Cosmetic Surgery is a Branch of Plastic Surgery Plastic surgeons repair congenital

malformations (e.g., cleft lip and palate), disfiguring wounds, animal bites, burn injuries, and perform reconstructions after surgeries for chronic and/or malignant conditions

Cosmetic surgery is largely elective and designed to augment “normal” appearance

Cosmetic Surgery:Other Procedures Face lift Chemical peel Forehead lift Upper arm lift Buttock lift Thigh lift Liposuction

Motivations for Cosmetic Surgery External: avoidance of ethnic prejudice; fear of

age discrimination; coercion by spouse/parent/boss

Internal: desire to diminish unpleasant feelings like depression, shame, or social anxiety; to alter a specific feature they dislike; desire for a more youthful, healthy look that signals fertility (women); interest in developing a strong, powerful look that may facilitate career advancement

Rhinoplasty One of the most

common cosmetic surgery procedures

Reduce or increase nose size, change shape of tip or bridge, nostril size, angle between nose and lip, or correct breathing problems

Cost: $5,700 “Modern Rhinoplasty Techniques and Facial Plastic Surgery” <http://ent.pote.hu/course12.htm> 22 March 2006.

RHINOPLASTY Reduce size, remove bump(s), shorten, tilt Procedure done inside = no scars Bones may be altered 90% growth 13/14 girls, 15/16 boys Chin often done at same time $ 6,000.00 Canadian (Van Sun)

RHINOPLASTY (con’t)

BEFORE AFTER

The Asian nose is naturally wide. Just how wide the nose should be is a personal choice. Notice how the nose was narrowed to fit her face.

The bones, cartilage, and nostrils widths were reduced.

Facial Implants Used to improve facial

contours Implants made from different

materials including silicone Implant inserted into small

incision; often performed in conjunction with other facial surgery, i.e. face lift

Incision taped to reduce swelling and discomfort

Cost: $3,000-$5,000

Blepharoplasty and The Brow Lift Blepharoplasty: the removal

of fat, excess skin and muscle from upper and lower eyelids

Does not remove “crow’s feet”, wrinkles or dark circles

Brow/Forehead Lift: corrects drooping brows and smoothes forehead

Cost: $5,000

Plastic Surgery and Recovery Scars may be pink for up to six months

after surgery Risk of post-operative infections and blood

clots Fluid loss Nerve damage

Microdermabrasion Sandblaster-like device

used to spray high pressure stream of aluminum oxide or salt crystals across face and suction used to remove dead outer layer of skin.

Stimulates skin cell and collagen production.

“Microdermabrasion” Skinet. <http://www.lasercare-clinics.co.uk/Treatments/Display.asp?ID=17> 22 March 2006.

Microdermabrasion Affects only outer layer of skin Used to reduce fine lines, “crow’s feet”,

age spots, acne scars Effective for all skin types “Lunch hour procedure” Multiple treatments required for visible

results 5 to 12 treatments 2 to 3 weeks apart

Microdermabrasion Few complications

Treatment extends only to outermost layer of skin and so scarring is unlikely and recovery is rapid.

Use of eye protection during procedure prevents ocular complications such as redness, sensitivity to light, and crystals adhering to the cornea typical of early microdermabrasion treatments.

Chemical Peel Uses a solution of

phenol (deep peel), trichloroacetic acid (medium depth peel) and alphahydroxy acids (light peel) to remove damaged outer layers of skin Wrinkles, blemishes,

uneven pigmentation or sun damage

“Chemical Peels” BGPMA Department of Aesthetic Medicine <http://www.bgpma.com/html/aesthetics/peels_main.htm> 22 March 2006.

