Miscellaneous Flashcards
Bells palsy?
Paralysus or weakness of the CN7 unilaterally
Trigerring events for bells palsy
Otitis media
Atmospheric change
Ischemia if facial nerve near stylomastoid foramen
Melkerson rosenthel syndrome
Multiple sclerosis
Herpes virus
Trigemin neuralgia also known as
Tic douloureux
Features of trigeminal neuralgia
Trigger point
Very sudden stabbing pain
Electric shock like
Less than 2 mins
Refractory period follows
Follows trigeminal branches
Sharp stabbing pulses of pain in the back of the throat tongue and tonsils and middle ear during swallowing drinking cold sneezing coughing talking touching the gums or throat
Glosspharyngeal neuralgia
Nerve pain follows shingles, confined to the area where shingles were, severe stabbing burning pain with no clinical findings
Post herpetic neuralgia
After parotid gland surgery, auriculotemporal nerve healed and innervaged sweat glands of the face resulted in GUSTATORY SWEATING during eating
Freys syndrome
Auriculotemporal syndrome
Autoimmune neuromuscular disease leads to muscle weakness and fatigue, difficulty in eating, double vision, flat smile, droopy eyes , xerostomja and rampant caries
Myasthenia gravis
Oral manifestations of myasthenia gravis
Weakness- MOM, palate, pharynx larynx tongue
Lack of strength in masseter muscles
Dysphagia
Expressionless
Gingival hyperplasia due to cyclosporine
Chronic autoimmune disease attacks CNS of females of 20-40yrs of age leads to tingling and numbness to paralysis and blindness - bells palsy and trigeminal neuralgia
Multiple sclerosis
Chronic inflammation of minor SG affecting lower lip that results in hypertrophy and inflammation of glands
Erosions and ulcers are seen too
Cheilitis glandularis
Non caseating granulomatous inflammation of the lip
Cheilitis granulomatosa
Melkersson rosenthal syndrome
Cheilitis granulomatosa
Facial paralysus
Fissured tongue
Exfoliative cheilitis
Ch inflammation on lips
Crusting scaling erythma vermillion border
Excessive production of keratin
Occurs in females
Premalignant condition affects middle aged men due to longterm exposure of sunlight causing chronic degenerative disorder if the lower lip
Actinic cheilitis
Macrophage cells fuse together to form multinucleated giant cells
Langerhans giant cells
Granulomatouse inflammation cane be seen in
TB
Histoplasmosis
Syphillis
Sarcoidosis
Crohn disease
Cheilitis granulomatosa
ESR rises in
Inflammation
Tissue degeneration
Suppuration
Malignancy
Necrosis
Pregnancy
Effects of radiotherapy on oral cavity
Mucositis - 2nd week
Loss of taste - 2-3rd week
Xerostomia - parotid gland radio sensitive
Radiation induced caries
Trismus - damage to vasculature of muscles
Due to ischemia, hypocellularity, hypovascularity - exposed bone fails to heal longer than 3 months after high dose of radiation
Osteoradionecrosis
Underlying tissue architecture is preserved for several days after death of cells in the tissue
Coagulative necrosis
Cheeselike friable yellow white app of the area of necrosis
Caseous necrosis
Loss of architecture
Complete digestion
Transforming the tissue into a viscous liquid removed by phagocytes
Liquiefactive necrosis
Limb lost its blood supply undergone coagulative necrosis involving multiple layers of tissue
Gangrenous necrosis
