RESUMEN
PURPOSE: Endoscopic nasal and sinus surgery is a surgical procedure frequently performed by otolaryngologists. Postoperative bleeding is detrimental to both healthcare providers and patients. We investigated the epidemiology of postoperative bleeding during endoscopic nasal and sinus surgery and explored possible bleeding triggers. METHODS: We evaluated the patients who underwent endoscopic nasal and sinus surgery. Data regarding the age, sex, presence of hypertension, and abnormal coagulability, including oral anticoagulants, diagnoses, operative procedures, intraoperative use of drills and blood loss, and postoperative antimicrobial administration of eligible patients, were extracted from medical records and retrospectively reviewed. RESULTS: One hundred and eighty-six patients underwent endoscopic nasal or sinus surgery during the study period, and postoperative bleeding occurred in 9 patients (4.8%). Posterior nasal neurotomy (PNN) was the procedure most likely to cause postoperative bleeding (4 surgeries, 13.3%). Postoperative antimicrobial administration significantly reduced the incidence of postoperative bleeding (p = 0.04). CONCLUSIONS: Postoperative bleeding requiring intervention occurs in 4.8% of cases, and PNN is associated with a high risk of postoperative bleeding. Wound infection is a potential cause of postoperative bleeding, and antimicrobial administration should be considered in addition to local treatment.

PURPOSE: In Japan, two types of tests for diagnosing olfactory disorders, T and T (T&T) olfactometry and intravenous olfactory tests, are covered by insurance and performed on patients with olfactory disorders. This study examined the validity of these olfactory tests and whether psychophysical or morphological tests are more helpful in evaluating olfactory disorders. METHODS: We evaluated patients who visited our department and underwent two types of olfaction tests and sinus computed tomography (CT). Data regarding the age, sex, peripheral blood eosinophil percentage, presence of bronchial asthma, diagnoses, olfactory symptom score, results of the two olfactory tests, and CT findings in eligible patients were extracted from medical records and retrospectively reviewed. RESULTS: One hundred and sixty-three patients underwent all tests during the study period. The results of the T&T olfactometry and intravenous olfactory tests were significantly correlated. However, only the results of T&T olfactometry and olfactory cleft opacification on CT were statistically significant predictors of the olfactory symptom scores. CONCLUSION: T&T olfactometry and CT evaluations of olfactory cleft opacification helped evaluate olfactory dysfunction. It is important to note that intravenous olfactory tests are best performed with careful control and not blindly to assess olfactory disorders.
RESUMEN
Functional endoscopic sinus surgery has become popular worldwide. However, serious complications have been reported with it. A preoperative imaging evaluation is thus essential to avoid complications. The authors compared 0.5 mm slice computed tomography (CT) images reconstructed from sinus CT data with conventional 2 mm slice CT images. The authors evaluated patients who underwent endoscopic surgery. Data regarding age, sex, history of craniofacial trauma, diagnosis, operative procedure, and CT findings of eligible patients were extracted from medical records and retrospectively reviewed. One hundred twelve patients underwent endoscopic surgery during the study period. Six patients (5.4%) had orbital blowout fractures, and half of them could only be identified by 0.5 mm slice CT images. The authors presented the usefulness of 0.5 mm slice CT images in the preoperative imaging evaluation of functional endoscopic sinus surgery. Surgeons should also recognize that a small number of patients have "stealth" (asymptomatic and unrecognized) blowout fractures.

Fibroepithelial polyps are benign tumors of mesodermal origin. They rarely occur in the nasal cavity, with only four such cases reported in the relevant English literature. The location was the inferior turbinate in three cases and anterior nasal septum in one case. The etiology has been suggested in other organs; however, it is entirely unknown in the nasal cavity. Pathological findings play an essential role in the diagnosis of fibroepithelial polyps. We report the case of a 76-year-old woman with fibroepithelial polyps originating from the posterior part of the nasal septum. The fibroepithelial polyps were white-yellow lobular masses that differed from a common inflammatory polyp. We made the diagnosis by excluding the other possible tumors based on a pathological examination. This is the first report about fibroepithelial polyps arising from the posterior nasal septum. She had no potential risk factors that might trigger fibroepithelial polyps in the nasal cavity. This case is a valuable example when considering the potential causes (e.g., female hormones and mechanical pressure) of nasal fibroepithelial polyps.

ABSTRACT: Although endoscopic sinus surgery (ESS) is a standard procedure for adults and is considered a safe and effective procedure in children as well, some uncertainty remains when it comes to children, especially with regard to the future facial and sinus development. Overall, limited ESS does not affect sinus development, and extended ESS does not affect facial features. However, whether or not full-house ESS affects the sinus development, especially the frontal and sphenoid sinuses, remains unclear. The authors herein report a 15-year-old child who received full-house ESS and later re-examined the paranasal sinuses at 24âyears old, at which point the frontal and sphenoid sinuses had developed. This is the first report showing the development of the frontal and sphenoid sinuses after such a procedure.

