During paranasal sinus X-ray examinations in children, the radiological technologist's thyroid shield is often not implemented to shorten the examination time. This study measured the radiation exposure before and after the implementation of thyroid shielding by analyzing the difference in radiation exposure, the radiological technologist's could receive depending on the actual thyroid shielding. In the left TLD, when thyroid shielding was not performed(N), the radiation exposure dose(mSv) was 2.869 for the depth dose[Hp(10)] and 2.886 for the surface dose[H(3)], and when thyroid shielding was performed(Y), the Hp(10) was 0.033 and the H(3) was 0.034. In the right TLD, when thyroid shielding was not performed(N), the radiation exposure dose was 3.149 for Hp(10) and 3.137 for H(3), and when thyroid shielding was performed, the Hp(10) of (Y) was 0.013 and the H(3) was 0.015. The differences in the overall exposure dose measurement values are all statistically significant (p<0.05). The difference in radiation dose between when thyroid shielding was not performed and when thyroid shielding was performed was more than 99.2% in both cases, indicating a high radiation shielding rate.

Pneumosinus Dilatans consists of an abnormal dilatation of the paranasal sinuses which contain air only and lined by normal mucosa. It is a rare condition, the etiology of which is unclear. A 16 year old male complained frontal bossing which developed slowly. Simple X-ray and CT showed abnormal distension of frontal sinus. Another 19 year old male complained slowly growing left cheek mass. Simple X-ray and CT showed abnormal distension of anteromedial wall of maxillary sinus. In view of the cosmetic appearance, operations were performed. Distended sinuses walls were removed and reconstructed using $Medpore^{(R)}$. I report 2 cases of pneumosinus dilatans which developed in frontal and maxillary sinuses and the literature reviewed.

Aspergillosis of the maxillary sinus was rare disease, but it was increasing tendency with overuse antibiotics, streoid hormones, and anticanncerous agents. The clinical features and X-ray findings are similar to chronic suppurative paranasal sinusitis. Aspergillosis of the maxillary siuses may occur as a chronic diseae in an otherwise healthy person. This infection is usually confined to a single paranasal sinus, the maxillary antrum, though it can involve the orbit and may initiate with findings of proptosis and decreased vision. The disease is characterized by a wide range of initial symptoms, and should be considered as a possible diagnosis in sinusitis refractory to antibiotics and antral lavage. The choice of treatment of this disease is radical surgery and adjunctive systemic antifungal therapy. We experienced a case of right maxillary sinus aspergillosis in a 34 years old male who has dull pain on Rt. zygoma area, and a case of left maxillary sinus aspergillosis in a 30 years old male who had been suffered from nasal stiffness and frontal headache for 3-4 years. We reported two cases with review of literature.

Paranasal sinusitis, especially chronic is one of the most common diseases in the field of otolaryngology. It is similar to Bee Yeun(鼻淵) in oriental medicine. Most cases of sinusitis are due to anatomical abnormalities within ostiomeatal unit or disturbed mucocilliary flow. The ostiomeatal unit is the first place of contact with bacteria and allergens during aspiration, and it can be obstructed easily by minute mucosal swelling due to anatomical narrowness. Therefore the treatment of paranasal sinusitis is not easy and often leads to recurrences in spite of long term treatment or surgical therapy. We studied 83 patients who had visited our hospital with complaints of nasal symptoms; they had been diagnosed as having paranasal sinusitis through an endoscopy or CT scan in another hospital and were diagnosed as the paranasal sinusitis through a PNS series. The results were as follows: 1. Age and sex distribution: The most common occurence was found between 6-10 and 1-5 years old. The Males Were 52($62.7\%$) and Females were 31($37.3\%$). 2. By residence 58 cases lived in apts: 25 lived in houses. 3. The longest duration of disease varied from a lower of 13 to a higher of 36 months in 22 cases and from 7 to 12 months in 21 cases. 4. The most common complication & past history with otolaryngologic or allergic disease were adenoid or tonsil hypertrophy & tonsillectomy and adenoidectomy (21 cases). In decreasing order the others were atopic dematitis, otitis media with effusion and allergic rhinitis. 5. Distribution of paranasal sinus disease was most common in both maxillary sinuses in 52 cases. 12 cases showed a normal PNS X-ray series but these had been diagnosed as paranasal sinusitis with an endoscopy or CT scan in another hospital. 6. Common sinusitis - related symptoms were from highest incidence to lowest nasal obstruction, postnasal drip rhinorrhea, frontal headache, cough with sputum. 7. The most administered of prescription was Gamibangpoongtongsungsan and Sunbangpaedoksan extract. 8. In 26 cases the subjects showed significant improvement symptoms in PNS X-ray series : In 21 case showed partial improvement symptoms.

