JOURNAL FREE ACCESSThe resection of the posterior nasal nerve is an effective surgical treatment for intractable allergic rhinitis. We retrospectively analyzed the usefulness of a surgical navigation system for this surgery. The subjects were 28 consecutive patients with allergic rhinitis/rhinosinusitis who underwent resection of the posterior nasal nerve via an endoscopic endonasal approach between April 2004 and May 2009. These patients were 22 males and six females aged 14-63 years, with an average of 26.2 years. The optical navigation system, Vector Vision Compact, was used after March 2007 for 17 patients (10 males and five females aged 14-47 years, with an average of 22.7 years；navi(+) group), but was not used before then for the other 13 patients (12 males and one female aged 16-63, with an average of 30.0 years；navi-(-) group). The length of the operation did not differ significantly between the two groups (210 ± 53 min in the navi-(-) group, 199 ± 52 min in the navi-(+) group；ρ=0.71). However, the blood loss showed a tendency to be lower in the navi-(+) group than in the navi-(-) group (143 ± 132 vs. 238 ± 209 mℓ； p=0.09). Our results suggest that the surgical navigation system is helpful for detecting and revising the recognition error of the anatomical position, and thereby improves the accuracy and safety of resection of the posterior nasal nerve.View full abstractDownload PDF (765K) -

JOURNAL FREE ACCESSSleep Disordered Breathing (SDB) are characterized by nocturnal respiratory instability during sleep, and obesity is thought to be the most important factor for this disease. We paid special attention to the adipose tissue around the tongue and pharynx as a possible cause of the narrowing of the upper respiratory tract. There have been few previous reports comparing the fat in the pharynx to the increase of abdominal fat. In this study, to investigate the pathogenesis of SDB, we examined the relationship between the patterns of fat deposition in the abdomen and pharynx. On plane CT of 20 patients with SDB and 10 control patients, the pattern of fat deposition was estimated at the level of pharynx and abdomen. In the cases with SDB, the visceral fat was predominant, even in patients with a low Body Mass Index (BMI), compared to the predominant subcutaneous fat in control cases. These findings indicate that the pattern of abdominal fat deposition in SDB differs from that in control cases. In SDB patients, the rate of pharyngeal fat decreased as the BMI increased. In contrast, in control cases, the rate of pharyngeal fat tended to increase as the BMI increased. These findings also indicate that there is a discrepancy in the pattern of pharyngeal fat deposition between patients with SDB and the controls. As the rate of pharyngeal fat deposition was decreased in SDB, despite the increase of the apnea hypopnea index, other factors, such as the fat in the tongue or the base of the tongue, might also play an important role in patients with sleep breathing disorders.View full abstractDownload PDF (875K) -

JOURNAL FREE ACCESSWe retrospectively investigated the clinical features and treatment outcomes of 164 cases of laryngeal cancer primarily treated at our hospital between 2002 and 2009.Of the 164 patients, 126 had glottic type tumors, 34 had supraglottic type and four had the subglottic type. Double cancer, including simultaneous and metachronous occurrence, accounted for 22.6% of all cases. The three-year overall survival rate was 93.8% for all cases, 96.0% for glottic type cases and 93.9% for the supraglottic type cases. The three-year larynx preservation rate was 70.1% overall, but was low in the advanced T cases, such as T3 (15.6%) and T4 (7.7%). The recurrence of the primary lesion occurred in 24 cases (14.6%), but 87.5% of these cases were cured by a salvage operation. No significant difference in the survival rates between the patients treated using different treatments were noted for T2 and T3 cases, so that CCRT was recommended as the first treatment. In order to improve the larynx preservation rate, it is necessary to change the regimen of chemotherapy for CCRT, and to introduce larynx-preserving operations for cases with local recurrence and radioresistant tumors.View full abstractDownload PDF (821K) -

JOURNAL FREE ACCESSWe herein report a case of transient thyroid swelling which occurred after fine needle aspiration cytology (FNAC) of an adenomatous goiter. A 71-year-old man was diagnosed with nodular goiter of the left lobe of his thyroid gland at another hospital, and was referred to our hospital because the thyroid had increased in size. He has no history of allergy. FNAC was performed with a 22-gauge needle on the left lobe. 3 hours later, he complained of swelling and pain in the neck. No airway obstruction was observed. The next day, the tumor in the left lobe was observed to have swollen from 30 mm to 40 mm in size on US. Both steroids and antibiotics were administered orally,and the symptoms improved within a few days. We thereafter performed a partial thyroidectomy, and the patient was discharged without any complications. Inflammatory cell infiltration and a bacterial colony were identified pathologically. The mechanisms for the observed swelling, such as allergy, infection, and hemorrhaging were suspected. The occurrence of swelling of the thyroid following fine needle aspiration is discussed.View full abstractDownload PDF (665K) -

JOURNAL FREE ACCESSSarcoidosis is a multisystem inflammatory disease of unknown etiology, characterized by the presence of noncaseating granuloma. Neurosarcoidosis affects about 5% of the patients with sarcoidosis. The disease is also known to rarely bring on hearing loss, but the pattern of hearing loss varies greatly. We retrospectively evaluated the hearing loss in 24 patients diagnosed with sarcoidosis, who consulted our department in the past decade. Three patients had symptoms of hearing loss, and we herein discuss the test results of these patients. The results did not show any significant relationship between neurosarcoidosis and hearing loss, but indicated the possibility of a relationship. The accumulation of additional reports and detailed examinations are needed.View full abstractDownload PDF (761K) -

JOURNAL FREE ACCESSWe herein report a case of psychogenesis articulation disorder combined with psychogenic hearing loss. The patient was a 51-year-old female librarian with complaints of hearing loss and an articulation disorder. Two years earlier, she had suddenly developed hearing loss in the right ear, followed gradual hearing loss in the left ear four months before consulting our hospital. At the same time, her family noticed that she had an articulation disorder. Her eardrum was normal. Pure tone audiometry showed serious hearing loss. The threshold of the auditory brain stem response was normal. There were no mechanical problems or central nervous system disorders regarding the articulation organs. The type of error of articulation was a floating error. However, the patient primarily substituted /k/ was for /t/, and /ɡ/ for /d/. In brief conversations, the frequency of the substitution decreased, and normal articulation appeared. Therefore, the articulation disorder was considered to be a disorder of functionality. At home,the patient was social restricted owing to the fact that her younger brother had an intellectual disability. In addition,she felt stress regarding interpersonal relationships at the office. On SPECT, a slight decrease in the blood flow was observed in the bilateral frontal lobes, suggesting a depressive condition. Therefore, we diagnosed the patient's articulation disorder to be a psychogenic articulation disorder.View full abstractDownload PDF (699K)
