Q

type of velopharyngeal closure?

A

coronal patterns, which are caused by posterior movement of velum with less contribution from the lateral pharyngeal wall
Sagittal closure is predominantly attributed to medial
movement of the lateral pharyngeal wall.
Circular closure is seen when there is good motion of velum as well as lateral pharyngeal wall

Bowtie
closure is seen primarily with movement of velum and posterior
pharyngeal wall causing poor or minimal motion of the lateral pharyngeal wall

Q

The advantage of MRI over NPS and VFS

A

The advantage of MRI over NPS and VFS is that it is noninvasive and avoids the
exposure to ionizing radiation

30
Q

Draw back of the MRI

A

the poor image quality, when images are obtained during active phonation

31
Q

Nasometry uesd to measure …….

A

measurement of oral and nasal air pressure and flow and calculation of velopharyngeal port size

32
Q

Nasometry is one of the few tools that indirectly provide objective assessment of velopharyngeal mechanism

A

T

33
Q

The drawback of nasometers

A

the criticism of its use is its oversimplification of the VPD mechanism and its inability to predict the location of gap size

34
Q

An orifice of
>10 mm’ has been shown to correlate with hypernasality in nasometer

A

T

35
Q

What are important anatomic factors that should be considered in selecting
an optimal surgical procedure for the treatment of VPI?

A

Size of the defect, closure pattern, and lateral wall motion

36
Q

functional repairs of VPI add tissue from the adjacent area

A

F functional repairs yield a more anatomic local tissue rearrangement of structures in the soft palate, without adding tissue from neighboring areas

37
Q

Risk of OSA. increase with functional repair of VPI

A

F. functional repairs inherently have less risk of obstructive sleep apnea (OSA) and should be attempted whenever possible to reduce the risk of long-term airway complications as the patient ages

38
Q

Sommerlad et al. advocated that radical intervelar veloplasty should be considered as the first-line option in patients with
VPI

A

T

39
Q

Functional Palatal Lengthening Objectives?

A

To achieve lengthening of the soft palate with retro positioning of levator muscle in the velum and closure of a small gap in
the VP port

40
Q

The outcome of furlow surgery in VPI?

A

Furlow resulted
in significant velar elongation, increased acuity ofthe genu angle, and
retropositioning of the levator sling

41
Q

tightening of the genu angle can improve the speech

A

T

42
Q

The advantage of functional repair is that reduce the risk of future Obstructive sleep apnea

A

T at the cost of up to 30% risk of failure (or the incomplete resolution of VPI)

43
Q

Other methods of palatal lengthening rather than Furlow or intervelar velplasty

A

include interpositional buccal flap and V-Y pushback palatoplasty

44
Q

Posterioir pharngeal flap is original design for the pharyngeal flap was
superiorly based

A

F
inferiorly based

45
Q

Difference between the superior and inferior-based pharyngeal flap

A

inferiorly based flaps
are considered easier to attach, and superiorly based flaps have the
advantage of giving a larger flap

46
Q

The drawback of the inferior-based flap

A

limitation of its length and possible inferiorly directed pull onto the velum, which is in contradiction to the
goals of the effective velopharyngeal closure mechanism.

47
Q

Pharngeai flap is suitable for which type of pharyngeal closure

A

patients with sagittal or circularly oriented closure patterns

48
Q

factors that may play a role in the success of pharyngeal flap

A

are flap
width and level of attachment. Flaps that are too wide may be counterproductive by causing symptoms of hyponasality and sleep apnea;
on the other hand, flaps that are not wide enough may be ineffective

49
Q

Pharyngeal
flap is ideally inserted at the level of C 2 to allow adequate elevation
of the velum.

A

F Pharyngeal
flap is ideally inserted at the level of Cl to allow adequate elevation
of the velum.

50
Q

Sphincter Pharyngoplasty Hynes in
1950 utilized which muscle

A

bilateral salpingopharyngeus muscles

51
Q

Recently the most commonly used muscle

A

the most commonly used design
of this procedure entails 90° transposition of the superiorly based
palatopharyngeal muscles

52
Q

Sphincter Pharyngoplasty best suited for saggital closure pattern

A

F It is best suited for a large
the posterior gap with coronal, circular, or bowtie closure pattern and/
or poor lateral wall motion

53
Q

Advantage of Pharyngoplasty?

A

An advantage of sphincter pharyngoplasty procedure is the ability to adjust the port size postoperatively,
if needed by tightening or loosening the muscles.

54

Q

present always with complete cleft palate

A

F Submucous cleft palate

59
Q

Other contributing factors to VPI in syndromic case?

A

increase in the width of space between the velum and posterior pharyngeal wall, asymmetric displacement of lateral pharyngeal wall reduced adenoid size, and intellectual disabilities

60
Q

The importan of nasendoscopy in syndromic VPI ?

A

During nasal endoscopy, attention
should also be paid to the presence of pulsations in the posterior or
lateral pharyngeal wall which may suggest medialization of internal carotid arteries