Chemical Peel Side Effects

Temporary throbbing, tingling, swelling, redness, sensitivity to sun, whiteheads

With Phenol peel: permanent lightening of skin and loss of ability to tan

Risks Infection, scarring, flare-up of skin allergies, fever

blisters, cold sores In rare cases, heart irregularities with phenol peel New wrinkles may form as skin ages

Collagen Injections Plump creased, furrowed or

sunken facial skin Add fullness to lips and backs of

hands Risks and Side effects:

Stinging, throbbing, burning sensation, redness, swelling, excess fullness, allergic reaction, rash, hives, flu-like symptoms, infection, connective tissue or autoimmune diseases

Botox Botulinum toxin is a product of the bacteria Clostridium

Botulinum Wrinkles caused when a muscle tightens. Botox is injected through the skin into the muscle and keeps the

muscle from tightening; when the muscle can't tighten, the wrinkle is less prominent

Effective for about 4 months, after which wrinkles may reappear

Botox Side effects

Droopy eyelids, flu-like symptoms, headache, upset stomach, risk of botulism (a potentially fatal disease which often results in difficulty moving the arms and legs and difficulty breathing – risk is low if Botox is used properly)

Cosmetic Dentistry Whiten teeth Correct gum line Seal gaps Fix chips or cracks Correct rotations Replace worn down or discolored teeth

Cosmetic Dentistry blends function with beauty by combining

tooth reconstruction and plastic surgery procedures on the mouth tissues (gums, jawbones, facial muscles, lips, and skin) to result in a better-looking smile

Before After

Cosmetic Dentistry Crowns: artificial coverings for teeth made

from ceramic/porcelain metal composite, gold, or a tin/aluminum mixture

Veneers: similar to crowns except they cover the forward part of the tooth only and are used exclusively for aesthetic purposes

Beauty and Morality Certain images or ideas may be considered

inherently immoral and hence do not create a valid aesthetic experience Sexual content? Politically motivated? (That which does not

encourage adherence to dictates of the state)

Religious/Philosophical Views What does it mean to worship your body or

to view your body as a temple? Taking care of your body, doing what is best

for it Treating your body with respect, compassion

and care Not the same as being obsessed with

appearance

Cultural Considerations What is acceptable fashion/use of

cosmetics in one culture may be inappropriate or offensive to another Implications for a multicultural society?

Botox Many cases of botched Botox

Four cases of botulism poisoning occurred at a Fort Lauderdale Clinic and then expanded to California. Doctors received their materials form a biological

laboratory that supplied the botulinum toxin. How can doctors know for sure that what they are

providing to their patient does not harm them?

Plastic Surgery Medical evidence shows no correlation

between cancer and breast implants Should we be concerned about long term

health risks that we are not aware of for other procedures?

INTRODUCTION Elective surgery To improve appearance the pursuit of beauty

Vanity Severe defects

Most common: face (nose, chin, ears), breasts, fat reduction (liposuction)

For youth: nose, chin, ears, breasts Not without risks Careful research

OTOPLASTY Protruding or overlarge ears Build up or replace Pre-school children More common in males $4,000.00 Canadian (Van Sun)

FACIAL PROCEDURES Botox

Botulinum toxin injected into muscles to paralyze them 4 - 12 months $375 US

Chemical Peel liquid mixture of alpha-hydroxy acids exfoliates and unclog pores $600 US per treatment

FACIAL PROCEDURES (con’t) Photofacial

intense pulsed light repairs sun damage reduces redness, dark spots no harm to skin

Captique Injections for lips soft tissue filler gives fuller plumper appearance lasts 6 mos.

LIPOSUCTION Vacuum out fat: hips, buttocks, knees, upper arms, chin,

cheeks, neck, etc. Most common areas:

Females outer thighs/abdomen Males flank/love handles

Serious procedure, painful recovery Serious complications #1 Canadian procedure – men & women (Van Sun) $3,000.00 - $9,000.00+ Canadian (Van Sun) Appropriate for youth only very select cases

THE RISKS As with any surgery

Infection Bleeding or blood clots Reaction to anesthesia Scarring

Disfigurement, paralysis, death Carefully choose surgeon

Anatomy of Facial nerve1) Intracranial part Supranuclear segment Nuclear segment Infranuclear segment

