Transcript of "Facial Plastic and Reconstructive Surgery Inservice Review"

  1. 1. Facial Plastic and Reconstructive Surgery Inservice Review 2008
  2. 2. Select Topics <ul><li>Blepharoplasty </li></ul><ul><li>Aging Face / Rhytidectomy </li></ul><ul><li>Rhinoplasty </li></ul><ul><li>Facial Resurfacing </li></ul><ul><li>Cleft Lip/Palate </li></ul><ul><li>Hair Transplantation </li></ul>
  3. 3. Blepharoplasty <ul><li>Dermatochalasis : laxity and redundancy of eyelid skin secondary to aging. (OLDER PATIENTS). </li></ul><ul><li>Blepharochalasis : rare familial condition, young women with recurrent eyelid edema (bouts of localized angioedema, idiopathic) with skin and soft tissue laxity… levator damage and ptosis… </li></ul>
  4. 4. Blepharoplasty: Patient Eval <ul><li>Dry eyes: Schirmer’s test (placement of filter paper in the lateral fornix for 5 min. >15mm normal, 10-15 mm borderline, < 10 mm inadequate. Not an absolute contraindication (more conservative excision). </li></ul><ul><li>Snap Test (lower lid): inferior pull and release. Slow return or no return without blinking, high risk for ectropion, consider canthal tightening. </li></ul><ul><li>Distraction Test (lower lid): lid is grasped between the thumb and forefinger and pulled anteriorly (>10mm -> lax). </li></ul>
  5. 5. Blepharoplasty <ul><li>Upper: skin pinch to measure redundancy, skin / muscle / fat excision. </li></ul><ul><li>Lower: Subciliary (skin muscle flap) vs Trans-Conjunctival… Extensive dermatochalasis / orbicularis hypertrophy… Scleral show (“round eye” deformity) and ectropion with subciliary… </li></ul>
  6. 6. Blepharoplasty - Complications <ul><li>Bleeding: pain, proptosis, vision changes (severe cases). Tx: emergent canthotomy and cantholysis, return to the O.R., ophtho consult (mannitol, steroids, acetazolomide). </li></ul><ul><li>Extra-ocular muscle injury: most common inferior oblique (btw medial and central fat pads) </li></ul><ul><li>Ptosis: transection of weakening of aponeurosis </li></ul><ul><li>Lower eyelid position: ectropion / entropion </li></ul><ul><li>Dry eye syndrome: most common functional problem, exacerbated by lagophthalmos (inability to close eyes) and/or lower eyelid retraction. </li></ul>
  7. 7. Question #1 <ul><li>Photo of a trans-conjunctival approach to lower bleph. Patient has pain in the eye with irritation post-op. Next step: </li></ul><ul><ul><li>Observation </li></ul></ul><ul><ul><li>Fluorescein dye test </li></ul></ul><ul><ul><li>Lateral cantholysis </li></ul></ul><ul><ul><li>OR for exploration </li></ul></ul>Fluorescein Dye Test: to r/o corneal abrasion / gtts… Extreme pain/proptosis->hematoma->cantholysis / OR exploration
  8. 8. Question #2 <ul><li>S/P blepharoplasty, pt develops ptosis in one eye. What is the cause? </li></ul>Levator muscle or aponeurosis injury: clinical feature: high lid crease. Diagnosis: hold the lid down and ask the patient to look up. Treatment? Exploration : the detached distal margin of the levator should be identified and re-attached to the tarsus
  9. 9. Question #3 <ul><li>Explain the absence of lid crease in the Asian eye-lid… </li></ul>Levator muscle (aponeurosis)_has no connection to pretarsal skin!
  10. 10. Aging Face / Rhytidectomy
  11. 11. Anatomy - Glabella <ul><li>Procerus (vertical muscle): horizontal lines </li></ul><ul><li>Corrugator (oblique / horizontal muscle): vertical lines </li></ul>
  12. 12. Anatomy - Temple
  13. 13. Complications: Nerve Injuries <ul><li>Most common nerve injury: greater auricular (1-7%) </li></ul><ul><li>Most common motor (VII) nerve injury: Temporal > Marginal (2-5%), most commonly neuropraxia secondary to traction and/or cautery </li></ul>
  14. 14. Complications <ul><li>Most common complication: hematoma (1-10%), greater in men… Pain (remove the dressing to r/o hematoma). </li></ul><ul><li>Treatment: aspiration vs evacuation in the O.R. Key: prompt intervention is indicated to prevent skin flap necrosis. </li></ul><ul><li>Skin necrosis: due to excessive tension on the skin flap, higher incidence in smokers, hematomas. </li></ul>
  15. 15. Complications <ul><li>Scar hypertrophy: Kenalog injections </li></ul><ul><li>Earlobe traction inferiorly (pixie or satyr ear): V-Y repair </li></ul><ul><li>Incisional hair loss: if permanent, consider micrografting </li></ul>
  16. 16. Question #1 <ul><li>Drawing of an axon at the neuromuscular junction. Where does Botox A work? </li></ul><ul><ul><li>Axon </li></ul></ul><ul><ul><li>Pre-Synaptic </li></ul></ul><ul><ul><li>Cleft </li></ul></ul><ul><ul><li>Post-Synaptic </li></ul></ul><ul><ul><li>Beyond </li></ul></ul>Pre-Synaptic : Prevents release of vesicles containing acetylcholine.
  17. 17. Question #2 <ul><li>Temporal rhytidectomy scar with a bald patch behind it. Cause: </li></ul><ul><ul><li>Poor incision placement </li></ul></ul><ul><ul><li>Inadequate SMAS plication </li></ul></ul><ul><ul><li>Injury to hair follicles during incision </li></ul></ul>Hair Follicle Injury : improper beveling of the incision!
