Evidence-based equine upper respiratory surgery.

This research paper reviews veterinary literature about surgical procedures for upper respiratory conditions in horses, aiming to evaluate the scientific evidence supporting different therapies. It mainly focuses on procedures for common conditions like laryngeal hemiplegia, dorsal displacement of the soft palate, arytenoid chondritis, and epiglottic entrapment.

Understanding the Scope of the Research

• The research involves the review of veterinary literature regarding several surgical procedures of the equine upper respiratory tract. This indicates that this paper is fundamentally a literature review, in which the researchers analyse the existing studies about these procedures in horses.
• The objective is to assess the level of supporting evidence behind different therapies. This means the researchers examine the data, methodologies, and outcomes of previously conducted studies to derive conclusions about the effectiveness and efficiency of the individual procedures.

Focused Conditions in the Study

• The research predominantly concentrates on four widely occurring conditions: laryngeal hemiplegia, dorsal displacement of the soft palate, arytenoid chondritis, and epiglottic entrapment.
• ‘Laryngeal hemiplegia’ is a medical condition where the nerve that controls the muscles and cartilage that opens and closes the larynx doesn’t function optimally, resulting in restricted airflow during exercise.
• ‘Dorsal displacement of the soft palate’ is an obstruction of the airway caused by the soft palate – the flexible part of the roof of the horse’s mouth – moving into an abnormal position.
• ‘Arytenoid chondritis’ is an inflammatory condition of the arytenoid cartilages, which are part of the larynx and are responsible for allowing or blocking passage to the windpipe.
• ‘Epiglottic entrapment’ is when the thin, leaf-like structure located at the base of the tongue, the epiglottis, becomes covered by a pocket of tissue, hindering its function during swallowing and respiration.

Significance of the Research

• This research is significant because it aims to provide an evidence-based perspective on the treatment options available for typical equine upper respiratory tract conditions.
• By summarising and evaluating existing research, the study might suggest the most effective surgical procedures and help equine veterinarians make informed decisions about therapy selection.
• This study might also identify areas where further research is needed, in cases where evidence supporting a particular treatment option is inconclusive or lacking.
