Below are some of the lectures at the EVDF.
In the past years in literature the sinoscopy (via a trephination hole, a sinusflap or smaller surgical access) is referred to be a diagnostic tool to detect diseases within the sinus systems.
We describe a technique to scope the rostral and caudal sinuses and the dorsal and ventral nasal conchae via a transnasal access.
The concept of TSE has been developed appr. 20 years ago.
We started with anatomical research concerning the anatomical borders of each structure (nasal conchae, all sinuses and both sinus systems, sinus system openings, ethmoid region, blood and nerve supply) and tried to find out which endoscopic instruments could be useful to work with (fibre endoscopes or video endoscopes and which diameter).
While we began our practical research scoping the rostral and caudal openings into both sinus systems, we also studied how to access the rostral recessus of the dorsal and ventral nasal conchae and to scope the rostral and caudal sinus system; including the evaluation pathologic processes during sinus disease (anatomical alterations, mucosal membranes:discoloration swelling,necrosis etc.).
Over the time we learned to grade the inflammation of the mucosal membranes of the sinus which finally led to the following pathogenic grading system:
1. Acute Swelling
2. Subacute/chronic active non-demarcated sinusitis
3. Chronic ac
