RESUMEN
Objectives@#. Fibro-osseous lesions of the paranasal sinuses can present various clinical manifestations. This study aimed to report the long-term clinical course of benign fibro-osseous lesions (BFOLs) in the paranasal sinuses, including clinical and radiologic features. @*Methods@#. Radiologically confirmed BFOLs between 1994 and 2016, with the exclusion of osteoma cases, were retrospectively reviewed. We compared demographic characteristics between the surgery and observation groups. The reasons for the imaging study, radiographic features, histopathology, and clinical course based on serial image scans were analyzed. @*Results@#. In total, 183 subjects were selected from a thorough review of head and neck radiologic tests (n=606,068) at a tertiary referral hospital over 22 years. Patients’ mean age was 28.6±18.1 years, and 56.3% were males. A diagnostic imaging workup was performed in 55.7% of patients due to facial asymmetry, headache, skull mass, or other symptoms related to BFOLs. In other patients (37.7%), BFOLs were found incidentally on computed tomography or magnetic resonance imaging. The most common diagnosis was fibrous dysplasia, followed by ossifying fibroma, based on both radiologic exams and histopathologic results. In total, 42.6% of the patients underwent surgery because of subjective symptoms or esthetic concerns. The patients who underwent surgery were younger (P<0.001) and had a longer follow-up duration (P<0.001) than those who underwent observation. Patients who experienced lesion growth (11.5%) were younger (P<0.001) and had more lesion sites (P=0.018) than those who did not, regardless of surgical treatment. Five patients underwent optic nerve decompression, and one patient experienced malignant transformation. @*Conclusion@#. BFOL in the paranasal sinuses is a rare disease, and most cases were observed without specific treatment. Surgical treatment should be considered in symptomatic patients with aggressive clinical features. Regular observation and management are needed, particularly in younger patients in their teens.
RESUMEN
Objectives@#. Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant vascular disorder characterized by recurrent epistaxis, telangiectasia, and visceral arteriovenous malformations (AVMs). Activin A receptor-like type 1 (ACVRL1/ALK1) and endoglin (ENG) are the principal genes whose mutations cause HHT. No multicenter study has yet investigated correlations between genetic variations and clinical outcomes in Korean HHT patients. @*Methods@#. Seventy-two members from 40 families suspected to have HHT based on symptoms were genetically screened for pathogenic variants of ACVRL1 and ENG. Patients with genetically diagnosed HHT were also evaluated. @*Results@#. In the HHT genetic screening, 42 patients from 24 of the 40 families had genetic variants that met the pathogenic criteria (pathogenic very strong, pathogenic strong, pathogenic moderate, or pathogenic supporting) based on the American College of Medical Genetics and Genomics Standards and Guidelines for either ENG or ACVRL1: 26 from 12 families (50%) for ENG, and 16 from 12 families (50%) for ACVRL1. Diagnostic screening of 42 genetically positive HHT patients based on the Curaçao criteria revealed that 24 patients (57%) were classified as having definite HHT, 17 (41%) as having probable HHT, and 1 (2%) as unlikely to have HHT. Epistaxis was the most common clinical presentation (38/42, 90%), followed by visceral AVMs (24/42, 57%) and telangiectasia (21/42, 50%). Five patients (12%) did not have a family history of HHT clinical symptoms. @*Conclusion@#. Only approximately half of patients with ACVRL1 or ENG genetic variants could be clinically diagnosed as having definite HHT, suggesting that genetic screening is important to confirm the diagnosis.
RESUMEN
Endoscopic sinus surgery is a treatment method for chronic rhinosinusitis not controlled with medical treatment. It had started with functional endoscopic sinus surgery and the concept of reboot approach was introduced recently. For safe surgical treatment, understanding the anatomy especially personal variations between well-known structures is important. The practical points of surgical concept during endoscopic sinus surgery was suggested.
RESUMEN
Osseous hemangioma typically occurs in the vertebral column or skull bones. It it is extremely rare in the nasal bone. Only nine cases originating in the turbinate and maxillary bone have been reported in the English and Korean literature. Herein, we present the case of a 51-year-old women with a dorsum mass to share our experience with intraosseous hemangioma successfully removed and reconstructed by an endonasal approach.
