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 objective of present study was to radiologically localize greater 1Department of Anatomy, Azeezia Institute of Medical Sciences, palatine foramen with multiple anatomical landmarks. All Computer Tomography scans India of individuals who have undergone paranasal sinus evaluation were obtained from the 2Department of Radiology, Azeezia Institute of Medical Sciences, Department of Radiology, Azeezia Institute of Medical Sciences, from April 2015 to April India 2016. Distance of greater palatine foramen from various known anatomical landmarks was measured across the CT slices. Forty-four CT scans were studied, mean age was 32(±2.3) Correspondence: Viveka S, Assistant professor, Department years. All scans were from individuals of south Indian origin. GPF was located at 38.38mm of Anatomy, Azeezia Institute of Medical Sciences, Kollam, India, from incisive fossa, 17.6mm from posterior nasal spine, 18.38mm from intermaxillary Email [email protected] suture, 5.03mm from second molar and 5.28mm from third molar. Distances of GPF from incisive foramen and intermaxillary suture differed significantly on right and left sides. In Received: May 25, 2016 | Published: December 29, 2016 25(56.8%) cases GPF was located closer to third molar. In seven cases, it was closer to second molar and in 12 cases, GPF was located at the junction of second and third molar. Posterior location of GPF, posterior to third molar is not noted. -
Hard Palate, Intermaxillary Sulcus, Greater Palatine Foramen, Lesser Palatine Foramen
Basic Sciences of Medicine 2020, 9(3): 44-45 DOI: 10.5923/j.medicine.20200903.02 Twin Foramina in Posterior Third of an Adult Hard Palate and Their Significance Rajani Singh Department of Anatomy, UP University of Medical Sciences, Saifai Etawah, India Abstract Hard palate is formed by union of maxillary process of palatine bone and horizontal plate of palatine bone during development of foetus in 12th week. Three types of foramina, greater palatine allowing greater palatine nerves and vessels, lesser palatine and incisive foramina allowing passage of lesser palatine and nasopalatine nerves respectively are normally present in hard palate. The purpose of study is to report two novel foramina in hard palate and to bring out associated clinical significance. The author observed two new foramina one on either side of intermaxillary sulcus at the junction of anterior 2/3rd and posterior 1/3rd of hard palate during scanning of base of skulls for any abnormality in the Department of Anatomy of my native institute. The diameters of the right sided foramen was 6 mm while that of on left sided was 5 mm. The distance of foramen from midline on the right side was 3 mm while that of on left side was 2 mm. The distance of foramen on the right side from the centre of inferior border of hard palate was 13 mm while that of left side was 10 mm. The hard palate separates nasal cavity and oral cavity and essential for speech, feeding and respiration. The anomalous foramina observed may create problems during speech, feeding and respiration. -

Atlas of the Facial Nerve and Related Structures
Rhoton Yoshioka Atlas of the Facial Nerve Unique Atlas Opens Window and Related Structures Into Facial Nerve Anatomy… Atlas of the Facial Nerve and Related Structures and Related Nerve Facial of the Atlas “His meticulous methods of anatomical dissection and microsurgical techniques helped transform the primitive specialty of neurosurgery into the magnificent surgical discipline that it is today.”— Nobutaka Yoshioka American Association of Neurological Surgeons. Albert L. Rhoton, Jr. Nobutaka Yoshioka, MD, PhD and Albert L. Rhoton, Jr., MD have created an anatomical atlas of astounding precision. An unparalleled teaching tool, this atlas opens a unique window into the anatomical intricacies of complex facial nerves and related structures. An internationally renowned author, educator, brain anatomist, and neurosurgeon, Dr. Rhoton is regarded by colleagues as one of the fathers of modern microscopic neurosurgery. Dr. Yoshioka, an esteemed craniofacial reconstructive surgeon in Japan, mastered this precise dissection technique while undertaking a fellowship at Dr. Rhoton’s microanatomy lab, writing in the preface that within such precision images lies potential for surgical innovation. Special Features • Exquisite color photographs, prepared from carefully dissected latex injected cadavers, reveal anatomy layer by layer with remarkable detail and clarity • An added highlight, 3-D versions of these extraordinary images, are available online in the Thieme MediaCenter • Major sections include intracranial region and skull, upper facial and midfacial region, and lower facial and posterolateral neck region Organized by region, each layered dissection elucidates specific nerves and structures with pinpoint accuracy, providing the clinician with in-depth anatomical insights. Precise clinical explanations accompany each photograph. In tandem, the images and text provide an excellent foundation for understanding the nerves and structures impacted by neurosurgical-related pathologies as well as other conditions and injuries. -
