L8 Flashcards
True Cysts
Contain epithelial lining
Treatment similar for inflammatory and developmental cysts
Cysts do not cause extrabony expansive growth like tumors can
Enucleation
Remove entire cyst without rupture
Fibrous CT wall allows cleavage plane between lesion and bony cavity
indicated anytime cyst can be removed without injury adjacent structures
Enucleation +/-
history exam
disadvantage pathological fracture tooth devitalization nerve injury
Enucleation and Curretage
enucleate first then mechanical curettage removes 1-2 mm bone at entire periphery of bony cavity
OKC-known aggressive cysts
Marsupialization
OPen cystic lesion and maintain latency to adjacent cavity
attach lining to oral/nasal cavity or maxillary sinus
cyst results from chronic inflammation decrease pressure–> shrinks–> bony fill
Staged Marsupilization and enucleation
More commonly performed than marsupial’s alone
makes cyst small for final E&C later
Staged Marsupilization and enucleation indications
concern for injury to adjacent anatomy
large lesions
marsupulization alone does not resolve
need to examine entire lesion history to give final daingoes
Staged Marsupilization and enucleation +/-
+ developer thickened linied
reduced morbidity and accelerates complete healing
same as marsup
Developmental cyst
Dentigeours OKC Lateral period Galndular odontogenic Calcyfing odontogenic cyst
Denitgerous and OKC
EXT tooth and E and C
Lateral periodontal cyst
Enculation with tooth preservation
Glandular odontogenic cyst
E and C some advocate more aggressive treatment
Calcifiying odontocye cyst
E and C
Jaw Tumor Management epithelial
Epithelai: Ameloblastoma adenmatoid and squamous odontogenic tumor CEOT
Jaw Tumor Management mixed
ameloblastic fibroma and fribodontoma odontoma
