39
Etiology Eagle syndrome

40
Stylohyoid ligament
Ligament that connects styloid process to lesser Cornu of hyoid bone. Flanked by internal external carotid arteries
41
Eagle syndrome is classically associated with
History of tonsillectomy. Surgical fibrosis an area of mineralized complex
42
Eagle syndrome: impingement of ___ will lead to pain
Cranial nerve five, seven, nine, 10
43
Carotid artery syndrome and stylohyoid Syndrome are both
Symptoms of Eagle syndrome, that are not associated with history of tonselectomy
44
Clinical features of eagle syndrome
Vague facial pain, especially during swallowing turning head and opening mouth
45
radiographic features of eagle syndrome
Elongation of styloid process, calcification in stylohyoid ligament complex
46
Treatments for eagle syndrome
Mild: steroid injections. Severe: surgical excision of styloid process or stylohyoid ligament
47
Cyst
Epithelial line cavity
48
Fissural cyst
Cyst deriving from epithelial remnants trapped along embryono lines of fusion
49
Excision/resection
Removal of lesion, part of body or organ by cutting. Equivalent to surgical removal
50
Enucleation
Surgical removal of lesion, tissue or organ in one piece, intact
51
Curettage
Surgical removal by lesion, tissue by scraping (pieces)
52
Marsupialization
Incision of a cyst, conversion of closed cavity to open pouch. Sometimes referred to as decompression. Not curative
53
Palatal cysts of the newborn etiology
Developmental inclusion cysts, Epstein pearls, Bohn nodules
54
Epstein pearls
Palatal cyst of the newborn, median palatal raphe
55
Bohn nodules
