Abstract

Background

Pleomorphic adenoma (PA) is a common parotid tumor, yet due to the relative rarity of deep lobe PA (DLPA), there is a paucity of information about its clinical presentation and surgical outcomes.

Methods

We reviewed the charts of patients with previously untreated parotid PA between the years 1990 and 2015. Clinical parameters and surgical outcomes were compared between superficial lobe PA (SLPA) and DLPA.

Results

The cohort comprised 147 cases of DLPA and 222 cases of SLPA. DLPA were larger (median 2.6 cm vs. 2.0 cm, p < 0.001), more often discovered incidentally on imaging (33%, n = 48) and had unique presentations (pharyngeal mass, dysphagia, otalgia). Postsurgical complications were more frequently observed in DLPA (41% vs. 30% in SLPA, p = 0.025), mainly transient facial nerve weakness. DLPA also showed higher recurrence rates (n = 6, 4.1% vs. n = 1, 0.4%, p = 0.016).

Conclusions

Parotidectomy for DLPA carries a higher risk of complications and recurrence compared to SLPA.

腮腺切除术治疗深叶多形性腺瘤的并发症和复发率较高。

背景：多形性腺瘤（PA）是一种常见的腮腺肿瘤，但由于深叶PA（DLPA）相对罕见，有关其临床表现和手术效果的信息很少：我们回顾了1990年至2015年间既往未经治疗的腮腺PA患者的病历。方法：我们回顾了 1990 年至 2015 年间既往未经治疗的腮腺 PA 患者的病历，比较了浅叶 PA（SLPA）和 DLPA 的临床参数和手术效果：结果：研究组包括147例DLPA和222例SLPA。DLPA更大（中位数为2.6厘米，而SLPA为2.0厘米，P 结论：DLPA更大，而SLPA更小：腮腺切除术治疗 DLPA 的并发症和复发风险高于 SLPA。
