    　The clinical characteristics of 16 patients with congenital anosmia were examined retrospectively. MRI (magnetic resonance imaging) was used to assess the morphological changes in the olfactory bulbs and olfactory sulci according to the method of P. Rombaux (2009)7). Congenital anosmia was divided into two forms: syndromic forms in association with a syndrome, and isolated forms without evidence of other defects8). Only three patients (19%) in our series had syndromic forms of congenital anosmia, such as the Kallmann syndrome. Most cases (13 patients, 81%) had isolated congenital anosmia. Psychophysical testing of the olfactory function included T&T olfactometry and the intravenous Alinamin test, which are widely used in Japan. In T&T olfactometry, detection and recognition thresholds for the five odorants are used to assign a diagnostic category representing the level of olfactory function. Most cases (14 patients, 88%) showedoff-scale results on T&T olfactometry, and the Alinamin test resulted in no response in all 11 patients who underwent the test. Abnormal MRI findings of the olfactory bulbs and sulci were detected in 15 of 16 patients (94%). Olfactory bulbs were bilaterally absent in nine patients (56%), and two patients (13%) had unilateral olfactory bulbs. Four patients (25%) had bilateral hypoplastic olfactory bulbs, and only one patient had normal olfactory bulbs (6%). The olfactory sulcus was unilaterally absent in one patient (6%), and nine patients (56%) had bilaterally hypoplastic olfactory sulci. Two patients (13%) had a unilateral normal olfactory sulcus and hypoplastic olfactory sulcus. Three patients (19%) had normal olfactory sulci. Quantitative analysis showed that the volume of olfactory bulbs varied from 0 mm3 to 63.5mm3, with a mean volume of 10.20±18mm3, and the mean depth of the olfactory sulcus varied from 0 mm to 12.22 mm, with a mean length of 4.85±4.1mm. Currently, there is no effective treatment for congenital anosmia. However, diagnosis of congenital anosmia is important, as its presence can lead to dangerous situations. Careful examination for hypogonadism is also required in people with anosmia. MRI examinations of the olfactory bulbs and sulci were useful for the diagnosis of congenital anosmia.

    　Objective: The aim of this study was to describe a new titanium thyroplasty medializing implant and evaluate its usefulness.
    　Material and method: Retrospective study of 9 male patients with severe unilateral vocal fold paralysis after aortic-aneurysm surgery who underwent type I thyoplasty with arytenoid adduction under general anesthesia. Preoperative and postoperative glottal closure and voice function were evaluated by acoustic analysis (Jitter %, Shimmer %, NHR), stroboscopic findings, maximum phonation time, mean airflow rate, voice handicap index and computed tomography findings. These tests were evaluated before and 3 months after surgery.
    　Result: All acoustic parameters improved after surgery. In stroboscopic findings, symmetrical mucosal waves were identified in 3 cases. Maximum phonation time prolonged, mean flow rate decreased and voice handicap index improved. In computed-tomography findings, breakage, deformation, dropped and migration of titanium plate were not identified.
    　Conclusion: In surgery of vocal fold paralyzed patient, it is necessary to reconstruct vocal fold in physiological state at the time of phonation. Using the titanium plate developed for this purpose, all patients obtained good vocal improvement.

    　Objective: Carcinoma of the ethmoid sinus is very rare, and treatment for locally advanced tumors remains as a formidable challenge to the clinician. We reviewed cases of ethmoid carcinoma in which anterior craniofacial resection had been undertaken and evaluated the safety and validity of the operative methods.
    　Methods: We retrospectively reviewed 13 patients with ethmoid carcinoma who underwent combined anterior craniofacial resection. We evaluated the surgical procedures, complications, outcomes, local recurrence, and the survival rate.
    　Results: Coronal incision and anterior craniotomy were performed in all cases. Four out of 13 cases underwent ipsilateral orbital exenteration due to involvement of the orbital contents. There were no potentially fatal complications, except for two cases of epidural abscesses which were successfully cured. Positive surgical margins were observed in 6 patients, and they received postoperative radiotherapy and/or chemotherapy. Local recurrences occurred in 4 cases, and 3 died at 9, 11, and 49 months after the surgery. Distant metastasis was not observed during the observation period. The overall 5-year survival rate was 75.2% (Kaplan-Meier method).
    　Conclusion: These tumors were safely removed without severe complications and postoperative mortality. Combined anterior craniofacial resection is an effective and safe option for treatment of locally advanced ethmoid carcinomas after various preoperative treatments.

