Abstract

Currently available intrathymic injection techniques cause postoperative complications or difficulties in equipment acquisition. Here, we describe a standardized intrathymic injection protocol that requires only basic equipment with a minimally invasive procedure. We detail steps to identify injection sites for intrathymic delivery. We then describe how to visualize a successful intrathymic injection by including Indian ink in the injected solution. For complete details on the use and execution of this protocol, please refer to Tsai et al. (2022).¹.
