천측두동맥의 임상해부학적 연구 = THE STUDY OF THE GLINICAL ANATOMY OF THE SUPERFICIAL TEMPORAL ARTERY

다국어 초록 (Multilingual Abstract)

The conspicuous advancement in the microvascular surgery is required more precise understanding of the anatomical knowledges.
In the past, the superficial temporal fascia was used for the one stage reconstruction of the traumatic ear defect of congenital microtia and facial deformities, as a pedicled flap.
As the microsurgical techniques advance, it became use for the reconstruction of the face or extremity deformities, as a free flap.
Recently as the anatomical research precisely, it became possible to use the vascularized clavarial bone flap by using the pedicled superficial temporal artery.
For the purpose of avoiding the risk of temporal branch of the facial nerve and extending the clinical application, authors dissected the 24 surfaces of the 12 Korean adult cadavers and obtained the following results:
1. If the superficial temporal siphon is released to lengthening of the vascular pedicle, it may increase the pedicle length up to 7.2mm(S.D. 7.8mm).
2. The vascular pattern of the superficial temporal arteries are classified according to Eustathianos classification.
The results were obtained as follows:
Type Ⅰ..........75%
Type Ⅱ..........17%
Type Ⅲ.......... 0%
Type Ⅳ.......... 8%
Type Ⅴ.......... 0%
3. The diameter of STA, STV, frontal branch of STA, parietal branch of STA, MTA, MTV and the lengths of MTA, MTV were as follows: Note table 1
4. In our study, we measured the distance between the superficial temporal artery(A) and the most posterior significant twig of the temporal branch of the facial nerve(B) and found it to vary between 0 and 8 mm. The mean figure was 2.6mm (S.D. 1.9mm).
5. We measured the distance between the most prominent bony landmark of the lateral supraorbital ridge(P) and the most posterior significant twig of the temporal branch of the facial nerve(T) and found it to vary between 12 and 45 mm. The mean figure was 29mm (S.D. 8 mm).
6. We measured the distance between the most prominent bony landmark of the lateral supraorbital ridge(P) and the frontal branch of the superficial temporal artery(S) and found it to vary between 15 and 60mm. The mean figure was 32.5mm(S.D. 6.9mm).
7. The mean square of the superficial temporal fascia flap measured about 13cm in length and 11cm in width and that of the deep temporal fascia flap measured 7 cm in length and 6.5 cm in width.
