A dorsal approach for the removal of the nasal septum in the horse.

The research proves the efficacy of a dorsal approach for removing nasal septum in adult horses which had reduced airflow due to septum deviation or thickening (caused by trauma or neoplasia). This technique facilitated excellent access to the septum, controlled hemorrhage, and resulted in good cosmetic outcomes, allowing horses to return to their previous activities without limitations.

Research Methodology

• The study was conducted retrospectively on four client-owned adult horses that required nasal septum resection due to reduced airflow caused by septal deviation and/or thickening. This thickening was brought about by traumatic injury or tumors (neoplasia).
• The surgical process chosen was a dorsal nasal bone flap approach, where a bone flap is made on the back or upper side of the equine nasal bone to gain access to the septum.
• The horse’s clinical signs and diagnostic results were recorded preoperatively, while any complications occurring during or after the surgery were documented for study.
• Post-surgery, follow-up information was acquired through telephone interviews with horse owners or further clinical examination.

Research Results

• The forwarded technique was able to entirely remove the problematic part of the nasal septum in all four horses.
• The dorsal nasal bone flap approach provided excellent access to the septum, allowing immediate control of bleeding. No blood transfusion was required in any of the surgeries.
• The owners rated the cosmetic results of the procedure as good to excellent. Post-surgery, the horses were able to resume their previous level of work without any perceived limitations linked to breathing or airway function.

Research Conclusions

• The dorsal nasal bone flap approach to nasal septum resection offers ideal observation of the abnormal septum and provides exposure that makes the removal of nasal lumps simpler, with minimal complications.
• Considering the minimal bleeding, good cosmetic outcomes, and quick return to function, this technique is recommended for horses needing a nasal septum resection.
