颌骨后腮腺肿瘤较少见。我院自1975年共收治4例,兹报告于下:见附表。讨论颌骨后腮腺肿瘤占腮腺肿瘤的4～12%,我院5年间共收治腮腺良恶性肿瘤35例,其中本病4例,占11%。本瘤多发生自腮腺的咽突部腺体,由于茎突下颌韧带的限制,肿瘤常生长成哑铃状。 Posterior parotid gland tumors are rare. Our hospital has treated 4 cases since 1975 and are hereby reported below: see attached table. Discussion The parotid tumor of the jaw accounts for 4-12% of the parotid gland tumors. 35 cases of benign and malignant parotid tumors were treated in our hospital for 5 years, including 4 cases of this disease, accounting for 11%. This tumor often occurs in the pharyngeal process glands of the parotid gland. Due to the limitation of the styloid and mandibular ligament, the tumor often grows into a dumbbell.
