Use of a Surgical Microscope for Subperichondrial-Subperiosteal Dissection in Preservation Rhinoplasty: Ergonomic Considerations

Overview

Preservation of anatomical components in rhinoplasty has become more popular. Lifting the skin covering in a continuous plane beneath the membranes over cartilage and bone preserves soft tissue, vessels, nerves and lymphatics, which the authors state may lead to faster healing with less swelling and scarring. However, the technique requires a learning phase and is usually done under magnifying loupes, making it slow and demanding.

Sections of note

• Technique proposal; the abstract reports no patient numbers, no outcomes and no follow up.
• Continuous dissection beneath the perichondrium and periosteum preserves soft tissue, vessels, nerves and lymphatics.
• The authors state this may result in faster healing with less swelling and scarring.
• The dissection is described as time consuming and burdensome, especially in revision cases.
• The authors raise the risk of musculoskeletal discomfort and injury to the surgeon.
• They propose using a surgical microscope for the dissection.
• A microscope is said to give clear visualization and allow precise, delicate manipulation.
• It is also said to let surgeons keep an ideal posture with neutral joint positioning, reducing physical strain.

What it means for a patient

• The deep dissection plane is what preserves the nerves and vessels in the nasal covering, which is the stated reason for less swelling.
• The proposal concerns how the surgeon sees and reaches that plane, not what is done to the nose.
• Claims about faster healing and reduced swelling are stated as possibilities, with no supporting data.
• Surgeon posture and injury risk are the article's second concern, which is about the surgeon rather than the patient.

Why this paper matters

Preservation techniques demand a more meticulous dissection than conventional rhinoplasty, and that burden falls on the surgeon's hands, eyes and back. This article proposes an equipment answer. Whether a microscope improves the dissection or the result has not been measured.

Terms

• Subperichondrial dissection: separating tissue beneath the membrane covering cartilage.
• Subperiosteal dissection: separating tissue beneath the membrane covering bone.
• Soft tissue envelope: the skin, fat and muscle covering the nasal framework.
• Surgical loupes: magnifying lenses worn on glasses.
• Ergonomics: the design of work conditions to reduce physical strain and injury.
• Lymphatics: the vessels that drain tissue fluid, whose disruption increases swelling.
