Resected parts of 15 patients septums crushed and the form of these materials were observed. Histologic examination was performed on 6 cadavers. Whole quadrangular cartilages excised; dorsal, caudal, basal and central portions sampled as in standart septorhinoplasty procedure, somewhat harvesting a cartilage graft. All were fixed and sliced in sagittal plane, longitudinally; stained with masson trichrome, examinated by a histologist under light microscope. Three of them were examinated by electron microscope but slices were transverse to the axis of cartilage strut or rod. Dorsum and columella posses a longitudinal direction of collagen organisation and strongly packed. Central and base portions have a more disorganised pattern and weaker. Base show collagen organisation perpendicular to palate. These data may be helpful for correction of problematic septum deformities. These lines may also be helpful in septoplasties and understanding the role of septum in maxillofacial development.trinfo:eu-repo/semantics/closedAccessSeptum; cartilage; tension lines; collagenArticle1627983WOS:000416763600004N/A
