Fabrication of 3D Models for Microtia Reconstruction Using Smartphone-Based Technology.

Ann Otol Rhinol Laryngol 2021 Jun 10:34894211024051. Epub 2021 Jun 10.

Baylor College of Medicine Department of Otolaryngology-Head and Neck Surgery, Texas Children's Hospital Department of Surgery, Houston, TX, USA.

Objective: Microtia reconstruction is technically challenging due to the intricate contours of the ear. It is common practice to use a two-dimensional tracing of the patient's normal ear as a template for the reconstruction of the affected side. Recent advances in three-dimensional (3D) surface scanning and printing have expanded the ability to create surgical models preoperatively. Read More

Auricular reconstruction after Mohs micrographic surgery: analysis of 101 cases.

An Bras Dermatol 2021 Jun 2. Epub 2021 Jun 2.

Dermatology Service, Hospital de Clínicas, Universidade Federal do Paraná, Curitiba, PR, Brazil; Postgraduate Program in Internal Medicine and Health Sciences, Universidade Federal do Paraná, Curitiba, PR, Brazil; Private Practice, Curitiba, PR, Brazil.

Background: The ear is a region that has a high prevalence of cutaneous carcinomas and several guidelines indicate Mohs micrographic surgery as the first-choice treatment in such cases. Although the technique allows maximum preservation of healthy tissue, many auricular surgical wounds constitute a challenge due to the peculiar local anatomy, with evident curves and reliefs. Auricular reconstruction should prioritize function before aesthetics, but without leaving the latter aside, since postoperative distortions can have a significant psychological impact. Read More

Ear Nose Throat J 2021 May 26:1455613211016721. Epub 2021 May 26.

42709Fundación Universitaria de Ciencias de la Salud (FUCS), Hospital San José, Bogotá, Colombia.

Angiolymphoid hyperplasia (AH) was first described by Wells and Whimster in 1969 as a benign vasoproliferative pathology with a varied infiltrate of eosinophils, lymphocytes, and plasmatic cells. Clinical presentation has been described in the literature as small red-bluish nodules, less than 3 cm in diameter that can bleed in 25% of the cases and be pruritic and painful in 37% and 20% of the cases, respectively. Particularly, AH can appear in the ear; nevertheless, other regions have been affected, including the scalp, lips, tongue, orbit, muscle, and bone. Read More

Plast Reconstr Surg Glob Open 2021 May 21;9(5):e3592. Epub 2021 May 21.

Creighton University School of Medicine, Omaha, Neb.

This article describes a unique approach for reconstruction of large helical rim defects. By raising bilateral chondrocutaneous flaps of the helical rim while including a semicircular chondrocutaneous excision of the adjacent scapha and antihelix, large defects can be repaired with minimal loss to the overall external ear circumference. This is a technically simple and reliable method that has resulted in excellent cosmetic outcomes and minimal morbidity in our practice. Read More

Sci Rep 2021 May 18;11(1):10545. Epub 2021 May 18.

Department of Obstetrics and Gynecology, Hospital de la Santa Creu i Sant Pau, Universitat Autònoma de Barcelona, Carrer Sant Quintí, 89, 08041, Barcelona, Spain.

The aims of this study were to evaluate the feasibility of the New Zealand White (NZW) rabbit for studying implanted biomaterials in pelvic reconstructive surgery; and to compare the occurrence of graft-related complications of a commercial polypropylene (PP) mesh and new developed human dermal matrix implanted at vaginal and abdominal level. 20 white female NZW rabbits were randomized into two groups, experimental group (human acellular dermal matrices-hADM-graft) and control group (commercial PP graft). In each animal, grafts were surgically implanted subcutaneously in the abdominal wall and in the vaginal submucosa layer for 180 days. Read More

Genomic reconstruction of fossil and living microorganisms in ancient Siberian permafrost.

Microbiome 2021 05 17;9(1):110. Epub 2021 May 17.

Princeton University, B88, Guyot Hall, Princeton, NJ, 08544, USA.

Background: Total DNA (intracellular, iDNA and extracellular, eDNA) from ancient permafrost records the mixed genetic repository of the past and present microbial populations through geological time. Given the exceptional preservation of eDNA under perennial frozen conditions, typical metagenomic sequencing of total DNA precludes the discrimination between fossil and living microorganisms in ancient cryogenic environments. DNA repair protocols were combined with high throughput sequencing (HTS) of separate iDNA and eDNA fraction to reconstruct metagenome-assembled genomes (MAGs) from ancient microbial DNA entrapped in Siberian coastal permafrost.

Automatic Detection of Fiducial Landmarks Toward the Development of an Application for Digitizing the Locations of EEG Electrodes: Occipital Structure Sensor-Based Work.

Front Neurosci 2021 29;15:526257. Epub 2021 Apr 29.

The Clinical Hospital of Chengdu Brain Sciences, University of Electronic Science and Technology of China, Chengdu, China.

The reconstruction of electrophysiological sources within the brain is sensitive to the constructed head model, which depends on the positioning accuracy of anatomical landmarks known as fiducials. In this work, we propose an algorithm for the automatic detection of fiducial landmarks of EEG electrodes on the 3D human head model. Our proposal combines a dimensional reduction approach with a perspective projection from 3D to 2D object space; the eye and ear automatic detection in a 2D face image by two cascades of classifiers and geometric transformations to obtain 3D spatial coordinates of the landmarks and to generate the head coordinate system, This is accomplished by considering the characteristics of the scanner information.

Self-position awareness based presence and interaction in virtual reality.

Virtual Real 2020 Jun 31;24:255-262. Epub 2019 Jul 31.

The Schepens Eye Research Institute, Massachusetts Eye and Ear, Department of Ophthalmology, Harvard Medical School, USA.

The awareness of self-position, which refers to the location of our cyclopean eye, is essential to the experience of being immersed and for interacting with a virtual environment. Currently, individual variability in the cyclopean eye location is not considered when presenting virtual reality (VR) content. The effect of the cyclopean eye shift was analyzed with theoretical and experimental methods, and it was found that human vision is sensitive to the visual direction offset caused by the cyclopean eye shift.

Effect of a boomerang-shaped Conchal cartilage graft for Type three Tympanoplasty on Hearing.

Int Arch Otorhinolaryngol 2021 Apr 30;25(2):e289-e295. Epub 2020 Jun 30.

Department of Ear, Nose and Throat, Jawaharlal Institute of Postgraduate Medical Education and Research, Pondicherry, India.

 Chronic suppurative otitis media atticoantral disease (CSOM-AAD) is often associated with ossicular erosion resulting in significant hearing loss. Absence of the stapes suprastructure is a poor prognostic indicator of hearing outcome, which necessitates an effective reconstruction technique for ossicular continuity and restoration of middle ear volume. In the present study, we used a boomerang-shaped conchal cartilage graft. Read More

Rambam Maimonides Med J 2021 Apr 29;12(2). Epub 2021 Apr 29.

Department of Otolaryngology-Head and Neck Surgery, Rambam Health Care Campus, Haifa, Israel.

Introduction: Endoscopic endonasal transsphenoidal surgery (EETS) on the pituitary gland is considered safe and efficacious. The nasoseptal flap (NSF) is sometimes used to prevent or repair postoperative cerebrospinal fluid (CSF) leaks. Few investigators have quantified long-term quality-of-life (QOL) outcomes regarding sinonasal measures after EETS, with or without involvement of the NSF. Read More
