                                                       This book has been written primarily for medical students, with
                    Adam Lowenstein, Chair             constant attention to the thought, “Is this something a student

                        David H. Song, MD              Plastic surgery had its beginning thousands of years ago, when

                    Amir H. Dorafshar, MBChB           has thrust the plastic surgeon of today into the forefront of advances
                                                       in small vessel and nerve repair, culminating in the successful

     large urban settings. However, there is an increasing need for more
     plastic surgeons in the smaller communities and rural areas of this
     country — many metropolitan areas with populations of 65,000 to
     268,000 have no plastic surgeons, leaving a large number of areas
     needing plastic surgery expertise. There are approximately 6,000
     board certified plastic surgeons in the United States; many of those
     currently certified by The American Board of Plastic Surgery
     received certification in the past ten years. Despite this recent rapid
     growth, there are opportunities for plastic surgeons in community
     and academic practice.
     Plastic surgery is an old specialty with references that date back
     thousands of years. It has survived and flourished because it is a
     changing specialty built by imaginative, creative and innovative
     surgeons with a broad background and education.
     The limit of the specialty is bound only by the imagination and
     expertise of those in its practice. The opportunities for the future
     are open to those who wish to be challenged.

CHAPTER 1
WOUNDS
A wound can be defined as a disruption of the normal anatomical
relationships of tissues as a result of injury. The injury may be
intentional such as a surgical incision or accidental following
trauma. Immediately following wounding, the healing process
begins.
I.   STAGES OR PHASES OF WOUND HEALING
     Regardless of type of wound healing, stages or phases are the
     same except that the time required for each stage depends on
     the type of healing.
     A. Substrate phase (inflammatory, lag or exudative stage or
          phase — days 1-4)
          1. Symptoms and signs of inflammation
              a. Redness (rubor), heat (calor), swelling (tumor),
                   pain (tumor), and loss of function
          2. Physiology of inflammation
              a. Leukocyte margination, sticking, emigration
                   through vessel walls
              b. Venule dilation and lymphatic blockade
              c. Neutrophil chemotaxis and phagocytosis
          3. Removal of clot, debris, bacteria, and other
              impediments of wound healing
          4. Lasts finite length of time (approximately four days)
              in primary intention healing
          5. Continues until wound is closed (unspecified time) in
              secondary and tertiary intention healing
     B. Proliferative phase (collagen and fibroblastic stage or
          phase — approximately days 4-42)
          1. Synthesis of collagen tissue from fibroblasts
          2. Increased rate of collagen synthesis for 42-60 days
          3. Rapid gain of tensile strength in the wound (Fig. 1-1)
     C. Remodeling phase (maturation stage or phase — from
          approximately three weeks onward)
          1. Maturation by intermolecular cross-linking of collagen
              leads to flattening of scar
          2. Requires approximately 9 months in an adult —
              longer in children
          3. Dynamic, ongoing

                                                                      1
                                                                                          4.   Although contraction (the process of contracting) is
                                                                                               normal in wound healing, one must beware of
                                                                                               contracture (an end result — may be caused by
                                                                                               contraction of scar and is a pathological deformity)
                                                                                          5. Secondary healing beneficial in some wounds,
                                                                                               e.g. perineum, heavily contaminated wounds, scalp
                                                                                     C.   Tertiary healing (by tertiary intention) — delayed wound
                                                                                          closure after several days
                                                                                          1. Distinguishing feature of this type of healing is the
                                                                                               intentional interruption of healing begun as
                                                                                               secondary intention
                                                                                          2. Can occur any time after granulation tissue has
                                                                                               formed in wound
                                                                                          3. Delayed closure should be performed when wound is
                                                                                               not infected (usually 105 or fewer bacteria/gram of

          A. Primary healing (by primary intention) — wound closure                 A. Local factors most important because we can control
             by direct approximation, pedicle flap or skin graft                       them
             1. Debridement and irrigation minimize inflammation                       1. Tissue trauma — must be kept at a minimum
             2. Dermis should be accurately approximated with                          2. Hematoma — associated with higher infection rate

             aesthetically acceptable                                        such as oral and nasal mucosa
    C.   Types of wounds and their treatment                             5. Use anatomic landmarks to advantage, e.g. alignment
         1. Abrasion — cleanse to remove foreign material                    of vermilion border, nostril sill, eyebrow, helical rim
             a. Consider scrub brush or dermabrasion to             E.   Wounds of the upper extremity (See Chapter 6)

         2. Contusion — consider need to evacuate hematoma if                     plastic bag and the bag in ice
             collection is present                                       2. Cheek injury — examine for parotid duct and/or
             a. Early — minimize by cooling with ice (24-48                  facial nerve injury
                  hours)                                                 3. Intraoral injuries — tongue, cheek, palate, and lip
             b. Later — warmth to speed absorption of blood                  wounds require suturing
         3. Laceration — trim wound edges if necessary (ragged,          4. Eyelids — align grey line and close in layers —
             contused) and suture                                            consider temporary tarrsoraphy

                         (Fig. 6-9) should be repaired by a trained hand
                         surgeon
                   b. If a hand surgeon is not available, clean and
                         suture the skin wound, splint the hand, and refer
                         as soon as possible for delayed primary repair.
                         Repair needs to be done within 10 days
               9. Reduce fractures and dislocations, apply internal or
                   external fixation if needed
               10. Postoperative dressings
                   a. Splinting should be in safe position when
                         possible, but alternative positioning may be
                         required to protect tendon or nerve repairs

                         performed distally if aesthetic deformity extends
                         into lower half of the thighs
           D.   Medial thigh lift
                1. Classic medial thigh lift plagued with problems such
                    as inferior migration and widening of the scars, lateral
                    traction deformities of the vulva, and early ptosis
                    recurrence
                2. Results improved with suspension of the superficial
                    fascial system to Colles fascia along the pubic ramus
           E.   Back
                1. Direct excision of back rolls can be achieved
                2. Incisions and excisions are separate from buttock
                    procedures
                3. Excisions may be combined with breast procedures
           F.   Buttock
                1. Excision may be superior or inferior aspect of the
                    buttock
                2. Inferior tissue excision may lead to flattening of the
                    buttock and an inferior buttock scar as opposed to
                    crease
                3. Excision may be combined with the lower body lift
