Measurement of Age and Sex Related Changes in Nasal Tip Support Using Digital Newton Meter

Study Overview
=================
Brief Summary
-----------------
Background: It is predicted that the nasal tip support will decrease with aging due to weakening of cartilage and connective tissues. However, there is no consensus on the age at which this change began. It is quite difficult to evaluate the nasal tip support, while the ideal nasal tip support pressure is also not known. The aim of this study is to determine the nasal tip support pressure alterations in various age groups, by measuring nasal tip support with a Newton meter, according to age and gender. Methods: This prospective clinical study was conducted between January 2019 and April 2019 at a tertiary health facility. Nasal tip resistances in 4 different age groups, as 20-29, 30-39, 40-64 and 65 years and older, were measured with a digital Newton meter. A total number of 159 patients with a minimum of 36 patients in each age group were included in the study. Nasal tip resistance measurements were compared among nasal tip displacement distances of 2mm, 3mm and 4mm, according to age groups and gender.

Eligibility Criteria
-----------------
Inclusion Criteria: Four groups were formed as 20-29, 30-39, 40-64 and 65 years and older. A total of 159 patients with a minimum of 36 patients in each group were included in the study. Exclusion Criteria: Patients with a history of nasal trauma, previous nasal surgery (septoplasty, rhinoplasty, tumor surgery), severe deviation of the caudal septum, visible external nasal deviation, and systemic disease affecting the connective tissue were excluded from the study.
