  • A newly defined conchal floor arterial flap for Auricular reconstruction.
    Plastic and reconstructive surgery, 2002
    Co-Authors: Chul Park
    Abstract:

    A conchal floor composite flap pedicled by skin of the helical crus has been well described in the literature. Here the flap is elevated based on the supply by an upper Auricular branch of the superficial temporal Artery. In this article, a newly defined conchal floor arterial flap is proposed. The flap is based on the main stem of the Posterior Auricular Artery and its venae comitantes. Two types of conchal floor arterial flaps were elevated: a proximally based chondral arterial flap and a distally based chondrocutaneous arterial flap. The proximally based flap was used for earlobe reconstruction, whereas the distally based flap was useful in the reconstruction of the upper auricle. Nine congenital Auricular malformations were successfully corrected with this newly defined conchal floor flap procedure. This type of flap is easier to elevate, more reliable, and more versatile than the one currently in use.

  • Arterial supply of the anterior ear.
    Plastic and reconstructive surgery, 1992
    Co-Authors: Chul Park, William C. Lineaweaver, Thomas O. Rumly, Harry J. Buncke
    Abstract:

    Twenty cadaver auricles were injected with a latex solution to define the arterial supply of the anteroAuricular surface. Two arterial networks exist, the network of the triangular fossa-scapha and the network of the concha. Both eventually communicate on the anthelix. The triangular fossa-scapha network originates from one subbranch of the upper Auricular branch of the superficial temporal Artery and from branches of the Posterior Auricular Artery that come through the earlobe and triangular fossa and over the helical margin. The conchal network is provided by two to four perforators that come from the Posterior Auricular Artery, piercing the conchal floor. Auricular branches of the superficial temporal Artery in the preAuricular region and their communications with the Posterior Auricular Artery also were confirmed. We believe that a greater understanding of the detailed arterial anatomy in this area allows one to develop safely a variety of surgical techniques for reconstruction of the ear.

  • A single-stage two-flap method of total ear reconstruction
    Plastic and reconstructive surgery, 1991
    Co-Authors: Chul Park, Keuk Shun Shin, Taik Jong Lee, Yang Woo Kim
    Abstract:

    A single-stage two-flap method of total ear reconstruction in congenital microtia is reported. This method was derived from the one-stage reconstruction described by Song and Song. Two flaps defined by vascular basis were elevated on the mastoid area: the superficial skin flap supplied mainly by subcutaneous pedicled arteriole perforators from the Posterior Auricular Artery and the deeper axial-pattern fascial flap including the Posterior Auricular Artery itself. The ear framework, exaggeratedly carved using autologous rib cartilage, could be inserted easily between the two flaps, simultaneously producing the auriculocephalic angle and the conchal wall. Intraoperative expansion of the skin flap and postoperative external ear molding also were performed to create aesthetically pleasing ears.

  • Anatomic Variation of the Superficial Temporal Artery and Posterior Auricular Artery in a Pediatric Moyamoya Disease Population.
    AJNR. American journal of neuroradiology, 2021
    Co-Authors: S Lee, S-k Kim, J H Phi
    Abstract:

