Background and Objectives : There were few literatures about the relationship between upper airway disorders and cardiovascular risk factors such as hypertension, although an association between impaired lower respiratory function and cardiovascular alterations was often reported. Our purpose was to assess the relationships between chronic sinusitis and hypertension. Materials and Methods : Three hundred subjects with bilateral chronic sinusitis who underwent functional endoscopic sinus surgery between 2015and 2017 were evaluated. Six hundred forty subjects without any nasal diseases were enrolled as a control group. Blood pressure and body mass index (BMI) were measured using a standardized method, and subjects were asked about current use of any antihypertensive medication, history of diabetes, smoking and alcohol drinking habits.Sinusitis group was assessed by nasal endoscopic examination, paranasal sinus CT scan and allergy test. Results : Average systolic and diastolic blood pressures were statistically significantly higher in subjects with sinusitis than control group. Chronic rhinosinusitis was associated with a 1.415-fold (95% confidence interval 1.053-1.930) increased hazard of hypertension after multivariate adjustment. Conclusions : These results suggest that sinusitis is associated with high blood pressure. Therefore patients with sinusitis may need special attention for blood pressure control. Further studies need to be performed to elucidate the pathogenesis behind such associations.

A 3-year-old Thoroughbred gelding was referred to the Jeju National University Equine Hospital with prolonged unilateral nasal discharge for several months. A sinus cyst was suspected based on the history, symptoms, endoscopic findings, and radiographic results. Computed tomography (CT) scan revealed that the cyst (7.5 × 8.0 × 10.0 cm) was located between the rostral maxillary sinus and the frontal sinus, causing distortion and remodeling of the overlying bones, swelling of the overlying cutaneous tissues, and a slight deviation of the nasal septum. Standing surgery under sedation was decided to remove the cyst. A frontonasal bone flap was performed using an oscillating bone saw, and the cyst filled with pus was removed. To support the approach to the maxillary sinus, trephination was performed. The horse was treated with sinus lavage via catheterization, nebulization, antibiotics, and nonsteroidal anti-inflammatory drugs. The horse was discharged 18 days after the surgery without signs of any complication. This case showed that a CT scan could be a valuable tool for the diagnosis and subsequent surgical management of paranasal sinus cysts in horses. Also, the frontonasal bone flap was useful for exposing and removing the large-sized of cyst in the paranasal sinus.

Neurofibroma is a neurogenic tumor arising from schwann cells or peripheral tissues of nerve sheaths. Neurofibroma rarely occurs as a solitary lesion but mostly occurs as part of neurofibromatosis and reports of neurofibromas developed in the nasal cavity or paranasal sinus are very rare. We report on a case of neurofibroma of the nasal cavity treated by endoscopic surgery. Preoperative computed tomography(CT), and punch biopsy suggested that the tumor was benign neurogenic tumor cofined to right nasal cavity. The tumor was removed with endoscopic surgery completely, and confirmed as neurofibroma by histological and immunohistochemical examination. We discuss the clinical and pathological characters of neurofibroma arising in the nasal septum.

A 4-year-old gelding Thoroughbred racehorse, which had been undergoing antibiotic therapy at a local veterinary clinic, was referred to the KRA veterinary center with a 20-day history of continuous right nasal discharge. Patient's history, endoscopic examination, and radiographic examination revealed primary maxillary sinusitis. Under sedation, surgical intervention was performed to collect samples and remove the accumulated mucopurulent exudate in the sinus. Swab samples were collected from the sinus during surgery for cytology and antimicrobial susceptibility testing. Only one type of bacteria was cultured, and molecular analyses of 16S ribosomal RNA gene sequences identified it as Staphylococcus aureus (S. aureus). The isolate was resistant to multiple antibiotics, which are frequently used in equine practice. Trimethoprim-sulfamethoxazole was chosen based on antibiotic susceptibility test, trephination, and sinus lavage using saline were applied to treat bacterial sinusitis. The clinical signs improved after 1 month and the patient resumed training. This report describes S. aureus isolated from bacterial maxillary sinusitis in a horse and its antibiotic susceptibility.

This case report describes our treatment of a persistent periantral abscess in a 35-year-old woman. The abscess developed following a zygoma-reduction surgery, during which a preexisting fungal ball had not been addressed. Our comprehensive treatment approach included functional endoscopic sinus surgery, fungal ball removal, abscess drainage, and debridement. Two weeks postoperatively, the patient's symptoms had resolved. A 6-month postoperative follow-up revealed no signs of recurrence or complications, and the patient reported satisfactory functional and aesthetic results. This case underscores the importance of thorough preoperative evaluations and raises awareness about the potential risks of untreated asymptomatic pathologies, which can potentially progress and lead to further complications.

