Subdural empyema is fulminating purulent infection that develops between the dura and the arachnoid membranes. It is rare but one of the most immediate of neurosurgical emergencies, hence the importance of proper diagnosis and early intervention. Most subdural empyema complicated in the ENT field originate from sinonasal or otologic infections rather than dental infections. In our case of 64-years-old male, who was admitted with headache and fever, the diagnosed subdural empyema originated from odontogenic parapharyngeal abscess. We report that the case was successfully managed after urgent surgical drainage by endoscopic transethmoidal approach with long term intravenous antibiotics.

Arteriovenous malformation is a vascular malformation with fast-flow shunt from the arteryto the vein. Extracranial arteriovenous malformation in the head and neck area is rare diseasecompared to other vascular malformations such as venous malformation or lymphatic malformation. Extracranial arteriovenous malformations especially on face can cause aesthetic problems,therefore surgeons should consider an importance of cosmetic outcome and choose appropriatetreatment plan. We report a case of 51-year-old male who presented with enlargednasal tip diagnosed arteriovenous malformation. This case showed successful outcome aftercombination therapy consisted of superselective embolization and surgical resection.

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. 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.

노양섭,최지은,이경은,정승규,홍상덕,김효열 대한이비인후과학회 2020 대한이비인후과학회지 두경부외과학 Vol.63 No.9

Background and Objectives One of the most common surgical procedures in children isadenoidectomy, but the causes of adenoid hypertrophy are not fully understood. Some studieshave found that allergies can be a risk factor for adenoid hypertrophy, asthma being one of theseallergic diseases. This study aimed to investigate the relationship between adenoid size andasthma in a group of children. Subjects and Method This study reviewed a total of 2063 pediatric patients with or withoutatopy and asthma who visited the Otorhinolaryngology and Pediatric unit at a tertiary medicalcenter from January 2011 to June 2016. We classified these patients into 4 groups according tothe presence of asthma or atopy and randomly selected 100 patients from each group (to a totalof 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 byCAP test and total IgE. Asthma was diagnosed according to the diagnosis criteria in the Koreanguideline 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 wasa negative correlation between adenoid size and atopic and asthmatic condition. Group 1 had asignificantly 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 nearlyidentical 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 findingmay be explained by a decrease in adenoid stimulation by nasal obstruction and a differencein the immune system, including allergic immune reactions. Further studies are needed.

Nasopharyngeal foreign bodies are rare and usually asymptomatic. Although there have been some reports about nasopharyngeal foreign body with sponges, inset or metallic bolt, there was no nasopharyngeal vegetable foreign body. We report a case of 56 year-old female patient with unusual nasopharyngeal foreign body (vegetable) presenting with postnasal drip. The foreign body was detected at right rosenmuller fossa in sinonasal computed tomography. After foreign body was removed by endoscopic endonasal approach, her postnasal drip was gone. In our knowledge, this is the first report about nasaopharyngeal foreign body with vegetable tissue.

Objectives. This study aimed to compare the outcome of endoscopic and microscopic tympanoplasty. Methods. This was a retrospective comparative study of 73 patients (35 males and 38 females) who underwent type I tympanoplasty at Samsung Medical Center from April to December 2014. The subjects were classified into two groups; endoscopic tympanoplasty (ET, n=25), microscopic tympanoplasty (MT, n=48). Demographic data, perforation size of tympanic membrane at preoperative state, pure tone audiometric results preoperatively and 3 months postoperatively, operation time, sequential postoperative pain scale (NRS-11), and graft success rate were evaluated. Results. The perforation size of the tympanic membrane in ET and MT group was 25.3%±11.7% and 20.1%±11.9%, respectively (P=0.074). Mean operation time of MT (88.9±28.5 minutes) was longer than that of the ET (68.2±22.1 minutes) with a statistical significance (P=0.002). External auditory canal (EAC) width was shorter in the ET group than in the MT group (P=0.011). However, EAC widening was not necessary in the ET group and was performed in 33.3% of patients in the MT group. Graft success rate in the ET and MT group were 100% and 95.8%, respectively; the values were not significantly different (P=0.304). Pre- and postoperative audiometric results including bone and air conduction thresholds and air-bone gap were not significantly different between the groups. In all groups, the postoperative air-bone gap was significantly improved compared to the preoperative air-bone gap. Immediate postoperative pain was similar between the groups. However, pain of 1 day after surgery was significantly less in the ET group. Conclusion. With endoscopic system, minimal invasive tympanoplasty can be possible with similar graft success rate and less pain.
