Maxillary sinus development in patients with cleft palates as compared to those with normal palates.
Maxillary sinusitis appears to be more prevalent in the cleft palate population than in the normal population. The increase in sinusitis may be due to the fact that the maxillary sinus develops differently embryonically in cleft palate patients than in those patients with normal palates. A double blind study was done by measuring the maxillary sinus cephalometric x-rays in cleft palate patients and then comparing them to patients with normally developed palates. The groups studied were 3 months to 20 years of age. It was concluded that in each of these groups there was no significant difference in size, shape, or rate of development of the maxillary sinus in cleft palate patients compared to the normal population. It is probable that the increased incidence of maxillary sinusitis in cleft palate patients is due mainly to the open palate with constant contamination of the nasal mucosa by food pushed into the nares and sinus ostia, resulting in maxillary sinusitis.
