The final part of the book covers surgery of the head and neck in the cat. In the first chapter, conditions affecting all the parts of the head that have not been covered in previous chapters are described, for example salivary gland disease. In subsequent chapters, conditions of the throat area, including the pharynx and larynx are described. Some diseases will affect more than one organ or region; polyps are a notable disease in cats that can affect the middle ear but also have clinical signs that are attributable to a nasopharyngeal location.
Aural anatomy is consistent across most cat breeds so ear disease attributable solely to conformational defects is not common. However, ear disease is still a significant problem in the cat and surgery in the form of partial or complete aural resection can be curative for some conditions, most notably tumors. Surgery for nasal disease is most commonly performed for nasal planum tumors or chronic nasal disease associated with foreign bodies.
Thyroid disease in cats is common and surgery is one treatment option to consider alongside medical management and radioactive iodine therapy. In the chapter on the thyroid and parathyroid gland, decision making with regard to the best treatment for the individual cat is covered.
The feline head is a site that is commonly affected by neoplasia and therefore surgical management of neoplasia, including maxillectomy and mandibulectomy and the resection of brain tumors, is discussed. Although these may be advanced surgical procedures that would be best performed at a specialist center, an understanding of what is entailed is important to be able to discuss the most appropriate treatment options with owners of affected cats.
In the penultimate chapter of the book, management of eyelid and orbital disease is covered. There are already entire textbooks dedicated to ocular disease in the cat and it was not the aim of this textbook to fully cover surgical management of all eye disease in this chapter. Instead, some conditions that might be treated by a more general surgeon, as opposed to an ophthalmologist, are described, such as eyelid surgery and enucleation.
The final chapter provides in-depth descriptions of brain surgery, including pituitary gland resection for pituitary dependent hyperadrenocorticism in the cat, a procedure that is currently being performed at specialist centers to successfully treat this condition.