    In certain cases of pediatric patients with Moyamoya disease undergoing encephaloduroarteriosynangiosis (EDAS) treatment, the Posterior Auricular Artery can be used as an alternative when the parietal branch of the superficial temporal Artery is unavailable. In this study, anatomic variations of the superficial temporal and Posterior Auricular arteries in pediatric patients with Moyamoya disease and postoperative outcomes of Posterior Auricular Artery-EDAS are explored. Medical records of 572 patients with Moyamoya disease who underwent surgical procedures from 2007 to 2017 at the Seoul National University Children's Hospital were reviewed. Anatomic classifications of the superficial temporal and Posterior Auricular arteries were based on previous classifications. Postoperative hemodynamic changes of Posterior Auricular Artery-EDAS were analyzed using the Matsushima grade. Also, Karnofsky Performance Scale and mRS scores of Posterior Auricular Artery-EDAS cases were reviewed to identify postoperative clinical outcomes. Among 1144 hemispheres, 24 were considered Posterior Auricular Artery-EDAS candidates (2.1%). Of those, 10 hemispheres underwent Posterior Auricular Artery-EDAS (41.7%, in total hemispheres 0.9%). Comparing the Matsushima grades of the superficial temporal Artery-EDAS and Posterior Auricular Artery-EDAS groups showed similar postoperative revascularization. Postoperative Karnofsky Performance Scale and mRS scores of patients having undergone Posterior Auricular Artery-EDAS did not show deterioration. In approximately 2% of pediatric patients with Moyamoya disease for whom the superficial temporal Artery is unavailable as the EDAS donor, the Posterior Auricular Artery can be considered an alternative. On the basis of the results, the clinical outcome of Posterior Auricular Artery-EDAS was not inferior to that of superficial temporal Artery-EDAS. Hence, we suggest an in-depth consideration of the Posterior Auricular Artery as the donor Artery if the superficial temporal Artery parietal branch is unavailable. © 2021 by American Journal of Neuroradiology.

    Abstract:

    BACKGROUND AND PURPOSE: In certain cases of pediatric patients with Moyamoya disease undergoing encephaloduroarteriosynangiosis (EDAS) treatment, the Posterior Auricular Artery can be used as an alternative when the parietal branch of the superficial temporal Artery is unavailable. In this study, anatomic variations of the superficial temporal and Posterior Auricular arteries in pediatric patients with Moyamoya disease and postoperative outcomes of Posterior Auricular Artery-EDAS are explored. MATERIALS AND METHODS: Medical records of 572 patients with Moyamoya disease who underwent surgical procedures from 2007 to 2017 at the Seoul National University Children’s Hospital were reviewed. Anatomic classifications of the superficial temporal and Posterior Auricular arteries were based on previous classifications. Postoperative hemodynamic changes of Posterior Auricular Artery-EDAS were analyzed using the Matsushima grade. Also, Karnofsky Performance Scale and mRS scores of Posterior Auricular Artery-EDAS cases were reviewed to identify postoperative clinical outcomes. RESULTS: Among 1144 hemispheres, 24 were considered Posterior Auricular Artery-EDAS candidates (2.1%). Of those, 10 hemispheres underwent Posterior Auricular Artery-EDAS (41.7%, in total hemispheres 0.9%). Comparing the Matsushima grades of the superficial temporal Artery-EDAS and Posterior Auricular Artery-EDAS groups showed similar postoperative revascularization. Postoperative Karnofsky Performance Scale and mRS scores of patients having undergone Posterior Auricular Artery-EDAS did not show deterioration. CONCLUSIONS: In approximately 2% of pediatric patients with Moyamoya disease for whom the superficial temporal Artery is unavailable as the EDAS donor, the Posterior Auricular Artery can be considered an alternative. On the basis of the results, the clinical outcome of Posterior Auricular Artery-EDAS was not inferior to that of superficial temporal Artery-EDAS. Hence, we suggest an in-depth consideration of the Posterior Auricular Artery as the donor Artery if the superficial temporal Artery parietal branch is unavailable.

  • HCI (10) - Versatile Wearable Computer for Drivers
    Lecture Notes in Computer Science, 2011
    Co-Authors: Gyouhyung Kyung, Songyi Chae, Kyung Hyun Nam, Kyungmin Lee, Wanjae Shin
    Abstract:

    A versatile wearable computer for drivers (VWCD) was proposed that can extend in-vehicle multi-modal display spaces. In the first development phase, LEDs, mini video displays, earphones, and vibrators were included as visual, auditory and tactile displays, and were all attached to an eyeglass frame. One electrocardiographic electrode was attached to the VWCD to obtain the driver’s heart rate signal at the Posterior Auricular Artery, and a gyro sensor was used to track the driver’s head position. Finally, a Bluetooth device was included to enable communication between VWCD and its mobile phone platform.
