These convergences create the so- called “line of fusion.” Its release and elevation are neces- sary to obtain a proper lifting. At its lower position this line of fusion proceeds to the so-called “orbital ligament” situated on the outer upper part of the brow, attached to the superficial temporal fascia at the level of the zygo- matico-frontal suture. Release of this line of fusion is per- formed usually from lateral to medial, thus avoiding a loss of proper plane of elevation because the periosteum and the posterior temporal fascia inserts on the temporal crest and the release at this level will continue to proceed under the periosteum and posterior fascia of the frontalis muscle. However, it can often be released from superior to inferior as I have done without any difficulties in hug- ging the temporal crest. This elevates the deeper levels of periosteum on both sides in a maneuver similar to the elevation of the periosteum over the zygomatic arch, which is done from medial to lateral and from lateral to medial in a maneuver designed to prevent any injury to the temporal branch. The “C-line” release is performed as follows: Release of the orbital ligaments is performed at the lateral border of the brow. Over the temple and laterally the superficial Figure 1.

  • 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.

  • Preservation of the Nerves to the Frontalis Muscle During Pterional Craniotomy
    LABORATORY INVESTIGATION J Neurosurg 122:1274–1282, 2015 Preservation of the nerves to the frontalis muscle during pterional craniotomy Tomas Poblete, MD, Xiaochun Jiang, MD, Noritaka Komune, MD, PhD, Ken Matsushima, MD, and Albert L. Rhoton Jr., MD Department of Neurological Surgery, University of Florida, Gainesville, Florida OBJECT There continues to be confusion over how best to preserve the branches of the facial nerve to the frontalis muscle when elevating a frontotemporal (pterional) scalp flap.The object of this study was to examine the full course of the branches of the facial nerve that must be preserved to maintain innervation of the frontalis muscle during elevation of a frontotemporal scalp flap. METHODS Dissection was performed to follow the temporal branches of facial nerves along their course in 5 adult, cadaveric heads (n = 10 extracranial facial nerves). RESULTS Preserving the nerves to the frontalis muscle requires an understanding of the course of the nerves in 3 areas. The first area is on the outer surface of the temporalis muscle lateral to the superior temporal line (STL) where the interfascial or subfascial approaches are applied, the second is in the area medial to the STL where subpericranial dis- section is needed, and the third is along the STL. Preserving the nerves crossing the STL requires an understanding of the complex fascial relationships at this line. It is important to preserve the nerves crossing the lateral and medial parts of the exposure, and the continuity of the nerves as they pass across the STL. Prior descriptions have focused largely on the area superficial to the temporalis muscle lateral to the STL.
