Balloon Dilation Eustachian Tuboplasty Combined with Tympanotomy Tube Insertion for Treatment of Refractory Otitis Media with Effusion: A Randomized, Prospective, Controlled Trial Comparing Local Anesthesia Combined Sedation Versus General Anesthesia.

BACKGROUND Balloon dilation eustachian tuboplasty (BET) is used to treat eustachian dysfunction but its therapeutic effect and cost-effectiveness when combined with tympanotomy tube insertion (TBI) on refractory otitis media with effusion under local anesthesia with sedation compared to traditional general anesthesia are not well understood. MATERIAL AND METHODS Forty patients with refractory secretory otitis media who received BET+TBI were enrolled in this study and randomized into the local anesthesia with sedation group (n=20) and general anesthesia group (n=20). Tympanometry (TMM), 7-item eustachian tube dysfunction questionnaire (ETDQ-7) results, intraoperative anesthesia accidents, and operation costs were compared between the groups. RESULTS Patients in the local anesthesia with sedation group exhibited intraoperative awareness and pain. Differences in TMM, ETDQ-7 results, and postoperative VAS scores between the groups were comparable (P>0.05). Notably, operative time and treatment costs in the local anesthesia group were lower compared with general anesthesia group. CONCLUSIONS The treatment effects and safety of local anesthesia and general anesthesia under BET combined with TBI for treatment of refractory otitis media with effusion are comparable. However, further studies should aim at reducing pain and discomfort.

In-Office Balloon Dilation of the Eustachian Tube under Local Anesthesia.

Balloon dilation of the Eustachian tube (BDET) is an effective treatment of Eustachian tube dysfunction. This procedure can be performed under local anesthesia in the office. This article outlines the evolution of BDET under local anesthesia, describes the techniques of in-office BDET and provides an algorithm to identify suitable patients for this procedure.

Balloon Eustachian tuboplasty under local anesthesia: Is it feasible?

OBJECTIVE: To study whether balloon Eustachian tuboplasty (BET) is a feasible and safe procedure under local anesthesia. STUDY DESIGN: Prospective multicenter case-control study. METHODS: Patients undergoing either BET (n = 13) or endoscopic sinus surgery (ESS) (n = 12) under local anesthesia, with the possibility of sedation and analgesia, were monitored during the procedure and recovery period for possible adverse effects. After the procedure, the patients responded to a questionnaire assessing their experience. RESULTS: No adverse effects were detected in the BET group. Patients in the BET group reported similar Visual Analog Scale scores for pain during the operation as the ESS group (5.0 ± 0.7 vs. 3.2 ± 0.7, mean ± standard error of the mean). However, patients in the BET group experienced more discomfort (4.2 ± 0.6 vs. 2.5 ± 0.3, respectively, P = 0.049). Seventy-seven and 92% of the patients in the BET and ESS groups, respectively, considered the anesthesia and pain relief to be sufficient. Patients from both the BET and ESS groups were almost devoid of pain 1 to 2 hours postoperatively (0.8 ± 0.2 and 1.4 ± 0.3, respectively). In total, 12 of 13 patients in the BET group, and all 12 patients in the ESS group, would choose local anesthesia with sedation and analgesia if they needed to undergo the same procedure again. CONCLUSION: BET is a safe and feasible procedure under monitored anesthesia care, including local anesthesia along with sedation and analgesia. There is need for further methodological improvement to reduce pain and discomfort during the operation. LEVEL OF EVIDENCE: 4. Laryngoscope, 127:1021-1025, 2017.

Trans-tympanic catheter insertion for treatment of patulous eustachian tube.

