Sinonasal undifferentiated carcinoma (SNUC) is an extremely rare, highly aggressive malignancy of the nasal cavity and paranasal sinuses. Patients with SNUC usually being asymptomatic until the tumor has extensively progressed therefore frequently present with invasion of the orbit or cranial vault. Most case series of SNUC report very poor prognosis despite aggressive multimodality therapy. We recently experienced a 78-year-old male patient diagnosed as SNUC occurred from the left sphenoid sinus with invasion to the cavernous sinus and orbital content, which was treated intranasal endoscopic debulking surgery combined with curative radiation therapy successfully, and report this case with a review of literature.

The authors report a case of cholesterol granuloma in the sphoid sinus in 54-year old woman, which is probably the first report of cholesterol granuloma arising primarily in the sphenoid sinus apart from the petrous bone. The initial clinical presentations were unilateral decreased visual acuity and facial sensory change. The mass was removed totally via transsphenoidal route and the pathological examination revealed cholesterol clefts and chronic granulomatous changes. The differences between the present case and the previous reports are discussed.

Synovial sarcomas are rare soft tissue malignancies arising from tendons, tendon sheaths, and bursal structures. These tumors usually develop in the extremities of adolescents and young adults. Uncommonly, these tumors may arise in the head and neck approximately 9% of all synovial sarcomas. Most common sites of head and neck synovial sarcomas are hypopharynx and surrounding structures of paranasal sinuses. However, frontal bone without involving paranasal sinus is extremely rare. We report a case of biphasic synovial sarcoma of the frontal bone discuss the clinical and pathologic features of this case with the literature review.

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.

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.

Cholesterol granuloma is a disease in which cholesterol crystals act as a foreign substance in the surrounding tissues and cause granulomatous reaction and fibrosis within the chamber. It is found in various locations of the body, but the most common location is the temporal bone associated with middle ear disease. Because the disease is associated with breathing disturbance, it may also occur in the paranasal sinus. However, it has been rarely reported since its first report by Graham and Michaels in 1978. Recently, we experienced a case of cholesterol granuloma of the right maxillary sinus of a 63-year-old female patient without any nasal symptoms. We successfully managed this case with Caldwell-Luc operation. Also, we summarized the cases of cholesterol granuloma of the sinonasal region reported in Korea.

Leiomyosarcoma(LMS) is a malignant neoplasm of smooth muscle origin, which accounts for 7 % of all soft tissue sarcomas. The most common sites are the gastrointestinal tract and female genital tract. In contrast, primary LMS of the oral and maxillofacial area is rare due to the paucity of smooth muscle in this region. Especially, LMS of the paranasal sinuses is very rare and has an aggressive clinical behavior. Only 28 cases have been described in the english literature, and of these, only 3 patients treated with surgery had a disease-free survival. A 46-year-old woman came to our department for the evaluation of pain on right midface. After a diagnostic work-up, the lesion was diagnosed as LMS of the right maxillary sinus. The radical surgery was done and chemotherapy combined radiotherapy was followed from post operation 1 month. The patient was disease free at post-operation 1 year. We will report this case with literature review.

A mucocele is an epithelium-lined, mucus-filled cavity in the paranasal sinuses. Mucocele may develop due to scarring and obstruction of the sinus ostium caused by midface sinus trauma, such as orbital bone fracture or endoscopic sinus surgery. The authors report two cases of orbital mucocele as complications following midface sinus injury (endoscopic sinus surgery in one case, and orbital fracture repair in the other). In both cases, imaging studies showed a large orbital mucocele accompanied by bony erosion and orbital wall remodeling, compressing the ocular muscle. Using an open approach, the lesion was excised and marsupialized. The symptoms resolved, and the postoperative eyeball position was normal. Orbital mucocele may cause serious complications such as ocular symptoms, orbital cellulitis, osteomyelitis, and the formation of an abscess with the potential to invade the brain. Therefore, surgeons should consider the possibility of mucocele as a late complication of surgery and initiate an immediate work-up and surgical treatment if needed.

Mucocele of the paranasal sinuses is a benign, slow-growing, expansile lesion. Maxillary sinus mucoceles are usually associated with painless bulging of the cheek; however, orbital expansion is rarely observed. Maxillary sinus mucoceles can be classified as primary or secondary according to their etiology. An impediment to sinus ostium ventilation is thought to be the cause of primary mucocele, while sequestering of residual mucosa after surgery in the wound and long-term retention of tissue fluid have been suggested to lead to the formation of secondary mucocele. This report presents 2 cases of primary and secondary mucoceles, with a focus on radiographic features. As primary and superiorly positioned secondary maxillary sinus mucoceles are uncommon and their close proximity to the orbit predisposes the patient to significant morbidity, the authors expect that this report will contribute to a better understanding and diagnosis of maxillary sinus mucocele involving the orbit.
