Abstract
Injection rhinoplasty offers an attractive, reversible alternative to surgery. Here
we assessed outcome, longevity of benefits, adverse effects, and patient assessment
of injection rhinoplasty, using degradable synthetic fillers. Forty-six patients who
underwent injection rhinoplasty using degradable fillers over the past 3 years were
assessed (calcium hydroxyapatite: 26 patients, hyaluronic acid: 20 patients). Comparison
of pre- and postoperative images indicated realistically achievable treatment results.
Patient satisfaction was assessed using a 5-point questionnaire at 3 weeks and 9 months
posttreatment. Forty-six patients (88 areas) were treated. At 3 weeks posttreatment,
85% of patients were satisfied with treatment results. At 9 months or later posttreatment,
87% of patients were very/completely satisfied with treatment results, regardless
of filler used. Treatment longevity varied between 6 and 30 months (mean: 13.5 months).
Positive evaluation was mainly due to accurate prediction of achievable results to
meet patient expectations. There were one moderate and two severe complications, all
following calcium hydroxyapatite treatment. Two resolved completely following treatment
and one patient was lost to follow-up. This resulted in subsequent exclusive use of
hyaluronic acid filler. Injectable biodegradable fillers are effective for correction
of minor nasal deformities or irregularities. Attention must be given to injection
technique and adverse effect management.
