The braincase of Malawisaurus dixeyi (Sauropoda: Titanosauria): A 3D reconstruction of the brain endocast and inner ear.

PLoS One 2019 13;14(2):e0211423. Epub 2019 Feb 13.

Roy M. Huffington Department of Earth Sciences, Southern Methodist University, Dallas, Texas, United States of America.

A braincase of the Cretaceous titanosaurian sauropod Malawisaurus dixeyi, complete except for the olfactory region, was CT scanned and a 3D rendering of the endocast and inner ear was generated. Cranial nerves appear in the same configuration as in other sauropods, including derived features that appear to characterize titanosaurians, specifically, an abducens nerve canal that passes lateral to the pituitary fossa rather than entering it. Furthermore, the hypoglossal nerve exits the skull via a single foramen, consistent with most titanosaurians, while other saurischians, including the basal titanosauriform, Giraffatitan, contain multiple rootlets.

The benefit of trans-attic endoscopic control of ossicular prosthesis after cholesteatoma surgery.

Laryngoscope 2019 Jan 30. Epub 2019 Jan 30.

ENT Department, Hamad Medical Corporation, Doha, Qatar.

Objective: To show the efficiency of using transmastoid atticotomy (TMA) endoscopy on the outcome of ossiculoplasty in patients with cholesteatoma. TMA is often performed as part of the surgical management of patients with middle ear cholesteatoma extending to the epitympanum. TMA can also be used as an access for endoscopic view to confirm the right alignment and stability of the ossicular prosthesis because the reconstruction of the tympanic membrane will obscure the visualization of the prosthesis.

Using a Three-Dimensional Collagen Matrix to Deliver Respiratory Progenitor Cells to Decellularized Trachea In Vivo.

Tissue Eng Part C Methods 2019 Feb;25(2):93-102

1 Lungs for Living Research Centre, UCL Respiratory, Division of Medicine, University College London, London, United Kingdom.

Impact Statement: This article describes a method for engrafting epithelial progenitor cells to a revascularized scaffold in a protective and supportive collagen-rich environment. This method has the potential to overcome two key limitations of existing grafting techniques as epithelial cells are protected from mechanical shear and the relatively hypoxic phase that occurs while grafts revascularize, offering the opportunity to provide epithelial cells to decellularized allografts at the point of implantation. Advances in this area will improve the safety and efficacy of bioengineered organ transplantation. Read More

Correction of Tanzer Type IIB Constricted Ears via Z-shaped Double V-Y Advancement Flaps.

Ann Plast Surg 2019 Mar;82(3):284-288

From the Department of Burn and Plastic Surgery, West China Hospital, Sichuan University, Chengdu, China.

Background: Correction of Tanzer type IIB constricted ears requires sufficient expansion of the auricular skin to cover the reconstructed cartilaginous framework. To obtain an adequately sized skin cover, skin flap transposition from periauricular donor sites has been described; however, it remains challenging to obtain enough skin to enable satisfactory reconstruction. Herein, we describe a novel method that uses 2 local flaps comprising superoauricular, retroauricular, and preauricular soft tissue to expand the skin cover and correct Tanzer type IIB deformity.

Plast Reconstr Surg 2018 Dec 27. Epub 2018 Dec 27.

Division of Plastic and Reconstructive Surgery, Keck School of Medicine of the University of Southern California, Los Angeles, CA Department of Pediatric Plastic Surgery, Wilhelmina Children's Hospital, University Medical Center Utrecht, Heidelberglaan 100 3584 CX Utrecht Cedars Sinai Hospital, Los Angeles, CA Division of Plastic and Reconstructive Surgery, Keck School of Medicine of the University of Southern California, Los Angeles, CA.

Background: The temporoparietal fascia (TPF) flap is frequently used in ear reconstruction. When the TPF is unavailable, options for primary or secondary salvage reconstruction are limited. In these patients, an inferiorly based occipital artery fascia (OCF) transpositional flap is a good alternative for soft tissue coverage over a framework. Read More

Anatomy of the superficial temporal artery in patients with unilateral microtia.

