He published numerous papers and a book titled Handbook of Facial Growth in 1975. After moving to Case Western, he wrote the book Essentials of Facial Growth with Dr. Mark Hans. A recent version of the book was published in 2008. Following are some of the principles that were developed based on Enlow's research.
Enlow's Counterpart Principle - The growth of any cranial or facial structure relates to other 'counterparts' in face and cranial area. ex. Maxilla and Mandible, Middle Cranial Fossa and Mandibular Ramus
Enlow's V Principle - The movement happens at the wide end of the V during growth as a result of deposition of bone inside and resorption outside.
