A 42-year-old female patient presented with a complete ear amputation resulting from a collision with a machine. The ear was avulsed by blunt trauma, meaning that it was torn away rather than being cleanly cut. Fortunately, the auricular cartilage remained intact and preserved its overall shape despite the amputation. However, the surrounding blood vessels were not suitable for microanastomosis. In the first-stage operation, the auricular cartilage was de-epithelialized and embedded into the postauricular area. Three months later, during the second-stage operation, the embedded auricular cartilage framework was elevated to achieve normal auricular projection. During the postoperative period, a customized mold based on the shape of the patient’s contralateral ear was fabricated using 3D printing technology and applied to the reconstructed ear to refine the contour and achieve a natural appearance. The overall outcome was favorable, with no complications observed during the postoperative care period.

Elastofibroma is a rare soft tissue tumor that most commonly occurs in the subscapular region. It has also been reported in several other anatomical locations. To our knowledge, no previous reports have described elastofibromas in the anterior aspect of the face. A 36-year-old man with intellectual disability was referred to our department for the evaluation of a painless multinodular lesion on the philtrum. The lesion was initially misdiagnosed as a dermatologic condition by the department of dermatology and was treated accordingly, however, it worsened, prompting referral to our department. We performed a surgical excision of the lesion and reconstructed the resulting skin defect with a skin graft. Histopathological examination confirmed the diagnosis of elastofibroma. This case underscores the importance of including elastofibroma in the differential diagnosis of facial neoplasms, particularly when the presentation is phymatous.

With the growth of the population of older adults, cement-augmented pedicle screws (CAPS) have become more commonly employed. Although CAPS are considered safe, cement leakage can occur, leading to complications. Neurological symptoms resulting from bone cement leakage pose significant challenges in both diagnosis and treatment. Unilateral biportal endoscopy (UBE) offers a minimally invasive solution for these issues. UBE enables a thorough exploration of potential compression sites, allowing precise visualization of the entire nerve roots without necessitating removal of the instrument or compromising spinal stability. Additionally, it facilitates the removal of cement fragments under direct vision. Herein, we present the case of an 84-year-old female patient who underwent endoscopic interbody fusion of L4–5. After surgery, she presented with radiating pain in the right lower extremity. Postoperative magnetic resonance imaging indicated indirect evidence of cement leakage under the right L5 pedicle screw. The patient underwent UBE exploration under spinal anesthesia. During the procedure, the cement fragment was detected and removed without complication. UBE can also be performed under local or regional anesthesia, significantly reducing the anesthetic risk for medically fragile individuals. Using UBE, it is also possible to monitor neurological function while manipulating the neural tissue. UBE is a viable option for both the diagnosis and treatment of cement leakage following CAPS placement.

Objective: With advances in endoscopic surgery, L5–S1 foraminotomy has become a readily accessible surgical technique. However, symptom relief is often short-lived, and recurrence is common. As an alternative, biportal endoscopic fusion at L5–S1 can improve symptoms. However, it can be challenging and may lead to fusion-related complications. Therefore, we aimed to compare 2 procedures for L5–S1 foraminal stenosis. Methods: A total of 37 patients diagnosed with L5–S1 foraminal stenosis were divided into 2 groups for this study. Group 1, comprising 18 patients, underwent L5–S1 foraminotomy via a paraspinal approach from 2017 to 2019. Group 2, comprising 19 patients, underwent biportal endoscopic L5–S1 fusion with the facet-sacrificing approach from January 2021 to August 2023. A comprehensive evaluation of both groups was conducted using various metrics, including image findings, operation time, hospital stay, visual analogue score (VAS) back, VAS leg, Oswestry Disability Index (ODI), and the MacNab criteria. Postsurgical complications were meticulously recorded. The statistical analysis was performed using the Wilcoxon signed-rank test, and differences between the 2 surgical approaches were assessed using the Mann-Whitney U-test. Results: No statistically significant difference was found in VAS back or ODI improvement between the 2 groups. However, the foraminotomy group exhibited a statistically significant advantage in terms of operation time and hospital stay. Conversely, the fusion group demonstrated statistically significant improvements in VAS leg and McNab criteria in comparison to the foraminotomy group. The most prevalent complication observed in the foraminotomy group was early symptom recurrence, while the fusion group experienced complications related to screw-related issues and infections. Conclusion Leg symptoms recurred more frequently in the foraminotomy group. Biportal endoscopic facet-sacrificing transforaminal lumbar interbody fusion surgery has been demonstrated to be a valuable technique for L5–S1 fusion with lower recurrence of leg symptoms; however, it is associated with complications specific to fusion.

