Spring-mediated cranial vault expansion (SMC) has become a primary treatment modality at our institution to correct scaphocephalic head shape in the setting of isolated sagittal craniosynostosis (CS). Spring-mediated cranioplasty is associated with minimal procedural morbidity and reliable clinical efficacy, although long-term outcomes are not well elucidated. Herein we describe our institutional experience and lessons learned with SMC. We hypothesize that SMC performed in young infants offers durable...

Soft-tissue contour deficiencies depend on various origins including esthetics, congenital and post trauma asymmetries, post tumor defects, and chronic wound sequelae. Reconstructions or repairs are still a challenge today. Fat grafting is an old reconstructive technique dating back to 1893, but it has only recently become popular, especially among plastic surgeons. Being generally disregarded by medical practitioners for many years, adipose tissue has come into the spotlight because it is omnipresent...

Correct anatomical reconstruction of the orbital wall for function and cosmesis is important; however, this is difficult because of the structure's complexity. The authors aimed to analyze and classify orbital morphology from computed tomography (CT) images and examine the relationship between orbital morphology and eyelid morphology in the Japanese population. CT images of 60 men (right side, 29; left side, 31) and 44 women (each side, 22) were included. The lengths of the orbital medial wall and...

Anomalous venous connections between the extracranial and intracranial systems are relatively rare. These connections are also known as sinus pericranii (SP) have been reported previously in the setting of various cranial malformations including craniosynostosis. Angiography may be useful in the diagnosis of SP also allowing for differentiation of the dominance of the venous systems. Several methods have been described in the treatment of SP. In isolated cases both endovascular and open approaches...

The aim of this study was to evaluate the effectiveness of intra-articular injection of liquid platelet-rich fibrin (I-PRF) versus hyaluronic acid (HA) following arthrocentesis in patients suffering from temporomandibular joint (TMJ) pain and dysfunction. A total of 69 patients with internal TMJ derangement were enrolled in this retrospective, matched cohort study. A total of 47 included patients (67 joints) were divided into 3 groups as follows: 16 participants in the arthrocentesis-only group;...

Mixed tumor of the skin (MTS) is a rare skin adnexal neoplasm occurring in sweat glands. It is usually benign, measures 0.5 to 3 cm, and presents as a slowly growing, painless, firm nodule commonly in the head and neck regions. Owing to its rarity and lack of distinctive clinical manifestations, confirmative diagnosis is made on the basis of its pathologic features. Malignant MTS also develops de novo or from preexisting benign MTS even though they occur rarely. It should be excised completely to...

Objective: Tumors in the deep infratentorial region can be accessed via the supracerebellar-infratentorial (SCIT) or suboccipital-transcerebellar (SOTC) approaches in the sitting or prone position. Diagnosis of tumors in this region and review of their therapies are inseparably connected with cranial tomographic imaging. We retrospectively evaluate a cohort of patients who underwent tumor resection in this region and correlate complication rates to the literature, and evaluate the potential influence...

The cervicofacial flap is a workhorse flap for reconstruction of moderate to large sized defects of the cheek. Defects that involve the eyelid-cheek junction are often the most challenging of these. While the ideal plane of dissection has been debated, it is our belief that dissection in the sub-superficial musculo-aponeurotic system (SMAS) plane provides better aesthetic and functional outcomes due to enhanced vascularity, fascial support, and additional bulk of the flap itself. The authors present...

Various resorbable plates and screws were used for facial bone fractures because of several strengths. However, there are few studies on their clinical course and long-term follow-up concerning their degradation and resorption time. The authors present rare case of long term follow-up of resorbable plates and screws under the incision site.

A 52-year-old, alcohol-intoxicated woman suffered periorbital trauma to the left eye and presented to the emergency department with proptosis and complaints of decreased vision in the left eye. Physical examination revealed loss of light perception (LP), relative afferent pupillary defect (RAPD), pupil dilatation, and corneal epithelial defect of the left eye. In addition, the fundus of the left eye was not easily visible due to severe corneal abrasion and edema, but there was no retinal detachment...

Introduction: Posterior distraction is the preferred surgical treatment for particularly Apert and Crouzon syndrome in most craniofacial centers, using either external distractors or springs. The authors prefer the use of springs and have adapted their technique to further improve outcomes. Methods: All patients who were treated with the adapted technique for occipital expansion using springs were included. The most significant adaption that the authors introduced in 2017 is using a bony...

Abstract Phenotypic polymorphisms are common in nature, but the mechanism through which natural selection maintains them can be difficult to identify. Heterozygote advantage, negative frequency-dependent selection, and variation in selective environment each can explain polymorphisms in some systems. Although first observed nearly 100 years ago, the egg mass color polymorphism in the spotted salamander (Ambystoma maculatum) still is not well understood. Females of this species...

As early as December 2019 in the province of Hubei, China, contamination of patients with pneumonia of an unknown etiology occurred. These patients presented with symptoms such as coughing, sore throat, malaise, diarrhea, high fever, and dyspnea. This emerging disease was named COVID-19 due to being part of the group of coronaviruses (CoVs) belonging to the subfamily Orthocoronavirinae, in the Coronaviridae family and in the Nidovirales order. COVID-19 is most commonly transmitted through speech,...

Protein-protein interactions between virus and host are crucial for infection. SARS-CoV-2, the causative agent of COVID-19 pandemic is an RNA virus prone to mutations. Formation of a stable binding interface between the Spike (S) protein Receptor Binding Domain (RBD) of SARS-CoV-2 and Angiotensin-Converting Enzyme 2 (ACE2) of host actuates viral entry. Yet, how this binding interface evolves as virus acquires mutations during pandemic remains elusive. Here, using a high fidelity bioinformatics pipeline,...

Abstract In March 2020, the New York City metropolitan area became the epicenter of the United States’ SARS-CoV-2 pandemic and the surge of new cases threatened to overwhelm the area’s hospital systems. This article describes how an anesthesiology department at a large urban academic hospital rapidly adapted and deployed to meet the threat head-on. Topics included are preparatory efforts, development of a team-based staffing model, and a new strategy for resource management. While...

Female physicians represent a growing share of the medical workforce and may have better patient outcomes than male physicians, yet numerous studies have shown that they earn 8 to 29% less than their male counterparts. The magnitude of and reasons for this pay gap are still debated. There are clear…
