Role of human papillomavirus in head and neck squamous cell carcinomas / 华西口腔医学杂志

Human papillomavirus (HPV) is a major causative agent of cervical cancers. Over the past several decades, increasing number of studies established strong association of HPV with a subset of head and neck squamous cell carcinomas (HNSCCs). In the present study, we reviewed evidence, including epidemiology, carcinogens, diagnosis, treatment, and prognosis, showing that HPV-positive HNSCCs exhibit a variety of distinct characteristics for understanding tumor biology and improving cancer treatment.

The clinical study of complete remaining parotid fascia in parotidectomy / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To introduce a new method of complete remaining parotid fascia in parotidectomy, preventing Frey's syndrome.@*METHOD@#Thirty-five patients with benign tumor in the parotid gland were treated by remaining parotid fascia. All 35 patients were followed up after 6 months to 24 months.@*RESULT@#The parotid fasciae of 26 out of 35 were remained completely and none of these 26 patients developed Frey's syndrome. The parotid fasciae of 9 out of 35 were excised partly and Frey's syndrome occurred in 2 of these 9 patients. There was significant difference of Frey's syndrome between the parotid fasciae being remained completely and the parotid fasciae being remained partly.@*CONCLUSION@#The parotid fascia could be reserved completely in parotidectomy. The complete parotid fascia could prevent Frey's syndrome in the patients after undergoing parotidectomy.
