Establishment of animal model of rectus abdominis musculoperitoneal flap to reconstruct tongue defect / 华西口腔医学杂志

<p><b>OBJECTIVE</b>This study aims to investigate the feasibility of tongue reconstruction by a rectus abdominis musculoperitoneal flap with neurovascular pedicled in a canine model.</p><p><b>METHODS</b>Twelve Beagle dogs were enrolled to the experiment. The animals were randomly divided into thee groups, two of which (group A and B) had nerve anastomosis. The left sides were experimental sides, whereas the right sides were control sides. Twelve weeks after operation, electrophysiological test was performed to detect hypoglossal nerve latency amplitude and conduction velocity as well as to evaluate the reinnervation of the rectus abdominis musculoperitoneal flap.</p><p><b>RESULTS</b>Among the 12 Beagle dogs, nine animal tongue reconstruction models by rectus abdominis musculoperitoneal flap with neurovascular pedicled were successful, whereas one male Beagle dog died from ventral hemia 3 d after the operation, two female rectus peritoneal flaps were abandoned because their arterial anatomy differed from the male, which was not ideal. Hypoglossal nerve conduction velocity of group A and B were restored to the normal side of the 40%, 30%.</p><p><b>CONCLUSION</b>Animal models of tongue reconstruction can be established by a rectus abdominis musculoperitoneal flap with neurovascular pedicled in Beagle dogs. Denervated rectus abdominis musculoperitoneal flap can regain hypoglossal nerve innervation. Hypoglossal nerve functions partly recover.</p>

McCune-Albright syndrome: A case report and review of literatures / 实用口腔医学杂志

Objective:To report a case of McCune-Albright syndrome (MAS). Methods:Investigated one case's clinical data of McCune-Albright syndrome and reviewed related literatures. Analyzed the cause of disease,clinical manifestation, diagnosis, treatment and prognosis. Results: The diagnostic criteria of MAS are the fibrous dysplasia of bone (FD), in addition to at least a kind of typical hypercrinemia, and (or) special café-au-lait skin spots. A definite diagnosis can be made by discovering the mutation of Gs α-gene in cyst fluid from the ovarian follicle and exceptional bone tissue by gene diagnosis. Conclusion:MAS is a rare disease in clinic and the most of domestic doctors don't know it yet, so it is easy to be misdiagnosed or missed diagnosis. There is no specific treatment for MAS. We must consider it when encounter these patients with sexual precocity as well as with café-au-lait skin spots, and it will be helpful to treat by earlier discovery.