RESUMEN
Foreign bodies in the sinus are rare entities that are often associated with trauma. This paper presents a case of a metallic foreign body that was retained without any symptoms for over 40 years. A skull X-ray and computed tomography scans showed blades of scissors inside the maxillary sinus, extending to the middle meatus without affecting vital structures. The foreign body was successfully removed by an endoscopic approach. There were no complications during and after the surgery. The presence of retained foreign bodies in the maxillofacial region is rarely discussed in previous publications. This manuscript focuses on the asymptomatic period of this foreign body and aims to discuss the necessity and feasibility of a wait-and-see approach in selected cases.
RESUMEN
Background and Objectives@#Chronic rhinosinusitis with nasal polyps (CRSwNP) recurs frequently after endoscopic sinus surgery (ESS). The aim of study was to evaluate the efficacy of triamcinolone-soaked absorbable gelatin foam (gelfoam) as a treatment for recurred polypoid changes after ESS.Subjects and Method: A total of 35 patients and 57 nasal cavities was retrospectively reviewed. All patients underwent triamcinolone- infused gelfoam packing for 1 week under nasal endoscopic guidance. Endoscopic scores were evaluated at 1 week, 1 month, and 3 months. We analyzed clinical characteristics between success and failure groups. @*Results@#Endoscopic scores were significantly improved after triamcinolone-soaked gelfoam packing, and the effects were maintained at 3-month follow-up (1.85±0.61 vs. 0.82±0.77, p<0.001). Duration between surgery and gelfoam packing was shorter in the success group compared to the failure group (8.2±6.9 vs. 13.7±8.4 weeks, p=0.033). Serum eosinophil cationic protein and tissue eosinophil counts were significantly higher in the failure group (p=0.025 and p=0.010, respectively). @*Conclusion@#Triamcinolone-soaked gelfoam packing is an effective and safe method for managing recurrent polypoid change in patients with CRSwNP after ESS. Early intervention contributed to a successful result, and eosinophilic inflammation was associated with poor outcomes.
RESUMEN
Background and Objectives@#One of the most common surgical procedures in children is adenoidectomy, but the causes of adenoid hypertrophy are not fully understood. Some studies have found that allergies can be a risk factor for adenoid hypertrophy, asthma being one of these allergic diseases. This study aimed to investigate the relationship between adenoid size and asthma in a group of children.Subjects and Method This study reviewed a total of 2063 pediatric patients with or without atopy and asthma who visited the Otorhinolaryngology and Pediatric unit at a tertiary medical center from January 2011 to June 2016. We classified these patients into 4 groups according to the presence of asthma or atopy and randomly selected 100 patients from each group (to a total of 400 pts): group 1 (asthma-, atopy-); group 2 (asthma-, atopy+); group 3 (asthma+, atopy-) and group 4 (asthma+, atopy+). The presence of allergic sensitization (atopy) was evaluated by CAP test and total IgE. Asthma was diagnosed according to the diagnosis criteria in the Korean guideline for asthma. Adenoid size was evaluated with the adenoidal-nasopharyngeal ratio (A/N ratio) by the adenoid view. @*Results@#The four groups did not differ from each other significantly in age or sex. There was a negative correlation between adenoid size and atopic and asthmatic condition. Group 1 had a significantly larger A/N ratio than the other groups (group 1=0.534±0.138; group 2=0.469± 0.140; group 3=0.476±0.135; group 4=0.482±0.128, p<0.05). However, group 4 showed nearly identical results to groups 2 and 3, despite the combination of asthma and atopy in group 4. @*Conclusion@#Large adenoids were negatively associated with atopy and asthma. This finding may be explained by a decrease in adenoid stimulation by nasal obstruction and a difference in the immune system, including allergic immune reactions. Further studies are needed.
