  • 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.

  • Purpose: This study aimed to assess incidental abnormal findings in the paranasal sinuses and anatomical variations of the ostiomeatal complex (OMC) on magnetic resonance imaging (MRI) scans. Materials and Methods: MRI scans of 616 patients (mean age, 44.0±19.4 years) were evaluated. Prior to obtaining the MRI scans, a checklist of patients' clinical symptoms was filled out after obtaining their consent. The Lund-Mackay classification was used to assess the paranasal sinuses and OMC. The prevalence of abnormal findings and their associations with patients' age, sex, and subjective symptoms were analyzed by the chi-square test, independent-sample t-test, and analysis of variance. The level of significance was set at 0.05. Results: Abnormal findings in the paranasal sinuses were detected in 32.0% of patients, with a significantly higher prevalence in males (P<0.05), but no significant association with age (P>0.05). Epithelial thickening and retention cyst were the most common abnormal findings in the paranasal sinuses. According to the Lund-Mackay classification, 93% of the study population had normal sinuses (score<4). Concha bullosa and paradoxical concha were detected in 15.3% and 3.4%, respectively, with no significant association with the presence of septal deviation or Lund-Mackay classification (P>0.05). Conclusion: Considering the relatively high prevalence of abnormal findings in the paranasal sinuses, it appears that clinical symptoms alone are not sufficient to diagnose sinusitis. A more accurate strategy would be to assess radiographic images of the paranasal sinuses and use a classification system. Sinusitis should be suspected in patients receiving a high score in this classification.

  • We report 12 cases of paranasal sinusitis by the treatment of oriental medicines. Showing discharge from the nose. paranasal sinusitis is termed BIYEON(鼻淵) in the oriental medicine. Most of patient took GAMIBANGPUNGTONGSEONGSAN(加味防風通聖散). reported effect of antiphlogosis. antihistamine and antibiosis, for about five months. As a result the symptoms of paranasal sinusitis subsided. The radiographic diagnosis of sinusitis is generally based on opacification of the paranasal sinuses. Most of patients change the opacity of the maxillary sinuses on X-ray film in Water's view and Caldwell view by the treatment of Oriental medicine. We conclud that herbal medicines effect paranasal sinusitis.

  • Inverted papilloma arising from mucous membrane of the nasal cavity and paranasal sinuses is rare benign neoplasm, and usually unilateral arise from lateral wall of nasal cavity. This tumor is histologically benign neoplasm but clinically malignant, because of frequent recurrence and extensive bone destruction. And occasionally, this tumor can be transformed to squamous cell carcinoma or verrucous carcinoma. Recently, We have experienced a case of the inverted papilloma with verrucous carcinoma of the nose and paranasal sinuses and patient expired due to extension of intracranial cavity. We report our case with review of current literatures.

  • The Purpose of this study is to detect morphological changes of the maxilla following the operation of paranasal sinuses in the orthopantomogram. 1) The measurement of the angle set up by two reference lines which represent posterior aspect of the maxilla and skull base was made. 2) The mean angle in the post-operative patients showed significantly smaller than that in the normal subjects. 3) The forms of posterior aspect of maxilla were classified into 5 types. (flat, convex, concave, uneven and obliterated.) 4) In contrast with the convex type in the majority of normal subjects, approximately half of the post-operative patients showed the concave type. 5) These results may suggest that the superior part of the posterior aspect of the maxilla tend to depress following the operation of these paranasal sinuses.

  • 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.

  • Background Restoring orbital volume in large blowout fractures is still a technically challenge to the orbital surgeon. In this study, we restored the orbital wall using the combination of transorbital and transnasal approach with additional supports from the paranasal sinuses, and we compared the surgical outcome to that of a conventional transorbital method. Methods A retrospective review of all patients with pure unilateral blowout fractures between March 2007 and March 2013 was conducted. 150 patients were classified into two groups according to the surgical method: conventional transorbital method (group A, 75 patients, control group), and the combination of transorbital and transnasal approach with additional supports from the paranasal sinuses (group B, 75 patients, experimental group). Each group was subdivided depending on fracture location: group I (inferior wall), group IM (inferomedial wall), and group M (medial wall). The surgical results were assessed by the Hertel scale and a comparison of preoperative and postoperative orbital volume ratio (OVR) values. Results In the volumetric analysis, the OVR decreased more by the experimental groups than each corresponding control groups (P<0.05). Upon ophthalmic examination, neither the differences among the groups in the perioperative Hertel scale nor the preoperative and postoperative Hertel scales were statistically significant (P>0.05). Conclusions Our surgical results suggest that orbital volume was more effectively restored by the combination of transorbital and transnasal approach with additional supports from the paranasal sinuses than the conventional method, regardless of the type of fracture.

  • 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.

  • The maxillary sinus appeared first among the sinuses of the skull at 92 days of prenatal stage. The early formation of frontal sinus was observed at 157 days in the cranial most part of the frontal bone while the early formation of palatine sinus was observed at 170 days. A total of five fontanelles were observed in prenatal skulls of buffalo. The largest and unpaired fontanelle was anterior fontanelle. The mastoid and sphenoidal fontanelle were paired. The ossification of anterior fontanelle was first observed at 164 days. All the fontanelles were ossified completely prenatally.
