Background: Adipose tissue-derived stem cells (ASCs) represent a rapidly evolving area of cell-based therapies. ASCs are harvested from the stromal vascular fraction (SVF), a heterogeneous mixture of ASCs and other cell types. Two methods are typically employed to obtain the SVF: enzymatic and mechanical. In this study, we examined the efficacy of ultrasonic cavitation in isolating the SVF from adipose tissue. Methods: Human adipose tissue was procured from three patients through an aesthetic liposuction procedure. This tissue was then subjected to either an enzymatic method utilizing type II collagenase or an ultrasonic cavitation method using an Ultra Stemcell device. The cell counts and viability were determined using a cell counter. The immunophenotype of the SVF was analyzed using real-time polymerase chain reaction. Results: Compared to the enzymatic method, the total cell count and cell viability of the SVF isolated through ultrasonic cavitation were relatively low. However, no significant difference was observed in the immunophenotype of CD45, CD11b, CD34, and CD105. Conclusions The ultrasonic cavitation method constitutes a clinically practical approach that offers straightforward access in the operative field. This technique is a rapid and cost-effective method for isolating the SVF.

Scars are still a challenging problem in medical practice, despite advancements in treatment modalities. Numerous treatment modalities, ranging from simple revision, Z-plasty, and W-plasty to laser treatments, have been used to treat scar deformities. However, for wide depressed scars, additional methods are needed to completely restore the contour of the depression caused by tissue adhesion. We report on the case of a 34-year-old woman with a wide depressed scar deformity on the left upper buttock and the encouraging results of an autologous fat graft injection technique that utilized a cutting wire to form a pocket for the fat graft site, while simultaneously resolving the adhesion caused by the tissue. This method is safe and easily reproducible, making it a useful addition to the surgeon’s toolkit when dealing with such lesions.

White-eyed blowout fractures with extraocular muscle (EOM) entrapment necessitate emergency surgical intervention. However, even after surgery, diplopia or EOM motion limitations may persist due to the incomplete reduction of soft tissue herniation caused by inadequate dissection or unresolved muscle strangulation. In this report, we present a case of postoperative EOM movement limitation in a 5-year-old girl who experienced recurrent restriction in the upward gaze of her right eye 14 days after surgery. Instead of revision surgery, the patient was treated with targeted EOM exercises focusing on the inferior rectus muscle and inferior oblique muscle. The patient was instructed to slowly move her pupils from the central point to the upper and outer sides, then in a straight line from the central point to the lower and inner sides before returning to the center point. On the 28th postoperative day, 2 weeks after initiating the exercises, the patient’s EOM motion fully recovered. This case highlights the effectiveness of EOM exercises as a non-surgical treatment approach for improving recurrent EOM movement limitations in the absence of soft tissue herniation following surgical management of blowout fractures in children.

Botulinum toxin treatment is the most common non-surgical cosmetic treatment. Although there are many available treatments using botulinum toxin, their effects are temporary and repeated injections are required. These frequent injections can trigger an immunological response. In addition, botulinum toxin acts as an antigen in the body; thus, its effect disappears progressively due to this immunological reaction, which may cause treatment failure. Active botulinum toxin consists of a core neurotoxin and complexing proteins, the exact effects of which remain unclear. However, the complexing proteins are closely related to the immune response and the formation of neutralizing antibodies. Since neutralizing antibodies can lead to treatment failure, their formation should be prevented. Furthermore, various methods of detecting neutralizing antibodies have been used to predict treatment failure.

Background: For the correction of small breasts with grade I ptosis, it is very challenging for plastic surgeons to obtain excellent aesthetic results by performing simultaneous breast augmentation and nipple-areolar complex (NAC) lifting. Previous research has introduced one-stage augmentation mastopexy, but most studies described using the periareolar approach. The current study proposes a technique for augmentation mastopexy using the inframammary fold approach for augmentation and the periareolar approach for mastopexy. Methods: Twenty patients were enrolled, and surgery was performed on 40 breasts. A pocket was made with the inframammary fold approach and the dual-plane method; subsequently, a tear-drop shape implant was inserted using a funnel. We performed NAC lifting using the de-epithelialization and interlocking purse-string suture method through the periareolar approach. Results: The mean distance from the mid-clavicular line to the nipple was 23.4 cm preoperatively, 19.6 cm at 7 days of follow-up, and 20.3 cm at 12 months of follow-up. Complications such as hematoma, infection, NAC necrosis, capsular contracture, and wound dehiscence were not reported. Conclusions We performed successful breast augmentation and mild ptosis correction. No specific complications were observed during 1 year of postoperative follow-up. Our method is a simple and fast method that enables surgeons to perform augmentation and mastopexy in one stage for breasts with grade I ptosis.

Retrobulbar hemorrhage is a disastrous condition that can lead to permanent blindness. As such, rapid diagnosis and treatment are critical. Here, we report a patient who presented with retrobulbar hemorrhage following an orbital floor fracture. Restoration of inferior orbital wall with porous polyethylene implant was underwent. Four days after the orbital floor reconstruction, the patient smoked a cigarette outdoors in –3˚C weather. Cold temperature and smoking caused an increase in his systemic blood pressure. The elevated blood pressure increased intraorbital pressure to the extent of causing central retinal artery occlusion and exacerbated oozing. During exploratory surgery, 3 mL of hematoma and diffuse oozing without arterial bleeding were observed. Prompt diagnosis and treatment prevented vision impairment. Few studies have reported on the risk factors for retrobulbar hemorrhage. This case showed that daily activities, such as exposure to cold weather or tobacco smoking, could be risk factors for retrobulbar hemorrhage.

Background: Capsular contracture is a frequent complication of breast augmentation that constitutes one of the most common reasons for secondary operations. Capsular contracture is treated surgically, often with total capsulectomy. Therefore, in this study, we aimed to study correlations among intraoperative observations, physical examination findings, and characteristics of the previous operation in patients with capsular contracture who underwent total capsulectomy. Methods: A retrospective chart review was conducted for patients treated from May 2017 to April 2019, analyzing 24 breasts in 12 female patients. The patients were classified in terms of the Baker grade, incision type, implant type, and implant plane. During the operation, we evaluated the ease of dissection based on intraoperative features such as anterior and posterior wall dissection, bleeding tendency, and scar length. Statistical analysis was performed to identify association between variables Results: The implant was changed in eight patients, while only explantation was performed in the remaining four patients. The ease of capsule dissection had a proportional correlation with the Baker grade (P=0.005). Intraoperative dissection was significantly easier in the inframammary fold (IMF) group than in the periareolar group (P=0.035). Conclusions An IMF incision is preferable for planning en bloc capsulectomy. However, for aesthetic concerns, a periareolar incision would be preferable. In addition, a lower Baker grade (grade I or II) was associated with easier dissection. Therefore, surgeons should choose the incision type depending on the necessity of performing en bloc capsulectomy, Baker grade, and scar length.
