BACKGROUNDBronchoplasty plus pulmonary arterioplasty has become one of the standard surgical operation for central-type lung cancer. The aim of this study is to review the surgical experience of bronchoplasty and pulmonary arterioplasty in treatment of central-type lung cancer.

METHODSFrom 1987 to 2005, 56 patients with central-type lung cancer underwent bronchoplasty and pulmonary arterioplasty. There were 45 males and 11 females with a mean age of 56 years. According to pTNM classification, 18 cases were in stage IIB, and 32 in stage IIIA and 6 in stage IIIB. Histologically, there were 35 cases of squamous cell carcinoma, 14 cases of adenocarcinoma, 4 cases of small cell lung cancer and 3 cases of carcinoid. The surgical procedures included sleeve resection of bronchus for 30 cases, wedge resection of bronchus for 26 cases, and sleeve resection of pulmonary artery for 16 cases and wedge resection of pulmonary artery for 40 cases.

RESULTSOne patient died in the perioperative period. The overall 1-, 3-, and 5-year survival rate was 79.6% (43/54), 48.1% (25/52) and 34.0% (17/50), respectively.

CONCLUSIONSThe results suggest that bronchoplasty and pulmonary arterioplasty can decrease the proportions of total pneumonectomy and exploratory thoracotomy and expand the indication of operation. Bronchoplasty and pulmonary arterioplasty can be achieved with satisfactory outcome for central-type lung cancer, especially for those patients with advanced lesions or poor pulmonary function.

Neck dissection for oral squamous-cell carcinoma (OSCC) is a clinically controversial issue and has therefore been the subject of abundant research. However, no one has performed a bibliometric study on this topic to date. The aim of this study was to assess the development of research on neck dissection for OSCC in terms of the historical evolution, current hotspots and future directions, particularly including research trends and frontiers from 2010 to 2019. Literature records related to research on neck dissection for OSCC were retrieved from the Web of Science Core Collection (WoSCC). CiteSpace was used as a tool to perform a bibliometric analysis of this topic. The survey included 2 096 papers. "Otorhinolaryngology" was the most popular research area. The most active institutions and countries were Memorial Sloan Kettering Cancer Center and the USA, respectively. Shah J.P. was the most cited author. Among the six identified "core journals", Head & Neck ranked first. The top three trending keywords were 'invasion', 'upper aerodigestive' and 'negative neck'. 'D'Cruz AK (2015)' was the most cited and the strongest burst reference in the last decade. The study evaluated the effect on survival of elective versus therapeutic neck dissection in patients with lateralized early-stage OSCC. The depth of invasion and the management of N0 OSCC were research frontiers in this field. The present study provides a comprehensive bibliometric analysis of research on neck dissection for OSCC, which will assist investigators in exploring potential research directions.

OBJECTIVES: The aim of this study was to compare the anterior and posterior occlusal plane characteristics of patients with different temporomandibular joint osseous statuses. METHODS: A total of 306 patients with initial cone beam CT (CBCT) and cephalograms were included. They were divided into three groups on the basis of their temporomandibular joint osseous status: bilateral normal (BN) group, indeterminate for osteoarthrosis (I) group, and osteoarthrosis (OA) group. The anterior and posterior occlusal planes (AOP and POP) of the different groups were compared. Then, the regression equation was established after adjusting for confounding factors, and a correlation analysis between the occlusion planes and other parameters was performed. RESULTS: SNA, SNB, FMA, SN-MP, Ar-Go, and S-Go were correlated with the occlusal planes. Relative to the BN and I groups, the FH-OP of the OA group increased by 1.67° on the average, FH-POP increased by 1.42° on the average, and FH-AOP increased by 2.05° on the average. CONCLUSIONS The occlusal planes were steeper in the patients with temporomandibular osteoarthrosis than in the patients without it, and the mandible rotated downward and backward. The height of the mandibular ramus, the mandibular body length, and the posterior face height were small. In clinical practice, attention should be given to the potential risk of temporomandibular joint osteoarthrosis in such patients. In addition, SNB, FMA, SN-MP, Ar-Go, S-Go, and occlusal planes had moderate correlations.
