Anatomy Tip Trigeminal Nerve (CN 5) In an effort to aid Health Information Management Coding Professionals for ICD-10, the following anatomy tip is provided with an educational intent. TIP: The Trigeminal Nerve is the largest of the cranial nerves, providing sensory information to the head and face, with motor nerves supporting the muscles of mastication. The Trigeminal nerve has three major branches: 1. The Ophthalmic Nerve (V1) 2. The Maxillary Nerve (V2) 3. The Mandibular Nerve (V2) The Ophthalmic nerve carries only sensory fibers. Branches include nasociliary nerve and its branches; posterior ethmoidal nerve, long ciliary nerve, infratrochlear nerve, anterior ethmoidal nerve, the lacrimal nerve, the frontal nerve and its branches; supratroclear nerve, supraorbital nerve. The Maxillary nerve carries sensory fibers. Branches include middle meningeal nerve, Infraorbital nerve, zygomatic nerve, nasopalantine nerves, superior alveolar nerves, palatine nerves, pharyngeal nerve, inferior palpebral nerve, superior labial nerve. The Mandibular nerve has motor and sensory functions. Branches include nervous spinosus, medial pterygoid nerve (to tensor tympani and tensor veli palatini), masseteric nerve, deep temporal nerves, buccal nerve, lateral pterygoid nerve, auriculotemporal nerve, lingual nerve, inferior alveolar nerve, motor branch to mylohyoid and digastric muscles.

Palatal Injection Does Not Block the Superior Alveolar Nerve Trunks: Correcting an Error Regarding the Innervation of the Maxillary Teeth
Open Access Review Article DOI: 10.7759/cureus.2120 Palatal Injection does not Block the Superior Alveolar Nerve Trunks: Correcting an Error Regarding the Innervation of the Maxillary Teeth Joe Iwanaga 1 , R. Shane Tubbs 2 1. Seattle Science Foundation 2. Neurosurgery, Seattle Science Foundation Corresponding author: Joe Iwanaga, [email protected] Abstract The superior alveolar nerves course lateral to the maxillary sinus and the greater palatine nerve travels through the hard palate. This difficult three-dimensional anatomy has led some dentists and oral surgeons to a critical misunderstanding in developing the anterior and middle superior alveolar (AMSA) nerve block and the palatal approach anterior superior alveolar (P-ASA) nerve block. In this review, the anatomy of the posterior, middle and anterior superior alveolar nerves, greater palatine nerve, and nasopalatine nerve are revisited in order to clarify the anatomy of these blocks so that the perpetuated anatomical misunderstanding is rectified. We conclude that the AMSA and P-ASA nerve blockades, as currently described, are not based on accurate anatomy. Categories: Anesthesiology, Medical Education, Other Keywords: anatomy, innervation, local anesthesia, maxillary nerve, nerve block, tooth Introduction And Background Anesthetic blockade of the posterior superior alveolar (PSA) branch of the maxillary nerve has played an important role in the endodontic treatment of irreversible acute pulpitis of the upper molar teeth except for the mesiobuccal root of the first molar tooth [1, 2]. This procedure requires precise anatomical knowledge of the pterygopalatine fossa and related structures in order to avoid unnecessary complications and to make the blockade most effective. The infraorbital nerve gives rise to middle superior alveolar (MSA) and anterior superior alveolar (ASA) branches.

The purpose of this study was to determine the correlation between IANB failure and mandibular skeletal characteristics Methods: In total, 693 cases of lower third molar extraction (n = 575 patients) were examined in this study. The ratio of the condylar and coronoid distances from the mandibular foramen (condyle-coronoid ratio [CC ratio]) was calculated, and the mandibular skeleton was then classified as normal, retrognathic, or prognathic. The correlation between IANB failure and sex, treatment side, and the CC ratio was assessed. Results: The IANB failure rates for normal, retrognathic, and prognathic mandibles were 7.3%, 14.5%, and 9.5%, respectively, and the failure rate was highest among those with a CC ratio < 0.8 (severe retrognathic mandible). The failure rate was significantly higher in the retrognathic group than in normal group (P = 0.019), and there was no statistically significant difference between the other two groups. Conclusions: IANB failure could be attributable, in part, to the skeletal characteristics of the mandible.

