Superficial Temporal Fascia V-Y Advancement Flap for Delayed Complication in Cochlear Implantation.

Cochlear implantation (CI), a widely employed procedure for individuals with severe hearing loss, can encounter a serious complication in the form of implant exposure. In such instances, surgeons are tasked with deciding between salvage measures or opting for reimplantation with a healthy tissue covering. This case presented a challenge with delayed flap necrosis triggered by an increase in the magnetic force of the external device. Notably, this complication manifested 8 years after the initial operation. Following the removal of the device, it was reconstructed successfully using a superficial temporal fascia V-Y advancement flap.

Abdominal displacement of breast filler after previous trans-umbilical breast augmentation (TUBA): a case report.

Background: Breast augmentation is one of the most commonly performed aesthetic procedures in the world. Aquafilling filler, since its introduction in 2005 has been used for breast or buttock augmentation in several countries. Aquafilling filler is composed of 2% polyacrylamide with 98% sodium chloride 0.9% solution, and is known to have a similar composition with polyacrylamide hydrogel (PAAG) filler, which is also related to a variety of complications. Although many studies have warned against the complications of aquafilling filler, it is still being used for aesthetic purposes. Case Description: In this case report, we share our experience of a 36-year-old female patient complaining of smaller left breast and bulging mass in her left upper abdomen. She had a history of transumbilical breast augmentation (TUBA) 11 years prior, which she had had removed via the transumbilical incision 6 years ago. To compensate for the removal of implants, the patient had received large volumes of aquafilling filler injection 2 years after implant removal. Surprisingly, we found out that the filler in the left breast had displaced to the abdominal area. Conclusions: Accidently displacement may occur, especially in patients who have had previous procedures breaching the inframammary fold including TUBA. Therefore, it is required to observe carefully for those patients who have received breast augmentation or the breast filler injections.

Dupuytren contracture after acute traumatic hand injury in an adolescent: A case report.

Dupuytren's disease is a fibroproliferative disease that affects the palmar hand, causing progressive, permanent, and symptomatic flexion contracture of the digits. It is a disorder of polygenetic and multifactorial origin, usually affecting middle-aged males. Dupuytren's disease developing as a result of hand trauma in younger ages is rarely reported. In this case, we present a 14-year-old male patient with Dupuytren's disease following acute traumatic injury. We performed the fasciectomy and Z-plasty with full thickness skin graft. He recovered completely additional injection of triamcinolone for one year.

Giant lipoma in the index finger of the dominant hand of a swimmer: A case report.

Lipoma is a very common benign tumor that occurs in areas of adipose tissue and is commonly found on the whole body, although its occurrence in the hand and finger is rare. Giant lipoma, defined as over 5 cm long in diameter, is a rare benign tumor of abundant soft tissue in the finger. A 24-year-old male patient presented with a giant lipoma on the volar aspect of the index finger of his right hand. Magnetic resonance imaging (MRI) showed an encased multilobulated mass that measured 7.1x1.2x2.3 cm, and histopathological examination revealed lipoma without malignant transformation. Surgical resection of the tumor with a longitudinal and zig-zag incision of the palm was performed exposing the mass surrounding the palmar digital branch of the median nerve. The mass was completely removed, and neurorrhaphy was performed via the microscope to repair the damaged neurovascular bundle. At four months of postoperative follow-up, the patient was completely recovered with no finger paresthesia or limitation of range of motion. As a professional swimmer, the patient has experienced no subsequent difficulty in swimming due to his finger.

The Effect of Steroid and Mannitol Combination Treatment on Postoperative Rehabilitation of Multiple Metacarpal Bone Fractures.

Background and Objectives: The expedient resolution of postoperative soft tissue edema is particularly important in hand surgery. Prolonged edema and pain become an obstacle to postoperative rehabilitation, delay return to daily life, and in severe cases, lead to a permanent decrease in range of motion. Based on the common physiology between postoperative hand swelling and complex regional pain syndrome (CRPS), we sought to determine if postoperative mannitol and steroid administration to multiple metacarpal bone fracture patients effectively reduces hand swelling and pain and is beneficial for hand rehabilitation. Materials and Methods: From March 2015 to February 2019, 21 patients who received closed pinning for multiple metacarpal fractures were included in a retrospective cohort study. The control group (n = 11) underwent a routine recovery, while the treatment group (n = 10) received dexamethasone and mannitol injections for five days postoperatively. Serial changes in the degree of pain and fingertip-to-palm distance (FPD) were measured in both groups. The duration from surgery to the initiation of rehabilitation and time to full grip was also compared. Results: Compared to the control, the treatment group showed a faster alleviation of pain scores from the postoperative fifth day (2.91 versus 1.80, p = 0.013), and faster recovery of FPD from postoperative two weeks (3.27 versus 1.90, p = 0.002). Time to physical therapy initiation (6.73 versus 3.80 days, p = 0.002) and full grip achievement (42.46 versus 32.70 days, p = 0.002) were also faster in the treatment group. Conclusions: The steroid-mannitol combination treatment for multiple metacarpal bone fracture patients in the acute postoperative phase promoted the reduction of hand edema and pain, leading to the earlier initiation of physical therapy, rapid improvement in joint motion, and faster achievement of full grip.

