舌下腺囊肿口外型27例诊断与治疗

目的:探讨口外型舌下腺囊肿的临床特征、误诊原因及诊治要点。方法:对27例口外型舌下腺囊肿病例的临床资料进行回顾性分析。结果:27例口外型舌下腺囊肿有5例误诊。所有病例均行手术摘除舌下腺而治愈。结论:下颌舌骨肌发育缺陷,舌下腺穿过该肌裂孔或间隙突入颌下区是该病的发生机制。口内完整摘除舌下腺是根治口外型舌下腺囊肿的最佳方法。     

颌下口外型舌下腺囊肿的诊断及手术治疗

目的：探讨颌下区口外型舌下腺囊肿的诊断及治疗，避免临床上误诊误治。方法：对1998．3．-2008．11．经治的颌下区口外型舌下腺囊肿30例进行总结分析。结果：30例经局部检查，穿刺检查及淀粉酶检查，辅助B超检查作出颌下区口外型舌下腺囊肿诊断，经口内进路手术摘除舌下腺及与腺体粘连的囊壁，术后病理检查证实临床诊断，观察1-3年未见复发。结论：颌下区局部触及柔软囊性肿物、穿刺抽出蛋清样粘稠丝状液体及淀粉酶检查阴性，是颌下区舌下腺囊肿的诊断依据，手术彻底摘除舌下腺及切除与腺体粘连的囊壁是治疗成功的关键。

The treatment of sublingual gland tumours

This study assessed the clinical and histological features and therapeutic efficacy of 25 cases of sublingual gland tumours from 1998 to 2008. There were 17 female patients and 8 male, the ratio of females to males was 2.1:1. The mean age was 48.6 years. 4 cases were benign tumours (16%). 21 cases were malignant sublingual gland tumours (84%) and of these, 18 were adenoid cystic carcinoma (86%). Adenoid cystic carcinoma was mainly of the histological type, and the other histological classifications included mucoepidermoid carcinoma, pleomorphic adenoma, myoepithelioma, oncocytoma and polymorphous low-grade adenocarcinoma. Sublingual gland tumours are rare and most are malignant. For malignant sublingual gland tumours, early diagnosis and aggressive surgical treatment, especially for tumours with nerve involvement, is the key to improving prognosis. Free radial forearm flap or pectoralis major myocutaneous flap are appropriate methods for mouth floor reconstruction. For benign sublingual gland tumours, the resection of tumour and sublingual gland is the preferred treatment.     

舌下腺囊肿的诊断与鉴别诊断

舌下腺囊肿是一种常见的唾液腺黏液囊肿,临床上分为单纯型、口外型和哑铃型。舌下腺囊肿的临床诊断主要根据其临床特征、影像学检查、囊肿内容物检查和组织学检查等。口外型舌下腺囊肿因其异常的发生部位而易被误诊,需同多种颈部肿物相鉴别。文章就舌下腺囊肿的诊断与鉴别诊断做一概述。     

26例颌面部神经鞘瘤误诊原因分析

目的：分析颌面部神经鞘瘤误诊原因，进一步提高临床诊断治疗水平。方法：回顾26例颌面部神经鞘瘤误诊病例资料，总结分析误诊原因，以及治疗过程中存在和注意的问题。结果：26例误诊病例，术前诊断腮腺多形性腺瘤4例，腮腺恶性肿瘤3例，颧骨骨瘤1例，颈动脉体瘤4例，鳃裂囊肿1例，恶性肿瘤颈淋巴结转移3例．咽部恶性肿瘤2例，舌部纤维瘤4例，口底皮样囊肿2例，舌下腺恶性肿瘤2例。26例术后病理均证实为神经鞘瘤。结论：临床表现为局部肿块的颌面部神经鞘瘤，易与其他肿瘤混淆，应特别注意与类似病变鉴别诊断。     

Correct diagnosis for plunging ranula by magnetic resonance imaging

Plunging ranulas most commonly occupy the submandibular triangle and misdiagnosis inevitably leads to incorrect treatment. Three cases of plunging ranula are reported. The correct diagnosis resulted from the characteristic signs of magnetic resonance imaging (MRI). Treatment consisted of the total removal of the sublingual gland and evacuation of cystic contents by the intraoral approach. The cyst gradually regressed and disappeared within two months after surgery as confirmed by ultrasonography. All three cases have not experienced recurrence in the follow‐up period. MRI is a valuable method to correctly diagnosis plunging ranula. Total removal of the sublingual gland is the most reliable method to treat plunging ranula.     

A case of submandibular gland mucocele

Submandibular Gland Mucocele:The mucocele occuring in the submandibular region is rare, most cases originate in the sublingual gland. Here, we report a rare case of mucocele originating in the submandibular gland. In this report, we present such a case in a 7-year-old boy, who was treated by an extirpation of cyst with submandibular and sublingual gland     

The surgical anatomy of the sublingual gland

Because of its position, the sublingual gland is clinically important especially in the events of injuries and infections in the anterior part of the sublingual region. The morphology and relationships of this gland were studied by dissection methods applied on 80 fresh or formaldehyde fixed preparations of the mouth floor and of the tongue, which were partly (31 preparations) taken out together with the mandible. As for the shape of the gland, three main types were found: the cuneiform type which was the most frequent (71%), the pyramidal type which was less frequent (16%) and the fusiform type (13%) which comprised the case of a very elongated gland (up to 65 mm). The space in which the gland lied had four walls. Its internal wall consisted of the mylohyoid muscle and it comprised the hyoglossus muscle as well when the gland was very elongated. The inferior wall consisted of the mylohyoid muscle and sometimes it comprised also a narrow part of the superior surface of the geniohyoglossus muscle. An osseous depression on the internal side of the mandible represented the external wall of the sublingual gland space. The superior wall is clinically the most significant. It consists of the sublingual mucosa and a sublingual fold. This wall represents a main surgical access to the gland. In edentulous mandibles this mucous fold may be at the level of the upper mandibular border which may hinder the use of the lower dental prosthesis.     

先天性颌下腺导管扩张症的临床诊治

目的 探讨先天性颌下腺导管扩张症的临床特点及治疗方法。方法 2008年1月—2018年3月共收治7例先天性颌下腺导管扩张患儿,平均年龄5月22天;临床上表现为单侧的口底膨隆肿胀。7例患儿均在全麻下行患侧舌下腺腺体切除、颌下腺扩张部分导管切除及导管改道术,术中可见颌下腺导管口狭窄,部分导管呈扩张状态。结果 7例患者术后口底创口均愈合良好,无肿胀及囊肿发生。结论 先天性颌下腺导管扩张症患儿的发生年龄小,早期诊断与治疗有助于防止导管扩张加重,避免腺体萎缩、喂养困难以及阻塞呼吸;舌下腺腺体的同期切除可以避免术后舌下腺囊肿的发生。
