Vascular event
Anaphylaxis
Bleeding
Vasovagal episode
Skin changes
Factors for nodule formation
Disease that creates immune mediated response
e.g Influenza
Anterograde embolism vs retrograde
Distally to terminal arteries
vs
Moves in opposition to blood flow
Venous complications
Congestion and compartment syndrome
Where are the labial arteries most at risk
In the midline - higher risk of subctaneous arteries
Factors affecting needle aspiration (6)
Primed needle
Product viscosity
Length of time
Needle length
Steadiness of hands
Amount of negative pressure
Conservative management of VO
Firm massage for 5 mintuutes
Warm compress for vasodilaton
Firm tapping over occluded area may dislodge emboli
Skin changes with filler
Neovascularisation from trauma/tissue expansion - treat with laser if resistant
Hyperpigmentation - Fitz IV-VI
Rosacea flare
Scarring from other complication (ifection/VO)
Filler biofilm
Aggregation of microorganisms on implanted filler
formed by extracellilar matrix of polymeric fibrinogen and fibronectin
resitant to abx penetration
First line abx for infection
Flucloxacillin 500mg QDS PO
or
Clarithromycin 500mg BD PO
Malar oedema
May resolve over 2-3 weeks
Encourage lymphatic drainage and cold compress several times a day
Avoid steroids
Type IV hypersensitivity
Delayed reaction mediated by cellular response
T-lymphocites
Inflammatory nodules
DO NOT RESPOND TO ANTIHISTAMINES, can be treated with oral steroids, tapering dose
What to do if unsure of hypersensitivity vs infection
Treat with abx first
Then weaning steriod course
May need to dissolve to remove underlying trigger
Type I hypersensitivity
IgE mediated - mast cell activation - fast onset
atopy, anaphylaxis, allergy, angioedema
Responds to antihistamines
Nerve damage
rare
trauma through laceration, compression, occluding exiting foramen
Bells palsy management
Artificial tears
steroids
Eye patch
Nodule management
Firm massage if occur immediately
Aspiration if delayed
Cause of inflammatory module
Biofilm infection of filler
Management of inflammatory nodule
Two weeks of abx, up to 4 weeks
Macrolide - clari 500mg BD
Tetracycline - minocycline 100mg BD - anti inflammatory properties
Dual antibiotic therapy
add doxycycline 100mg BD or ciprofloxacin 500mg BD
If infection of filler not improving
Punch biopsy and culture
Surgical excision
Intralesional antibiotics
Hyaluronidase dissolving
Granuloma character
Red firm papules or nodules
Subdermal
Appear within 6 months of treatment
Usually non-biodegradeable products, not HA
