Reconstruction of temporal hollowing deformities using silicone implants made using a toy-clay model: a report of three cases.

Severe temporal hollowing deformities can occur in patients who undergo craniectomy after intracranial hemorrhage. Reconstruction surgery for cosmetic purposes using silicone implants in patients with temporal hollowing deformities after craniectomy is advantageous because the procedure is simple and rapid, with a short recovery time, resulting in lower overall treatment costs. Of paramount importance, this option yields highly satisfactory results for patients.

Analysis and Guidelines for Revisional Malarplasty; Most Common Facial Skeletal Contouring Surgery.

Background: Revisional malarplasty is the most frequently performed and difficult to perform revision surgery among facial contouring surgeries. The incidence of postoperative complications and need for revision surgery is increasing because of indiscriminate malar reduction through a narrow surgical space. The authors analyzed cases of revisional malarplasty secondary to complications.

Volumetric change of the latissimus dorsi muscle after postoperative chemotherapy and radiotherapy in immediate breast reconstruction with an extended latissimus dorsi musculocutaneous flap: final results from serial studies.

Background: Breast reconstruction using an extended latissimus dorsi (eLD) flap can supplement more volume than reconstruction using various local flaps after partial mastectomy, and it is a valuable surgical method since the reconstruction area is not limited. However, when performing reconstruction, the surgeon should consider latissimus dorsi (LD) volume reduction due to postoperative chemotherapy (POCTx) and postoperative radiotherapy (PORTx). To evaluate the effect of POCTx and PORTx on LD volume reduction, the effects of each therapy-both separately and jointly-need to be demonstrated.

The relationship between lymphedema severity and awareness of lymphedema surgery.

Background: During the early stages of lymphedema, active physiologic surgical treatment can be applied. However, lymphedema patients often have limited knowledge and misconceptions regarding lymphedema and surgical treatment. We analyzed the correlations between lymphedema severity and surgical technique according to patients' awareness of surgical treatment for secondary upper extremity lymphedema (UEL).

Pattern of local recurrence after mastectomy and reconstruction in breast cancer patients: a systematic review.

Background: This study aimed to describe the locations of local recurrences based on the mastectomy and reconstruction type in breast cancer patients.

Methods: In November 2020, a systematic literature review was performed through MEDLINE/PubMed and the Cochrane Centre Register of Controlled Trials. Publications that included skin-sparing or nipple-sparing mastectomy followed by breast reconstruction and described the location of local recurrences were analyzed.

Comparison of breast volume change between oncoplastic breast-conserving surgery with radiation therapy and a simultaneous contralateral balancing procedure through the inverted-T scar technique.

Background: Reduction mammoplasty or mastopexy is performed as an additional balancing procedure in patients with large or ptotic breasts who undergo breast-conserving surgery (BCS). Radiation therapy on breasts that have undergone surgery may result in changes in the volume. This study presents a comparative analysis of patients who received post-BCS balancing procedures to determine whether volume changes were larger in breasts that received radiation therapy than on the contralateral side.

Recurrent late seroma after immediate breast reconstruction with latissimus dorsi musculocutaneous flap.

The latissimus dorsi musculocutaneous flap (LDMCF) is widely used for breast reconstruction. However, it has the disadvantage of frequent seroma formation at the donor site, and late seroma has also been reported. The authors report histological findings after the surgical treatment of a late, repeatedly recurrent seroma at 10 years after breast reconstruction with LDMCF.

Attachment distribution of pectoral muscle origins identified in dual-plane breast implant insertion.

Background: Implant-based dual-plane augmentation mammoplasty requires accurate separation of the pectoralis major muscle (PMM) at its origins. The authors identified the PMM origins during breast reconstruction surgery with the goal of providing additional information on subpectoral implant insertion for reconstructive or aesthetic purposes.

Methods: This study was conducted on 67 patients who underwent breast reconstruction surgery at the breast center of our hospital between November 2016 and June 2018.

Volumetric change of the latissimus dorsi muscle after postoperative radiotherapy in immediate breast reconstruction with an extended latissimus dorsi musculocutaneous flap.

Background: This study aimed to determine the magnitude of volume reduction of the latissimus dorsi (LD) muscle after treatment using only postoperative radiotherapy (PORTx) in patients who underwent immediate breast reconstruction using an extended LD musculocutaneous (eLDMC) flap after partial mastectomy.

Methods: We retrospectively reviewed 28 patients who underwent partial mastectomy and an eLDMC flap, received only PORTx, and underwent chest computed tomography (CT) 7 to 10 days after surgery and 18±4 months after the end of radiotherapy, from March 2011 to June 2016. The motor nerve to the LD was resected in all patients.

