A Case of Postoperative Silicone Magnet Compression Treatment of Pseudocyst in the Ear / 대한두경부종양학회지

Endochondral pseudocyst of the ear is a rare, benign, non-inflammatory cystic disease. It is known that there are a variety of treatment methods for pseudocyst, which is mainly common in the scaphoid or triangular fossa of the ear. Pseudocyst formation is prevalent in the residual cavity of the ear. So, to prevent a recurrence, a surgical approach is also required, but management through compression is necessary after surgery. Applying a cube magnet to the lesion to press provides patient convenience and facilitates continuous management.

Usefulness of the Lower Trapezius Myocutaneous Pedicle Flap for Reconstruction of Third Degree Facial Burn

Free flap surgery is commonly used for extensive facial burn. However, free flap surgery requires long operation time and difficult technique. Also, it requires further procedure to prepare the recipient vessels. Hence, applying pedicle flap surgery instead of free flap surgery is effective for patients with facial burn. Among a wide range of pedicle flaps, we performed lower trapezius myocutaneous pedicle flap to patients with third degree facial burn and got satisfactory results without complications. Lower trapezius myocutaneous pedicle flap has a wide arc of rotation so that it can cover middle and lower part of the face. Furthermore, it is thinner than other myocutaneous pedicle flap that can be used for facial reconstruction. Due to these advantages, lower trapezius myocutaneous pedicle can be an attractive option for the reconstruction of facial burn.

The Usefulness of the Two-Staged Pedicled Latissimus Dorsi (LD) Flap in Fourth-Degree Burns of Upper Extremity

Purpose@#A large defect by fourth-degree burns in the upper limb requires flap reconstruction. Since severe vascular damage and decrease in blood circulation after vascular anastomosis can occur in defects caused by fourth-degree burns. Because of the disadvantages, it is difficult to apply free flap surgery to fourth-degree burns. We reconstructed a upper extremity using the pedicled Latissimus Dorsi (LD) flap in two stages. The purpose of our study is to review our experience and suggest two-staged pedicled Latissimus Dorsi (LD) flap in fourth-degree burns of upper extremities. @*Methods@#A retrospective review was performed from 2016 to 2019, on a total of 12 fourth-degree burn patients undergone two-staged pedicled LD flap surgery as reconstruction of upper extremities in our hospital. We reviewed the location of the injury, etiology, TBSA (%), size of burns requiring flap surgery, period from 1st surgery to secondary division surgery, complications. @*Results@#Using two-staged LD flap as a primary reconstruction, the outcome is satisfactory. This flap preserves the elbow joint and maintains the length of the forearm. We obtain low donor-site morbidity, simplicity and a small incision in the donor site. @*Conclusion@#Using two-staged LD flap in fourth-degree burns of upper extremity is effective, such as preserving elbow joint and maintaining the length of the forearm. Successful reconstruction was achieved with excellent cosmetic results with reducing a postoperative scar, donor-site morbidity. Due to these advantages, two-staged pedicled LD flap can be an optimal option for reconstruction of fourth-degree burns in the upper limb.

Reconstruction of Postburn Scar Contracture of the Sole Using the Medialis Pedis Free Flap

Postburn scar contracture of sole can cause musculoskeletal deformity, restricted range of motion, and decreased quality of life. It is very important to exhibit similar characteristics of the sole when reconstructing the sole because it has to resist shearing force and weight bearing. In this case, we performed medialis pedis free flap for the postburn scar contracture of the sole and the flap survived without complication. The patient satisfied with functional and aesthetic outcomes. Medialis pedis free flap, which is harvested adjacent to the sole, can show similar characteristic of the sole and maintain adequate contour.Moreover, this flap can be harvested without sacrifice of major vessel or nerve. Due to these advantages, medialis pedis free flap can be an ideal option for the reconstruction of the sole.

