Удаление слюнной железы у собаки.Сиалоцеле.

Сиалоцеле характеризуется воспалением тонкой стенки, колеблющимся и безболезненным. Диагноз подтверждается аспирацией содержимого воспаленной области. Что касается лечения выбора после постановки диагноза, показано хирургическое вмешательство. A salivary mucocele, or sialocele, is a collection of saliva that has leaked from a damaged salivary gland or salivary duct, and has accumulated in the tissues. This is often noted as a fluctuant, painless swelling of the neck or within the oral cavity. While often inaccurately called a salivary cyst, mucoceles are lined by inflammatory tissue (called granulation tissue) which is secondary to the inflammation caused by the free saliva in the tissues. A cyst is lined by epithelial (glandular) tissue which is itself responsible for the production of the fluid. Salivary mucoceles may be classified as follows: Cervical Mucocele: This is the most common type of mucocele. It is a collection of saliva in the upper neck region, under the jaw, or in the intermandiublar region (between the jaws). (Figures 1 and 3) Sublingual Mucocele (also called a ranula): Another frequent location for the formation of a mucocele is on the floor of the mouth alongside the tongue. This is frequently seen in association with a cervical mucocele. (Figure 2) Pharyngeal Mucocele: This type of mucocele is much less common. It is essential a variation of the cervical mucocele, but the fluid accumulation is almost entirely within the throat (pharynx). (Figure 4) Zygomatic Mucocele: This is a very rare type of mucocele where the saliva is originating from the small zygomatic salivary glands which are located just below the eye. The cause of salivary mucoceles is rarely identified, although trauma such as from choke collars, bite wounds, or chewing on foreign materials is generally considered to be the most likely initiating event. As the saliva leaks from the torn salivary gland or duct, it accumulates in the tissue and initiates an intense inflammatory response. A connective tissue capsule gradually forms around the saliva to prevent it from migrating further. This condition is almost exclusively seen in dogs and very rarely in cats. All breeds are susceptible but there seems to be an increased incidence in Poodles, German Shepherds, Dachshunds, and Australian Silky Terriers. There is no age predisposition and this condition may occur at any time.
