Background: Surgical planning aims to restore coordinated eyelid function.
Although achieving voluntary eye closure is one of the primary goals, it cannot
guarantee return of involuntary blink. Restoration of the afferent pathway of the
reflex is a prerequisite, but successful coordination of the reflex components
and restoration of their time-related function are also required.
Methods: A retrospective review of 49 patients who underwent dynamic
procedures for blink restoration was performed. The patients were divided
into two groups. Group A (n = 42) included patients who underwent nerve
transfers: cross-facial nerve grafting and subsequent microcoaptations, mini-
hypoglossal nerve transfers, and direct orbicularis oculi neurotization.
Group B (n = 14) included patients who underwent eye sphincter substi-
tution techniques: pedicled frontalis, free platysma, mini-temporalis, and a
slip of free pectoralis minor transfers. Seven of the patients included in the
groups underwent both nerve and muscle transfer procedures. Objective
blink ratios were measured according to an established protocol by the senior
author (J.K.T.).
Results: Thirty patients were girls and 19 were boys. The age of the patients
ranged from 1 to 17 years, with a mean SD age of 7.5 3.2 years.
Denervation time ranged from 76 months to 15.25 years. Blink improvement
was noted in all of the patients. Blink scores and ratios were consistently
better in group A than in group B.
Conclusion: Dynamic procedures provide the functional potential on which
subsequent static procedures can be performed to aid blink return, taking
into account the future needs of the still growing patient. (Plast. Reconstr.

n patients with facial paralysis, except for re-
storing adequate voluntary eye closure in cases
of impaired eyelid function, one of the chal-
lenges has been restoration of the blink reflex.
The protective role of the blink reflex has been
described, and sequelae including corneal abra-
sions, exposure keratopathy, epiphora, and even
loss of vision can be avoided by achieving adequate
blink return.

Surgical planning in pediatric patients in-
cludes particular concerns distinct from the gen-
eral population. The requirements for the physi-
cally and psychologically developing child differ
from those of an adult with already developed
body image and psychological integrity. This study
presents a retrospective review of the pediatric
patients who underwent dynamic procedures aim-
ing at the restoration of the blink reflex per-
formed by the senior author (J.K.T.) as a part of
multistage facial reanimation procedures.
