ABSTRACT
Figure 18.2 A foreign body (elastic band) in the right nasal cavity. The arrow points to the inferior turbinate
Figure 18.3 The CT scan of a homeless adult who was assaulted. A foreign body (short arrow) was discovered in the right nasal cavity. Note the multiple left facial fractures (long arrows)
Figure 18.4 Endoscopic appearance of the foreign body in the nose
Figure 18.5 A rhinolith in the right nasal cavity of an adult who was born with bilateral clefts of the lip and palate which were successfully repaired in infancy
Figure 18.6 The CT appearance of the rhinolith in the nasal cavity of the patient shown in Figure 18.5
Figure 18.7 A foreign body (short arrow) was discovered incidentally in the floor of the left nasal cavity on routine endoscopy in a patient with nasal allergies. It felt metallic with a suction tip. The long arrow points to the inferior turbinate
Figure 18.8 A CT scan of the patient in Figure 18.7 showed that the foreign body is the tip of a dental implant placed a few years before. The patient had no related symptoms
Figure 18.9 A right naso-alveolar cyst (short arrow) bulging in the floor of the nose. The long arrow points to the inferior turbinate
Figure 18.10 A bony mass (short arrow) seen in the anterior roof of the left nasal cavity in an adult who complained of left nasal blockage. The long arrow points to the tip of the middle turbinate
Figure 18.11 A close-up view of the bony mass shown in Figure 18.10
Figure 18.12 The CT scan of the patient shown in Figures 18.10 and 18.11. The mass proved to be a very large agger nasi cell. Resecting its medial half improved the nasal breathing
Figure 18.13 A teenage girl’s CT scan ordered prior to dental work. Note the opacities (short arrow) and the bony erosion (long arrow) of the left maxilla. The patient had no rhinologic symptoms and the nasal endoscopy was negative
Figure 18.14 The oral examination of this girl revealed a firm nonsymptomatic bulge on the left side of the hard palate of which she was unaware. A biopsy gave the diagnosis of a cementifying ossifying fibroma
Figure 18.15 This adult male complained of recurrent right frontal sinusitis following a motor vehicle accident, several months before, in which he sustained multiple right facial fractures. Endoscopy showed scarring and blockage of the right frontal recess (short arrows). The CT scan confirmed the presence of a blocked right nasofrontal duct. The long arrow points to the middle turbinate
Figure 18.16 The CT scan of an adult female with right chronic sinusitis resistant to treatment. Note the absence of the middle turbinate. The arrow points to the eroded medial wall of the maxilla. Endoscopy revealed crusting and an absent right middle turbinate. The patient had not had any previous nasal surgeries. A biopsy confirmed the clinical impression of Wegener ’s granulomatosis
Figure 18.17 A totally blocked right nasal cavity in a patient with a nasopharyngeal adenocarcinoma treated a few months before by radiation and chemotherapy. The short arrows point to the obstructing pathology. The long arrow points to the middle third of the inferior turbinate
Figure 18.18 Two CT scan cuts of the patient shown in Figure 18.17. The short arrow points to the blockage of the midright nasal cavity, which proved to be due to scar formation. The long arrow points to the slightly stenotic right posterior choana noted in a more posterior cut
Figure 18.19 The endoscopic appearance of the right nasal cavity of a patient who complained of a postnasal drip. It showed a bony mass hanging from the sphenoethmoid recess into the nasopharynx
Figure 18.20 This same mass (short arrow) was also seen from the left side of the nose. The long arrow points to the posterior edge of the vomer
Figure 18.21 The CT scan of the patient shown in Figures 18.19 and 18.20. The arrows point to the mass, seen in the nose (short arrow) and in the nasopharynx (long arrow). It proved to be a part of the right middle turbinate which was partially cut but not resected during a previous surgery and subsequently must have been pushed into the nasopharynx. The postnasal drip did not improve after its endoscopic resection!