Intramuscular hemangioma in the zygomaticus minor muscle: a case report and literature review

Intramuscular hemangioma is a rare vascular benign proliferation that can occur within any muscle, particularly in the trunk and extremities. In the head and neck region, the masseter muscle is most commonly involved, followed by the periorbital and sternocleidomastoid muscles. Diagnosing intramuscular hemangioma is challenging because there are no characteristic symptoms; instead, magnetic resonance imaging is the best imaging modality to diagnose these lesions. Complete surgical resection is the treatment of choice, although the local recurrence rate is high. Herein, we report a rare case of intramuscular hemangioma located in the zygomaticus minor muscle, which is related to smiling and usually runs along the orbicularis oculi muscle. Distinguishing or separating these two muscles is challenging. However, based on the muscle vector of the midface and radiological findings, the two muscles were successfully separated. The zygomaticus minor was cut very slightly to approach to the lesion and the muscle fibers were split to excise it. A follow-up examination revealed no nerve damage or muscle dysfunction at 4 weeks postoperatively. This rare case may serve as a reference for managing intramuscular hemangioma in the head and neck region.

Basal cell carcinoma misdiagnosed as trichoepithelioma

Trichoepithelioma is a benign hair follicle tumor that can undergo malignant transformation into basal cell carcinoma in rare cases. Due to the similar clinical and histological features of trichoepithelioma and basal cell carcinoma, distinguishing between these types of tumors can be a diagnostic challenge. Punch biopsy obtains only a small sample of the entire lesion, and thus inherently involves a risk of misdiagnosis between histologically similar diseases. Therefore, if the possibility of misdiagnosis can reasonably be suspected, clinicians should conduct an excisional biopsy or immunohistochemical staining (e.g., CD10 and Bcl-2) to ensure an exact diagnosis. Although trichoepithelioma is benign, the surgical excision of solitary trichoepithelioma should be considered in order to avoid the possibility of malignant transformation, which has occasionally been documented for multiple familial trichoepitheliomas. Herein, we report a case that was initially misdiagnosed as trichoepithelioma before ultimately being diagnosed as basal cell carcinoma through excision and immunohistochemical staining.

Clinical factors in patients with congenital muscular torticollis treated with surgical resection

BACKGROUND: Congenital muscular torticollis (CMT) is characterized by persistent head tilt toward the affected side. No consensus exists regarding the cause of this disorder. In this study, we analyzed various clinical factors in patients with CMT who were treated with surgical release. This analysis enabled us to identify potential causative factors of CMT and to establish a basis for surgical interventions. METHODS: In total, 584 patients who underwent surgical intervention for CMT from October 2007 to December 2016 were included in this study. Their demographic characteristics, birth-related factors, and clinical features were analyzed. RESULTS: Data from 525 patients were analyzed in this study after exclusion of those with insufficient information. Before birth, 31 patients (5.9%) were diagnosed with oligohydramnios, and 87 (16.6%) had a breech presentation. Seven (1.3%) cases of clavicle fracture and two (0.4%) cases of cephalohematoma were noted at birth. Before surgery, 397 patients (75.6%) underwent physiotherapy and 128 patients (24.4%) did not. The duration of physiotherapy ranged from 1 to 50 months (average, 6 months). CONCLUSIONS: Our study shows that 16.6% of the CMT patients presented in the breech position, which is a much higher rate than that observed in the general population (3%–4%). We hypothesize that being in the breech position as a fetus appears to exert a significant influence on shortening and fibrosis of the sternocleidomastoid muscle.

Solitary mastocytoma presenting at birth

Mastocytosis is a rare disease which occurs in both children and adults, and it can manifest as a solitary or multiple skin lesions. Both can cause cutaneous or systemic symptoms. Because of the heterogeneity of clinical presentation of mastocytosis and its rare prevalence, it can be hard to suspect the mastocytosis at the first time. Most solitary mastocytomas are about 1–5 cm in diameter and have features of brownish-yellow, minimally elevated plaques with a smooth shiny surface. This article presents a case of solitary mastocytoma which occurred in neonate and that we treated through surgical excision. In histopathological examination, it consisted of c-kit-positive mast cells. Although pediatric cutaneous mastocytosis might regress spontaneously, clinicians should keep in mind that it could be associated with systemic mastocytosis which involves hematopoietic system.

