Summary
Sialolithiasis, or salivary stones, was the most frequent reason for submandibular gland excision over a 20-year period. Inflammatory conditions and tumors also commonly indicated surgery, with a lower malignancy rate than previously reported.
Area of Science:
- Otolaryngology
- Head and Neck Surgery
- Pathology
Background:
- Submandibular gland pathologies necessitate surgical excision, encompassing inflammatory conditions, sialolithiasis, and tumors.
- Understanding the spectrum of indications is crucial for surgical planning and patient management.
Purpose of the Study:
- To provide a comprehensive overview of the indications for submandibular gland excision.
- To analyze epidemiological data, treatment strategies, and outcomes, including Tumor Lymph nodes Metastasis (TNM) classification and recurrence rates.
Main Methods:
- Retrospective analysis of 359 submandibular gland excisions performed over a 20-year period.
- Exclusion of procedures where submandibular gland removal was secondary (e.g., Level Ib neck dissection).
Main Results:
- Sialolithiasis was the most common indication (n=129), particularly intraparenchymal stones.
- Inflammatory causes (n=115), primarily chronic sialadenitis, were the second most frequent indication.
- Tumors accounted for 115 cases (88 benign, 27 malignant), with malignancies including lymphomas and primary salivary gland cancers.
Conclusions:
- This study offers a representative overview of submandibular gland excision indications in a large patient cohort.
- Sialolithiasis is the predominant cause for submandibular gland excision.
- The observed malignancy rate was lower compared to existing literature findings.
