The popularity of dermal filler treatments is increasing in the Nordic countries. In Finland, legislation does not mandate healthcare training for those performing dermal filler treatments, potentially leading to increased complications. This registry-based study aimed to characterize complaints on dermal filler treatments received by Finnish Authorities, using data from (1) Finnish Safety and Chemicals Agency (TUKES), (2) the National Supervisory Authority for Welfare and Health (Valvira), (3) the Finnish Competition and Consumer Authority (KKV), and (4) Regional State Administrative Agency (AVI). From January 1, 2017, to December 31, 2024, 19 complaints were received by KKV, unsuccessful lip filler treatments being the most common issue (59%). No life-threatening complications were reported. Most cases (56%) occurred in beauty salons, with treatments primarily performed by beauty salon employees (44%), followed by registered nurses (24%), and only 8% by medical doctors. Notably, 72% of the complications occurred in the last 3 years. The study underscores the need for regulatory oversight and advanced medical expertise in administering dermal filler treatments due to the increasing complications and the involvement of non-medical personnel. Complications may require immediate medical first aid and should be classified as procedures requiring advanced medical expertise.

Condylar process fractures are a common mandibular injury predominantly affecting males, with a male-to-female ratio of 3:1. This study examines outcomes in patients with mandibular condylar fractures treated either conservatively or surgically, comparing long-term subjective results. A total of 281 cases were reviewed (144 treated conservatively and 137 treated surgically), with symptoms and functional outcomes assessed through questionnaires. Surgical intervention was more common in complex cases (e.g. bilateral fractures or concurrent maxillofacial injuries), and the surgical treatment group had a higher proportion of male patients and trauma related to violence. Mandibular joint sounds (e.g. clicking and crepitation) were more frequent in patients treated conservatively, whereas pain both at rest and during movement was more common in women and those with interpersonal violence-related trauma. Multivariable analysis indicated the presence of concurrent fractures as a risk factor for joint sounds, and gender and trauma type influenced pain and symptom frequency. Despite these differences, both treatments achieved comparable success in maintaining stable occlusion and achieving painless jaw function. These findings suggest that both conservative and surgical treatments can be effective, although individual factors such as gender, trauma type and concurrent fractures may affect post-treatment symptomatology and choice of treatment.
