Free-Flap Reconstruction of Skull Base and Orbital Defects.

Semin Plast Surg 2019 Feb 8;33(1):72-77. Epub 2019 Mar 8.

Department of Facial Plastic and Reconstructive Surgery, Otolaryngology and Facial Plastic Surgery Associates, Fort Worth, Texas.

Orbital and anterior skull base defects present a significant challenge for reconstruction due to the complexity of the anatomy and the need for separation of intracranial and extracranial contents in this area. While endoscopic techniques have revolutionized the treatment of many anterior skull base defects, microvascular free tissue transfer is a viable option for large volume defects not suitable for traditional open approaches or for cases where endoscopic techniques have failed. The various free tissue transfer techniques for anterior skull base and orbit, as well as the advantages and disadvantages, are reviewed. Read More

Various modifications of a vascularized nasoseptal flap for repair of extensive skull base dural defects.

J Neurosurg 2019 Feb 8:1-9. Epub 2019 Feb 8.

OBJECTIVEEndonasal surgery of the skull base requires watertight reconstruction of the skull base that can seal the dural defect to prevent postoperative CSF rhinorrhea and consequent intracranial complications. Although the incidence of CSF leakage has decreased significantly since the introduction in 2006 of the vascularized nasoseptal flap (the Hadad-Bassagasteguy flap), reconstruction of extensive skull base dural defects remains challenging. The authors describe a new, modified vascularized nasoseptal flap for reconstruction of extensive skull base dural defects. 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

Moulded Osteomyofascial Pedicled Split (MOPS) Craniotomy Flap in Reconstruction of Anterior Cranial Fossa Defects: Pilot Study of a Novel Technique.

Asian J Neurosurg 2018 Oct-Dec;13(4):1011-1017

Department of Neurosurgery, Government Medical College, Kottayam, Kerala, India.

Introduction: Anterior cranial fossa (ACF) defects still remains a reconstructive challenge to neurosurgeons due to the difficult location, inaccessibility, and unfavorable vascular anatomy. Usual reconstructive methods reported complications such as recurrent cerebrospinal fluid leak due to bone resorption and tissue breakdown. This is mainly due to the avascularity of the bone graft and inability to provide bony structural support for the skull base. Read More
