Pleomorphic adenoma represents a most common benign neoplasm of major salivary glands. Most occurrences of this benign tumor in the submandibular gland have been treated surgically without difficulty via transcervical approach. However, a few clinical problems in the transcervical approach have been mentioned, such as nerve injury or aesthetic scaring. In this study, we introduced the intraoral approach for the removal of the submandibular mixed tumor. In total, 12 cases of pleomorphic adenoma of the submandibular gland were treated via intraoral approach. The surgical technique and morbidity associated with this approach were reviewed. During surgery the tumor and submandibular gland are easily dissected from surrounding tissue and removed through intraoral incision. Early postoperative morbidity developed, such as a temporary paresis of lingual nerve and a temporary limitation of tongue movement, but recovered within a short-term period. No late complaints appeared, such as neurological discomforts. All patients were followed up for the recurrence of the tumor from 20 months to 10 years. One patient showed a tumor recurrence at the early stage of this approach. We propose that the benign mixed tumor of the submandibular gland could be removed easily via intraoral route without an external scar or nerve injury.
多形性腺瘤是大唾液腺最常见的良性肿瘤。下颌下腺中这种良性肿瘤的大多数病例通过经颈入路手术治疗并无困难。然而，经颈入路存在一些临床问题，如神经损伤或美观瘢痕。在本研究中，我们介绍了经口入路切除下颌下混合瘤。总共12例下颌下腺多形性腺瘤采用经口入路治疗。回顾了该入路的手术技术及相关并发症。手术过程中，肿瘤和下颌下腺很容易从周围组织中分离出来，并通过口腔内切口切除。术后早期出现了一些并发症，如舌神经暂时麻痹和舌运动暂时受限，但在短期内恢复。未出现晚期不适，如神经方面的不适。所有患者随访肿瘤复发情况，时间从20个月至10年。1例患者在该入路早期出现肿瘤复发。我们认为，下颌下腺良性混合瘤可通过经口途径轻松切除，不会留下外部瘢痕或造成神经损伤。
