RESUMO
BACKGROUND: Affected tooth conservation is an often-overlooked problem in odontogenic sinusitis (ODS) treatment. Treatable dental conditions are improperly managed with extractions imposing an unnecessary health burden on patients. Furthermore, no down-to-earth protocols have been proposed for the clinical management of these patients. AIM: This study aims to prospectively validate a treatment protocol for ODS based on dental mobility, an indirect sign of poor long-term tooth survival. The protocol suggests endoscopic sinus surgery (ESS) alone followed by dental treatment for immobile affected teeth, and concomitant ESS and extraction for mobile teeth. Extraction of immobile teeth is considered if inflammation persists after the treatment. MATERIAL AND METHODS: Forty cases treated with our protocol were prospectively examined about ODS cure and preservation of affected teeth. RESULTS: Among the 35 patients with immobile affected teeth, only one required extraction for complete ODS cure after ESS. All five cases with mobile teeth and one with postoperative extraction had marginal periodontitis. CONCLUSION AND SIGNIFICANCE: Ninety-seven percent of immobile affected teeth were preserved with complete ODS cure in this study. In case marginal periodontitis is present, extraction is likely to be necessary, although ESS should be prioritized over blanket extractions to preserve the teeth for patients' quality life.

OBJECTIVES: To evaluate the efficacy of high-dose corticosteroid for severe acute facial paralysis in children. METHODS: The present study enrolled 10 pediatric patients with House-Brackmann (H-B) Grade VI facial paralysis who received prednisolone (PSL) 3 to 4 mg/kg/d for 2 to 3 days followed by a 10-day taper (the child high-dose group). Eight pediatric patients who received PSL 0.5 to 1 mg/kg/d were enrolled in a child low-dose group, and nine adult patients (25-64 yr) who received a high-dose PSL 200 mg equivalent for 2 to 3 days followed by a 10-day taper were enrolled in an adult high-dose group. On the initial and follow-up visits, facial movements were evaluated using the H-B grading system. The degree of oral-ocular synkinesis was evaluated by the degree of asymmetry in eye-opening width during mouth movements. The synkinesis index was defined as a percentage of the interpalpebral space width ([normal side - affected side]/normal side). RESULTS: The child high-dose group achieved a significantly better H-B score than the child low-dose group ( p < 0.01). The synkinesis index was significantly lower in the child high-dose group than in the child low-dose group or the adult high-dose group ( p < 0.05). CONCLUSION: Children receiving PSL 3 to 4 mg/kg/d achieved better recovery and less synkinesis than those treated with low-dose PSL (0.5-1 mg/kg/d).

OBJECTIVE: The present study aimed to investigate whether hearing aid use can induce improvement as acclimatization effect in unaided speech perception in patients with age-related hearing loss. METHODS: Fifty ears in 41 patients (age range: 65-91 years) diagnosed as age-related hearing loss were enrolled in this study. They used hearing aids for more than 8 hours per day. Unaided speech audiometry using 67-S Japanese monosyllabic word list was performed one or two years after the commencement of hearing aid use. The changes in the unaided speech discrimination score before and after the commencement of hearing aid use were analyzed. To investigate factors for improvement, the patients' backgrounds in terms of age, sex, pure tone average, unaided maximum speech discrimination score, fitting period (one year/two years), fitting ear (bilateral/unilateral), audiogram type (flat-type/other-type), and the level of amplification were also analyzed. RESULTS: Significant improvement in the unaided speech discrimination score after hearing aid use was seen only in the flat-type audiogram group. More than half of older patients in the flat-type audiogram group improved their unaided maximum speech discrimination score 10 % or more. The analysis of aided hearing thresholds revealed that the flat-type audiogram group had significantly lower thresholds of 3kHz and 4kHz than the other-type audiogram group. The age, sex, pure tone average, fitting period, fitting ear, functional gain were not influential factors for improvement. On the other hand, unaided maximum speech discrimination score before using hearing aid and aided hearing threshold at 4kHz had a negative correlation with improvement. CONCLUSION: The findings suggested that older patients with age-related hearing loss whose audiogram is a flat type can benefit from amplification as means of improving their unaided speech perception since flat-type audiogram can be more easily adjusted to sufficiently amplify speech sound at high frequencies. It should be considered that the potential for experience-dependent plasticity is retained even in older adults.