Undifferentiated Pleomorphic Sarcoma of a Chronic Burn Scar of the Knee With Lymph Node Metastasis.

Malignant transformation of chronic burn scars are usually toward cutaneous lineages, including squamous cell carcinoma, basal cell carcinoma, and malignant melanoma. Sarcomas are less common. Undifferentiated pleomorphic sarcoma(UPS) is a subtype of soft tissue sarcoma with storiform-pleomorphic cells of uncertain origin, and has sparingly been reported to arise from burn scars. The majority are localized lesions probably due to the spatial distance of mesenchymal cells from the epithelium. The authors describe a rare case of UPS of the chronic burn scar of his knee with ipsilateral femoral and external iliac lymph node metastasis.

The Oblique Extended Reverse First Dorsal Metacarpal Artery Perforator Flap for Coverage of the Radial-Volar Defect of the Proximal Interphalangeal Joint in the Index Finger: A Case Report.

The dorsal metacarpal artery perforator flap is a flap that rises from the hand dorsum. Owing to its reliability and versatility, this flap is used as a workhorse for finger defect. However, to cover the radial-volar defect of the proximal interphalangeal joint (PIPJ) of the index finger, a longer flap is required than before. Here, we introduce the oblique extended reverse first dorsal metacarpal artery (FDMA) perforator flap to cover the radial-volar aspect defect of the index finger. A 45-year-old man got injured to the radial-volar defect of PIPJ of the left index finger caused by thermal press machine. The wound was 2 × 1 cm in size, and the joint and bone were exposed. We used FDMA perforator from anastomosis with palmar metacarpal artery at metacarpal neck. Since the defect was extended to the volar side, the flap was elevated by oblique extension to the fourth metacarpal base level. The fascia was included to the flap, and the flap was rotated counterclockwise. Finally, PIPJ was fully covered by the flap. Donor site was primarily closed. After 12 months of operation, the flap was stable without complication and limitation of range of motion. The oblique extended reverse FDMA perforator flap is a reliable method for covering the radial-volar defect of the PIPJ of the index finger. This flap, which also has an aesthetic advantage, will be a good choice for hand surgeons who want to cover the PIPJ defect of the index finger using a nonmicrosurgical option.

Closed extensor tendon rupture caused by Kienböck disease: a case report.

Kienböck disease, a rare disease that can cause chronic pain and motor dysfunction, occurs due to avascular necrosis of the lunate bone, which leads to dislocation of the carpal bone. Among various other etiologies, Kienböck disease can cause closed tendon rupture of the finger. In this report, we introduce a case of total rupture of the second extensor digitorum communis and the extensor indicis proprius tendons caused by undiagnosed Kienböck disease in an elderly female patient.

Apocrine tubular adenoma on the palm: A case report.

RATIONALE: Tubular apocrine adenoma (TAA) is a very rare benign neoplasm of the apocrine gland. The typical anatomical locations are mostly hair-bearing areas, where normal apocrine glands are abundant. PATIENT CONCERNS: We report the case of a 40-year-old patient with a tubular apocrine adenoma on a non-hair-bearing area. DIAGNOSES: Ultrasonography showed a 0.4-cm-sized hypoechoic nodule in the subcutaneous plane of the left palm at the fourth carpometacarpal joint level. INTERVENTIONS: Surgical resection was performed and histopathological examination revealed lobules of well-differentiated dilated tubular structures at the dermis level. OUTCOMES: At 1 year of postoperative follow-up, the patient was completely recovered without signs of recurrence. LESSONS: Diagnosis of TAA can be misleading due to its unusual location and inconspicuous appearance. Immunohistochemistry for epithelial membrane antigen and gross cystic disease fluid protein-15 is crucial for the proper diagnosis. Complete excision is recommended to prevent recurrence.

Propeller posteromedial thigh perforator flaps for coverage of extensive perineal defects.

