Summary
Nasal polyposis (NP) may alter adult maxillary arch morphology, causing a shallower arch and wider angles between bone processes. These changes may lessen after surgery.
Area of Science:
- Dentistry
- Otolaryngology
- Orthodontics
Background:
- Maxillary complex morphology typically stabilizes in childhood.
- Nasal polyposis (NP) is associated with nasal tissue and sinus bone remodeling.
- Computed tomography (CT) shows flatter, shallower maxillary arches in chronic rhinosinusitis with NP patients.
Purpose of the Study:
- To investigate the effects of adult nasal polyposis (NP) on maxillary arch morphology.
- To explore potential maxillary bone remodeling in adults with NP.
Main Methods:
- Prospective study of 25 NP patients with CT scans, acoustic rhinometry, and rhinomanometry.
- Comparison with 25 control subjects' CT scans.
- Measurement of maxillary alveolar process (MAP) and palatine process of maxillary bone (MPP) angles and maxillary arch depth.
Main Results:
- NP patients exhibited shallower maxillary arches and significantly greater bilateral MAP-MPP angles compared to controls.
- These morphological differences decreased by the end of the postoperative follow-up period.
Conclusions:
- Maxillofacial development may continue into adulthood under conditions like NP.
- Nasal polyposis (NP) can induce maxillary arch remodeling in adults.
