Abstract

Objective: To compare the effectiveness of locally made phonating device with oesophageal speech as a communication method in a laryngectomized patient.
Study Design: Randomized Controlled Trial.
Place & Duration of Study: Combined Military Hospital Lahore from January 2004 to July 2007.
Patients and Method: Twenty five patients who had undergone total laryngectomy were divided in two groups by random sampling. 13 patients were placed in experimental group and provided with a locally made phonating device EL (Electro-larynx, ‘BM Talk’) and speech training with this device started between 20th to 30th post-operative day. The results were compared to a Control Group consisting of 12 laryngectomized patients who were provided instruction and training on oesophageal speech for communication. Speech assessment was made at the end of 2nd, 4th and 6th month post-operatively in both the groups. Assessment parameters were defined according to the patient’s ability to communicate ten predetermined sentences of Urdu and Punjabi to a team of three speech assessors on each speech assessment day. Speech communication score was fixed at 100 if all the spoken sentences were fully understood by all the three assessors irrespective of character of speech, while it was 0 if none of the sentence spoken could be understood by any of the three assessors. In between the two were different percentages of speech communication scores depending on the number of sentences understood by the speech assessors. The character of voice was assessed by Visual Analogue Score where variation between robotic and normal speech character were divided into ten grades from 1 to 10.
Results: At the end of six months, speech communication score was 76.62 with SD 17.29 for EL (Electro-Larynx); while for control group (oesophageal speech) it was 34.17 with standard deviation of 8.63. Those score was compared by using t test and was highly significant i.e. <0.001 in favor of EL. The character of voice was closer to normal in case of oesophageal speech compared to EL where it was closer to robotic.
Conclusion: Locally made EL (Electro-larynx) ‘BM Talk’ is a useful device for speech rehabilitation in laryngectomised patient. It has added advantage of local availability and cost effectiveness. The character of voice may be robotic and monotonous, nevertheless full sentence can be communicated with relative ease to the listener, which is more important factor in our setup.
