Background: The treatment and method of rehabilitation of laryngeal
cancer depends on the clinical staging and site of the tumour .The early
detection of laryngeal cancer and less tissue loss leads to good results of
rehabilitation.
Current methods of vocal rehabilitation after total laryngectomy inclurIP
development of esophageal speech, use of electro-Larynx and Tracheoesophageal
fistula with prosthesis. Also the early detection of laryngeal
cancer will make a minor tissue loss after procedures, and so limit the
problems of rehabilitation (speech and swallowing).
Objectives: The aim of this study is to compare the voice results of
patients who underwent total laryngectomy with provox prosthesis and
conservative laryngectomy.
Material and Methods : This study included 2 groups; 19 patients
who underwent laryngectomy for control of laryngeal carcinoma subdivided
into 2 groups according to surgical procedures( 9 patients with total
Laryngectomy with provox processes andl 0 patients with conservative
laryngectomy and 6 normal as control group.
Results: After voice analysis for the two test groups and comparison
to the control group, there was significant difference between conservative
group and provox group as regards intelligibility score and number of
words per minute and also Shimmer and noise to harmonic tests.
Conclusion: of this study showed that conservative laryngectomy
group is relatively better than provox group in many parameters of analysts;
this may be due less tissue loss in conservative group. |
