You cam start alkaline nasal washes 48 - 72 hours after surgery. Use Normal Saline for the nasal washes as household salt contains anti-caking agents and high concentration of salt will also damage the delicate nasal mucosa. If the nasal clots and debris persists, go for a follow up to your surgeon for cleaning he nose with endoscopy
and suction. These problems usually persist for up to four weeks post-op. Total healing of the internal surgical wounds can take up to six months depending upon the extent of surgery, though you may not feel any discomfort on the outside.
