Triangular flap for atypical cleft lip. A modification in design.

Standardized steps or criteria for designing a triangular flap do not always fit for all types of cleft lip repair. Some compromise among the criteria is required, especially for atypical cases, such as those with a long vertical height on the noncleft side and a short lateral lip element. In order to secure symmetry in the horizontal length of vermilion, or in the distance from the peak of the cupid's bow to the mouth corner, E' should be located as high as allowable. The ratio of the length of the vertical incision to that of the triangular base affects the final shape of the repaired lip in many ways. Since the bottom of the cupid's bow is generally gradual, slight horizontal asymmetry in the cupid's bow is usually acceptable, as compared with that of the other components.

Diagnostic value of tomography in unilateral vocal cord paralysis.

Tomographic studies were made on 56 patients with unilateral paralysis of the vocal cord. The findings were examined in relation to etiology, course, and laryngoscopic findings. In 74.1 percent of the cases, marked enlargement of the ventricle was noticed on the side of the paralysis, especially during inhalation. The paralyzed vocal cord was higher than the intact cord during phonation in 46.4 percent of the cases. The rest of the cases (53.6 percent) demonstrated no level difference between the vocal cords. The position of the paralyzed vocal cord, unilateral involvement of the cricothyroid muscle and other neck muscles were suggested as possible contributors to the findings.

A new folded pharyngeal flap. Preliminary report.

In an attempt to minimize postoperative scar contracture and shrinkage after a pharyngeal flap operation, a folded flap operation was devised. This operation was performed on 14 patients with velopharyngeal inadequacy. A superiorly-based flap was elevated from the posterior pharyngeal wall and was folded with the mucosa outside. The flap-velum connection was made through raw surfaces produced on each lateral ridge of the flap and the two penetrating incisions on the sides of the soft palate. In none of the cases did detachment of the flap or any other complications occur. This rather simple technique which aims to prevent scar contracture of the flap will permit further elaboration of the flap design-depending on the extent of velopharyngeal incompetence.
