Long-Term Side Effects of Soft Tissue Filler Injection / 대한피부과학회지

Background@#Injectable soft tissue fillers are important elements in facial rejuvenation as they provide volume restoration without significant inconvenience to the patient or substantial associated recovery time. Complications can be classified into immediate, delayed, or late adverse reactions. Most complications are temporary and common throughout the filler classes. @*Objective@#To describe the long-term side effects of fillers. @*Methods@#A retrospective study of 10 patients who experienced long-term side effects of soft tissue filler injections between 2007 and 2018 was conducted. A long-term reaction was defined as a complication that occurred 1 year after soft tissue filler injection at any facial site. @*Results@#Ten patients were included in the study. All the patients visited our department because of a palpable subcutaneous nodular lesion on their face. The mean duration from receiving the filler injection to the appearance of side effects was 4.3 years (range, 1∼12 years). Based on their clinicopathological features, complications were roughly classified into granulomatous inflammation (60.0%), non-inflammatory palpable nodule formation (20.0%), abscess (10.0%), and dermal fibrosis with inflammation (10.0%). @*Conclusion@#Regardless of the filler type, side effects can appear up to 12 years after injection. The most common type is a granulomatous lesion; however, it can appear as a non-granulomatous lesion. Therefore, when a patient visits with a nodule or an edematous lesion without any recall reason, careful history taking is needed to find any associated clues. With close follow-up and appropriate treatment, complications associated with injectable soft tissue fillers can be limited and competently managed.

Decompressive Sacral Foraminotomy for Nerve Root Injury during Conservative Treatment of Sacral Fracture: A Case Report

A 35-year-old woman visited the emergency department for a pedestrian traffic accident. Severe tenderness was noted at the posterior sacrum area, without open wound or initial neurologic deficit. Fracture of the left sacral ala extended to the S1 foramen, anterior acetabulum, and pubic ramus. Two weeks after the injury, she presented aggravating radiculopathy with the weakness of the left great toe plantar flexion. The S1 nerve root was compressed by the fracture fragments in the left S1 foramen. Decompressive S1 foraminotomy was performed. The postoperative follow-up computed tomography scan showed successful decompression of the encroachment, and the patient recovered well from the radiculopathy with motor weakness. She was able to resume her daily routine activity. We suggest that early decompressive sacral foraminotomy could be a useful additional procedure in selective sacral zone II fractures that are accompanied by radiculopathy with a motor deficit.

A Novel Fluoroscopic View for Positioning the AO Clavicle Hook Plate Decreases Its Associated in situ Complications

BACKGROUND: The goal of this study was to evaluate whether a modified fluoroscopic technique for positioning a hook plate affected the clinical results of treating Neer type II distal clavicle fractures and Rockwood type V acromioclavicular (AC) joint separations with this device. METHODS: The study was a retrospective consecutive case series with data analysis. Sixty-four patients with a Neer type II distal clavicle fracture or a Rockwood type V AC joint injury treated between March 2009 and June 2013 were divided into 2 groups: traditional fluoroscopic technique (traditional view, 31 patients) or modified fluoroscopic technique ('hook' view, 33 patients). A visual analogue scale (VAS) score, the modified University of California-Los Angeles (UCLA) shoulder scale score, and radiographic osteolysis were the main outcome measures. RESULTS: The traditional group included a significantly larger number of patients with acromial osteolysis than the hook view group: 23 patients (74.2%) vs. 11 patients (33.3%), respectively (p=0.01). Before plate removal, the hook group reported less pain and higher UCLA shoulder scale scores than the traditional group: average VAS score, 1.55 vs. 2.26, respectively; average UCLA score, 30.88 vs. 27.06, respectively. However, there was no significant difference after plate removal. CONCLUSIONS: The hook view allows more accurate bending of the hook plate around the contour of the acromion, resulting in decreased osteolysis, decreased pain, and better function with the plate in situ.

Meshed Stab Incision for Severe Swelling after Foot and Ankle Injury: A Technical Report / 대한족부족관절학회지

Swelling is a body's natural reaction to foot and ankle injury to mount a healing inflammatory response. To some degree, swelling is necessary for healing and is something that cannot be avoided following injury. However, post-traumatic swelling may have an adverse effect on wound healing and surgery can often be delayed due to preoperative swelling. We report on a unique technique of making multiple meshed stab incisions around the site of injury to reduce soft tissue swelling and promote wound healing.