Analysis of prognostic factors affecting poor outcomes in 41 cases of Fournier gangrene

PURPOSE: We present our experience involving the management of this disease, identifying prognostic factors affecting treatment outcomes. METHODS: The patients treated for Fournier gangrene at our institution were retrospectively reviewed. Data collected included demographics, extent of soft tissue necrosis, predisposing factors, etiological factors, laboratory values, and treatment outcomes. The severity index and score were calculated. Multivariate regression analysis was used to determine the association between potential predictors and clinical outcomes. RESULTS: A total of 41 patients (male:female = 33:8) were studied. The mean age was 54.4 years (range, 24–79 years). The most common predisposing factor was diabetes mellitus (n = 19, 46.3%). Sixteen patients (39.0%) were current smokers. Seven patients had chronic kidney disease. The most frequent etiology was urogenital lesion (41.5%). The mortality rate was 22.0% (n = 9). Multivariate regression analyses showed that extension of necrosis beyond perineal/inguinal area and pre-existing chronic kidney disease were significant and independent predictors of mortality. Extension of necrosis beyond perineal/inguinal area was a significant predictor of increased duration in the intensive care unit and hospital stay. In addition, pre-existing chronic kidney disease was a significant predictor of flap reconstruction in the wound. CONCLUSION: Fournier gangrene with extensive soft tissue necrosis and pre-existing chronic kidney disease was associated with poor prognosis and complexity of patient management. Early recognition of dissemination and premorbid renal function is essential to reduce mortality and establish a management plan for this disease.

Reduction of Closed Frontal Sinus Fractures through Suprabrow Approach

BACKGROUND: The traditional approach for reduction of frontal sinus fractures is coronal incision. Inherent complications of the coronal approach include long scar, hair loss, and long operation time. We describe a simple approach for the reduction of frontal sinus anterior wall fractures using a suprabrow incision that is commonly used for brow lift. METHODS: From March 2007 to October 2016, the authors identified patients with anterior wall frontal sinus fractures treated by open reduction through a suprabrow incision. Only cases with photographic/radiographic documentation and a minimum follow-up of 6 months were included. The incision line was designed to be at the upper margin of the eyebrow. Medical records and radiographic data were retrospectively reviewed. Surgical outcomes, cosmetic results, and complication were assessed. The patient scale of the patient and observer scar assessment scale was used to assess patient satisfaction for incisional scar at the 6-month follow-up. RESULTS: Thirty-one patients underwent fracture reduction through a suprabrow approach during the study period, with a mean follow-up of 41 months. No patients showed any recurrent displacement, eyebrow asymmetry, or infection during follow-up. Thirteen patients reported their forehead paresthesia postoperatively, and 12 of them had preoperative symptom. One patient complained of incisional scar and underwent scar revision. All patients were satisfied with their eyebrow and forehead contour. CONCLUSION: The suprabrow approach allowed for an accurate reduction of the fractures in the anterior wall frontal sinus by providing direct visualization of the fracture. This transcutaneous approach can effectively restore forehead contour with acceptable postoperative complications and patient satisfaction.

Vascularized Free Lymph Node Flap Transfer in Advanced Lymphedema Patient after Axillary Lymph Node Dissection / 한국유방암학회지

Lymphedema is a condition characterized by tissue swelling caused by localized fluid retention. Advanced lymphedema is characterized by irreversible skin fibrosis (stage IIIb) and nonpitting edema, with leather-like skin, skin crypts, and ulcers with or without involvement of the toes (stage IVa and IVb, respectively). Recently, surgical treatment of advanced lymphedema has been a challenging reconstructive modality. Microvascular techniques such as lymphaticovenous anastomosis and vascularized lymph node flap transfer are effective for early stage lymphedema. In this study, we performed a two-stage operation in an advanced lymphedema patient. First, a debulking procedure was performed using liposuction. A vascularized free lymph node flap transfer was then conducted 10 weeks after the first operation. In this case, good results were obtained, with reduced circumferences in various parts of the upper extremity noted immediately postoperation.

