Morel-Lavallee lesion (MLL) is a closed degloving injury resulting from blunt shearing or tangential forces. In this condition, hemolymph is collected in the closed space between the separated subcutaneous tissue and the underlying fascia. The clinical manifestation of MLL varies from soft fluctuant swelling to skin necrosis or wound sepsis. Due to its inconsistent clinical manifestations and delayed onset, it is rarely described. We present a case of a 28-month-old child who developed delayed MLL arising from pelvic fracture after a motor vehicle accident. In addition, we provide a review of MLL and describe rare cases of it in children.

Various methods have been introduced to assess the tissue volume because volumetric evaluation is recognized as one of the most important steps in reconstructive surgery. Advanced volume measurement methods proposed recently use three-dimensional images. They are convenient but have drawbacks such as requiring expensive equipment and volume-analysis software. The authors devised a volume measurement method using the Image J software, which is in the public domain and does not require specific devices or software packages. The orbital and breast volumes were measured by our method using Image J data from facial computed tomography (CT) and breast magnetic resonance imaging (MRI). The authors obtained the final volume results, which were similar to the known volume values. The authors propose here a cost-effective, simple, and easily accessible volume measurement method using the Image J software.

The authors' method for preoperatively measuring breast volume on three-dimensional simulated magnetic resonance imaging scans was both efficient and accurate. It would therefore be useful for achieving better aesthetic outcomes of breast reconstruction.

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.

Sebaceous carcinoma is a rare malignant tumor of the skin. Although this tumor is not completely understood due to its rarity and the paucity of published reports, it is known to be an aggressive tumor with a high incidence in Asia. Sebaceous carcinomas occur preferentially in the periocular region and require attention not to miss the associated Muir-Torre syndrome. In the case of localized disease, a wide local excision with clear margin followed by adjuvant radiation therapy is usually considered the standard treatment strategy but there is no agreed treatment strategy or standard chemotherapeutic regimen for recurrent metastatic sebaceous carcinoma. We report here two cases of recurrent metastatic sebaceous carcinoma patients who responded to 5-fluorouracil and cisplatin combination chemotherapy, and review the literature. We suggest that 5-fluorouracil-cisplatin can be considered a feasible and effective treatment modality for recurrent sebaceous carcinoma.

We performed a retrospective review of patients who presented with delayed dystopia as a consequence of an orbital roof defect due to fractures and nontraumatic causes to search for a correlation between orbital roof defect size and surgical indications for the treatment thereof. Retrospective analyses were performed in 7 patients, all of whom presented with delayed dystopia due to orbital roof defects, between January 2001 and June 2011. The causes of orbital roof defects were displaced orbital roof fractures (5 cases), tumor (1 case), and congenital sphenoid dysplasia (1 case). All 7 patients had initially been treated conservatively and later presented with significant dystopia. The sizes of the defects were calculated on computed tomographic scans. Among the 7 patients, aspiration of cerebrospinal fluid, which caused ocular symptoms, in 1 patient with minimal displaced orbital roof and reconstruction with calvarial bone, titanium micromesh, or Medpor in 6 other patients were performed. The minimal size of the orbital roof in patients who underwent orbital roof reconstruction was 1.2 cm (defect height) x 1.0 cm (defect length), 0.94 cm(2). For all patients with orbital dystopia, displacement of the globe was corrected without any complications, regardless of whether the patient was evaluated grossly or by radiology. In this retrospective study, continuous monitoring of clinical signs and active surgical management should be considered for cases in which an orbital roof defect is detected, even if no definite symptoms are noted, to prevent delayed sequelae.
