Barotrauma otic5/30/2023 To not recommend the most effective non-invasive means of resolving the pain while awaiting “further investigation,” is at the least, misguided, and at worst, negligent. Certainly further investigations could be done, however, an individual experiencing the pain of barotitis has the primary goal of relieving the pain. 548) The more appropriate interpretation is that the nasal balloon technique showed the highest rate of improvement in barotitis symptoms of the reviewed studies employing non-invasive measures, and can be recommended for those individuals who typically experience the adverse effects of barotitis during flights. This is a higher success rate than seen in the reviewed studies (4,5) of topical oxymetazoline (36%) or oral pseudoephedrine (68%) and only exceeded by the study (6) employing a middle ear ventilation tube (100%).Īgain referencing the nasal balloon studies: “Two studies by the same author (2,3) evaluated the effect of a nasal balloon on participant-reported otalgia during air travel and demonstrated relief of otalgia in participants using the balloon … A low level of evidence (level 3), a high risk of bias in more than two domains and a lack of placebo control in both studies mean that nasal balloon inflation cannot be recommended for the prevention of otic barotrauma without further investigation.” (p. In Table 7, the authors acknowledge that the studies of nasal balloon use for symptoms of otic barotrauma reported 76% success in improvement (2) and 80% success in relief (3) of symptoms. ![]() Otovent balloon inflated by blowing out through nostril. If an individual is experiencing barotitis as an airplane is descending, using the nasal balloon with the regular or “advanced” technique may lessen the relative negative pressure of the middle ear and the associated discomfort. This then contracts the tensor veli palatini which can aid in opening the Eustachian tube and allowing passage of the pressurized air. If an individual is unable to pass air through the Eustachian tube with this technique, the “advanced” technique is to inflate the balloon as depicted, and while keeping the balloon inflated, swallow. In doing this, air pressure will build up in the nasopharynx to typically allow air to pass through the Eustachian tube. The device is held against one nostril while occluding the other nostril and closing the mouth and exhaling via the nostril with sufficient force to inflate the balloon. This case report describes the presentation of baroparesis in a. This combination results in higher risk for otic and sinus barotraumas at. Abstract Facial nerve paralysis due to aviation barotrauma is a rare occurrence that has previously only been seen in adults. 539)įigure 1 shows the manner in which the nasal balloon (Otovent – Abigo Medical, Askim, Sweden) is used. DESCRIPTION r Barotrauma is tissue damage resulting from the direct effects of. They conclude: “There is insufficient evidence to support the efficacy of … nasal balloon inflation … for the prevention of otic barotrauma.” (p. (1) for their review of the literature regarding the prevention of otic barotrauma, while disagreeing with their conclusions. No specific treatment is described for pneumolabyrinth and patients with no significant hearing loss, or vestibular symptoms get conservative management with head elevation, absolute bed rest, and avoidance of the Valsalva manoeuvre.Īssociation with perilymphatic fistula, disabling symptoms or complete deafness require middle ear exploration and surgical sealing of the fistula 3.Ĭochlear gas is typically associated with a poor prognosis for improvement in hearing loss, compared to pneumolabyrinths confined to the vestibule 4.To the Editor: I would like to thank Ryan et al. chronic middle or inner ear inflammation such as:. ![]() postoperative complication of middle ear surgery.temporal bone trauma is by far the most common cause with:.vestibular symptoms with paroxysmal positional vertigo.Since a pneumolabyrinth is usually associated with a traumatic perilymphatic fistula, symptoms may include 2: Pneumolabyrinth is not a rare finding following temporal bone trauma and is estimated to occur in 8% of all temporal bone fractures and almost 50% of otic capsule-violating temporal bone fractures 1.
