for smaller tumors on the TVF,
|
radiotherapy is the more frequent treatment choice
|
|
cure rates for these small tumors are usually
|
equal with radiotherapy or surgery
|
|
the larynx is divided into ____ areas for staging
|
3 supraglottis, glottis, subglottis
|
|
__ percent of tumors occur in the glottic area
|
60%
|
|
___ percent occur in the supraglottic araea
|
35%
|
|
___ percent in the subglottic area
|
5%
|
|
because of the way in which the lymph system drains in the supraglottic larynx, a tumor of the supraglottic larynx will ______
|
not spread downward to the true vocal cord and/or subglottic larynx unless the tumor is located at the base of the epiglottis
|
|
supraglottic laryngectomy
|
part or all of the hyoid bone and epiglottis, the aryepiglottic folds, and the false vocal foldes
|
|
it leaves the ________, __________, and ______ as athe only protective mechanism
|
base of tongue, arytenoids, TVF
|
|
in reconstruction the surgeon usually
|
elevates the remaining larynx and tucks it under the tongue base for additional protection during swallow
|
|
laryngeal suspention is also affected becuase
|
the hyoid bone is partially or completely removed
|
|
the tongue base has to make complete contact
|
with the posterior pharyngeal wall because otherwise residue will fall directly into the airway because the patient with a supraglottic laryngectomy has no valleculae and smaller pyriform sinuses than normal
|
|
the supraglottic laryngectomy can also be extended
|
inferiorly to include part of one vocal fold, or oan arytenoid cartelage. the patients change of normal recovery are slim b/c no protection of airway
|
|
long term study of supraglottic laryngectomy (normal after how long?)
|
patients with a dtandard resectionwere able to swallow a normal diet at an average of 1 month after surgery
|
|
those patients with an extended supraglottic to include arytenoid spent a min of ____ months and more frequ ______ months attempting rehab
|
2, 6-12. some could never drink liquids
|
|
supraglottic with extension to the tongue base - often took
|
6 months or more. some never gianed enough tb movement to protect the airway
|
|
tongue base and arytenoid range of motion exercisdes have an effect within the first
|
2-4 weeks. exercises can be contingued
|
|
some pateints attain successful airway protection __ months
|
3-4 months after surgery if they contine to exercise
|
|
if possible, the onset of postoperative radiotherapy should be
|
delayed until oral intake is reinstated
|
|
tumors located on the free margin of one VF with only local extension are usually treated with
|
vertical laryngectomy or hemilaryngeactomy. or an extended hemi
|
|
hemilaryngectomy includes
|
one false VF, one ventricle, and a true vocal fold, usually excluding the arytenoid cartelage as well as the thyroid cart.
|
|
in hemi, pateitn experiences few dificulties swallowing because some tissue bulk
|
is reconstructed on the operated side, against which the unoperated side can attain normal laryngeal closure during swallowing
|
|
reconstructed side must be at the same _________
|
level
|
|
usually, tipping the patients head
|
forward to push the epiglottis more posteriorly and narrow airway entrance helps
|
|
patients need chin down for only
|
a few weeks postoperatively if they were aspirating
|
|
sometimes the hemi has to involve the anterior commisure and patients
|
wwill rpobably be rehabd within 2-3 weeks but more may need chin down at first
|
|
when the arytenoid cart is included in teh resection,
|
the patient's chances of returning to normal swallowing with no aspiration are greatly decreased.
|
|
if aspiration is controlled by reconstructing a narrow glottic chink,
|
the airway is usually compromised and the functional tradeoff for elimination of aspiration is a perminant trach
|
|
large lesions (T3 or T4) involving more than one region of the larynx usually require
|
total laryngectomy or high dose radiation with or without chemo
|
|
with a pseudoepiglottis, the greater the struggle reaction of the patient
|
the greater the widening of the picket and the more severe the difficulty in swallowing
|
|
dilatation of the esophagus scar tissue stricture has to be repeated
|
often monthly
|
|
both a pseudoepiglottis and a ________ can result in
|
stricture. backflow of food as the patient struggles to swallow
|
|
if a total laryngectomy patient has not returned to a full preoperative diet at ________ months postop, ____
|
2 months, a full radiographic study of oropharyngeal and cervical esophageal aspects of swallow should be completed.
|
|
TE puncture
|
successful
|
|
if the puncture site in the TE puncture is too large
|
the surgeon can cauterize it.
|
|
patients who are candidates for the te puncture a __________ for prevention of ___________
|
myotomy, pharyngospasm
|
|
after total laryngectomies, patients do increase
|
lingual pressures to compensate for the absence of the larynx and reduced pharyngeal wall function postoperatively
|
|
ROM exercises should be done
|
5-10 times daily for 10 min. each time at beginning of radiotherapy or at the beginning
|
