[Applied anatomy on musclebone flap of hyoideumomohyoid to renovate vocal fold].
OBJECTIVE
In order to provide anatomical basis for renovating vocal fold with muscle-bone flap of hyoideum-omohyoid.


METHODS
It was measured that the anatomical structure correlative with superior belly of hyoideum-omohyoid, artery, vein and nerve of the muscle and vocal fold morphosis by 26(52 sides) cephalocevical sample dissection.


RESULTS
It was observed that the muscle is 74.8 mm in length, 8.4 mm in width of starting part, 9.6 mm in width of middle part, 4.4 mm in width of tendon part. Its blood supply are mainly from cricothyriod artery (51.9%) and superior laryngeal artery (25.0%) with an arterial trunk of 9.8 mm in length and 0.7 mm in diameter. The venous trunk is 17.4 mm in length and 1.1 mm in diameter. The muscle is innervated by the sub-broaches arising from hypoglossal nerve ansa, the trunk is 19.6 mm in length and 0.6 mm in diameter.


CONCLUSIONS
It is possible that musclebone flap of hyoideumomohyoid to renovate vocal fold according to the study of the muscle morphology characteristic.
