Introduction: Post-orthognathic surgery operative diets are typically restricted to allow healing. However, oral intake is essential to provide for nutrition and patient comfort. Limited data exists to evaluate postoperative diet protocols. This study evaluates a large series of diet protocols across different centers to determine the range of diets that are recommended.
Methods: An electronic search was carried out for "orthognathic surgery diet". Sites with quantifiable postoperative diet duration recommendations were included.
Results: Out of 58 protocols that were included, 37 were located in the US (63.8%). Thirty-nine protocols were from OMFS (67.2%), 12 from dental centers (20.7%), 4 from plastic surgeons (6.9%) and 3 unspecified (5.2%). Diets fell into 7 categories, ranging in dietary restriction from most to least restrictive: 1) liquid diet only for 4-6 weeks (12.1%), 2) liquid diet for 2-4 weeks followed by soft diet for 2-6 weeks (41.4%), 3) liquid diet for 1-2 weeks, then no chew for 2 weeks, then soft diet for 2-4 weeks (8.6%) 4) no chew for 4-8 weeks followed by soft diet for 6-8 weeks (3.4%), 5) no chew diet for 4-6 weeks (13.8%), 6) no chew diet for 1-2 weeks, then soft diet for 1-2 weeks (6.9%), 7) soft diet only for 4-6 weeks (13.8%). There were no significant patterns observed across different geographical regions or specialties.
Conclusion: This study demonstrates the range of diet protocols following orthognathic surgery used across the world. More studies are needed to determine whether restricted diets compensate for their stringency with better outcomes.
