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

Acta Neurochir (Wien) 2020 Jun 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.

[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

Institute of Neuroradiology, University Hospital of Zurich, Frauenklinikstr. 10, 8091, Zurich, Switzerland.

Cranio-maxillofacial injuries affect a significant proportion of trauma patients either in isolation or concurring with other serious injuries. Contrary to maxillofacial injuries that result from a direct impact, central skull base and lateral skull base (petrous bone) fractures usually are caused by a lateral or sagittal directed force to the skull and therefore are indirect fractures. The traditional strong role of conventional images in patients with isolated trauma to the viscerocranium is decreasing. Read More

Malignant otitis externa--a high index of suspicion is still needed for diagnosis.

Ir Med J 2002 Jan;95(1):14-6

Department of Otolaryngology/Head and Neck Surgery, RCSI Education and Research Centre, Beaumont Hospital, Dublin.

Malignant otitis externa is a destructive inflammatory process of the petrous temporal bone which if untreated leads to osteomyelitis of the skull base and can be fatal. It is more common in immunocompromised and elderly insulin-dependant diabetic patients and is caused by infection with Pseudomonas species. Despite a range of laboratory and radiological tests it still remains difficult to diagnose, particularly in the early stages when it can be treated medically. Read More

Department of Radiology, University of Rochester Medical Center, NY, USA.

A 37-year-old woman with a skull base infection sustained massive oropharyngeal bleeding after incisional nasopharyngeal biopsy and drainage of a prevertebral abscess. A pseudoaneurysm originating at the petrous portion of the internal carotid artery was initially misinterpreted on MR images as typical postoperative change within a resolving abscess cavity. Follow-up MR imaging and conventional angiography ultimately disclosed the pseudoaneurysm. Read More

Venous channels of the petrous apex: their presence and clinical importance.

Otolaryngol Head Neck Surg 1997 Feb;116(2):168-74

Department of Otolaryngology-Head and Neck Surgery, University of California, Davis, USA.

A methyl methacrylate casting technique was used to make detailed casts of the intracerebral venous system of four human cadaver specimens. Seven of the eight petrous apices studied were diploeic (n = 5), or pneumatic (n = 2) and had venules coursing in the anterior petrous apex. These venules form conduits connecting the cavernous to the inferior petrosal sinus or the jugular bulb and have not been previously described. Read More

Malignant otitis externa in HIV and AIDS.

J Laryngol Otol 1996 Aug;110(8):770-5

Department of Otolarynology, St Mary's Hospital, London, UK.

Malignant otitis externa is a necrotising infection of the external ear canal which may spread to include the mastoid and petrous parts of the temporal bone, leading to skull base osteomyelitis. It is almost exclusively caused by infection with Pseudomonas aeruginosa, and usually occurs in elderly non-insulin-dependent diabetic patients. However isolated cases have been reported in a small number of non-diabetic patients, particularly in children who are immunocompromised due to malignancy, malnutrition and severe anaemia. Read More

Osteomyelitis of the skull base: the role of high resolution CT in diagnosis.

Clin Radiol 1994 Jun;49(6):408-11

Department of Neuroradiology, Atkinson Morley's Hospital, London.

Osteomyelitis of the skull base (involving the temporal, occipital or sphenoid bones) is an uncommon condition occurring in elderly diabetic patients which was almost always fatal in the pre-antibiotic era. Despite the advent of effective antibiotics against the usual causative organism, Pseudomonas aeruginosa, the mortality remains high and is related to delay in diagnosis and inappropriate treatment. We report three cases of osteomyelitis of the skull base, in order to illustrate the difficulties encountered in diagnosis and management. Read More

Aneurysmal cyst of the petrosal bone.

Arch Dis Child 1993 Aug;69(2):241-2

Department of Paediatrics, Städtisches Klinikum Fulda, Teaching Hospital, University of Marburg, Federal Republic of Germany.

