The nonsurgical elementary rhinoplasty (NOSER) technique is performed in five steps using cannulas, a high G prime hyaluronic acid, and two injection entry points. The areas to be treated and the specific quantity of filler to be used are based on the assessment. Steps 1 to 3 are for the tip's projection, support and lift, and step 4 is for filling the radix area and straightening the dorsum. All five steps are done in small aliquots in the central area, at the deep plane. This technique could be a good and highly reproducible alternative for upgrading the nose contour.
However, delays beyond 48 h increase the likelihood of irreversible ischemia 玻尿酸隆鼻 and tissue necrosis, particularly in deeper skin layers. Although HSE can resolve embolic occlusion and alleviate ischemic damage, it cannot repair necrotic tissue. Comparison of prognostic outcomes and adverse events between two nitrate‐based treatment groups for nasal vascular compromise.
In Group 1 (“Filler + BTX”), subjects received BTX on the first treatment day and in Group 3 (“Threads + Filler + BTX”), 2 weeks after threads administration. Threads were inserted from the nasal tip through a puncture site made by an 18 G needle 2 mm below the nasal tip. Each thread was inserted and covered the length twice between the nasion superiorly and the nasal crest inferiorly (Figure 1). It comprised five P (LA/CL) multidirectional barbed threads (USP 2/0, EP 3), each 120 mm in length.
The specific steps of the procedure will then depend on the method chosen. In the immediate post-procedure period, light local pain and ecchymosis in the entry point is expected. The evaluation starts by analyzing the position of the nose in relation to each third of the face. When dividing the face into thirds latitudinally, the ideal nose should be localized in the middle third of the face and extend from the glabella to the subnasal region (Figure 3). The muscular part consists of the nasal transverse, nasal wing lifter, lip and nose lifter, and procerus and orbicularis oculi muscles. For both groups 1 and 2, 4 IU of BTX (Allergan) were injected at the lower edge of the columella to reduce the activity of the depressor septi.
Between May 2018 and July 2023, 41 female patients (mean age 36.2 years, range 25–46 years) who presented within 72 h following nasal ischemia from HA filler injections were enrolled in this retrospective study (Table 1). Patient demographics, clinical history, injection sites, symptoms, treatments, and outcomes were thoroughly reviewed using previously collected, fully de‐identified medical records, involving no additional risk or interventions. Consequently, this study was exempt from formal institutional review board oversight and complied with the Declaration of Helsinki ethical standards. All patients received HA injections externally at various clinics, predominantly involving the nasal dorsum, nasal tip, nasal ala, and columella.
In others, a single larger artery can be identified crossing the midline. Either direct surgical approach or hyaluronidase injection first seems to be a viable option with the total absence of post-operative complications. When direct surgery is preferred, it could be demanding and customized informed consent should be released to the patients prior to surgery. Hyaluronic acid (HA) fillers are among the most commonly used facial aesthetic treatments worldwide.1, 2 However, the face is a complex, dynamic structure and not all fillers are suitable for all areas. Instead, the product used should be tailored to the area being treated, based on a variety of factors, not least its rheologic and physicochemical properties.
In 35 patients, additional HA infiltration had to be performed after 2 weeks. Nonsurgical rhinoplasty using fillers, particularly HA, is generally safe with a low risk of severe complications. Awareness and prompt management of potential complications are crucial for practitioners.
This article was conducted with an aim to provide evidence regarding the techniques and complications of hyaluronic acid nasal injections to guide clinicians in evidence-based practice. Rhinoplasty is a prominent procedure in facial aesthetics, but extended surgical downtime remains its significant limitation. Nonsurgical rhinoplasty has gained popularity as an alternative, offering significant aesthetic improvements with minimal downtime.
Skin quality improvement and balanced anti-aging treatments often travel best across cultures because they focus on health, freshness, and proportion. Get a personalized treatment plan, transparent pricing, and full support from our international medical team. Still, some broad patterns appear repeatedly in academic literature, clinical reviews, and international procedure trends. Results typically last between months depending on the type of filler used and your body's metabolism.
We apply topical numbing cream for 15 minutes before the injections, so you feel pressure but minimal pain. I select the filler based on what area of the nose we are treating and how long you want the results to last. This is when a blood vessel becomes blocked, causing mottling or ulceration of tissue. If the blood vessel supplies the eye or brain, it may lead to blindness or stroke. For 2–3 days after the procedure, a person needs to avoid manipulating the nose and engaging in vigorous activity. Also, depending on the location of the injections, they may have to avoid wearing eyeglasses or sunglasses for a while to avoid creating an indentation.
Practitioners should be well-trained in both methods to tailor their approach to individual patient needs and specific anatomical considerations. In translating the above evidence into practice, we recommend a region-tailored approach that balances vascular risk, plane selection, and the need for precision. In the forehead/temple (supraorbital/supratrochlear territory), a cannula in deep, gliding planes with micro-aliquots is preferred; ultrasound is advisable near sentinel vessels. For the periorbital/tear trough, favor a 25–27 G cannula in a pre-periosteal or deep sub-orbicularis plane, avoiding boluses and confirming placement with ultrasound when available.
Liquid rhinoplasty, a form of non-surgical nose job, involves using dermal fillers for minor corrections and adjustments to the nasal structure. It’s an ideal option for those seeking cosmetic surgery without the invasiveness of a traditional rhinoplasty procedure. Current alternatives to cosmetic nasal reshaping are invasive and limited to endonasal and open rhinoplasty. Both require general anaesthesia, a prolonged postoperative recovery time, significant cost and the risk of dissatisfaction with the aesthetic and/or functional outcome. This chapter outlines the concepts behind hyaluronic acid injection rhinoplasty—a non-surgical ‘office-based’ alternative to improve contour and internal valve deficiencies, tip projection/rotation, columellar retraction and dorsal irregularities. Additionally, this procedure can make the nostrils appear slimmer as the tip of the nose is lifted.
Identify key challenges—spanning ethical concerns, regulatory gaps, and technological limitations—that hinder responsible AI deployment. Propose actionable strategies to balance innovation with human‐centric care, emphasizing transparency, inclusivity, and interdisciplinary collaboration. Artificial Intelligence (AI) is transforming healthcare by enhancing diagnostics, treatment personalization, and operational efficiency. In aesthetic medicine—a field blending medical expertise with artistic judgment—AI is increasingly being used to improve precision, optimize treatment outcomes, and personalize patient care. However, its integration presents both opportunities and ethical challenges, necessitating a critical evaluation of its role in this evolving field.
The duration of results varies based on factors like filler type and individual metabolism. Regular touch-up treatments may be needed to maintain desired outcomes. Non-surgical rhinoplasty typically uses local anesthesia or numbing cream to ensure minimal discomfort. Some patients may experience mild pain, but it is generally well-tolerated. Highly experienced practitioners who focus on cosmetic procedures often charge more due to their extensive training and skills.
