In-office balloon sinus dilation versus medical therapy for recurrent acute rhinosinusitis: a randomized, placebo-controlled study.

BACKGROUND: A limited number of studies have demonstrated symptomatic improvement for recurrent acute rhinosinusitis (RARS) patients after endoscopic sinus surgery. In this randomized, controlled study we evaluated 24-week outcomes for balloon sinus dilation (BSD) performed in-office (IO) with medical management (MM) as compared with MM only for RARS patients. METHODS: Adults diagnosed with RARS were randomized to groups with BSD plus MM (n = 29) or MM alone (n = 30). Patients who received MM alone also received a sham BSD-IO procedure to blind them to group assignment. Patients were followed to 48 weeks posttreatment. The primary outcome was the difference between arms in change in Chronic Sinusitis Survey (CSS) score from baseline to 24 weeks. Secondary endpoints included comparisons of Rhinosinusitis Disability Index (RSDI) score, medication usage, medical care visits, and sinus infections. RESULTS: Change in patient-reported quality of life (QOL), as measured by the CSS total score from baseline to 24 weeks, was significantly greater in the BSD plus MM group compared with the MM-only group (37.3 ± 24.4 [n = 26] vs 21.8 ± 29.0 [n = 27]; p = 0.0424). CONCLUSION: BSD plus MM proved superior to MM alone in enhancing QOL for RARS patients. BSD plus MM should be considered as a viable treatment option for properly diagnosed RARS patients.

Radiographic diagnosis of trans-stapedial cerebrospinal fluid fistula.

OBJECTIVE: To report the high-resolution computed tomography and magnetic resonance imaging (MRI) findings of a bulging oval window in children with recurrent meningitis and congenital cerebrospinal fluid fistula. STUDY DESIGN: Case series. SETTING: Academic medical center children's hospital. SUBJECTS AND METHODS: A series of eight ears in four children with profound, bilateral sensorineural hearing loss and perilymphatic hydrops were evaluated. Two patients presented with recurrent meningitis. All children were assessed with high-resolution computed tomography, and two children also underwent MRI. RESULTS: Seven of eight ears had a common cavity malformation. The vestibular compartment showed severe dysplasia (n = 5), moderate dysplasia (n = 1), or a single semicircular canal (n = 2). The lamina cribrosa was clearly absent in four of eight ears. Its presence was difficult to assess in ears with small internal auditory canals. A bulging oval window, present in six of eight ears, was defined as a fluid density on high-resolution computed tomography or a hyperintense mass demonstrated by T2-weighted MRI protruding from the vestibule into the middle ear cavity. When present, this herniation of a fluid-filled sac could be seen on both MRI and computed tomography. This imaging finding was surgically confirmed in two patients. CONCLUSION: The bulging oval window, which represents a fluid-filled sac, can be identified by both high-resolution computed tomography and MRI. Communication between the middle ear and the subarachnoid space through the inner ear is an important etiology for recurrent meningitis in children with sensorineural hearing loss.
