“…Ten studies including 367 subjects investigated various diagnostic methods. 55 - 64 The various diagnostic options summarized in this review ( Table 5 ) include the 678 Hz acoustic immittance probe tone of GSI TympStar Middle Ear Analyzer (Grason-Stadler, Eden Prairie, MN, USA), patient-reported outcome measure (PROM), sonotubometry acoustic click stimulus, nasal-noise masking audiometry (NNMA), computed tomography in the sitting position, and sonotubometry.…”

“…In terms of therapeutic approaches, several medical and surgical interventions were suggested, none of which, however, proved to be consistently effective. 67 Our review highlights the lack of randomized controlled trials and the need for more interventional studies. Non-surgical interventions mainly include the intratympanic or intranasal administration of different agents.…”

Objectives: To systematically review the literature and to summarize all evidence related to the diagnosis and management of patulous eustachian tube. Methods: The present study was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Results: Overall, 59 articles were retrieved and included in the analysis. Studies investigating treatments enrolled 1279 patients collectively, with follow-up duration varying from few days and up to 2 years. Eight studies reported medical treatments with intranasal saline instillation as the most frequently studied option. Other studies reported various surgical treatments varying from simple tympanostomy to invasive procedures targeting the orifice of the ET or the anatomical features surrounding it. In addition, 10 studies including 367 subjects investigated different diagnostic methods. Conclusion: Currently, there is a wide spectrum of diagnostic and therapeutic interventions with minimal clinical efficacy, a persistent lack of systematic guidelines, and several gaps in previous research endeavours.

“…Our patient was appropriately referred to otolaryngology and diagnosed with PET. Treatment options for PET can be minimally invasive, medical, and surgical depending on the severity of symptoms [2] . Medical options and minimally invasive options include topical estrogen or insufflation with salicylic or boric acid into the ET pharyngeal orifice.…”

“…PET was first described by H. Schwartze in 1864 [1] . PET is defined as a eustachian tube remaining persistently open [2] . Common PET symptoms include autophony, aural fullness, and hearing one's own breathing (aerophony) [1] .…”

Patulous eustachian tube (PET) dysfunction is a rare complication of weight loss, which can be easily misdiagnosed. We present a case of PET dysfunction after laparoscopic sleeve gastrectomy. A 36-year-old Caucasian female with Class III morbid obesity (131 kg, BMI 46.6 kg/m 2) successfully underwent laparoscopic sleeve gastrectomy. At her postoperative follow-up appointment six months later, her weight dropped to 96 kg and she complained of severe autophony (hearing of self-generated sounds), leading to anxiety and insomnia. She was initially misdiagnosed with a sinus infection by her primary care provider and was started on antibiotics. She was subsequently seen by an otolaryngologist who diagnosed her with PET. Weight loss can be a predisposing factor for PET. Our patient did not notice onset of symptoms of PET until significant weight loss (35 kg, 59.5% EWL).