RESUMEN
Objectives@#. Endoscopic pituitary surgery usually requires a collaboration between neurosurgeons and ENT surgeons to achieve optimal outcomes. However, neurosurgeons occasionally perform these procedures alone without an ENT surgeon. In this study, postoperative sinonasal quality of life and olfactory function were compared in patients who underwent endoscopic pituitary surgery performed by a single neurosurgeon or by a collaborative team of a neurosurgeon and an ENT surgeon. @*Materials and Methods@#. A retrospective review of prospectively collected data was performed. Patients who underwent endoscopic pituitary surgery for pituitary adenoma from January 2015 to April 2018 were included. The study patients were divided into two groups; patients in group 1 underwent surgery performed by a single neurosurgeon, while patients in group 2 received surgery performed by a collaborative team of surgeons. Olfaction was assessed using a subjective Likert scale, the Cross-Cultural Smell Identification Test (CC-SIT), and the butanol threshold test (BTT). In addition, patients answered the Sino-nasal Outcome Test (SNOT-22) questionnaire regarding sinonasal quality of life before and 3 months after surgery. @*Results@#. This study included 152 patients (46 patients in group 1 and 106 patients in group 2). Significant differences were not observed between the two groups regarding age, sex, tumor size, or operation time. Although subjective olfaction was not significantly different before and after surgery, group 2 showed significantly better objective olfactory function based on the CC-SIT (8.44±3.00 vs. 9.84±1.40; P=0.012) and BTT (4.67±0.84 vs. 5.02±0.33; P=0.022) scores at 3 months after surgery. The SNOT-22 scores were not statistically significantly different between the two groups (P>0.05). @*Conclusion@#. In the present study, better olfactory outcomes were observed in patients who underwent surgery performed by a collaborative team of a neurosurgeon and an ENT surgeon. This result shows the need for collaboration between neurosurgeons and ENT surgeons in endoscopic pituitary surgery.
RESUMEN
OBJECTIVES: Endoscopic prelacrimal medial maxillectomy (EPMM) was previously reported to treat maxillary inverted papilloma. This study aimed to compare prelacrimal recess approach with the conventional Caldwell-Luc approach (CLA) to remove benign maxillary sinus tumors and to evaluate the usefulness of this approach based on our experience. METHODS: Ten patients who underwent EPMM at our hospital from January 2013 to December 2017 were reviewed. We also reviewed 30 patients who underwent benign maxillary sinus tumor resection via CLA during the same period. From medical records, postoperative pathological results, complications due to surgery, and recurrence rate were evaluated. RESULTS: There were eight inverted papilloma, one ameloblastoma, and one ossifying fibroma in the EPMM group. In the CLA group, all 30 cases were inverted papilloma. There were no cases of failure at gross total removal during surgery, and no recurrences were observed during follow-up in either groups. Mean follow-up period was 13.0 months in CLA group and 10.8 months in EPMM group. Regarding postoperative complications, 11 patients of the CLA group (37%) and three patients of the EPMM group (30%) had numbness around the cheek and upper lip area after surgery (P=0.715). In the CLA group, there were eight patients who had numbness lasting more than 3 months after surgery, and two patients had numbness for more than 1 year. However, facial numbness disappeared within 3 months in all patients in the EPMM group, in which epiphora was not observed. CONCLUSION: EPMM is the effective surgical approach for resecting benign maxillary sinus tumor compared with CLA. Although facial numbness was reported in EPMM, the duration of numbness was shorter than CLA.

