[The clinical characters and acoustic rhinometry analyses of 98 cases fugal ball sinusitis].

OBJECTIVE

To improve the cognition of fungal ball sinusitis (FB) for diagnosing and treatting it rightly, we retrospectively analyzed the hospitalization cases.

METHOD

We analyzed 98 cases FB patients' first symptom, acoustic rhinometry, CT manifestation, operation fashion.

RESULT

The first symptoms of FB include: 47.2% nosebleed, 38.8% snuffle, 28.6% headache and face-ache, 4.0% nasal peculiar smell, 2.0% excessive tear, 4.0% no symptom. Anterior nasoscope inspection include: 43.9% no significant abnormity, 13.3% nasoseptal deviation. 41.8% nasal cavity neoplasm (nasal polyp, nasoturbinal polyp, nasal meatus fugal ball etc), 25.5% secretion in nasal cavity. The parameters that conclude the nasal airway resistance (NAR), nasal cavity volume (NCV) and nasal minimal cross-section area (NMCA) have extremely difference (P<0.01) between FB and normal volunteers (NV): the NAR increase, but NCV and NMCA decrease; the Distance of the Minimal cross-sectional area from the nostril (DCAN) appear moving backword compared with NV. The CT manifestation: almost unilateral lesions, involved paranasal sinuses present asymmetric or symmetrical opacification: 60.2% with calcified area, 25.5% with local bone erosion, 74.5% with sinus wall sclerosis. 65.3% of the CT diagnoses as FB are accord with pathology diagnoses. The incidence of FB involve maxillary sinus most (54.1%), then sphenoid sinus (11.2%) and ethmoid sinus (5.1%), frontal sinus (2.0%), multi-sinus (32.7%). All cases operated functional endoscopy surgery: 13 cases with nasoseptal diorthosis, 4 cases with inferior meatus opening, 2 case with canine fossa opening; we clean up the fungal pathogen with different degree endoscope through different path.

CONCLUSION

The clinical symptom of FB is not representative; the acoustic rhinometry show that NAR increasing but NCV and NMCA decreasing maybe the reason of fungal infection; the CT examine is helpful for FB diagnosis; the functional endoscopy surgery is efficient therapy for FB.
