Does maxillary arch remodeling exist in nasal polyposis?

Assessment of the relationship between palatum durum and maxillary bone in patients with nasal polyp, chronic sinusitis or septum deviation

Nasal obstruction most commonly occurs due to mucosal abnormalities and those in cartilage-bone structure such as nasal polyp, septum deviation, concha hypertrophy and chronic sinusitis in adults. Adenoid vegetation is the most prominent cause in childhood. In the present study, we aimed to investigate whether maxillary and palatal bone developments continue in patients with abnormalities causing nasal obstruction. As computerized tomography is the optimal imaging modality in nasal cavity abnormalities, CT scan findings of patients with Control nasal polyp, chronic sinusitis and septum deviation were retrospectively evaluated; and palatal curve changes were compared. In our study, it was found that maxillary bone curve was widened in adult patients with nasal polyp; this angle was further narrowed in those with chronic sinusitis; and maxillary bone curve narrowing and increase in the distance to palatal bone was smaller in patients with septum deviation than those in chronic sinusitis. In the light of these findings, we concluded that, in adults, maxillary and palatal bone developments continue in certain circumstances including nasal polyp, chronic sinusitis or septum deviation.
