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 . -
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.)

Simple Ways to Dissect Ciliary Ganglion for Orbital Anatomical Education

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). -

NICULESCU, A. MOTOC, S. BOLINTINEANU, IZABELLA SARGAN, M. C. NICULESCU Department of Anatomy and Embryology “Victor Babeş” University of Medicine and Pharmacy, Timişoara Abstract The study conducted on 60 human cadavers preserved in formalin, in the Anatomy Laboratory of the “Victor Babes” University of Medicine and Pharmacy Timisoara, during 2000–2006, observed the internal and external jugular veins from the point of view of their origin, course and affluents. The morphological variability of the jugular veins (external jugular that receives as affluents the facial and lingual veins and drains into the internal jugular, draining the latter’s territory – 3.33%; internal jugular that receives the lingual, upper thyroid and facial veins, independent – 13.33%, via the linguofacial trunk – 50%, and via thyrolinguofacial trunk – 33.33%) made possible the correlation of these anomalies with disorders in the ontogenetic development of the veins of the neck. Knowing the variants of origin, course and drainage area of jugular veins is important not only for the anatomist but also for the surgeon operating at this level.

This study described changes in the following structures: retromandibular vein and its divisions, including the relationship with the facial nerve, facial vein, common facial vein and jugular veins. Material and Methods: The variations of the veins were analyzed in three heads, five hemi-heads (right side) and two hemi-heads (left side) of unknown age and sex. Results: The changes only on the right side of the face were: union between the superficial temporal and maxillary veins at a lower level; absence of the common facial vein and facial vein draining into the external jugular vein. While on the left, only, it was noted: posterior division of retromandibular, after unite with the common facial vein, led to the internal jugular vein; union between the posterior auricular and common facial veins to form the external jugular and union between posterior auricular and common facial veins to terminate into internal jugular. -
