In the cysts causing disturbing symptoms and growing towards the torus tubarius, an endoscopic endonasal or transoral approach can be performed.
These patients (aged 6-25 years) presented with swollen adenoids at different grades that came into contact with the torus tubarius or even impeded the visualization of the tube ostium with ipsilateral or bilateral symptoms like middle ear effusion, aural fullness, tinnitus, snoring, and postnasal drip.
To prevent damage, the mucosa covering the torus tubarius and the structure of the tubaric ostium should be clearly identified.
But happily for some specific details terms like torus tubarius, choana etc.
The mass had originated in the posterior wall of the nasopharynx, and it had displaced the left torus tubarius laterally, obstructing the left eustachian tube (figure, D).
Endoscopic examination revealed a round polypoid mass above the left torus tubarius (figure, C).
(1) The torus tubarius is the projecting posterior lip of the eustachian tube orifice and the mobile portion of the tubal ostium.
On fiberoscopy, we noted that the mass had extended to the right torus tubarius in the nasopharynx and to the level of the epiglottic tip on the lateral wall of the hypopharynx.
This investigation revealed the presence of a horn-like, pyramid-shaped lesion on the medial aspect of the left torus tubarius. The lesion was covered with mucosa (figure, A).
Clair forceps with mirror control to perform a superior adenoidectomy provides for a more precise excision and avoids injury to the torus tubarius. In our experience, the success of superior adenoidectomy in patients with nasal obstruction is evident, as all patients experienced relief of the obstruction.
