To explore the correlation between the attachment type of lateral pterygoid muscle (LPM) and the position of temporomandibular joint (TMJ) disc in patients with temporomandibular disorders (TMD) by using wireless amplified magnetic resonance imaging detector (WAND) coupled with conventional head and neck joint coil for high resolution imaging of TMJ. Eighty-five patients with TMD diagnosed by oral and maxillofacial surgeons of Guizhou Provincial People's Hospital from October 2019 to January 2022 were collected. A total of 160 TMJ were included. There were 16 males and 69 females, aged (32.7±14.2) years. All patients were scanned with open, closed oblique sagittal and coronal WAND coupled head and neck coils with bilateral TMJ. Based on TMJ and LPM high resolution imaging, to explore the correlation between LPM attachment types and the position of TMJ disc in TMD patients, and to evaluate the potential clinical value of LPM attachment types in TMD patients. test and Pearson correlation analysis were used to evaluate the correlation between LPM attachment type and TMJ disc location. There were three types of LPM attachment: type Ⅰ in 51 cases [31.9% (51/160)], type Ⅱ in 77 cases [48.1% (77/160)] and type Ⅲ in 32 cases [20.0% (32/160)]. There was a significant correlation between the type of LPM attachment and the position of articular disc (=28.20, =0.002, =0.776). There was no statistical significance between the type of LPM attachment and the reversible displacement of articular disc (=0.24, =0.887, =0.825). There is a correlation between the attachment type of LPM and the position of the disc in TMD patients. WNAD coupled with conventional head and neck joint coil TMJ high resolution scan can provide reliable imaging evidence for TMD patients in evaluating the type of LPM attachment and the location of disc.
通过使用无线放大磁共振成像探测器(WAND)结合传统的头颈关节线圈对颞下颌关节(TMJ)进行高分辨率成像,探讨颞下颌关节紊乱病(TMD)患者翼外肌(LPM)附着类型与TMJ盘位置之间的相关性。收集了2019年10月至2022年1月期间贵州省人民医院口腔颌面外科诊断为TMD的85例患者。共纳入160个TMJ。其中男性16例,女性69例,年龄(32.7±14.2)岁。所有患者均使用开放式、闭口斜矢状位和冠状位WAND结合头颈线圈对双侧TMJ进行扫描。基于TMJ和LPM的高分辨率成像,探讨TMD患者LPM附着类型与TMJ盘位置之间的相关性,并评估LPM附着类型在TMD患者中的潜在临床价值。采用检验和Pearson相关分析评估LPM附着类型与TMJ盘位置之间的相关性。LPM附着有三种类型:Ⅰ型51例[31.9%(51/160)],Ⅱ型77例[48.1%(77/160)],Ⅲ型32例[20.0%(32/160)]。LPM附着类型与关节盘位置之间存在显著相关性(=28.20,=0.002,=0.776)。LPM附着类型与关节盘可复性移位之间无统计学意义(=0.24,=0.887,=0.825)。TMD患者LPM附着类型与盘位置之间存在相关性。WNAD结合传统头颈关节线圈TMJ高分辨率扫描可为TMD患者评估LPM附着类型和盘位置提供可靠的影像学证据。
