Introduction: Temporomandibular joint syndrome is defined by a triad of intense joint pain together with restriction of mouth opening and jaw clicking. It is a syndrome whose prevalence is unknown since it is clearly underestimated.
Aim: This study was carried out with the aim of evaluating the
efficacy and safety of peripheral nerve stimulation for the treatment of this
pathology. The present study highlights peripheral nerve stimulation for the
Treatment of Temporomandibular Joint Syndrome (TMJS).
Materials and Methods: A retrospective analysis of a series of
patients with temporomandibular pain treated by the authors between January
2018 and January 2021 was performed. All patients met selection criteria that
included previous resistance to medical or surgical treatment and completion of
a series of presurgical tests including a sensitivity test. An octopolar
electrode was implanted in the affected preauricular region. The results were
measured using different scales including the VAS or Analogue Pain Scale, a
short questionnaire on pain, improvement in restriction of mouth opening and reduction
of analgesic medication.
Results: A total of 10 patients with 14 procedures performed were
included. The mean reduction in pain measured by VAS was 86.2% at 1 month and
79% at 1 year after surgery. All patients experienced a dramatic improvement in
pain and its impact according to the Brief Pain Inventory, with a mean
improvement of 90% at 4 weeks and 82% at 1 year. An improvement in mean oral
opening of 10.14 mm (minimum 4 and maximum 13 mm) was observed. One case was
excluded due to the complication that required the use of the extraction
system. In this study, the treatment is not only peripheral nerve stimulation
but also includes transcranial magnetic stimulation as a treatment for this
syndrome.
Conclusions: Although temporomandibular joint syndrome affects a
large population, there is no effective treatment in resistant patients.
Peripheral nerve stimulation has proven to be an effective treatment, showing
improvement in pain, oral restriction and quality of life with a low percentage
of serious complications.
