ABSTRACT
Figure 7.4 A left middle turbinate with a shorter neck (short arrow). Note its polypoid protrusion anterior to the neck (long arrow)
Figure 7.5 A very large left middle turbinate noted incidentally. It proved to be a concha bullosa on the CT scan
Figure 7.6 The CT scan of the subject in Figure 7.5. The arrows point to the bilateral cellular middle turbinates noted incidentally in a subject with no sinus complaints
Figure 7.7 A large right middle turbinate with a short neck
Figure 7.8 The CT scan showed that the large size of the middle turbinates is due in this case to cancellous bone rather than an air cell, a rare variant
Figure 7.9 A paradoxical left middle turbinate with its lateral convexity. The arrow points to the septum
Figure 7.10 A large left middle turbinate, bullous in its upper part only, is also paradoxical
Figure 7.12 A normal-looking anterior half of a right middle turbinate (short arrow) with an aerated (or cellular) posterior half (long arrow). The arrowhead points to the septum
Figure 7.13 A left middle turbinate which is cellular in its upper three-quarters only
Figure 7.14 A right middle turbinate with a congenital ‘cookie-bite’ deformity which is of no clinical significance
Figure 7.15 A larger congenital defect in a left middle turbinate, of no clinical significance
Figure 7.16 An anomalous right middle turbinate with a deep concavity laterally (short arrow). The long arrow points to the uncinate process, and the arrowhead to the ethmoid bulla

Figure 7.18 A groove in the belly of a right middle turbinate
Figure 7.19 A deep and longer groove in the belly of a left middle
Figure 7.20 A split left middle turbinate. The lateral half, if followed endoscopically, leads to the tail of the middle turbinate, unlike an uncinate process which may have almost the same appearance, but which leads to the inferior turbinate if followed
Figure 7.21 A dimple on the anterior part of the right middle turbinate
Figure 7.22 A left concha bullosa with an inferior ostium
Figure 7.23 A left concha bullosa with a lateral ostium
Figure 7.24 A left middle turbinate with a dimple (short arrow) and a vertical groove (long arrow) on its lateral aspect. The arrowhead points to the bulla ethmoidalis
Figure 7.26 The CT appearance of the protrusion shown in Figure 7.25
Figure 7.27 The tail of the left middle turbinate (short arrow). Note the vascularity (long arrow) of the sphenoethmoid recess, a normal but uncommon variant. The arrowhead points to the septum
Figure 7.28 A polyp discovered incidentally on the lower part of the left middle turbinate
Figure 7.29 A polyp on the tail of the right middle turbinate (short arrow). Note the violaceous discoloration, a normal variant, which is visible in the tail of the left middle turbinate (long arrow). The arrowhead points to the upper part of a defective vomer in a patient with a bilateral cleft palate
Figure 7.30 A polypoid tip of the tail of the right middle turbinate, similar to the more commonly seen polypoid posterior tips of inferior turbinates