Reconstruction of a Mangled Foot with an Anterolateral Thigh Free Flap

PURPOSE: In recent decades, amputation is still recommended for patients with extensive lower extremity wounds requiring coverage. Although the feet contribute relatively little to total body surface area, they are essential organ for ambulation, and a high mortality rate after amputation has been reported. We report on 10 challenging cases of a mangled foot which was reconstructed using an anterolateral thigh (ALT) free flap, and analyze the advantages and disadvantages of this technique. MATERIALS AND METHODS: This retrospective study was conducted on 10 patients who underwent reconstructive surgery on a foot. Patients' charts were reviewed for age, sex, causes, defect size and site, flap size and type, flap type, and complications. Cases with a defect size of >100 cm2 were included. RESULTS: Seven of the 10 patients were male, and overall mean age was 38.5 years (range, 22 to 61 years). Mean defect size was 179.6 cm2 (range, 104 to 330 cm2), and mean flap size was 193 cm2 (range, 120 to 408 cm2). Three cases were reconstructed with a musculocutaneous free flap and seven cases were reconstructed with a fasciocutaneous free flap. There were two occurrences of local wound complication. All ten flaps survived well, however five patients underwent a debulking procedure to reduce flap volume. CONCLUSION: Reconstruction of a near completely degloved soft tissue defect or a wide defect containing two or more surfaces of extremity with an ALT free flap was performed. The purpose of this case study is to report on free tissue transfer using the ALT flap for salvage of the lower extremity.

The Adipofascial V-Y Advancement Flap with Skin Graft for Coverage of the Full-Thickness Burns of the Gluteal Region

Any types of burn injury that involve more than deep dermis often require reconstructive treatment. In gluteal region, V-Y fasciocutaneous advancement flap is frequently used to cover the defect. However, in case of large burn wounds, this kind of flap cannot provide adequate coverage because of the lack of normal surrounding tissues. We suggest V-Y adipofascial flap using the surrounding superficially damaged tissue. We present the case of a patient who was referred for full-thickness burn on gluteal region. We performed serial debridement and applied vacuum-assisted closure device to defective area as wound preparation for coverage. When healthy granulation tissue grew adequately, we covered the defect with surrounding V-Y adipofascial flap and the raw surface of the flap was then covered with split-thickness skin graft. We think the use of subcutaneous fat as an adipofascial flap to cover the deeper defect adjacent to the flap is an excellent alternative especially in huge defect with uneven depth varying from subcutaneous fat to bone exposure in terms of minimal donor site morbidity and reliability of the flap. Even if the flap was not intact, it was reuse of the adjacent tissue of the injured area, so it is relatively safe and applicable.

Application of Hand Towel Drape over Dingman Mouth Gag

In cleft palate surgery, the environment is especially critical when suturing. Encum-bered, obstructive space in the environment can hinder a suture while using the Dingman mouth gag. We introduced a novel but simple draping technique. A simple hand towel is placed over the gag. A hole is cut out in the middle according to each patient's mouth. After making the hole, the hand towel is soaked in water and gently squeezed. Then the towel is properly placed over the Dingman mouth gag. Dripping water on the hand towel during the suture helps keep it in place. Using this draping technique, we cut 14 minutes of operation time compared to the average operation time of the past 2 years. There were several disadvantages in previous draping method. First, long suture material may easily get caught. Second, the operation field can easily be contaminated. Third, focusing on the operation becomes difficult due to the obstruction. This draping technique can compensate for the disadvantages of the previous Dingman mouth gag.

A Surgical Technique for Congenital Preauricular Sinus

BACKGROUND: Preauricular sinuses represent a common congenital abnormality in children. Classically, a preauricular sinus manifests as a small opening, usually near the anterior limb of ascending helix. The difficulty in the surgical treatment of preauricular sinus is the high recurrence rate. The aim of this article is to review the outcomes of preauricular sinus and to introduce our surgical technique and its prognosis. METHODS: A single-institutional retrospective review was performed for all patients who had undergone excision of congenital periauricular sinus between October 2007 and April 2014. Medical records were reviewed for demographic information, wound complication, and recurrence rate. The sinus tract was visualized with the aid of preoperative dye instillation and intraoperative probe insertion. The skin next to the sinus opening was incised elliptically, and the tract itself was dissected medially to the end of the sinus tract and posteriorly to the cartilage of the ascending helix. RESULTS: The review identified 44 patients for a total of 57 preauricular sinus tracts. The mean age at time of operation was 16.3 years with a range from 9 months to 65 years. Unilateral preauricular sinus tract was present in 31 patients (11 right and 20 left preauricular tract), and 13 patients had bilateral sinus tract. None of the patients had experienced wound issues postoperative, and there were no recurrent sinus tract formation or infection. CONCLUSION: Using a combination of dye instillation, probe insertion, and modified dissection, we were able to achieve a recurrence free series of preauricular sinus tract excision among a heterogenous group of patients. A large patient series is necessary to replicate the results of this study.

