[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.
Conclusion:
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.
