Abstract
Objective: To evaluate the clinical outcomes and explore the application of partial sialoadenectomy for the treatment of benign tumors in the submandibular gland (SMG).
Methods: Patients with pleomorphic adenoma of the SMG who underwent surgical treatment in the Department of Oral and Maxillofacial Surgery, Peking University Shenzhen Hospital, from October 2017 to February 2021, were enrolled and assessed in the follow-up. Fifteen patients underwent partial sialoadenectomy (PS group), and 18 patients underwent total sialoadenectomy (TS group). Postoperative salivary secretion, degree of dry mouth, appearance changes of the face and neck, nerve damage, and tumor recurrence were compared between the groups. The volume of the glands on the operated and contralateral sides of the patients in the PS group, the saliva flow rate, and their correlations, were also analyzed.
Results: There was no recurrence during the follow-up period. The whole saliva flow rate at rest in the PS group was higher than that in the TS group [(2.15±1.10) g/5 min vs. (1.35±0.97) g/5 min, t=2.208, P=0.035)], while the stimulated saliva flow rate was not significantly different. The objective feeling of dry mouth, evaluated by visual analogue scale (VAS) score, was more obvious in the TS group than in the PS group (Z=-2.244, P=0.025). In the PS group, the resting saliva flow rate of the SMG on the operated side was lower than that on the contralateral side of the same patient [(0.92±0.40) g/5 min vs. (1.18±0.40) g/5 min, t=-2.821, P=0.014], however, in the cases whose remaining SMG was more than 80% of the contralateral side, the saliva flow rate of both sides was not significantly different (t=-0.027, P=0.980). There was no significant difference in the saliva flow rate per unit volume of the gland on either side (t=-0.015, P=0.989), and the saliva flow rate of the operated SMG was positively correlated with the volume of the remaining gland (r=0.750, P=0.012). The VAS scores for neck deformity were not significantly different between the two groups (t=-0.997, P=0.319). No symptoms of nerve injury occurred in either group.
Conclusion: Partial sialoadenectomy in the SMG can safely remove benign tumors while preserving glandular secretory function, with fewer complications and improved quality of life.

Beijing Da Xue Xue Bao Yi Xue Ban / Journal of Peking University (Health Sciences), established in 1959, is a national academic journal sponsored by Peking University, and its former name is Journal of Beijing Medical University. The coverage of the Journal includes basic medical sciences, clinical medicine, oral medicine, surgery, public health and epidemiology, pharmacology and pharmacy. Over the last few years, the Journal has published articles and reports covering major topics in the different special issues (e.g. research on disease genome, theory of drug withdrawal, mechanism and prevention of cardiovascular and cerebrovascular diseases, stomatology, orthopaedic, public health, urology and reproductive medicine). All the topics involve latest advances in medical sciences, hot topics in specific specialties, and prevention and treatment of major diseases.
The Journal has been indexed and abstracted by PubMed Central (PMC), MEDLINE/PubMed, EBSCO, Embase, Scopus, Chemical Abstracts (CA), Western Pacific Region Index Medicus (WPR), JSTChina, and almost all the Chinese sciences and technical index systems, including Chinese Science and Technology Paper Citation Database (CSTPCD), Chinese Science Citation Database (CSCD), China BioMedical Bibliographic Database (CBM), CMCI, Chinese Biological Abstracts, China National Academic Magazine Data-Base (CNKI), Wanfang Data (ChinaInfo), etc.
