Use of triple-convergence polypropylene thread for the aesthetic correction of partial facial paralysis caused by the facial nerve injury.

OBJECTIVE

To evaluate the use of self-sustaining triple-convergence polypropylene thread for correction of hemiface deviation presenting as late result of facial paralysis.

METHODS

We conducted a retrospective, observational study with 34 subjects with late facial paralysis. We used a triple-convergence polypropylene thread to correct the deviation of the paralyzed hemiface. It is a monofilament, synthetic, transparent and unabsorbable thread that has hooks that exert traction in the ptotic tissues, keeping them in the correct position, in symmetry with the healthy side. The results were evaluated by subjective analysis, with assessment of patient satisfaction with a proper questionnaire.

RESULTS

We analyzed 34 patients, 73.52% of them reported great improvement, 20.58% moderate improvement and 5.88%, slight improvement; we found a high satisfaction rate of 94.1%. Two patients had partial extrusion of the wire. No patient developed infection.

CONCLUSION

The use of triple-convergence polypropylene thread to correct the deviation of hemiface consequent to facial palsy markedly improved facial asymmetry and recovery of patients' self-esteem.
