Objective To determine if age affects radiographic incidence of superior semicircular canal dehiscence (SSCD) in pediatric patients. Study Design Retrospective case review. Setting Tertiary children’s hospital. Patients Patients (0–18 yr) with high-resolution computed tomography (CT) temporal bone scans from April 2001 to February 2013. Interventions Diagnostic high-resolution CT temporal bone scans. Main Outcome Measures Findings of dehiscent, thin, or normal SSC on CT scans (including reconstructed Poschl views). Interobserver radiographic interpretation rate between neuroradiologist and otologist. Results Seven-hundred CT scans (1,400 ears) were reviewed, and 1,188 ears were acceptable for analysis. Twenty-three ears (1.9%) had dehiscent SSC, 185 ears (15.6%) had thin SSC, and 980 ears (82.5%) had normal SSC. Median ages of dehiscent, thin, and normal canals were 5, 7, and 9 years, respectively ( p < 0.05). As age increased, the incidence of dehiscent and thin SCC cases decreased; for example, dehiscent or thin canal existed in 51.4% of children less than 12 months, 17.5% of children between 1 and 2 years, 18.5% of children between 3 and 10 years, and 10.9% of children between 11 and 18 years. The &kgr; value of agreement between neuroradiologist and otologist was 0.814, demonstrating a high value of agreement (p < 0.05). Conclusion Radiographic SSCD, although uncommon, appears to be more prevalent in younger children, especially infants younger than 12 months. This suggests that the SSC may develop more bony covering with age.

Objective To compare subjective and objective findings between patients with true dehiscence versus thin bone over the superior semicircular canal (SSC). Study design Retrospective case series. Setting Tertiary referral center. Patients All patients from our institution with true dehiscence or thin bone over the SSC on computed tomography temporal bone (oblique view) from 2007 to 2013. Main outcome measures Subjective test: Dizziness Handicap Inventory (DHI). Objective tests: Infrared video eye recording with varying stimuli (Tulio, Fistula, and Vibration); vestibular evoked myogenic potential (VEMP); electrocochleography; videonystagmography; pure-tone audiometry (i.e., air-bone gap). Results Fifty-four patients (64 ears) were reviewed. Thirty-nine patients (47 ears) had true dehiscence of the SSC on temporal bone computed tomography. Fifteen patients (17 ears) had thin bone over the SSC. There was no statistical difference in DHI scores for patients with true dehiscence versus those with thin bone over the SSC. Only cervical VEMP and air-bone gap via pure-tone audiometry revealed a significant difference between the two groups. The remaining vestibular assessments did not demonstrate any difference. No significant correlations were revealed between DHI and objective test findings across and within the two groups. Conclusion Among the objective tests, cervical VEMP and pure-tone audiometry are the only tools to distinguish between true dehiscence and thin bone over the SSC. DHI does not differentiate between these two groups. Furthermore, no correlation exists between DHI and any objective finding. Further investigation is necessary to develop a validated subjective symptom index of patients with SSC syndrome.

As cochlear implantation increases, surgeons are noting possible anatomical differences in pediatric population. Outcome objectives were to study pediatric temporal bone anatomy using high‐resolution temporal bone imaging, and analyze the anatomical differences in group 1 (<12 months) versus group 2 (1–4 years) versus group 3 (5–10 years) versus group 4 (10–18 years).

Hypothesis To determine the best method of removing hydroxyapatite cement from the temporal bone in the postoperative period. Background The advent of hydroxyapatite cement in neurotologic surgery of the temporal bone has dramatically decreased the rate of postoperative cerebrospinal fluid leaks. However, there is no literature currently available on how to manage these patients in the setting of postoperative hematomas of the cerebellopontine angle. Methods Nine cadaveric temporal bones were obtained that had previously undergone translabyrinthine approach drilling in an academic temporal bone lab. Fascia and adipose tissue were placed medial to the facial nerve and the temporal bone was then filled with hydroxyapatite cement to the level of the cortex. Removal of hydroxyapatite cement was undertaken using a Freer elevator, mastoid bone curette, and finally, a drill in sequential fashion. This occurred at 9 predetermined time intervals from 1 to 30 hours and was timed in each case. Results Removal using the freer and curette failed in each case, and the drill was ultimately used to remove the hydroxyapatite cement in all cases. The time to reach the packed fascia and adipose tissue varied from 3 to 6 minutes, average time is 4.27 ± 0.84 minutes. Conclusion Although hydroxyapatite cement has dramatically decreased the rate of postoperative cerebrospinal fluid leak in translabyrinthine surgery, its use has also brought a new set of considerations. This study suggests that hydroxyapatite cement removal in the setting of postoperative hematoma after translabyrinthine surgery would require drilling rather than bedside incisional opening alone. Like standard craniotomy approaches, postoperative hemorrhage management requires intraoperative drainage.

