Q

In the 2015 study by Langeneckert et al, “Cheek Tooth Extraction Via a Minimally Invasive Transbuccal Approach and Intradental Screw Placement in 54 Equids,” MITSE was found to be favorable when compared to repulsion and invasive lateral buccotomy techniques for which reasons?

A

Repulsion:
- 3/14 (21%) of horses w/ repulsion of mandibular CT developed chronic draining tracts
- 6/30 (20%) of horses w/ entire apical repulsion of maxillary CT developed chronic nasal discharge w/ or w/o oroantral fistula formation (Prichard et al., 1992)
-vs. 2/33 (6%) of animals in this study

Invasive lateral buccotomy techniques:
- 3/112 (3%) of horses developed prolonged or permanent paralysis of the ventral buccal ramus of the facial nerve w/ drooping of the lower lip observed more than 2 months after surgery (O’Neill et al., 2011)

Compressive stresses were predominant on the labial aspect of the alveolar crest and the palatal/lingual aspect of the root tip.

Tensile stresses were predominant on the palatal/lingual aspect of the alveolar crest

The maximum stress in the PDL around the crestal bone and the palatal and lingual aspects of the root apex coincides with the position of initial resorptive lesions in the incisors of affected cases.

Q

In Christiansen’s paper “Standing equine cheek tooth extraction: A multivariate analysis of the effect of antibiotics on the risk of post-operative complications” what was the overall outcome/conclusions?

EVJ 2022

A

Antibiotics were not associated with the risk of complications in 264 horses that underwent standard oral extraction

MTE was associated with a significantly greater risk of any complications, regardless of whether standing oral was combined with antibiotics or not and significance – relative risk 2.32 for MTE

Age was sig assoc with development of complications

MTE not stat sig when additional comparisons made - take with a grain of salt
Age seen as a confounding factor as horses that for abx were typically younger in this cohort

Q

In Townsend’s study “Evaluation of the long-term oral consequences of equine exodontia in 50 horses” what was the rate of dental drift per year?

Townsend TVJ 2008

A

rate of dental drift was calculated as 15.7% of extraction space/year (range 4–50%)
NOT associated with the age at extraction (P = 0.78) or frequency of dental care since extraction (P = 0.48).

There was a significant negative relationship between the rate of dental drift and the duration of time since extraction (P = 0.008)

Q

In Townsend’s study “Evaluation of the long-term oral consequences of equine exodontia in 50 horses” what was the rate of overgrowth of the opposite tooth?

Townsend TVJ 2008

A

98%

Q

In Hopfgartner’s study “Comparison of equine paranasal sinus trephination complications and outcome following standing computed tomography, radiography and sinoscopy guided approaches for the treatment of sinusitis” what were the outcomes related to imaging groups?

Hopfgartner Vet Surg 2024

A

Disease duration was sig longer in cases where CT was used for diagnostics versus cases with no CT imaging
Short-term postoperative complications occurred in 30.1% and were higher in groups using preoperative CT imaging (p = .01), with hemorrhage being the most common surgical complication

Post hospital complications occurred in 45.8% (105/223) of all cases and did not differ significantly between imaging groups
No difference in case resolution among imaging groups

Q

In Hopfgartner’s study “Comparison of equine paranasal sinus trephination complications and outcome following standing computed tomography, radiography and sinoscopy guided approaches for the treatment of sinusitis” what were the outcomes related to disease groups?

Hopfgartner Vet Surg 2024

A

Disease duration was also significantly longer in primary sinusitis versus secondary sinusitis cases
Long-term complications were more common in the secondary sinusitis (99/182; 50.6%) than the primary sinusitis (13/41; 31.7%) group
Short term post-op complications more common in primary than secondary sinusitis

Q

In Pujol’s 2020 study “Suspected primary mycotic rhinitis and paranasal sinusitis in seven horses (2013-2019),” what was the mean number of debridement sessions necessary to remove any necrotic material, and what was the range of time needed to observe complete regression of mycotic plaques?

EVE 2020

A

mean 4 debridement sessions
1-5 months

75
Q

In Pujol’s 2020 study “Suspected primary mycotic rhinitis and paranasal sinusitis in seven horses (2013-2019),” what fungal species was most commonly identified?

EVE 2020

A

Aspergillus spp

76
Q

In Pujol’s 2020 study “Suspected primary mycotic rhinitis and paranasal sinusitis in seven horses (2013-2019),” complete longterm clinical resolution was noted in what percent of cases?

EVE 2020

A

83%

77
Q

In Zetterstrom’s 2021 case report “Meningitis after tooth extraction and sinus lavage in a horse,” what clinical signs were associated with the development of bacterial meningitis?

Journal of Eq Vet Sci 2021

A

Hyperthermia, tachycardia, signs of neck pain

First case report of a horse surviving following diagnosis of suspected bacterial meningitis following treatment of bilateral secondary sinusitis due to apical dental infection
