Source: Olmstead, D. N., et al., Facial Nerve Axotomy in Mice: A Model to Study Motoneuron Response to Injury. J. Vis. Exp. (2015).This video demonstrates the facial nerve crush procedure in a mouse, where blunt dissection through key landmarks exposes the facial nerve trunk at the stylomastoid foramen. Forceps are then used to compress the nerve trunk, inducing axonal damage and disrupting neuronal signal transmission.

Integrating information technology into business-to-business (B2B) marketing has significantly transformed how companies interact and transact. A crucial development in this domain is e-procurement, which has become standard practice for many companies. E-procurement allows buyers to access new suppliers, reduce costs, and expedite order processing and delivery. This method includes strategies such as reverse auctions, online trading exchanges, and dedicated purchasing websites, each providing...
FAQs
Defined vascular pedicles preserve the blood vessels that will support later revascularization, meaning restoration of blood flow after transplantation. Surgical planning therefore must maintain these connections while separating facial tissues. Preserving the pedicles is central to maintaining graft viability and creating the anatomical basis for successful integration with the recipient’s circulation.
Facial allografts may include skin, soft tissue, bone, nerves, and blood vessels, so procurement requires coordinated anatomical separation rather than removal of a single tissue type. Each component contributes to reconstruction, while the combined graft can support restoration of appearance, speech, swallowing, and facial movement when appropriately planned.
After recovery, the graft is flushed, cooled, and transported under controlled preservation conditions. Flushing prepares the vascular structures, cooling helps maintain the tissues during handling, and controlled transport limits unnecessary variation before transplantation. These preservation steps connect the surgical recovery procedure with the logistical requirements of vascularized composite allotransplantation.
The process begins with donor consent and medical screening. Surgeons then separate the planned facial tissues while preserving the defined vascular pedicles and relevant anatomical structures. After recovery, the graft is flushed and cooled before transport under controlled preservation conditions. This sequence coordinates ethical authorization, donor assessment, surgical precision, and transplant logistics.
Precise anatomical planning helps determine how skin, soft tissue, bone, nerves, and blood vessels are separated and preserved. It also supports alignment with the recipient’s reconstructive needs. Careful planning can therefore contribute not only to restoration of facial appearance, but also to functions such as speech, swallowing, and facial movement.
This procedure is relevant when transplantation is being considered for severe facial disfigurement or functional loss. It links reconstructive surgery with organ donation, immunology, and transplant logistics, placing the operation within vascularized composite allotransplantation. Its medical importance extends beyond tissue recovery because the graft must remain viable and anatomically suitable for reconstruction.
