In open rhinoplasty, what does the technique of a marginal incision involve?

• A. Incision through the septum
• B. Incision follows the crura
• C. Incision along the nasal dorsum
• D. Incision at the columella

Answer: (B)

The marginal incision in open rhinoplasty is designed to follow the crura of the cartilage, which supports the tip of the nose. This incision allows for effective access to the underlying structures while preserving the contour and integrity of the nasal tip. By following the crura, the surgeon can adequately expose the nasal framework, allowing for precise modifications, such as reshaping or repositioning the cartilage to achieve the desired nasal aesthetic.

This technique is crucial because it minimizes trauma to surrounding tissues and optimizes healing, facilitating functional and cosmetic outcomes. It also provides the necessary access to address issues related to the nasal tip's width, projection, and overall shape.

In contrast, options mentioning incisions through the septum, along the nasal dorsum, or at the columella do not describe the specific morphological approach that the marginal incision entails during open rhinoplasty.
