M.S Dept of anatomy SIMATS Saveetha dental college, Velappanchavadi Chennai-600095 India Running title: Types of suprameatal spines ABSTRACT: AIM: To identify the occurrence and types of suprameatal spines on either sides of the skull in the suprameatal triangle and to study their clinic implications. OBJECTIVE: To figure out the presence of suprameatal spines in the suprameatal triangle and to review the literature on anatomical and clinic aspects of suprameatal triangle. INTRODUCTION: Suprameatal triangle is present between the posterior wall of external acoustic meatus and posterior root of zygomatic process, in the temporal bone. It is also called as Macewen’s triangle. Suprameatal spine is seen below the upper limit of the orifice of the inner end of external acoustic meatus which is closed by tympanic membrane. It is also called as spine of Henle. RESULT: From the above conducted study, it can be seen that, when the suprameatal spines were evaluated according to its type and occurrence, the crest type of spine present was more than the triangle type. The crest type of spine was found to be 62.2% and the triangle type of spine was about 37.8% CONCLUSION: Thus, this study shows the prevalence of crest and triangle type spine in the dry skulls evaluated.

Abstract In the temporal bone, between the posterior wall of the external acoustic meatus and the posterior root of the zygomatic process is the area called the suprameatal triangle, suprameatal pit, mastoid fossa, foveolasuprameatica, or Mac Ewen's triangle, through which an instrument may be pushed into the mastoid antrum..In the adult, the antrum lies approximately 1.5 to 2 cm deep to the suprameatal triangle. This is an important landmark when performing a cortical mastoidectomy. The triangle lies deep to the cymba conchae.The sex determination of unknown human skulls can be evaluated by using the measurement of the area formed by the xerographic projection of 3craniometric points related to the mastoid process: the porion, asterion, and mastoidale points. Keywords: MacEwen's triangle,mastoidectomy,suprameatal spine,Mastoid antrum ,sex determination,zygomatic process,mastoid process. Introduction MacEwen's triangle is a very important surgical landmark for the mastoid antrum or the largest mastoid air cell.[9] It is also known as Suprameatal triangle or Mastoid fossa.[4] The suprameataltrigone plays a big role in the aspect of clinics.

  • Atlas of the Facial Nerve and Related Structures
    Rhoton Yoshioka Atlas of the Facial Nerve Unique Atlas Opens Window and Related Structures Into Facial Nerve Anatomy… Atlas of the Facial Nerve and Related Structures and Related Nerve Facial of the Atlas “His meticulous methods of anatomical dissection and microsurgical techniques helped transform the primitive specialty of neurosurgery into the magnificent surgical discipline that it is today.”— Nobutaka Yoshioka American Association of Neurological Surgeons. Albert L. Rhoton, Jr. Nobutaka Yoshioka, MD, PhD and Albert L. Rhoton, Jr., MD have created an anatomical atlas of astounding precision. An unparalleled teaching tool, this atlas opens a unique window into the anatomical intricacies of complex facial nerves and related structures. An internationally renowned author, educator, brain anatomist, and neurosurgeon, Dr. Rhoton is regarded by colleagues as one of the fathers of modern microscopic neurosurgery. Dr. Yoshioka, an esteemed craniofacial reconstructive surgeon in Japan, mastered this precise dissection technique while undertaking a fellowship at Dr. Rhoton’s microanatomy lab, writing in the preface that within such precision images lies potential for surgical innovation. Special Features • Exquisite color photographs, prepared from carefully dissected latex injected cadavers, reveal anatomy layer by layer with remarkable detail and clarity • An added highlight, 3-D versions of these extraordinary images, are available online in the Thieme MediaCenter • Major sections include intracranial region and skull, upper facial and midfacial region, and lower facial and posterolateral neck region Organized by region, each layered dissection elucidates specific nerves and structures with pinpoint accuracy, providing the clinician with in-depth anatomical insights. Precise clinical explanations accompany each photograph. In tandem, the images and text provide an excellent foundation for understanding the nerves and structures impacted by neurosurgical-related pathologies as well as other conditions and injuries.

