In certain cases, vacuum-sealing drainage (VSD) may help the wound heal, especially in Fournier gangrene. For necrotizing infection of the perineal area (Fournier's gangrene), wound debridement and wound care in this area can be difficult because of the excretory products that often render this area dirty and affect the wound-healing process.
The menisci are nourished by small blood vessels but have a large area in the center with no direct blood supply (avascular). This presents a problem when there is an injury to the meniscus, as the avascular areas tend not to heal. Without the essential nutrients supplied by blood vessels, healing cannot take place.

A volcanic fissure and lava channel. A fissure vent, also known as a volcanic fissure or eruption fissure, is a long volcanic vent through which lava erupts. Fissure vents are connected to deep magma reservoirs and are typically found in and along rifts and rift zones. [14] They are commonly associated with shield volcanoes.
A seventeenth fissure appears on Kilauea volcano spewing toxic gas and lava in its surrounding environment. Jayson Albano reports. Huge fissure opens on Hawaiian volcano [Video]
In cases of pre-existing or suspected fissure, use of a lubricating ointment (It is important to note that hemorrhoid ointment is contraindicated because it constricts small blood vessels, thus causes a decrease in blood flow, which prevents healing). In infants, frequent diaper change can prevent anal fissure. As constipation can be a cause ...
Timing is important to wound healing. Critically, the timing of wound re-epithelialization can decide the outcome of the healing. [11] If the epithelization of tissue over a denuded area is slow, a scar will form over many weeks, or months; [12] [13] If the epithelization of a wounded area is fast, the healing will result in regeneration.
Schematic image comparing a skin fissure to an erosion and an ulcer. The surface of the knuckles of a hand with xeroderma, showing skin cracking (generalized skin fissuring). A skin fissure is a cutaneous condition in which there is a linear-like cleavage of skin, sometimes defined as extending into the dermis. [1] It is smaller than a skin ...
Dalrymple's sign is a widened palpebral (eyelid) opening, or eyelid spasm, seen in thyrotoxicosis (as seen in Graves' disease, exophthalmic goitre and other hyperthyroid conditions), causing abnormal wideness of the palpebral fissure.