BACKGROUND: Reconstruction of perineal defect is challenging. The goal of reconstruction is to maintain normal function with good esthetic outcomes. Coverage of the perineal defect is often difficult with one loco-regional flap when the size of defect is very extensive. In this article, clinical applications of the propeller posteromedial thigh perforator (PMTP) flap for extensive perineal defects were described. PATIENTS AND METHODS: Eight patients underwent perineal reconstruction with propeller PMTP flaps from March 2013 to December 2018. The average age of the patients was 65 years (range: 52-80 years). The causes of the defects included infection and skin cancers. The perforator was a branch of deep femoral artery. The flap was harvested as a perforator-based flap and rotated 180° to the defect area (propeller flap design). RESULTS: The average flap size was 256.5 cm2 (range: 136-400 cm2 ) and average follow-up period was 22.4 months (range: 6-48 months). All flaps survived after surgery without major complications. The donor sites were all primarily closed and the patients were all satisfied during the follow-up period. CONCLUSION: The propeller PMTP flap is an adequate new option for reconstructing extensive perineal defects. The flap avoids the need for microanastomosis and replaces the defect with similar tissue.

Chondrocutaneous posterior auricular artery perforator free flap for single-stage reconstruction of the nasal tip: a case report.

Full-thickness nasal tip reconstruction is a challenging process that requires provision of ample skin and soft tissue, and intricate cartilage structure that maintains its architecture in the long term. In this report, we describe reconstruction of a full-thickness nasal tip and ala defect using a posterior auricular artery perforator based chondrocutaneous free flap. The flap consisted of two lay ers of skin covering conchal cartilage, and was based on a perforating branch of the posterior auricular artery. A superficial vein was secured at the posterior margin. The donor perforator was anastomosed to a perforating branch of the lateral nasal artery. The superficial vein was connected to a superficial vein of the surrounding soft tissue. The donor healed well after primary closure. The flap survived without complications, and the contour of the nasal rim was sustained at follow-up 6 months later. As opposed to combined composite reconstructions using a free cartilage graft together with a small free flap or pedicled nasolabial flap, the posterior auricular artery perforator free flap encompasses all required tissue types, and is similar in contour to the alar area. This flap is a useful option in single-stage reconstruction of nasal composite defects.

A propeller superficial transverse cervical artery perforator flap for defect coverage of the submental area: a case report.

Reconstruction of submental defects is a challenge that needs to be approached carefully, since many important anatomical structures are located in this small space. Both aesthetic and functional outcomes should be considered during reconstruction. In this report, we describe a case where a superficial branch of the transverse cervical artery (STCA) perforator propeller flap was applied for coverage of the submental area. An 85-year-old woman presented with a 3-cm ovoid mass on her submental area. We covered the large submental defect with a STCA rotational flap in a 180° propeller pattern. The flap survived well without any complications at 1 year of follow-up. A STCA propeller flap is a useful surgical option in reconstruction for defect coverage of the submental area.

Angiolymphoid hyperplasia with eosinophilia attached to the masseter muscle.

Angiolymphoid hyperplasia with eosinophilia (ALHE) is a rare benign vascular tumor. The pathogenesis of ALHE is unknown; however, it may be linked to local trauma. ALHE predominantly occurs in areas of the preauricular region, forehead, and scalp; the masseter area is rarely involved. A 49-year-old man was referred for a mass in the right cheek region that was felt 2 months prior. Physical and imaging examination results suggested the presence of a benign tumor. Thus, surgical excision was performed. Pathologic findings confirmed an unexpected diagnosis of ALHE. This case was interesting, since the mass occurred at an unusual site with a misdiagnosis of an epidermal inclusion cyst.

A giant solitary vellus hair cyst on the nasal root.

Eruptive vellus hair cyst is a rare lesion of the vellus hair follicles as a result of developmental abnormality. This cyst is usually found in children, adolescents, and young adults most commonly involving the chest, upper and lower extremities, and abdomen. Herein, we introduce a 22-year-old male patient with a mass of nasal root, growing since childhood. The mass has grown over the years, causing the protruding of the nasal root contours, leading to decline in the patient's aesthetic and mental quality of life. In response, we performed complete resection of the mass, which pathologically was a vellus hair cyst. The patient is now satisfied with his appearance and there was no local recurrence during follow up.

Combination therapy using non-ablative fractional laser and intralesional triamcinolone injection for hypertrophic scars and keloids treatment.

