The oblique facial cleft: a 20-year follow-up.

A 20-year follow-up is presented of a patient with an oblique facial cleft, first reported in 1970. The classification of such clefts, proposed at that time, is reviewed in relation to the Tessier classification and the long-term results of surgery reported.

Primary repair of the unilateral cleft lip nose in the Oriental: a 20-year follow-up.

The unilateral cleft lip nasal deformity is corrected as a primary procedure with the lip repair. The abnormal attachment of the alar base is first released by an incision along the superior buccal sulcus and piriform margin. There is no intercartilaginous incision. Basically, we use the Brown-McDowell technique with the addition of an alar rim incision. Undermining of the ala between the two incisions is carefully and adequately done, splitting it into two layers. The first is a skin and the second, a chondrocutaneous (vestibular skin) layer, which is handled as a single unit, thus enhancing its vascularity. This second layer is a bipedicle flap with a broad medial pedicle and a narrow lateral pedicle at the alar base. When the alar base is rolled into its normal position, the chondrocutaneous unit hinging on its two pedicles counterrotates, correcting the subluxation of the ala, a major component of the cleft lip nasal deformity. We depend on the normal position of the alar base, the postoperative scar tissue, and the inherently thick nostril wall in the Oriental to keep the alar dome up. No transfixion sutures are used. Ten consecutive patients are shown 20 years after surgery. All had one operation only. None showed any disturbance of nasal growth.

The management of ala ptosis in Oriental rhinoplasty.

We use the term ala ptosis to describe a condition in which the nostril sidewall is bulbous with overhanging of the alar margin. This hides the columella from view, especially in profile. The management of ala ptosis in Oriental rhinoplasty is done in two steps, i.e., to reduce the bulbous nostril sidewall by manipulating the alar cartilage and to reduce the alar margin to a gentle, graceful curve by means of selective rim excision after wide undermining of the ala. The definitive alar margin runs more or less parallel to the white roll of the upper lip.

Blepharophimosis with associated cup-lop ears.

Blepharophimosis is a rare congenital triad consisting of epicanthus inversus, blepharoptosis, and a wider than normal intercanthal distance. Attention has recently been drawn to abnormalities of the eyebrow and the poorly developed nasal bridge. I record 9 cases of blepharophimosis associated with cup-lop ears seen over the last 15 years. These include a father and his 4 children.
