An asynclitic birth or asynclitism refers to the position of a baby in the uterus such that the head is tilted to the side^[1], causing the fetal head to no longer be in line with the birth canal.^[2] Most asynclitism corrects spontaneously in the progress of normal labor. Persistence of asynclitism is usually a signal of other problems with dystocia.

Other abnormal birth positions include breech birth, posterior presentation, anterior presentation, and transverse presentation.

Kielland forceps are preferable obstetric forceps used in asynclitic births, for example by their sliding mechanism, availing for more appropriate adjustment of the blades. ^[2]
