Canine sialocoeles ‐ 60 clinical cases

Abstract

Sixty cases of canine sialocoele were reviewed from the records of the Sydney University Veterinary Teaching Hospital. Poodles, dachshunds and Australian silky terriers were significantly over represented in the survey when compared to the hospital sample population (P&0.01). No other statistically significant breed, sex, or age trends were noted. Neoplasia was associated with sialocoele formation in three cases. The sialocoele location was cervical (42), sublingual (four), pharyngeal (four), not recorded (one) or in more than one site (nine). Thirty‐five of 39 surgically treated cases were managed by extirpation of the mandibular and sublingual salivary glands together with drainage. Few complications were recorded. Forty‐two per cent of the cases had received previous veterinary treatment in the form of drainage alone. Drainage of saliva from sialocoeles without removal of the offending salivary glands is inappropriate.

Acquired salivary mucoceles in two domestic ferrets (Mustela putorius furo)

“…In a report of 60 cases of canine mucocele, the most common location was cervical (Bellenger and Simpson 1992). All breeds are susceptible, but miniature and toy poodles, dachshunds, Australian silky terriers and German shepherds seem to be more commonly affected (Bellenger and Simpson 1992, Taney and Smith 2010, Benjamino and others 2012). There is a slight predisposition towards male animals (Benjamino and others 2012).…”

Efficacy of Radiation Therapy for the Treatment of Sialocele in Dogs

“…Surgery is the treatment of choice for sialoceles and requires complete excision of the involved gland‐duct complex to be curative . Recurrence of sialocele after surgery occurs in between 5 and 14% of cases.…”

Exophthalmos associated to orbital zygomatic mucocele and complex maxillary malformation in a puppy

“…The zygomatic gland, in comparison with other salivary glands, is the least frequently involved in pathological conditions in dogs (Schmidt and Betts, 1978;Bellenger and Simpson, 1992;Cannon et al, 2011;Nemec et al, 2015). Salivary gland mucocele is a collection of saliva in a cavity lined by granulation tissue that occurs following disruption of a salivary gland or its ducts.…”

“…The mucocele is the most common pathological condition of the salivary glands of the dog, most often involving the sublingual gland, although it can involve the other glands (Karbe and Nielsen, 1966;Bellenger and Simpson, 1992). Zygomatic mucocele is a condition rarely observed in veterinary medicine (Miller and Pickett, 1989;Bellenger and Simpson, 1992;Speakman et al, 1997;McGill et al, 2009), but it should be considered as a possible diagnosis in dogs presenting exophthalmos, protrusion of the third eyelid and a fluctuant, palpable, soft tissue mass around the zygomatic bone (Noghreyan et al, 1996). Since the zygomatic gland is located ventrally to the zygomatic arch, mild changes may not be detected in the early stages of the disease.…”

“…Unilateral exophthalmos in dogs is observed in conjunction with a variety of diseases. The possible differential diagnoses for exophthalmos include primary or secondary orbital neoplasia, inflammatory orbital diseases, orbital varices, and cystic\exudative orbital diseases (zygomatic salivary gland mucocele, hematic cyst secondary to trauma or immune-mediated disease, dacryops, or orbital oedema) (Karbe and Nielsen, 1966;Harvey, 1971;Bellenger and Simpson, 1992;Guinan et al, 2007;Atkins et al, 2010;Adams et al, 2011;Cannon et al, 2011;Philp et al, 2012). Despite the variable underlying causes, the clinical signs of these various conditions are very similar to one another.…”