Cerebellopontine angle Internal acoustic canal Labyrinthine segment Tympanic segment Mastoid segment

2) Extracranial part

Classifications of facial nerve injury

Seddon classification of nerve injury

Neuropraxia Axonotmesis Neurotmesis

Extracranial 1. Traumatic

Facial lacerations Blunt forces Penetrating wounds Mandible fractures Iatrogenic injuries Newborn paralysis

Extracranial 2. Neoplasm

Parotid tumors Tumors of the external and middle ear Facial nerve neurinomas Metastatic lesions

3. Congenital absence of facial musculature

Evaluation of Facial paralysis Clinical feature

Central VS Peripheral facial paralysis Complete head and neck examination Cranial nerve evaluation

Electrodiagnostic testing

Topographic diagnosis

Central facial paralysis Upper motor neurone lesion Movements of the frontal and upper

orbicularis oculi tend to be spared Because of uncrossed contributions from

ipsilateral supranuclear areas Involvement of tongue Involvement of lacrimation and salivation

Peripheral paralysis Lower motor neurone lesion At rest :

less prominent wrinkles on forehead of affected side, eyebrow drop, flattened nasolabial fold, corner of mouth turned down

Unable to : wrinkle forehead, raise eyebrow, wrinkle

nasolabial fold, purse lips, show teeth, or completely close eye

Management Extracranial

etiology Trauma Iatrogenic Neoplasm

Intratemporal etiology Fracture Iatrogenic Neoplasm Idiopathic (Bell’s

palsy) Infection

Idiopathic facial palsy (Bell's Palsy)

Most common cause of facial paralysis (>50% of case)

Most age 25-30 yrs. Male : Female = 1 : 1 Left side : Right side = 1 : 1 Unilateral > bilateral Increase risk in

pregnancy 3.3 times DM 4.5 times

Recurrent rate 10% 60% have previous URI

Etiology Unknown Microcirculatory failure of vasa

nervorum Viral infection (HSV) Ischemic neuropathy Autoimmune reaction

Entrapment theory

Diagnosis By exclusion Criteria :

Paralysis or paresis of all muscle groups of one side of the face

Sudden onset Absence of signs of CNS disease Absence of signs of ear or CPA disease

Medical treatment

Corticosteroids : prednisolone 1 mg/kg/day 7-10 days

Corticosteroids combine with antiviral drug is better

Acyclovir 400 mg 5 times/day Famciclovir and valacyclovir 500 mg

bid

Surgical treatment Facial nerve decompression Indication

Completely paralysis ENOG less than 10% in 2 weeks

Appropriate time for surgery is 2-3 weeks after paralysis

Herpes Zoster Oticus (Ramsay Hunt Syndrome) 3rd most common of peripheral facial paralysis

(10%) Aged > 60 yrs. or low immune (low CMIR) Virus travels to the dorsal root extramedullary

cranial nerve ganglion Infected of HZV at auricular, external canal or

face Prodromal symptoms very similar to those

seen in Bell's palsy but usually more severe

Herpes Zoster Oticus (Ramsay Hunt Syndrome) Symptoms include severe otalgia, facial

paralysis, facial numbness, and a vesicular eruption on the concha, external auditory canal, and palate

Facial paralysis + hearing loss + vertigo “canal paralysis”

Pathophysiology & treatment liked in Bell ’s palsy

Temporal bone fractures Longitudinal fracture Transverse fracture Mixed fracture

Temporal bone fractures Signs bleeding from the external canal hemotympanum step-deformity of the osseous canal conductive hearing loss (longitudinal fracture) sensorineural hearing loss (transverse

fracture) CSF otorrhea facial nerve involvement (20% of longitudinal

fractures and 50% of transverse fractures)

Treatment Surgery is treatment of choice Indications for facial nerve exploration

incomplete paralysis iatrogenic paralysis

Contraindications : any case have no poor prognostic factors

Complications Complications of facial nerve decompre
