Tympanic Membrane Pathology

Figure 10.5 The apical type of petrous bone cholesteatoma is a rare congenital lesion. It may solely involve the apical compartment, causing erosion of it. It may involve the trigeminal nerve or more posteriorly the posterior cranial fossa. It may also engulf the horizontal portion of the internal carotid artery.

Tympanic Membrane Sclerosis

Figure 10.14 Left congenital supralabyrinthine petrous bone cholesteatoma with extension towards the apex. Otoscopy is negative. The patient complained of progressive facial nerve paralysis of 5 years' duration as well as conductive hearing loss. Figure 10.16 CT scan of the case presented in Figure 10.14. Axial view showing cholesteatoma extending into the petrous apex. Figure 10.16 CT scan of the case presented in Figure 10.14. Axial view showing cholesteatoma extending into the petrous apex....

Figure 11.5 The class C3 tumor involves the horizontal segment of the carotid. Figure 11.6 The class C4 tumor grows to the anterior foramen lacerum and extends to the cavernous sinus. Class D indicates intracranial extension of the tumor. This might be extradural De or intradural Di . Figure 11.7 Left ear. Glomus tympanicum or class A tumor. The small red mass behind the anteroinferior quadrant is localized on the promontory and does not extend towards the hypotympanum see Fig. l1.7 . Figure...

Tympanic Membrane Pathology

Figure 8.9 CT of the previous case, coronal view. The cholesteatoma is located in the epitympanic area. The middle ear is free. Figure 8.11 Left ear of the same patient. Cholesteatoma with marked erosion of the scutum and epidermization of the attic and mesotympanum. The cholesteatoma debris was partially cleaned. The residual pars tensa shows tympanosclero-sis. Intraoperatively, the ossicular chain was absent. The oto-scopic view of the left ear is apparently more advanced than the right ear....

Figure 6.10 Tympanogram of the same case, type AD according to the classification of Liden-Jerger, 1976 see text . Figure 6.11 Left ear. Grade II atelectasis with marked epi-tympanic retraction. The tympanic membrane touches the incus. The malleus is medialized. Air-fluid levels are seen in the anteroinferior quadrant. The insertion of a ventilation tube is necessary to restore normal conditions. Figure 6.11 Left ear. Grade II atelectasis with marked epi-tympanic retraction. The tympanic...

Tympanic Membrane Perforation

Retraction Pocket

Large tympanic membrane perforation. The anterior drum residue shows tympanosclerosis. The ossicular chain is difficult to identify because of the presence of epidermization at this level. The round window is visible. A staged tympanoplasty is also indicated in this case. Figure 7.28 Right ear. Granulomatous otitis media. A roundish mass fills the middle ear. Serous otorrhea is present. Figure 7.27 Right ear. Large tympanic membrane perforation. The anterior drum residue...

Meso- and epitympanic retraction pockets that adhere to the head of the malleus, the partially eroded long process of the incus, and the incudostapedial joint. A ventilation tube has been inserted in the anterior quadrant to avoid further retraction that might lead to cholesteatoma. Figure 6.26 Right ear. Large mesotympanic...

Figure 3.55 Nasopharyngeal carcinoma extending into the middle ear and external auditory canal. A polypoid mass infiltrates the tympanic membrane and partially fills the external auditory canal see CT scan, Fig. 3.56 and MRI, Fig. 3.57 . The patient was considered inoperable and was referred to radiotherapy. Figure 3.56 The CT scan demonstrates marked infiltration of the nasopharynx, the pterygoid muscles, and the petrous apex. Figure 3.56 The CT scan demonstrates marked infiltration of the...

Figure 3.37 CT scan of the same case as in Figure 3.36. The middle ear and mastoid are occupied by an isointense mass, A frozen section obtained during surgery revealed the presence of histiocytosis X. The patient was referred to a specialized center for appropriate staging and therapy with cyto-toxic drugs and...

Otoscopy Facial Nerve

Fungal Ear Infection Otomycosis

The good fortune of otology resides in the fact that in most cases a diagnosis can be established through careful otoscopic examination the tympanic membrane is the window to the middle ear. Otoscopy constitutes the first phase in the examination of the patient. The initiation of the young otologist begins with this basic step. Colleagues of my generation will recall the long months of training which were necessary to understand and identify something in the depths of a narrow, tortuous, and...
