Abstract: Objective To evaluate the efficacy and influencing factors of cranial remolding orthoses (CRO) in the treatment of infant positional brachycephaly (PB),in order to provide scientific basis for optimizing the treatment strategy of CRO. Methods A total of 63 infants with PB who received CRO treatment at the Beijing United Family Hospital from September 2018 to February 2022 were collected.Three-dimensional laser scanning technology was used to measure the Cephalic Ratio (CR),calculate the rate of head shape change.The efficacy and influencing factors of CRO treatment were analyzed. Results After CRO treatment,the CR value of infants with PB improved significantly (t=16.97,P<0.001).There was a significant difference in the treatment time among different groups of CRO onset months,with the 4- to 5-month-old age group being significantly shorter than the 8-month-old and above group (H=9.611,P<0.05).There was a negative correlation between the age of initial treatment and the rate of head shape change (r=-0.592,P<0.001).The severity of PB at the beginning of treatment was positively correlated with the rate of head shape change (r=0.498,P＜0.001).Comorbidity with plagiocephaly was correlated with the rate of head shape change (Z=-2.115,P＜0.05).Prematurity was not significantly correlated with the rate of head shape change (Z=-1.424,P>0.05). Conclusions CRO has a significant effect on the treatment of infant PB.The younger the age,the shorter the treatment time,and the more severe the PB,the higher the treatment efficiency.The treatment efficiency of infants with concurrent plagiocephaly is affected.It is recommended that pediatricians diagnose the PB as early as possible and recommend wearing CRO for treatment,especially for severe PB,to achieve better treatment outcomes.
