1/6. Masked diabetic mastoiditis.Seven cases of elderly diabetics suffering from ths so-called 'malignant external otitis' are presented. Chandler (1968) and others consider that this disease is localized to the external ear canal. We do not agree and believe that it is due to a masked middle-ear infection extending through the tympano-mastoid cells to the mastoid process, sparing the antrum and bulging into the floor of the external meatus. In time, extension to petrous apex results in petrositis and a fatal end in many cases.- - - - - - - - - - ranking = 1keywords = petrositis (Clic here for more details about this article) |
2/6. 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.- - - - - - - - - - ranking = 1keywords = petrositis (Clic here for more details about this article) |
3/6. Nonspecific necrotizing petrositis: an unusual complication of otitis in children.Three cases of an unusual form of suppurative chronic otitis media in children 2 and 3 years old are presented. The clinical feature common to all cases was otorrhea, beginning at the first months of life, with a silent evolution to a complete peripheral facial paralysis. In one case the facial paralysis was bilateral. The treatment applied was surgical: subtotal petrosectomy. The surgical findings were bloody granulation tissue, sequestering completely the otic capsule. The facial nerve was destroyed almost the total length of the Fallopian canal in all cases. The histopathologic examination revealed a destructive and nonspecific chronic inflammatory process. The culture showed Gram-negative organisms, such as pseudomonas aeruginosa and proteus mirabilis. Etiologic aspects involved in the process are discussed and the name non-specific necrotizing petrositis is suggested to individualize this rare form of otitis which, with morbidity, leads to severe complications such as facial paralysis and deafness.- - - - - - - - - - ranking = 5keywords = petrositis (Clic here for more details about this article) |
4/6. Gradenigo's syndrome revisited.In 1907, Gradenigo described the syndrome of constant otorrhea, headache, and diplopia which he attributed to inflammation of the petrous apex. In 1908, Baldenweck described the pathology of petrositis. Renewed interest in this syndrome occurred 20 years later through the papers of Eagleton, Kopetsky and Almour, Frenckner, and Ramadier. Various surgical approaches were described during the 1930's by Eagleton, Frenckner, Ramadier, and on this continent by Lempert. In 1932, Lillie and Williams reported two cases of petrositis from the Mayo Clinic. Stacey Guild in 1935 and John Lindsay in 1938 reported on the pathology of petrositis in post mortem cases. After the advance of chemotherapy, Thornell and Williams in 1946, emphasized the need for adequate surgical drainage. In 1958 DeWeese reported three cases of petrositis with the admonition "Lest we forget that this condition still occurs". The purpose of this paper is to present a case of petrositis and to stress the importance of modern radiological techniques in its diagnosis and management.- - - - - - - - - - ranking = 5keywords = petrositis (Clic here for more details about this article) |
5/6. Gradenigo's syndrome: CT and MRI findings.We report the case of an 8-year-old girl with Gradenigo's syndrome. Involvement of the petrous portion of the left temporal bone was demonstrated by CT and an inflammatory lesion of the left petrous apex was clearly shown by MRI, which is useful in diagnosis and management of apical petrositis.- - - - - - - - - - ranking = 1keywords = petrositis (Clic here for more details about this article) |
6/6. Middle ear infection and sixth nerve palsy.Three cases of patients with acute middle ear infections complicated by a sixth nerve palsy are described. The possible causes of sixth nerve palsy in such cases are discussed. We propose that where there is a sixth nerve palsy without petrositis and without raised intracranial pressure, it can arise as a result of spreading phlebitis along the inferior petrosal sinus from the lateral sinus.- - - - - - - - - - ranking = 1keywords = petrositis (Clic here for more details about this article) |
