Meridians

984
In surveying, meridians are vital reference lines to measure directions and establish accurate land orientations. Meridians run from the north to the south poles, providing a stable framework for angular measurements and mapping. Meridians are fundamental in survey design, with the primary types being astronomic, magnetic, and assumed meridians. Each type offers distinct benefits and limitations, selected based on the project's scale and precision needs.The astronomic meridian is aligned with...

Summary
This summary is machine-generated.

A new "rule of 11%" formula objectively estimates the breast meridian for breast reduction and mastopexy. This method improves surgical symmetry and patient satisfaction by providing predictable outcomes.

Area of Science:

  • Plastic Surgery
  • Surgical Anatomy
  • Medical Device Design

Background:

  • The breast meridian is crucial for breast reduction and mastopexy.
  • Traditional methods are subjective, leading to asymmetry.
  • A novel objective formula, the 'rule of 11%', is introduced.

Purpose of the Study:

  • To introduce and validate an objective formula for breast meridian estimation.
  • To improve symmetry and predictability in breast surgeries.
  • To enhance patient satisfaction through accurate nipple positioning.

Main Methods:

  • Collected chest wall width and underbust circumference data from 50 patients.
  • Calculated ideal nipple position using a 6:4 ratio of chest wall width.
  • Compared calculated position with 11% of underbust circumference; statistical analysis performed.

Main Results:

  • The ideal nipple position correlated with 11% of underbust circumference (mean ratio 0.111).
  • A strong positive correlation exists between chest wall width and underbust circumference.
  • Clinical application in four patients showed accurate positioning and high satisfaction.

Conclusions:

  • The 'rule of 11%' offers a reproducible, objective guideline for breast meridian design.
  • This bottom-up approach minimizes subjectivity, enhancing symmetry and outcomes.
  • Beneficial for novice surgeons, improving patient satisfaction and aesthetic results.
