1 Pediatric Tympanoplasty
Incisions and Decisions

2 Tympanoplasty most common otologic procedure in children
focus on success rates should focus on decision making timing of surgery technique Eustachian tube health

3 Tympanoplasty pediatric tympanoplasty differs from adult:
etiology growth importance of audition surgical results are variable experiential data

4 Definitions myringoplasty tympanoplasty mastoidectomy drum middle ear

5 Tympanic Membrane Healing
normal healing epithelialization contraction growth inhibition

6 Tympanic Membrane Healing
normal healing epithelialization contraction growth inhibition

7 Tympanic Membrane Healing
normal healing epithelialization contraction growth inhibition

8 Tympanic Membrane Perforation
middle ear needs aeration ET dysfunction recurrent OM foreign body

9 Tympanic Membrane Perforation
middle ear needs aeration ET dysfunction recurrent OM foreign body

10 Tympanoplasty set-up for normal repair initiate epithelialization
diminish obstacles guide edges

11 Tympanoplasty set-up for normal repair initiate epithelialization
diminish obstacles guide edges

12 Tympanoplasty set-up for normal repair initiate epithelialization
diminish obstacles guide edges

13 Top Ten Tympanoplasty Tips
1. upper respiratory system 2. define the outcome 3. age 4. otorrhea 5. characteristics affects decisions 6. mind the jugular 7. material 8. pull-up don’t push-up 9. craniofacial anomalies 10. durability results from decisions

14 1. Upper Respiratory System
ear is a component Eustachian Tube mucosa allergy irritative environmental immunologic

15 Middle Ear Ventilation

16 Contralateral Eustachian Tube
best predictor of success generally paired system ½ Pressure ½ Pressure Pressure with swallowing

17 2. Define Outcome quality of life otorrhea hearing preservation
restoration

18 “Successful” Tympanoplasty
surgeon intact drum no morbidity patient/family ability to swim symptom resolution improved hearing keratin growing from umbo into Right Ear Perforation, 8 year old boy

19 Morbidity taste disturbance ear sticks out noticeable scar pain
allergic reaction hearing loss facial palsy

20 Morbidity

21 Relative Contraindications
asymptomatic perforation unfit for surgery repeated failures unfavorable conditions unstable contralateral ear cleft palate(?) smoking 13year old, stable dry perforation, ++++ anxiety about operations

22 3. Age age is the only factor which affects rate of success in children

23 3. Age 4 year old, no OME burned by arc welding spark age is the only factor which affects rate of success in children no it’s not! 11year old, CLP, bilateral CSOM, failed repair

24 3. Age age is the only factor which affects rate of success in children no it’s not! percentage of success 5 10 15 20

25 3. Age age is the only factor which affects rate of success in children no it’s not! yes it is!!

26 3. Age age is the only factor which affects rate of success in children no it’s not! yes it is!!

27 4. Otorrhea is the otorrhea causing the perforation?
11year old, CLP, bilateral CSOM, failed repair is the otorrhea causing the perforation? is the perforation causing the otorrhea?

28 Middle Ear Physiology? Temperature 38oC Temperature 5oC Humidity 85%
30%

29 Middle Ear Physiology? Temperature 21oC Temperature 19oC Humidity 49%
47%

30 5. Characteristics of the Perforation
size, position, revision and tympanosclerosis don’t impact success impact selection of: technique material timing of OR

31 Characteristics difficult characteristics revision
total/subtotal TM perforation anterior marginal perforations tympanosclerosis

32 Lateral Graft Tympanoplasty with Alloderm

33 Lateral Graft Tympanoplasty
equal closure rate “better” closure of air/bone gap

34 6. Mind the Jugular Vein elevating the annulus right > left

35 Mind the Jugular Vein elevating the annulus right > left

36 Mind the Jugular Vein elevating the annulus right > left

37 7. Choosing Materials temporalis fascia tragal perichondrium
tragal cartilage allografts Alloderm (human dermis) Surgysis (porcine sub-mucosa) anterior inferior

38 7. Choosing Materials temporalis fascia tragal perichondrium*
tragal cartilage* allografts Alloderm (human dermis) Surgysis (porcine sub-mucosa) anterior inferior

39 Butterfly Graft Tympanoplasty
case selection: <1/3 of drum minimal contact with malleus advantages fast efficacious

40 Forming the Graft tragal cartilage one side with perichondrium
form it into the shape of a ventilation tube

41 Forming the Graft tragal cartilage one side with perichondrium
form it into the shape of a ventilation tube

42 Forming the Graft tragal cartilage one side with perichondrium
form it into the shape of a ventilation tube

43 Butterfly Graft Tympanoplasty
great technique to have in your arsenal

44 8. Pull-Up Don’t Push Down
gelfoam causes middle ear fibrosis reduced aeration? prefer to suspend graft clips pegs

45 8. Pull-Up Don’t Push Down
gelfoam causes middle ear fibrosis reduced aeration? prefer to suspend graft clips pegs

46 8. Pull-Up Don’t Push Down
gelfoam causes middle ear fibrosis reduced aeration? prefer to suspend graft clips pegs

47 Pegged Graft

48 Lifting the Tympanic Membrane
standard 12 to 6 tympanomeatal flap

49 Lifting the Tympanic Membrane
graft pulled into a straight line to peg

50 Lifting the Tympanic Membrane
standard 12 to 6 tympanomeatal flap extended flap for inferior perforations

51 Lifting the Tympanic Membrane
graft pulled into position for coverage

52 9. Craniofacial Anomalies
no difference in success rates!! big difference in canal anatomy big difference in decisions when to operate operate later (surgical bias) actual success rate by age is the same

53 10. Durability all about decisions technique material
timing of operation desired outcomes

54 Bonus Tip watch this space!! tissue engineering
application in the eardrum in use hyaluronic acid/fat graft growth factor and gelfoam

55 Conclusions understand patient’s: each ear is different needs
expectations anatomy physiology each ear is different “Ether Day” (October 16, 1846) by Robert C. Hinckley
