Abstract

A method is provided that includes inserting a stylet into a greater palatine canal of a subject, the stylet including a proximal rod shaft, having a first diameter, and a distal rod shaft, having a second diameter less than the first diameter, such that a region between the proximal rod shaft and the distal rod shaft is shaped so as to define a shoulder. The stylet is advanced through the greater palatine canal until the shoulder reaches an entrance of a greater palatine foramen, thereby preventing insertion of the distal rod shaft into a sphenopalatine fossa of the subject beyond a depth of the greater palatine canal.

Claims

1. A method comprising:

inserting a stylet into a greater palatine canal of a subject, the stylet including a proximal rod shaft, having a first diameter, and a distal rod shaft, having a second diameter less than the first diameter, such that a region between the proximal rod shaft and the distal rod shaft is shaped so as to define a shoulder; and

advancing the stylet through the greater palatine canal until the shoulder reaches an entrance of a greater palatine foramen, thereby preventing insertion of the distal rod shaft into a sphenopalatine fossa of the subject beyond a depth of the greater palatine canal.

2. The method according to claim 1, wherein the distal rod shaft comprises a cutting implement, located in a vicinity of a distal tip of the shaft.

3. The method according to claim 1, wherein advancing the stylet comprising pushing the stylet using a gentle clockwise and counterclockwise rotation motion.