Objectives: To investigate the relationship between cleft width and otitis media (OM) and to determine whether a wide cleft palate (CP) is a risk factor of the incidence, type, amount of middle ear effusion, and prolonged morbidity in OM. Study Design: Retrospective cohort study. Methods: Children with CP who underwent palatoplasty between 2014 and 2018 were analyzed. Cleft width was measured at palatoplasty. The incidence of otitis media with effusion (OME) and acute otitis media (AOM), the type and amount of middle ear effusion, and OME duration and age at resolution were assessed in relation to cleft width. Results: One hundred eighteen children were included. The CP types were Veau I in 16, II in 35, III in 48, and IV in 19 patients. The incidence of OME and AOM before palatoplasty was 83.1% and 49.2%, respectively. Cleft width did not differ significantly between patients with or without OME but was significantly greater in those with, than in those without, AOM (p < .001), in those with mucoid, than in those with serous, effusion (p = .012), and in those with complete, than in those with partial, effusion (p = .01). Regardless of cleft width or type, OME persisted for a median duration of 50 months. Conclusions: Cleft width was significantly associated with the incidence of AOM and the type and amount of middle ear effusion before palatoplasty. However, it was not significantly related to the incidence, age at resolution, or duration of OME. Regardless of cleft width or type, OM in children with CP requires long-term follow-up. Level of Evidence: 2b.
RESUMO
Acquired factor V inhibitor (AFVI) is a very rare disease. We presented herein a case of hypopharyngeal cancer in which AFVI developed after nivolumab administration. Blood test findings two weeks after the first dose of nivolumab showed a significant prolongation of prothrombin time (PT) and activated partial thromboplastin time (APTT), indicating a marked abnormality in the coagulation function. Factor V activity had decreased significantly and was below the detection limit (<3%), and the factor V inhibitor level was as high as 16 Bethesda units (BU)/mL. His underlying illness was a malignant tumor, but we considered that nivolumab administration was the cause of AFVI, considering the time when coagulation abnormality developed. No significant bleeding tendency was observed in the subsequent course, and the AFVI was followed up without treatment. To the best of our knowledge, the present study is the first to report AFVI occurrence after immune checkpoint inhibitor administration.
RESUMO
BACKGROUND: We report the case of a patient with smoking-induced radiation laryngeal necrosis (RLN) after undergoing definitive radiotherapy (RT) alone for T1a glottic squamous cell carcinoma. CASE: The patient was a 63-year-old man who had a history of heavy smoking. He quit smoking when he was diagnosed with glottic squamous cell carcinoma. The RT dose was 63 Gy, delivered in 28 fractions with the three-dimensional conventional RT technique for the larynx. After RT completion, the initial treatment response was complete response. He then underwent follow-up examinations. At 13 months after RT, the patient resumed smoking. At 2 months after resuming smoking, he had severe sore throat and hoarseness. Laryngoscopy revealed a large tumor in the glottis. Surgical excision was performed, and the patient was histologically diagnosed with RLN, as late toxicity without cancer recurrence. At 3 weeks postoperatively, the patient had dyspnea, and laryngoscopy revealed total laryngeal paralysis. Thus, he underwent an emergent tracheostomy. The administration of steroids affected RLN, and laryngeal paralysis gradually improved. CONCLUSIONS: This case suggests that smoking may have the potential to induce RLN after RT. Moreover, continuing smoking cessation is significantly important for patients with glottic cancer who receive RT. Rather than leaving smoking cessation up to the patient, it would be necessary for clinicians to actively intervene to help patients continue their effort to quit smoking.

