ABSTRACT
OBJECTIVE: This paper presents a method for treating maxillary neuralgia, the second division of trigeminal nerve. METHOD: One hundred and thirty six cases with 136 trigeminal neuralgia were treated from 2004 to 2011. All patients were treated with endoscopic surgery at the pterygopalatofossa through approach to the maxillary sinus for resecting maxillary nerve and infraorbital nerve. RESULT: One hundred and eighteen patients were relieved after operation and no recurrence of neuralgia was occurred after 2 to 8 years of follow-up. CONCLUSION: This method had the advantages of avoiding to operate craniotomy with no complications, which was performed easily with valid efficacy.

OBJECTIVES: Expression of vascular endothelial growth factor C (VEGF-C)and vascular endothelial growth factor receptor-3 (VEGFR-3) in laryngeal squamous carcinoma and its relationship to lymph node metastasis were investigated. METHODS: VEGF-C and VEGFR-3 gene expression in 30 cases of normal laryngeal mucosa tissue (NLM), primary laryngeal carcinoma cell carcinomas (PLC) and cervical lymph nodes (CLN) was examined by reverse transcription polymerase chain reaction (RT-PCR). Protein levels of VEGF-C expression were determined by immunohistochemical staining in 60 cases of PLC. RESULTS: Expression of VEGF-C and VEGFR-3 different among NLM, PLC and CLN in the same patient. In PLC, expression was significantly higher in lymph node positive group than in the lymph node negative group and associated with histological grade of differentiation; Expression of VEGF-C and VEGFR-3 was not linked with age, sex, site or T stage. CONCLUSIONS: A close correlation was found between VEGF-C/VEGFR-3 expression and lymph node metastasis in PLC, suggesting a role in metastasis of laryngeal carcinomas.
