Bilateral oblique facial cleft.

An extremely rare case of bilateral oblique facial cleft is presented. This should be classified as a bilateral oroocular Type I cleft according to Boo-Chai's classification and a bilateral No. 4 cleft according to Tessier's classification. Except for this deformity, the patient was normal and healthy. Corrective surgical procedures were carried out between the ages of 4 months and 18 months to repair the left and right clefts, remove an abscess caused by the remnant of the lacrimal canal, and repair the cleft palate. The patient is now making a good recovery. Bone graftings or craniofacial osteotomies may be recommended at a later age.
