Nasal and paranasal sinus endoscopy. A diagnostic and surgical approach to recurrent sinusitis
Abstract:
Our endoscopic concept of the diagnosis and surgical treatment of recurrent sinusitis is based on Messerklinger's finding that almost all infections of the frontal and maxillary sinuses are rhinogenic. They are secondary to infection foci in their prechambers in the anterior ethmoid, especially in the ethmoidal infundibulum and the frontal recess, spreading from there to the dependent larger sinuses. Consequently, our functional endoscopic sinus surgery is aimed at these infection foci in the ethmoid, clearing mucosal contact areas, stenotic clefts and diseased cells. Ventilation and drainage of frontal and maxillary sinuses are re-established via their natural routes. There is no need for fenestration via the inferior meatus. Disease in the larger sinuses then usually heals without the mucosa having actually been touched. In our experience, this leaves hardly any indication for external or more radical procedures. The technique of endoscopic diagnosis and surgery are described in detail.
Insights
Recurrent sinusitis is treated by identifying and clearing infection foci in the anterior ethmoid using functional endoscopic sinus surgery. This approach restores natural sinus drainage and ventilation, often healing larger sinuses without direct intervention.
Area of Science:
- Otolaryngology
- Rhinology
- Surgical Innovation
Background:
- Recurrent sinusitis often originates from infection foci in the anterior ethmoid.
- These foci spread to frontal and maxillary sinuses, causing persistent inflammation.
- Rhinogenic origins necessitate a targeted approach to the ethmoid region.
Purpose of the Study:
- To present an endoscopic surgical concept for recurrent sinusitis.
- To detail the diagnosis and treatment of ethmoid infection foci.
- To demonstrate the efficacy of functional endoscopic sinus surgery (FESS) in restoring sinus function.
Main Methods:
- Endoscopic examination to identify infection foci in the ethmoid, ethmoidal infundibulum, and frontal recess.
- Functional endoscopic sinus surgery (FESS) to clear diseased cells and stenotic areas.
- Restoration of natural sinus ventilation and drainage pathways.
Main Results:
- FESS effectively targets ethmoid infection foci, addressing the root cause of sinusitis.
- Natural sinus routes are re-established, leading to improved ventilation and drainage.
- Significant healing of frontal and maxillary sinuses observed without direct mucosal intervention in these larger sinuses.
Conclusions:
- Endoscopic sinus surgery focused on the ethmoid is highly effective for recurrent sinusitis.
- This technique minimizes the need for more radical or external surgical procedures.
- Restoring natural sinus physiology is key to successful long-term management.
