TMJ ANKYLOSIS…
= aka?
due to…
treatment?

A

= aka FUSION OF JAW

due to…
–> FIBROUS/BONY UNION between MANDIBLE & TEMPORAL BONE or ZYGOMATIC ARCH

treatment?
= we can REMOVE the fused area but chance of recurrence, so BETTER TO REMOVE PART OF THE JAW

MASTICATORY MUSCLE MYOSITIS

can see ATROPHY of TEMPORALIS/MASTICATORY muscles!

18
Q

what DISEASE is indicated by BRIGHTNESS/HYPERATTENUATION? what PATHOLOGIC finding is it showing?

what 2 things should we rule out before jumping to this diagnosis?

A

MASTICATORY MUSCLE MYOSITIS, it’s showing INFLAMMATION

2 rule-outs?

Q

SIALOCELES
= definition?
what is this NOT?
what GLAND is most commonly affected?
4 types?
how to diagnose which gland is affected?
treatment? (1)

A

= ACCUMULATION OF SALIVA in SUBMUCOSAL or SQ TISSUE due to RUPTURE of GLAND/DUCT

this is NOT A CYST

SUBLINGUAL gland is MOST COMMONLY AFFECTED

4 types?
1. PHARYNGEAL
2. CERVICAL –> usually PAROTID salivary gland
3. SUBLINGUAL
4. PERIORBITAL

diagnosis?
–> usually PUT CONTRAST MEDIUM INTO SALIVARY DUCT do CT to see WHAT GLAND IS AFFECTED/HAS LEAKAGE

treatment?
–> EXCISION OF THE GLAND or DUCT COMPLEX

22
Q

ID DZ & GLAND AFFECTED
