Precaution of 2019 novel coronavirus infection in department of oral and maxillofacial surgery.
The epidemic of the 2019 novel coronavirus (2019-nCoV) infection has presented as a critical period. Until February 23th 2020, more than 77 000 cases of 2019-nCoV infection have been confirmed in China, which has a great impact on economy and society. It has also interferred with ordinary medical practice of oral and maxillofacial surgery seriously.

Clinicopathological study of involvement of the submandibular gland in oral squamous cell carcinoma.
Our purpose was to provide a pathological basis for preservation of the submandibular glands during neck dissection for oral squamous cell carcinoma (SCC) by investigating whether intraglandular lymph nodes exist in submandibular glands, and the modes of involvement of submandibular glands in oral SCC. We studied the records of 95 patients with oral SCC (other than that in the floor of the mouth) treated at our hospital from January 2017 to June 2018. The specimens of submandibular glands discarded after neck dissection were analysed, and serially sectioned. ⋯ No intraglandular lymph nodes or micrometastases were detected. We conclude that no intraglandular lymph nodes are present in submandibular glands, which may be involved by direct extension of the primary carcinoma or metastatic cervical lymph nodes with extranodal extension. Preservation of the submandibular glands during neck dissection seems to be feasible and safe in selected patients with oral SCC.
