The concept of palatal expansion can be viewed as an anachronism since the delivery and scope of this clinical technique has changed dramatically over the past few decades. Indeed, since the palatal complex does not exist in isolation, clinicians ought to be cognizant of how palatal expansion affects contiguous midfacial structures. Because of this structural arrangement, surgical and non-surgical palatal expansion can have clinical consequences on the dentoalveolar structures, which are dependent on bony remodeling of the maxillo-palatine complex. In addition, it can also be suggested that morphologic alterations of the maxillary air sinus might lead to functional and clinical improvements of inflammatory changes associated with rhinosinusitis. Furthermore, enhancements in the nasal airway could affect a host of other conditions, including nasal breathing and obstructive sleep apnea, etc. Therefore, the aim of this chapter is to review the effects of midfacial expansion techniques on contiguous structures, including the paranasal sinuses.