Combinations of various treatment modalities were shown to be more effective than monotherapy when treating hypertrophic scars and keloids. This study was conducted to assess the effectiveness of combination therapy with non-ablative fractional laser and intralesional steroid injection. From May 2015 to June 2017, a total of 38 patients with hypertrophic scars or keloids were evaluated. The control group of 21 patients received steroid injection alone, and 17 patients (the combined group) received 1550-nm erbium-glass fractional laser treatment and steroid injection simultaneously. The mean number of treatment sessions was statistically fewer in the combined group than in the control group (6.95 vs 5.47, P = .042). There was a significant difference in the patient's scale in the combined group (14.62 vs 22.82, P = .005); however, the observer's scale was not significantly different (17.92 vs 20.55, P = .549). The recurrence rate was 38.1% (8/21) in the control group and 35.3% (6/17) in the combined groups and showed no significant difference (P = .859). However, the mean remission period was statistically longer in the combined group (3.00 months vs 4.17 months, P = .042). Combination therapy with non-ablative fractional laser and intralesional steroid injection showed better results for the treatment of hypertrophic scars and keloids with fewer treatment sessions, better patient satisfaction, and longer remission periods.

Necrotizing fasciitis of the masticator space with osteomyelitis of the mandible in an edentulous patient.

Necrotizing fasciitis (NF) is a rapidly progressive necrosis of the subcutaneous tissue and fascia, caused by bacterial infection. Usually presenting in the extremities, trunk, or perineum, it is uncommon in the craniofacial or cervical area. Cervicofacial NF is a potentially fatal infection, which should be managed with early detection and intervention. Most cases have a primary odontogenic source of infection, especially when the masticator space is involved. We report a case of masticator space NF that developed without odontogenic origin in a 78-year old female who was treated with prompt surgical drainage and intravenous antibiotics.

Acellular dermal matrix (Insuregraf) in the prevention of Frey's syndrome and surgical site depression after parotidectomy.

BACKGROUND: Parotidectomy is the treatment of choice in many parotid tumors. Due to the extensive nature of the procedure, unfavorable complications such as gustatory sweating, surgical site depression are common. Various techniques using fascia, muscle or AlloDerm have been developed but debate still remains regarding its availability and affordability. We applied a newly developed acellular dermal matrix (Insuregraf) to the parotidectomy field to act as a physical barrier and to provide adequate filling effect for prevention of functional and aesthetic complications. METHODS: From March 2010 to March 2017, 30 patients with parotid tumors underwent superficial parotidectomy. Twenty patients underwent only superficial parotidectomy. Ten patients had Insuregraf applied to the surgical site after superficial parotidectomy. We evaluated the incidence of Frey's syndrome, surgical site depression, and patient satisfaction rate in both groups. RESULTS: The incidence of Frey's syndrome was lower in the Insuregraf group (0 vs. 2). Surgical site depression was also lower in the Insuregraf group (2 vs. 20). Satisfaction score for facial contour in Insuregraf group was 9.2 out of 10, which was comparable to 6.2 out of 10 in the control group. CONCLUSION: Application of Insuregraf after superficial parotidectomy is an effective surgical procedure to prevent complications such as Frey's syndrome and surgical site depression. This technique is affordable and safe with no immune reactions. Above all this surgical method should be considered as an option for patients who are concerned about the contour of the face after surgery.

Eccrine porocarcinoma on the cheek.

Eccrine porocarcinoma is a rare malignant tumor arising from the intraepidermal ductal portion of the eccrine sweat gland. It develops either spontaneously or from a long standing benign eccrine poroma. This entity usually affects older people and is commonly located on the lower extremities, the trunk, and the head. We report a case of eccrine porocarcinoma on the left cheek in an 85-year-old male. In our case, the tumor was treated with wide excision and postoperative adjuvant radiation therapy. The patient recovered well without local recurrence and distant metastasis during the 14-month follow-up period. Wide excision and postoperative adjuvant radiation therapy can be considered as a safe and effective treatment option in treating patients with eccrine porocarcinoma.

Intraparotid facial nerve schwannomas.

Schwannoma is a benign tumor rarely found in the head and neck and much less commonly found in the intraparotid facial nerve. It is a slow-growing encapsulated tumor originating from the Schwann cells or axonal nerve sheath. It can occur anywhere along the course of the facial nerve. Patients may present with symptoms of facial palsy, but the most common presenting symptom is an asymptomatic swelling. Diagnosis is usually difficult before surgical removal and histopathological examination. We report a rare case of intraparotid facial nerve schwannoma in a 57-year-old female who had sustained a mass of the right preauricular area for 3 years. She reported no pain or facial muscle weakness. Enhanced computed tomography findings revealed the impression of pleomorphic adenoma. However, intraoperative gross findings were not characteristic of pleomorphic adenoma, and a frozen biopsy was performed resulting in the impression of a nerve sheath tumor. We performed an extracapsular surgical excision without parotidectomy. Permanent histopathology and immunohistochemistry reports diagnosed the mass as schwannoma. There were no complications including facial palsy after surgery. No recurrence was found at 6 months after surgery.
