Forward Head Posture Fix
The dermatomal distribution of the neck innervation is in cervical nerves 2 through 4. Regional block anesthesia is targeted at these nerves in a paravertebral location. The cervical plexus is comprised of the anterior divisions of cervical nerves 1 through 4. The plexus sits anterior to the median scalene and levator scapulae, and behind the sternocleidomastoid muscles. The cervical plexus divides into superficial and deep branches. It is the deep branches that innervate the deep structures of the neck including the muscles via an internal and an external series of nerves. The internal series consists of the following nerves communicating branches, mus
After placing the patient in a neutral supine position, and appropriately prepping the skin for aseptic technique, a 4- or 5-cm 22-gauge needle with a short bevel is used to instill local anesthetic. An example of local anesthetic that could be used is a half-and-half mix of 1 lidocaine and 0.5 bupivacaine. A total of about 3 or 4cc of local anesthetic should be used at each level. To find the proper position for needle placement at all levels, an imaginary line can be drawn between the tip of the mastoid process and Chassaignac's tubercle of C6, which is palpable at the level of, and posterior to, the cricoid cartilage. The C2 injection is performed about 1 to 1.5 cm below the mastoid process on this line, just posterior to the sternocleidomastoid. Moving about 1.5 cm caudad from the C2 site along the same line can place injections at C3 and C4. A horizontal line from the ramus of the mandible posterior can be a guide to the level of the C4 injection site as well. A slight caudal...
The interscalene nerve block is a modification of the technique described by Winnie in 1970. In the classical technique of Winnie, the interscalene nerve block is performed at the posterior scalene gap. This puncture site is thus at the level of the cricoid. The puncture is made in the medial, dorsal and caudal direction. In the modified technique, by contrast, the puncture point is located at the height of the superior thyroid notch at the posterior edge of the sternocleidomastoid muscle. The puncture is directed caudad, slightly to the lateral and aims at the puncture site of the vertical-infraclavicular blockade (see Chapter 2.2).

Tion, and the gamma fibers are precisely motor fibers to the muscle spindle. Activation of these fibers produce contraction of the spindle and, therefore, as the structure becomes slightly shorter, it is more sensitive to the overall stretch of the whole muscle. This is a way to adjust the sensitivity to stretch or, expressed in other words, to introduce bias to the system. Since the gamma efferent neural pathways recognize their origin in the higher centers, many times psychological stress increases their outflow leading to painful muscle spasms because their spindles have been sensitized. Neck muscles are frequently the targets of these spasms. This is to be distinguished from the local and also painful muscular contracture (cramps) typically taken place in the legs. The latter may be caused by a variety of maladjustments, such as low glucose, fluid loss, electrolyte imbalance, overexertion, or fatigue. The exact physiologic mechanisms underlying cramps are not fully understood.
On physical examination, the patient had a non-tender mass located just anterior to the sternocleidomastoid muscle in the anterior triangle of the neck. The mass was mobile in a back-forwards direction, but could not be moved in the cranial-caudal direction. No signs of cranial nerve deficits were detected. An echo-duplex showed a highly vascularised structure adherent with the carotid artery located in the bifurcation.
The accessory nucleus is found in the cervical spinal cord. The axons of the spinal accessory-nerve arise from the accessory nucleus, pass through the foramen magnum to enter the cranial cavity, and join the fibers of the vagus to exit the cranial cavity through the jugular foramen. As a result, intramedullary lesions do not affect fibers of the spinal accessory nerve. The spinal accessory nerve supplies the sternocleidomastoid and trapezius muscles.

Expiratory phase becomes prolonged and the patient develops tachypnea, tachycardia, and mild systolic hypertension. Accessory muscles of respiration (sternocleidomastoid and intercostals) may be used to improve breathing. If the asthma attack is severe, the patient will develop a pulsus paradoxus (an inspiratory drop in systolic blood pressure of more than 10 mm Hg). Patients with epiglottitis present with fever, drooling, and dysphagia lung examination will be normal. Children with croup or laryngo-tracheobronchitis present with labored breathing and stridor, and use accessory muscles to assist breathing.
Regardless of the design of the program, specific guidelines should be followed. Within each session, individuals should perform large muscle groups (prime movers) before smaller muscle groups (secondary movers) to avoid fatigue of the larger muscles. However, smaller, stabilizing muscles (rotator cuff, hip adductor abductor, neck muscles, etc.) should not be neglected. If left untrained, these smaller, stabilizing muscles are at risk for injury. The Valsalva maneuver, holding the breath during exertion, should never be performed. To avoid a reduction in venous return to the heart and a significant increase in blood pressure, individuals should exhale on exertion. As always, medical clearance should be sought before beginning an exercise program if an individual has a condition that maybe made worse by exercise.
