The ideal suture for delicate surgery in small exotic animals should have excellent knot‐holding capability and ease of handling, and should elicit a minimal inflammatory reaction (Phillips and Aronson 2012). Microsuture is swaged onto a 1/2 or 3/8 circle needle with a round taper‐point or micropoint spatula‐shaped needle tip. Surgical Specialties Corporation (Wyomissing, PA) uses specialized needle geometry in the manufacture of Sharppoint™ microsutures to flatten the middle ⅓ of the needle for secure grasping while maintaining a pointed microsurgical needle tip.

Sizes of suture for microsurgical procedures range from 4‐0 to 11‐0, progressing from less to more delicate work. Although monofilament sutures such as nylon, polypropylene, or polydioxanone are preferred for strength, durability, and inciting minimal inflammation, multifilament sutures have excellent knot‐holding ability. When passed though bone wax, braided multifilament sutures have improved handling and less drag through tissues. Multifilament sutures should be used with caution in infected tissues as the braided configuration may provide a nidus for bacterial growth and proliferation (Phillips and Aronson 2012).