  • 1 Surgical Anatomy Alexander Rauchfuss
    Chapter 1 1 1 Surgical Anatomy Alexander Rauchfuss The temporal bone presents a very complex anatomy. Therefore this overview is restricted to some major points from the viewpoint of surgical anatomy. For more detailed information see “Suggested Reading”. Thetemporalboneaccordingtoitsdevelopmentalanatomyisdivisibleinto four parts: the squamous, mastoid, petrous, and tympanic portions. Points of topographical reference on the lateral surface are the external acoustic meatus with its suprameatal spine, the temporal line, and the mastoid process. Thebaseofthezygomaextendsasacrestposteriorlyandslightlyupward, forming the supramastoid crest or temporal line. The temporal line as a land- mark corresponds to the base of the medial cranial fossa/tegmen tympani, which in most cases of surgery can easily be identified. In combination with the radiological anatomy in a Schüller view it allows adequate planning of the surgical approach to the antrum via the mastoid. All figures show the anatomy of a left ear. 2 1 Surgical Anatomy Figs. 1.1–1.5. Temporal bone and sigmoid sinus Fig. 1.1. Temporal bone. The degree of pneumatization is inconstant. The extent and arrangement of air cells varies considerably from a minimal air cell system in the surroundings of the antrum to involvement of most of the tempo- ral bone. Pneumatization usually begins in late fetal life, progressing until the end of childhood. The pneumatization process starts from the antrum. In most cases one can describe the topography of the cells as follows: periantral, sino- dural, perisinual, perifacial and mastoid tip cells. According to the extension of the cells, there is only one rule: the further from the antrum, the bigger the cells Fig.

  • Analysis of Operating Field Area in Transpyramidal Retrolabyrinthine Approach to Posterior Cranial Fossa
    Folia Morphol. Vol. 61, No. 4, pp. 305–308 Copyright © 2002 Via Medica O R I G I N A L ARTICLE ISSN 0015–5659 www.fm.viamedica.pl Analysis of operating field area in transpyramidal retrolabyrinthine approach to posterior cranial fossa Stanisław Nitek1, Jarosław Wysocki1, Eliza Brożek2 1Department of Normal Anatomy, Medical University of Warsaw, Poland 2Department of Paediatric Otorhinolaryngology, Medical University of Warsaw, Poland [Received 23 September 2002; Revised 21 October 2002; Accepted 21 October 2002] Retrolabyrinthine surgical access to the posterior and middle cranial fossa has a long history of use during the procedures aiming at the removal of small neo- plasmatic changes located in the area of the internal auditory tube. A precise knowledge of the anatomical alterations of the temporal bone in the aspect of the retrolabyrinthine access to the posterior cranial fossa determines a success- ful otoneurosurgical endoscopy, which involves a relatively narrow area. Forty- four cadaver temporal bones of both sexes were measured to obtain the dimen- sions of the surgical area limited by the sigmoid sinus, superior petrosal sinus and posterior labyrinth. The techniques of computer picture analysis were ap- plied in the research. The mean value of the surface area of the figure limited by the sigmoid sinus, superior petrosal sinus and posterior semicircular canal was 175.9 mm² with no significant differences between sexes and sides. The maxi- mal measured value was 356 mm², and the minimal was 84.3 mm². The size of the surgical area is characterised by large deviation range but was always suffi- cient to insert the endoscopic device and standard otosurgical instruments.

