ABSTRACT
This study reported two cases of acute life-threatening hemorrhage after Le Fort I osteotomy. In both cases, computed tomography and angiography revealed damage to the descending palatine artery, which was successfully treated by angiographic embolization. Although massive hemorrhage after Le Fort I osteotomy is rare, acute hemorrhage from the postoperative area may occur. Angiographic embolization is useful in cases of such hemorrhage from the posterior nasal cavity where endoscopic hemostasis is not possible.
ABSTRACT
Inverted papilloma is the most common benign tumor of the paranasal sinuses with the possibility of malignant transformation. On the one hand, adenoid cystic carcinoma (ACC) is a rare malignant neoplasm that arises from the secretory glands. Sinonasal ACC accounts for 10%-25% of all head and neck ACC. This neoplasm is defined by its distinctive histologic appearance. Surgical resection, whenever possible, is the mainstay therapy. An association between inverted papilloma and malignancy is controversial. A synchronous carcinoma has been established at diagnosis in 3.3%-11% of cases, and the risk of metachronous carcinoma is <3%. We report a case of an 84-year-old female affected with sinonasal inverted papilloma associated with synchronous ACC. She had right nasal obstruction due to the rapid growth of the tumor. She was referred to our department for further workup. A frozen biopsy revealed part of the tumor as ACC. The tumor was consistent with preoperative imaging, and surgical findings also showed infiltration into the orbit. There was no consent for radical surgery with orbital exenteration and adjuvant chemoradiotherapy in consideration of her advanced age. This is the first case report of the association between sinonasal inverted papilloma and ACC within our retrieval capability.
ABSTRACT
OBJECTIVE: Japanese cedar pollinosis is an endemic disease affecting a large proportion of Japan's population. Five seasons have passed since sublingual immunotherapy (SLIT) for Japanese cedar pollinosis was included in the public insurance coverage in Japan. In this study, we evaluated the clinical effects of long-term SLIT for Japanese cedar pollinosis on upper respiratory symptoms primarily represented by nasal symptoms and inflammation of the respiratory tract in the 2019 season, in which considerable amount of cedar pollen was dispersed. METHODS: This study involved 95 patients who were undergoing SLIT for Japanese cedar pollinosis after the initiation at some point between 2014 and 2018, and this group of patients was compared with a control group comprising 21 patients receiving preseasonal prophylactic treatment (with a second-generation antihistaminic drug). We evaluated the patients' nasal/eye symptoms, total nasal symptom and medication score (TNSMS), and quality of life according to relevant guidelines. In addition, the levels of peripheral blood eosinophils, serum total IgE, Japanese cedar antigen-specific IgE, Cryj1-specific IgG4, and fractional exhaled nitric oxide (FENO) were measured as objective indices. RESULTS: From the fourth season (SLIT4), nasal discharge, sneezing, nasal obstruction symptoms, and TNSMS significantly decreased compared with those in the preseasonal prophylactic treatment and SLIT1 groups. In the patients suspected to have eosinophilic airway inflammation (with a baseline FENO ≥25 ppb), the interannual variability of FENO levels significantly reduced after 5 years of treatment. CONCLUSION: The efficacy of SLIT was noted from the first year of treatment, even in a year when pollen profusely dispersed. Thus, long-term continuous treatment with SLIT may alleviate nasal symptoms as well as eosinophilic airway inflammation.
