Nasal polyposis is a common disease of which little is currently known. Recent studies have shown up-regulation of several proangiogenic factors. The aim of this study was to assess and quantify how much angiogenesis occurs in nasal polyps and therefore whether angiogenesis is involved in the etiology of polyposis. ⋯ These results show no active angiogenesis occurring in the polyp or changes in capillary bed architecture, although capillaries seem more edematous in the polyp. As the capillary supply increases in line with the physiological needs of the growing polyp, we conclude that angiogenesis is not a driving force in the etiology of nasal polyposis.

This study was performed to present a series of patients who experienced anterior palatal sensory impairment after nasal septal surgery. This phenomenon has not been reported in the English literature to date. ⋯ Sensory impairment of the anterior palate may result from surgery of the nasal septum and appears to be associated with chisel of the maxillary crest. Cautery should be avoided near the nasopalatine foramen. The relevant surgical anatomy of the nasopalatine nerve is reviewed and discussed in the context of these cases.
