Adjuvant Therapy for Revision Rhinoplasty of Contracted Nose Using Polydeoxyribonucleotide and Invasive Bipolar Radiofrequency

Overview

A contracted nose is one where scarring has tightened the skin so it will not stretch to cover a rebuilt framework. Operating on it risks closing under tension. This study tested whether treating the skin before and after surgery with an injectable and a heat-based device makes the revision workable.

Sections of note

• 30 patients received 16 sessions in total: 8 preoperative and 8 postoperative, at 1-week intervals.
• Each session combined intralesional injection of polydeoxyribonucleotide with invasive pulsed bipolar radiofrequency delivered through microneedle electrodes.
• One week after the final pretreatment, the skin of the contracted noses was sufficiently softened and skin mobility notably improved in all patients.
• During revision rhinoplasty and septoplasty, the skin was adequately released to cover the tip without tension in each patient.
• The 8 postoperative sessions produced marked improvement in persistent tip dimpling, contracture, septal deviation, and warping.
• The authors report no major side effects.
• The abstract states no follow-up duration, no comparison group, and no numeric outcome scores.

What it means for a patient

• The skin envelope, not just the cartilage framework, can be the limiting factor in revising a badly contracted nose.
• Treatment is spread over about 16 weeks of weekly sessions around the operation.
• Limits: 30 patients, no control group, no randomization, no objective measurement of skin softening, and outcomes described in words rather than numbers.
• Two treatments were given together, so their individual contributions cannot be separated.

Why this paper matters

Contracted nose is one of the hardest revision problems, particularly after implant complications, and skin that will not stretch limits what surgery can achieve. Preparing the skin medically before operating is a different line of attack. Without a control group the reported improvement cannot be attributed to the adjuvant therapy.

Terms

• Contracted nose: A nose whose skin has scarred and tightened, shortening and distorting it.
• Polydeoxyribonucleotide: An injectable DNA-derived compound used to promote tissue repair.
• Radiofrequency: Energy delivered as controlled heat to remodel tissue.
• Intralesional: Injected directly into the affected tissue.
• Adjuvant therapy: Treatment given alongside the main procedure to improve its result.
