.
- The observed reduction in vascularity is attributed to healing by fibrosis.
- This technique shows promise for managing recurrent anterior epistaxis, warranting further investigation.
