BACKGROUND: Lips are central to facial aesthetics, influencing overall balance and harmony. Ultrasound has become a key tool for assessing lip musculature and neurovascular structures, particularly in aesthetic filler injections. By enhancing precision and safety, ultrasound is valuable in procedures addressing age-related lip changes, yet standardized scanning protocols remain underexplored. AIMS: This review examined lip anatomy, summarized ultrasound applications in aesthetic procedures, introduced a structured scanning protocol, and highlighted its role in guiding filler injections. METHODS: A systematic search of PubMed, Scopus, Embase, and Web of Science was conducted up to August 1, 2024, using keywords related to ultrasound and lip anatomy. Studies involving human subjects or cadavers using ultrasound for lip assessment and injection guidance were included, whereas nonhuman studies, alternative imaging methods, and research unrelated to the lip region were excluded. Six studies met the criteria. RESULTS: Ultrasound improves precision in lip injections by identifying key structures, including the superior and inferior labial arteries and the orbicularis oris muscle, reducing vascular risks. A structured scanning approach enhances procedural safety and efficacy. CONCLUSIONS: Ultrasound is a valuable tool in aesthetic lip procedures, improving accuracy and minimizing complications. Further research is needed to refine protocols and establish ultrasound as a standard practice in lip augmentation.

The paraspinal muscles of the cervical, thoracic, and lumbar spine are important pain generators because muscle strains or myofascial pain syndrome caused by trigger points are common during clinical practice. Ultrasonography is the most convenient imaging tool for evaluating these muscles due to its advantages, such as providing good delineation of soft tissues, easy accessibility, and zero radiation. Additionally, ultrasound can serve as a useful guiding tool for paraspinal muscle intervention to prevent inadvertent injuries to vital axial neurovascular structures. This pictorial essay presents ultrasound scanning protocols for the paraspinal and other associated muscles as well as a discussion of their clinical relevance. Axial magnetic resonance imaging has also been used to elucidate reciprocal anatomy. In conclusion, ultrasound imaging proves to be a valuable tool that facilitates the differentiation of individual paraspinal muscles. This capability significantly enhances the precision of interventions designed to address myofascial pain syndrome.

Ischiofemoral impingement syndrome is a neglected cause of posterior hip pain which is derived from narrowing of the space between the lateral aspect of the ischium and the medial aspect of the lesser trochanter. Its diagnosis is challenging and requires the combination of physical tests and imaging studies. In the present narrative review, we found that femoral anteversion predisposes patients to the narrowing of the ischiofemoral space and subsequent quadratus femoris muscle injury. Magnetic resonance imaging serves as the gold-standard diagnostic tool, which facilities the quantification of the ischiofemoral distance and the recognition of edema/fat infiltration/tearing of the quadratus femoris muscle. Ultrasound is useful for scrutinizing the integrity of deep gluteal muscles, and its capability to measure the ischiofemoral space is comparable to that of magnetic resonance. Various injection regimens can be applied to treat ischiofemoral impingement syndrome under ultrasound guidance and they appear to be safe and effective. Finally, more randomized controlled trials are needed to build solid bases of evidence on ultrasound-guided interventions in the management of ischiofemoral impingement syndrome.

The facial and submental regions are supplied by complicated neurovascular networks; therefore, facial aesthetic injections may be associated with serious adverse events such as skin necrosis and blindness. Pre-injection localization of neurovascular structures using high-resolution ultrasound can theoretically prevent unexpected complications. Therefore, a systematic protocol that focuses on these facial neurovascular structures is warranted. In this pictorial essay, we discuss the sonoanatomy of facial and submental neurovascular structures and its relevance to aesthetic injections. Moreover, we have highlighted the mechanisms underlying potential neurovascular injuries during aesthetic injections.
