Parapharyngeal tumors are relatively rare tumors of head and neck. In general, pleomorphic adenoma is one of the most common benign tumor of the parapharyngeal region. Various approaches have been described in the literature for removal of parapharyngeal tumor with mandibulotomy generally carried out for large tumors. Here, we describe removal of a large parapharyngeal pleomorphic adenoma transcervically without mandibulotomy which subsequently turned out to be one of the largest ever reported in the literature and describe how large tumors of parapharyngeal can be removed with minimal invasive approach with mandibulotomy kept as a backup thereby avoiding complications associated with mandibulotomy.
咽旁肿瘤是头颈部相对少见的肿瘤。一般来说,多形性腺瘤是咽旁区域最常见的良性肿瘤之一。文献中描述了多种切除咽旁肿瘤的方法,对于大型肿瘤通常采用下颌骨切开术。在此,我们描述了经颈部入路切除一例大型咽旁多形性腺瘤,且未行下颌骨切开术,该肿瘤后来被证明是文献中报道过的最大的此类肿瘤之一,并阐述了如何通过微创入路切除大型咽旁肿瘤,同时将下颌骨切开术作为备用方案,从而避免与下颌骨切开术相关的并发症。