Nerves of the Orbit Optic Nerve the Optic Nerve Enters the Orbit from the Middle Cranial Fossa by Passing Through the Optic Canal
human anatomy 2016 lecture fourteen Dr meethak ali ahmed neurosurgeon Nerves of the Orbit Optic Nerve The optic nerve enters the orbit from the middle cranial fossa by passing through the optic canal . It is accompanied by the ophthalmic artery, which lies on its lower lateral side. The nerve is surrounded by sheath of pia mater, arachnoid mater, and dura mater. It runs forward and laterally within the cone of the recti muscles and pierces the sclera at a point medial to the posterior pole of the eyeball. Here, the meninges fuse with the sclera so that the subarachnoid space with its contained cerebrospinal fluid extends forward from the middle cranial fossa, around the optic nerve, and through the optic canal, as far as the eyeball. A rise in pressure of the cerebrospinal fluid within the cranial cavity therefore is transmitted to theback of the eyeball. Lacrimal Nerve The lacrimal nerve arises from the ophthalmic division of the trigeminal nerve. It enters the orbit through the upper part of the superior orbital fissure and passes forward along the upper border of the lateral rectus muscle . It is joined by a branch of the zygomaticotemporal nerve, whi(parasympathetic secretomotor fibers). The lacrimal nerve ends by supplying the skin of the lateral part of the upper lid. Frontal Nerve The frontal nerve arises from the ophthalmic division of the trigeminal nerve. It enters the orbit through the upper part of the superior orbital fissure and passes forward on the upper surface of the levator palpebrae superioris beneath the roof of the orbit .

Regional Anesthesia in Head and Neck Surgery
TITLE: Regional Anesthesia in Head and Neck Surger SOURCE: Grand Rounds Presentation, UTMB, Dept. of Otolaryngology DATE: May 24, 2006 RESIDENT PHYSICIAN: Jacques Peltier, MD FACULTY PHYSICIAN: Francis B. Quinn, MD SERIES EDITORS: Francis B. Quinn, Jr., MD and Matthew W. Ryan, MD "This material was prepared by resident physicians in partial fulfillment of educational requirements established for the Postgraduate Training Program of the UTMB Department of Otolaryngology/Head and Neck Surgery and was not intended for clinical use in its present form. It was prepared for the purpose of stimulating group discussion in a conference setting. No warranties, either express or implied, are made with respect to its accuracy, completeness, or timeliness.

Introduction Local anesthetic techniques were popularized early in the history of surgery with the advent of injectable nerve blocking agents. Until their discovery, patients were either held down or knocked unconscious to perform procedures. In the early days of general anesthesia, local anesthesia was preferred in all cases that it was applicable due to the significant risks associated with general anesthesia. Many procedures performed today under general anesthesia, such as tonsillectomy, rhinoplasty, and even bronchoscopy, were performed under local anesthesia to avoid the perils of general anesthetics. With the introduction of pulse oximetry, safer inhaled anesthetics, and combined intravenous and inhaled general anesthesia techniques, general anesthesia has become much safer, resulting in many surgeons being unfamiliar with regional nerve blocks to perform surgery.

Cranial Nerve Palsy
Cranial Nerve Palsy What is a cranial nerve? Cranial nerves are nerves that lead directly from the brain to parts of our head, face, and trunk. There are 12 pairs of cranial nerves and some are involved in special senses (sight, smell, hearing, taste, feeling) while others control muscles and glands. Which cranial nerves pertain to the eyes? The second cranial nerve is called the optic nerve. It sends visual information from the eye to the brain. The third cranial nerve is called the oculomotor nerve. It is involved with eye movement, eyelid movement, and the function of the pupil and lens inside the eye. The fourth cranial nerve is called the trochlear nerve and the sixth cranial nerve is called the abducens nerve. They each innervate an eye muscle involved in eye movement. The fifth cranial nerve is called the trigeminal nerve. It provides facial touch sensation (including sensation on the eye). What is a cranial nerve palsy? A palsy is a lack of function of a nerve. A cranial nerve palsy may cause a complete or partial weakness or paralysis of the areas served by the affected nerve. In the case of a cranial nerve that has multiple functions (such as the oculomotor nerve), it is possible for a palsy to affect all of the various functions or only some of the functions of that nerve. What are some causes of a cranial nerve palsy? A cranial nerve palsy can occur due to a variety of causes. It can be congenital (present at birth), traumatic, or due to blood vessel disease (hypertension, diabetes, strokes, aneurysms, etc).

