After tooth extraction, alveolar bone is resorbed over time. Loss of alveolar bone and reduction of upper soft tissue poses difficulties in future implant placement and long-term survival of the implant. This case report focuses on increasing the soft and hard tissues at the implant placement site by using alveolar ridge augmentation and a xenogeneic collagen matrix as a soft tissue substitute in an extraction socket affected by periodontal disease. In each case, the width of the alveolar bone increased to 6 mm, 8 mm, and 4 mm, and regeneration of the interdental papilla around the implant was shown, as well as buccal keratinized gingiva of 4 mm, 6 mm, and 4 mm, respectively. Enlarged alveolar bone facilitates implant surgery, and interdental papillae and keratinized gingiva enable aesthetic prosthesis. This study performed alveolar ridge augmentation on patients with extraction sockets affected by periodontal disease and additionally used soft tissue substitutes to provide a better environment for implant placement and have positive effects for aesthetic and predictive implant surgery.

Musculoskeletal ultrasound (MSUS) has newly evolved by the mechanical improvement of the machine over past several years, becoming a part of imaging techniques for the evaluation of variable diseases in the musculoskeletal system. MSUS has proven diagnostic superiority in pathologies including rotator cuff disease of the shoulder, lateral epicondylitis of the elbow, diseases of the peripheral nerve, detection of intra-articular loose bodies and soft tissue foreign bodies, and in evaluating small superficial soft tissue tumors such as ganglion, epidermoid cyst, and glomus tumor. Besides, MSUS is very useful for obtaining tissue or fluid via percutaneous fine needle aspiration and/or biopsy for the histopathologic diagnosis. Combining MSUS with MR would play a great role in the field of the diagnostic imaging of the musculoskeletal system. The MSUS examiner should have the knowledge of cross-sectional anatomy, and of the mechanical and physical properties of ultrasound in order to interpret the ultrasound findings accurately and properly, and to avoid diagnostic errors due to variable artifacts subsequently. The goal of this article is to introduce the capabilities of MSUS in certain kinds of clinical situation and to familiarize the reader with MSUS. For the purpose, author intends to describe this article according not to the disease-, or organ-based, but to the clinical problem-based format.

Purpose: "Hallux valgus" is a common disease encountered in clinical practice and is accompanied by foot deformities. Conservative treatment is commonly used in the early stages of hallux valgus. On the other hand, surgical treatment often becomes necessary as the deformity progresses. Surgical treatments involve various osteotomy methods or joint fusion procedures combined with soft tissue release, and outcomes from these surgical treatments are generally favorable. This study compared two soft tissue release techniques in the hallux region. Materials and Methods: This study conducted a retrospective cohort study on 48 participants who underwent surgical treatment for hallux valgus at a single institution from March 1, 2018, to March 31, 2023. A scarf osteotomy was performed in all cases, and the "Modified Mcbride procedure" or "Trans-articular approach" was done for soft tissue release. Hallux valgus angle (HVA), intermetatarsal angle (IMA), and the degree of subluxation of the lateral sesamoid were measured through simple foot radiographs taken before surgery and one year after surgery. Results: In the Modified Mcbride procedure group, HVA, IMA, and the sesamoid position grade decreased from 34.94° to 9.98°, 15.64° to 5.44°, and 2.47 to 0.44, respectively. In the trans-articular approach group, HVA, IMA, and the sesamoid position grade decreased from 33.42° to 7.34°, 15.06° to 6.03°, and 2.17 to 0.58, respectively. There was no significant difference in these changes between the preoperative and one-year postoperative measurements for both techniques (p-value>0.05). Conclusion: A radiological assessment of soft tissue release through the Modified Mcbride procedure and trans-articular approach in hallux valgus did not show significant differences. Therefore, both surgical techniques can be considered in the distal soft tissue release for a hallux valgus correction.

Objective: To evaluate the long term results among patients with soft tissue sarcoma of the thoracic wall. Materials and Methods: Twenty-six patients who were treated with pre-or postoperative radiotherapy between December 1980-December 2007, with a diagnosis of soft tissue sarcoma of the thoracic wall were retrospectively evaluated. Results: The median age was 44 years (14-85 years) and 15 of them were male. A total of 50% of patients were grade 3. The most common histologic type of tumor was undifferentiated pleomorphic sarcoma (26.9%). Tumor size varied between 2-25 cm (median 6.5 cm). Seventeen of the cases had marginal and 9 had wide local resection. Four cases received preoperative radiotherapy and 22 postoperative radiotherapy. Six of the patients with large and high grade tumors received chemotherapy. Median follow-up time was 82 months (9-309 months). Local recurrence and metastasis was detected in 34.6% and 42.3% of patients, respectively. Five-year local control (LC), disease-free survival (DFS), overall survival (OS), and disease-specific survival (DSS) were 62%, 38%, 69%, and 76% respectively. On univariate analysis, the patients with positive surgical margins had a markedly lower 5-year LC rate than patients with negative surgical margin, but the difference was not significant (43% vs 78%, p=0.1). Five-year DFS (66% vs 17%) and DSS (92% vs 60%) rates were significantly worse for the patients who had high grade tumors (p=0.01, p=0.008 respectively). Conclusions: Tumor grade and surgical margin are essential parameters for determining the prognosis of thoracic wall soft tissue sarcoma both in our series and the literature.

