MR Imaging of the Orbital Apex
J Korean Radiol Soc 2000;4 :26 9-0 6 1 6 MR Imaging of the Orbital Apex: An a to m y and Pat h o l o g y 1 Ho Kyu Lee, M.D., Chang Jin Kim, M.D.2, Hyosook Ahn, M.D.3, Ji Hoon Shin, M.D., Choong Gon Choi, M.D., Dae Chul Suh, M.D. The apex of the orbit is basically formed by the optic canal, the superior orbital fis- su r e , and their contents. Space-occupying lesions in this area can result in clinical d- eficits caused by compression of the optic nerve or extraocular muscles. Even vas c u l a r changes in the cavernous sinus can produce a direct mass effect and affect the orbit ap e x. When pathologic changes in this region is suspected, contrast-enhanced MR imaging with fat saturation is very useful. According to the anatomic regions from which the lesions arise, they can be classi- fied as belonging to one of five groups; lesions of the optic nerve-sheath complex, of the conal and intraconal spaces, of the extraconal space and bony orbit, of the cav- ernous sinus or diffuse. The characteristic MR findings of various orbital lesions will be described in this paper.

The Square Flap Technique for Burn Contractures: Clinical Experience and Analysis of Length Gain
Annals of Burns and Fire Disasters - vol. XXXI - n. 4 - December 2018 THE SQUARE FLAP TECHNIQUE FOR BURN CONTRACTURES: CLINICAL EXPERIENCE AND ANALYSIS OF LENGTH GAIN DOUBLE LAMBEAU RHOMBOÏDE POUR BRIDE SÉQUELLAIRE DE BRÛ- LURE: EXPÉRIENCE PRATIQUE ET ANALYSE DE LA LONGUEUR GAGNÉE Hifny M.A. Department of Plastic Surgery, Faculty of Medicine, Qena University Hospital, South Valley University, Egypt SUMMARY. Post-burn contractures, affecting the joints especially, are demanding problems. Many surgical techniques have been designated for burn contracture release. The aim of this study is to investigate the efficiency of the square flap technique to release a post-burn scar contracture, and assess the post-operative length gain that can be achieved by simple mathematical calculation. In this study, sixteen patients with linear contracture bands were treated with the square flap tech- nique. The anatomical distribution of the contractures was: axilla, cubital fossa, flank, perineum and popliteal fossa. Scar maturity ranged from 4 months - 9 years. Square flap width and contracture band length before and immediately after surgery were recorded by simple mathematical calculation. Flap complication was assessed. Patient satisfaction was also assessed during the follow-up period. All square flaps were effective in lengthening the contracture bands. The length of the contracture that was released ranged from 2 to 6 cm. The gain in length provided with this technique ranged from 212 to 350%, average 247%, and adequate contracture release was achieved in all cases postoperatively. All square flaps healed uneventfully except for one (6%), which demonstrated limited epidermolysis that healed by secondary intention. The fol- low-up interval ranged from 6 months to 1.5 years. -

Unusual Cubital Fossa Anatomy – Case Report
Anatomy Journal of Africa 2 (1): 80-83 (2013) Case Report UNUSUAL CUBITAL FOSSA ANATOMY – CASE REPORT Surekha D Shetty, Satheesha Nayak B, Naveen Kumar, Anitha Guru. Correspondence: Dr. Satheesha Nayak B, Department of Anatomy, Melaka Manipal Medical College (Manipal Campus), Manipal University, Madhav Nagar, Manipal, Karnataka State, India. 576104 Email: [email protected] SUMMARY The median nerve is known to show variations in its origin, course, relations and distribution. But in almost all cases it passes through the cubital fossa. We saw a cubital fossa without a median nerve. The median nerve had a normal course in the upper part of front of the arm but in the distal third of the arm it passed in front of the medial epicondyle of humerus, surrounded by fleshy fibres of pronator teres muscle. Its course and distribution in the forearm was normal. In the same limb, the fleshy fibres of the brachialis muscle directly continued into the forearm as brachioradialis, there being no fibrous septum separating the two muscles from each other. The close relationship of the nerve to the epicondyle might make it vulnerable in the fractures of the epicondyle. The muscle fibres surrounding the nerve might pull up on the nerve and result in altered sensory-motor functions of the hand. Since the brachialis and brachioradialis are two muscles supplied by two different nerves, this continuity of the muscles might result in compression/entrapment of the radial nerve in it. Key words: Median nerve, cubital fossa, brachialis, brachioradialis, entrapment INTRODUCTION The median nerve is the main content of and broad tendon which is inserted into the cubital fossa along with brachial artery and ulnar tuberosity and to a rough surface on the biceps brachii tendon. -
Evisceration, Enucleation and Exenteration
CHAPTER 10 EVISCERATION, ENUCLEATION AND EXENTERATION This chapter describes three operations that either remove the contents of the eye (evisceration), the eye itself (enucleation) or the whole orbital contents (exenteration). Each operation has specific indications which are important to understand. In many cultures the removal of an eye, even if blind, is resisted. If an eye is very painful or grossly disfigured an operation will be accepted more readily. However, if the eye looks normal the patient or their family may be very reluctant to accept its removal. Therefore tact, compassion and patience are needed when recommending these operations. ENUCLEATION AND EVISCERATION There are several reasons why either of these destructive operations may be necessary: 1. Malignant tumours in the eye. In the case of a malignant tumour or suspected malignant tumour the eye should be removed by enucleation and not evisceration.There are two important intraocular tumours, retinoblastoma and melanoma and for both of them the basic treatment is enucleation. Retinoblastoma is a relatively common tumour in early childhood. At first the growth is confined to the eye. Enucleation must be carried out at this stage and will probably save the child’s life. It is vital not to delay or postpone surgery. If a child under 6 has a blind eye and the possibility of a tumour cannot be ruled out, it is best to remove the eye. Always examine the other eye very carefully under anaesthetic as well. It may contain an early retinoblastoma which could be treatable and still save the eye. Retinoblastoma spreads along the optic nerve to the brain. -

