부비동은 얼굴에서 뼈 속에 존재하는 공기로 가득 찬 빈 공간이다. 그러나 부비동에 지속적으로 염증이 생기고 고름이 차면 축농증으로 발병하여 두통과 무기력증을 호소하고 음성의 변화를 가져온다. 따라서 본 논문에서는 외부 자극을 통해 부비동의 변화를 음성분석 요소로 측정하여 부비동 관련 질환을 예측하는 연구와 전두동, 사골동, 상악동, 접형동으로 구성된 부비동의 영역별 기능을 분석하는 연구를 수행하였다. 이를 위해 부비동 영역에 냉찜질 자극을 시행하고 자극 전과 후의 음성에 대한 포먼트주파수를 측정하여 상호간의 상관성 분석을 통해 외부 자극이 부비동에 미치는 영향을 분석하였다.

This report was to show the radiographic appearances of the fungus ball in a paranasal sinus and to emphasize the scan area of cone beam computed tomography (CBCT) to detect the calcification in the paranasal sinus. A seventyfour-year-old woman visited our department for the implant rehabilitation at both maxillary posterior edentulous region. Pre-operative radiographic examinations including the panoramic, CBCT, and multidector CT images were taken. An opacification in the right maxillary sinus was observed on the multiplanar image of CBCT, however the pre-determined scan area of CBCT in this report hardly showed the calcifications at the central portion of the maxillary sinus. The opacification in the maxillary sinus could be misdiagnosed as chronic maxillary sinusitis if the calcification of fungus ball was not simultaneously detected. The scan area of pre-operative CBCT needs to be enough to scan the paranasal sinus from top to bottom.

The false-positive FDG uptakes on head and neck areas are common due to benign lesion, iatrogenic and physiologic changes. The Schneiderian papilloma is uncommon benign tumor arising from the mucosa of the paranasal sinuses and nasal cavity. The findings of paranasal papilloma on conventional modality such as CT and MRI are non-specific and they could be confused with inflammatory polyp or retention cyst. Despite of benign tumor, the papilloma usually shows locally aggressive growth with malignant potential, therefore the FDG can be actively accumulated in this lesion. We describe the case of 18F-FDG PET/CT finding in a 77-year-old woman who demonstrates oncocytic papilloma in maxillary sinus.

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.

Objectives : To evaluate the anatomic variations of the paranasal sinuses on computed tomographs. Materials and Methods : The author examined the CT images of the paranasal sinuses retrospectively in 500 patients who visited Chonbuk National University Hospital between January 1996 and December 1997. Results : The highest incidence of anatomic variation of the paranasal sinuses in bilateral structures was agger nasi cel1(73.2％), followed by concha bullosa(31.1％), Onodi cell(24.0％), Haller ce1109.8％), maxillary sinus septum(3.0％), paradoxical middle turbinate(2.5％), pneumatized uncinate process(2.0％), and bent uncinate process. The highest incidence of anatomic variation in midline structures was nasal septum deviation(53.2％), followed by nasal septum aerated(29.4％), bulla galli(24.7％) asymmetric intersphenoid septum(22.3％), and nasal septum spur(13.8％). The correlation between anatomic variation and paranasal sinusitis was not found. Conclusions : The results of this study will aid in the diagnosis and treatment of paranasal sinus diseases, especially in the treatment planning before functional endoscopic surgery.

Objectives : The purpose of this study is to evaluate the computed tomographic (CT) images of the paranasal sinusitis(PNS). Materials and Methods : The author examined the extent and recurring patterns of the paranasal sinusitis and some important anatomic landmarks. The author analyzed PNS images retrospectively in 500 patients who visited Chonbuk National University Hospital between January 1996 and December 1997. Results : The most frequently affected sinus was maxillary sinus (82.9％), followed by anterior ethmoid sinus(67.9％), posterior ethmoid sinus(48.9％), frontal sinus(42.0％) and sphenoid sinus(41.4％). The characteristic features of CT images of the sinusitis were sinus opacification(22.4％), mucoperiosteal thickening(34.3％), and polyposis(2.0％). Sinonasal inflammatory diseases were categorized into 5 patterns according to Babber s classification. They were 1) infundibular(13.0％), 2) ostiomeatal unit(67.4％), 3) sphenoethmoidal recess (13.0％), 4) sinonasal polyposis (9.6％) and 5) unclassifiable patterns(18.0％). The incidences of contact between sinus and optic nerve were as follows ; the incidences of contact with posterior ethmoid sinus, sphenoid sinus. both posterior sinuses were 11.4％. 66.8％, 6.3％. respectively. The incidences of contact between sphenoid sinus and maxillary nerve, vidian nerve, internal carotid artery were 74.5％. 79.2％. 45.1％. respectively. The incidences of pneumatization of the posterior ethmoid sinus were as follows ; normal 70.6％ and overriding type 29.4％. The incidences of sphenoid sinus pneumatization were as follows; normal 56.9％ , rudimentary 12.5％, pterygoid recess 22.7％, anterior clinoid recess 2.7％, and both pterygoid and anterior clinoid recess type 5.2％. Conclusions : The inflammatory sinonasal diseases were classified into five patterns using the CT of PNS, which was proven to be an excellent imaging modality providing detailed information about mucosal abnormality, pathologic patterns, and the proximity of the important structures to the posterior paranasal sinuses. This result will aid in the interpretation of CT of PNS functionally and systemically.

Schwannomas are benign neurogenic tumors arising from the peripheral nerve sheath and rare in the nasal cavity and paranasal sinus. About 4% of schwannomas in the head and neck area arise in the sinonasal cavity. As unilateral nasal masses in the nasal cavity and paranasal sinus, schwannomas are likely to be mistaken for more common lesions such as nasal polyps or mucoceles. We recently experienced a case of schwannoma on the ethmoid sinus in a 33-year-old male which was surgically removed. Herein, we report this unusual case of schwannoma on the ethmoid sinus with a brief review of literature.

Aspergilloma of the paranasal sinus is a non-invasive form of aspergillosis, most often in the maxillary sinus. This case presents an 86-year-old female with aspergilloma of the left maxillary sinus. The patient's chief complaint was intermittent pain on the left maxillary first premolar area. A radiopacification of the left maxillary sinus was observed on the panoramic radiograph. Cone-beam computed tomography revealed complete radiopacification of the left maxillary sinus and scattered multiple radiopaque mass inside the lesion. Biopsy was performed under local anesthesia. On microscopic examination, numerous fungal hyphae, which branch at acute angle, were observed. The diagnosis was made as an aspergilloma based on the histopatholgic examination.

Cavernous sinus thrombosis not only presents with constitutional symptoms including fever, pain and swelling but also with specific findings such as proptosis, chemosis, periorbital swelling, and cranial nerve palsies. It is known to occur secondary to the spread of paranasal sinus infections in the nose, ethmoidal and sphenoidal sinuses. However, paranasal sinus infection of dental origin is rare. The following is a case of cavernous sinus thrombosis due to the spread of an abscess in the buccal and pterygomandibular spaces via buccal mucosal laceration.
