A new classification of extensions of the sphenoid sinus of Chinese adult by CT / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To examine various pneumatized extensions of the sphenoid sinus of Chinese people.@*METHOD@#The sphenoid sinus and its surrounding structures were examined from 100 computed tomography images of the sinus. The type of the sphenoid sinus was classified according to the various extensions of the sinus.@*RESULT@#The type of the sphenoid sinus was classified into the following 6 basic types based on the direction of pneumatization: sphenoid body, lateral, clival, lesser wing, anterior, and combined.@*CONCLUSION@#The variations in the extensions of pneumatization of the sphenoid sinus may facilitate entry into areas bordering the sphenoid sinus.

The necessity of post-maneuver postural restriction in treating benign paroxysmal positional vertigo / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To evaluate the necessity of postural restrictions after repositioning maneuvers in posterior canal benign paroxysmal positional vertigo (BPPV).@*METHOD@#Sixty-eight consecutive patients diagnosed of posterior canal BPPV with a positive Dix-Hallpike test. Thirty-two patients were instructed to follow postural restrictions after repositioning maneuvers, and 36 patients did not receive any postural restriction after treatment. All the patients were reevaluated at 1 week and 3 months later respectively.@*RESULT@#There was no statistical difference in number of maneuvers needed to resolve symptoms between two groups.@*CONCLUSION@#Epley maneuver is effective to treat patients with posterior canal BPPV, and postural restrictions does not improved the efficacy. Above all, we do not recommend any postural restrictions to patients with posterior canal BPPV.
