Background: Reconstruction of congenital microtia remains challenging, particularly in patients with a history of ear canaloplasty due to insufficient regional soft tissue. The insertion of a tissue expander prior to implantation of the cartilage framework has traditionally been employed. However, this procedure could induce additional morbidity. Herein, we present a method using V-Y advancement of a temporal triangular flap to gain additional soft tissue in these challenging cases. Methods: Congenital microtia patients with a history of ear canaloplasty who underwent auricular reconstruction using the Nagata technique between 2016 and 2020 were reviewed. To obtain additional soft tissue, V-Y advancement of a temporal triangular flap was performed concurrently with implantation of the costal cartilage framework, without prior insertion of a tissue expander. The outcomes of these patients with respect to postoperative complications and esthetics were evaluated. Results: Eight patients with bilateral lesions were included. No specific complications developed after the first-stage surgery. However, one patient experienced complications after the second stage (auricular elevation). An analysis of the esthetic results showed most patients had excellent outcomes, achieving a satisfactory convolution. The median number of operations needed to complete reconstruction was 2, which was fewer than required using the conventional method with prior insertion of a tissue expander. Conclusions In patients with a history of previous canaloplasty, V-Y advancement of a temporal triangular flap could serve as an alternative to tissue expansion for microtia reconstruction. This technique provided reliable and satisfactory results with a reduced number of surgical stages.

BACKGROUND: CGCryoDerm was first introduced in 2010 and offers a different matrix preservation processes for freezing without drying preparation. From a theoretical perspective, CGCryoDerm has a more preserved dermal structure and more abundant growth factors for angiogenesis and recellularization. In the current study, the authors performed a retrospective study to evaluate freezing- and freeze-drying-processed acellular dermal matrix (ADM) to determine whether any differences were present in an early complication profile. METHODS: Patients who underwent ADM-assisted tissue expander placement for two stage breast reconstruction between January of 2013 and March of 2014 were retrospectively reviewed and divided into two groups based on the types of ADM-assisted expander reconstruction (CGDerm vs. CGCryoDerm). Complications were divided into four main categories and recorded as follows: seroma, hematoma, infection, and mastectomy skin flap necrosis. RESULTS: In a total of 82 consecutive patients, the CGCryoDerm group had lower rates of seroma when compared to the CGDerm group without statistical significance (3.0% vs. 10.2%, P=0.221), respectively. Other complications were similar in both groups. Reconstructions with CGCryoDerm were found to have a significantly longer period of drainage when compared to reconstructions with CGDerm (11.91 days vs. 10.41 days, P=0.043). CONCLUSIONS: Preliminary findings indicate no significant differences in early complications between implant/expander-based reconstructions using CGCryoderm and those using CGDerm.

BACKGROUND: Non-incisional blepharoplasty is a simple, less invasive method for creating a more natural-appearing double eyelid than classical incisional blepharoplasty. However, in aging patients, non-incisional blepharoplasty is not effective due to more severe blepharochalasis. Traditionally, incisional blepharoplasty is a common surgical method used for older patients, but blepharoplasty in elderly patients typically results in prolonged recovery times, and final blepharoplasty lines may be located in unintended or asymmetrical positions. Here, we introduce a new modified combination technique for geriatric blepharoplasty. METHODS: A total of ten patients were treated from July 2010 through July 2012 using the combination method. First, we performed non-incisional blepharoplasty using tarsodermal fixation. Then, incisional blepharoplasty with additional elliptical excision of the upper eyelid skin was performed. We removed pretarsal tissue, fat, the orbicularis oculi muscle, and orbital fat. Telephone surveys were administered to all patients for follow-up. The questionnaire was composed of eight questions that addressed recurrence and satisfaction with aesthetics and the procedure. RESULTS: A total of nine patients (90%) responded to the telephone survey. All cases of moderate to severe blepharochalasia were corrected and there were no major complications. Patients who underwent blepharoplasty had higher satisfaction scores. All patients were satisfied with the postoperative shapes of their eyelids. CONCLUSIONS: The advantages of the proposed technique include: ease of obtaining a natural-looking fold with symmetry at the desired point; reproducible methods that require short operation times; fast postoperative recovery that results in a natural-appearing double-eyelid line; and high patient satisfaction.

