The motor infra-orbital nerves are comparatively of larger size, and consist of superficial and deep branches which pass forward over the masseter muscle to be distributed to the muscles beneath the lower margin of the orbit and about the mouth. The superficia l branches supply the superficial muscles of the face and form sensory connections with the nasal and infra-trochlear nerves along the nose.

  • Computed Tomography of the Buccomasseteric Region: 1
    605 Computed Tomography of the Buccomasseteric Region: 1. Anatomy Ira F. Braun 1 The differential diagnosis to consider in a patient presenting with a buccomasseteric James C. Hoffman, Jr. 1 region mass is rather lengthy. Precise preoperative localization of the mass and a determination of its extent and, it is hoped, histology will provide a most useful guide to the head and neck surgeon operating in this anatomically complex region. Part 1 of this article describes the computed tomographic anatomy of this region, while part 2 discusses pathologic changes. The clinical value of computed tomography as an imaging method for this region is emphasized. The differential diagnosis to consider in a patient with a mass in the buccomas­ seteric region, which may either be developmental, inflammatory, or neoplastic, comprises a rather lengthy list. The anatomic complexity of this region, defined arbitrarily by the soft tissue and bony structures including and surrounding the masseter muscle, excluding the parotid gland, makes the accurate anatomic diagnosis of masses in this region imperative if severe functional and cosmetic defects or even death are to be avoided during treatment. An initial crucial clinical pathoanatomic distinction is to classify the mass as extra- or intraparotid. Batsakis [1] recommends that every mass localized to the cheek region be considered a parotid tumor until proven otherwise. Precise clinical localization, however, is often exceedingly difficult. Obviously, further diagnosis and subsequent therapy is greatly facilitated once this differentiation is made. Computed tomography (CT), with its superior spatial and contrast resolution, has been shown to be an effective imaging method for the evaluation of disorders of the head and neck.

  • 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.

  • Anatomy of the Face] 2018-2019
    By Dr. Hassna B. Jawad [ANATOMY OF THE FACE] 2018-2019 Objective : At the end of this lecture you should be able to : 1. Identify the extent of the face. 2. Enlist the layers of the face and recognize their importance 3. Recognize the groups of the muscles of facial expression its origin ,insertion and function 4. Test the muscle of facial expression clinically 5. Discuss some clinical notes regarding the face Extends from lower border of mandible to the hair line (forehead is common for face and scalp) and laterally to the ear auricle Layers Of the Face 1.SKIN The face has elastic and vascular skin. The skin of the face has large number of sweat and sebaceous glands. The sebaceous glands keep the face greasy by their secretion and sweat glands help modulate the body temperature *Applied Anatomy :Face is also the common site for acne as a result of presence of large number of sebaceous glands in this region. 2. SUPERFICIAL FASIA It includes muscles of facial expression, vessels and nerves and varying amount of fat. The fat is absent in the eyelids but is well grown in cheeks creating buccal pad of fat, which gives rounded contour to cheeks. 3. DEEP FASCIA The deep fascia is absent in the region of face with the exception of over the parotid gland and masseter muscle that are covered by parotidomasseteric fascia. The absence of deep fascia in the face is important for the facial expression. The majority of them originate from bones of the skull and are added into the skin.

  • The Five Diaphragms in Osteopathic Manipulative Medicine: Myofascial Relationships, Part 1
    Open Access Review Article DOI: 10.7759/cureus.7794 The Five Diaphragms in Osteopathic Manipulative Medicine: Myofascial Relationships, Part 1 Bruno Bordoni 1 1. Physical Medicine and Rehabilitation, Foundation Don Carlo Gnocchi, Milan, ITA Corresponding author: Bruno Bordoni, [email protected] Abstract Working on the diaphragm muscle and the connected diaphragms is part of the respiratory-circulatory osteopathic model. The breath allows the free movement of body fluids and according to the concept of this model, the patient's health is preserved thanks to the cleaning of the tissues by means of the movement of the fluids (blood, lymph). The respiratory muscle has several systemic connections and multiple functions. The founder of osteopathic medicine emphasized the importance of the thoracic diaphragm and body health. The five diaphragms (tentorium cerebelli, tongue, thoracic outlet, thoracic diaphragm and pelvic floor) represent an important tool for the osteopath to evaluate and find a treatment strategy with the ultimate goal of patient well-being. The two articles highlight the most up-to-date scientific information on the myofascial continuum for the first time. Knowledge of myofascial connections is the basis for understanding the importance of the five diaphragms in osteopathic medicine. In this first part, the article reviews the systemic myofascial posterolateral relationships of the respiratory diaphragm; in the second I will deal with the myofascial anterolateral myofascial connections. Categories: Medical Education, Anatomy, Osteopathic Medicine Keywords: diaphragm, osteopathic, fascia, myofascial, fascintegrity, physiotherapy Introduction And Background Osteopathic manual medicine (OMM) was founded by Dr AT Still in the late nineteenth century in America [1]. OMM provides five models for the clinical approach to the patient, which act as an anatomy physiological framework and, at the same time, can be a starting point for the best healing strategy [1].