Adequacy of sentinel lymph node biopsy in malignant melanoma of the trunk and extremities: Clinical observations regarding prognosis.

Background: METHODS for identifying local lymph node metastasis in malignant melanoma include sentinel lymph node biopsy (SLNB) and lymph node dissection (LND). In particular, SLNB has been widely used in recent years. This study aimed to retrospectively confirm the adequacy of the current indication criteria for SLNB by applying those criteria to a mixed group of patients who previously received SLNB and LND.

Role of 18F-Fluorodeoxyglucose Positron Emission Tomography or Positron Emission Tomography/Computed Tomography for the Detection of Recurrent Disease after Treatment of Malignant Melanoma.

Background: The purpose of the current study was to investigate the diagnostic performance of 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET) or PET/computed tomography (PET/CT) for the detection of recurrent disease after treatment of malignant melanoma (MM) through a systematic review and meta-analysis.

Methods: The PubMed and EMBASE databases, from the earliest available date of indexing through December 31, 2018, were searched for studies evaluating the diagnostic performance of 18F-FDG-PET or PET/CT for the detection of recurrent disease after treatment of MM. We determined the sensitivities and specificities across studies, calculated positive and negative likelihood ratios (LR+ and LR-), and constructed summary receiver operating characteristic (SROC) curves.

Volumetric change of the latissimus dorsi muscle after immediate breast reconstruction with an extended latissimus dorsi musculocutaneous flap.

Background: In immediate breast reconstruction using an extended latissimus dorsi musculocutaneous (eLDMC) flap, the volume of the flap decreases, which causes a secondary deformity of the breast shape. Since little research has investigated this decrease in muscle volume, the authors conducted an objective study to characterize the decrease in muscle volume after breast reconstruction using an eLDMC flap.

Methods: Research was conducted from October 2011 to November 2016.

Investigation of the dorsolateral branch of the posterior intercostal artery for use as the pedicle of a free flap: A cadaveric study and case series.

Background: The dorsolateral branch of the posterior intercostal artery (DLBPI) can be easily found while harvesting a latissimus dorsi (LD) musculocutaneous flap for breast reconstruction. However, it remains unknown whether this branch can be used for a free flap and whether this branch alone can provide perfusion to the skin. We examined whether the DLBPI could be reliably found and whether it could provide sufficient perfusion.

Usefulness of the orbicularis oculi myocutaneous flap in periorbital reconstruction.

Background: The esthetic and functional outcomes of periorbital defect reconstruction are very important because of the complex anatomy and specialized functions of this region. The orbicularis oculi myocutaneous (OOMC) flap is useful for the reconstruction of periorbital defects. But, according to the location and depth of the defects, the reconstruction using OMC flaps with various techniques is rare.

A clinical review of reconstructive techniques for patients with multiple skin cancers on the face.

Background: Cases of simultaneous multiple skin cancers in a single patient have become more common. Due to the multiplicity of lesions, reconstruction in such cases is more difficult than after a single lesion is removed. This study presents a series of patients with multiple facial skin cancers, with an analysis of the surgical removal, reconstruction process, and the results observed during follow-up.

The efficacy of elongated axillary incision on extended latissimus dorsi flap for immediate breast reconstruction.

Background: In performing extended latissimus dorsi (ELD) flap procedures, a skin paddle design on the bra line helps reduce visible scarring. This improves the patient's satisfaction with the outcome. However, such a design leads to a longer operation time and increased fatigue of the surgeon due to the narrow operative field.

The Effect of Obesity on the Availabilities of Dopamine and Serotonin Transporters.

The authors investigated relations between obesity, age, and sex and the availabilities of striatal dopamine transporter (DAT) and extrastriatal serotonin transporter (SERT) by I-FP-CIT single-photon emission computed tomography. The study population consisted of 192 healthy controls with screening I-FP-CIT scans. Specific bindings of I-FP-CIT to DAT and SERT were calculated using regions of interest.

Treatment of Nonsyndromic Craniosynostosis Using Multi-Split Osteotomy and Rigid Fixation with Absorbable Plates.

Background: Nonsyndromic craniosynostosis is a relatively common craniofacial anomaly and various techniques were introduced to achieve its operative goals. Authors found that by using smaller bone fragments than that used in conventional cranioplasty, sufficiently rigid bone union and effective regeneration capacity could be achieved with better postoperative outcome, only if their stable fixation was ensured.

Methods: Through bicoronal incisional approach, involved synostotic cranial bone together with its surrounding areas were removed.
