The treatments for bleeding sinuses vary based on the cause. Initial treatments for nosebleeds include self-treatments such as pinching the nose shut for 10 minutes while sitting upright and doctor-administered treatments such as nasal insertion of medication-saturated cotton balls, indicates Merck Manual. In cases where the underlying cause is sinusitis, treatments can include nasal irrigation, nasal or oral corticosteroids, and antibiotics for infection, according to Mayo Clinic. Treatment for allergies and other conditions may also be indicated, notes WebMD.
The sinuses are a series of hollow cavities in the cheekbones, behind the nasal cavity, behind the low-center part of the forehead, and between the eyes at the nasal bridge, according to WebMD. The sinuses themselves, since they are cavities in the skull, cannot technically bleed, but the tissue surrounding them can.
Individuals who experience nosebleeds four or more times a week should get evaluated to determine the cause, explains WebMD. Two-to-three recurring nosebleeds each month can indicate the presence of a chronic condition such as allergies. Causes of nosebleeds can be related to sinus problems such as acute and chronic sinusitis, but bleeding from this area can also be caused by systemic problems such as blood-thinning medications, low humidity that leads to cracking and bleeding of the nasal tissue, and many other conditions and environmental factors, states Mayo Clinic.
