Total laryngectomy results in a wide range of physical and psychosocial
sequelae for the patient, including life style changes.1 The most prominent
consequence of this surgical procedure is the loss of the normal voice,
which nowadays often will be rehabilitated with a voice prosthesis, in
our Institute, as discussed in the previous chapters, since 1988 preferably
with the indwelling Provox and more recently with the second generation
Provox2 prosthesis. The disconnection of the upper and lower airways also
has repercussions for the conditioning - warming, humidifying and filtering
- of inhaled air, which is thereby precluded. Consequently, many laryngectomized
patients suffer from respiratory problems, of which involuntary coughing,
excessive phlegm production, forced expectoration and dyspnea are the
most pronounced complaints.2 These symptoms develop and tend to increase
during the first 6 months postoperatively, and probably well beyond that
period, but later seem to stabilize. Frequently, there is an increase
in respiratory symptoms during the winter. Moreover, these problems can
have a serious impact on many aspects of daily life, including increased
fatigue and sleeping problems, compromised voice quality, disrupted social
contacts, and heightened psychological distress.2 Although these problems
are more or less self evident, the awareness about them amongst medical
health care providers has been relatively low in the past.
Furthermore, an objective impairment of the pulmonary function
of the laryngectomized patient can be expected as well. Pulmonary function
assessment should be performed with an extratracheal device (e.g. Provox
HME adhesive, see figure below)3. If an intratracheal cuffed-cannula is
used, the flow-volume loop suggests lower (incorrect) values (see upperfigure,
inner dotted curve). It could be established that the actual measured
pulmonary function values of the laryngectomized patients studied are
significantly lower than the (age, sex, height and race adjusted) predicted
values.4 Moreover, there seems to be an additional independent adverse
effect of the laryngectomy in the older patient group. The above-mentioned
differences were more pronounced in the over 65 years of age group. |
