Aneurysmal Bone Cyst

Cyst-like lesions that appear radiographically but have no epithelial lining.

Aneurysmal Bone Cyst

A benign lesion of bone that may arise in the mandible, maxilla, or other bones, appearing as a painful, firm pulsatile swelling.

molars

Teeth affected by Aneurysmal Bone Cyst in posterior region

Painful; firm pulsatile swelling

symptoms of Aneurysmal Bone Cyst

no build is heard

During the ausculltation in ABC what is heard

crepitus

what area is palpitated in aneurysmal bone cyts

destructive or osteolytic process with slightly irregular

margins; teeth may be displaced when maxilla and mandible are involved

Apperance of ABC in radiograph

excision or curettage with supplemental cryotherapy

TX of ABC

Traumatic (Simple) Bone Cyst

An empty intrabony cyst that lacks an epithelial lining, believed to be associated with trauma.

Mandible

Area affcted by Traumatic (Simple) Bone Cyst

well-delineated area of radiolucency with an irregular

but defined edge; interradicular scalloping of varying degrees;

occasional root resorption

apperance of traumatic (Simple) Bone Cyst in radiograph

establish bleeding into the lesion before closure upon entry to the

cavity

TX for Traumatic (simple) bone cyts

Static Bone (Stafne's Bone Defect)

An anatomic indentation of the posterior lingual mandible that resembles a cyst on radiograph.

Anterior to the first molar region of the mandible

Area affected by static bone

entrapment of salivary gland or other

soft tissue

The static bone is belived cause by

none

TX for startic bone

Focal Osteoporotic Bone Marrow Defect

Asymptomatic, focal radiolucencies in areas where hematopoiesis is normally seen angle of the mandible and maxillary tuberosity)

radiolucent; often seen in edentulous areas

Apperance of Focal Osteoporotic Bone Marrow Defect in radiograph

incisional biopsy

TX of Focal osteoporotic bone marrow defect

Hematopoeitic bone marrow defect

Other name for Focal Osteoporotic Bone Marrow Defect

Branchial Cyst/Cervical Lymphoepithelial Cyst

Cyst caused by entrapped epithelium in cervical lymph nodes during embryogenesis.

-lateral portion of the neck, anterior to the sternocleidomastoid muscle

-may appear adjacent tot the parotid gland

location of branchial cyts

Intraoral Lymphoepithelial Cyst

Cyst located in the floor of the mouth or posterior lateral tongue

in late childhood or young adulthood.

The branchial cyts appears in

cervical lymphoepithelial cyts

other name for branchial cyts

surgical excision

TX in Branchial cyts

Dermoid Cyst

A cyst caused by developmental entrapment of multipotential cells or implantation of epithelium

located in the anterior floor of the mouth in midline

Area affected by dermoid cyts

Dermoid Cyts

May displace the tongue superiorly and posteriorly when located

above the mylohyoid muscle; below the mylohyoid muscle - midline

swelling of the neck

painless and slow growing

The dermoid cyts is a

less than 2mm

measurement for demoid cyts

soft and doughy because of keratin and sebum in the lumen

when dermoid cyts is palpitated a

surgical excision

TX for dermoid cyts

Thyroglossal Tract Cyst

A cyst related to thyroid gland development, most common developmental cyst of the neck.

Thyroglossal Tract Cyst Development

Develops from residual epithelial elements along the pathway of thyroid gland development.

Most common developmental cyst of the neck

The thyroglossal tract cyts is known as

surgical excision
