The Implications of Laterality in Unilateral Cleft Lip Reconstruction: A Global Survey of Cleft Surgeons

ObjectiveTo explore the impact of directional laterality in complete Unilateral Cleft Lip (UCL) amongst the global cleft surgeon communityDesignCross-sectional survey study.SettingGlobal distribution of online survey distributed in English and Spanish.ParticipantsCleft surgeons from around the world.Main outcome measuresSurvey participant perception of the impact of laterality on: (1) cleft presentation (2) surgical challenge and (3) surgical outcomes.ResultsResponses were received from 453 cleft surgeons located in 54 countries around the world. 221 (49%) had previously considered differences in patients presenting with a left- versus right-sided UCL. 95 (21%) considered right-sided clefts more difficult to reconstruct, 37 (8%) reported left-sided clefts to be more difficult and 321 (71%) reported no difference in difficulty between the cleft sides. Higher volume cleft surgeons, characterised by those reporting cleft as their principal area of practice and performing >20 cleft operations per year, were more likely to have both previously considered differences in laterality in cleft and to report right-sided unilateral cleft lip to be more difficult to primarily reconstruct. 395 (87%) did not consider surgical outcomes to be influenced by cleft laterality.ConclusionsThis survey reports perceptions on cleft laterality from a large body of global surgeons and suggests a trend for increased difficulty in right-sided compared to left-sided cleft lip reconstruction, where such laterality-associated difficulty is perceived.
