Background: The annual incidence of skin cancer has been increasing, and surgical ablation is presently the treatment of choice for skin cancer. However, it leaves soft tissue defects that require reconstruction. The methods for reconstruction include locoregional flaps (LRFs) and full-thickness skin grafts (FTSGs). We compared these two surgical methods for reconstruction of defects in the nose, which is prominently visible and the most common site of facial skin cancer, and assessed the cosmetic results by evaluating the scars. Methods: This retrospective study was conducted between July 2012 and January 2021. Patients were evaluated for scars after at least 6 months of follow-up. Patients were divided into LRF and FTSG groups. The scars were evaluated using the Vancouver Scar Scale. Results: In total, 27 patients were included in this study. Their mean age was 66.8 years. Eighteen patients underwent LRF, and nine patients underwent FTSG. The average defect size was 1.55 cm² in the LRF group, and 1.38 cm² in the FTSG group. The average scar score was 1.44 points in the LRF group and 3.67 points in the FTSG group. The LRF group showed significantly lower total scores than the FTSG group. Conclusions Although LRFs and FTSGs are useful reconstructive methods for nasal soft tissue defects, this study showed that LRFs are superior to FTSGs in terms of aesthetic results.

Background: Although the zygomatic arch is an important structure determining facial prominence and width, no consensus exists regarding the classification of isolated zygomatic arch fractures, and the literature on this topic is scarce. To date, five papers have subdivided zygomatic arch fractures; however, only one of those proposed classifications includes the injury vector, although the injury vector is one of the most important factors to consider in fracture cases. Furthermore, the only classification that does include the injury vector is too complicated to be suitable for daily practice. In addition, the existing classifications are clinically limited because they do not consider greenstick fractures, nondisplaced fractures, or coronoid impingement. In the present study, we present a rearrangement of the previously published classifications and propose a modified classification of isolated zygomatic arch fractures that maximizes the advantages and overcomes the disadvantages of previous classification systems. Methods: The classification criteria for isolated zygomatic arch fractures described in five previous studies were analyzed, rearranged, and supplemented to generate a modified classification. The medical records, radiographs, and facial bone computed tomography findings of 134 patients with isolated zygomatic arch fractures who visited our hospital between January 2010 and December 2019 were also retrospectively analyzed. Results: We analyzed major classification criteria (displacement, the force vector of the injury, V-shaped fracture, and coronoid impingement) for isolated zygomatic arch fracture from the five previous studies and developed a modified classification by subdividing zygomatic arch fractures. We applied the modified classification to cases of isolated zygomatic arch fracture at our hospital. The surgery rate and injury severity differed significantly from fracture types I to VI. Conclusion Using our modified classification, we could determine that both the injury force and the injury vector meaningfully influenced the surgery rate and the severity of the injuries.

Keloid scars may cause a range of symptoms and aesthetic problems. The ear is one of the most frequent sites of keloids, and the earlobe and ear helix account for more than 80% of ear keloids. There are various surgical methods for removing keloids in the ear. Standard keloidectomy and core excision can be effective surgical methods compared to wedge resection since they preserve normal tissue surrounding the keloid. However, ears often show various types of asymmetry by default, which can be relatively difficult to detect, so wedge resection continues to be a useful surgical method for ear keloids. Here, we report four cases of keloids in the earlobe and ear helix that were successfully treated by wedge resection without a postoperative deformity or recurrence.

Background: Nasal bone fractures are the most common type of facial bone fracture, but are under-studied in adults above 65 years of age. Therefore, we investigated the epidemiology and patterns of nasal bone fractures among older adults in comparison to different age groups. Methods: This retrospective study included 2,321 nasal bone fracture patients who underwent surgery at our hospital from January 2010 to December 2017. The patients were classified by age as preschoolers, school-age children, young and middle-aged adults, and the elderly. We performed pairwise comparisons between elderly patients and each other age group in terms of sex, cause of injury, and fracture type. Results: The 2,321 nasal bone fracture patients included 76 elderly patients (50 men [65.8%] and 26 women [34.2%]). In these patients, the two most common injury causes were falling or slipping down (n = 39; 51.3%) and road traffic accidents (n = 19; 25.0%). According to the Stranc and Robertson classification, the most common force vector was lateral, and plane 2 fractures with lateral forces predominated. Conclusion The elderly showed similar patterns of nasal bone fractures to those observed in young and middle-aged adults, but significant differences from preschoolers (in the injury vector and plane of fracture) and from school-age children (in the sex ratio and plane of fracture). However, elderly patients presented significantly different epidemiological characteristics compared to the other three groups. Therefore, it is necessary to improve the quality of life of the elderly and prepare for the upcoming super-aged society by taking steps to reduce the incidence and severity of fractures. Possible options for doing so include strengthening individual-level safety factors and expanding the social safety net for the elderly.
