When the lip is detached from the underlying tissue, often along the mucogingival line
usually due to shearing trauma - ANS what is a labial avulsion and what causes it?
surgical reconstruction: interdental stent sutures to support weight of lip, then suture
mucogingival junction. use button, esp. on bottom lip to maintain even pressure
effective for maxillary, not mandibular lesions due to gravity - ANS what is the treatment for
labial avulsion?
there is very little soft tissue left for reattachment- often dehisces - ANS why is it hard to fix a
labial avulsion?
species and breed differences in face structure
lesion size and location- especially proximity to mucocutaneous junction - ANS what
considerations should you have when doing lip surgery reconstruction?
direct apposition: for small, angular incisions
labial advancement flap: for removal of a medium to large sized section

,labial rotation flap: for large removals, usually skin is pulled from the neck - ANS what labial
reconstruction options do you have?
mucocele due to trauma, sialoadenitis, or sialoliths
salivary gland enlargement due to canine necrotizing sialometaplasia or neoplasia - ANS what
are the most common salivary gland disorders and what causes them?
adenocarcinoma
in dogs involves parotid
in cats involves mandibular - ANS what is the most common neoplasia of the salivary gland in
dogs and cats and which gland is most involved?
L1A slide 18
cats have an additional major salivary gland: molar salivary gland - ANS review the major
salivary glands in dogs and cats. how do they differ?
subcutaneous accumulation of saliva within a non epithelial, non-secretory lining
appears as soft, non painful swelling that may fluctuate. may be painful if secondary infection or
acute inflammation occurs. most comonly at the cervical region, but may also appear at the
pharyngeal region or under the tongue (RANULA) - ANS what is a salivary mucocele and how
does it appear?
German Shepherd and Poodle - ANS what breeds more commonly have salivary mucocele?
sublingual, often with involvement of the mandibular

,these two glands are too closely associated to only excise the sublingual - ANS what gland is
most commonly involved in salivary mucocele?
surgical removal of involved glands is definitive treatments
percutaneous aspiration of accumulated saliva for high risk patients
marsupialization of ranula
lancing pharyngeal mucocele prior to surgery to relieve respiratory distress - ANS how do you
treat a salivary mucocele?
lance the ranula, then tack it open so that it will drain and not close up.
used in high risk patients
may recur - ANS what is marsupialization of a ranula?
make a horizontal incision over the effected gland. do not cut the digastricus muscle, but pull
the mandibular and sublingual salivary glands under it so that you may completely excise the
two glands by tracing it to the oral mucosa near the sublingual caruncle.
either drain the mucocele during surgery, or place a drain if this is not possible
vertical incision for parotid gland - ANS generally, how do you excise the mandibular and
sublingual salivary glands?

, excellent, recurrence is rare
most common reasons for failure: inadequate excision, removal of wrong gland or structure -
ANS what is the prognosis for surgical excision of salivary mucocele?
cats: not very common, 3-10%
dogs: 4th most common neoplasm - ANS how common are oral tumors in dogs and cats?
melanoma - ANS what is the most common malignant oral tumor of dogs?
malignant: mucocutaneous and nail bed
benign: haired skin - ANS what melanomas are usually malignant? benign?
more common in males and small breeds
may be melanotic or amelanotic
malignant, locally invasive, mets early to regional lymph nodes and lung - ANS what are the
general characteristics of oral melanoma?
gingiva > labial and buccal mucosa > palate > tongue - ANS where are oral melanomas most
likely to occur?
surgical resection with biopsy of reginal lymph nodes (mandibular, parotid, retropharyngeal)
radiation therapy with sx or for non surgical tumors
