A pharyngeal groove (or branchial groove, or pharyngeal cleft^[1]) is the counterpart of the branchial pouch on the ectodermal side.

The first pharyngeal groove produces the external auditory meatus.^[2] The rest (2, 3, and 4) are overlapped by the growing 2nd pharyngeal arch, and form the floor of the depression termed the cervical sinus, which opens ventrally, and is finally obliterated.
