Q

Nose

A

Subunits (dorsum,sidewall,tip,ala, soft triangle,columella)
Layers (mucosa,cartilage,skin)

**2 stages: 1st is FRF with extra fascia extension, fascia is lining. 2nd stage rib cartilage is used as cantilever dorsal nasal graft and BL conchal alar batten grafts for alar support, then fold flap (with skin paddle over cartilage. 2nd stage remove majority of skin paddle but leave lining and add cartilage and cover with forehead flap.

Q

Eyelid ptosis

A

Acquired - 2/2 disinsertion of levator aponeurosis
Congenital - nonfunctional levator

PE: Bells, EOM, Herrings law (cover that eye up)

**wake them up, 4:1 correction to ptosis (ie 2mm ptosis is 8mm correction)

Mild: 2mm droop, 10-15mm excursion - FS
clamp conjunctiva at superior edge of tarsus with mueller muscle, suture with runnnig chromic then resect tissue. excise 8mm tissue.

Mod: 3mm droop, 5-10mm excursion- LA transcutaneous, suture levator aponeurosis back into tarsus

Severe: 4mm droop, 5mm excursion -FA
use synthetic or TFL graft to thread thru anterior lamella then subQ up to above brow, knot and tied to subQ tissue.

Comp:
Cheimosis: tobradex, patch, tape

Q

Mandible fx

A

Complications:
infection: washout and keep HW if early, remove and ex fix / bone graft later if late
malocclusion: guiding elastics vs revise later
malunion: revise
nonuion: revise with bone graft
plate exposure: remove plate
nerve injury: marge, watchful waiting unless certain you injured it

Condylar head: Dislocation out of glenoid fossa, foreign body, BL condylar

Q

Cleft lip

A

https://journals.lww.com/plasreconsurg/pages/video.aspx?v=157&autoPlay=false

Hx: Feeding and breathing issues

Counsel: palate at 1 year

NAM immediately

Fisher anatomic subunit repair

Comp:

17
Q

Nerve Lac

A

Radial N –> TT (PT - ECRB, FCR - EDC, PL - EIP)
N growth: 1mm/day or 1 inch/mo
EMG: takes 1 month to show injury

18
Q

Tendon Transfer

A

RN: Brand
MN: pinch (BR –> FPL)
IP flexion (FDP 4/5 –> 2/3)
opposition (FDS 4 –> APB)

UN:

How to tension: 50/50 → tight as you can, then no tension and do middle between those. Confirm with tenodesis.

Postop: splint 4 weeks, AROM after

19
Q

Sagital band injury

A

partial just treat with relative motion extension splint
Complete → repair or use PL graft tendon loop thru MC head

20
Q

Boutenierre
Swan Neck

A

2 difficult ones:
Boutenneire → chronic central slip
** is this passively correctable. If no → OT, if yes → surgery
Lateral band centralization, take medial half LB and centralize it and anchor to p2
Swan neck → Chronic terminal tendon injury
** is this passively correctable. If no → OT, if yes → surgery
FDS tenodesis → 1 slip FDS into P2 in slight flexion
**Bunnell intrinsic tightness test, if present do release over P1, excise triangle of extensor hood

21
Q

Meningocele

A
  • recommend VP shunt, neurosurgery (reduce, repair dura), operate within 1d
  • Tx;
    1) rhomboid flap going vertically up back OR ying yang flaps
    2) primary closure with lateral relaxing incisions
    3) SGAP flap (lateral edge of sacrum (medially), iliac crest (superior), ischial protuberance (inferior) — perfs 2/3 way from greater troch –> PSIS)
    4) paraspinal advancement and STSG
    5) LD release origin and insertion and slide whole muscle down
22
Q

Lymphedema

A

Dx: lymphoscintigraphy via ICG

Tx:
Conservative → complete decongestive therapy via lymphedema therapist (massage, compression dressings, skin care)

Surgical:
-Charles procedure → circumferential subfascial excision with STSG after (modified charles is where you VAC it after then STSG 1 week later)
-Vascularized LN transfer:
Donor options: supraclavicular (transverse cervical vessels), **superficial inguinal nodes (superficial circumflex vessels → can take skin paddle which is essentially a SCIP flap)
Lymphovenous anastomosis : superficial lymphatics and superficial veins.

23
Q

AV malformation / Hemangioma

A
24
Q

Facial Palsy

A

** upper eyelid closure, lower lid laxity, smile

upper lid - gold weight, pre tarsal

Smile:

25
Q

Tuberous Breast

A

Stage: TE first, 2nd stage 3 mo later - subfascial implant with PA lift

Complication:
Double bubble –> release bands at IMF, ensure no bottoming out, fat graft

26
Q

Perineal wound

A

VRAM -
Gracilis musculocutaneous - MFCA
Singapore - internal pudendal off of internal iliac

27
Q

Chest wall wound

A

<4 ribs or <5cm - dont need rigid fixation

ADM lining + rib plating + flap OR
PTFE goretex mesh + flap

Flaps:
pedicled:
LD, VRAM/TRAM pec, serratus** ( Lat thoraciac and thoracodorsal), omentum**
