MRI scanning is an important technique to evaluate the olfactory system, special scanning parameters could reveal the fine structures of the olfactory pathway. Olfactory cleft, olfactory bulb/tract, olfactory sulcus and olfactory center are the main targets of the scanning. Chronic rhino-sinusitis, head trauma, congenital dysplasia and neural degenerative diseases are the primary causes of the olfactory dysfunction and have particular imaging presentations respectively. Besides indicating the olfactory pathway lesions, MRI could also present the etiology and the prognosis of the olfactory disorder.

OBJECTIVE@#To improve the diagnosis and treatment of the acute attack of sphenoid and ethmoid fungal ball sinusitis based on the analysis of clinical features.@*METHOD@#Eighteen patients with sphenoid and ethmoid fungal ball sinusitis were reviewed, and the main symptoms included headache and fever during acute attack. Endoscopy, nasal CT and MRI can provide useful information for diagnosis. Endoscopic sinus surgery was performed on thirteen patients after drug therapy, while the other 5 patients chose conservative therapy.@*RESULT@#The pathological examination confirmed the fungal lesions and the 13 patients had a good recovery. The result of CT and MRI scanning had a good accordance with the intra-operative findings. One patient receiving conservative treatment had acute attack again 2.5 months later, and antibiotics and topical nasal drugs improved the symptoms.@*CONCLUSION@#Clinical presentation and radiological imaging contribute to the differential diagnosis of the acute attack of sphenoid and ethmoid fungal ball sinusitis, then the targeted therapy can be taken.

OBJECTIVE@#To report the experience with canalplasty during the operation of overlay tympanoplasty.@*METHOD@#A retrospective review was performed on 56 patients (59 ears) that underwent tympanoplasty and canalplasty (part with intact canal wall mastoidectomy). Transcanal and postauricular incisions were made, and the posterior canal skin flap was elevated and fixed with retractor, while the anterior flap was freed. A drill was used to remove the anterior and inferior bone bulges and the adjacent bone to expose the tympanic sulcus and annulus adequately, and the epithelium of tympanic membrane remnant was removed thoroughly. After the eradication of the middle ear disease, temporal fascia was used as an overlay graft and the canal skin was replaced, and the gel-foam soaked in antibiotic and Dexamethasone solution was used to compress the canal. The patients began to use ear drops 1 week after surgery, and the gelfoam in canal lasted for 4-6 weeks.@*RESULT@#Follow-up was conducted for 0.5-3.5 years respectively, all patients gained stage I incision cure, the external auditory canal was wide and tympanic membrane gained a good shape, the complications of skin flap necrosis, external canal stenosis and cholesteatoma pearl were not occurred.@*CONCLUSION@#Canalplasty was the necessary procedure in the operation of overlay tympanoplasty which could conduce to de-epithelization of the membrane, placement of fascia and prevention of the occurrence of cholesteatoma pearl.

OBJECTIVE@#To observe the olfactory bulb's morphological change after ischemic injury in rats, and explore the role of vascular factor in olfactory disorders.@*METHOD@#Forty adult SD rats (weighting 250-300 g) were used, 30 of which were treated with permanent bilateral occlusion of both common carotid arteries, and the others were served as the control. The olfactory bulbs were carefully taken out on the 1st week, 4th week, 2nd month post operation, respectively, then observed the morphological changes by light microscopy. The ultra structure of cells in olfactory bulbs were also observed by transmission electron microscope.@*RESULT@#In rats with permanent bilateral occlusion of both common carotid arteries, the vascular pattern changed and the cell number decreased in olfactory bulbs by light microscopy. In the 1st week group, the mitral cells' mitochondria injury and metamorphism were found. In the 4th week group, the microvascular paramorphia, lipofuscin in mitral cells and metamorphic nerve fibers were found by transmission electron microscope.@*CONCLUSION@#Ischemia could injure the neuron and nerve fiber. This may be one of the reasons of olfactory disorders.
