| Abstract: | Paraseptal cartilages (PCs) have been the subject of controversy, in that some authors believe them to be absent or rarely present, while others have described them to exist at predictable locations in adult human tissue specimens. This study seeks to determine the presence or absence of PCs in humans and describe their morphology and size. Nasal septal tissue from 19 adults and 1 child were paraffin embedded, coronally sectioned, placed on slides, and stained for microscopic observation. For all specimens, PCs were identified and lengths were calculated. Selected PCs were also digitized in order to calculate volume. Results demonstrated that PCs were present in all 20 tissue specimens and assumed a common morphology. In each, PCs were found to begin as hyaline cartilage lobes that extend projections in a superolateral direction as an anteroposterior course is followed. The projections were found to rotate inferiorly until each PC was found to assume a position that extended below the nasal septum. Length measures in adults ranged from 8,725 to 19,000 μm (x = 14,188.9 μm) and volumes ranged from 7.7 to 24.2 (x = 13.2) × 10-3 ml. A quantitative comparison to foetal data from a previous study suggests prenatal and/or postnatal growth of PCs. Results from this study support the presence of PCs in adult humans as well as prenatal/postnatal growth of PCs. [ABSTRACT FROM AUTHOR] |
