中文摘要 | 背景:人工植牙在上下顎缺牙處已經是扮演不可或缺的角色。長期缺牙的齒槽骨也面臨齒槽骨吸收的情況,上顎後牙區更因爲較軟的骨質、齒槽骨吸收以及上顎竇氣息作用(Pneumatization)使得在上顎後牙區進行人工植牙贗複,往往需要同時或術前接受鼻竇增高手術。爲了降低上顎鼻竇增高手術的併發症,上顎竇的解剖構造的限制以及病理學的病灶是可以在術前就檢查出來的。因此本研究的目的是利用電腦斷層影像來分析上顎竇的解剖構造及病理學的病灶。 材料與方法:113位電腦斷層影像,男性53位、女性60位:平均年齡爲48.64±15.81歲。電腦斷層影像資料經Implant Max®軟體重組,定位上顎竇的中隔及病理學的病灶在全口無牙及局部無牙區出現的機率並加以記錄。 結果:一、電腦斷層影像有上顎竇中隔影像存在的比例佔47.8%(108/226),全口無牙病患出現中隔的比例佔47.5%(29/61):局部無牙病患出現中隔的比例佔47.9%(79/165),上顎竇前半段出現中隔的機率佔20.8%(47/226):中半段出現中隔的機率佔14.6%(33/226):後半段出現中隔的機率佔27%(611226)。斗、上顎竇病理學的病灶存在的比例佔15%(341226),全口無牙病患出現上顎竇病灶的比例佔6.6%(4/61):局部無牙病患出現上顎竇病灶的比例佔18.2%(30/165)。結論:上顎竇的中隔及病理學的病灶出現的機率是否因人而異,並沒有統計上的差別。希望藉由此研究可以提供人工植牙術前評估及診斷的參考。 |
英文摘要 | Background: Dental implant plays an important role in both maxillary and mandibular posterior edentulous ridges. Rehabilitation of the edentulous maxilla presents with significant difficulties such as poor bone quality, severe resorption. and pneumatization of the maxillary sinus. To minimize the complication of the sinus augmentation, presurgical examination of anatomy limitation and pathology of maxillary sinus is necessary. The aim of this study was to analyse the anatomic structure and pathology of the maxillary sinus in computerized tomographic images. Material and Method: The sample population consists of 113 patients (53 males and 60 females, with a mean age of 48.64+15.81 years). Data from 226 sinuses were analyzed from reformatted CT images utilizing implantMax® software. The location of the sinus septum and pathology were located on the cross section view. Statistical analysis was performed using Student t-tests to determine the prevalence and the location of the sinus septum and pathology in the edentulous and partial edentulous segments. Results: I. The prevalence of maxillary septa in CT images were found 47.8% (108/226): completely edentulous patients presented with 47.5% (29/61) of the total septa, while 47.9% (79/165) of the septa were identified in partially edentulous patients. Analysis of the anatomic location of the septa within the sinus revealed that 20.8% (47/226) septa were located in the anterior region, 14.6% (33/226) were in the middle, and 27% (61/226) were in the posterior region. II. The prevalence of sinus pathology in CT images was 15% (34/226) completely edentulous patients presented with 6.6% (4/61) of the total pathology, while 18.2% (30/165) of the pathology were identified in partially edentulous patients. Conclusion: The prevalence of sinus septa and pathology not significant in both male and female. To avoid unnecessary complications during sinus augmentation procedures, presurgical identification of the anatomic structures inherent to the maxillary sinus are required. |
