Suturing choice depends on wound type. Simple interrupted sutures give strength and versatility, mattress sutures evert edges and spread tension, and deep dermal ones relieve surface stress. Subcuticular sutures improve appearance, while vertical mattress and secure knots prevent dehiscence.
Transposition flaps are essential in reconstructive surgery. An ideal option for redirecting tissue into adjacent defects, with superior cosmetic outcomes compared to simple rotation or advancement flaps.
Surgical instruments improve efficiency and minimize trauma. Scalpels suit different incisions, forceps may be toothed or atraumatic, retractors provide exposure, scissors vary by tissue, & electrosurgery offers cutting & coagulation. Proper selection, handling, & set preparation enhance outcomes.
A summary of the classification of sutures, common materials used in plastic surgery, the USP sizing system, needle designs, and practical guidelines for choosing and removing sutures.
Local flaps move adjacent, vascularized tissue. Classified by perfusion (random/axial/perforator), composition (cutaneous→osseomyocutaneous), and movement (advancement/rotation/transposition/interpolation). Selection hinges on defect, tension vectors, and aesthetic subunits.
The reconstructive ladder guides wound closure from simple to complex: secondary intention, primary closure, skin grafts, local flaps, pedicled flaps, & free tissue transfer. Choice is defect- and patient-specific, evidence-based, with “elevator” jumps when higher rungs optimize outcomes.
Mastopexy and breast reduction are reshaping procedures involving skin excision and NAC repositioning. Mastopexy restores shape without volume loss, while reduction also removes tissue to ease symptoms. Technique depends on ptosis grade, volume, and patient goals.
Ulnar nerve tendon transfers restore key hand functions such as grip strength, key pinch, and correct clawing after ulnar nerve palsy. By transferring muscles like the extensor carpi radialis brevis (ECRB) or flexor digitorum superficialis (FDS), tendon transfers improve hand movement and strength.
Radial nerve tendon transfers restore wrist, finger, and thumb extension when direct nerve repair isn't possible. Using tendons like Pronator Teres or Flexor Carpi Ulnaris, the procedure requires supple joints and healthy tissue. Success rates are high, with 80-90% achieving good outcomes.
The upper eyelid contains a mixture of skin, muscle, fat, tarsal plate, and conjunctiva and is divided into 3 compartments (anterior, middle, and posterior lamellae). Understanding the anatomy is fundamental for oculoplastics.
Lower-eyelid surgery demands precise knowledge of its three lamellae: skin-orbicularis anteriorly, septum with fat pads and SOOF centrally, and tarsus-conjunctiva with retractors posteriorly. Key ligaments, vessels, and lacrimal drainage define support, aging changes, and surgical risk.
