Introduction: Olfactory neuroblastoma (ONB) is a malignant neoplasm that arises from the upper nasal vault.

Objective: We present a retrospective case series and clinical analysis of 12 ONB cases.

Gelatin Paste as an Alternative Cost-Effective Hemostatic Agent in Cranial Surgery: Doing More with Less.

Objective: To present an alternative cost-effective hemostatic agent (HA) for cranial surgery and to describe the technique to produce it.

Methods: This HA has been used in 3 reference centers over the last year during 230 procedures, including different types of pathology, such as skull base, oncology, vascular, and trauma, either for endoscopic or open approaches. This agent was made from a low-cost and worldwide-available gelatin foam which was mixed with saline solution in 2 syringes and connected by a 3-way stopcock, making a useful hemostatic paste.
