INTERRUPTED HORIZONTAL MATTRESS SUTURE
In interrupted horizontal mattress suture technique, the needle is inserted 2-10 mm away from the wound edge and knotted by passing back from few mm away laterally in the opposite direction. In this technique, horizontal placement of the suture provides compression of the dermal vessels and weakening of the blood flow. It allows the dead space to be closed and eversion. This technique is useful in situations where bleeding has to be stopped because it retains its tissue support and tensile strength in medium or high-tension tissue during the tissue healing process. Moreover, it is also suitable for elderly patients or patients undergoing chronic steroid treatment, as it is also convenient to hold sensitive skin tissues together.
- Used for approximation of tissue temporarily.
- In cases where suture remain in tissue for more than 7 days, permanent scars may occur.
- Risk of strangulation and necrosis may occur if the suture is overtightened.
Advantage: It is useful in high tensile areas as it meets the need for high tensile strength.
Disadvantage: May cause tissue ischemia
Uses: It is widely used in the closure of pressure zones, sometimes in flat tendon or minimal connective tissue muscles.