An aneurysmal cyst of the petrosal bone presenting as hearing loss and recurrent bacterial meningitis is reported. None of the clinical or radiographic signs described previously were present. Because other diagnostic methods are not reliable, it is recommended that coronal thin section computed tomography be performed in every case of suspected malformation of the skull base and in the diagnosis of recurrent bacterial meningitis.

Ann Otolaryngol Chir Cervicofac 1990 ;107(5):341-4

Servic d'ORL, Groupe Hospitalier Pitié-Salpêtrière, Paris.

Pseudomonas aeruginosa is often isolated in infections of the ear cleft. In some circumstances, this organism can cause serious petrous or peri-petrous lesions. Two pictures are seen: Malignant external otitis with severe headaches, signs of external otitis, and usually pseudomonas aeruginosa is isolated. Read More

Atypical osteomyelitis of the skull base.

Laryngoscope 1989 Jul;99(7 Pt 1):671-6

Department of Otolaryngology, University of Miami, Fla.

Most cases of osteomyelitis of the skull base occur as a result of inadequately treated localized malignant otitis externa. We present four patients with osteomyelitis of the skull base who did not present initially as malignant otitis externa. Increased morbidity may occur when these atypical cases are not promptly recognized and treated. Read More

Subtemporal-preauricular infratemporal fossa approach to large lateral and posterior cranial base neoplasms.

J Neurosurg 1987 Oct;67(4):488-99

Department of Neurological Surgery, University of Pittsburgh School of Medicine, Pennsylvania.

A subtemporal-preauricular infratemporal fossa approach to remove 22 large neoplasms involving the lateral and posterior cranial base is detailed. The areas from which a neoplasm could be removed by this approach included the sphenoid and clival bone; the medial half of the petrous temporal bone; the infratemporal fossa; the nasopharynx; the retro- and parapharyngeal area; the ethmoid, sphenoid, and maxillary sinuses; and the intradural clivus-foramen magnum area. The pathology of the neoplasms included benign tumors such as meningioma, malignant cartilaginous neoplasms such as chordoma, and other malignant lesions such as nasopharyngeal carcinoma. Read More

Obliteration of the middle ear and mastoid cleft in subtotal petrosectomy: indications, technique, and results.

Ann Otol Rhinol Laryngol 1986 Jan-Feb;95(1 Pt 1):5-11

Lateral surgical approaches to the base of the skull through the temporal bone often result in a large cavity with exposed dura and vascular structures and no possibility of reconstruction of the middle ear conductive hearing mechanism. Subtotal petrosectomy with tympanomastoid obliteration provides a relatively safe and secure closure of the surgical defect in the temporal bone and eliminates the problems associated with an open mastoid cavity. Eradication of all accessible air cell tracts and mucosa in the petrous pyramid, obliteration of the eustachian tubal orifice, closure of the external auditory canal, and fat obliteration of the middle ear and mastoid clefts are essential in the procedure.

Tuberculous petrous apicitis.

Arch Otolaryngol 1985 Jun;111(6):406-8

Tuberculous osteomyelitis of the temporal bone is a rare and dangerous entity that should be included in the differential diagnoses of infectious processes of the base of skull. A 21-year-old man presented with petrous apicitis, extradural and retromandibular abscesses, and paresis of the facial nerve. Immediate middle fossa craniotomy and drainage of the extradural abscess, in combination with a mastoidectomy, incision and drainage of the facial abscess, and antimicrobial therapy for gram-positive cocci, failed to check the destructive nature of the infection.

Treatment of invasive external otitis with cefsulodin.

Rev Infect Dis 1984 Sep-Oct;6 Suppl 3:S698-704

Thirteen patients with invasive infections of the external ear were treated with cefsulodin sodium. Eleven were elderly diabetic patients with malignant external otitis, and two were nondiabetic adults with cellulitis or chondritis of the external ear. Four of 11 patients with malignant external otitis had extensive disease, with progression of infection to the petrous apex, medial base of the skull, or parapharyngeal soft tissue. Read More