OBJECTIVES: To evaluate the safety and therapeutic efficacy of trans-tympanic catheter insertion (TCI) in patients with refractory patulous eustachian tube (PET). METHODS: TCI was attempted in thirty-six ears of twenty-nine patients with chronic PET refractory to conservative treatment. The catheter was inserted under local anesthesia in an operating room through the bony orifice of the eustachian tube (ET) to occlude the isthmus of the tube via a myringotomy site on the tympanic membrane. Patients were evaluated postoperatively by nasal endoscopy and by interview to document symptoms. Successful treatment was defined as complete relief or significant improvement plus satisfaction with treatment. Patients had no concurrent disease and did not undergo any additional surgical procedure. RESULTS: TCI was performed in all except one ear, in which it failed because of an abnormally narrow tympanic ET orifice. Follow-up durations ranged from 6 to 37 months, with an average of 19.3 months. Successful treatment of subjective autophony was achieved in twenty-nine (82.4%) of the thirty-five ears. Ventilation tube (VT) placement was performed in the two ears because of otitis media with effusion (OME) after TCI. In one ear, the inserted catheter was finally removed due to additional unilateral mastoiditis after VT extrusion. CONCLUSION: TCI seems to be a minimally invasive and was used successfully to treat PET. The procedure had a good overall success rate and complications were rare in the long-term.

Acupressure Bead in the Eustachian Tube.

In this article, we aim to enlighten practitioners and patients involved with acupressure beads and to contribute to their safer use by reporting a unique case of insidious intrusion of an acupressure bead into the eustachian tube. A metallic object was found in the eustachian tube of a patient while conducting a magnetic resonance imaging (MRI) examination. The object was later confirmed to be an auricular acupressure bead, and was successfully removed by performing a tympanoplasty and a canal wall down mastoidectomy. The bead was assumed to have passed through an existing perforation of the tympanic membrane. According to previously published literature, tympanic membrane perforations exist in ∼1% of the population. Therefore, middle-ear foreign bodies are relatively common occurrences for otolaryngologists. However, metallic objects such as acupressure beads are especially important in the sense that they can cause severe burns during MRI. To avoid potential complications, acupressure-bead practitioners should be aware of the possibility that intrusions through the tympanic membrane could go unnoticed.

[Bilateral Eustachian tube dilation in infants: an alternative treatment for persistent middle ear functional dysfunction]. / Beidseitige Tubendilatation beim Kleinkind: Eine Therapiealternative bei persistierender Mittelohrfunktionsstörung.

Balloon dilation has become established as a novel method for managing chronic ventilatory dysfunction of the Eustachian tube. This treatment has so far not been used in children. This article presents the first case of a pediatric patient who required antibiotics for recurrent middle ear infections and was successfully treated with Eustachian tube dilation. After a single dilation the patient was almost free of symptoms. Further studies are required in order to establish this treatment in the management of children with recurrent ventilatory dysfunction of the Eustachian tube which does not respond to conventional therapy and to define existing and potential new indications for this treatment approach.

Laser Eustachian tuboplasty: efficiency evaluation in the pressure chamber.

OBJECTIVE: Laser Eustachian tuboplasty (LETP) with ablation of the epipharyngeal orifice of the Eustachian tube (ET) shows good results in clinical observation. However, to this day, there are no reports evaluating the surgical procedure with valid test methods. The purpose of this study was to test the effect of minimally invasive LETP by means of a pressure chamber ET function test. STUDY DESIGN: Prospective surgical trial. SETTING: Tertiary and university hospital. PATIENTS: Thirty patients with a history of ET dysfunction during pressure changes were examined. INTERVENTION: Minimally invasive LETP was performed with an 812-nm diode laser under local anesthesia as an outpatient procedure. MAIN OUTCOME MEASURE: The ET function was tested preoperatively and postoperatively by pressure chamber ET function test. Eustachian tube closing pressure (ETCP) was evaluated as a measure of the tissue pressure of the ET. In cases of a severely impaired ET function, a "blocked" pattern was evident, and no measurement of ETCP was possible. RESULTS: Before minimally invasive LETP, 17 patients showed a completely blocked pattern. Postoperatively, 13 patients of this group showed an improved ET function with a restored normal opening pattern (p < 0.001). The ETCP was reduced from 6.24 ± 3.46 mbar preoperatively to 4.06 ± 2.36 mbar postoperatively (p < 0.013). CONCLUSION: The results strongly indicate that the effect of minimally invasive LETP can be proven by measuring the ET function in a pressure chamber. Results must be interpreted in combination with clinical methods like Valsalva maneuver and tympanometry. Patients with ET dysfunction during pressure changes seem to benefit from the minimally invasive LETP.

Novel rat model of tympanostomy tube otorrhea.

