Figure 6.7 Tympanogram type B of the same case, typical of middle ear effusion. Figure 6.8 Right ear. Grade I atelectasis. The tympanic membrane is markedly thinned due to partial resorption of the lamina propria. The incus is seen in transparency. Pure tone audiogram is normal Fig. 6.9 , whereas the tympanogram has a very high compliance Fig. 6.10 . As the tympanic membrane is mobile with the Valsalva maneuver, insertion of a ventilation tube is not indicated.

Figure 10.4 The infralabyrinthine apical type of petrous bone cholesteatoma originates from the infralabyrinthine or apical compartments. When it originates from the former, it extends into the petrous apex. In some cases it may grow towards the sphenoid sinus or the horizontal portion of the internal carotid artery.

Figure 9.1 Right ear. Congenital cholesteatoma seen as a white retrotympanic mass causing bulging of the posterior guadrants of the tympanic membrane. Neither drum perforation nor bony erosion are detected. Figure 9.2 Right ear. A small whitish retrotympanic mass is clearly seen. The mass lies posterior to the malleus type A2 . By definition, a cholesteatoma is considered congenital when the tympanic membrane is intact and there is no history of otorrhea or previous ear operations including...

Hyperemic Tympanic Membrane
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....

Tympanic Membrane
Figure 6.5 Right ear. Grade I atelectasis with the malleus slightly medialized. An epitympanic retraction pocket is also seen. Middle ear effusion with yellowish color can be appreciated. Pure tone audiogram revealed a 40-dB conductive hearing loss Fig. 6.6 , whereas the tympanogram was type B, i.e., typical of middle ear effusion Fig. 6.7 . In this case, the insertion of a ventilation tube is indicated to avoid further retraction of the tympanic membrane, to aerate the middle ear, and to...

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
Figure 7.27 Right ear. 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.

Otoscopy Facial Nerve
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...