BACKGROUND: Infants with deformational plagiocephaly (DP) usually present with cranial vault deformities as well as facial asymmetry. The purpose of this study was to use three-dimensional anthropometric data to evaluate the influence of cranial deformities on facial asymmetry. METHODS: We analyzed three-dimensional computed tomography data for infants with DP (n=48) and without DP (n=30, control). Using 16 landmarks and 3 reference planes, 22 distance parameters and 2 angular parameters were compared. This cephalometric assessment focused on asymmetry of the orbits, nose, ears, maxilla, and mandible. We then assessed the correlation between 23 of the measurements and cranial vault asymmetry (CVA) for statistical significance using relative differences and correlation analysis. RESULTS: With the exception of few orbital asymmetry variables, most measurements indicated that the facial asymmetry was greater in infants with DP. Mandibular and nasal asymmetry was correlated highly with severity of CVA. Shortening of the ipsilateral mandibular body was particularly significant. There was no significant deformity in the maxilla or ear. CONCLUSION: This study demonstrated that the cranial vault deformity in DP is associated with facial asymmetry. Compared with the control group, the infants with DP were found to have prominent asymmetry of the nose and mandible.

Unilateral nostril hypoplasia is an extremely rare congenital malformation of unknown etiology, and only a few cases have been reported in literature. Owing to variability and complexity of the deformity, surgical correction of unilateral nostril hypoplasia represents one of the most significant reconstructive challenges to reconstructive plastic surgeons. We report a 7-year-old Vietnamese child with nasal and periocular deformity resembling a craniofacial cleft. Grossly, the right nostril was patent but with alar rim deformity, and the left nostril was not readily identifiable. A dystopic medial canthus was present on the left side as well. Closer inspection and palpation of the left side of nose revealed a patency through the soft tissue and underlying bony structure, Thus, a new alar rim were reconstructed with an irregularly shaped Z-plasty to create patency on the involved side. Simulatneously, a second Z-plasty was performed to address the medial canthal deformity. Postoperative appearance and function was sastisfactory at one-year follow up visit. In the treatment of patients with nostril hypoplasia, a careful preoperative physical examination is a prerequisite, and Z-plasty can be a valuable option for surgical correction.

BACKGROUND: Studies on factors which may predict the risk of diabetes are scarce. This prospective cohort study was conducted to determine the association between adiponectin and type 2 diabetes among Korean men and women. METHODS: A total of 42,845 participants who visited one of seven health examination centers located in Seoul and Gyeonggi province, Republic of Korea between 2004 and 2008 were included in this study. The incidence rates of diabetes were determined through December 2011. To evaluate the effects of adiponectin on type 2 diabetes, the Cox proportional hazard model was used. RESULTS: Of the 40,005 participants, 959 developed type 2 diabetes during a 6-year follow-up. After the adjustment for age, body mass index (BMI), and waist circumference, the risks for type 2 diabetes in participants with normoglycemia had a 1.70-fold (95% confidence interval [CI], 1.21 to 2.38) increase in men and a 1.83-fold (95% CI, 1.17 to 2.86) increase in women with the lowest tertile of adiponectin when compared to the highest tertile of adiponectin. For participants with impaired fasting glucose (IFG), the risk for type 2 diabetes had a 1.46-fold (95% CI, 1.17 to 1.83) increase in men and a 2.52-fold (95% CI, 1.57 to 4.06) increase in women with the lowest tertile of adiponectin. Except for female participants with normoglycemia, all the risks remained significant after the adjustment for fasting glucose and other confounding variables. Surprisingly, BMI and waist circumference were not predictors of type 2 diabetes in men or women with IFG after adjustment for fasting glucose and other confounders. CONCLUSION: A strong association between adiponectin and diabetes was observed. The use of adiponectin as a predictor of type 2 diabetes is considered to be useful.
