JOURNAL FREE ACCESSInformation on rhinomanometry was obtained through questionnaires send to 2, 191 otorhinolaryngologist in the Japan Rhinologic Society June 1, 2000 with answers from 1, 236 within 1 month -a 56.4% response. About half have rhinomanometers in their hospital or clinic. Though many use the rhinomanometer as a clinical test, 17.0% of them did not. They mainly conducted rhinomanometry in patients with allergic rhinitis, chronic sinusitis, hypertrophic rhinitis, septal deviation, nasal polyposis, and sleep apnea. They also used it to assess nasal airway resistance in patients who reporting nasal obstruction but whose rhinoscopic findings were almost normal. Rhinomanometry was used for clinical evaluation of nasal obstruction both in surgical and in conservative treatment of nasal disease. The period between the diagnosis of nasal disease and surgical treatment was over 1 month for 81.6% of doctors. Moreover 93.5% answered that rhinomanometry must be done over 1 month after the surgery. Eighty three per cent of the doctors considered that rhinomanometry was useful in the diagnosis of nasal obstruction. These results strongly suggest that rhinomanometry is essential for otorhinolaryngologist in clinical evaluation of nasal obstruction associated with many nasal diseases.View full abstractDownload PDF (989K) -

JOURNAL FREE ACCESSA 75-year-old man developed left side ptosis and double vision. Opthalmological examination showed this to be due to disturbance of the left oculomotor nerve. The left nasal cavity was filled with a mass lesion. In computed tomography and magnetic resonance imaging, a shadow was observed in the left posterior ethmoid and sphenoid sinuses. Endoscopic sinus surgery and pathological examination revealed neurinoma. The tumor was mostly resected by a microdebritter. The postoperative course was satisfactory. The patient has recovered fully from oculomotor nerve palsy and has had no recurrence in the 21 months postoperatively.View full abstractDownload PDF (7748K) -

JOURNAL FREE ACCESSIn everyday examination, it is usual to encounter odontogenic maxillary sinusitis patients. Odontogenic maxillary sinusitis is generally best diagnosed by dental X-ray imaging. Many medical facilities not having a dental X-ray unit use coronal computed tomography (CT) images to diagnose odontogenic maxillary sinusitis. Coronal CT imaging causes artifacts, however due to dental prosthesises. Computed tomography-Multiplanar reformation (CT-MPR) imaging has proved useful in evaluating the paranasal sinus because it is not influenced by dental prosthesises. We evaluated the usefulness of CT-MPR for diagnosing odontogenic maxillary sinusitis by retrospectively analyzing 16 patients, with the following results:
1. We coudn't diagnose all cases of odontogenic maxillary sinusitis in posteroanterior and Waters projection images.
2. Panoramic radiography is needed to diagnose odontogenic maxillary sinusitis.
3. Dental X-ray imaging missed some cases, but all cases were diagnosed by CT-MPR imaging, giving a 100% diagnosestic rate.
CT-MPR imaging is thus at least as valuable or better than dental X-ray imaging in diagnosing odontogenic maxillary sinusitis.View full abstractDownload PDF (7124K) -

JOURNAL FREE ACCESSWe describe a rare case of bilateral paranasal squamous cell carcinoma. A 64-year-old man visited Toride General Hospital complaining of bilateral nasal obstruction and diplopia. He had undergone a right Caldwell-Luc procedure for a right squamous cell papilloma 14 years previously. Physical examination revealed polypoid masses in both nasal cavities. Although a CT scan showed bone destruction on both side of the skull base and in the lamina papyracea, invasion through the nasal septum and the medial wall of the ethmoids was not observed. Moreover, an MRI examination revealed cystic lesions in both frontal sinuses. The patient underwent endoscopic endonasal surgery. Microscopic examination of the tumor specimen obtained from the right nasal cavity showed a squamous cell carcinoma with inverted papilloma, while that obtained from the left nasal cavity showed a squamous cell carcinoma. Histologically, we could not determine if the bilateral carcinomas represented independent primary lesions or extensions from one side to the other.View full abstractDownload PDF (5179K) -

JOURNAL FREE ACCESSFrontal sinus cysts often occur after paranasal surgery in as many as 50% of all patients with this disease. In addition to surgery-related cysts, traumatic and primary cysts have also been reported. Fronatl sinus cysts are often discovered after the occurrence of exophthalmos and headaches. We encountered a patient with a frontal sinus cyst that had excluded the frontal lobe. The cyst was discovered because of 4-hour period of persistent amnesia. A 74-year-old male visited the Neurosurgical Department of our hospital because of a 4-hour period of amnesia that he experienced while traveling. CT scanning and MRI examination suggested a frontal sinus cyst, and he was referred to the Department of Otorhinolaryngology for admission. The frontal sinus cyst was resolved by surgery. The cyst contained a viscous fluid. Since the surgery, the patient's course has been uneventful, and no relapses of amnesia have occurred.View full abstractDownload PDF (5213K) -
COMPARISON OF PATIENTS WITH AND WITHOUT ASTHMA OR ASPIRIN-SENSITIVE ASTHMAShinichi Kawabori, Akihito Watanabe, Hiroshi Osanai2001 Volume 40 Issue 2 Pages 124-131

JOURNAL FREE ACCESSSome cases of chronic sinusitis have a poor outcome after endoscopic sinus surgery. Patients with asthma or aspirin-sensitive asthma have been reported to have a poor prognosis. We studied clinicopathological differences among cases with and without asthma or aspirin-sensitive asthma. The following factors were examined: preoperative CT findings, presence of infiltrating cells (eosinophils, neutrophils, lymphocytes and plasma cells) in the ethmoid sinus mucosa, number of eosinophils in the peripheral blood, and nasal polyp size. Eosinophil and plasma cell positivity, the number of eosinophils in the peripheral blood, and the size of nasal polyps were significantly different among the three groups. Eosinophil positivity was weakly corrected with both the number of eosinophils in the peripheral blood and the size of the nasal polyps in all patients. A strong correlation between eosinophil positivity in the ethmoid sinus mucosa and in the nasal polyps was also observed. In patients without asthma or aspirin-sensitive asthma, no significant correlations were observed.
Patients without asthma who are positive for eosinophils in the ethmoid sinus mucosa are thought to have a local mechanism that results in eosinophil accumulation, while patients with asthma or aspirin-sensitive asthma are thought to have both local and general mechanisms of eosinophil accumulation.View full abstractDownload PDF (1181K)