OBJECTIVES: To evaluate the efficacy of mirror biofeedback rehabilitation for synkinesis in severe acute facial paralysis in children. METHODS: Eight pediatric patients with facial paralysis with an initial electroneurography (ENoG) value less than 10% who underwent mirror biofeedback rehabilitation (the child-rehabilitation group) were enrolled. Seven infants (under age 2âyr) who were unable to undergo rehabilitation (the infant-and-toddler control group) and adult patients (nâ=â13, range, 33-56âyr) who underwent rehabilitation (the adult-rehabilitation group) comprised the control groups. All the patients enrolled were baseline House-Brackmann (H-B) grade VI at onset. The patients began daily facial biofeedback rehabilitation using a mirror at the first sign of muscle contraction on the affected side and were instructed to keep their eyes symmetrically open using a mirror during mouth movements. The training was continued for 12âmonths after the onset of facial paralysis. The degree of oral-ocular synkinesis was evaluated by the degree of asymmetry in eye opening width during mouth movements. The synkinesis index was calculated as a percentage of the interpalpebral space width ([normal side - affected side]/normal side). Statistical analyses used non-parametric tests (the Kruskal-Wallis test and Steel-Dwass posthoc test). RESULTS: The synkinesis index was significantly lower in the child-rehabilitation group than in the infant-and-toddler control group or the adult-rehabilitation group (pâ<â0.001). CONCLUSION: Children who underwent mirror biofeedback rehabilitation had less synkinesis than the infant-and-toddler control group, suggesting that mirror biofeedback rehabilitation is more effective in preventing the exacerbation of synkinesis in children.

We herein report a case of T-cell/histiocyte-rich large B-cell lymphoma which initially presented as a self-limiting T-lymphoproliferative disorder involving multiple extranodal and extrapulmonary organs, such as the salivary gland, the liver, and the central nervous system. Repeated biopsies only revealed polyclonal T-lymphocytosis without the presence of atypical B-cells. Angiocentric cellular infiltration was absent, thus ruling out lymphomatoid granulomatosis. A recurrence in the lymphatic system finally revealed a small population of pathognomonic atypical B-cells, which led to the diagnosis. The clinical dilemma in the diagnosis and management of this indeterminate condition points to limitations in the current nosology.
RESUMO
OBJECTIVE: Substernal goiters are classified as primary or secondary intrathoracic goiters. Here, we report the diagnosis, symptoms, treatment, and postoperative complications of 44 substernal goiters (2 primary mediastinal goiter and 42 secondary mediastinal goiters). METHODS: A retrospective chart review of 351 patients undergoing thyroidectomy at the Department of Otolaryngology-Head and Neck Surgery of the Tokyo Metropolitan Tama Medical Center. Between 2009 and 2015, 44 patients underwent surgery for substernal goiter. RESULTS: The frequency of primary and secondary mediastinal goiters was 0.5% and 11.9%, respectively. The preoperative symptoms were neck mass, dyspnea, and dysphagia. Eight patients were asymptomatic. Thirty-nine patients had benign masses and 5 patients had malignant masses. Most patients were operated on for adenomatous goiters (52.2%). In ten cases beyond the aortic arch, the tumors were benign and there were eight cases of adenomatous goiter. All patients underwent a successful transcervical incision without sternotomy. Even the primary intrathoracic goiters were extracted after total thyroidectomy via the cervical approach without complications. Although one case showed unilateral recurrent nerve paralysis as a postoperative complication, phonetic function improved in 6 postoperative months. No instances of postoperative bleeding or definitive hypoparathyroidism occurred, and tracheostomy was not performed in any of the cases. CONCLUSION: The cervical approach was safely performed in almost all substernal goiters without an extracervical procedure. Selected cases of primary mediastinal goiter may be excised via the cervical approach.