Late complications of head and neck cancer survivors include neck muscle atrophy and soft-tissue fibrosis. We present an autopsy case of neck muscle atrophy and soft-tissue fibrosis (sternocleidomastoid, omohyoid, digastric, sternohyoid, sternothyroid, and platysma muscles) within the radiation field after modified radical neck dissection type I and postoperative radiotherapy for floor of mouth cancer. A 70-year-old man underwent primary tumor resection of the left floor of mouth, left marginal mandibulectomy, left modified radical neck dissection type I, and reconstruction with a radial forearm free flap. The patient received adjuvant radiotherapy. The dose to the primary tumor bed and involved neck nodes was 63 Gy in 35 fractions over 7 weeks. Areas of subclinical disease (left lower neck) received 50 Gy in 25 fractions over 5 weeks. Adjuvant chemotherapy was not administered.

The most common cause of treatment failure in oral cavity cancer is when it is found to have local recurrence, usually occurring in the ipsilateral cervical lymph node. On the contrary, it is extremely rare to find local recurrence in soft tissue metastasis (STM) in the contralateral neck. Furthermore, lung cancer and malignant lymphoma are most commonly confined to their primary sites. The poor general condition increases the likelihood of STM, which indicates bad prognosis. A 72-year-old man with a hard and fixed mass on the right submandibular space visited our clinic. He had received a wide excision with local flapreconstruction for squamous cell carcinoma in the left corner of lower lip 18 months ago. We performed the wide excision with bilateral selective neck dissection (I-III), and he was finally diagnosed as STM from contralateral lip cancer. We report this unique and rare disease entity with a literature review.

Purpose: We report the diagnosis, treatment outcomes and prognosis of the patients with soft tissue malignant myoepithelioma in the extremities. Materials and Methods: We retrospectively reviewed 6 patients with soft tissue malignant myoepithelioma in the extremities who were treated at our institution between 2008 and 2014. Two patients received unplanned excision at another hospital and remaining 4 patients underwent the biopsy procedures and received wide excision at our hospital. Results: There were 3 men and 3 women with mean age of 41 (33-54) years. The average follow up was 28 (9-45) months. Among the 6 patients, only 4 patients underwent biopsy procedures under the impression of malignant soft tissue sarcoma. Surgical margins for these 4 patients were negative. Two patients who had unplanned excision received another re-excision and one of them showed no residual tumor in the resected specimen. Local recurrences were developed in all patients and distant metastasis in 4 patients. All 4 patients who developed distant metastasis died due to disease progression. Among the 2 patients who developed local recurrence only, one patient has another local recurrence after re-operation and remaining one patient is no evidence of disease for 2 years after resection of locally recurred mass. Conclusion: Soft tissue malignant myoepithelioma in the extremities is a rare disease and shows an aggressive behavior. Appropriate biopsy under the impression of soft tissue malignancy is necessary and complete surgical resection with wide margins is the recommended treatment of choice.

Background: This study investigated the clinical outcomes of surgical treatment of primary chest wall soft tissue sarcoma (CW-STS). Methods: Thirty-one patients who underwent surgery for CW-STS between 2000 and 2015 were retrospectively reviewed. The disease-free and overall survival rates were estimated using the Kaplan-Meier method, and prognostic factors were analyzed using a Cox proportional hazards model. Results: The median follow-up duration was 65.6 months. The most common histologic type of tumor was malignant fibrous histiocytoma (29%). The resection extended to the soft tissue in 14 patients, while it reached full thickness in 17 patients. Complete resection was achieved in 27 patients (87.1%). There were 5 cases of local recurrence, 3 cases of distant metastasis, and 5 cases of combined recurrence. The 5-year disease-free rate was 49%. Univariate analysis indicated that incomplete resection (p<0.001) and stage (p=0.062) were possible risk factors for recurrence. Multivariate analysis determined that incomplete resection (p=0.013) and stage (p=0.05) were significantly associated with recurrence. The overall 5- and 10-year survival rates were 86.8% and 64.3%, respectively. No prognostic factor for survival was identified. Conclusion: Long-term primary CW-STS surgery outcomes were found to be favorable. Incomplete microscopic resection and stage were risk factors for recurrence.

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.
