Abstract: A method for sinus surgery includes piercing first and second access openings into the anatomy of a human subject to access an inaccessible sinus site for cooperatively manipulating respective first and second surgical instruments inserted through the openings. One instrument, for example an endoscope, can permit viewing of the sinus site while the other instrument is manipulated to effect a treatment at the sinus site. The maxillary and other sinuses can be accessed and anti-inflammatory and other treatments can be applied. Systems and instruments for performing such sinus surgery methods are also disclosed.

Abstract: Method for treating chronic rhinosinusitis in a human patient. In the method a photosensitizing agent such as indocyanine green can be applied to color a nasal or sinal treatment site harboring infectious microorganisms. The photosensitizing agent can have an energy absorption peak in a near infrared wavelength region of the electromagnetic spectrum. The method can also include applying light energy from a laser source at a near infrared wavelength or wavelengths to the colored treatment site, for a duration sufficient to control the microorganisms. Apparatus for performing the method is also disclosed.

The photosensitizing agent can have an energy absorption peak in a near infrared wavelength region of the electromagnetic spectrum. The method can also include applying light energy from a laser source at a near infrared red wavelength or wavelengths to the colored treatment site, for a duration sufficient to control the microorganisms. Apparatus for performing the method is also disclosed.