  18. 18. Question #3 <ul><li>Most common site for skin sloughing s/p rhytidectomy: </li></ul><ul><ul><li>Temporal </li></ul></ul><ul><ul><li>Pre-Auricular </li></ul></ul><ul><ul><li>Post-Auricular </li></ul></ul><ul><ul><li>Posterior Scalp </li></ul></ul>Post-auricular : distal-most portion of the face-lift flap!
  19. 19. Rhinoplasty <ul><li>Tip Support Mechanisms </li></ul><ul><ul><li>MAJOR: size/shape/resilience of lower lats, medial crural attachment to caudal septal cartilage, attachment of upper lats (caudal border) to lower lats (cephalic border) </li></ul></ul><ul><ul><li>MINOR: interdomal ligament, sesamoid complex, cartilage attachment to the overlying skin/muscle, membranous septum, etc </li></ul></ul>
  20. 20. Internal Nasal Valve <ul><li>Nasal septum, caudal margin of the upper lateral cartilage, floor of the nose/turbinate. </li></ul><ul><li>Collapse usually seen following reduction rhinoplasty (dorsal hump reduction). </li></ul><ul><li>Correction: spreader grafts (between the septum and upper lateral cartilages) </li></ul>
  21. 21. External Nasal Valve <ul><li>Nostril, alae (fibro-fatty tissue, lateral crura of the lower lateral cartilage). </li></ul><ul><li>Commonly seen with aging (loss of support) or in facial paralysis. </li></ul><ul><li>Correction by placement of structural grafts into the alar lobule to provide support (batten grafts) </li></ul><ul><li>Batten grafts: cartilage grafts placed into a precise pocket at the point of maximal lateral wall collapse (or site of supra alar pinching) </li></ul>
  22. 22. Complications <ul><li>Rocker Deformity </li></ul><ul><li>Pollybeak </li></ul><ul><li>Inverted ‘V’ </li></ul><ul><li>Bossae </li></ul><ul><li>Alar Retraction </li></ul><ul><li>Saddle Nose </li></ul><ul><li>Nasal Valve Collapse </li></ul>
  23. 23. Facial Resurfacing
  24. 24. Chemical Peels
  25. 25. Depth of Peels <ul><li>Superficial: EPIDERMIS ONLY </li></ul><ul><ul><li>Glycolic acid, Jessner, Retin A </li></ul></ul><ul><li>Medium: PAPILLARY DERMIS </li></ul><ul><ul><li>TCA (at 20, 30, or 50%) </li></ul></ul><ul><li>Deep: RETICULAR DERMIS </li></ul><ul><ul><li>Phenol of varying concentrations. Key: higher concentration -> a less deep peel. Other: systemic toxicity, cannot be used in patients with heart conditions, etc. </li></ul></ul>
  26. 26. Question #1 <ul><li>What agent used in a face peel is cardiotoxic: </li></ul><ul><ul><li>TCA </li></ul></ul><ul><ul><li>Glycolic Acid </li></ul></ul><ul><ul><li>Phenol </li></ul></ul>Phenol : deep chemo-exfoliation, cardiac arrhythmias, cardiac monitoring (?). Other complications: scarring, epidermal inclusion cysts (milia), pigmentation changes, herpetic outbreaks (prophylactic acyclovir).
  27. 27. Cleft Lip / Palate <ul><li>General paradigm: fix the lip until 1 year, then palate. </li></ul><ul><li>Rule of 10s for the lip: >10 weeks, >10 lbs, Hgb > 10. </li></ul>
  28. 28. Cleft Lip / Palate <ul><li>3 months: cleft lip, rip rhinoplasty, MTs </li></ul><ul><li>1 year: cleft palate repair </li></ul><ul><li>5 years: columellar lengthening </li></ul><ul><li>10 years: alveolar bone grafting and orthodontic work </li></ul><ul><li>15 years: plastics </li></ul>
  29. 29. Question #1 <ul><li>4 month old with cleft lip and palate. Surgery: </li></ul><ul><ul><li>Alveolar bone graft </li></ul></ul><ul><ul><li>Cleft lip repair </li></ul></ul><ul><ul><li>Cleft palate repair </li></ul></ul>Cleft Lip Repair
  30. 30. Hair Transplantation <ul><li>Current Technique: FOLLICULAR UNIT GRAFTING </li></ul><ul><li>Follicular unit: terminal hairs surrounded by an adventitial sheath, containing sebaceous glands… allows microscopic dissection permitting excision of all excess non-hair-bearing tissue… #hairs: 1-4, most commonly 2-3. </li></ul><ul><li>Technique: Micrografts (1-2 hairs) are placed along the hairline (irregular), minigrafts (3-5 hairs) for remaining areas. </li></ul>
  31. 31. Hair Transplantation <ul><li>TELOGEN EFFLUVIUM STAGE: transplanted hairs fall out in several weeks, start to regrow in 8-10 weeks... </li></ul>
  32. 32. Question #1 <ul><li>Best way to evaluate a 35 year-old man for hair transplantation: </li></ul><ul><ul><li>Wait until 45 years of age and re-evaluate </li></ul></ul><ul><ul><li>Wet hair </li></ul></ul><ul><ul><li>Assess hair loss pattern of paternal grandfather </li></ul></ul><ul><ul><li>Plan surgery based on future pattern of hair loss </li></ul></ul>Plan based on future hair loss pattern: think of class III becoming class VI…
