A CT study was made of the eustachian tube in normal subjects as a control group and patients with chronic pathological inflammation of the middle ear. CT made it possible to perform contiguous scans at homologous depths of 1.5 mm, showing the whole interior of the tube in clear detail: the protympanum, the bony and cartilaginous portions, and the nasopharyngeal orifice. In most of the cases of pathological middle ear inflammations, the eustachian tube lumen was seen to be constricted and obstructed with isodense matter. Our present results also show the importance of extending CT investigations beyond the tympanic cavity and the mastoid to the eustachian tube in order to have more clinical data on its condition.

Objective: This study aims to explore the clinical effects of simultaneous balloon eustachian tuboplasty (BET) in treating chronic secretory otitis media (COME) in children with bilateral tonsil and adenoid hypertrophy (TAH), providing a theoretical basis for the clinical application of BET.
Methods: From January 2023 to January 2024, 30 children diagnosed with COME and bilateral TAH were included in this retrospective study at our hospital. The cohort comprised a total of 55 affected ears.

In recent years, transcanal endoscopic ear surgery (TEES) has gained widespread recognition as an excellent surgical field for blind spots such as the sinus tympani (ST) when compared to microscopic ear surgery (MES). To investigate the postoperative hearing results for pars tensa cholesteatoma and the indications for utilizing endoscopy. The medical records of 16 patients (10 men and 6 women) with pars tensa cholesteatoma, who received initial surgical treatment between 2018 and 2022, were reviewed.

: Recurrent chronic otitis media (rCOM) is a major cause of hearing impairment, often linked to Eustachian tube (ET) dysfunction. Anatomical abnormalities, such as ET narrowing and obstructions, and functional impairments, including poor pressure regulation, play significant roles in rCOM recurrence. This study aimed to (1) identify anatomical variations of the ET in patients with rCOM using high-resolution imaging; (2) evaluate ET functional status using tympanometry, tubomanometry, and ET function tests; and (3) assess the correlation between anatomical variations and functional impairments in predicting rCOM recurrence.

We present a case of a perilymphatic fistula (PLF) caused by Eustachian tube air inflation (ETAI) that was diagnosed using cochlin-tomoprotein (CTP) testing and successfully treated using transcanal endoscopic ear surgery to seal the inner ear window. A 77-year-old woman developed hearing loss and dizziness after undergoing ETAI at a local ear, nose, and throat clinic. Despite initial bed rest and steroid pulse therapy, the hearing did not improve, and transcanal endoscopic ear surgery was performed to repair the PLF.
