![]() This rare disorder needs the strength of numbers to answer these questions, which is the purpose of the international registry of CPSS (IRCPSS). In addition, the etiology and pathophysiology of CPSS are both unknowns. Which patients will benefit from shunt closure remains to be clarified, as does the timing and method of closure. CPSS are characterized by multiple signs and symptoms, often masquerading as other conditions, progressing over time if the shunt remains patent. doi: 10.1186/s13022-8.īACKGROUND: Congenital portosystemic shunts (CPSS) are rare vascular malformations associated with the risk of life-threatening systemic conditions, which remain underdiagnosed and often are identified after considerable diagnostic delay. Also, the nasofrontal angle in men and the pyramidal angle in women increased significantly.ĬONCLUSION: These results suggest that the aging process leads to drooping of the nasal tip, thickened nasal skin and soft tissue, and resorption of the nasal bone, providing a reference for rhinoplasty in the elderly. With regard to nasal bone changes, the bone length decreased significantly in women, and the bone thickness decreased significantly in either sex. ![]() The nasal length and nasofrontal angle showed significant age-related increases in men, as well as the decrease of nasal tip angle and the increase of pyramidal angle were significant in women. Besides, the increase of the nasal depth and the decrease of nasolabial angle were significant in either sex. RESULTS: With regard to soft tissue changes, the nasal SSTE thickness at rhinion, supratip, and nasal tip significantly increased with aging in either sex. The measurements of nasal soft tissue and bone on CT were performed by software Osirix 9.0. The study population was divided into two groups according to age and sex: young group aged 20 to 35 years, and old group aged 65 to 80 years. METHODS: The CT images of two hundred Asian patients were included. This study aimed to determine the evolution of nasal soft tissue and bone in aging noses utilizing computed tomography (CT). ![]() ![]() Online ahead of print.īACKGROUND: Morphological and anatomical changes of the aging nose affect the surgical strategy of rhinoplasty in the elderly, but age-related changes in noses have yet to be fully characterized.
