BACKGROUND: Purpose of this study was to modify the stethoscope which can
auscultate the temporomandibular joint (TMJ) sounds more precisely than
conventional stethoscope, and fabrication of stethoscope compatible software
which analyses the auscultated sound and gives documentary evidence of that
analysis in the form of graph. MATERIALS & METHODS: The conventional stethoscope
was modified by attaching a custom made soundscope with a recording device which
can be placed in external auditory meatus (EAM) for auscultation of TMJ sounds.
When this small and smooth end of custom made soundscope of modified stethoscope
is placed in EAM & connected with specially developed software it records the TMJ
sounds & analyzes them in form of graph. RESULTS: Fabrication of modified
stethoscope with software records the auscultated sound as a sound wave in form
of graph and analyses this sound wave graph to give graphic evidence of prominent
intensity at prominent frequency as spectrum analysis graph, and duration of that
sound as a sound length graph. CONCLUSION: The use of modified stethoscope with
software increases the accuracy of auscultation of TMJ sounds without any
patient's discomfort and helps in diagnosis of TMJ disorders. The modified
stethoscope with software for auscultation of TMJ sounds results in more precise
auscultation & analysis of TMJ for sounds even of low intensity & frequency. How