PURPOSE: Despite medical and surgical treatments, some cases of nasal polyps (NP) exhibit recidivism. However, the endotype of refractory chronic rhinosinusitis with NP (CRSwNP) remains unclear. Therefore, the objective of this study was to characterize the immunological profile of refractory CRSwNP. METHODS: The control (n =23), primary NP group (pNP, n =70) and refractory NP group (rNP, n =86) were enrolled in this study. Patients who underwent revision surgeries due to failed maximal medical treatment after primary surgery were defined as the rNP group. A total of 18 inflammatory markers were investigated in nasal tissues using multiplex cytokine assay or enzyme-linked immunosorbent assay. RESULTS: The clinical characteristics of rNP included more extensive disease and worse clinical course after surgery. Additionally, rNP subjects showed higher infection rate (mucopurulence and culture-positive rate), more frequent use of antibiotics and suffered from symptomatic bacterial infection, increased asthma morbidity compared to pNP. Cytokine profile analysis showed that levels of Th17-associated mediators (myeloperoxidase, interleukin (IL)-8, IL-17A and IL-23), B-cell activating factor (BAFF) and Th1 cytokine (interferon-γ) were up-regulated in rNP compared to controls and pNP. Human neutrophil elastase-positive cells were also enhanced in rNP compared with pNP. Upregulation of Th17/Th1mediators and BAFF were observed in rNP, regardless of tissue eosinophilia or asthmatic comorbidity. Interestingly, eosinophilic markers, such as eosinophil cationic protein and C-C motif chemokine ligand 24, were up-regulated in asthmatic rNP compared to pNP and controls. Levels of anti-dsDNA immunoglobulin (Ig) G and IgA were up-regulated in rNP and highest in asthmatic eosinophilic rNP among subtypes of rNP. CONCLUSIONS: Our results suggest that Th17/Th1-associated mediators and BAFF may play a role and be a potential therapeutic target in refractory CRSwNP. Additionally, eosinophilic markers and autoantibodies may contribute to refractoriness in asthmatic rNP.

BACKGROUND AND OBJECTIVES: To investigate the common site of recurrent epistaxis after initial intervention such as packing and cauterization had failed and to evaluate the efficacy of surgical endoscopic electrocautery. SUBJECTS AND METHOD: Retrospective review of 47 patients with recurrent and uncontrolled idiopathic epistaxis between October 1995 and March 2016. All patients underwent endoscopic examination in the operating room after hospitalization. We performed electrocautery when a bleeding site was found. RESULTS: The most common sites of bleeding were the inferior meatus (28%), sphenoethmoid recess (23%), superior septum around the olfactory cleft (13%), and the posterior end of the middle turbinate (15%). There was no serious complication during the one week after surgery. In 46 (98%) patients, refractory epistaxis was successfully controlled. One patient had recurrent epistaxis after electrocautery and underwent endoscopic sphenopalatine artery ligation. CONCLUSION: In patients with refractory idiopathic epistaxis after failure of first-line treatment, endoscopic examination through a surgical approach and electrocautery for suspected bleeding are effective.

OBJECTIVES: Middle vault deviation has a significant effect on the aesthetic and functional aspects of the nose, and its management continues to be a challenge. Spreader graft and its modification techniques have been focused, but there has been scarce consideration for removing surplus portion and balancing the upper lateral cartilage (ULC). This study aimed to report the newly invented triangular-shaped resection technique (“triangular resection”) of the ULC and to evaluate its efficacy for correcting middle vault deviation. METHODS: A retrospective study included 17 consecutive patients who presented with middle vault deviation and underwent septorhinoplasty by using triangular resection at a tertiary academic hospital from February 2014 and March 2016. Their outcomes were evaluated pre- and postoperatively including medical photographs, acoustic rhinometry and subjective nasal obstruction using a 7-point Likert scale. RESULTS: The immediate outcomes were evaluated around 1 month after surgery, and long-term outcomes were available in 12 patients; the mean follow-up period was 9.1 months. Nasal tip deviation angle was reduced from 5.66° to 2.37° immediately (P < 0.001). Middle vault deviation also improved from 169.50° to 177.24° (P < 0.001). Long-term results were 2.49° (P=0.015) for nasal tip deviation and 178.68° (P=0.002) for middle vault deviation. The aesthetic outcome involved a complete correction in eight patients (47.1%), a minimally visible deviation in seven patients (41.2%) and a remaining residual deviation in two patients (11.8%). Pre- and postoperative minimal cross-sectional areas (summation of the right and left sides) were 0.86 and 1.07, respectively (P=0.021). Fifteen patients answered about their nasal obstruction symptoms and the median symptom score had alleviated from 6.0 to 3.0 (P=0.004). CONCLUSION: Triangular resection of the ULC is a simple and effective method for correcting middle vault deviation and balancing the ULCs without complications as internal nasal valve narrowing.

