Clinical availability of a self-administered odor questionnaire for patients with olfactory disorders.

Objective: This study demonstrated statistical correlations between a novel self-administered odor questionnaire (SAOQ) and other olfaction tests in patients with olfactory disorders, and the usefulness of this questionnaire was discussed.

Materials And Methods: Between December 2004 and November 2009 (5 years), the SAOQ was completed by 405 healthy people without any nasal diseases (Group A) and 539 patients with an olfactory disorder (Group B) at the Department of Otolaryngology, Hyogo College of Medicine. This was a prospective study.

[Clinical features of patients with paranasal sinus cysts].

This study retrospectively analyzed the clinical features of patients with paranasal sinus cysts. Between April 1995 and March 2008 at Hyogo College of Medicine, we performed sinus surgery on 218 patients with paranasal sinus cysts. There were 125 men and 93 women with the mean age of 57.

Difficulty of diagnosing Wegener's granulomatosis in the head and neck region.

Objective: The objective of this study was to review the various clinical features associated with Wegener's granulomatosis (WG) in the head and neck region and to discuss the difficulty of diagnosing patients with early stage WG.

Methods: Between January 1998 and August 2007, WG was diagnosed and treated in 16 patients at the Department of Otolaryngology, Hyogo College of Medicine. Clinical and operating records of these patients were analyzed retrospectively.

Taste function after section of chorda tympani nerve in middle ear surgery.

Objective: To investigate prospectively the clinical manifestations and the functional recovery of taste after section of chorda tympani nerve (CTN) during middle ear surgery, the subjective and objective study on the patients was performed.

Methods: Thirty-five patients underwent surgery with unilateral (n=32) or bilateral (n=3) section of CTN between January 2000 and April 2002. The patients were asked about taste symptoms before surgery and 2 weeks and 2 years after surgery.

Reevaluation of bilateral same-day surgery for bilateral perforated chronic otitis media.

Objective: To evaluate the results of bilateral same-day surgery for bilateral perforated chronic otitis media in comparison with our previous report.

Study Design: Prospective study.

Patients: Seventeen patients ranging in age from 5 to 70 years (mean, 52.

Observation of tongue papillae by video microscopy and contact endoscopy to investigate their correlation with taste function.

Objectives: Contact endoscopy is a technique used to obtain detailed images of living epithelium in the fields of gynecology, rhinology and laryngology. Video microscopy is useful for observation of the surface of tongue papillae. In the present study, we attempted to apply the contact endoscopy technique together with video microscopy to observe tongue papillae, and to study the correlation between the condition of fungiform papillae and taste function.

Usefulness of the odor stick identification test for Japanese patients with olfactory dysfunction.

The odor stick identification test (OSIT) is a new test of olfactory function recently developed for Japanese people. The purpose of the present study was to evaluate this test in relation to T&T olfactometry and the cross-cultural smell identification test (CC-SIT) by applying to 110 Japanese patients with olfactory disturbance. The averaged recognition thresholds for five odorants in T&T olfactometry, the number of correct answers in the CC-SIT and the rates of identification of 13 odorants in the OSIT were compared.

Clinical study of flavor disturbance.

Objective: We have observed that, in cases of smell loss, patients often complain of taste loss as well even though they actually have normal gustatory acuity according to gustatory tests; we have defined such symptoms as "flavor disturbance". The clinical features of flavor disturbance are reported in this paper.

Material And Methods: A total of 297 patients (99 males, 198 females; mean age 55.

Rate of recovery of taste function after preservation of chorda tympani nerve in middle ear surgery with special reference to type of disease.

To study the recovery of function of the chorda tympani nerve, we examined by electrogustometry 79 patients (83 ears) with both preoperative normal function of the nerve and operative preservation of the nerve, every 2 days during hospitalization and at 6 months after surgery. For symptoms such as tongue numbness and taste disturbance, patients with noninflammmatory (NI) diseases (13/20 or 65.0%) showed a significantly higher rate of symptoms than did patients with chronic otitis media (COM; 13/35 or 37.

Expression of activating transcription factor 3 and growth-associated protein 43 in the rat geniculate ganglion neurons after chorda tympani injury.

The purpose of this study was to evaluate the degree of damage in the geniculate ganglion and its target organ as a result of chorda tympani (CT) injury. We performed unilateral transection of the rat CT and examined expression of the activating transcription factor 3 (ATF3), a neuronal injury marker, and the growth-associated protein 43 (GAP-43), a regeneration-associated molecule. The mean proportion of ATF3-immunoreactive (ir) neurons in the geniculate ganglion was approximately 32% at 3 days after CT injury, but these neurons were never detected in the naive ganglion.

Olfactory acuity after total laryngectomy.

The olfactory acuity of 29 patients receiving laryngectomy was prospectively studied. The olfactory acuity was evaluated by Jet Stream Olfactometer (JSO) and Alinamin test preoperatively and at 3, 6 and 12 months postoperatively. The findings of nasal/olfactory mucosae were also observed by rigid endoscope.

Olfactory dysfunction in patients with head trauma.

Objective: There are few reports about following up olfactory acuity of the patients who have post-traumatic olfactory dysfunction. In this study, we studied about patients with post-traumatic olfactory dysfunction for a short period under a treatment.

Methods: The olfactory function of 27 patients with head trauma was studied.