OBJECTIVE: Tympanostomy tube otorrhea (TTO), caused by the presence of pathogenic bacteria in the middle ear, is the most common complication of TT insertion. No studies have described a reproducible animal model of TTO. We aimed to develop a rat model of TTO which, in turn, could be used to assay the levels of TNF-α and IL-1ß through the course of the infection. METHODS: The left Eustachian tubes of 55 male Sprague-Dawley albino rats were occluded with gutta-percha (ETO=Eustachian Tube Occlusion). Middle ear (ME) effusion was ascertained by weekly otomicroscopy. At 3 weeks tympanostomy tubes were placed bilaterally and the MEs were inoculated bilaterally with Streptococcus pneumoniae through the tubes. The rats were randomly assigned to one of two daily ototopical treatments: ciprofloxacin/dexamethasone (CDX) or placebo. The animals in each of the two treatment groups were further divided to receive 1, 2, 5 or 7 days of treatment. The rats were sacrificed after treatment was finished. The rates of otorrhea, positive middle ear (ME) cultures, and levels of TNF-α and IL-1ß in the ME fluid were measured. RESULTS: Left ETO followed by ME inoculation with S. pneumoniae and treatment with placebo resulted in persistent infection (100% culture-positive ME fluid at 10 days) and otorrhea (85.7%). Persistent infection of the left ear was accompanied by significantly elevated the levels of IL-1ß and TNF-α. Ears treated with CDX had lower rates of otorrhea at all time points and lower levels of IL-1ß and TNF-α. CONCLUSIONS: This study is the first to describe a reproducible animal model of acute TTO. Surgical obstruction of the ET, followed by TT placement and ME inoculation with S. pneumoniae induced persistent otorrhea and infection. Both IL-1ß and TNF-α appear to be potential markers of persistent middle ear infection. This novel model may be used in future studies of the pathogenesis and therapy of TTO.

The Fickle finger of quackery in otology: the saga of Curtis H. Muncie, Osteopath.

OBJECTIVE: Throughout history, false and outrageous cures for deafness have been abundant. Most of these false remedies were short lived and did not gain much attention. However, Curtis H. Muncie, a New York osteopathic physician, accrued vast wealth and fame over a half century career (1910-1960) with his proclaimed cure of deafness through reconstruction of the Eustachian tube with his index finger. Through creative marketing, clever manipulation of the press, and outrageous claims of efficacy, he profited handsomely from what was, no doubt, the most egregious and remunerative instance of deafness quackery in 20th century otology. DATA SOURCES: A collection of original pamphlets issued by Curtis H. Muncie between 1921 and 1960 supplemented by articles from the popular press and both osteopathic and medical journals. RESULTS: The evidence that Dr. Muncie used unscientific methods and unscrupulous business practices is overwhelming. Famously, he fraudulently claimed in 1923 and for years thereafter that he had cured a congenitally deaf Spanish Prince (Don Jaime). At the height of the depression, his magical finger earned him over half a million dollars. Even his 1942 prison sentence for tax evasion did not keep him from resuming his flimflam upon his release. CONCLUSION: The story of Curtis H. Muncie is the quintessential example of how desperate patients can be exploited by an unscrupulous practitioner whose goal is satisfying his own avarice rather than curing illness.

Effect of artificial airway on ear complications from hyperbaric oxygen.

Hyperbaric oxygen treatment is associated with an increased risk of barotrauma to the tympanic membrane and middle ear. An artificial airway may compromise normal eustachian tube function and equilibration of middle ear pressures. This retrospective study was designed to evaluate the risk of middle ear complications in 267 patients receiving hyperbaric oxygen (HBO) therapy and to compare those with and without artificial airways. Charts of all patients were reviewed for middle ear and tympanic membrane complications and myringotomy tube placement. Eighteen of the 267 patients had artificial airways. Seventeen (94%) of these 18 patients developed middle ear or tympanic membrane complications, and 11 (61%) required tympanostomy tubes for pain, hemotympanum, or serous otitis. In contrast, 114 (45.8%) of the 249 patients without airways developed ear complications, and 53 (21.3%) required tympanostomy tubes. These results suggest that patients with an artificial airway who are receiving HBO therapy are at greater risk for developing tympanic membrane and middle ear complications than nonintubated patients. Similarly, patients with artificial airways receiving HBO frequently require placement of tympanostomy tubes.