Fungal sinusitis is relatively rare, but it has become more common in recent years. When fungal sinusitis invades the orbit, it can cause proptosis, chemosis, ophthalmoplegia, retroorbital pain, and vision impairment. We present a case of an extensive orbital floor defect due to invasive fungal sinusitis. A 62-year-old man with hypertension and a history of lung adenocarcinoma, presented with right-side facial pain and swelling. On admission, the serum glucose level was 347 mg/dL, and hemoglobin A1c was 11.4%. A computed tomography scan and a Waters’ view X-ray showed right maxillary sinusitis with an orbital floor defect. On hospital day 3, functional endoscopic sinus surgery was performed by the otorhinolaryngology team, and an aspergilloma in necrotic inflammatory exudate obtained during exploration. On hospital day 7, orbital floor reconstruction with a Medpor Titan surgical implant was done. In principle, the management of invasive sino- orbital fungal infection often begins with surgical debridement and local irrigation with an antifungal agent. Exceptionally, in this case, debridement and immediate orbital floor reconstruction were performed to prevent enophthalmos caused by the extensive orbital floor defect. The patient underwent orbital floor reconstruction and received intravenous and oral voriconazole. Despite orbital invasion, there were no ophthalmic symptoms or sequelae.

An epidermal cyst, also known as an epidermoid cyst or epidermal inclusion cyst, is the most prevalent type of cutaneous cyst. This noncancerous lesion can appear anywhere on the body, typically presenting as an asymptomatic dermal nodule with a visible central punctum. In the case presented herein, an epidermal cyst with uncommon features was misdiagnosed as a lymphatic malformation based on preoperative magnetic resonance imaging (MRI). A 61-year-old man came to us with a swollen left cheek that had been present for 11 months. The preoperative MRI revealed a 3 × 3.8 × 4.6 cm lobulated cystic lesion with thin rim enhancement in the left masticator space. The initial differential diagnosis pointed toward a lymphatic malformation. We proceeded with surgical excision of the lesion via an intraoral approach, and the specimen was sent to the pathology department. The pathological diagnosis revealed a ruptured epidermal cyst, indicating that the initial diagnosis of a lymphatic malformation based on preoperative MRI was incorrect. Epidermal cysts located under the muscle with no visible central punctum are uncommon, but should be considered if a patient presents with facial swelling.

Background: To compare the sensory change and recovery of infraorbital area associated with zygomaticomaxillary and orbital floor fractures and their recoveries and investigate the factors that affect them. Methods: We retrospectively reviewed 652 patients diagnosed with zygomaticomaxillary (n= 430) or orbital floor (n= 222) fractures in a single center between January 2016 and January 2021. Patient data, including age, sex, medical history, injury mechanism, Knight and North classification (in zygomaticomaxillary fracture cases), injury indication for surgery (in orbital floor cases), combined injury, sensory change, and recovery period, were reviewed. The chi-square test was used for statistical analysis. Results: Orbital floor fractures occurred more frequently in younger patients than zygomaticomaxillary fractures (p< 0.001). High-energy injuries were more likely to be associated with zygomaticomaxillary fractures (p< 0.001), whereas low-energy injuries were more likely to be associated with orbital floor fractures (p< 0.001). The sensory changes associated with orbital floor and zygomaticomaxillary fractures were not significantly different (p= 0.773). Sensory recovery was more rapid and better after orbital floor than after zygomaticomaxillary fractures; however, the difference was not significantly different. Additionally, the low-energy group showed a higher incidence of sensory changes than the high-energy group, but the difference was not statistically significant (p= 0.512). Permanent sensory changes were more frequent in the high-energy group, the difference was statistically significant (p= 0.043). Conclusion The study found no significant difference in the incidence of sensory changes associated with orbital floor and zygomaticomaxillary fractures. In case of orbital floor fractures and high-energy injuries, the risk of permanent sensory impairment should be considered.

The soft tissue triangle is an easily recognizable subunit of the nose. Therefore, deformities in this region resulting from trauma or complications after cosmetic surgery can have serious cosmetic impacts. Various reconstruction choices exist for deformities such as depression of the soft triangle but choosing the most appropriate treatment in each case remains a challenge. In the case described herein, a patient underwent augmentation rhinoplasty with a silastic implant and experienced implant exposure in the soft triangle area. After implant removal, the patient complained of depression in this area. The authors effectively solved this problem through a de-epithelialized composite tissue graft. In this report, we present this case and review similar cases of reconstruction of the soft triangle.