Head Positioning in Radiography of the Maxilla Using the Bisecting Technique. In radiography of the maxilla, the head should be positioned so that the occlusal surfaces of the maxillary teeth are in a horizontal plane (see figure 4-2). This is done by adjusting the headrest so that the median plane (sagittal plane) is vertical and a line from the ala of the nose to the tragus of the ear is horizontal. Figure 4-2. Head position for making maxillary periapical radiographs. b. Head Positioning in Radiography of the Mandible Using the Bisecting Technique. In periapical radiography of the mandible, the head should be positioned so that the occlusal surfaces of the mandibular teeth will be horizontal when the mouth is opened to the position in which the radiographs are to be made (see figure 4-3). This is done by adjusting the headrest so the median plane is vertical and a line from the corner of the mouth to the tragus of the ear is horizontal. Figure 4-2. Head position for making...
Botox was first approved by the FDA in 1989 as a treatment for spastic eye and neck muscles. In 2002, it was approved for cosmetic use to relax the small muscles that cause frowning. Studies are under way for non-cosmetic uses of Botox, including treating migraine headaches, inhibiting excess sweating, relaxing spastic urinary bladder (a common cause of incontinence), and even treating obesity by relaxing the muscles of the stomach wall to slow gastric emptying.
Surgical removal of nodule on lip and radical neck dissection (removal of submandibular gland adhered to affected submandibular nodes , sternocleidomastoid muscle, omohyoid, accessory nerve, and internal jugular vein). Important regions in the anatomy of this disease include the submandibular triangle (between the two anterior bellies of the digastric containing the submandibular lymph nodes) muscular triangle (omohyoid, sternocleidomastoid, median line, containing some deep cervical lymph nodes) carotid triangle (sternocleidomastoid, omohyoid, posterior belly of digastric, containing internal jugular vein and deep cervical nodes) and posterior cervical triangle (trapezius, sternocleidomastoid, omohyoid, containing deep cervical nodes near accessory nerve).
Caused by acute spasm of neck muscles due to inflammatory changes because of undue straining the muscles that are usually involved are the trapezius, supraspinatus, rhomboid, splenius capitis, levator scapula, scalenus medius, splenius cervicis, and, in severe cases, transverse ligament, allowing subluxation of one vertebra on another. Torticollis may also be congenital due to unilateral fibrosis of the sternocleidomastoid muscle.
The neck can be divided into two compartments an anterior or visceral part containing the hyoid bone, pharynx, esophagus, larynx, and associated cartilages, and a posterior or vertebral compartment consisting mostly of muscles associated with cervical vertebrae and the ventral rami of the cervical plexus and brachial plexus. Both compartments are partially covered by two superficial muscles, the trapezius and the sternocleidomastoid, which serve to divide each side of the neck into anterior and posterior triangles (Figure III-6-1). Sternocleidomastoid muscle Sternocleidomastoid muscle In the posterior triangle cutaneous branches of the cervical plexus (great auricular, lesser occipital, transverse cervical, and supraclavicular nerves) emerge at the midpoint of the sternocleidomastoid muscle. These nerves supply the skin of the neck and posterior scalp.
Lesions of the trochlear nerve produce a diplopia when attempting to depress the adducted eye. The diplopia is most apparent when the patient looks down and away from the lesioned side. Patients complain of difficulty in reading or difficulty in going down stairs. A loss of intorsion may also be important diagnostically in CN IV lesions. Here, the patient tilts his or her head away from the side of the lesioned nerve to counteract the extorsion by the unopposed inferior oblique and inferior rectus muscles. In children, the head tilt might be mistaken for torticollis caused by abnormal contractions of the sternocleidomastoid muscle.
Catheters are placed in the internal jugular vein in the same way as in the subclavian, using the Seldinger technique with the ideal point of penetration being the apex of the triangle that is formed by the clavicle and sternal and clavicular heads of the sternocleidomastoid. The patient must be in the Trendelenburg position. The right internal jugular vein is preferred because it extrudes almost directly into the right innominate vein and the superior vena cava. Much care must be taken with elderly people in whom, because of their age, coiling of the carotid artery may have displaced the internal jugular vein. The jugular catheters usually have curved edges for a better and practical result.
