Autogenous palmaris longus tendon as frontalis suspension material for ptosis correction in children

Purpose:
To determine the safety and efficacy of autogenous palmaris longus tendon as a sling material in frontalis suspension surgery for ptosis correction in children.
Methods:
In a prospective study, the authors evaluated 15 frontalis sling suspension surgeries using palmaris longus tendon in 14 consecutive children with congenital ptosis. The method of harvesting the palmaris longus tendon is described in detail.
Results:
The mean age of the patients was 4.7 years (range, 2 to 7 years). At a mean follow-up of 30 months (range, 20 to 40 months), all ptotic eyelids were successfully corrected with good final lid position. No recurrence of ptosis was encountered. In one eye, knot slippage of the sling was related to upper eyelid trauma, which was readily repaired. Otherwise, no exposure keratitis, wound infection, eyelid contour abnormality, or ptosis overcorrection occurred. There were no complications associated with the palmaris longus tendon donor site.
Conclusion:
Frontalis suspension with autogenous palmaris longus tendon appears to be an effective treatment for congenital ptosis with poor levator function in children. Its use as an alternative material to fascia lata for sling surgery in children can be considered.
