Q

How can an early vs organizing hematoma present clinically?

A

Early (first 48 hrs): Fluctuant

Organizing (≥1 week post-op), thick, fibrous, adherent to adjacent tissue

Q

What is the management of early hematoma?

Q

What is the management of organized hematomas?

A

Cannot be aspirated except @ two weeks postop these undergo liquefaction and can sometimes be aspirated (or left to absorb over months)

Bromelain can also be used to help expedite hematoma resolution

19
Q

What can be given to help expedite the breakdown of a hematoma?

A

Bromelain (Ananase/Traumanase): oral concentrate of proteolytic enzymes

20
Q

What is the first clinical sign of ischemia?

A

Pallor

21
Q

What is the difference in flap survival between arterial insufficiency and venous congestion?

A

Arterial insufficiency: flaps remain viable for 12-14 hrs

Venous congestion: Flaps undergo rapid necrosis (<3-4 hrs)

22
Q

What are the clinical signs of arterial insufficiency?

A

Decreased skin temperature, lack of bleeding following pinprick test

23
Q

What are the clinical signs of venous congestion?

A

Cyanotic-purple skin color, increased dark purple bleeding after pinprick test

24
Q

What things can cause ischemia/necrosis after surgery?

A

Hematoma, infection, high wound tension

25
Q

What are some patient-related risk factors for ischemia/necrosis?

A

Smoking, nicotine-containing products

26
Q

What procedure-related risk factors exist for ischemia/necrosis?

A

To much undermining (especially too superficial), postoperative edema, sutures tied too tightly, and insufficient or excessive electrocoagulation

27
Q

Should necrotic tissue be debrided?

A

NO! Unless there are signs of infection (serves as a biologic dressing)

28
Q

How can ischemia/necrosis risk be minimized?

A

Suture replacement to decrease tension, the elevation of the surgical area (decrease edema), heat application (increased circulation), hyperbaric oxygen

29
Q

When is a wound at the highest risk of dehiscence?

A

Time of suture removal

(can remove sutures in stages if more support is needed)

30
Q

What is the treatment for dehiscence?

A

Classic teaching/boards: Resuture if <24 hrs after surgery, if >24 hrs then secondary intention healing

Newer studies suggest that if there is no infxn, hematoma, necrosis then resuturing can be done

31
Q

If surgery is performed on the ear and significant pain is noted after surgery what is this? and how is it treated?

A

Chondritis, very painful, can occur on any ear procedure involving cartilage. Can be associated with pseudomonas

Tx w/ NSAIDs for pain, quinolone if suspected infection

32
Q

What is a risk factor test for ectropion that can be done?

A

The “snap test” (lower eyelid is pulled down, this should snap back normally, but if it takes a while (or doesn’t) go back to being against the eye this is a risk factor). Medial and lateral canthus test as well (these are pulled, there should not be much laxity here, more is abnormal)

if these are abnormal, higher risk

33
Q

What degree of eyebrow lift is ok for the closure of surgical wounds?

A

≤3mm is ok, > 3mm should be avoided (wont self resolve)

34
Q

What surgical sites are most common for keloids?

A

Anterior neck, chest, and scars crossing jawline

35
Q

What are some risk factors for trapdoor/pincushioning defects?

A

Often from concentric forces, so curved incision lines like bilobed flaps, nasolabial fold transposition flaps

36
Q

How can pincushioning/trapdoor defects be avoided?

A

Wide undermining, sizing the flap properly, and good flap adherence to the wound base

37
Q

What sutures have the highest risk of spitting?

A

Vicryl sutures placed superficially

38
Q

When do spitting sutures usually occur and how can they be addressed?

A

1-3 months postop, can be removed if possible

39
Q

How can ectropion be prevented when working near the lower eyelid?

A

Periosteal tacking sutures, Frost suspension sutures (a stitch is thrown in the lower eyelid, near the medial canthus, and attached to the skin of the upper eyelid suspending/holding the lower eyelid up)

40
Q

What is the highest risk suture for suture granuloma?

A

Vicryl (polyglactin-910)

41
Q

When do suture granulomas generally occur postop and what should be done?

A

1-3 months, resolves itself but can use intralesional triamcinolone to help things along

42
Q

How are post-surgical telangiectasias treated?

A

Pulsed dye laser

43
Q

How can thickened scars be treated?

A

Massage or intralesional steroid

44
Q

What can be done to treat webbed or contracted scars?

A

Z-plasty revision

45
Q

How can motor nerve damage be avoided when operating on the face?

A

Staying above the SMAS

46
Q

What can be done to minimize abnormal sensation issues after surgery on the forehead?

A

Orienting excisions vertically rather than horizontally if possible, can decrease the number of sensory nerve branches transected
