A long-term study of sinoscopic treatment of equine paranasal sinus disease: 155 cases (2012-2019).

Background: There is little objective information concerning the intra- and post-operative complications or the long-term outcome of sinoscopic treatment of equine sinus disorders.

Objectives: To document the long-term outcome, including intra-operative complications, reasons for treatment failure and other complications, in horses undergoing standing sinoscopic treatment of sinus disorders.

Study Design: Retrospective clinical study.

Standing equine sinus surgery.

Trephination of the equine sinuses is a common surgical procedure in sedated standing horses. Standing sinus flap surgery has become increasingly popular in equine referral hospitals and offers several advantages over sinusotomy performed under general anesthesia, including reduced patient-associated risks and costs; less intraoperative hemorrhage, allowing better visualization of the operative site; and allows surgeons to take their time. Other minimally invasive surgical procedures include sinoscopic surgery, balloon sinuplasty, and transnasal laser sinonasal fenestration.

Upper esophageal incompetence in five horses after prosthetic laryngoplasty.

Objective: To describe a complication observed endoscopically in horses after prosthetic laryngoplasty (LP).

Study Design: Case series.

Animals: Horses (n = 5) that had previous LP.

Epidermal-like architecture obtained from equine keratinocytes in three-dimensional cultures.

Despite the high prevalence of skin conditions in the horse, there is a dearth of literature on the culture and biology of equine skin cells, and this is partially attributable to the lack of suitable in vitro skin models. The objective of this study was to develop a three-dimensional (3D) culture system that would support the proliferation and differentiation of equine keratinocytes, similar to that observed in natural epidermis. Cell monolayers were obtained from explants of equine skin and serially passaged as highly pure keratinocyte populations (> 95% of cells), based on their expression of cytokeratins, including CK-5 and CK-14, which are associated in vivo with proliferating keratinocyte populations.

Long-term maintenance of arytenoid cartilage abduction and stability during exercise after laryngoplasty in 33 horses.

Objectives: To (1) assess long-term maintenance of arytenoid cartilage abduction (ACA) after laryngoplasty (LP); and (2) correlate the residual grade of ACA and postoperative abductory loss with arytenoid cartilage stability (ACS) during exercise.

Study Design: Case series.

Animals: Horses re-examined after laryngoplasty (n = 33).

Treatment of a periradicular lesion in an alpaca (Vicugna pacos).

This case report describes the diagnosis and surgical treatment of a cyst-like periradicular lesion in an alpaca.

Race performance after laryngoplasty and ventriculocordectomy in National Hunt racehorses.

Objective: To evaluate the effect of laryngoplasty (LP) on race performance in longer distance (National Hunt) Thoroughbred racehorses.

Study Design: Case-control study.

Animals: National Hunt Thoroughbred racehorses (n=71) and race-matched controls (n=126).

Postoperative race performance is not correlated with degree of surgical abduction after laryngoplasty in National Hunt Thoroughbred racehorses.

Objectives: To (1) assess the degree of arytenoid cartilage abduction lost after laryngoplasty (LP) in Thoroughbred National Hunt racehorses and (2) to correlate postoperative racing performance with degree of arytenoid abduction after LP.

Study Design: Case series.

Animals: National Hunt Thoroughbred racehorses (n=68).

Sinoscopic treatment of rostral maxillary and ventral conchal sinusitis in 60 horses.

Objective: To evaluate the use of sinoscopy for detection and treatment of ventral conchal sinus (VCS) and/or rostral maxillary sinus (RMS) disease in horses.

Study Design: Case series

Animals: Horses (n=60) with suspected paranasal sinus disease.

Methods: Horses were evaluated by sinoscopy through a conchofrontal sinus (CFS) portal with ventral conchal bulla (VCB) fenestration.

A tangential radiographic projection for investigation of the equine temporomandibular joint.

Objective: To (1) describe a tangential radiographic projection of the equine temporomandibular joint (TMJ) and (2) optimize the radiographic angle and determine its use in standing sedated horses.

Study Design: Descriptive study.

Animals: Cadaveric equine skulls (n=11); 8 horses with a history of quidding or headshaking.

Evaluation of the long-term oral consequences of equine exodontia in 50 horses.

The aims of this study were to objectively evaluate and quantify the process of post-extraction cheek teeth (CT) dental drift in horses, and to report on associated disorders of CT wear and long-term periodontal health. Fifty horses that had CT oral extraction because of apical infection were prospectively re-examined and a full oral examination, including measurements of some dental parameters, was performed. Narrowing of the extraction space was noted in all cases with complete closure occurring in 18% of horses.

Trephination of the equine rostral maxillary sinus: efficacy and safety of two trephine sites.

Objective: To examine 2 rostral maxillary sinus (RMS) trephine sites for safety and efficacy using skulls of horses of varying age.

Study Design: Descriptive study.

Animals: Cadaveric equine skulls (n=40).

Ventriculocordectomy as the sole treatment for recurrent laryngeal neuropathy: long-term results from ninety-two horses.

Objective: To evaluate the effect ventriculocordectomy (VC) for treatment of recurrent laryngeal neuropathy (RLN) on exercise performance and owner satisfaction in a mixed-breed population of horses.

Study Design: Retrospective study.

Animals: Adult horses (n=92) with a history of abnormal respiratory noise and RLN.

Use of scintigraphy for diagnosis of equine paranasal sinus disorders.

Objectives: To describe and analyze subjective and objective scintigraphic findings in horses with paranasal sinus disorders.

Animals: Horses with suspected disorders of the paranasal sinuses or cheek teeth (n = 48) and control horses (n = 30).

Methods: 99Technetium-methylenediphosphate (99Tc-MDP; 7500 MBq) was administered for scintigraphic examination of the skull.