Objectives: Disruption of the oxidative stress defense system is involved in developing various diseases. Sulfur compounds such as glutathione (GSH) and cysteine (CysSH) are representative antioxidants in the body. Recently, supersulfides, including reactive persulfide and polysulfide species, have gained attention as potent antioxidants regulating oxidative stress and redox signaling. However, their involvement in the pathogenesis of chronic rhinosinusitis (CRS) remains unclear. Methods: To clarify the changes in sulfur compounds within the sinus mucosa of each CRS subtype, we measured sulfur compound levels in the sinus mucosa of control individuals (n = 9), patients with eosinophilic CRS (ECRS) (n = 13), and those with non-ECRS (nECRS) (n = 11) who underwent sinus surgery using mass spectrometry. Results: GSH and CysSH levels were significantly reduced, and the glutathione disulfide (GSSG)/GSH ratio, an oxidative stress indicator, was increased in patients with ECRS. Despite the absence of notable variations in supersulfides, patients with ECRS and nECRS exhibited a significant reduction in glutathione trisulfide (GSSSG), which serves as the precursor for supersulfides. Conclusions: This study is the first quantitative assessment of supersulfides in normal and inflamed sinus mucosa, suggesting that sulfur compounds contribute to the pathogenesis of CRS. Level of Evidence: N/A.
RESUMEN
Introduction: Post-operative care after functional endoscopic sinus surgery (FESS) is essential for managing the long-term success of chronic rhinosinusitis. Post-operative sinus debridement promotes proper wound healing, but the procedure can be accompanied by discomfort and pain. Hence, we analysed the clinical factors related to sinus debridement time after FESS. Materials and Methods: We evaluated retrospectively the clinical factors affecting the time taken for post-operative sinus debridement on the first visit after the discharge. We reviewed 101 patients who underwent FESS at our hospital by the same surgeon and extracted patient information. The time for post-operative sinus debridement at the first outpatient clinic was measured. Results: The days of putting the cotton ball in the operated nostril were negatively associated with sinus debridement time (coefficient - -16.4 ± 5.7 seconds/day, P = 0.005). In contrast, current or history of asthma, amount of bleeding during the surgery, number of opened sinuses by the operation or the number of eosinophils in resected tissues under a microscope at ×400 was not associated. Discussion: We recommend the use of a cotton ball in the nostril after FESS because it shortens the sinus debridement time. Placing cotton balls in the nostril helps to maintain a humid wound environment and reduce crusting, leading to easier sinus debridement and better wound healing.
RESUMEN
The septochoanal polyp is one of the choanal polyps derived from the nasal septum. They rarely occur, with only a few cases reported in the English literature. The etiology is still uncertain though it is thought to be associated with inflammation. Pathological findings generally show chronic inflammatory polyps and should be differentiated from other tumors. We report a case of a 32-year-old man diagnosed with a septochoanal polyp on the concave side of the deviated nasal septum. Previous reports have not mentioned the relationship between septochoanal polyp and the direction of septal deviation. This case is a practical example when considering the potential causes of the septochoanal polyp.
RESUMEN
Actinomycosis is a bacterial infection caused by actinomyces. Although almost 50% of cases are related to the head and neck region, those in the nose and paranasal sinuses (PNS) are rare. Actinomycosis of the PNS is presumed to be typically caused by dental caries, dental manipulation, and maxillofacial trauma, which facilitate the penetration of oral pathogens into the sinus, and should thus be treated by the combination of surgical removal and potent antibiotics for at least two months. The current use of these antibiotics might be redundant, considering the nature of actinomycosis of the PNS, which does not invade the mucosal surface. We herein report a 67-year-old female treated with endoscopic sinus surgery (ESS) and diagnosed with actinomycosis of the PNS by pathological findings. She had no history of dental impairment or treatment. She was given routine perioperative prophylactic antibiotics (cefazolin) during the surgery, followed by low-dose clarithromycin. The mucosa of the PNS normalized without any discharge by three months after the operation. The patient is a valuable example that should prompt reconsideration of the commonly accepted pathogenesis and treatment of actinomycosis of the PNS.
RESUMEN
Rationale: Chronic maxillary atelectasis (CMA) is assumed to be caused by negative pressure in the maxillary sinus secondary to the obstruction of the ostiomeatal complex. Patient Concerns: A 49-year-old female patient first presented to our hospital complaining of right nasal congestion, rhinorrhoea and cheek pain. Diagnosis: Computed tomography (CT) accidentally revealed the inward bowing of the left maxillary sinus, which is a typical sign of CMA or silent sinus syndrome despite the maxillary ostium being potent. Treatment: We did not consider any intervention for CMA because she had no symptoms related to it. Outcomes and Take-Away Lessons: No progression was noted clinically or on CT at the 6-month follow-up. The pathogenesis of CMA in our patient was not explainable by the commonly accepted theory. Apparent hypertrophy of the left maxillary bone was confirmed on CT, thus osteitis with chronic rhinosinusitis might be the potential cause of CMA in the open maxillary sinus.
