Methods: Three men and three women aged 21e79 years (average, 55 years) were treated for defects of the nasal ala and upper lip that resulted from cancer (n Z 4) and trauma (n Z 2). Unaffected contralateral subunits dictated the flap design. The upper lip subunit was excised and replaced with a nasolabial flap. The flap, depending on the contralateral reference, determined accurate alar base position. A forehead flap resurfaced or replaced the nasal ala. Autologous cartilage was used in every case to fortify the forehead flap reconstruction. Results: Patients were followed for 25.6 months (range, 1e4 years).

  • Temporo-Mandibular Joint (Tmj) Dysfunction
    Office: (310) 423-1220 BeverlyHillsENT.com Fax: (310) 423-1230 TEMPORO-MANDIBULAR JOINT (TMJ) DYSFUNCTION You may not have heard of it, but you use it hundreds of times every day. It is the Temporo- Mandibular Joint (TMJ), the joint where the mandible (the lower jaw) joins the temporal bone of the skull, immediately in front of the ear on each side of your head. You move the joint every time you chew or swallow. You can locate this joint by putting your finger on the triangular structure in front of your ear. Then move your finger just slightly forward and press firmly while you open your jaw all the way and shut it. The motion you feel is the TMJ. You can also feel the joint motion in your ear canal. These maneuvers can cause considerable discomfort to a patient who is having TMJ trouble, and physicians use these maneuvers with patients for diagnosis. TMJ Dysfunction can cause the following symptoms: Ear pain Sore jaw muscles Temple/cheek pain Jaw popping/clicking Locking of the jaw Difficulty in opening the mouth fully Frequent head/neck aches The pain may be sharp and searing, occurring each time you swallow, yawn, talk, or chew, or it may be dull and constant. It hurts over the joint, immediately in front of the ear, but pain can also radiate elsewhere. It often causes spasms in the adjacent muscles that are attached to the bones of the skull, face, and jaws. Then, pain can be felt at the side of the head (the temple), the cheek, the lower jaw, and the teeth.

  • Implications to Occipital Headache
    The Journal of Neuroscience, March 6, 2019 • 39(10):1867–1880 • 1867 Neurobiology of Disease Non-Trigeminal Nociceptive Innervation of the Posterior Dura: Implications to Occipital Headache X Rodrigo Noseda, Agustin Melo-Carrillo, Rony-Reuven Nir, Andrew M. Strassman, and XRami Burstein Department of Anesthesia, Critical Care and Pain Medicine, Beth Israel Deaconess Medical Center and Harvard Medical School, Boston, Massachusetts 02115 Current understanding of the origin of occipital headache falls short of distinguishing between cause and effect. Most preclinical studies involving trigeminovascular neurons sample neurons that are responsive to stimulation of dural areas in the anterior 2/3 of the cranium and the periorbital skin. Hypothesizing that occipital headache may involve activation of meningeal nociceptors that innervate the posterior 1⁄3 of the dura, we sought to map the origin and course of meningeal nociceptors that innervate the posterior dura overlying the cerebellum. Using AAV-GFP tracing and single-unit recording techniques in male rats, we found that neurons in C2–C3 DRGs innervate the dura of the posterior fossa; that nearly half originate in DRG neurons containing CGRP and TRPV1; that nerve bundles traverse suboccipital muscles before entering the cranium through bony canals and large foramens; that central neurons receiving nociceptive information from the posterior dura are located in C2–C4 spinal cord and that their cutaneous and muscle receptive fields are found around the ears, occipital skin and neck muscles; and that administration of inflammatory mediators to their dural receptive field, sensitize their responses to stimulation of the posterior dura, peri-occipital skin and neck muscles. These findings lend rationale for the common practice of attempting to alleviate migraine headaches by targeting the greater and lesser occipital nerves with anesthetics.

  • Core Strength Exercises
    CORE STRENGTH EXERCISES • The main muscles involved with Core Strength include muscles of the abdomen, hip flexors and low back postural muscles. • It is important to maintain proper strength of these muscles to prevent and rehabilitate from low back / pelvic dysfunction and pain. • All of these exercises should be comfortable and not produce pain or discomfort. Bracing: The Key to preventing low back injuries Abdominal Bracing – Lying down • Lie down, face up with your knees bent and feet on floor. • Contract your stomach muscles so that you imagine pushing your low back to the floor or that you are pulling your belly button to your spine. Abdominal Bracing - Standing • Stand up straight and place one hand on the small of the back and one hand on your abdomen. • Bend Forward at the waist and feel the lower back muscles contract (extensors). • Come back up to neutral to relax the low back muscles. • You will feel the low back muscles contract when you contract your abdominal and gluteal muscles. Bracing technique and curling • Lay on the ground on your back. • One leg is bent and the other leg remains flat on the floor. Your hands can be on your chest or at your side. • Fix your eyes on a spot on the ceiling directly above you. • Tighten your stomach muscles. • Holding the stomach contraction, lift your shoulder blades and head off the floor while looking at that spot on the ceiling. Hold for 3-10 seconds and repeat three times. • Switch leg positions and repeat the technique. Beginner to Intermediate position • Position yourself on your hands and knees with your pelvis and thighs at 90 degrees and upper back and arms at 90 degrees.

    FAMSI © 2007: Ximena Chávez Balderas Human Sacrifice and Mortuary Treatments in the Great Temple of Tenochtitlán Research Year: 2005 Culture: Mexica Chronology: Postclassic Location: México City, México Site: Tenochtitlán Table of Contents Introduction The bone collection in study Human sacrifice and mortuary treatments Methodology Osteobiography Tafonomic analysis Sacrifice by heart extraction Decapitation: Trophy skulls, Tzompantli skulls and elaboration of skull masks Skull masks Population analysis based upon DNA extraction Preliminary results Final considerations List of Figures Sources Cited Introduction The present report describes the study undertaken with the osteologic collection obtained from the Great Temple excavations in Tenochtitlán; this collection was assembled in the interval from 1978 to 2005. The financial support granted to us by FAMSI enabled the creation of four lines of research: 1) packing and preventive conservation; 2) osteobiography; 3) mortuary treatments; and 4) population genetics. Immediately, a detailed exposition of the work and its results up to the present moment will be given. Submitted 11/16/2006 by: Ximena Chávez Balderas [email protected] Figure 1. General view of the archaeological zone of the Great Temple in México City. 2 The bone collection in study For the present study the human remains found in 19 offerings in the Great Temple of Tenochtitlán were analyzed. This place symbolizes the axis mundi for the Mexicas. The deposits were temporarily situated in the period comprehended between 1440 and 1502 A.D., which corresponds mostly to stage IVb (1469-1481 A.D.). The total number of bodies studied was 1071. From these, seventy-four were recovered in the context of offerings and correspond to skull masks, decapitated skulls, tzompantli skulls, isolated remains and a primary context.

This phenomenon, influenced by complex religious beliefs, included several practices such as decapitation, cranial deformation, and the use of human cranial bones for skull mask manufacturing. Archaeological evidence suggests that all of these practices required specialized knowledge of skull base and upper cervical anatomy. The authors con- ducted a systematic search for information on skull base anatomical and surgical knowledge among Mesoamerican civilizations. A detailed exposition of these results is presented, along with some interesting information extracted from historical documents and pictorial codices to provide a better understanding of skull base surgical practices among these cultures. Paleoforensic evidence from the Great Temple of Tenochtitlan indicates that Aztec priests used a specialized decapitation technique, based on a deep anatomical knowledge.
