Preservation of venous drainage in middle fossa during combined transpetrosal approach for petroclival meningioma.

World Neurosurg 2018 Dec 6. Epub 2018 Dec 6.

Department of Neurosurgery, Tokyo Medical University, #6-7-1 Nishishinjuku, Shinjuku-ku, Tokyo 160-0023, Japan.

The combined transpetrosal approach enables wide exposure around the petroclival region by lifting of the middle fossa dura and cutting of the tentorium. However, interruption of the venous drainage on the middle skull base during the transpetrosal approach has been reported to lead to temporal lobe damage.(1,2) This video (Video 1) demonstrates a microsurgical technique for the preservation of various venous drainage in the middle fossa, including the sphenobasal and sphenopetrosal veins, during the combined transpetrosal approach for treatment of a petroclival meningioma.

Braincase and endocranial anatomy of two thalattosuchian crocodylomorphs and their relevance in understanding their adaptations to the marine environment.

PeerJ 2018 26;6:e5686. Epub 2018 Nov 26.

CONICET. División Paleontología Vertebrados, Museo de La Plata, Facultad de Ciencias Naturales y Museo, Universidad Nacional de La Plata, La Plata, Buenos Aires, Argentina.

Thalattosuchians are a group of Mesozoic crocodylomorphs known from aquatic deposits of the Early Jurassic-Early Cretaceous that comprises two main lineages of almost exclusively marine forms, Teleosauridae and Metriorhynchoidea. Teleosaurids were found in shallow marine, brackish and freshwater deposits, and have been characterized as semiaquatic near-shore forms, whereas metriorhynchids are a lineage of fully pelagic forms, supported by a large set of morphological characters of the skull and postcranial anatomy. Recent contributions on Thalattosuchia have been focused on the study of the endocranial anatomy. Read More

Role of transcranial sphenoidotomy in skull base surgery: classification of surgical techniques based on the surgical anatomy of the sphenoid sinus.

J Neurosurg 2018 Nov 1:1-10. Epub 2018 Nov 1.

2Department of Neurosurgery, Fukushima Medical University, Fukushima; and.

OBJECTIVEAlthough sphenoidotomy is more commonly performed via the transnasal approach than via the transcranial approach, transcranial sphenoidotomy (TCS) remains indispensable for en bloc resection of locally advanced sinonasal malignant tumors (SNMTs) extending to the skull base. TCS also enables transsphenoidal transposition of the temporoparietal galeal flap (TPGF) to compensate for the lack of vascularized reconstructive tissue after endoscopic transnasal skull base surgery. The objective of this study was to review the authors' surgical experience using TCS with an emphasis on the surgical anatomy of the sphenoid sinus and on the purpose of TCS. Read More

Tendinous Inscriptions of the Rectus Abdominis: A Comprehensive Review.

Cureus 2018 Aug 4;10(8):e3100. Epub 2018 Aug 4.

Neurosurgery, Seattle Science Foundation, Seattle, USA.

The rectus abdominis muscles are interrupted by tendinous inscriptions, which typically appear as fibrous bands crossing the muscle. The current literature on tendinous inscriptions is scarce; hence, this review will provide a detailed overview of their anatomical description, including their variation, embryology, comparative anatomy, and clinical application. Understanding the anatomy and function of the tendinous inscription assists in providing clinical relevance and in guiding reconstructive surgeons in their surgical planning and design. Read More

Clin Exp Otorhinolaryngol 2019 Feb 18;12(1):12-17. Epub 2018 Oct 18.

Department of Otolaryngology-Head and Neck Surgery, Seoul St. Mary's Hospital, College of Medicine, The Catholic University of Korea, Seoul, Korea.

Endoscopic sinus and skull base surgeries are minimally invasive surgical techniques that reduce postoperative symptoms and complications and enhance patients' quality of life. However, to ensure excellent surgical outcomes after such interventions, intimate familiarity with important landmarks and high-level endoscope manipulation skills are essential. Cadaver training is one possible option, but cadavers are expensive, scarce, and nonreusable and cadaver work requires specialized equipment and staff. Read More
