Age, sex and breed matched horses diagnosed with intermittent DDSP were used as a comparison group. Treatment of all horses was performed by laryngeal tie\u2010forward, 8\/15 horses with persistent DDSP had a subsequent laser staphylectomy. Preoperative laryngohyoid position was compared between the 2 groups using a radiographic reference system. Surgical effect on position was assessed by comparing pre\u2010 and post operative radiographic measurements. Outcome was assessed by return to racing and comparison of pre\u2010 and post operative race earnings ($).\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Results:<\/jats:bold>\n                    Thirteen of 15 horses with persistent DDSP returned to racing. Seven of 15 horses were treated with laryngeal tie\u2010forward alone while 8\/15 horses were also treated with a laser staphylectomy. Horses with persistent DDSP had a more caudal larynx (ossification of the thyroid cartilage) (13\u2003mm, P = 0.014), a more caudal (10\u2003mm, P = 0.044) and dorsal (7\u2003mm, P = 0.01) basihyoid bone, and a more dorsal thyrohyoid\u2010thyroid articulation (10\u2003mm, P = 0.002) than horses with intermittent DDSP.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Conclusions and potential relevance:<\/jats:bold>\n                    Racehorses with persistent DDSP can be treated successfully by laryngeal tie\u2010forward or by laryngeal tie\u2010forward followed by laser staphylectomy.
