  • Angioleiomyoma is a benign soft tissue tumor originating from vascular smooth muscle. We report a case of a 20-year-old student who presented with pain in the right shoulder of 4 years duration. Shoulder movements were pain-free throughout the range of motion except resisted external rotation. Magnetic resonance imaging visualized a well-circumscribed lesion over the infraspinatus tendon. The lesion was surgically removed and sent for histopathological analysis. Morphology and immunohistochemistry results were suggestive of angioleiomyoma. The most common location for such a lesion is the lower limb, with less than 1% being reported in the upper arm, of which an angioleiomyoma of the shoulder is extremely rare.

  • Post-traumatic enophthalmos and hypoglobus are common sequelae of facial bone fractures, even after reduction surgery. They are associated with functional and esthetic issues, which may lower the quality of life. These deformities frequently present late, and adequate correction is difficult. We report three cases of late inferior orbital rim reconstructions with three-dimensional printed implants to help resolve these problems. The average duration between the traumatic event and surgery was 3 years and 4 months. One patient was treated with a completely absorbable implant and exhibited satisfactory results until the implant started to biodegrade at 1 year and 9 months after surgery. Two patients were treated with a permanent implant and demonstrated satisfactory results. However, longer follow-up periods were needed. There were no complications such as infection, diplopia, or restriction of ocular motion and the patients were satisfied with the esthetic results.

  • Purpose: The axillary web syndrome (AWS) is a selflimiting cause of morbidity in the early postoperative period after axillary surgery. This article presents a rare complication developed after surgical treatment for axillary osmidrosis. Methods: A 55-year-old male patient underwent surgical excision of skin and glandular tissue for axillary osmidrosis. Three weeks after the surgery, he visited our department due to a visible web of left axillary skin overlying palpable cord extends into the medial ipsilateral arm. There was a taut and tender cord of tissue under the skin and shoulder abduction was limited to less than 90 degrees. He was diagnosed with AWS and treated with conservative management. Results: Four months later, AWS resolved completely without any treatment and patient was free of pain or motion restriction. Conculsion: Axillary web syndrome has been described as frequent complication after axillary lymph node dissection or sentinel node biopsy, but not after surgical treatment of axillary osmidrosis. Surgeons must be aware of the risk of axillary web syndrome after treatment of axillary osmidrosis.

  • Perforator free flap (PFF) is currently a major reconstructive option for soft tissue reconstruction in adults. Although PFFs have been used commonly, most reconstructive surgeons still hesitate to perform PFFs in children. The main cause of concern is the perceived high failure rate related to the small diameter of children's perforator vessels. We present 8 consecutive cases of successful transfer of thoracodorsal artery (TDA) & anterolateral thigh (ALT) perforator flap in children. Between 2003 and 2005, 8 children(4 to 13 years old) with soft tissue defects of the extremities were reconstructed with TDA & ALT PFFs. All flaps completely survived. There were no problems relating to vascular spasm or occlusion. Range of motion of reconstructed extremities were fully recovered. Among 8 patients, only 1 patient was performed an additional flap thinning procedure. 8 cases of TDA & ALT perforator flaps were successfully transferred in children. PFF is an excellent option in reconstruction of children as well as in adults because of its thinness, long pedicle length, least donor site morbidity and acceptable donor site scar.

  • The composite anterolateral thigh flap with vascularized fascia lata has emerged as a workhorse at our institution for complex Achilles defects requiring both tendon and soft tissue reconstruction. Safe elevation of this flap, however, is occasionally challenged by absent or inadequate perforators supplying the anterolateral thigh. When discovered intraoperatively, alternative options derived from the same vascular network can be pursued. We present the case of a 74-year-old male who underwent composite Achilles defect reconstruction using a segmental rectus femoris myofascial free flap. Following graduated rehabilitation, postoperatively, the patient resumed full activity and was able to ambulate on his tip-toes. At 1-year follow-up, active total range of motion of the reconstructed ankle exceeded 85% of the unaffected side, and donor site morbidity was negligible. American Orthopaedic Foot and Ankle Society and Short Form-36 scores improved by 78.8% and 28.8%, respectively, compared to preoperative baseline assessments. Based on our findings, we advocate for use of the combined rectus femoris myofascial free flap as a rescue option for reconstructing composite Achilles tendon/posterior leg defects in the setting of inadequate anterolateral thigh perforators. To our knowledge, this is the first report to describe use of this flap for such an indication.

