Abstract

An insertion method includes: specifying a part of a mucous membrane which lies between a nasal cavity and a maxillary sinus and which is located in a space surrounded by an inferior nasal concha, a lacrimal bone, an ethmoid bone, and a palatine bone, as an opening formation position where an opening connected to the maxillary sinus is formed; forming the opening at the opening formation position; and inserting a medical device into the maxillary sinus through the formed opening.

Claims

1. An insertion method comprising:

probing, using a probe, a part of a mucous membrane to determine an opening formation position, the part of the mucous membrane being located between a nasal cavity and a maxillary sinus, and being located in a space surrounded by an inferior nasal concha, a lacrimal bone, an ethmoid bone, and a palatine bone;

forming an opening connected to the maxillary sinus at the determined opening formation position, by using the probe; and

inserting a medical device into the maxillary sinus through the formed opening.

2. The insertion method according to claim 1, wherein the opening formation position is determined by a repulsive force from the mucous membrane.
