The aim of this study was to determine the relative frequency of jaw lesions in Kuwait.
Biopsy records and microscopic sections of all jaw biopsies seen in the Department of Histopathology at Amiri Hospital, Kuwait, during the period January 2004 to December 2009 were reviewed. The biopsies were divided into three major groups: developmental/inflammatory/reactive lesions (group 1), cystic lesions (group 2), and tumors and tumor-like lesions (group 3). Groups 2 and 3 were subdivided into odontogenic and nonodontogenic.
Three hundred and eighty-five cases were reviewed. Of the 385 cases, 115 (29.9%) were in group 1, 178 (46.2%) in group 2, and 92 (23.9%) in group 3. Overall, radicular cysts (n = 95; 24.7%) were the most common biopsied jaw lesions, followed by chronic apical periodontitis (n = 59; 15.3%), dentigerous cysts (n = 51; 13.2%), and keratocystic odontogenic tumors (n = 30; 7.8%). In group 1, chronic apical periodontitis was the most frequent lesion (n = 59; 51.3%). In group 2, odontogenic cysts (n = 166; 93.3%) were more frequent than nonodontogenic cysts (n = 12; 6.7%), and radicular cysts (n = 95; 53.4%) were the most frequent lesions in this group. Odontogenic tumors (n = 61; 66.3%) were more frequent than nonodontogenic tumors (n = 31; 33.7%) in group 3. Keratocystic odontogenic tumors (n = 30; 32.6%) were the most frequent type of lesion in this group, followed by ameloblastoma (n = 17; 18.5%). Only 3 malignant lesions were found in this study.
Cystic and inflammatory lesions of the jaw are more common than tumors and tumor-like lesions of the jaw in Kuwait. The majority of inflammatory lesions that occurred in the jaw were related to periapical inflammation. Most cystic and tumorous jaw lesions were odontogenic in origin. Locally aggressive odontogenic tumors were relatively more common than nonaggressive ones. Malignant jaw tumors were relatively rare.
本研究旨在确定科威特颌骨病变的相对频率。
回顾了 2004 年 1 月至 2009 年 12 月期间科威特 Amiri 医院组织病理学系所见的所有颌骨活检的活检记录和显微镜切片。活检分为三组：发育性/炎症性/反应性病变（第 1 组）、囊性病变（第 2 组）和肿瘤和肿瘤样病变（第 3 组）。第 2 组和第 3 组进一步分为牙源性和非牙源性。
共 385 例患者接受了回顾性分析。在 385 例患者中，115 例（29.9%）为第 1 组，178 例（46.2%）为第 2 组，92 例（23.9%）为第 3 组。总体而言，根囊肿（n = 95；24.7%）是最常见的颌骨活检病变，其次是慢性根尖周炎（n = 59；15.3%）、含牙囊肿（n = 51；13.2%）和角化囊肿性牙源性肿瘤（n = 30；7.8%）。在第 1 组中，慢性根尖周炎是最常见的病变（n = 59；51.3%）。在第 2 组中，牙源性囊肿（n = 166；93.3%）比非牙源性囊肿（n = 12；6.7%）更常见，根囊肿（n = 95；53.4%）是该组中最常见的病变。在第 3 组中，牙源性肿瘤（n = 61；66.3%）比非牙源性肿瘤（n = 31；33.7%）更常见。角化囊肿性牙源性肿瘤（n = 30；32.6%）是该组中最常见的病变类型，其次是造釉细胞瘤（n = 17；18.5%）。本研究仅发现 3 例恶性病变。
在科威特，颌骨的囊性和炎症性病变比颌骨的肿瘤和肿瘤样病变更为常见。颌骨发生的大多数炎症性病变与根尖周炎症有关。大多数囊性和肿瘤性颌骨病变来源于牙源性。局部侵袭性牙源性肿瘤比非侵袭性肿瘤更为常见。恶性颌骨肿瘤相对少见。
