With the help of nasopharyngoscopy, it was possible to delineate specific morphologic changes in the palates of patients with velopharyngeal insufficiency, without an overt cleft and without the triad of symptoms of submucous cleft palate, visible through the oral cavity. Such malformations are part of the broad spectrum of the faulty midline mesodermal fusion of the palate. This anomaly is aptly called occult submucous cleft palate, because it can only be detected by viewing the functioning palate from the nasal surface. The musculus uvulae is either absent or deficient and is frequently associated with some degree of muscular diastasis that does not involve the oral surface. Like the cleft of the secondary palate, the submucous cleft palate often occurs as part of a generalized syndrome of multiple malformations.

A total of 202 patients with pharyngeal flaps were assessed with nasopharyngoscopy and multiview fluoroscopy to determine the role of lateral pharyngeal wall movement postoperatively. Variations in the construction of flaps resulted in three categories: namely, a long narrow flap with a high insertion, a short broad flap with a low insertion, and an intermediate-size flap that is inserted in a position somewhere between the first two. It was found that in all cases where there was no evidence of velopharyngeal insufficiency, the sole determiner of velopharyngeal closure was the medical excursion of the lateral pharyngeal walls to the sides of the flap. In flap failures, the causes for velopharyngeal insufficiency were inappropriate degree, level, and symmetry of the lateral pharyngeal wall motion. The success of pharyngeal flap surgery depends largely on the preoperative assessment of the velopharyngeal mechanism and the choice of a type of pharyngeal flap that will best assist closure of the velopharyngeal port during speech.

We report a case of Wernickes sensory aphasia, caused by a localized cerebritis of the left temporal lobe. The condition developed in the second week after an esthetic rhinoplasty. There was an associated small abscess in the right inner canthal area.

Additional experience with the chondrocutaneous flap in the repair of auricular defects showed that (i) the entire medial surface of the auricle can be easily and rapidly exposed through this approach, and (ii) the transhelical scar on the lateral surface of the ear remains inconspicuous. The skin of the lateral surface of the ear is similar to that of the eyelids and forms flat, smooth scars which do not hypertrophy. Furthermore, these scars are hidden under the curl of the helix. Through this approach, correction of the protrusion can be accomplished by any method or combination of methods which call for manipulation on the medial surface of the auricle. The scar is remote from the site of manipulation of the cartilage. An additional advantage of this procedure is that it can be combined easily with a small reduction in the size of the scapha.

SummaryA procedure has been presented for the reconstruction of full thickness destruction of the oral commissure resulting from electrical burns. Major features are the translocation of orbicularis oris muscle remnants to restore muscle continuity, and the use of local skin and mucosa to provide the elements of a normal commissure.

SummaryThe history of surgical correction of the pendulous abdomen is briefly reviewed. Based on our experience in 30 consecutive cases, the method of lipocutaneous reduction is outlined, incorporating modifications of previously described techniques.
