Recovery of facial palsy after crossed facial nerve grafts.

Crossed facial nerve grafts for treating congenital or acquired permanent facial palsy were studied in 23 patients, ages ranging from 2 months to 38 years. Patients were divided into groups according to time after onset of paralysis. It is concluded that although crossed facial nerve grafts offered the possibility of reinnervation after facial palsy, the degree of recovery was critically dependent upon the time after onset of the facial palsy before the reinnervation procedure.

A comparison of palatoplasty with and without primary pharyngoplasty.

Two different procedures for treating patients with cleft palate are evaluated. The first procedure was push-back palatoplasty performed simultaneously with San Venero Roselli's pharyngoplasty before 18 months of age. The second procedure was isolated push-back displacement. Three hundred and forty-seven patients were reviewed. The two procedures were compared relative to the occurrence of velopharyngeal insufficiency (VPI), severity of insufficiency, velopharyngeal closure pattern, movement of the lateral pharyngeal walls, and the influence of age at time of operation. Fewer of the patients who received the combination procedure presented VPI, and those who did tended to have less severe VPI. The groups were similar in velopharyngeal closure patterns and in movement of the lateral pharyngeal walls. Operation after 3 years of age tended to be associated with VPI. The combination procedure was helpful in preventing palatal shortening. Successful use of the combination procedure at an early age may prevent faulty articulation patterns.

Surgical treatment of borderline velopharyngeal insufficiency using homologous cartilage implantation with videonasopharyngoscopic monitoring.

Borderline cases of velopharyngeal insufficiency were treated with homologous cartilage implants. The selection of patients and technique for this procedure are described. Videonasopharyngoscopy was used to identify a specific location on the posterior pharyngeal wall for the implant. A small cube of homologous cartilage was implanted in the selected site in order to achieve adequate closure. The preliminary nasopharyngoscopic and speech evaluation results in 10 patients, who were followed every 3 months for at least 1 year, are reported. Hypernasality and audible nasal emission were eliminated. The displacement and reabsorption of the implants that occurred was minimal and did not affect velopharyngeal closure. Homologous cartilage, which is inexpensive and easy to obtain, appears to be a good option for implantation in the posterior pharyngeal wall in borderline cases of velopharyngeal insufficiency.

The San Venero Roselli pharyngoplasty: an electromyographic study of the palatopharyngeus muscle.

Electromyography of the palatopharyngeus and salpingopharyngeus muscles was performed in three groups: normal subjects, subjects with cleft palate before surgical treatment, and subjects with repaired palatal clefts incorporating the San Venero Roselli pharyngoplasty. Results suggested that the salpingopharyngeus muscle is inconsistently present in man. The palatopharyngeus is primarily concerned with swallowing and is not active during velopharyngeal closure. Its activity is not affected by the San Venero Roselli procedure. The surgical approximation of this muscle may be advantageous because of its antagonistic action to the levator veli palatini.
