Coblator-Assisted Partial Glossectomy with Neck Dissection in Oral Tongue Carcinoma : A Safe and Function Preserving Surgical Technique

Abstract

Background: Oral tongue squamous cell carcinoma (OTSCC) is a prevalent malignancy in India. Conventional surgical techniques, while effective, can be associated with significant morbidity. Coblation technology offers precise tissue dissection with minimal thermal damage, potentially improving functional outcomes.
Objective: To evaluate the safety, oncological adequacy, and functional outcomes of coblator-assisted partial glossectomy with neck dissection in early-stage OTSCC.
Methods: A prospective observational study was conducted on 15 patients (T1-T2, N0-N1). All underwent coblator-assisted partial glossectomy with neck dissection. Intraoperative parameters (blood loss, operative time, margin status), postoperative recovery (pain, oral intake resumption), functional outcomes (speech, swallowing), and oncological results were assessed.
Results: The mean intraoperative blood loss during glossectomy was 23.4 mL. All patients achieved clear surgical margins. Postoperative pain was low (mean VAS 3.1 on Day 1), and oral intake resumed early (mean 2.1 days). Speech and swallowing functions were well-preserved. No major complications or locoregional recurrences were observed over a 24-month follow-up.
Conclusion: Coblator-assisted partial glossectomy is a safe and effective technique for early OTSCC, offering reduced blood loss, favourable functional recovery, and sound oncological outcomes. It represents a promising function-preserving surgical alternative.
