This study evaluates 2 Techniques of Surgically Assisted Rapid Maxillary Expansion (SARME) in the treatment of maxillary transverse deficiency. Half of participants will undergo an osteotomy between the maxillary central incisors, while the other half will undergo an osteotomy between the maxillary lateral incisors and canines (bilateral osteotomies).
Surgically Assisted Rapid Maxillary Expansion (SARME) can be performed by a osteotomy between the maxillary central incisors and by osteotomies between the maxillary lateral incisors and canines (bilateral).
Both techniques treat transverse maxillary hypoplasia, but they do so with different effects on esthetics, periodontium, teeth and bone expansion.

I plan to share the data on March 24, 2020 when I going to present my Master degrees' thesis. I tried to submit an article with the data. I'm waiting for a reply