J Plast Reconstr Aesthet Surg 2019 Jan 28;72(1):114-118. Epub 2018 Sep 28.

Lenox Hill Radiology, 61 East 77th Street, Ofc 1, New York, NY 10075, United States.

Background: This retrospective study evaluated the anatomical distribution of the superficial temporal artery (STA) in supply of the temporoparietal fascial (TPF) flap for use in patients with unilateral microtia undergoing reconstruction. We aimed to determine whether embryologic arrest of pharyngeal arch development would lead to aberrant STA, which impedes reliable harvest of the TPF flap in patients requiring microtia repair.

Methods: CT angiograms (CTAs) and 3D reconstruction of the face and neck of 41 patients with microtia, aged 6-21 years, were examined. Read More

Cartilage exposure following autologous microtia reconstruction: An algorithmic treatment approach.

J Plast Reconstr Aesthet Surg 2018 Nov 28. Epub 2018 Nov 28.

Department of Plastic Surgery, Great Ormond Street Hospital for Children NHS Trust, Level 7, Paul O'Gorman Building, Great Ormond Street, London WC1N 3JH, United Kingdom.

Background: Successful reconstruction of microtia involves fabrication of a cartilaginous framework and provision of thin, durable, soft tissue cover. Vascular compromise of this skin envelope can lead to exposure of the underlying cartilage, resulting in cartilage resorption and distortion of the final form of the ear construct. We describe our algorithm for management of this complication. Read More

Skull base reconstruction with pedicled nasoseptal flap: Technique, indications, and limitations.

J Craniomaxillofac Surg 2019 Jan 16;47(1):29-32. Epub 2018 Nov 16.

Neurosurgery, Centre Hospitalier Universitaire de Liège, University of Liège, Liège, Belgium.

Endoscopic skull base surgery allows extensive tumor resection but results in large defects requiring robust dural repair. The vascularized nasal septal flap pedicled on the posterior nasal septal artery is known to have an excellent success rate for dural defect coverage. Detailed step-by-step descriptions of the harvest and placement of this flap are scarce. Read More

The inner ear proteome of fish.

FEBS J 2019 Jan 21;286(1):66-81. Epub 2018 Dec 21.

The Florey Institute of Neuroscience and Mental Health, The University of Melbourne, Parkville, Vic., Australia.

The mechanisms that underpin the formation, growth and composition of otoliths, the biomineralized stones in the inner ear of fish, are largely unknown, as only a few fish inner ear proteins have been reported. Using a partial transcriptome for the inner ear of black bream (Acanthopagrus butcheri), in conjunction with proteomic data, we discovered hundreds of previously unknown proteins in the otolith. This allowed us to develop hypotheses to explain the mechanisms of inorganic material supply and daily formation of growth bands. Read More

Multiple muscular abnormalities in a fetal cadaver with CHARGE syndrome.

Surg Radiol Anat 2018 Nov 21. Epub 2018 Nov 21.

Department of Anatomy, Mersin University Faculty of Medicine, Ciftlikkoy Campus, 33343, Mersin, Turkey.

The CHARGE syndrome characterized by coloboma, heart defects, atresia of the choanae, retarded growth, genitourinary hypoplasia, and ear anomalies is one of the rare syndromes. Although certain clinical issues (scapular winging, sloping shoulder, Sprengel's deformity, kyphosis and scoliosis) which could be related to abnormalities in musculoskeletal structures of the neck and shoulder have been identified in CHARGE syndrome, data on details of muscle anomalies seem to be quite limited in the literature. In this case report, bilateral multiple muscular abnormalities (agenesis of the trapezius, presence of the rhombo-atloid muscle, and presence of the bipartite rhomboid minor with superficial and deep parts) was presented in a fetus cadaver with atypical CHARGE syndrome to attract the attention of clinicians for definitive diagnoses and surgical reconstruction of the shoulders deformity such as scapular winging and Sprengel's deformity.
