“…Since pneumolabyrinth has been linked to poor hearing thresholds, it may be responsible for the elevated postoperative PTA among patients with this complication. 14 However, our results demonstrated that patients with pneumolabyrinth had higher PTA prior to the MCF. As such, it is possible that high PTA is a risk factor, rather than a manifestation, of post-MCF pneumolabyrinth.…”

“…Conservative treatments such as antibiotics or corticosteroid have been adopted to date. 14 Our analysis suggests that patients with pneumolabyrinth were significantly more likely to report dizziness after the MCF than patients without, even after controlling for demographic and important clinical factors. Similarly, a recent study found that pneumolabyrinth after cochlear implantation was significantly associated with dizziness.…”

Objective The present study investigates risk factors and clinical outcomes of postoperative pneumolabyrinth following the middle cranial fossa approach for superior semicircular canal dehiscence repair, a complication that has not been documented previously. Study Design Retrospective cohort study. Setting Tertiary/quaternary care referral center. Methods We conducted a retrospective review of 332 middle cranial fossa procedures from 2014 to 2020 at a tertiary/quaternary care institution. Upon identifying pneumolabyrinth cases from postoperative computed tomography temporal bone scans, we conducted multivariable logistic regression analysis to explore demographic and clinical factors that were independently linked to this complication. We also compared the rates of postoperative symptoms among patients with different grades of pneumolabyrinth. Results We identified 41 (12.3%) pneumolabyrinth cases. Patients with older age, higher preoperative pure tone average, and frank dehiscence were at higher risk for pneumolabyrinth. Furthermore, patients with pneumolabyrinth reported significantly higher rates of postoperative dizziness and exhibited significantly greater pure tone average and air-bone gap postoperatively as compared with patients without pneumolabyrinth. Finally, higher-grade pneumolabyrinth was associated with increased rates of postoperative hearing loss, and grade III pneumolabyrinth was associated with higher rates of postoperative tinnitus vs grade I and II cases. Conclusion Pneumolabyrinth following the middle cranial fossa approach was associated with poor clinical outcomes, including dizziness and auditory impairment. Old age, high preoperative pure tone average, and frank dehiscence were risk factors for this complication. The highlighted parameters may be important to note when considering this approach as a treatment option and while monitoring postoperative recovery.

“…Since then, multiple cases of pneumolabyrinth have been reported in the literature and most were associated with trauma with or without temporal bone fracture 2,3 or with a prior otologic surgery. 4,5 A systematic review published in 2021 by Botti and colleagues 6 reviewed 78 articles involving pneumolabyrinth, most cases of which were associated with temporal bone fracture (31.8%), stapes surgery (18.2%), head trauma without temporal bone fracture (14.4%), penetrating trauma (15.9%), and barotrauma (11.4%). This patient presented with a spontaneous idiopathic cause of pneumolabyrinth; she had no history of traumatic head injury nor any prior otologic surgery.…”

A 51-year-old woman presented with a 24-hour history of severe dizziness that she described as "room spinning," right aural fullness, and a subjective right-sided hearing loss. She denied any medical history of vertigo, recent upper respiratory infection, head trauma, or prior otologic surgery.A physical examination revealed no abnormalities on otoscopic evaluation; however, a strongly positive right-sided Dix−Hallpike test was elicited with rotary nystagmus; a subsequent Epley maneuver was performed. The patient's symptoms subjectively worsened during the following several days. Therefore, an audiogram test (Figure 1) and computed tomography (CT) of the temporal bone were performed.

Pneumolabyrinth is characterized by the presence of air in the inner ear due to intrusion from the tympanic cavity. It is a rare complication of stapedoplasty. Currently, there is no clear algorithm for treatment of this complication. The paper reports two cases of pneumolabyrinth being the short-term and long-term postoperative complications. In the first case, the patient, who had undergone stapedoplasty in the left ear, suddenly developed rapid hearing loss and tinnitus in the left ear with dizziness three weeks after physical activity. Physical examination revealed no evidence of the tympanic membrane defect. Audiometry revealed left-sided IV degree of sensorineural hearing loss. Pneumolabyrinth was detected on the temporal bone CT scans. In the second case, vestibulocochlear symptoms developed three days after stapedoplasty in the right ear. Pure tone audiometry revealed right-sided IV degree of mixed hearing loss. CT scan of the temporal bone confirmed the diagnosis of pneumolabyrinth. In both cases the correct position of the stapedial prosthesis, "empty" vestibule and perilymphatic fistula were found during revision tympanotomy. The prosteses were removed during surgery, Dexamethasone solution was introduced into the vestibule; stapedoplasty with autocartilage on the perichondrium was performed. After surgery, vestibular symptoms disappeared, and hearing improved.
