Introduction: Muscle contraction generated by electrical impulses simultaneously originating from two different neural sources may be an interesting treatment alternative for long term facial palsy. An experimental model was designed to compare single and dual innervation of the gastrocnemius muscle (GM) in rats.
Methods: Fifty adult Wistar rats underwent transection of their right peroneal nerve and were divided into five groups (n = 10): control (C), tibial nerve section (TS), tibial nerve primary end-to-end neurorrhaphy (PEE), tibial nerve primary repair associated with end-to-side peroneal-to-tibial nerve transfer (PRES), and tibial nerve repair by convergent end-to-end (CEE) neurorrhaphy between the proximal stumps of the tibial and peroneal nerves to the distal stump of the tibial nerve.
The aim of this study was to evaluate swallowing, speech and quality of life in patients undergoing surgery for malignant tumors involving soft palate. We performed a cross sectional study of 23 patients (aged 32-80 years), submitted to soft palate resection, free of disease for at least 1 year. Primary closure of the surgical defect was performed in 5 patients (21.
