摘要

Aim

To evaluate the clinical effectiveness, patient acceptance, operator feasibility, and safety of maxillary nerve block through the greater palatine canal for extensive maxillary surgical procedures.

Methods

This prospective observational study included 45 adults undergoing extensive maxillary surgery. Dental anxiety was assessed using the Modified Dental Anxiety Scale (MDAS). Standardized questionnaires evaluated anxiety, pain perception, and acceptance of the technique. Clinical outcomes included anaesthetic success, onset time, need for supplemental anaesthesia, procedural characteristics, and postoperative complications. Operator feasibility was also assessed. Statistical analyses included independent samples t-test, one-way ANOVA, and Chi-square/Fisher’s exact tests (p < 0.05).

Results

Mean needle penetration depth was 28.28 ± 1.44 mm. Successful anaesthesia without supplemental local anaesthetic was achieved in 43 of 45 patients (95.6%). Mean onset time was 2 min 16 s ± 12.1 s. Most participants demonstrated moderate-to-high dental anxiety, and 77.8% preferred a technique that avoided multiple injections. The operator reported no major technical difficulties. Transient postoperative complications, including mandibular lip and tongue numbness, blurred vision, and diplopia, occurred in a subset of patients and resolved spontaneously without permanent sequelae.

Conclusion

Maxillary nerve block through the greater palatine canal demonstrated high anaesthetic success, favourable patient acceptance, and acceptable safety. It may be useful when broad regional anaesthesia or fewer injections are desired. Further controlled studies are required to confirm its comparative effectiveness, safety, and clinical indications.