  • Purpose: Soft tissue defect on posterior side of heel exposing Achilles tendon is vulnerable and require thin flap to improve aesthetic and functional results. Reverse superficial sural artery flap is simple and fast procedure, and it can preserves major arteries, supplies reliable constant blood, causes less donor site complication. Authors reviewed our cases and report the clinical results. Materials and Methods: Nine cases of soft tissue defects on the posterior side of heel exposing Achilles tendon were treated with distally based superficial sural artery flap. There were 6 male and 3 female and mean age was 48.4 years. The size of flap was from $4{\times}4cm$ to $10{\times}15cm$ and mean follow-up period was 23 months. Flap survival, postoperative complications were evaluated. Results: All flaps were survived completely without necrosis. There was one case of partial wound dehiscence that needed debridement and repair, and other one case had recurrent discharge that was healed after removal of calcaneal plate. All patient showed acceptable range of ankle motion. Conclusion: Authors suggest that the reverse superficial sural artery flap could be one of the useful treatment options for the soft tissue defect on posterior side of heel exposing Achilles tendon.

  • Sonoelastography is an ultrasound-based technique that visualizes the elastic properties of soft tissues by measuring the tissue motion generated by an externally applied vibration. In this paper. the characteristics of wave generation in soft tissues due to an acoustic vibrator are studied. The effects of modal patterns on the detectability of lesions such as tumors in senoelastography are also investigated These are accomplished by analyzing the vibration patterns calculated using theoretical equations and finite element methods in halt space, infinite plate. and finite-sized tissue. A finite-width source generates shear waves with large amplitude Propagating in specific directions. and the generation characteristics depend both on the width and frequency of the vibrator. as well as the distance from it. It is shown in a finite-sized tissue that the lesion detection in displacement images is quit dependent on the modal patterns inside tissue. In contrast it Is also found that the lesion detectability in strain images is less dependent on the modal Patterns and is much better than that in displacement images.

  • Purpose: To evaluate the results in patients who received total elbow replacement for posttraumatic destroyed or unreduced elbow joint. Materials and Methods: Six patients with posttraumatic destroyed, or unreduced elbow joint, who were nearly impossible to move actively and had pain and grossly unstable joint, were followed up average 42 months. 3 cases were soft tissue injuries and bone defects which were caused by severe comminuted fracture, 1 was a nonunion with comminuted fracture, and 2 were unreduced elbow joint. Total elbow replacement was performed average 10 months after the injury. All the cases were used by semiconstrained prosthesis, and the results were estimated by Mayo elbow perfomance score. Results: Pain was decreased in all the cases postoperatively. Average ranges of motion were improved with active extension 20° and flexion 120°. Mayo elbow performance scores were pain 42.5 points, range of motion 17.5 points, stability 8.3 points, function 19.2 points and totally 87.5 points, and final results were 3 excellent and 3 good. Loosening of prosthesis was not found in all the cases by final follow-up radiograph. Conclusicon: Semiconstrained TER can be used as a effective treatment improving pain and active ranges of motion caused by posttraumatic destroyed or unreduced elbow joint, however, long term follow-up is needed because early loosening of TER can be occurred due to severe bone defects.

  • Purpose: Autologous fat injection into the facial area is a frequently used technique in aesthetic plastic surgery for augmentation of the soft tissue. Fat injection is a very safe procedure because of the advantage of being autologous tissue. Minimal foreign body reaction or infections are noted after fat injection. However, there may be some complications including those as severe as blindness. There have been some case reports on visual disturbances after autologous fat injection reported in the literature. Methods: A 21-year-old female patient underwent autologous fat injection into left eyebrow area to correct depression of soft tissue. Immediately after injection of autologous fat, she complained sudden visual loss on the left eye. She had come to our emergency room and ophthalmologic evaluation showed that the patient could only recognize hand motion. There was no abnormality of the optic nerve on magnetic resonance imaging. Suspecting an ischemic optic neuritis from fat embolism of the central retinal artery, the patient was treated conservatively with occular massage, antiglaucomatic agent, anti-inflammatory drugs and antibiotics. Visual field examination showed visual defect of half the lower hemisphere. Results: While maintaining antiglaucomatic agents and non steroidal anti inflammatory drugs, fundoscopic examination showed no abnormalities on the second day of admission. Visual field examination showed an improvement on the fourth day along with decreased eyeball pain. Significant improvement of vision was noted and the patient was discharged on the fifth day of admission. The patient was followed-up 2 days afterwards with improved vision and visual field defect. Conclusion: We describe an unusual case of sudden unilateral visual disturbance following autologous fat injection into periorbital area.
