● SLC26A4 mutations are the most prevalent cause of enlarged vestibular aqueduct (EVA).
● SLC26A4 mutations in a boy with EVA and his siblings were analyzed in comparison with 100 healthy controls.
● A novel heterozygous frameshift mutation p.I713LfsX8 was found in two siblings.
● The herpes virus serology had no impact on the prognosis of idiopathic sudden SNHL (ISSNHL).
● There was found no significant difference of prognosis in patients with and without HSV reactivation.
● Acyclovir therapy combined with corticosteroids had no benefit in patients with ISSNHL.
● Budesonide nasal irrigation improved the mean SNOT-22 and endoscopic score.
● The total amount of oral steroid for sinusitis control decreased.
● The use of inhaled steroid for asthma control did not decrease.
● Budesonide nasal irrigation is an effective postoperative treatment for sinusitis in asthma patients.
● Recurrent laryngeal nerve on both sides are located inferiorly to the midpoint of trachea vertical height at first tracheal cartilage level.
● Upper half of trachea vertical height at first tracheal cartilage level is safe during surgery.
● Left recurrent laryngeal nerves are significantly deeper at the first treacheal ring.
● Left recurrent laryngeal nerves located lower at the posterior half of the first tracheal ring.
● Contrast-enhanced ultrasound (CEUS) allows better identification of the vascular anatomy and lymph node perfusion.
● Hyperplastic and malignant lymph nodes show different enhancement patterns.
● CEUS have the ability of evaluating cervical lymph nodes with no morphological change.
● 18F-fluorodeoxyglucose positron emission tomography/computed tomography with contrast-enhancement (CE PET/CT) was more accurate than CT for differentiating N0, N1a, and N1b (81.2% vs. 68.2%).
● For ipsilateral level IV and IV, CE PET/CT was more sensitive and has higher negative predictive value than CT.
