The trigeminal nerve. Part II: the ophthalmic division.

The ophthalmic, or first division (V1) of the trigeminal nerve, is the smallest of the three divisions and is purely sensory or afferent in function. It supplies sensory branches to the ciliary body, the cornea, and the iris; to the lacrimal gland and conjunctiva; to portions of the mucous membrane of the nasal cavity, sphenoidal sinus, and frontal sinus; to the skin of the eyebrow, eyelids, forehead, and nose; and to the tentorium cerebelli, dura mater, and the posterior area of the falx cerebri. At first glance, one might not expect one interested in the diagnosis and treatment of orofacial pain and temporomandibular joint disorders to have a need to be concerned with the ophthalmic division. Although much of this division's influence is dedicated to structures within the orbit, nose, and cranium, still, the ophthalmic division may be afflicted with a lesion or structural disorder which can cause all sorts of orofacial pain. Ignorance of this or any portion of the trigeminal nerve will lead to diagnostic and therapeutic failures. In this, the second of four (4) articles concerning the trigeminal nerve, the first division of this vast cranial nerve will be described in detail.

The trigeminal nerve. Part III: The maxillary division.

The maxillary nerve gives sensory innervation to all structures in and around the maxillary bone and the midfacial region including the skin of the midfacial regions, the lower eyelid, side of nose, and upper lip; the mucous membrane of the nasopharynx, maxillary sinus, soft palate, palatine tonsil, roof of the mouth, the maxillary gingivae, and maxillary teeth. This vast and complex division of the trigeminal nerve is intimately associated with many sources of orofacial pain, often mimicking maxillary sinus and/or temporomandibular joint involvement. For those who choose to treat patients suffering with orofacial pain and temporomandibular disorders, knowledge of this nerve must be second nature. Just providing the difficult services of a general dental practice should be stimulus enough to understand this trigeminal division, but if one hopes to correctly diagnose and treat orofacial pain disorders, dedication to understanding this nerve cannot be overstated. In this, the third of a four part series of articles concerning the trigeminal nerve, the second or maxillary division will be described and discussed in detail.

The trigeminal nerve. Part IV: the mandibular division.

The mandibular or third division of the trigeminal nerve is the largest of the three divisions. It is considered a mixed nerve. That is, like the ophthalmic and maxillary divisions, the mandibular conveys afferent fibers. But unlike the former two divisions, the mandibular also contains motor or efferent fibers to the muscles of mastication, the mylohyoid and anterior digastric muscles, and the tensor veli palatini and tensor tympani muscles. So intimately associated with dentistry, the mandibular nerve has also been termed the dental nerve by anatomists in the past. This extensive and complicated division of the trigeminal nerve can cause confusion to both patient and doctor. Pain is often referred within its branches and even into other trigeminal divisions, chiefly the maxillary. This fourth and last article about the trigeminal nerve will present in detail the mandibular division.

Migraine and tension-type headache reduction through pericranial muscular suppression: a preliminary report.

Migraine and tension-type headaches have always plagued mankind. In spite of all the research dollars spent trying to determine the etiologies of these headaches, the neurology community still has not established a known cause of migraine and tension type headaches. This paper describes a study that was conducted for the U.S. Food and Drug Administration in which the efficacy of the Nociceptive Trigeminal Inhibition Tension Suppression System was evaluated and proved safe and efficacious in the reduction of medically diagnosed migraine and tension-type headache.

Alternative to the inferior alveolar nerve block anesthesia when placing mandibular dental implants posterior to the mental foramen.

Local anesthesia block of the inferior alveolar nerve is routinely taught throughout dental education. This commonly used technique eliminates all somatosensory perception of the mandible, mandibular teeth, floor of the mouth, ipsilateral tongue, and all but the lateral (buccal) gingivae. Generally, the dentist or surgeon desires these structures to be anesthetized. However, in the placement of mandibular implants, it may be useful for the patient to be able to sense when the inferior alveolar nerve is in danger of being damaged, possibly producing permanent paresthesia. In this article, the technique of mandibular infiltration prior to mandibular implant placement in the mandible is discussed.

Nociceptive trigeminal inhibition--tension suppression system: a method of preventing migraine and tension headaches.

Dentists and physicians see countless patients suffering from various types of headaches. Various modes of therapy are used in an attempt to treat these patients. As a result of this study, it appears that a common factor to migraine and tension-type headaches may be chronic clenching. If this is the case, then dentists may treat headache patients more effectively than previously suspected through the use of a dental appliance.

The trigeminal nerve. Part I: An over-view.

The trigeminal nerve is the largest and most complex of twelve cranial nerves. Its vast size and influence are greatly appreciated when one attempts to diagnose and treat patients suffering from orofacial pain and temporomandibular joint disorders. Without a thorough knowledge of the trigeminal nerve, the efficacy of diagnostic and therapeutic procedures will be very disappointing. This is the first of a four-part series of articles about the trigeminal nerve, a basic over-view of both the gross and neuroanatomical structures is presented.

The effects of glucosamine and chondroitin sulfate on osteoarthritis of the TMJ: a preliminary report of 50 patients.

The signs and symptoms of osteoarthritis are common complaints seen in patients suffering with chronic temporomandibular disorders (TMD), specifically, internal derangements with a diagnosis of osteoarthritis. With or without the complaints of pain and swelling, joint noises are bothersome and annoying to both the patient and at times, to those seated close to the patient during mealtime. In fact, many patients are driven to seek care by family members because of his or her TMJ noises. For years in veterinarian medicine, glucosamine and chondroitin sulfates have been used to treat symptoms of osteoarthritis. Recently, the use of these two supplements has been recommended for human beings as well. Reports of decreased joint noises, pain and swelling after the administration of therapeutic doses of these supplements have sparked an interest in their possible use in the treatment of osteoarthritis.

Pterygoid hamulus bursitis: one cause of craniofacial pain.

Craniofacial pain disorders are frustrating to the doctor and the patient. Diagnosis is often difficult because the anatomy of the head and neck region is complex, grossly and neurologically. Frequently, several pain syndromes exhibit similar symptoms. One such disorder is bursitis of the pterygoid hamulus. This type of bursitis may produce symptoms of soft palatal, ear, and throat pain, maxillary pain, and difficulty and pain on swallowing. This disorder is often misdiagnosed as otitis media. Treatment may be conservative or surgical. This article discusses the anatomy, symptoms, diagnosis, and treatment of bursitis of the hamular process.

The "pre-anterior belly" of the temporalis muscle: a preliminary study of a newly described muscle.

Gross anatomical structures of the human body have been known and taught to students for centuries. However, at times, anomalies or even previously undescribed structures are discovered and subsequently reported. This preliminary report discusses the discovery of either a previously undescribed belly of the temporalis muscle, a previously undescribed muscle of mastication, or simply an anomaly of the temporalis. The somatosensory innervation of this structure was identified and will be presented. Preliminary measurements of this structure will also be provided. Finally, clinical implications of these findings, which may aid in the diagnosis and treatment of temporal and facial pain, will be discussed.

Bursitis of the hamular process. Part I: Anatomical and histological evidence.

Pain originating from the throat may emanate from many different structures. The stylohyoid and stylomandibular ligaments are known as structures, that when injured, produce most of the throat pain which also may be referred to the face, ears, and temporomandibular joints. Another structure which may produce similar pain complaints, the synovial bursa of the tensor veli palatini muscle, has been isolated and described in this study. The histology and pertinent anatomy of the general area and this bursa specifically will be described.