Maxillary Nerve-Mediated Postseptoplasty Nasal Allodynia: a Case Report
E CASE REPORT Maxillary Nerve-Mediated Postseptoplasty Nasal Allodynia: A Case Report Shikha Sharma, MD, PhD,* Wilson Ly, MD, PharmD,* and Xiaobing Yu, MD*† Endoscopic nasal septoplasty is a commonly performed otolaryngology procedure, not known to cause persistent postsurgical pain or hypersensitivity. Here, we discuss a unique case of persis- tent nasal pain that developed after a primary endoscopic septoplasty, which then progressed to marked mechanical and thermal allodynia following a revision septoplasty. Pain symptoms were found to be mediated by the maxillary division of the trigeminal nerve and resolved after percuta- neous radiofrequency ablation (RFA) of bilateral maxillary nerves. To the best of our knowledge, this is the first report of maxillary nerve–mediated nasal allodynia after septoplasty. (A&A Practice. 2020;14:e01356.)

Here, we would like to introduce simple ways to find the CG by 1): tracing the sensory and parasympathetic roots to find the CG from the superior direction above the orbit, 2): transecting and retracting the lateral rectus muscle to visualize the CG from the lateral direction of the orbit, and 3): taking out whole orbital structures first and dissecting to observe the CG. The advantages and disadvantages of these methods are discussed from the standpoint of decreased laboratory time and students as beginners at orbital anatomy. Introduction dissection course for the first time and with limited time. In addition, there are few clear pictures in anatomical The ciliary ganglion (CG) is one of the four para- textbooks showing the morphology of the CG. There are sympathetic ganglia in the head and neck region located some scientific articles concerning how to visualize the behind the eyeball between the optic nerve and the lateral CG, but they are mostly based on the clinical approaches rectus muscle in the apex of the orbit (Siessere et al., rather than based on the anatomical procedure for medical 2008).

The Mandibular Nerve - Vc Or VIII by Prof
The Mandibular Nerve - Vc or VIII by Prof. Dr. Imran Qureshi The Mandibular nerve is the third and largest division of the trigeminal nerve. It is a mixed nerve. Its sensory root emerges from the posterior region of the semilunar ganglion and is joined by the motor root of the trigeminal nerve. These two nerve bundles leave the cranial cavity through the foramen ovale and unite immediately to form the trunk of the mixed mandibular nerve that passes into the infratemporal fossa. Here, it runs anterior to the middle meningeal artery and is sandwiched between the superior head of the lateral pterygoid and tensor veli palatini muscles. After a short course during which a meningeal branch to the dura mater, and the nerve to part of the medial pterygoid muscle (and the tensor tympani and tensor veli palatini muscles) are given off, the mandibular trunk divides into a smaller anterior and a larger posterior division. The anterior division receives most of the fibres from the motor root and distributes them to the other muscles of mastication i.e. the lateral pterygoid, medial pterygoid, temporalis and masseter muscles. The nerve to masseter and two deep temporal nerves (anterior and posterior) pass laterally above the medial pterygoid. The nerve to the masseter continues outward through the mandibular notch, while the deep temporal nerves turn upward deep to temporalis for its supply. The sensory fibres that it receives are distributed as the buccal nerve. The 1 | P a g e buccal nerve passes between the medial and lateral pterygoids and passes downward and forward to emerge from under cover of the masseter with the buccal artery.
