[Partial glossectomy assisted with temperature-controlled radiofrequency for treating macroglossia].

OBJECTIVE: To study the clinical efficacy of partial glossectomy assisted with temperature-controlled radiofrequency for treating macroglossia. METHODS: There were 4 patients performed this procedure. We took a rhombus shape incision in the middle of the tongue and performed a wedge excision. RESULTS: The mouth can close entirely in all of patients and there weren' t hemorrhage and obviously swollen; Tongue's sensory function hadn't disturbance. Masticate function were normal. One patient still had the symptom that tongue lied outside the oral cavity occasionally after operation. The symptom was disappeared after Temperature-controlled radiofrequency (TCRF) ablation. All of patients' parent were satisfied with the results. CONCLUSIONS: Partial glossectomy assisted with temperature-controlled radiofrequency for treating macroglossia is an effective, much safer and less invasive procedure without obvious adverse reactions. There are better prospects for applying.

[The inherent liability to infection of various tissue for urethra reconstruction].

OBJECTIVE: Observing the long-term results of reconstructed urethra to reduce the postop infection rate of hypospadias. To explore the standard of selecting tissue for urethra reconstruction by comparing the different inherent liability to infection in use of different kinds of tissue for urethra reconstruction. METHODS: Neo-urethra inner wall and normal urethra were observed through urography and urethroscope. The tissue section of neo-urethra, normal urethra and tissue for urethra reconstruction were observed through light microscope, scanning electron microscope and transmission electron microscope. RESULTS: The structure and liability to infection of neo-urethra made of bladder mucosa, buccal mucosa or skin never changed after long time. Metaplasia never took place in neo-urethra. CONCLUSIONS: The structure and liability to infection of neo-urethra were the same as those of the congeneric tissue. Bladder or buccal mucosa is the best tissue for urethra reconstruction considering urethra microenvironment. Neo-urethra made of skin is more liable to infection by nature. The best opportunity of hypospadias operation should be before puberty.
