URT

Question 1

Sinoscopy portal for conchofrontal sinus

Answer 1

Conchofrontal:

60% of the distance from midline to the medial canthus and 0.5cm caudal to the medial canthus

Question 2

Trephine site for a modified frontonasal bone flap technique

Answer 2

5cm axial to the nasolacrimal duct
4cm lateral to nasal midline
2cm below a horizontal line between the medial canthi

Question 3

Sinoscopy portal for RMS

Answer 3

RMS:
40% of the distance from the rostral end of the facial crest to the level of the medial canthus and 1cm ventral to a line joining the infraorbital foramen and the medial canthus

Question 4

Sinoscopy portal for CMS

Answer 4

2cm rostral and 2cm ventral to the medial canthus

Question 5

Borders for a maxillary bone flap

Answer 5

ROSTRAL: line from rostral end of facial crest to infraorbital foramen

DORSAL: line from infraorbital foramen to medial canthus

CAUDAL : line from medial canthus to caudal facial crest

VENTRAL: facial crest

Question 6

McGivney et al, EVJ, 2019, uses exploratory factor analysis to identify signalmen and conformational traits associated with RLN. What were the main findings?

Answer 6

Height, neck length and body size were the most significant factors (in order). Wither height significantly loaded height, ventral neck length significantly loaded neck length and body weight, neck circumference and males were correlated with body size

Question 7

Krueger et al, JAVMA, 2019 assessed RLN and PL in QH. What were the findings?

Answer 7

RLN and PL did not negatively affect QH.
Odds of returning to racing didn’t differ significantly btw case and control horses but decreased with increasing age. Racing starts and career longevity were not affected by RLN grade or PL.
