ABSTRACT
Figure 10.1 The common mucosal band (short arrow) between the vomer and the left torus tubarius in a patient with an isolated acute nasopharyngitis. Note the necrotic membrane (long arrow)
Figure 10.2 A similar but wider and shallower band on the right
Figure 10.3 The band here is totally absent
Figure 10.4 A vomerine membrane. Note the absence of the band on the right side
Double bands on the right side
Figure 10.6 More prominent double bands on the left side (short arrows). Note the anterior one which inserts on the tail of the left middle turbinate (long arrow)
Figure 10.7 Large adenoids (short arrow) invading the left posterior choana, hiding the eustachian tube orifice. The long arrow points to the posterior edge of the vomer and the arrowhead to the tail of the inferior turbinate
Figure 10.8 A mild left posterior choanal stenosis noted incidentally in an asymptomatic subject. The short arrow points to the left torus tubarius and the long arrow to the tail of the inferior turbinate
Figure 10.9 A symptomatic right choanal stenosis in a patient who re-stenosed after corrective surgery for a total bony atresia
