Figure 4: a. Left nasal cavity of a patient having been subjected to extensive (“radical”) sinus surgery for chronic rhinosinusitis leading to “empty nose syndrome”.
b. Right nasal cavity of a patient having been subjected to a rhino-neurosurgical intervention for craniopharyngeoma with application of a naso-septal flap. Irrespective to use of a “reverse flap” for amelioration of postoperative crusting, significant atrophic rhinitis is seen.
