Abstract Objectives: There is no study in the literature that patients with clinically-proven PET were evaluated by Valsalva CT. We aimed to evaluate the merit of Valsalva computed tomography (CT) in patients who had clinically-proven patulous Eustachian tube (PET). Design: Case-series Setting and participants: We recruited patients with clinically-proven PET. Participants: Main outcome measures: All participants underwent temporal bone CTs while they were performing the Valsalva maneuver in the supine position. Standard axial plane CT images, along with multiplanar reconstruction and 3D Air volume rendering, were used to visualize the ET in its entirety. Results: Three patients (2 females, one male) with a total of 6 ears were included in the study. All patients had suggestive symptoms of PET, including aural fullness, aerophony, and autophony and underwent clinical examination and audiologic tests. In all ears, the whole Eustachian tube could be visualized with Valsalva CT. Conclusion: For the first time, we demonstrated the merit of Valsalva CT in visualization of the Eustachian tube in its entirety in patients with clinically diagnosed PET.

Patulous Eustachian Tube

AbstractBackgroundPatulous Eustachian tube is a benign but notoriously difficult condition to treat successfully. Symptoms include autophony of voice and breathing, and aural fullness.MethodsThis paper presents a series of 8 patients (12 ears) for whom a novel computed tomography guided injection of silicone elastomer suspension implant (Vox) was used to treat patulous Eustachian tube. This is the largest and only series in the current literature using this technique.ResultsThe combined complete and partial symptom resolution rate was 91 per cent. Complications related to the procedure are described. The pros and cons of this novel approach are also discussed in relation to traditional endoscopic transnasal techniques.ConclusionComputed tomography guided injection of Vox for the treatment of patulous Eustachian tube is suggested to be a feasible alternative to endoscopic transnasal approaches, particularly for refractory cases.

Patulous Eustachian Tube

Objective To present a new classification system for reporting results and severity of disease state preoperatively of Eustachian tube (ET) obstructive (ETOD) and non-obstructive dysfunction (ETNOD) based in numerical scores, and to report the results obtained in 40 patients intervened by the author following this criteria. Methods A retrospective review of 25 patients was carried out. 20 patients presented obstructive and 5 patients presented non-obstructive (patulous) Eustachian tube dysfunction. These patients were diagnosed and treated between May 2002 and Dec 2007. Patients with ETNOD received laser endoscopic tuboplasty (LEPT) and in patients with ETOD, a cartilage grafting reconstruction of the antero-lateral wall of the ET (ETR) was carried out endonasally. Results Scores from patients were tabulated accordingly. 18 patients (90%) were symptom free, 1 patient (5%) had partial recurrence of symptoms and 1 patient (5%) had a full recurrence of symptoms at the end of the study in the obstructive dysfunction patients. 3 patients (60%) were symptom free, 2 patients (40%) had partial recurrence of symptoms after Eustachian tube reconstruction. Endoscopy, computed tomography, and audiologic results revealed the efficacy or failure of the interventions. Conclusions 1) This suggested system could serve as a starting point for Eustachian tube surgeons to develop criteria. It could be adopted if eventually accepted in the field. 2) Results obtained indicate that LEPT is effective in relieving symptoms in selected patients. 3) EPTR for patulous disease may be not effective in some cases. New experiences are further needed.

Patulous Eustachian Tube

Objective: Patulous Eustachian tube (PET) is a clinical condition that is associated with troublesome aural symptoms and is difficult to be treated successfully. The purpose of this review is to examine the published literature regarding the therapeutic value of the current treatment options for PET. Methods: We searched Web of Science, PubMed and Medline from 1999 to 2019. The search focused on papers concerning the clinical evaluation of treatment methods in PET patients. Statistical techniques were not used. Results: Prospective and retrospective case series were the types of trials available for review. We included 28 articles that evaluated the efficacy of various conservative and surgical therapeutic options. The recovery rates ranged from 50% to 100%. In most studies the assessment of efficacy was based on the subjective improvement of patient symptoms as there is no validated outcome tool available. No severe adverse events were observed in any study. Conclusion: On the basis of the available literature, it seems that conservative treatments can be considered as a primary therapeutic option for PET. Concerning the surgical interventions they seem to be a safe and valuable solution in patients with refractory disease. Finally, given the low level of evidence, prospective case–control studies with long follow-up and robust setting looking into the therapeutic approach of PET are required. The need for establishment of standard criteria of PET recovery should be underlined.

AbstractObjective:We report a novel, computed tomography guided treatment for autophony associated with a patulous eustachian tube.Methods:Case report and literature review of the management of patulous eustachian tube.Results:A 36-year-old woman presented with disabling autophony. Otoscopic examination revealed a poorly mobile right tympanic membrane. High resolution temporal bone computed tomography excluded superior semicircular canal dehiscence. The patient was diagnosed with patulous eustachian tube but failed to achieve therapeutic benefit from conventional endoscopic placement of a silicone elastomer suspension implant adjacent to the eustachian tube. Subsequently, she underwent further silicone elastomer suspension implant placement via a trans-cutaneous, computed tomography guided approach. The patient achieved prompt symptomatic relief and remained symptom-free at six-month follow up.Conclusion:This is the first published description of treatment of patulous eustachian tube using a computed tomography guided, trans-cutaneous approach. It serves to highlight to otolaryngologists the fact that computed tomography guided treatment of patulous eustachian tube may control disabling symptoms in patients who have failed to respond to convention endoscopic management.

