The transmastoid approach for resurfacing superior semicircular canal dehiscence is a safe and less-invasive technique than the standard middle fossa approach, which has many potential complications and requires much longer hospitalization. In our study, the surgeries were completed within 90 minutes, and patients stayed in the hospital only overnight.

Surgery is the mainstay of treatment for low-stage (stage I/II, ie, T1N0/T2N0) squamous cell carcinoma of oral cavity. However, a significant percentage of low-stage squamous cell carcinoma of oral cavity will develop local recurrence and disease-related mortality. In this study, we stratified 64 patients with low-stage of oral tongue and floor of mouth patients into high-, intermediate- and low-risk categories based on existing histologic risk model. The classification of these risk categories was based on presence or absence of perineural invasion and evaluation of tumor-host junction for worst pattern of invasion and lymphocytic host response. We correlated risk category and other variables with recurrence and death. In a univariate model, high-risk category tumors had a significantly higher rate of recurrence and death due to recurrence compared with low/intermediate-risk categories (P=0.000 and P=0.047, respectively). Controlling for margin status and T-stage, high-risk category had a 12.4 odds ratio of later recurrence when compared with low/intermediate-risk categories, with a P-value of 0.001. In conclusion, we found low-stage oral cavity squamous cell carcinoma patients with high-risk category have a significantly higher risk for recurrence when compared with patients in the low- or intermediate-risk category, even when controlling for margin status and T-stage. These patients may be suitable candidates for adjuvant treatment to decrease morbidity and mortality associated with a recurrence. Our results indicate that the histologic risk model is a useful and simple tool to assess risk of recurrence in stage I or II squamous cell carcinoma of oral cavity.

ObjectivesOtoplasty is a commonly performed surgical procedure that restores the ideal position of the pinna. Although the pinna is a well-recognized component of the auditory apparatus, no studies have assessed the audiological effects of this procedure. We sought to quantify the impact of pinna repositioning on speech intelligibility and reception.MethodsEighteen adults with normal hearing and pinnae were recruited and the pinna positions were randomized in each participant. Intracanal acoustical analysis was performed to calculate the Speech Intelligibility Index (SII). Hearing In Noise Test (HINT) with two azimuth speaker arrangement was also performed. The outcome measures were compared using paired t-tests for both pinna positions.ResultsThe SII significantly improved with the pinna in forward position (49.3 vs. 45.8, p<0.001). HINT thresholds also improved with the pinna forward (-6.43dB vs. -5.08dB, p=0.0003).ConclusionsPinna position affects audiological performance, in both speech intelligibility and speech reception in noise. These are novel findings that may impact the informed consent process and decision to treat for patients undergoing otoplasty.

Surveys were completed by 90 patients (58.8 per cent), of whom 72 reported having a partner. Partners reported a significant improvement in hearing (p ≤ 0.0001). Partners reported improvement in 87.0 per cent of functional scenarios, no change in 12.6 per cent, and a decline in 0.4 per cent. These findings demonstrate a significant improvement in the emotional and social effects of hearing impairment, as perceived by bone-anchored hearing aid recipients' partners.

The subjective impressions of hearing aid recipients with regards to speech reception and the spatial qualities of hearing correlate well with pre-operative audiometric results. However, the overall magnitude of sound-field improvement predicts an improvement of spatial perception, but not other aspects of hearing, resulting in hearing aid recipients having strongly disparate subjective impressions when compared to those of their partners.
