[A study of innervation of musculus temporalis and its clinical application].
OBJECTIVE
To study the innervation of the musculus temporalis and improve the successful rate of the operation for paralytic eyelid ectropion.


METHODS
Anatomic dissection was performed in 12 fresh cadavers.


RESULTS
The data show that the distance between the outer canthus and the crus helicis is 8.733 +/- 1.311 cm. The deep temporal nerve spread radially to the edge of musculus temporalis at 3.852 +/- 0.353 cm and 6.317 +/- 0.330 cm at a 60-degree angle to the horizontal line. The rami of the deep temporal nerve rise at a 60-degree angle to the horizontal line in 3 parts from the outer canthus to the crus helicis.


CONCLUSIONS
In transferring the temporal muscle to treat paralytic ectropion, it is safe to make incisions at the middle one-third between the outer canthus and the crus helicis. The discovery has been used to treat 32 patients with eyelid ectropion of facial palsy, among whom 30(93.8%) got good results.