This examination is usually done for the purpose of diagnosing malformations of long bones caused by disease, a retardation of bone growth, or a stoppage of the normal bone growth process. The patient will usually exhibit various symptoms such as curvature of the extremities (bowlegs, knock-knee, etc.) or a shortening of one of the extremities. When shortening does occur, differentiation can be established as to whether the shortening is functional or anatomical. This is accomplished by measurements of both related extremities to determine actual figures. An anatomically short extremity will show a shorter measurement of the bones than the other. Conversely, a functionally short extremity, usually due to occupation or bad posture, will have the same bone measurement as the other comparative extremity. The shortening in the latter case is due to the carrying angle of the body. A long bone series, then, is a comparative study in which both related extremities are examined. Suggested...
It may be impossible to differentiate a rheg-matogenous from an exudative retinal detachment clinically or ultrasonographically. The old rule that shifting subretinal fluid indicates exudative detachment often does not hold in uveitis as inflammation can increase the protein content of the subretinal fluid and result in changes in the shape and extent of detachment with head position. However, stiff, contracted retina or extensive epiretinal membrane formation is likely to occur only in rhegmatogenous detachment.
When preparing for a mandibular exposure using the bisecting technique, the head position should be such that the occlusal surfaces of the mandibular teeth will be_when the mouth is opened. 17. Describe the head positioning and direction of the x-rays for the mandibular anterior occlusal technique.
Treatment Surgical removal of nodule on lip and radical neck dissection (removal of submandibular gland adhered to affected submandibular nodes , sternocleidomastoid muscle, omohyoid, accessory nerve, and internal jugular vein). Discussion Important regions in the anatomy of squamous cell carcinoma of the lip include the submandibular triangle (between the base of the mandible and the anterior and posterior bellies of the digastric) the muscular triangle (omohyoid, sternocleidomastoid, median line, containing some deep cervical lymph nodes) the carotid triangle (sternocleidomastoid, omohyoid, posterior belly of digastric, containing internal jugular vein and deep cervical nodes) and the posterior cervical triangle (trapezius, sternocleidomastoid, omohyoid, containing deep cervical nodes near accessory nerve).
Drooling requires constant attention from a patient or caregiver, may lead to breakdown of the skin, and is socially disastrous. It is common in cerebral palsy, stroke, and neurodegenerative diseases such as motorneurone disease (ALS) and Parkinsonism (PD). Patients with PD do not produce excessive saliva,15 but do experience reduced swallowing,16 The common forward head posture probably contributes to drooling. Systemic drugs such as anticholinergics may help but are often poorly tolerated, and a few patients undergo surgical denervation or parotid gland irradiation to reduce saliva production.
As I spoke, the Buddha would begin to stir. He would almost imperceptibly begin to rock his body to and fro, and a low-pitched moan would emanate from his throat. The students rarely noticed this movement until it was too late. The Buddha would suddenly raise himself upright and begin to stamp his feet madly, then rock from one foot to another in a two-legged standing position. Every hair bristled from the muscles of his aging body it was quite a show, and the students were riveted. He would then surge about his rocky outcrop, picking up piles of his feces and flinging them with impressive accuracy at the students (I was always careful to take a step back as this unfolded) from his bipedal standing posture. If they remembered nothing else from that semester, my students always knew years later who had been slimed by that lonely, bored chimpanzee.
The anterior triangle is bounded by the anterior border of the sternocleidomastoid muscle, the anterior midline, and the body of the mandible (Figure 10-6-1). Subdivisions of the anterior triangle contain the strap muscles, the submandibular gland, the common carotid, internal carotid and external carotid arteries, and parts of cranial nerves X and XII. The strap muscles consist of a series of five pairs of muscles which have attachments to bony or cartilaginous structures adjacent to the midline beginning at the sternum and extending to the underside of the mandible. Strap muscles act on the mandible, hyoid bone, and thyroid cartilage. There are two major muscular branches of the cervical plexus, the ansa cervicalis and the phrenic nerve. The cervical plexus is formed by the ventral rami of spinal nerves from CI through C4 and is situated behind the sternocleidomastoid muscle and in front of the scalenus medius and levator scapulae muscles.
May be caused by a tumor pressing on CN IX X, antfSl Patients present with hoarseness, dysphagia (CN X), loss of sensation over the oropharynx and posterior one third of the tongue (CN IX), trapezius and sternocleidomastoid weakness (CN XI). The nearby CN XII may be involved producing tongue deviation to the lesioned side.