Retention cyst of the maxillary sinus is a benign lesion produced from obstruction of a seromucous gland or duct. It is mostly asymptomatic but sometimes is accompanied by facial pain, headache, nasal obstruction, and other symptoms. However, there are some debates on whether the symptoms are directly related with retention cyst. These cysts typically do not require treatment. However, when accompanied by symptoms, treatment can be administered for diagnostic and therapeutic purposes. We report a case in which facial pain is caused by a maxillary retention cyst suspended from an infraorbital nerve.

OBJECTIVES: This study evaluated whether the symptoms of laryngopharyngeal reflux (LPR) change after multilevel surgery for obstructive sleep apnea (OSA). METHODS: Patients who underwent multilevel surgery for OSA between April 2009 and September 2014 were enrolled in this study. All patients underwent preoperative polysomnography prior to surgery and were asked to complete the reflux symptom index (RSI) questionnaire before and after surgery. RESULTS: Of 73 enrolled patients, 24 (33%) reported an RSI score >13 and were thus classified as having reflux. The mean RSI score before surgery was 11.48±7.95; this number decreased to 4.95±6.19 after surgery (P < 0.001). The rate of positive RSI responses was 33% before surgery and 9% after surgery. Each variable that comprised the RSI improved significantly after surgery, except for difficulty with swallowing. Regarding the degree of RSI improvement after surgery, there were no significant differences between subgroups according to sex, age, body mass index, OSA severity, or surgical outcome. CONCLUSION: LPR symptoms are prevalent in OSA patients. Treatment for OSA using multilevel surgery potentially reduces the symptoms of LPR.

BACKGROUND AND OBJECTIVES: Skull base osteomyelitis (SBO) typically evolves as a complication of malignant otitis externa (MOE) in diabetic patients and involves the temporal bone. Central SBO (CSBO), which mainly involves the sphenoid or occipital bones, has clinicaland radiological characteristics similar to those of SBO but without coexisting MOE. We investigated a group of patients with CSBO and studied the clinical course of CSBO. SUBJECTS AND METHOD: Medical records of patients who were diagnosed with CSBO were retrospectively analyzed from 1999 to 2014. RESULTS: Ten patients (mean age; 60.5 years) were identified. There were five males and five females. All patients suffered from headache, and six patients had cranial nerve palsy including oculomotor (20%), abducens (10%), vestibulocochlear (10%), glossopharyngeal (20%), vagus (30%) and hypoglossal (10%) nerve. Patients had underlying diseases including diabetes mellitus (40%), immunosuppression status after liver transplantation (10%) and cardiovascular disease (40%). Four patients received endoscopic biopsy and debridement for diagnostic and curative intent. Patients were treated with intravenous antibiotics for 5.1 weeks in average and oral antibiotics for 17 weeks. Mean follow-up period was 12.4 months and the mortality rate was zero. 40% of patients had residual neurologic deficit. The earliest sign of improving CSBO was headache (mean; 3.1 weeks) and the erythrocyte sedimentation rate was the latest improving sign (mean; 4 months). CONCLUSION: CSBO was diagnostic and therapeutic challenge to the clinicians. The timely diagnosis and long-term antibiotics therapy could avoid a mortality case and minimize the permanent neurologic deficit.

OBJECTIVES: Compliance with continuous positive airway pressure (CPAP) treatment remains a primary concern for improving treatment outcomes of obstructive sleep apnea. There are few studies that have considered the role of upper airway anatomy on the compliance with CPAP. We hypothesized that upper airway anatomy would influence the compliance with CPAP. METHODS: One hundred out of 161 consecutive patients were enrolled in this study. The following possible determinants were tested against CPAP use: demographic and anthropometric data, minimal cross-sectional area on acoustic rhinometry, cephalometric and polysomnographic data, questionnaires of Epworth sleepiness scale and Beck depression index, and histories of previous upper airway surgery, degree of nasal obstruction, daily cigarette consumption, and weekly frequency of alcohol intake. RESULTS: Univariate analysis showed that histories of previous upper airway surgery and less frequent alcohol consumption, and longer mandibular plane-hyoid length (MP-H) on cephalometry were associated with longer average daily CPAP use. After adjustment for the confounding factors with multiple linear regression analysis, alcohol consumption and MP-H were still associated with the compliance with CPAP significantly. CONCLUSION: To improve compliance with CPAP, careful evaluations of upper airway problems and life style are important before initiating CPAP.

