  2. Frontal sinus trephination - Wikipedia

    en.wikipedia.org/wiki/Frontal_sinus_trephination

    This process is a method to detect the frontal sinus outflow tract. In some cases after endoscopic sinus surgery, frontal sinus trephining is indicated in order to prevent stenosis of frontal sinus infundibulum by passing down a catheter into the frontal recess. Following endoscopic frontal sinus surgery, frontal sinus trephination can be used ...

  3. Functional endoscopic sinus surgery - Wikipedia

    en.wikipedia.org/wiki/Functional_endoscopic...

    Functional endoscopic sinus surgery (FESS) is a procedure that is used to treat sinusitis and other conditions that affect the sinuses. Sinusitis is an inflammation of the sinuses that can cause symptoms such as congestion, headaches, and difficulty breathing through the nose.

  4. Balloon sinuplasty - Wikipedia

    en.wikipedia.org/wiki/Balloon_Sinuplasty

    Sinus surgery with balloons may be performed in a hospital, outpatient surgery setting or in the physician’s office under local anesthesia. The physician inserts a guide catheter through the nostril and near the sinus opening under endoscopic visualization. A flexible guide wire is then introduced into the targeted sinus to confirm access.

  5. Endoscopic endonasal surgery - Wikipedia

    en.wikipedia.org/wiki/Endoscopic_endonasal_surgery

    This picture shows important anatomy involved in endoscopic endonasal surgery. The pituitary gland sits at the top of the picture behind the sphenoid sinus. This approach is the most common and useful technique of endoscopic endonasal surgery and was first described in 1910 concurrently by Harvey Cushing and Oskar Hirsch.

  6. Frontonasal duct - Wikipedia

    en.wikipedia.org/wiki/Frontonasal_duct

    Frontal bone fractures may result in damage to the frontonasal duct, resulting in impaired drainage of the frontal sinus and consequent predisposition to intercranial spread of infection, and the development of mucocele in the frontal sinus. Frontal sinus wall fractures may require the frontonasal duct to be sealed and the epithelium of the ...

  7. Agger nasi - Wikipedia

    en.wikipedia.org/wiki/Agger_nasi

    An enlarged agger nasi cell may encroach the frontal recess area, constricting it and causing mechanical obstruction to frontal sinus drainage. The agger nasi cell may be removed during sinus surgery to open an obstructed frontal sinus drainage pathway.

  8. Nasal surgery - Wikipedia

    en.wikipedia.org/wiki/Nasal_surgery

    Nasal surgery is a specialty including the removal of nasal obstruction that cannot be achieved by medication and nasal reconstruction. Currently, it comprises four approaches, namely rhinoplasty, septoplasty, sinus surgery, and turbinoplasty, targeted at different sections of the nasal cavity in the order of their external to internal positions.

  9. Frontal sinus - Wikipedia

    en.wikipedia.org/wiki/Frontal_sinus

    The frontal sinuses are one of the four pairs of paranasal sinuses that are situated behind the brow ridges. Sinuses are mucosa -lined airspaces within the bones of the face and skull. Each opens into the anterior part of the corresponding middle nasal meatus of the nose through the frontonasal duct which traverses the anterior part of the ...
