A patient developed isolated numbness, 1st confined to the lateral nose and upper lip, but later involving the cheek, lower lip, upper gingiva, and the palate. This numbness was later associated with paresis of the muscles of the upper lip and angle of the mouth and with ipsilateral lower lid droop (the "numb cheek-limp lower lid" syndrome). Squamous cell carcinoma was discovered infiltrating the infraorbital nerve and distal branches of the facial nerve. Cheek numbness associated with lower eyelid or upper lip weakness may herald a neoplasm affecting the infraorbital nerve and distal facial nerve branches.
一名患者出现孤立性麻木，起初局限于鼻外侧和上唇，但后来累及脸颊、下唇、上牙龈和腭部。这种麻木后来伴有上唇和口角肌肉麻痹以及同侧下睑下垂（“麻木脸颊-松弛下睑”综合征）。发现鳞状细胞癌浸润眶下神经和面神经远端分支。与下睑或上唇无力相关的脸颊麻木可能预示着影响眶下神经和面神经远端分支的肿瘤。