K.V 2. *1 Assistant Professor, Department Of Anatomy,Sri Devaraj Urs Medical College ,Tamaka, Kolar, Karnataka, India. 2 Professor And Head, Department Of Anatomy ,Sri Devaraj Urs Medical College, Tamaka, Kolar, India. ABSTRACT Introduction: Foramen ovale is an important foramen in the middle cranial fossa. Foramen ovale is situated in the greater wing of sphenoid bone, posterior to the foramen rotandum. Through the foramen ovale the mandibular nerve, accessory meningeal artery, lesser petrosal nerve, emissary veins pass .The shape of the foramen ovale is usually oval compared to other foramen of the skull. Materials and Methods: The study was conducted on 55 dry human skulls(110 sides) in Department of Anatomy, Sri Devaraj Urs Medical college, Tamaka, Kolar. Skulls in poor condition or skulls with partially damaged surroundings around the foramen ovale were excluded from the study. Linear measurements were taken on right and left sides of foramen ovale using divider and meter rule. Results: The maximum length of foramen ovale was 14 mm on the right side and 17 mm on the left, its maximum breadth on the right side was 8mm and 10mm on the left . Through the statistical analysis of morphometric measurements between right and left foramen ovale which was found to be insignificant , the results of both sides marks as the evidence of asymmetry in the morphometry of the foramen ovale. -
Comprehensive Review of the Superficial Veins of the Forearm from a Historical, Anatomical and Clinical Point of View
IJAE Vol. 124, n. 2: 142-152, 2019 ITALIAN JOURNAL OF ANATOMY AND EMBRYOLOGY Circulatory system Comprehensive review of the superficial veins of the forearm from a historical, anatomical and clinical point of view Lucas Alves Sarmento Pires1,2,*, Albino Fonseca Junior1,2, Jorge Henrique Martins Manaia1,2, Tulio Fabiano Oliveira Leite3, Marcio Antonio Babinski1,2, Carlos Alberto Araujo Chagas2 1 Medical Sciences Post Graduation Program, Fluminense Federal University, Niterói, Rio de Janeiro, Brazil 2 Morphology Department, Fluminense Federal University, Niterói, Rio de Janeiro, Brazil 3 Interventional Radiology Unit, Radiology Institute, University of São Paulo Medical School, São Paulo, Brazil Abstract The superficial veins of the forearm are prone to possess different patterns of anastomosis. This is highly significant, as venipunctures in the upper limb are among the most performed procedures in the world and they often rely on the veins of the cubital fossa. In addition, the relationship of these veins to the cutaneous nerves are also prone to vary and are often uncer- tain. These veins are also manipulated in the creation of arteriovenous fistula for dialisis, which remains as the best choice of treatment for renal failure patients. Such fistulas are often per- formed on the wrist or the cubital fossa, with the cephalic vein or basilic vein. It is known that anatomical variations of the vessels and nerves on the cubital fossa may induce the profession- als to error, and one of the most common complications of venipuncture are accidental nerve puncture, which can lead to paresthesia and pain. We aim to perform a comprehensive review of the venous arrangements of the cubital fossa and their clinical aspects, as well as of veni- puncture from a historical perspective and of the complications of venipuncture and arterio- venous fistula from an anatomical point of view, with the purpose of compiling available data and help healthcare professionals to reduce puncture errors or arteriovenous fistula complica- tions and improve patient care.
