Hemostasis in endoscopic sinus and skull base surgery.

PURPOSE OF REVIEW

Bleeding during endoscopic endonasal procedures can quickly obscure critical anatomic landmarks. This increases both the difficulty of the surgical procedure and the risk of complications faced by the patient. As the indications for surgical management of sinonasal pathology grow, it is important to review techniques to minimize bleeding and facilitate safe surgery.

RECENT FINDINGS

Evidence continues to accumulate for best practices in the surgical management of sinonasal disease. Recently, international guidelines have attempted to summarize this body of evidence, lending further support to several interventions which have been advocated as methods to decrease bleeding during endoscopic endonasal surgery. Additional studies have specifically investigated the safety of certain commonly employed techniques. The utility of preoperative corticosteroid therapy and the use of total intravenous anesthetic techniques in increasingly validated. Further evidence supports the safety of reverse Trendelenburg positioning for surgical management of inflammatory disease.

SUMMARY

Recent wide scale systematic review of the literature regarding perioperative and intraoperative management of hemostasis has reinforced the utility of certain interventions, while others remain ambiguous.
