Abstract
Background and Objective: Glossopharyngeal nerve block (GNB) technique has been used as alternative of treatment of cancer and noncancer pain of the oral cavity. The objective of the study is to compare the two approaches (extraoral and intraoral) of GNB in patients of carcinoma of the tongue in terms of efficacy, duration, and complications. Materials and Methods: This was a prospective comparative randomized study over a period of 1 year. Fifty patients of either sex of ASA physical status and 2, between 21 and 70 years of age, suffering from carcinoma of the tongue, were selected. The patients were randomly divided into two groups. Group I received 4 mL of 0.5% bupivacaine combined with 40 mg, of triamcinolonacetonide by extraoral approach of GNB, and Group II received the same amount of drug by intraoral approach of GNB. Hemodynamic parameters, degree of pain relief using visual analog scale (VAS), number of attempts, effect on quality of life (QOL), and complication were noted during the performance of GNB. Results: Demographic profile in both groups was comparable. Rate of complication and number of attempts to complete intervention were higher in Group I, which was found to be statistically significant. However, mean VAS scores in Group I were significantly higher as compared to those in Group II during most of the study period starting from the 1st follow-up at 30 min to the 2nd month postintervention (P < 0.05). No statistically significant difference in mean QOL scores of two groups was observed for the entire study period except at 1 week when mean scores in Group I were higher as compared to those in Group II (P = 0.011). Conclusion: The intraoral approach of GNB was better with respect to pain control and improvement in QOL whereas the rate of complication and number of attempts was lower in extraoral approach of GNB
