  • Reconstruction of the Medial Canthus Using an Ipsilateral Paramedian Forehead Flap
    Archives of plastic surgery, 2013
    Co-Authors: Jin Hyung Kim, Jeong Min Kim, Jang Wan Park, Jae Ha Hwang, Kwang Seog Kim, Sam Yong Lee
    Abstract:

    Background The medial canthus is an important area in determining the impression of a person's facial appearance. It is composed of various structures, including canthal tendons, lacrimal canaliculi, conjunctiva, the tarsal plate, and skin tissues. Due to its complexity, medial canthal defect reconstruction has been a challenging procedure to perform. The contralateral paramedian forehead flap is usually used for large defects; however, the bulkiness of the Glabella and splitting at the distal end of the flap are factors that can reduce the rate of flap survival. We reconstructed medial canthal defects using ipsilateral paramedian forehead flaps, minimizing Glabellar bulkiness.

We reconstructed medial canthal defects using ipsilateral paramedian forehead flaps, minimizing Glabellar bulkiness.MethodsThis study included 10 patients who underwent medial canthal reconstruction using ipsilateral paramedian forehead flaps between 2010 and 2012. To avoid an acute curve of the pedicle, which can cause venous congestion, we attempted to make the arc of the pedicle rounder. Additionally, the pedicle was skeletonized from the nasal root to the Glabella to reduce the bulkiness.ResultsAll patients had basal cell carcinoma, and 3 of them had recurrent basal cell carcinoma. All of the flaps were successful without total or partial flap loss. Two patients developed venous congestion of the flap, which was healed using medicinal leeches. Four patients developed epiphora, and 2 patients developed telecanthus.ConclusionsLarge defects of the medial canthus can be successfully reconstructed using ipsilateral paramedian forehead flaps. In addition, any accompanying venous congestion can be healed using medicinal leeches

  • pengaruh penempatan isocenter terhadap kualitas citra dan informasi citra anatomi mri brain t1 fast spin echo potongan sagital di nasion dan Glabella
    JRI (Jurnal Radiografer Indonesia), 2019
    Co-Authors: Jackwin Surya D B, Sigit Wijokongko, Nanang Sulaksono
    Abstract:

    Background : Before conducting an MRI examination, there will be a positioning. One of the positions carried out is the placement of isocenter. Isocenter is a magnetic center point where each gradient will be centered at that midpoint (Brown and Semelka, 2010). Different isocenter placements can affect image quality (Caramanos et al, 2010). In practical experience in the Telogorejo Semarang SMC Hospital, the placement of the isocenter in the nation while in Dr. Soetomo and Premier Surabaya Hospital placed Isocenter in Glabella. To examine the effect of isocenter placement on image quality and MRI brain T1 fast spin echo anatomical image information in the nasion and Glabella and determine the optimal isocenter placement between the nasion and Glabella. Method : This type of research is quantitative with an experimental approach. This research was conducted at Telogorejo SMC Hospital Semarang. Data in the form of 16 MRI images of sagittal brain pieces of T1 Fast Spin Echo weighting on isocenter placement in the nasion and Glabella of 8 volunteers. Testing is done using the SPSS program where the image quality is analyzed by linear regression test, while for anatomical image information is analyzed by the Wilcoxon test. Result : The results of this study indicate that there is an effect of isocenter placement on the quality of MRI brain images of T1 fast spin echo sagittal pieces as seen from p value SNR (0.039) and CNR (0.010) <0.05 and from SNR percentage effect of 16.85% while CNR of 5, 8%. in addition to the influence, there are also differences in the anatomical image information of the MRI brain T1 fast spin echo sagittal section which is seen from the p value generated is 0.001 <0.05. Conclusion : Judging from the mean rank per anatomy, isocenter placement in the nasion is optimal in providing information on the mesencephalon, medulla oblongata, and cerebral subarachnoid space.