RESUMEN
Sinonasal inverted papilloma (IP) is the most common benign tumor in sinonasal cavities. Treatment involves excising the whole tumor, so it is essential to evaluate the extent of the tumor by preoperative radiographic findings. Magnetic resonance imaging (MRI) is superior to computed tomography (CT) for determining a tumor's location as MRI can discern the difference between mucus and IP. We herein report a 51-year-old man with sinonasal IP treated with endoscopic sinus surgery (ESS). Preoperative MRI showed findings resembling a convoluted cerebriform pattern on T2-weighted imaging, but this site was not enhanced by intravenous gadolinium at all. We preoperatively suspected that this site was not part of the tumor but rather the accumulation of mucus, and indeed, we found no tumor at this site when we performed the surgery. This patient is a valuable example of misleading findings of IP on T2-weighted imaging and underscores the importance of contrast-enhanced T1-weighted imaging to determine the extent of IP.
RESUMEN
BACKGROUND: Pneumonia is a common cause of illness and death of the elderly in Japan. Its prevalence is escalating globally with the aging of population. To describe the latest trends in pneumonia hospitalizations, especially aspiration pneumonia (AP) cases, we assessed the clinical records of pneumonia patients admitted to core acute care hospitals in Miyagi prefecture, Japan. METHODS: A retrospective multi-institutional joint research was conducted for hospitalized pneumonia patients aged ≥20 years from January 2019 to December 2019. Clinical data of patients were collected from the medical records of eight acute care hospitals. RESULTS: Out of the 1,800 patients included in this study, 79% of the hospitalized pneumonia patients were aged above 70 years. The most common age group was in the 80s. The ratio of AP to total pneumonia cases increased with age, and 692 out of 1,800 patients had AP. In univariate analysis, these patients had significantly older ages, lower body mass index (BMI), a lower ratio of normal diet intake and homestay before hospitalization, along with more AP recurrences and comorbidities. During hospitalization, AP patients had extended fasting periods, more swallowing assessments and interventions, longer hospitalization, and higher in-hospital mortality rate than non-AP patients. A total of 7% and 2% AP patients underwent video endoscopy and video fluorography respectively. In multivariate analysis, lower BMI, lower C-reactive protein, a lower ratio of homestay before hospitalization, a higher complication rate of cerebrovascular disease, dementia, and neuromuscular disease were noted as a characteristic of AP patients. Swallowing interventions were performed for 51% of the AP patients who had been hospitalized for more than two weeks. In univariate analysis, swallowing intervention improved in-hospital mortality. Lower AP recurrence before hospitalization and a lower ratio of homestay before hospitalization were indicated as characteristics of AP patients of the swallowing intervention group from multivariate analysis. Change in dietary pattern from normal to modified diet was observed more frequently in the swallowing intervention group. CONCLUSION: AP accounts for 38.4% of all pneumonia cases in acute care hospitals in Northern Japan. The use of swallowing evaluations and interventions, which may reduce the risk of dysphagia and may associate with lowering mortality in AP patients, is still not widespread.

Here we present a patient with a parotid secretory carcinoma (SC) with high-grade transformation. A 65-year-old female was referred to our hospital due to a gradually growing right parotid tumor discovered initially about 4 years earlier. MRI imaging detected a right parotid tumor 50 mm in the longer axis. Fine needle aspiration cytology indicated a class III tumor. Nine months after her initial visit, she revisited our department because of pain, trismus and facial paralysis. MRI detected a tumor 69 mm in the longer axis and 64 mm in the shorter axis and a biopsy specimen revealed parotid cancer. Furthermore, positron emission tomography revealed a synchronous small cell lung cancer (SCLC). Chemoradiotherapy for the SCLC was performed followed by an extended total parotidectomy for the parotid SC. Histological findings and ETV6-FISH analysis confirmed a parotid SC with high-grade transformation. Two months after the surgery, CT revealed a loco-regional recurrence and proton beam therapy (70.2 GyE/26 Fr) was performed. Three months after the proton beam therapy, CT indicated pleural effusion and lung metastasis, and fine needle aspiration cytology revealed the metastatic SC. Eight months after the surgery, the patient died due to the lung metastasis of SC.