Objectives: Correlate the findings of preoperative magnetic resonance imaging (MRI) and computed tomography (CT) in temporal bone carcinoma with histopathological findings following lateral temporal bone resection. Methods: In this retrospective review, 11 cases of temporal bone carcinoma over the past 3 years were reviewed at our institution. Preoperative CT and MRI scans were systematically reviewed for tumor involvement in 10 anatomic areas involving and surrounding the temporal bone. These were compared with results found on final histopathology. Results: Among the 11 cases, 30 anatomic areas of tumor involvement identified on CT imaging were also found on MRI and confirmed on final histopathology. Two areas suggestive on tumor involvement on CT and MRI (parotid gland and regional lymph nodes) and 2 areas on MRI alone (mastoid antrum and middle ear) were negative on final histopathology. MRI did not change the preoperative clinical staging in any of the 11 cases, however, examination of the MRI in 1 case suggested temporal lobe involvement that was not seen on CT images and subsequently changed the management of the patient. Conclusions: The addition of MRI in the preoperative evaluation of these patients confirmed the extent of tumor involvement seen on CT and did not identify additional tumor or facial nerve involvement in most cases except for one advanced case. In this case, the addition of the MRI findings changed the treatment plan. While CT remains the imaging gold-standard for preoperative evaluation and staging, MRI should be obtained in evaluating advanced temporal bone tumors.

Objectives: (1) Examine the efficacy of quick-setting, hydrophilic formulation of hydroxyapatite cement (HAC) used in cranioplasty for the prevention of cerebrospinal fluid (CSF) leaks and long-term wound complications following translabyrinthine acoustic neuroma (TLAN) surgery. (2) Review evolution of HAC cranioplasty. Methods: Retrospective case review from 2006 to 2013 in atertiary referral center. Consecutive patients undergoing translabyrinthine approach for acoustic neuroma tumors were operated on by the senior author. Intervention: Therapeutic: Cranioplasty combining a medial abdominal fat graft with hydrophilic hydroxyapatite cement filling the mastoid. Main outcome measures: Incidence of cerebrospinal fluid (CSF) leaks and any wound complications. Results: Forty-four patients met inclusion criteria. There were no CSF leaks or other wound complications in this series. Conclusions: Hydrophilic HAC appears to be safe and efficacious for cranioplasty following translabyrinthine acoustic neuroma surgery.

Objectives: 1) Study pediatric temporal bone anatomy using high resolution temporal bone imaging. 2) Analyze the anatomical differences in infant (< 2 years old) versus toddler (2-5 years old) versus child (6-10 years old) versus preadolescent and adolescent (>10 years old) as it pertains to cochlear implantation Methods: A retrospective chart and radiologic review was done of pediatric patients at our institution undergoing high resolution computed tomography (CT) scan of the temporal bones from April 2001 to February 2013. Charts were reviewed for clinical and demographic information. Scans were reviewed by experienced surgeons, radiologists, or both to study the Cobb angle between an ideal trajectory of a cochlear implant into the basal turn of the cochlea and a realistic approach for surgical insertion. Results: Seven hundred fifty patients were identified. Seven hundred and twenty-three charts and scans (1446 ears) were reviewed, and 27 patients were eliminated due to poor scan quality. The age range was 8 days to 22 years. Fifty-six point three percent (n = 407) of patients were male. Each group of patients was evaluated. One hundred and five patients were < 2 years old, with Cobb’s angle ranging 22.3-36.4°. One hundred and forty-seven patients were 2-5 years old, with Cobb’s angle ranging 14.6-31.7°. Two hundred four patients were 6-10 years old, with Cobb’s angle ranging 7.7-22.3°. Two hundred and fifty-seven patients were >10 years old, with Cobb’s angle ranging 7.7-27.2°. Conclusions: Despite considerable variations, there is a substantial difference in the Cobb’s angle among the age groups. The largest difference is between infancy (< 2 years old) and toddler (2-5 years old). These differences are surgically relevant for round window identification and facial nerve safety during cochlear implant surgery in infants.
