Hybrid antero-lateral transcondylar approach to the clivus: a laboratory investigation and case illustration.

Acta Neurochir (Wien) 2020 06 25;162(6):1259-1268. Epub 2020 Apr 25.

Department of Neurosurgery, Hôpital Lariboisière, Assistance Publique-Hôpitaux de Paris, Université de Paris, 2 rue Ambroise Pare, 75010, Paris, France.

Background: Surgical treatment of lesions involving the ventral craniovertebral junction (CVJ) and the lower clivus, traditionally involved complex lateral or transoral approaches to the skull base. However, mid or upper clivus involvement requires more extensive lateral approaches. Recently, the endoscopic endonasal approach (EEA) has become the standard for upper CVJ lesions and medial clival, and a valuable alternative for those tumors extending in its upper third as well as laterally.

Skull Base Osteomyelitis Complicated by Petrous Internal Carotid Artery Blowout.

Ear Nose Throat J 2020 Mar 5:145561320907164. Epub 2020 Mar 5.

Division of Otolaryngology, Brigham and Women's Hospital, Harvard Medical School, Boston, MA, USA.

Skull base osteomyelitis (SBO) is an invasive infection of the external auditory canal, with involvement of the skull base, typically in the elderly diabetic population. Diagnosis may be challenging, as it requires a combination of clinical, laboratory, and radiographical findings. The mainstay of treatment is long-term antibiotic therapy, but surgical debridement of the temporal bone may be necessary in refractory cases. Read More

[Apical petrositis, osteomyelitis of the base of the skull bones and of the first cervical vertebra in a 5 year-old children following chicken pox].

Vestn Otorinolaringol 2016 ;81(1):61-63

Pirogov Russian National Research Medical University, Moscow, Russia, 117997.

This publication was designed to describe a rare case of development of apicalpetrositis in a child presenting with acute otitis mediafollowing chicken pox experienced in the preceding period. We carried out the study with the use of computed tomography (CT) that demonstrated destruction of the temporal bone, bones of the base of the skull and of the first cervical vertebra. The treatment strategy chosen for the management of this condition that included antibiotic therapy and expectant observation proved justified and can be recommended as an algorithm of choice taking into consideration the difficulty of surgical approach to the apex of the petrous pyramid.

Gruber, Gradenigo, Dorello, and Vail: key personalities in the historical evolution and modern-day understanding of Dorello's canal.

J Neurosurg 2016 Jan 26;124(1):224-33. Epub 2015 Jun 26.

Departments of 1 Neurological Surgery and.

A century ago an ambitious young anatomist in Rome, Primo Dorello, who sought to understand the cause of abducent nerve palsy that often occurred in patients with severe middle ear infections, conducted intricate studies on the intracranial course of the nerve. In his findings, he identified that the abducent nerve passes through a narrow sinus near the apex of the petrous bone, which formed an osteofibrous canal. Dorello suggested that in this enclosed region the abducent nerve may be particularly vulnerable to compression due to the vascular edema accompanying the infection. Read More

Indian J Nucl Med 2013 Apr;28(2):65-9

Department of Nuclear Medicine, Postgraduate Institute of Medical Education and Research, Chandigarh, India.

Background: Skull base osteomyelitis (SBO) refers to infection that has spread beyond the external auditory canal to the base of the skull in advanced stages of otitis externa. Clinically, it may be difficult to differentiate SBO from severe otitis externa without bony involvement. This study was performed to determine the role of three phase bone scintigraphy (TPBS) and single photon emission tomography/computed tomography (SPECT/CT) in detecting SBO. Read More

Repair of cerebrospinal fluid leak via petrous bone using multilayer technique with hydroxyapatite paste.

World Neurosurg 2010 Dec;74(6):650-3

Department of Neurosurgery, The University of Tokyo, Tokyo, Japan.

Objective: Repairing bone defects after drilling in skull base surgery is difficult in deeper locations, the posterior wall of the internal auditory canal, and the petrous apex. These defects traditionally have been repaired by soft tissue, such as fascia, muscle, or adipose tissue, coupled with lumbar drainage for several days postoperatively.

Methods: To repair cerebrospinal fluid (CSF) leakage through air cells in the petrous bone, we applied a multilayer technique using hydroxyapatite cement (HAC) in three patients with postoperative CSF leakage. Read More

Isolated sphenoid sinus disease: differential diagnosis and management.

Curr Opin Otolaryngol Head Neck Surg 2011 Feb;19(1):16-20

Department of Otolaryngology, Singapore General Hospital, Singapore.

Purpose Of Review: To review the current literature on isolated disease of sphenoid sinus, and to describe the various approaches to the sphenoid sinus.

Recent Findings: Due to its posterior location and subtle presenting symptoms, sphenoid lesions, in the past, have often been missed and were reported as rare occurrences. However, with the availability of current diagnostic modalities such as endoscopy and imaging techniques such as computed tomography (CT) and magnetic resonance imaging (MRI), diseases of the sphenoid sinus are now more frequently diagnosed.
