Reduction of Middle Turbinate Can Cause Nose Bleed?

Yes, it is possible that turbinate surgery can lead to more nose bleeds. It sounds like you need an evaluation by your surgeon.

Although unusual, epistaxis can occur after surgery from turbulent airflow or uncompensated increased airflow causing the nasal mucosa to dry and crack (similar to chapped lips). This is more common in dryer climates and in the winter. The frequent utilization of nasal saline spray usually alleviates this. If it persists despite proper moisturization a thorough nasal examination by an Otolaryngologist is indicated.
