The anatomical structure similarity research on auricular cartilage and nasal alar cartilage
Journal of clinical otorhinolaryngology head and neck surgery, 2015Co-Authors: Changyong Chen, Wenzhi Li, Binbin Li, Huan WangAbstract:OBJECTIVE: There are many scaffold materials of repairing nasal alar cartilage defects. Auricuiar cartilage was used extensively in terms of its abundant tissues, good elasticity, little donor-site malformation, good plasticity etc. The authors dissected auricular cartilage and nasal alar cartilage, measured cartilage's morphous data and found some similar territories with nasal alar cartilage in the structure of auricular cartilage. METHOD: An anatomical study was performed using 10 adult cadavers acquired through Plastic Surgery Hospital, Peking Union Medical College, Beijing, China. Seven male and three female cadav-ers were included in the study. Harvest 20 auricular cartilage specimens and 20 nasal alar cartilage specimens. Then, Computed Tomography Scan on the auricular cartilage and nasal alar cartilage were performed. The datas were imported into mimics and three-dimensional reconstructions of the auricular cartilage and nasal alar cartilage were carried on. RESULT: Parts of the auricular cartilage, such as conchal fossa, tragus, Intertragic Notch, and cymba of auricular concha, curs of helix and curs of helix, triangular fossa, are ana-tomically similar to nasal alar cartilage. CONCLUSION: This study reports the anatomy of auricular cartilage and nasal alar cartilage, found some territories in the auricular cartilage, such as conchal fossa, tragus, Intertragic Notch, and cymba of auricular concha, curs of helix and curs of helix, triangular fossa, are anatomically similar to nasal alar cartilage. This research provides the anatomical basis that auricular cartilage was used to repair the nasal cartilage defect.

anatomy of the Intertragic Notch of the auricle may protect the ear canal from fluids as a built in overflow spout at an appropriate position
Journal of International Advanced Otology, 2019Co-Authors: Amitava BiswasAbstract:: To observe the utility of the Intertragic Notch during rain showers, an anatomic replica of the human auricle was studied under an artificial shower system with a video recorder. During the shower, water trickled out through the Intertragic Notch naturally, avoiding the ear canal. This study finds one utility of the Intertragic Notch may be the prevention of water flowing into the ear canal during rain showers.

A chondropathy of the pinna in rabbits associated with rabbit haemorrhagic disease.
New Zealand Veterinary Journal, 1999Co-Authors: R. G. Clark, R. L. Sanson, J. W. Donaldson, M. X. J. Motha, G. J. E. KnowlesAbstract:Abstract Aims. To investigate the relationship between loss of parts of the pinna in rabbits and rabbit haemorrhagic disease (RHD). Methods. A case-control study design was employed. Rabbits with ear lesions were shot on farms in various locations in the South Island of New Zealand. For each case, an attempt was made to obtain a sex- and size-matched control rabbit from the same farm on the same day. Serum samples were collected immediately after shooting. The serum samples were tested for RHD titres from 1:10 to 1:640. A selection of affected ears was examined histologically. Odds ratios and their 95% confidence intervals were calculated to assess the relationship between ear loss and RHD antibody status at various serological cut-off levels. Results. Affected ears were characterised by firm cartilaginous nodules and ridges, folding of the ear or loss of pinna to form a Notch or complete loss of the outer pinna from about 0.5–2.0 cm above the Intertragic Notch. Histological changes in affected ears consi...

Relationship of the lobular branch of the great auricular nerve to the tympanoparotid fascia: Spatial anatomy for salvage during face and neck lift.
PLOS ONE, 2019Co-Authors: Anna JeonAbstract:To enable selection of a safer suspension site to use in face and neck lifting procedures, the spatial relationship between the tympanoparotid fascia and the great auricular nerve should be clarified. In this study, we aimed to elucidate the position of the tympanoparotid fascia and the pathway of the lobular branch of the great auricular nerve traversing the tympanoparotid fascia. Twenty hemifaces from non-preserved bequeathed Korean cadavers (5 males, 7 females; mean age, 77.0 years) were dissected to determine the great auricular nerve distribution close to the tympanoparotid fascia of clinical significance for face and neck lift procedures. We observed the tympanoparotid fascia in all specimens (20 hemifaces). The tympanoparotid fascia was located anteriorly between the tragus and Intertragic Notch. Regarding the spatial relationship between the tympanoparotid fascia and the great auricular nerve, we found the sensory nerve entering the tympanoparotid fascia in all specimens (100%), and the depth from the skin was approximately 4.5 mm; in 65% of the specimens, the lobular branch was found to run close to the tympanoparotid fascia before going into the earlobe. Provided with relatively safer surface mapping to access the tympanoparotid fascia free of the lobular branch of the great auricular nerve, surgeons may better protect the lobular branch by anchoring the SMAS-platysma flap and thread to the deeper superior and anterior portions of the expected tympanoparotid fascia.