Purpose: An osteoma is one of the common benign tumors that penetrate the nasal portion, paranasal and frontal sinus. This tumor is mostly found by radiation test accidentally, however in rare cases; it can be found to be touched or with its symptoms as the tumor grows. We report this case since we found and healed the benign tumor which was affecting orbit and the both sides of fronal sinus. Methods: A 19 year old female patient visited to our hospital due to the mass on her forehead. The symptoms began 3 years ago but no special symptom was found except for touchable mass. She was diagnosed as the osteoma of superior orbital parts and both sides of frontal sinus using X-ray and CT scanning. The size of osteoma was $5{\times}2.5{\times}3.5\;cm$ and indicated the patterns penetrated to the right side of orbital region. The osteoma excision was conducted with coronal incision and wide area of defect part in frontal sinus and superior orbital part were reconstructed by cranial bone graft and resorbable fixation plates. Results: The patient recovered without any postoperative infections or complications and symptoms. Dysaesthesia was found on her frontal area but improved in 1 month after the surgery. Conclusion: The occurrences of osteoma in frontal sinus are rare and can be treated with conservative methods if there are no infections and symptoms. We report this case since we found the benign tumor, which was affecting orbit and the both sides of fronal sinus and healed it with coronal resectomy without any complications.

Esophageal manometry and Bernstein acid perfusion test were performed in 39 patients with globus sensation and 30 controls without experiencing a lump sensation in the throat. Globus patients also underwent physical examination, paranasal sinus x-ray, laryngoscopy and esophagogram. Nine of 39 patients were excluded from the study because local reasons for a lump sensation in the throat were found. Globus group showed significant elevation in upper esophageal sphinter pressure(P=0.0001) and six patients(20%) had evidence of nonspecific esophageal motility disorders, which suggested that hypertonicity of the upper esophageal sphinter and esophageal motility disorders could be the cause of globus syndrome.

Retrobulbar abscess is a rare, but severe complication of paranasal sinusitis. The clinical presentations are eyelid swelling, erythema, proptosis, conjunctival chemosis, restricted ocular movement, and decreased visual acuity. Diagnostic methods available for evaluating retrobulbar abscess include sinus X-ray, ultrasonography, computed tomography (CT), and bacterial culture. For the treatment of retrobulbar abscess, immediate surgical drainage and systemic antibiotic therapy are needed. Proper diagnosis and treatments are necessary for preventing visual loss, cavernous sinus thrombosis, subdural abscess, and other lifethreatening complications. A patient, a 30-year-old man, was admitted to our hospital because of progressive eyelid swelling, erythema, ptosis and decreased visual acuity on the right eye after endodontic treatment. The sinusitis occurred secondary to the infection from an upper molar tooth. The spread of the infection led to the orbit via ethmoidal sinus and posterior orbital wall. Immediate surgical intervention was performed and systemic antibiotics was administrated. The symptoms and signs are improved after treatments, so we present our case with a brief review of the literature.

소아의 폐쇄성 수면 무호흡 증후군은 편도 및 아데노이드 비대가 주된 원인이고, 편도 및 아데노이드 절제술 후 대부분 증세가 호전된다. 편도가 완전히 제거되지 않은 경우, 진단이 정확하지 않은 경우, 해부학적 기형이 동반되었을 때, 부비동염, 알레르기 비염 등의 만성 염증이 있는 경우, 비만이 있거나, 어린 나이에 발병한 경우 등에는 편도 및 아데노이드 절제술 후에도 폐쇄성 수면 무호흡 증후군이 재발할 수 있다. 11세 비만한 남아가 수년 전부터 심한 코골이가 있어서 병원을 방문하였다. 복부 초음파에서 지방간 소견을 보였으며 본원에서 시행한 수면다원검사상 무호흡저호흡지수(apneahypopnea index：AHI)가 70.5로 심한 OSAS 진단 받은 후 편도 및 아데노이드 절제술을 시행하였다. 수술 4개월 후 시행한 수면다원검사상에서는 AHI가 0으로 완전히 회복 되었다. 수술 1년 후 코골이와 코막힘을 다시 호소하여 소아과를 방문하였는데, 수면다원검사상 AHI 43으로 폐쇄성 수면 무호흡 증후군이 중증으로 재발된 소견을 보였다. 환아 진찰 소견상 부비동염이 심하여 항생제, 국소 스테로이드 분무, 항류코트리엔제제 치료를 시작하였고 3개월의 치료 후에 부비동염과 주관적인 증상이 호전되었다. 다시 시행한 수면다원검사에서 AHI는 8.5로 감소하였다. 당시 시행한 복부초음파상 지방간 소견은 보이지 않고 비만도도 정상화되었다. 이러한 증례로 보아 만약 폐쇄성 수면 무호흡 증후군 소아에서 수술을 시행한 후에도 증세가 지속되거나 재발한다면 지속된다면 재발을 의심하고 반드시 수면다원검사를 추적 검사하는 것이 권장되며 여러 위험인자를 고려하여 치료계획을 빨리 세우면 합병증을 예방할 수 있을 것이다.
