[Clinical analysis of different canalith repositioning maneuver in treatment of apogeotropic nystagmus of horizontal semicircular canal benign paroxysmal positional vertigo].

Objective: To analyze the clinical effect of different canalith repositioning maneuver in the treatment of the apogeotropic nystagmus of horizontal semicircular canal benign paroxysmal positional vertigo (apogeotropic HSC-BPPV).

Method: Forty patients of apogeotropic HSC-BPPV colleted from March 2014 to May 2015 were divided into two groups, each group had 20 cases. The control group was repositioned with the Gufoni maneuver before the Barbecue maneuver, the research group with the improved Nuti maneuver.

[Round window catheter placement with dexamethasone perfusion for intractable sudden sensorineural hearing loss].

Objective: To investigate the efficacy of round window catheter placement with dexamethasone perfusion for 13 patients with intractable sudden sensorineural hearing loss (SSNHL).

Method: Dexamethasone (2.5 mg) was perfused transtympanically through round window catheter by Micro-infusion pump.

[Intratympanic dexamethasone for sudden sensorineural hearing loss].

Objective: To report the effect of intratympanic dexamethasone (ITD) on sudden sensorineural hearing loss (SSNHL).

Method: The effect of ITD on a case with bilateral SSNHL was presented and the relevant literature was reviewed.

Result: The patient's hearing was improved more than 40 dB in both ears.
