The right laryngeal nerve has a simple route, branching off from the vagus nerve, which comes from the brain, and travelling directly to the larynx.
However, the left laryngeal nerve instead must travel all the way to the heart, where it wraps around a large pulsing artery, before coming all the way back to the larynx. It is the longest nerve in the horse’s body and so it stands to reason that it is commonly damaged.
The most common cause of any abnormal respiratory sound is idiopathic left laryngeal hemiplegia (paralysis of the left side of the larynx).
This condition is caused by degeneration of the nerve that supplies the left side muscles of the larynx.
The left side of the larynx consequently “hangs” inward, instead of moving in and out in symmetry with the right side.
Anecdotal evidence from an experienced trainer a few year ago suggested that wind ops on this problem only had about a 50/50 success rate.
One of the problems was when a horse stood up after surgery they could injure themselves or any implants in the operated area could become dislodged.
Tenango was a victim of this breathing disorder and Ian decided to send him to Syrilla Stud for the wind operation and for recuperation.
Tiaan Ellis, stud manager of Syrilla Stud, said, “It was suggested by Dr. Andrew Gray he had to come to the farm for a while before the op so he can just relax and settle down. As Candice Bass-Robinson has mentioned in interviews he was quite a nervy horse and he wasn’t a happy horse, so he came to the farm and we settled him down beautifully. The difference in the wind op procedure was basically that they did it with the horse standing up. I think there was an implant to hold the tie back in place. Then after that he had another almost six months recovery on the farm. We do things a bit differently and give a lot of attention to the horses. We had to hand walk him around the block, because he wasn’t allowed outside to get any dust. So we even hand walked him at night sometimes just to allow him time out of his stable. He also had nasal flushes and was given other attention. He recovered absolutely like a bomb. He changed completely as well from a nervous horse to a happy horse and a very easy horse to work with. It is such a relaxed, no rush environment and he calmed down completely.”
The professionalism employed and the patience displayed has paid handsome dividends as Tenango’s record since the op is seven starts for five wins and two seconds.
Candice Bass-Robinson spoke about his change in demeanour in the winner’s interview on Saturday and said, “He hasn’t been to Hollywoodbets Scottsville, but he is just a consummate professional, he has just got such a wonderful temperament and takes everything in his stride.”
Mark Bass is also a part-owner of Tenango and explained how that came about, “I’m fortunate enough to call Ian a very good friend of mine, we’ve been together at Bass Racing for about 23 years now, and we played a round of golf a few weeks ago and he said, ‘Why don’t you join me for the ride (with Tenango)?’ and I said, ‘I couln’t be more honoured’, so thank you to Ian and Debbie.”
The bay has an exceptional turn of foot and Ian said,” Andrew Fortune, he is quite character, he told us, ‘The horse was saying to me, can we go yet, can we go yet?!’”
Ridgemont have always believed in Canford Cliffs, who won five Gr 1s in succession in Britain and Ireland before being beaten by Frankel in his final start.
He has been firing this season and is just outside the top ten on the national sires log.
The part of Tenango’s story where no luck is involved is Tenango’s transformation in happiness and performance after time was taken to sort out his issues.
The Gr 1 Mercury Sprint over 1200m at Hollywoodbets Greyville on the last day of the season seems the obvious target for Tenango whose merit rating was raised from 118 to 126 and the Gr 2 Post Mechants on Hollywodbets Durban July day is also a possibility.
