Abstract

Tissue engineering offers a solution to the shortage of materials for cartilage reconstruction surgery by providing various potential biomaterial scaffolds. Tissue engineering utilizes biological or synthetic biomaterials as a scaffold for the host cells to repopulate and regenerate the tissue. The natural biomaterials such collagen and chondroitin imitates native cartilage matrix composition. Genipin as one of natural crosslinkers was added to improve the matrix biomechanical properties. This study was done to investigate biocomposition of blended collagen type 1, collagen type 2, chondroitin sulphate (Col1-Col2-CS) and genipin for its cytotoxicity using human umbilical mesenchymal stem cells (hUCMSCs), surface morphology, and biochemical composition. Genipin-crosslinked collagen-chondroitin biocomposite showed a homogeneous shape while uncrosslinked biocomposite had rough surface and fibrillar folds size. Spectroscopy demonstrated both biocomposites had similar peak resemble to no alternation of the biocomposition by crosslinking. Both types of biocomposites were biocompatible and had no toxic effects, as compared to the cell colony only (p value = 0.26). The conclusion are blended composite of collagen chondroitin crosslinked with genipin had generated a fine microstructure scaffold with smaller pore size, had similar biomolecular component spectrum absorption, and no exhibition of residual toxicity.

Abstract

Latar belakang: Nasal bifida dan supernumerary nostril merupakan kelainan hidung  kongenital yang sangat jarang.  Nasal bifida disebut juga hidung ganda atau celah hidung, mempunyai manifestasi sangatberagam mulai dari lekukan minimal pada puncak hidung hingga celah maksila. Supernumerary  nostrilmerupakan bagian dari kelainan duplikasi hidung. Tujuan: Sebagai ilustrasi kepada ahli THT-KL mengenaikasus kelainan hidung kongenital yang jarang ditemukan. Kasus: Dilaporkan tiga kasus anak dengankelainan hidung kongenital selama bulan Agustus-Desember 2012. Satu kasus dengan  nasal bifida, satukasus dengan nasal bifida disertai atresia koana, dan satu kasus dengan triple nostril. Penatalaksanaan:Pada kasus nasal bifida dilakukan rekonstruksi hidung menggunakan  tandur dermis dan pada kasustriple nostril dilakukan fistulektomi dan rekonstruksi alae. Kesimpulan: Nasal bifida dan triple nostrilmerupakan kelainan hidung kongenital yang jarang ditemukan. Kelainan ini membutuhkan rekonstruksiyang optimal. Indikasi waktu dari operasi pada kasus kelainan hidung kongenital ini berdasarkan ukuranhidung menyerupai ukuran dewasa dan perkembangan sosial anak. Kata kunci: kelainan hidung kongenital, nasal bifida, supernumerary nostril, duplikasi hidungABSTRACT Background: Bifid nose  and supernumerary nostril are  rare nasal congenital anomalies. The appearance of bifid nose, also called double nose or cleft nose, varies from a simple groove at thenasal apex to a maxillary cleft.  Supernumerary nostril is a kind of nasal duplication. Purpose: Thiscase report is to forewarn general practitioners and ENT specialist about these rare nasal congenitalanomaly cases. Case: Reported three cases with congenital nasal anomaly, one case with bifid nose, onecase with bifid nose and choanal atresia, and one case with triple nostril. Management: The cases withbifid nose underwent nasal reconstruction using dermal graft and the case with triple nostril underwentfistulectomy and alae reconstruction. Conclusion: Bifid nose and triple nostril are rare nasal congenitalanomaly that need optimal reconstruction. Indication for the time of the operation for cases of congenitalnasal deformities is based on the size approaching the adult size and on the child’s social development. Keywords: congenital nasal anomaly, bifid nose, supernumerary nostril, nasal duplication
