Ultrasound assessment of the nose vasculature: A review of the common method of non-surgical filler-based rhinoplasty.

BACKGROUND: With the increasing use of dermal injectable fillers in aesthetic medicine, the popularity of non-surgical filler-based rhinoplasty (NSR) is also growing. While performing this procedure might result in certain vascular complications, injecting deep into the midline of the nose is commonly considered the safest method for blind primary NSR. AIMS: In this study, we challenged the common NSR method with a Doppler ultrasound study of the nose. PATIENTS/METHODS: The vascular pattern of the common zones of the NSR procedure (radix and nasal tip) of 21 Iranian women were investigated by using a 14 MHz Doppler handheld ultrasound device (Silarious L14PS). Participants had never undergone any procedure on their nose. We focused on the depth of midline vessels in the radix and nasal tip. The radix was studied sagittally and horizontally, and the nasal tip was examined axially by ultrasound. RESULTS: In the radix of eight cases (38%), at least one vessel was observed at midline, and all were superficial. In the nose tip of 18 cases (86%), at least one vessel was observed at midline, and 9 out of these 18 vessels (50%) were deep. As a result, conducting NSR by the common method in our study population was relatively safe in the radix, but there was an increased likelihood of vascular events in the tip. CONCLUSION: Our research results show that while the common method of the NSR may carry a high risk of vascular events, the safety of this procedure could be enhanced by using ultrasound for planning and conducting a tailored treatment.

Introducing an esthetic treatment of malocclusion: Ultrasound-assisted augmentation of premaxilla with injectable hyaluronic acid filler.

With advances in the ultrasound-assisted esthetic procedures, filler injection can successfully be used for cosmetic correction of face structural imperfections. Here, we present a new filler injection method by targeting two anatomic landmarks which effectively improved the appearance of a mandibular prognathism case who was a maxillofacial cosmetic surgery candidate.

Ultrasound-assisted management of filler-related complications: Report of a successful treatment of delayed-onset nodules related to polycaprolactone-based filler.

A 60-year-old woman underwent polycaprolactone-based filler injection in her midface. Four months later, she developed progressive swelling of midface after a self-limiting viral gastroenteritis. The diagnosis was "delayed-onset immune-mediated nodule formation triggered by a virus." Ultrasonography enabled us to efficiently treat her with a tailored intralesional corticosteroid injection method.
