title: [Botulinum neuro-toxin aype-A in the treatment of chronic tension type headache associated with pericranial tenderness].
abstract: OBJECTIVE
  Both peripheral and central nociceptive mechanisms are responsible in chronic TTH. Analgegics are used in the acute treatment of chronic TTH and antidepressants are used in prophylactic treatment. However, further studies are needed to bring out new treatment options. The aim of our study is to investigate the effectiveness of Botulinum Neuro-toxin Type-A (BoNTA) in the treatment of chronic TTH associated with pericranial tenderness (PT).
  
  
  METHODS
  14 patients with chronic TTH with PT were included in the study. 50 units Botox(®) injection was applied to the pericranial muscles (5 units for each muscles bilaterally: frontal, temporal, semispinalis capitis, spenius capitis and trapezius muscles) for each patient. Severity of headache was evaluated by VAS (Visual Analogue Scale) and number of days with headache per month were recorded before treatment and 2nd and 4th months after treatment.
  
  
  RESULTS
  Number of days with headache per month were 19.57 ± 3.25 before treatment, 15.28 ± 4.37 at the 2nd month after treatment and 15.78 ± 3.90 at the 4th month after treatment. Severity of headache was 65.71 ± 9.16 before the treatment, 50.71 ± 13.56 at the 2nd month after treatment and 54.28 ± 10.35 at the 4th month after treatment (p<0.05). Frequency and severity of headache before treatment were significantly decreased at the 2nd month after treatment and this significance continued at the 4th month after treatment (p<0.05).
  
  
  CONCLUSIONS
  BoNTA treatment may be usefull in the treatment of patients with chronic TTH associated with PT.