    　Hyponatremia is one of the electrolyte abnormalities frequently encountered in cancer therapy. Cisplatin is a well-known drug which can raise various adverse events, including hyponatremia. A male with advanced oropharyngeal cancer is presented in the present report, who was treated with radiotherapy with concurrent administration of cisplatin and who underwent a total of three episodes of severe hyponatremia in the course of therapy. The first two attacks of hyponatremia following cisplatin administration were accompanied by dehydration and excessive urination, and the patient recovered in one week with rehydration and salt supplementation. Excessive loss of salt in urine confirmed that these events were caused by renal salt wasting syndrome after cisplatin administration. On the other hand, the third attack was due to the syndrome of inappropriate antidiuretic hormone secretion after surgery for a bone fracture. Estimation of the extracellular fluid volume and salt intake/output balance is always believed to be necessary for the diagnosis and proper management of severe hyponatremia after chemotherapy-based treatment with cisplatin.

    　The elderly population has been increasing, in Japan. With this increase, the incidence of elderly patients with head and neck cancer is likely to increase concomitantly. Therefore, a strategy for addressing this problem must be defined. In this study, a questionnaire for head and neck cancer specialists, certified by the Japanese Society of Head and Neck Surgery, is analyzed.
    　The survey was conducted in 225 head and neck cancer specialists, and 122 answers were complete and bare analyzed in this study. Comorbidity was found to be the most important factor in decision making for head and neck cancer, even though it is subclinical. Especially important was the cognitive state, the dysfunction of which might decrease the feeling of struggle against the disease. These results indicate that we must choose the appropriate treatment based on the evaluation of the physical and emotional condition of the patients and their families, not only on their age. However, this suggestion includes some problems, such as the fact that the criteria are not definite and the choice of the treatment might be at risk of being judged by only one doctor.

    　In 2012, we carried out a study in a large sample to understand the secondary injuries caused during the taking ear impressions for hearing aids. This study is a follow-up of previous research conducted in 1986 (285 medical institutions) and 1999 (98 medical institutions). We posted a questionnaire survey to the otolaryngology departments of 3,257 medical institutions. The response rate to the questionnaire was 62.9% (2,050 of the 3,257 institutions), and the results indicated that 301 of the 2050 institutions (14.7%) had experience with secondary injuries, with a total of 460 cases reported. In 342 of the 460 cases (74.3%), the secondary injuries occurred at hearing-aid dealerships, followed by 67 cases (14.6%) at affiliated medical institutions, and 51 cases (11.1%) in other locations, including other medical institutions, rehabilitation counseling centers, and educational institutions. The most common type of secondary injury (298 cases, 64.8%) was caused by the presence of foreign bodies in the ear, which in turn was a result of complications occurring during the removal of residual ear impression material. Of these 298 cases, 32 required excision of the foreign bodies and surgical intervention under general anesthesia. The remaining 10 cases exhibited isolated tympanic membrane perforation without foreign body-related complications. Furthermore, 146 cases (31.7%) developed bleeding and otitis externa following removal of the ear impression, and there were reports of cases with bleeding that required long-term outpatient care and treatment. Therefore, since retention of a foreign body in the ear and tympanic membrane perforation can occur even in patients without a history of surgery or prior otologic history, adjustment of hearing aids requires prior otorhinolaryngological examination. Furthermore, because of the risk of secondary injury when taking ear impressions, this procedure must be performed with caution under the guidance of an otolaryngologist.
