Comparison of Two Methods of Transnasal Sphenopalatine Ganglion Block

The transnasal sphenopalatine ganglion block(SPGB) is administered to patients with facial or head and neck pain. In the transnasal approach, the drip and topical methods are frequently used. We compared facial temperatures and VAS after transnasal SPGB.

About this study

The objective of this study was to compare facial temperatures and visual analogue scale (VAS) between drip method and topical method of transnasal sphenopalatine ganglion block (SPGB).

The transnasal SPGB is administered to patients with facial or head and neck pain. In the transnasal approach, the drip and topical methods are frequently used. We compared facial temperatures and VAS after transnasal SPGB.

Medical records of 74 patients who visited the pain clinic and underwent transnasal SPGB were retrospectively reviewed. A total of 156 transnasal SPGB were performed. The patients were divided into the drip-method and topical-method groups. Facial temperatures were measured in six areas of the right and left forehead, maxilla, and mandible before and 30 min after completion of the transnasal SPGB. Temperatures were compared before and 30 min after SPGB in each group and between the two groups. VAS scores were compared at same times of SPGB in each group and between the two groups.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

(1) age over 20 years ; (2) head and neck pain; (3) pain score > 4 on the VAS in the head and neck; and (4) having undergone a transnasal SPGB and having had facial temperatures measured.

Exclusion criteria

Treatment and study plan

Transnasal Sphenopalatine Ganglion Block

Procedure

In transnasal approach, several authors described the traditional technique using sterile 10cm cotton tipped applicators that are dipped in the chosen anesthetic and then advanced along the superior border of the middle turbinate, until it reaches the posterior wall of the nasopharynx. Some other techniques had described dripping one or two ml of the anesthetics into the nostril.
