Abstract
Pneumocele of the maxillary sinus has been observed for the first time, to our knowledge. This abnormality probably resulted from a physiologic block to rapid equilibration of intrasinus air pressure through the major sinus ostium as a result of some abnormality producing a one-way valvular mechanism. Repeated air-trapping secondary to sneezing or autoinflation may have produced chronic distention within the maxillary sinus. Roentgenographic findings include bone dehiscence on plain films or tomograms, a normally aerated or hyperlucent sinus, and expansion of the sinus into its various anatomic recesses.