BACKGROUND AND OBJECTIVES: Obstructive sleep apnea syndrome(OSAS) is characterized by repeated apnea, hypopnea, and micro-arousals during sleep. Among various treatment modalities of OSAS, continuous positive airway pressure(CPAP) treatment is the most effective and successful. The aim of this study was to compare efficacy and safety of newly developed Korean CPAP with standard CPAP in OSAS patients. MATERIALS AND METHOD: In total, 20 of 26 recruited OSAS patients completed the study. All subjects first used the standard CPAP for 4 weeks. After an at least 2 week wash-out period, the subjects used the newly developed CPAP for 4 weeks. Polysomnography, questionnaires associated with sleep, lipid profile, pulmonary function test, cardiac marker, and physical examinations were evaluated at baseline and were followed-up after each treatment. RESULTS: After treatment with the newly developed CPAP, the apnea-hypopnea index was decreased from 53.2/hr to 2.5/hr and was equivalent to that of the standard CPAP. Most of the changes in questionnaire scores, laboratory findings, and physical examinations after newly developed CPAP treatment were equivalent to those with standard CPAP. No serious adverse events were observed during the study. CONCLUSION: The efficacy and safety of a newly developed CPAP are equivalent to those of standard CPAP in OSAS patients.

RESUMEN
BACKGROUND: Obstructive sleep apnea (OSA) is characterized by repeated apnea, hypopnea, and micro-arousals during sleep. Many studies have described correlations between OSA and multiple systemic diseases, such as cardiovascular, cerebrovascular, and metabolic diseases. The aim of this study was to determine whether the compliance of continuous positive airway pressure (CPAP) affects the short-term systemic responses in OSA patients. METHODS: Twenty-four newly diagnosed OSA patients were enrolled. All subjects used CPAP for 4 weeks. The subjects were divided into two groups according to the rate of using CPAP over 4 hours per night. Complete blood cell count, coagulation results, blood chemistry, lipid profiles, and pulmonary function results were evaluated at baseline, and were followed up after 4 weeks. RESULTS: After CPAP treatment, WBC count, hemoglobin, hematocrit, albumin, AST, ALT, Cl, and peak expiratory flow rate (PEFR) were significantly changed in the higher compliance group (n=14), whereas platelet count and triglyceride levels were significantly changed in the lower compliance group (n=10). In multivariate analysis, the changes in WBC count, hemoglobin and hematocrit were statistically significant between the higher compliance and lower compliance groups (p=0.0056, 0.0016, and 0.0051). CONCLUSION: The compliance of CPAP affects the short-term systemic responses in OSA patient.

BACKGROUND: Nasopalatine duct cysts (NPDCs) are considered the most common non odontogenic cysts of the maxilla. Although the recommended treatment is complete removal of the lesion, complications, such as hematoma or fistula, can occur, especially in extensive cases. The aim of the present paper was to introduce transnasal endoscopic marsupialization as an efficient and useful treatment for NPDC. MATERIALS AND METHODS: A retrospective review of 5 patients with extensive NPDCs (>2 cm) protruding into their nasal cavities was performed. All patients underwent endoscopic endonasal marsupialization. In order to survey the long-term, subjective outcomes, telephone interviews were conducted. RESULTS: The mean age of the included patients with NPDC was 32 years and all were male. Most of the patients had facial pain (100%) and nasal obstruction (80%), and somepatients complained of palate swelling (60%). There were no perioperative complications. The mean OPD follow-up duration was 3.7 months and a telephone survey was conducted with 4 patients at a mean of 27.5 postoperative months. Patients complained of some crust formation in the nasal cavity, but no cyst relapse or other significant complications were reported. CONCLUSIONS: A large NPDC protruding into the nasal cavity can be easily and efficiently managed with endoscopic endonasal marsupialization as a substitute for complete enucleation.
