The injections are quick-acting, and symptoms usually go away within one to two weeks. As the condition improves, doses are reduced to weeks and then can be given monthly. Intramuscular therapy leads to more rapid improvement and should be considered in patients with severe deficiency or severe neurologic symptoms. Treatment should begin rapidly for severe neurological symptoms, as some changes can become permanent. In some individuals lifelong treatment may be needed. Erythropoiesis-stimulating agents
The objective for the administration of an erythropoiesis-stimulating agent (ESA) is to maintain hemoglobin at the lowest level that both minimizes transfusions and meets the individual persons needs. They should not be used for mild or moderate anemia. They are not recommended in people with chronic kidney disease unless hemoglobin levels are less than 10 g/dL or they have symptoms of anemia. Their use should be along with parenteral iron. The 2020 Cochrane Anaesthesia Review Group review of Erythropoietin plus iron versus control treatment including placebo or iron for preoperative anaemic adults undergoing non‐cardiac surgery  demonstrated that patients were much less likely to require red cell transfusion and in those transfused, the volumes were unchanged (mean difference -0.09, 95% CI -0.23 to 0.05). Pre-op Hb concentration was increased in those receiving high dose EPO, but not low dose. Hyperbaric oxygen
Treatment of exceptional blood loss (anemia) is recognized as an indication for hyperbaric oxygen (HBO) by the Undersea and Hyperbaric Medical Society.
Post-surgical: after frontal sinus reconstruction

Diagnosis
Diagnosis is suspected clinically and is confirmed using cross sectional imaging of the sinuses and brain. The patient typically presents with a headache overlying the frontal sinuses and an associated forehead swelling. This is often preceded by a history of chronic rhinosinusitis.Plain X Rays can be used to demonstrate the location of this swelling, but the gold standard for diagnosis is a cross sectional CT scan of the sinuses and brain, aided by contrast to delineate the abscess itself. Treatment
The patient requires admission for intravenous anti-microbial treatment. Definitively, the abscess is drained via a combination of open and/or endoscopic approaches by an otolaryngologist, with the exact approach dependent on surgical skill set. At the very least, the abscess is trephined externally as an emergency. Any associated frontal sinus table fracture can be managed electively. Intracranial extension requires referral to the neurosurgery. References
