The patient is sedated and restrained in lateral recumbency. Traction on a modified sponge forceps applied to the tip of the tongue facilitates exposure of the ventral lingual surface. A tourniquet is placed around the base of the tongue as close to the frenulum as possible, and the operative area is submucosally infiltrated with local analgesic. The elliptical incision begins a few centimetres caudal to the tip of the tongue, ends just cranial to the attachment of the frenulum, and is about 5 cm wide at its widest part in adult cattle [,]: it is important that sufficient mucosa is excised so that a convex shape of the dorsum of the tongue is produced after suturing is complete.

The wound edges are apposed with single interrupted sutures of syn- thetic absorbable material.

The sutures must in- clude not only the mucosa but also some muscle to prevent tearing of the tissue by the sutures [,]. For hours postoperatively the patients re- ceive only water. Nearly all animals will eat im- mediately thereafter, and show no major prob- lems in prehension and mastication of food.

In cases of recent laceration re-apposition and careful suturing must suture material may be used. The sutures are left in place for at least one week []. During this period Surgery. Treatment may be carried out either on the standing animal under ophthalmic antibiotic ointment may be administered twice daily.

The wound and conjunc- tival sac are flushed with physiologic saline. Sharp superficial excision of the wound edges is then carried out with a scalpel, to produce fresh, bleed- ing surfaces. Suturing is begun at the site of the palpebral margin, where a simple interrupted suture is placed [].

The remainder of the wound is then closed. Usually the conjunctiva is not sutured: in any case perforation should be avoided to prevent damage to the cornea.

The orbicularis oculi muscle and skin are sutured together, either with interrupted vertical mat- Chapter I THE H E A D I Eye i-io, i-n i-io Excision of the nictitating membrane Surgery of the third eyelid is indicated in case of tumorous growth, which in horses and cattle usually involves squamous cell carcinoma. Small neo- plasms can be removed leaving an intact nictitating membrane, but larger tumours require total excision [].

The operation is carried out on the standing or recumbent animal under local analgesia.

The base of the third eyelid is infiltrated with a local analgesic after instillation of topical analgesic in the conjunctival sac.

The nictitating membrane is held with a forceps and drawn from the con- junctival sac as far as possible. Complete excision deep to the cartilage is performed using a pair of curved blunt-pointed scissors []. Haemor- rhage is controlled by pressure with a gauze swab soaked in o. Ophthalmic antibiotic ointment is administered in the conjunctival sac for several days [].

The retrobulbar tissues and extra-ocular muscles are dissected bluntly and transected as close to the globe as possible.

In some cases the distal part of the duct is also absent. Surgery is performed under general anaesthesia. A catheter is in- troduced into the lacrimal papilla of either the upper or lower eyelid []. The catheter is then advanced carefully down the tear duct, until the tip is palpable beneath the nasal mucous membrane []. The nasal mucosa and the mucosa of the blind end of the duct are incised over the tip of the ca- theter [], after which the catheter is pushed through the opening cre- ated [].

If accessible, the mucous membrane of the duct is sutured to the nasal mucous membrane with simple interrupted sutures of fine ab- sorbable material. The catheter is then sutured to the skin in the nasal and eyelid regions, and left in place for at least two weeks. If suturing of the mucosal layers is impossible the catheter must be left in place for a longer period weeks , after which time the wound edges have healed and the opening remains patent. The whole operation may be accompanied by considerable haemorrhage, In crib-biting the horse grips a fixed object e.

The neurectomy site is proximal to the entry of the nerve into the muscle; at least 3 cm are removed []. The procedure may be carried out before or after myectomy of the other muscles. The skin is closed with in- terrupted mattress sutures.

At both ends of the wound a drain is placed. Proper functioning of the drains must be checked twice daily, and they must not be removed before 3 days. Postoperatively the horse is confined for about three weeks, and care is taken that the stall contains no objects that may be grasped with the incisors or on which the wound may be rubbed.

The double chromic catgut is threaded through the eye of the needle and pulled through the muscular process. The medial Inspiratory dyspnoea due to laryngeal hemiplegia roaring is a common part of the ligature is brought under the crycoarytenoid muscle using the clinical sign in horses requiring surgical treatment to enlarge the reduced Deschamp's needle.

The needle is then passed, from medial to lateral, laryngeal lumen [o6gA]. Many procedures to alleviate laryngeal hemiplegia through the caudal border of the cricoid cartilage, about 2 cm lateral to the have been utilized.

The mucous membrane of the left laryngeal saccule is removed. The rim of the laryngeal saccule is incised on its caudal border [] and the index finger is brought submucosally to free and then evert the mucous mem- brane. The everted mucous membrane is resected with scissors as close to the base as possible without damaging the adjacent cartilage [].

To prevent foreign body aspiration during recovery and recuperation the skin is closed with a few non-absorbable interrupted sutures. If postoperative dyspnoea occurs a tracheotomy tube is inserted through the laryngotomy wound, or tracheotomy see is performed. Antibiotics are administered.

The vacuum drain is removed after two to three days. The laryngotomy wound is cleansed daily and heals satisfac- torily by second intention. The horse is confined to a box for 4 weeks. After two months at pasture the horse may be returned to training. To enable surgery in the area of the soft pa- sponge forceps.

The aim of surgical treatment is to excise []. After cleaning the laryngeal cavity, the skin is closed with non- the glottis. Prior to laryngotomy, a tracheotomy is performed see The Systemic antibiotics are administered. The tracheotomy tube is removed as patient is placed in dorsal recumbency under general anaesthesia, or under laryngeal swelling reduces and has less effect on respiration. If laryngeal intub- ation is impossible an endotracheal tube must be inserted via the trach- eotomy wound.

The inflated cuff prevents the passage of blood into the lungs during surgery. The skin and subcutanuous tissue are incised in the midline and the ster- nohyoid muscles are separated. The disc to be removed is grasped with lieve dyspnoea caused by acute nasal, laryngeal or proximal tracheal ob- forceps.

Tracheotomy is also indicated prior to some operations on the semi-disc of the tracheal rings proximal and distal to an incision through nose, paranasal sinuses or larynx. Tracheotomy is usually performed on the standing animal under After tracheotomy a self-retaining tube is inserted [] and the skin edges local infiltration analgesia, but may also be carried out on the recumbent are sutured around the tube in a simple interrupted pattern.

After the tube is withdrawn, the tracheotomy wound heals muscles is divided and the trachea exposed. The muscles and skin are by second intention. If temporary tracheotomy is indicated, a tracheal annular ligament is pierc- ed with a scalpel and a tracheal tube ovoid in cross-section is inserted. Its main indication is placing the sutures in the hernial ring.

The chapter dealing with suture materials and needles has been expanded and includes a table of commonly used suture material which is easy to read and allows rapid comparison between different suture types. Similarly the knots and ligatures section has been improved.

Advances in surgery, including arthroscopy for carpal joint surgery, laparoscopy for cryptorchidectomy, and laser techniques as they pertain to upper airway surgery are discussed. This 3rd edition has the feel of a textbook, with important underlying principles as well as the technical step-by-step descriptions of how to perform the procedures, rather than simply being a technical manual.

The illustrations, as with previous editions are a major plus. These, combined with the fact that this is a large animal surgical text not simply equine set it apart from other texts in this field and make this book well worth the download price.
