SESAP - H&N Flashcards
Central Neck Borders
Superior - hyoid bone
Lateral - carotids bilaterally
Posterior - superficial and deep layer of the cervical fascia anteriorly
Innominate artery on right
Thyroid cancer
Most likely histologic variant?
Locoregional recurrence rates? LN micromet?
Papillary
25-50% LN micrometastasis
Branchial cleft
First Arch
Structures?
Middle ear, eustachian tube, EA canal.
Branchial cleft
Second Arch
Structures?
MC to hav an anomaly (incomplete obliteration of cleft to result in pouch)
TONSIL!
Branchial cleft
Third Arch
Structures?
Inferior Parathryoid,
Thymus
Branchial cleft
Fourth Arch
Structures?
Superior parathyroid
C-cells
Branchial cleft Second Arch Classification? Workup? What to do?
along Glossopharyngeal NN, hypoglassal nn
b/t int/ext carotic
classified as being superficial, within or adjacent to carotid sheath
ALWAYS FNA to r/o malignancy in adults
ALWAYS EXCISE complete cyst and tract. NOT acutely infected
Spinal accessory nn What cranial nn? Where does it exit? What does it innervate? What action?
CN 11
Jugular foramen through SCM, diagnoally across posterior triangle and into trapezius
trapezius - MOTOR fibers, SCM - MOTOR
Weak shoulder abduction, drooped shoulder
Salivary gland tumors
rule of thumb?
- salivary tumor is dir. proportional to size of gland
- malignant potential is INV proportional to size of gland.
Larger gland - larger tumor - low malignant potential!
Parotid tumor
MC benign tumor?
Workup?
Treatment?
Pleomorphic adenoma
FNA and assess LN
Superficial parotidectomy
Typical patient for Warthin’s
- Bilateral
- Male
- Smoker
Thyroglossal duct cyst
presentation?
w/u?
treatment?
- midline, moves with swallowing.
- remnant tract of migrating thyroid
- U/S and thyroid scan (assess that this is not the only thyroid tissue patient has)
- Sistrunk.
Recurrent laryngeal nerve
location of parathyroids?
Superior - BEHIND lateral
Inferior - In FRONT medial
Intra-operative nerve monitoring - role
Inc cost. Inc time. No utility for routine sx.
ROLE for REPEAT neck procedures to decrease RLN injury.
Parotid injury
Lie of duct?
Parotid duct is anterior along the parotid gland which is by the masseter muscle.