Objective The present study was aimed at describing a case series where a preoperative diagnosis of intestinal complications secondary to accidentally ingested dietary foreign bodies was made by multidetector-row computed tomography (MDCT), with emphasis on complementary findings yielded by volume rendering techniques (VRT) and curved multiplanar reconstructions (MPR). Materials and Methods The authors retrospectively assessed five patients with surgically confirmed intestinal complications (perforation and /or obstruction) secondary to unsuspected ingested dietary foreign bodies, consecutively assisted in their institution between 2010 and 2012. Demographic, clinical, laboratory and radiological data were analyzed. VRT and curved MPR were subsequently performed. Results Preoperative diagnosis of intestinal complications was originally performed in all cases. In one case the presence of a foreign body was not initially identified as the causal factor, and the use of complementary techniques facilitated its retrospective identification. In all cases these tools allowed a better depiction of the entire foreign bodies on a single image section, contributing to the assessment of their morphology. Conclusion Although the use of complementary techniques has not had a direct impact on diagnostic performance in most cases of this series, they may provide a better depiction of foreign bodies' morphology on a single image section.

Abstract Objective Application of extended computed tomography scale (ECTS) reconstruction to diagnose metal implant failure has been described in a single case report. The purpose of this study was to compare the features and visibility of humeral transcondylar screw fractures in standard CT scale (SCTS) and ECTS images. Study Design Case series: CT images of dogs with fractured transcondylar screws were retrospectively reviewed and described in both SCTS and ECTS images. Results Five dogs with a total of six transcondylar screw failures (five right and one bilateral) were reviewed. All cases had an ongoing humeral intercondylar fissure with varying degrees of stress remodelling. The fracture was seen in all screws on ECTS images, however only in three implants on SCTS images. The measured fracture gap was larger in ECTS images in all cases (range: + 0.14 mm to + 0.28mm). The three smallest fracture gaps were not seen on SCTS images. A subtle hypoattenuating streak (artefact) was visible adjacent to the screw fracture in 5/6 of cases using SCTS images. All screw fractures occurred parallel and often slightly medial to the humeral intercondylar fissure. Conclusion Implant failure is only seen with larger fracture gaps in SCTS images, with 3/6 screw fractures not visible in SCTS compared with ECTS. A hypoattenuating streak extending perpendicular to the implant in SCTS images is suggestive of screw fracture even if this is not directly visible.

Patulous Eustachian Tube

Objectives: To review the diagnosis of patulous Eustachian tube (PET) based on the diagnostic criteria for the PET proposed by Japan Otological Society (JOS). Methods: We reviewed typical aural symptoms of PET, Eustachian tube (ET) obstruction procedure to confirm diagnosis of PET, objective findings of a patent ET obtainable from observation of the movement of the tympanic membrane, and by ET function tests (tubo-tympano-aerodynamic graphy, sonotubometry). In addition, usefulness of other tests such as patulous Eustachian tube handicap inventory-10 (PHI-10), sonotubometry with postural change (Ohta method), and sitting computed tomography (CT) to diagnose PET is described. Results and Conclusions: We have described the diagnosis of PET based on the diagnostic criteria for PET proposed by JOS; PHI-10, Ohta method, and sitting CT are also useful for the diagnosis of PET. Further investigation is needed for an accurate diagnosis and precise evaluation of the pathophysiology of this challenging disease.

Balloon Eustachian Tuboplasty

Background and Aim: Balloon eustachian tub­oplasty (BET) is a recently developed and app­roved method for management of chronic eus­tachian tube dysfunction (ETD). In the present study we aimed to evaluate the safety and effi­cacy of this method in Iranian samples. Methods: In this prospective case-series study, we included 15 adult patients with chronic ETD who were resistant to previous medical manage­ments and/or ventilation tube use. All patients underwent baseline audiometry (pure tone audio­metry and tympanometry), Valsalva maneuver, EDT questionnaire-7 (ETDQ-7), and physical examination. Three to six months after the BET procedure, all patients underwent four evaluation methods again. Results: We found a significant improvement in the mean ETDQ-7 scores comparing pre- and post-test scores (p < 0.0001). There was also a statistically significant decrease in the average air-bone gap from 40.55 at baseline to 27.22 after treatment (p < 0.001). In the Valsalva test, 17 out of 18 study ears (92.3%) had a positive result after the surgery. Under tympanographic evalu­ation, 9 ears (50%) reported a conversion from type B to type A after treatment, 2 ears (11%) had a conversion from type B to C, and 7 ears (39%) showed no any change and stayed in type B after BET. Conclusion: As a novel method in Iran, BET can be an alternative safe treatment option for chro­nic ETD. Keywords: Balloon eustachian tuboplasty; eustachian tube dysfunction; Iranian
