The purpose of this study was to demonstrate a new application of the pressure-flow technique and to determine whether the temporal characteristics of aerodynamic data associated with single-word utterances could reliably differentiate speakers with adequate palatopharyngeal closure from those with inadequacy. The groups included 10 normals, 20 patients(More)
This article illustrates an application of confirmatory factor analysis, using the LISREL program, to retrospective analysis of rating data common in health professions education. We begin with specification of a causal model reflecting the multitrait-multimethod design of a surgical house-officer ranking system. The model is then tested using data provided(More)
In the preceding article, patients undergoing von Langenbeck palatoplasty without reconstruction of the levator veli palatini muscles were compared to patients undergoing the identical procedure, but with intravelar veloplasty. Palatoplasty included repair of both hard and soft palate, tension-free approximation of mucoperiosteal and soft palate flaps, and(More)
Fifty-two patients with velopharyngeal incompetency without overt cleft palate underwent pharyngeal flap surgery. Surgery included exploration of the soft palate and reconstruction of the levator muscles. Four patients had a completely normal hard and soft palate. In two patients, the palatal musculature was normal but a U-shaped defect of the posterior(More)
The complications of 196 patients who underwent primary palatoplasties at North Carolina Memorial Hospital between 1963 and 1983 were reviewed. The von Langenbeck technique was utilized in 50 percent of the patients, the Wardill-Kilner technique in 45 percent, and the Dorrance technique in 5 percent. Intravelar veloplasties were performed in 34 percent of(More)
Patients with velopharyngeal inadequacy require structural modification of the velopharyngeal area by a prosthesis or by surgery in order to provide a mechanism for intelligible speech. The superiorly based, high-attached, lined pharyngeal flap was chosen for the treatment of velopharyngeal incompetency and the operative technique was described. Results(More)
