Partial Laryngectomy Flashcards
The goal of a __________ is to effectively remove the cancer while maintaining physiological breathing, swallowing and voice production.
Partial laryngectomy
What are three potential problems of a partial laryngectomy:
- airway breathing and safety
- swallowing safety
- voice quality and quantity
Describe a Cordectomy:
Stripping or removal of a vocal fold. The arytenoids are usually left in place to preserve laryngeal function. Use activating or relaxing voice techniques depending.
What are problems with cordecomty:
- usually relatively minor changes of voice quality and effort
- Hyperfunctional compensation
- postoperative soft and insufficient voice.
The goal of therapy after a cordecomty is to identify ______ and _______ problems and identify _________
anatomical and physiological problems and identify vicious cycles of maladaptive behaviours.
Describe techniques of reducing hyperfunctional compensation (pressed/ forced phonation):
Relaxation:
- smooth, easy phonation
- increase utterance length
- control speech rate via phrasing tasks
Describe techniques of reducing postoperative soft and insufficient voice:
Activating:
- careful pushing
- other activating exercises
Describe a Hemilaryngectomy:
If a tumour has spread along the VF as well as vertically the surgeon may resect half of the larynx including the arytenoid.
Describe a vertical partial laryngectomy:
A more confined vertical resection where the arytenoid is left in place.
Problems of a vertical partial or hemilaryngectomy:
- variable depending on the operative technique used
- higher F0s and shorter durations for sustained vowels
- ventricular fold phonation if VF can’t approximate
A therapy goal for a vertical partial or hemi-laryngectomy is to:
- identify the predominant source of voicing (glottal vs ventricular)
- identify point of easiest phonation from subsequent vowel phonation tasks
- Decrease utterance length to manage pulmonary support
Describe the supraglottic subtotal laryngectomy:
- All laryngeal structures above the VF are removed.
- Leave the vocal folds and arytenoid for voice and airway protection.
- Patient may require a tracheostoma
- Voice quality and quantity are often poor. Tracheo-esophageal voice may actually be a better option.
What structures are removed in the supraglottic subtotal laryngectomy:
Epiglottis, ventricular folds, hyoid and thyroid cartilage.
Problems of supraglottic subtotal laryngectomy:
- high risk of aspiration which can lead to overadduction of the VF and hyperfunctional voice problems.
The treatment goal in supraglottic subtotal laryngectomy is to ___________ and ______
eliminate aspiration and re-establish phonation
Describe Supracricoid partial laryngectomy with cricohyoidoepiglottopexy:
A variation of the supraglottic laryngectomy
- Hyoid and the epiglottis are preserved. Surgical pull-up of the cricoid to the hyoid results in better swalllowing safety and voice quality.
T or F: The supracricoid partial laryngectomy with cricohoidoepiglottopexy provides more structure and provides patients with slightly better voice quality and slightly safer swallowing than the supraglottic laryngectomy.
