Between unity and disparity: current treatment protocols for common orofacial clefts in European expert centres.

Abstract

There is considerable variability in the management of common orofacial clefts across Europe, reflecting differing opinions on optimal treatments. An updated overview of treatment protocols for orofacial clefts across 26 expert centres in the European Reference Network CRANIO is presented here. A structured questionnaire was distributed to map the surgical protocol and additional standard procedures for cleft palate (CP), unilateral cleft lip and palate (UCLP), and bilateral cleft lip and palate (BCLP). A surgical protocol was defined as the unique combination of a sequence of standard surgeries, their timing, and the surgical techniques employed. Overall, 33 unique surgical protocols for CP, 54 for UCLP, and 51 for BCLP were identified. Notable findings included the trend towards early hard palate closure, uniform timing of lip closure, and the popularity of primary cleft rhinoplasty. Nevertheless, practice variations were most pronounced in the timing of alveolar closure, the number of standard surgeries, and the application of additional standard procedures. This study highlights the diversity of treatment protocols across Europe, despite considerable convergence of treatment practices over time. To allow for further convergence, establishing objective criteria for protocol selection, adequate documentation of customizations, and consensus on the terminology of surgical techniques, are necessary.
