In this article, we shall look at the anatomy of the mandibular nerve — its anatomical course, branches, sensory, motor and autonomic functions. The motor root runs along the floor or the trigeminal cave , beneath the ganglion, joining the sensory root before leaving the cranium through the foramen ovale.

Oral surgical and dental procedures are often performed in an outpatient setting. Regional anesthesia is the most common method of anesthetizing the patient before office-based procedures. Several highly efficacious and practical techniques can be used to achieve anesthesia of the dentition and surrounding the hard and soft tissues of the maxilla and mandible. The type of procedure to be performed as well as the location of the procedure determine the technique of anesthesia to be used. Orofacial anesthetic techniques can be classified into three main categories: local infiltration, a field block, and nerve block.

The Mandibular Division of the Trigeminal Nerve (CNV3)

Regional anesthesia is commonly used for postoperative pain management to decrease postoperative pain and opioid consumption following head and neck surgery. Myriad techniques can be used for both acute and chronic pain management either diagnostic or therapeutic procedures. Because of the vicinity of cranial and cervical nerves to many vital structures in a compact area, the efficacy and safety of cephalic nerve blocks are based on precise and detailed knowledge of the anatomical relationships of the selected nerve, its deep and superficial courses, and the final sensory territories. Sensory innervation of the face and neck is supplied by the trigeminal nerve fifth cranial or V and the C2—C4 cervical nerve roots that constitute the superficial cervical plexus Figure 1A. This section outlines clinically applicable regional nerve blocks of the face that for perioperative and chronic pain management. For each nerve block, practical anatomy, indications, technique, and type of complications are specifically described.

The fifth cranial nerve is known as the trigeminal nerve and has 3 branches which are the ophthalmic, maxillary, and mandibular. The third branch is called the mandibular nerve V3. It is the largest of the 3 branches and carries both afferent and efferent fibers. The first 2 branches of the trigeminal nerve carry only afferent fibers. From the brain stem, the mandibular branch arises from 3 nuclei mesencephalic, principal sensory and spinal and gives rise to the sensory root and one motor nucleus gives rise to the motor root of the nerve. The motor root runs along the floor or the trigeminal cave and joins the larger sensory root before leaving the cranium base as the mandibular branch of the trigeminal nerve through the foramen ovale in the sphenoid bone and enters the infratemporal fossa. Near the skull base, the main trunk immediately gives off the sensory meningeal branch and motor muscular branches to the medial pterygoid, tensor tympani, and tensor veli palatini.

Nerve Blocks of the Face

Orofacial myofascial pain is prevalent and most often results from entrapment of branches of the trigeminal nerves. It is challenging to inject branches of the trigeminal nerve, a large portion of which are shielded by the facial bones. Bony landmarks of the cranium serve as important guides for palpation-guided injections and can be delineated using ultrasound. Ultrasound also provides real-time images of the adjacent muscles and accompanying arteries and can be used to guide the needle to the target region. Most importantly, ultrasound guidance significantly reduces the risk of collateral injury to vital neurovascular structures.

The inferior alveolar nerve block is the most common injection technique used in dentistry and many modifications of the conventional nerve block have been recently described in the literature. Selecting the best technique by the dentist or surgeon depends on many factors including the success rate and complications related to the selected technique. Dentists should be aware of the available current modifications of the inferior alveolar nerve block techniques in order to effectively choose between these modifications. Some operators may encounter difficulty in identifying the anatomical landmarks which are useful in applying the inferior alveolar nerve block and rely instead on assumptions as to where the needle should be positioned. In this basic review, the anatomical details of the inferior alveolar nerve will be given together with a description of its both conventional and modified blocking techniques; in addition, an overview of the complications which may result from the application of this important technique will be mentioned. The inferior alveolar nerve block, a common procedure in dentistry, involves the insertion of a needle near the mandibular foramen in order to deposit a solution of local anesthetic near to the nerve before it enters the foramen, a region where the inferior alveolar vein and artery are also present.

Oral & Maxillofacial Regional Anesthesia

The authors investigated the efficacy of bilateral suprazygomatic maxillary nerve block SMB for postoperative pain relief in infants undergoing cleft palate repair. In this prospective, double-blind, single-site, randomized, and parallel-arm controlled trial, 60 children were assigned to undergo bilateral SMB with general anesthesia with either 0. The primary endpoint was total postoperative morphine consumption at 48 h. Pain scores and respiratory- and SMB-related complications were noted. Continuous morphine infusion was less frequent in the Ropi group compared with that in the Saline group 1 patient [3.

Anatomy is a basic knowledge that every clinician must have; however, its full management is not always achieved and gaps remain in daily practice. The aim of this chapter is to emphasize the most relevant aspects of head and neck anatomy, specifically related to osteology and neurology for the application of regional anesthesia techniques. This chapter presents a clear and concise text, useful for both undergraduate and graduate students and for the dentist and maxillofacial surgeon. The most relevant aspects of the bone and sensory anatomy relevant for the realization of regional anesthetic techniques in the oral and maxillofacial area are reviewed, including complementary figures and tables.

 Тебе больше нечем заняться? - Сьюзан метнула на него недовольный взгляд. - Хочешь от меня избавиться? - надулся Хейл. - Если честно - да, - Не надо так, Сью, Ты меня оскорбляешь.

Anatomy Applied to Block Anesthesia for Maxillofacial Surgery

Ничего себе маленькая шишка, - подумал Беккер, вспомнив слова лейтенанта. Посмотрел на пальцы старика - никакого золотого кольца. Тогда он дотронулся до его руки. - Сэр? - Беккер легонько потормошил спящего.  - Простите, сэр… Человек не шевельнулся.

Рванувшись вниз за своей жертвой, он продолжал держаться вплотную к внешней стене, что позволило бы ему стрелять под наибольшим углом. Но всякий раз, когда перед ним открывался очередной виток спирали, Беккер оставался вне поля зрения и создавалось впечатление, что тот постоянно находится впереди на сто восемьдесят градусов. Беккер держался центра башни, срезая углы и одним прыжком преодолевая сразу несколько ступенек, Халохот неуклонно двигался за. Еще несколько секунд - и все решит один-единственный выстрел. Даже если Беккер успеет спуститься вниз, ему все равно некуда бежать: Халохот выстрелит ему в спину, когда он будет пересекать Апельсиновый сад.