OBJECTIVES: After tuberculous pleurisy, lymphadenitis arising from cervical lesion is the second most common form of extrapulmonary tuberculosis. It is generally treated with antituberculosis agents, but some patients resist chemotherapy. In such cases, surgical resection is often considered as an alternative treatment. This study aims to evaluate the therapeutic outcome of cervical tuberculous lymphadenitis and the future course of treatment of this disease. METHODS: We retrospectively reviewed the clinical charts of patients diagnosed at the Tokyo Metropolitan Tama Medical Center between 2009 and 2015 and identified 38 cases of cervical tuberculous lymphadenitis. Precisely 798 patients were registered for primary tuberculosis at our institution during the same period. RESULTS: Patient ages ranged from 21 to 85 years (average: 58.9 years), and the male-to-female ratio was 1:1.2. The range of tuberculosis progression was as follows: 30 (78.9%) in only the cervical lymph node, 3 in the other (axillary, mediastinal, and abdominal) lymph nodes, 1 in the lung and vertebrae lumbales, 2 in the lung, and 1 in the pleural membrane. All 38 patients were initially treated with antituberculous drugs at the Department of Pulmonary Medicine based on guidelines for tuberculosis cases in Japan. In seven cases, the antituberculous drugs were replaced due to side effects. Four cases involved a single drug-resistant strain, and one case involved a double drug-resistant strain. Thirty-three (86.8%) cases were cured by chemotherapy alone. The three patients resistant to chemotherapy were successfully treated through neck dissection. Thirty-six cases (94.7%) were cured by chemotherapy or chemotherapy and surgery. CONCLUSION: Local therapy could prove effective in cervical tuberculous lymphadenitis patients who exhibit an inadequate response to drugs. The role of neck dissection in cervical tuberculous lymphadenitis remains an important consideration.

Hemangiomas in the infratemporal fossa (ITF) are extremely rare benign vascular tumors. For many tumors of the ITF, with the exception of some small hemangiomas, a lateral facial approach has often been required. Recently, however, there have been some reports that minimally invasive endoscopic surgery can be used in the ITF; this would reduce the risk of surgical complications. To date, there has been no report of a hemangioma of the ITF exceeding 6 cm being resected by the endoscopic approach without facial incisions. Here, however, we report two cases of ITF hemangiomas that were completely extracted endoscopically, using a transmaxillary and transoral approach, without facial incisions or surgical complications.

The majority of lymphomas of the head and neck in children present as an enlarged cervical lymph node; however, malignant lymphoma arising from the thyroid gland is extremely rare. We report a case of a 12-year-old child who was admitted to our hospital because of a history of rapidly progressive anterior neck swelling. Histopathological studies revealed this case to be T-cell lymphoblastic lymphoma. We performed chemotherapy and the patient has kept recurrence-free survival for 18 months after the beginning of the treatment. This is the 2nd case of T-cell lymphoblastic lymphoma in the thyroid gland in a child.
RESUMO
OBJECTIVES: Laryngotracheal separation is a surgical procedure used in the treatment of intractable aspiration. As with total laryngectomy and laryngotracheal diversion, this procedure requires postoperative pressure above the suture location to prevent leakage at the anastomosis. To date, there have been no reports regarding laryngeal separation without postoperative treatment. The purpose of this study was to evaluate a new surgical procedure for laryngotracheal separation that is performed without a cannula and requires no postoperative treatment. METHODS: We performed the new surgical procedure in 7 patients. The mucosa of the cricoid cartilage was sutured to achieve tracheal closure. The closure was covered with a musculocutaneous flap of strap muscle; gauze was then tied over the skin and a 2-0 nylon suture was used to pierce the posterior part of the cricoid cartilage. In addition, a permanent tracheostoma was constructed without a tracheal cannula. RESULTS: No patients required a tracheal cannula or treatment after the operation. Additionally, aspiration pneumonia was prevented without complications in all patients. CONCLUSIONS: This new surgical procedure eliminates the need for a cannula and postoperative treatment. The effects of this method in terms of aspiration prevention are comparable to those of other surgical techniques.

