Concomitant depression and anxiety negatively affect pain outcomes in surgically managed young patients with trigeminal neuralgia: Long-term clinical outcome.

BACKGROUND

Onset of trigeminal neuralgia (TN) is uncommon in young adults with less favorable benefit from surgical interventions. The aim of this study was to evaluate the role of concomitant psychosomatic disorders in long-term surgical outcomes in this population.

METHODS

Twenty-one patients younger than 30 years of age were diagnosed initially as having medically refractory TN, and each patient underwent microvascular decompression (MVD) as initial surgical management. Correlation of clinical outcome and psychosomatic disorders (DSM-IV) was evaluated during a 15-year interval.

RESULTS

A total of 93 procedures were performed for the management of TN and subsequent iatrogenic craniofacial pain disorders. At a median of 81 months, 8 of 21 patients were free of facial pain. Fourteen patients with concomitant major depressive disorder (MDD) or other anxiety disorders underwent a higher median of procedures compared with 7 patients without known MDD or anxiety (4.5 versus 1 intervention, = 0.038). Two of 14 patients who were diagnosed with MDD or other anxiety disorders were free of craniofacial pain, whereas 6 of 7 patients without mood or anxiety disorders were free of craniofacial pain ( = 0.0005). Thirteen patients developed treatment-related complications that required further surgical procedures. Presence of MDD or other anxiety disorders was associated with higher rate of complications ( = 0.026). One patient with past medical history of severe anxiety died of unknown causes.

CONCLUSIONS

In young patients with TN, comorbid MDD or anxiety disorders was associated with seeking multiple invasive procedures in multiple academic centers with limited benefit and high rates of surgical induced complications.
