Unveiling the Impact of Three-Dimensional Technology on Rhinoplasty: A Systematic Review and Meta-analysis

Overview

The authors investigated whether three dimensional technology improves preoperative assessment for rhinoplasty. They searched Embase, MEDLINE and Web of Science, with surgeon and patient satisfaction as the primary outcome and nasal function, cost efficiency, reoperation rate, precision and surgical time as secondary outcomes.

Sections of note

• Design: systematic review and meta-analysis. 12 studies covering 595 patients.
• Surgeons reported higher satisfaction with three dimensional approaches, citing precision and postoperative results.
• Patients reported satisfaction from better understanding of the procedure and the ability to discuss planning and participate in postoperative design.
• Surgeon satisfaction favored three dimensional methods: mean difference minus 0.13, 95 percent confidence interval minus 0.20 to minus 0.06, p equal to 0.0002, particularly in revision cases.
• Precision was higher with three dimensional than with two dimensional approaches.
• Three dimensional technology was more expensive and not cost efficient.
• Reoperation rate did not differ significantly: odds ratio 0.16, p equal to 0.09.
• Surgical time did not differ, and postoperative nasal function results were inconsistent.

What it means for a patient

• The clearest benefit was to the consultation: patients understood the plan better and could take part in it.
• Reoperation rates were not significantly lower, so better planning did not translate into fewer return operations in this pooled data.
• The measured surgeon satisfaction difference was small, at 0.13 points.
• Limits: 12 studies with 595 patients, heterogeneous designs, and breathing outcomes that pointed in different directions across studies.

Why this paper matters

Three dimensional imaging and simulation are marketed as improving rhinoplasty outcomes, and this review tests that against the evidence. It finds a real gain in planning and communication but not in the outcomes that would justify the cost. Whether improved communication reduces dissatisfaction is not measured.

Terms

• Three-dimensional technology: imaging or simulation that captures the face in depth rather than as a flat photograph.
• Preoperative evaluation: assessment performed before surgery to plan the operation.
• Meta-analysis: statistical pooling of results from multiple studies.
• Cost-efficiency: whether the benefit gained justifies the additional cost.
• Reoperation rate: the proportion of patients needing a further operation.
• Odds ratio: how much more likely an outcome is in one group than another.