A procedure for laryngotracheal separation was performed on 5 elderly patients in poor general condition to prevent habitual aspiration pneumonia. Intractable aspiration was relieved in all the patients with no major postoperative complications. In this intervention, a modification of the procedure previously reported, the anterior part of the tracheal and cricoid cartilage was removed, and the subglottic mucosa was sutured to fashion a blind pouch. This procedure could be adjusted even in cases of severe laryngoptosis or after high tracheostomy. Laryngotracheal separation is likely to be useful as a simple and safe procedure even for older patients. If this comes to be, it will serve as a valuable intervention in today's aging society.

The use of an endoscope in nasal surgery has now extended to surgery on the nasal septum as well as to sinus surgery. We devised the use of the modified nasal specula with Yasargil's flexible holder to resolve the technical problems in using an endoscope for septal surgery. One nasal speculum has two plates for connecting to the Yasargil's flexible holder. This speculum allows the surgeon to use both hands freely and also functions as a guide for stabilizing an endoscope. Another nasal speculum has two long adjustable wings. This speculum can widen the working space between the cartilage or bone of the nasal septum and detached mucosa. Our modified nasal specula are readily applicable to resolve the problems such as unstable endoscope and narrow working space in septal surgery under endoscopic view.

BACKGROUND: Nasal airway remodeling exists in allergic rhinitis, but it appears to be far less extensive than in asthma. However, there has been little study about nasal airway remodeling and no study using mice models. It has been reported that airway hyperresponsiveness decreased after prolonged allergen challenge in a chronic murine asthma model together with the progression of remodeling. However, there has been no study of the relation of remodeling and airway responsiveness in nasal allergy. Therefore, we have undertaken this investigation to characterize nasal airway structural changes after prolonged allergen challenge and to examine the relationship between nasal airway hyperresponsivity and remodeling. METHODS: We prepared murine allergic rhinitis for ovalbumin. Mice were subsequently challenged three times a week with ovalbumin from day 19 to days 53, 88, and 130. We examined allergen-induced nasal symptoms and objective nasal hyperresponsiveness using the enhanced pause system. Moreover, the pathologic changes were investigated after allergen challenge. RESULTS: The extended allergen challenge protocol caused significant nasal airway remodeling. Specifically, remodeling was characterized by goblet cell hyperplasia and deposition of collagen in the submucosal area. Allergen-induced nasal hyperresponsiveness was first increased but gradually decreased in nasal symptoms and Penh after prolonged allergen challenge. CONCLUSIONS: We have demonstrated that a remodeling of nasal mucosa in a murine allergic rhinitis model prolonged allergen exposure. Moreover, prolonged allergen exposure induced a reduction of nasal hyperresponsiveness together with a progression of nasal remodeling.

CONCLUSION: This study suggested that nitric oxide (NO) takes part in the parasympathetic nerve control functions mainly through m3 receptors and subsequently through m1 receptors. OBJECTIVES: The regulation of glandular secretions and vasomotor tone in human nasal mucosa implicates muscarinic receptors. There are five recognized classes (m1-m5) of muscarinic receptor subtypes. NO is a free radical gas that has been found to be produced in neuronal cells by the action of enzyme neural nitric oxide synthase (nNOS). The aim of this study was to identify the colocalization of muscarinic receptor subtypes (m1-m5) and nNOS in the human inferior turbinate mucosa. MATERIALS AND METHODS: Human inferior turbinate mucosa was stained by using the antibody of muscarine receptor subtypes and nNOS in an immunohistochemical double-staining method. RESULTS: The colocalization of m3 receptors and nNOS-immunoreactive nerve fibers was most extensively distributed on glands, vessels, and epithelium in all muscarinic receptor subtypes. These findings lead us to propose that NO also acts as a neurotransmitter in glands, vessels, and epithelium of the human nasal mucosa and can be assigned to parasympathetic nerve structures through m3 receptors mainly and m1 receptors subsequently.