Abstract Objective The objective of this study is to introduce and describe a surgical technique called Osteoplastic Orbitozygomatic-Mastoid-Transattical Craniotomy (Osteoplastic OZ-MT) and to show the possibility of accomplishing osteoplastic craniotomies for other classical lateral transcranial approaches. Technique The Osteoplastic OZ-MT combines many lateral transcranial approaches. The surgical approach involves structures of lateral and basal portions of the skull, from the frontal bone, superolateral-inferolateral-posterolateral walls of the orbit, zygoma, zygomatic process, sphenoid greater and lesser wings, temporal fossa, mandibular fossa, zygomatic process of the temporal bone, petrous pyramid, mastoid, up to the parietal and occipital regions. The temporal muscle is totally preserved and attached to the one-piece-only bone flap.

    640 Indian Journal of Forensic Medicine & Toxicology, January-March 2021, Vol. 15, No. 1 Morphometric study of Macewan’s Triangle in Relation to Depth of the Sigmoid Sinus Plate Senthil Kumar. B Assistant Professor in Anatomy / Head – Central Research Laboratory for Biomedical Research, Vinayaka Mission’s Kirupananda Variyar Medical College and Hospital, Vinayaka Mission’s Research Foundation (Deemed to be University) Salem, TamilNadu, India. Abstract Background: The suprameatal triangle is used for approaching the tympanic cavity and also it is an important landmark for otologic surgeons during mastoidectomy. Aim: To determine the depth of sigmoid sinus plate over the Macewan’s triangle by morphometry of various anatomical landmarks. Materials & Methods: The study was carried out in the Department of Anatomy, Penang International Dental College & VMKV Medical College, Salem on 30 dry human adult skulls. Five landmarks (D1, D2, D3, D4, D5 and D6) were taken on the left and right sides of the skulls and the imaginary lines were constructed and measured by Vernier caliper between the landmarks. Results: The measurement of D2 showed statistically significant differences. The correlations of D1, D3, D4, D5 and D6 on both sides do not show any significant differences. The linear correlation equations were derived using the measurements for predicting D6. Conclusion: The depth of sigmoid sinus plate (D6) can be assessed using D1, D2, D3, D4, D5 on lateral view of head & neck X-rays which can be used by Otologist during mastoidectomy to avoid severe bleeding complications from sigmois sinus. Keywords - Henle’s spine, Suprameatal triangle, Mastoidectomy, Sigmoid sinus, Introduction the matoid antrum of the mastoid process.

    Jemds.com Original Article ANATOMIC STUDY OF LOCALIZATION OF FORAMEN OVALE, CAROTID CANAL, JUGULAR FORAMEN USING HENLE’S SPINE AS SURFACE LANDMARK IN SOUTH INDIAN ADULT SKULLS Yogitha Ravindranath1, Jyotsna Bailur2, Vijay Kishan3, Rema Devi4 1Associate Professor, Department of Anatomy, St. John’s Medical College, Bangalore. 2Post Graduate, Department of Anatomy, St. John’s Medical College, Bangalore. 3Post Graduate, Department of Anatomy, St. John’s Medical College, Bangalore. 4Professor, Department of Anatomy, St. John’s Medical College, Bangalore. ABSTRACT BACKGROUND Henle’s Spine (HS) is a small bony prominence, anterior to the supramastoid pit, at the postero-superior margin of the external acoustic meatus. Localization of cranial structures using this anatomical landmark is of immense surgical importance to identify and avoid surgical morbidities. AIMS Considering the limited number of research articles describing its anatomy in South Indian skulls, present study was conducted to estimate the location and the difference between the right and left sides of the skull base foramen by using HS as surface landmark, which can act as a guide to various approaches of the skull base surgeries. SETTING AND DESIGN Cross-sectional observational study. MATERIALS AND METHODS Twenty nine (58 sides) adult South Indian skulls with prominent HS were studied. Following distances on both right and left sides of the skulls were measured from tip of HS to anterior margin and posterior margin of foramen ovale (HS–AMFO, HS-PMFO); posterolateral and medial jugular foramen (HS-PLJF, HS-PMJF); lateral and medial margin of carotid canal (HS-LMCC, HS-MMCC) using digital calliper of 0.01 mm accuracy.
