1/10. Gradenigo's syndrome.

    Gradenigo's syndrome, which is characterised by the triad of suppurative otitis media, pain in the distribution of the trigeminal nerve, and abducens nerve palsy may give rise to potentially fatal complications. knowledge of the aetiology and appropriate investigations can lead to early diagnosis. A case is reported which illustrates this.

2/10. Conservative management of Gradenigo syndrome in a child.

    Gradenigo syndrome consists of the association of otitis media, facial pain in regions innervated by the first and second division of trigeminal nerve and abducens nerve paralysis. It is caused by osteitis of the petrous apex (PA) and is a very rare complication of otitis media. Its treatment usually consists in mastoidectomy and antibiotics. We report a case of a 6-year-old child, which was managed medically with a positive outcome.

3/10. Sigmoid sinus thrombosis with contralateral abducens palsy: first report of a case.

    Intracranial complications of acute and chronic otitis media can be difficult to recognize because the signs and symptoms are often subtle. This article describes a case of one such complication--sigmoid sinus thrombosis--that was manifested by a contralateral abducens palsy. The author believes that this is the first reported case of such an occurrence. This article also reviews the differential diagnosis of increased intracranial pressure and discusses the recognition and management of lateral sinus thrombosis.

4/10. abducens nerve palsy as the sole presenting symptom of petrous apicitis.

    Petrous apicitis as a potentially fatal complication of suppurative otitis media presents in a variety of forms. Gradenigo's triad of abducens paralysis, deep facial pain due to trigeminal involvement and acute suppurative otitis media rarely occurs. The conflicting symptoms reported in the literature usually result in the delayed recognition of the condition with potentially disastrous consequences. The VIth nerve palsy is considered to be the least reliable sign as it is least often present. We present a case in which it was the sole presenting symptom.

5/10. streptococcus acidominimus infection in a child causing Gradenigo syndrome.

    Gradenigo syndrome is a rare presentation of acute petrositis. The clinical triad of Gradenigo syndrome consists of acute suppurative otitis media, severe unilateral headache and abducens nerve palsy. We report the first case of Gradenigo syndrome caused by streptococcus acidominimus, a Gram-positive coccus of the streptococcus viridans group, which rarely causes deep-seated infection in humans. CONCLUSION: Gradenigo syndrome may complicate acute otitis media and should be suspected in case of unilateral headache and abducens nerve palsy. Conservative medical treatment without surgery may be considered in some patients.

6/10. Gradenigo's syndrome--a rare complication of otitis media.

    Petrous apicitis is a rare intracranial complication of otitis media. A 4-year-old female child was presented with persistent ear discharge, retro-orbital pain and lateral rectus palsy (triad of Gradenigo's syndrome). A right temporal burr-hole was placed and tapping was done under antibiotic coverage. Turbid cerebrospinal fluid could be drained. Follow-up could not be done as the patient refused treatment and was discharged against medical advice.

7/10. Gradenigo syndrome: a case-report.

    We report a case of sixth nerve palsy as a rare complication of acute otitis media (apical petrositis). The clinical triad of acute otitis media, pain in the distribution of the fifth cranial nerve and sixth nerve palsy is known as Gradenigo syndrome.

8/10. Acute onset of abducens nerve palsy in a child with prior history of otitis media: a misleading sign of Gradenigo syndrome.

    Gradenigo syndrome in children during otitis media is a very rare complication since the use of antibiotics: nevertheless, it must be taken into account in case of otitis media, abducens nerve paralysis and facial pain in regions innervated by the first and second division of trigeminal nerve. We report the case of a 4-year-old boy whose neurological signs and clinical history prompted us to entertain a diagnosis of Gradenigo syndrome, which was not confirmed by CT and MRI findings, revealing otomastoiditis and sinus thrombosis.

9/10. Sixth and tenth nerve palsy secondary to pseudomonas infection of the skull base.

    PURPOSE: To describe skull base osteomyelitis, an uncommon complication of chronic otitis media in the post-antibiotic era, as a cause for diplopia. DESIGN: Case report. methods: The records of a patient with skull base osteomyelitis were reviewed. RESULTS: A patient presented with a sixth nerve palsy and tenth nerve palsy. magnetic resonance imaging, bone scan, and gallium scan were helpful in establishing the diagnosis. Cultures grew pseudomonas. The treatment required long-term intravenous antibiotics. CONCLUSIONS: pseudomonas skull-based osteomyelitis can produce a sixth nerve palsy as a result of the involvement of the clivus. Although uncommon in the post-antibiotic era, early recognition, appropriate diagnostic testing, and aggressive systemic antibiotic treatment might prevent permanent neurologic sequel.

10/10. Sigmoid sinus thrombosis following mastoiditis: early diagnosis enhances good prognosis.

    Sigmoid sinus thrombosis following mastoiditis is a rare, but potentially life-threatening, condition. Its treatment usually consists of systemic antibiotics and mastoidectomy. In this report, we describe a pediatric case of sigmoid sinus thrombosis following mastoiditis, presenting with nonspecific symptoms such as fever, otalgia, and headache. Diagnosis was based on magnetic resonance imaging. The patient responded very well to intravenous antibiotics with a rapid clinical improvement and complete recanalization of the thrombosed sigmoid sinus. In conclusion, mastoiditis may present few clinical symptoms. In case of treatment failure or new-onset neurologic deficit in children with acute otitis media, life-threatening complications associated with mastoiditis should be considered. early diagnosis is important, as favorable prognosis can be achieved with conservative management without performing any surgical intervention.
