Summary

The return of eyelid function and facial expression in Patients with facial nerve affection is very important for quality of life. Eyelid dysfunction leads to drying and ulceration of cornea which may lead to permanent vision loss.

Facial paralysis is distinguished into two main groups according to the presence or absence of facial fibrillations at needle Electromyography. Recent paralysis, mainly lasting less than two years generally show these signs and are eligible for reactivation of facial nerve by anastomosing it to a donor one (early facial reanimation).

The masseteric nerve (motor branch of trigeminal nerve ) is a reliable donor nerve on early facial reanimation.

The deep temporal nerves are motor branches of trigeminal nerve which have some advantage over masseteric nerve as they are longer and reach the zygomatic and frontal branch of facial nerve and it can reach the eyelid and eyebrow to be used for direct neurotization and it supplies temporalis muscle which is an expandable muscle with little effect on mastication and it was reported that they can restore blinking.

So on this study we examine the advantages and disadvantages of both nerves to develop a protocol for use of both especially on eyelid reanimation and restoration of blinking on upper facial segment paresis

Conditions

  • Facial Paresis

Interventions

PROCEDURE

Deep temporal nerves

Surgical procedure: Group A Exploration on the affected side a facelift-type incision will be performed, and an anterior subcutaneous flap is then will be lifted for several centimetres. In the inferior zygomatic region, the plane of elevation is deepened into the sub-SMAS plane and a composite flap elevated for several centimetres. Following elevation in this plane, the distal facial nerve branches will be identified. The distal portion of the zygomatic nerve is usually located midway between the oral commissure and the helical root. and was confirmed by nerve stimulator. The deep temporal fascia and temporalis muscle will be incised along the temporal fusion line and will be reflected from the skull to expose the divisions of the deep temporal nerves and the longest branch was traced and prepared for anastomosis end to end with the zygomatic branch after confirming the eyelid supply.

PROCEDURE

massteric nerve

group B The same procedure as group A except tracing the masseteric nerve related to masseter muscle and anastomosis will be the same
