“…In reports of intensely overgrown mucosa, the zone of destruction extends from the ET eustachian tube orifice into the posterior wall of the cartilaginous tubal lumen. Depending on the size of the treated region, several ablation applications are to be done until the ablated zone appears gray-white [ 20 ].…”

The Eustachian tube is a crucial pneumatic component of the head and neck region and is often neglected as an important site of insidious pathologies. In our literature review, we negotiate the management of eustachian tube dysfunction and explore the various therapeutic and surgical options available at our disposal. We begin by investigating the physiological nature of the eustachian tube and its role in the body's functioning. We also list and elaborate on the various pathologies affecting the Eustachian tube and its associated structures. The review then outlines eustachian tube dysfunction and discusses the pathophysiology involved in the genesis of the condition and its progression. Further, the review explores the tools most commonly used to diagnose or alleviate the condition, including, but not limited to, the Valsalva maneuver, Toynbee maneuver, tympanometry, pressure chamber test, and video nasopharyngoscopy. We also touch on The ETS-7 questionnaire and then on the various surgical interventions that may be used to manipulate the condition. The review also describes conventional tympanostomy and myringotomy, along with more novel techniques such as microwave ablation, laser eustachian tuboplasty, and balloon eustachian tuboplasty. We conclude by establishing the most favorable course of treatment in cases of eustachian tube dysfunction.

Objective: The objective of this study was to assess the graft and functional outcomes of inlay butterfly cartilage-perichondrium graft myringoplasty in an office setting. Material and Methods: Adult patients with chronic perforations underwent inlay butterfly cartilage-perichondrium graft myringoplasty under local and topical anesthesia. The graft and functional outcomes, intraoperative pain score, and complications were evaluated at 6 months postoperatively. Results: A total of 39 patients (39 ears) were included in this study. All patients completed 6 months of follow-up. The mean operation time was 26.5 ± 3.2 (ranged from 21 to 32) minutes. The intraoperative mean pain score was 0.61 ± 0.28. The graft success rate was 97.4% (38/39) at 6 months postoperatively. The mean preoperative air-bone gap (ABG) was 19.18 ± 4.01 dB, while the mean postoperative ABG at 6 months was 10.56 ± 2.27 dB ( P < .05; Paired-Samples T Test). The functional success rate was 100.0% (38/38). Endoscopic examination showed that the transplanted perichondrium graft gradually atrophied, flattened, and became indistinguishable from the surrounding tympanic membrane 2 to 3 months following surgery, the superficial layer of perichondrium graft formed the crust and migrated into the external auditory canal at 3 to 6 months postoperatively. Conclusions: Perichondrium-cartilage inlay butterfly myringoplasty is a highly successful and minimally invasive procedure well tolerated by adults for closure of small- and medium-sized perforations in an office setting.

Objective: This study evaluated the effects of radiofrequency ablation (RFA) eustachian tuboplasty on the treatment of chronic otitis media with effusion (COME), and associated complications, in patients with premature extrusion of the tympanostomy tube (TT). Materials and Methods: Tuboplasty and T-tube reinsertion were performed in 23 ears with COME, a history of premature TT extrusion, and thickened mucus. Tube retention, perforation closure, hearing improvement, and complications were evaluated. Results: All 23 patients with COME and previous premature TT extrusion had remarkable mucosal hypertrophic disease or mucosal polypoid changes in the posterior cushion or posterior wall in the nasopharyngeal eustachian tube (ET) orifice. All surgeries were completed within 20 minutes after general anesthesia and were performed in the operating room. Pre-and post-air-bone gap gain was 18.3 ± 2.5 dB. The TT was retained for at least 12 months in 19 patients, whereas intentional premature removal at postoperative 8 to 9 months was required in 2 patients and premature extrusion occurred in 2 patients. Thus, the tube retention success rate was 91.3% (21/23). Of the 21 ears with intentional removal, the perforation closure rate was 81.0% (17/21). None of the patients reported RFA-related serious adverse events or a patulous ET. However, a scar synechia of the anterior-posterior wall was seen in 1 ET orifice, and stenosis of the ET orifice in 4 patients. Conclusions: RFA eustachian tuboplasty combined with TT insertion is a simple and minimally invasive technique for the treatment of intractable COME in patients with a thickened mucosa of the nasopharyngeal ET orifice. This technique may prevent premature TT extrusion.