A-50-year-old male patient presented with complaint of tenderness on the left malar area after traffic accident. Our first impression on him was zygomatic fracture, we did radiologic work-up and physical examination on him. But, on the computed tomography scan, there was no fracture or discontinuity on his facial bone. The computed tomography scan was revealed a 4-cm long foreign body in left maxillary sinus with a large amount of fluid collection. After thorough history taking from him, we reveal the patient had a history of trauma 30 years back on the left zygomatic area with a chopstick. The foreign body was removed via transoral approach with the endoscopic assist. There was no complication after operation.

Chronic maxillary atelectasis (CMA) is a progressive alteration in the volume of the maxillary sinuses that may result in facial asymmetry. CMA in asymptomatic patients is known as silent sinus syndrome (SSS) and is a rare entity, especially in pediatric patients. This study reports a case of SSS in a pediatric patient who received an early diagnosis through cone-beam computed tomography (CBCT). An asymptomatic 12-year-old female patient in orthodontic treatment presented with opacification of the left maxillary sinus on a panoramic radiograph. Clinically, the patient had discrete hypoglobus and enophthalmos. CBCT and nasal video-endoscopy revealed ostiomeatal obstruction with bone deformity, leading to diagnosis of SSS. Endonasal endoscopic maxillary sinusotomy was performed. Two years later, the patient remained asymptomatic, and a second CBCT exam confirmed a stable condition. This case highlights the role of optimal radiographic interpretation for early diagnosis of maxillofacial alterations in pediatric patients.

Myoepithelioma is a rare benign neoplasm that mostly arises in the major salivary glands and sometimes in the minor salivary glands, which account only for less than 1% of all salivary glands neoplasms. However, its extra-salivary involvement is even rarer and only a few cases of nasal cavity myoepithelioma were reported in the English-language literature so far. In this case report, we present a 40-year-old female with unilateral nasal obstruction diagnosed as myoepithelioma of the nasal septum and treated with endoscopic sinus surgery.

Purpose: The diagnosis of chronic rhinosinusitis requires a comprehensive knowledge of the signs and symptoms of the disease and an accurate radiographic assessment. Computed tomography (CT) is the superior imaging modality for diagnosis of chronic rhinosinusitis. However, considering the lower dose and higher resolution of cone-beam computed tomography (CBCT) compared to CT, this study aimed to assess the agreement between the findings of CBCT and functional endoscopic sinus surgery (FESS). Materials and Methods: This descriptive prospective study evaluated 49 patients with treatment-resistant chronic rhinosinusitis who were candidates for FESS. Preoperative CBCT scans were obtained before patients underwent FESS. The agreement between the CBCT findings and those of FESS was determined using the kappa correlation coefficient. The frequency of anatomical variations of the paranasal sinuses was also evaluated on CBCT scans. Results: Significant agreement existed between pathological findings on CBCT scans and those of FESS, such that the kappa correlation coefficient was 1 for mucosal thickening, 0.644 for nasal deviation, 0.750 for concha bullosa, 0.918 for nasal polyp, 0.935 for ostiomeatal complex (OMC) obstruction, and 0.552 for infundibulum thickening. Furthermore, 95.9% of patients had 1 or more and 79.6% had 2 or more anatomical variations, of which nasal deviation was the most common (67.3%). Conclusion: Considering the significant agreement between the findings of CBCT and FESS for the detection of pathological changes in the paranasal sinuses, CBCT can be used prior to FESS to detect chronic rhinosinusitis and to assess anatomical variations of the OMC.

We experienced a case of induction of general anesthesia without using neuromuscular blocking agents (NMBAs) in a 40-year-old woman with a history of anaphylaxis immediately after the administration of anesthetics lidocaine, propofol, and rocuronium to perform endoscopic sinus surgery 2 years before. The skin test showed a positive reaction to rocuronium and cis-atracurium. We induced general anesthesia without using NMBAs after inducing airway anesthesia with lidocaine (transtracheal injection and superior laryngeal nerve block). Deep general anesthesia was maintained with end-tidal 4 vol% sevoflurane. Hypotension was treated with phenylephrine infusion. The operation condition was excellent, and patient recovered without complications after surgery. Airway anesthesia with local anesthetics may be helpful when we cannot use NMBAs for any reason, including hypersensitivity to NMBA and surgery that needs neuromuscular monitoring.
