Clinical analysis of submandibular triangle masses in the past 10 years

Abstract

Abstract Objectives Lack of retrospective studies on submandibular triangle masses with large Chinese sample. Methods Basic demographic informations, history, physical examination, imaging data and histopathological results of 608 patients who underwent surgery in submandibular triangle in Xiangya Hospital of Central South University from January 2009 to June 2019 were collected. Statistical analysis were performed. Differences between malignant and benign masses were assessed by univariate and multivariate analysis. Results 405 males and 203 females were included. The average age was 43.17 ± 19.6 years old (range from 1–80). Congenital masses, inflammatory masses and tumors accounted for 2.6%, 63.5%, 33.9%, respectively. Benign tumors ,borderline tumors ,malignant tumors accounted for 48.4%, 1.6%, 50.0%, respectively. Pleomorphic adenoma and lymphoma were the most common benignancy and malignancy. Metastatic tumors were mostly originated from the head and neck cancers. Univariate analysis showed that there were significantly differences in gender, age, smoking, drinking, chewing betel nut, characteristics of the masses (pain, mobility, texture), and cervical lymph nodes. Multivariate analysis showed that age, drinking and chewing betel nut were high risk factors for malignancy. Conclusion Comprehensive analysis of the clinical parameters was helpful for preopreative diagnosis of submandibular triangle masses.