Improvement of Congenital Muscular Torticollis with Mild Symptoms in Non-Treated Adult after Simple Surgical Myotomy of Sternocleidomastoid Muscle under Local Anesthesia

In adult congenital muscular torticollis (CMT) patients, physical therapy is not as effective because the development of sternocleidomastoid muscle (SCM) muscle is complete. While surgical release can address CMT in adult patients, the risk of general anesthesia and visible postoperative scar is a concern, expecially in patients with mild symptoms. In this paper, we report our experience in treating such patients with minimal-incision myotomy under local anesthesia. A review was performed for all adult patients who had undergone the simple myotomy procedure. Surgical indication was reserved for patients with mild fibrotic band in the SCM muscle with minimal lengthdiscrepancybetween the muscles. All patients had recognizable head tiltand palpation of fibrotic band on affected side of the neck. Surgical details are described in the main body of text. Three female patients had undergone the procedure. Torticollis was resolve in all patients with complete restoration of ranage of motion. There were no postoperative complications, and patient satisfaction was high. We have reported three cases of mild CMT in adult female patients, who had undergone minimal-incision myotomy under local anesthesia. Outcomes were satisafactory with no morbidity to report. With careful patient selection, this method offers an alternate treatment option for adult CMT patients with mild symptoms.

Simplified V-Shape Incision Technique for Saving Hair Follicles

BACKGROUND: The scalp is the second most visible part of the anatomy next to the face. Thus, aesthetic considerations such as scars and alopecia are important when planning excision of a mass from the scalp. Aesthetic results have not been satisfactory due to scar widening and hair follicle injury. Many methods have been tried to improve these results, however, they require multiple procedures and longer operation time. METHODS: We evaluated a easy and time-saving V-shape incision for excising a scalp mass. This technique of simplified V-shape incision was performed in 32 patients with benign scalp masses treated from September 2011 to March 2013. The incisions were performed with a blade to make a V-shape margin and preserve deep hair follicles at the flap margins. The defect was closed by approximation of two edges. RESULTS: All tumors were benign and superficial. The size of the scalp masses was 0.4-2.0 cm in width and 1.0-5.0 cm in length. Many hairs from the deep hair follicles grew into the scar, making the scar line almost unnoticeable in all 32 patients. Although some scar widening was evident, the number of hairs per unit was high enough to camouflage the scars. CONCLUSIONS: The simplified V-shape incision was beneficial as a simple, mini-surgical, time-saving procedure. Although the scars were slightly wider, they were covered with penetrating hairs and became unnoticeable.

A Simple Strategy in Avulsion Flap Injury: Prediction of Flap Viability Using Wood's Lamp Illumination and Resurfacing with a Full-thickness Skin Graft

BACKGROUND: Extensive degloving injuries of the extremities usually result in necrosis of the flap, necessitating comprehensive skin grafting. Provided there is a sufficient tool to evaluate flap viability, full-thickness skin can be used from a nonviable avulsed flap. We used a Wood's lamp to determine the viability of avulsed flaps in the operation field after intravenous injection of fluorescein dye. METHODS: We experienced 13 cases during 16 months. Fifteen minutes after the intravenous injection of fluorescein dye, the avulsed skin flaps were examined and non-fluorescent areas were marked under Wood's lamp illumination. The marked area was defatted for full-thickness skin grafting. The fluorescent areas were sutured directly without tension. The non-fluorescent areas were covered by defatted skin. Several days later, there was soft tissue necrosis within the flap area. We measured necrotic area and revised the flap. RESULTS: Among all the cases, necrotic area was 21.3% of the total avulsed area. However, if we exclude three cases, one of a carelessly managed patient and two cases of the flaps were inappropriately applied, good results were obtained, with a necrotic area of only 8.4%. Eight patients needed split-thickness skin grafts, and heel pad reconstruction was performed with free flap. CONCLUSIONS: A full-thickness skin graft from an avulsed flap is a good method for addressing aesthetic concerns without producing donor site morbidity. Fluorescein dye is a useful, simple, and cost-effective tool for evaluating flap viability. Avulsed flap injuries can be managed well with Wood's lamp illumination and a full-thickness skin graft.
