I designed this instrument with three distinct advantages in view: 1. The measured 8.5 mm. needle is to assure safety against injury to the sphenopalatine ganglion. 2. The safety shank permits insertion only of the measured needle. 3. On connecting a loaded 1.5 cc. Yale syringe to the sphenopalatine needle before use, slipping of the needle is prevented by the 45 degree angle of the proximal end, which allows continuous free vision of the nasal area and makes it possible to hold the instrument in the proper place during the injection.
New needle for injection into the nasosphenopalatine ganglion.
The usual method of sterilization is observed. Enlarged turbinates are reduced by spraying if necessary. The area over the sphenopalatine fossa is first thoroughly anesthetized by means of a cotton-wrapped applicator moistened with a suitable local anesthetic such as 10 per cent solution of cocaine or 1 per cent solution
