Otalgia of unclear cause can be related to migraine mechanisms. Our group showed a high prevalence of migraine characteristics, including headache, migraine-associated symptoms, patterns of triggerability, and response to migraine treatment. Clinical criteria for diagnosis of migraine-associated otalgia are suggested for future prospective study.
Transmastoid craniotomy repair of the superior semicircular canal dehiscence using a soft tissue graft offers numerous advantages over traditional surgical approaches and can be performed safely in the outpatient setting. The strategy is particularly useful in patients with dehiscence at the superior petrosal sinus. This article will review our strategy and discuss the advantages and disadvantages of the different surgical treatments used for patients with severe symptoms from superior canal dehiscence.
Short-term lip augmentation was achieved in all 8 patients (4 patients had multiple strands placed). This study demonstrates technical ease and early safety. Surgisis should serve as scaffolding for ingrowth of striated muscle of the lip, potentially providing long-term augmentation. This study introduces Surgisis as a novel implant for lip augmentation.
In the current study, we attempted to determine normative inner ear volumetric measurements generated from three-dimensional computed tomography (CT) images. In addition, we investigated a correlation between the axial length and the volume of the labyrinth and discussed clinical outcomes of this correlation. Amira 5.2.2 software was used to create three-dimensional isosurface images of the human labyrinth using two-dimensional CT images from 35 anatomically normal patients. With the three-dimensional labyrinths, complete dimensional analysis was performed to gain insight into both the volume and the greatest axial length of the inner ear. Paired t test and Pearson correlation were used. Our volume of the inner ear inquiry reported a mean volume of 221.5 with SD of 24.3 μL (0.228 μL for males and 0.218 μL for females). The length showed a mean of 1.713 cm with SD of 0.064 cm (1.753 cm for males and 1.695 cm for females). The length was used to estimate the volume, and the estimates were within 10% of the measured volume 74.3% of the time. Normative volumetric measurements of the inner ear can be obtained by using three-dimensional CT Imaging by Amira 5.2.2 software. There was a statistically significant positive correlation between the axial length of the labyrinth and the volume of the labyrinth. The axial length of the labyrinth could be used to estimate the volume of the labyrinth, which may be clinically important to estimate the concentration of the drug distributed in the inner ear.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
