In Victor Hugo's The Man Who Laughs, the protagonist has a facial cleft. The authors aimed to comprehend the psychological experience of a patient with a facial cleft by analyzing this novel. The novel concerns the life of a young nobleman, Gwynplaine, disfigured as a child, who travels with his protector and companion, the vagabond philosopher Ursus, and Dea, a baby girl he rescued. During the oppressive rule of the king, one of his adversaries was Lord Linnaeus Clancharlie, who had taken refuge in Switzerland. The tyrannical monarch ordered the execution of Gwynplaine's father and commissioned a surgeon, Dr Hardquannone, to carve the boy's face into a perpetual grin. The king declared that he should "laugh forever at his fool of a father." Subsequently, the king sold the boy to a group who specialized in the mutilation and disfigurement of children. On the psychology of a boy with an appearance giving the impression of laughing, Hugo wrote: "By laughing Gwynplaine made people laugh. However, he wasn't laughing. His face laughed, his thoughts did not." When Ursus met Gwynplaine, Ursus asked the boy: "What are you laughing at?" The boy replied: I'm not laughing. Ursus: Then you are terrible. Gwynplaine's unnatural laughter, which stems from an artificial deformation of the muscles, is a silent form of laughter. It represents the eternal laughter of those who do not truly laugh, signifying emotional emptiness and an accompanying sense of indifference. Plastic surgeons can restore an "unnatural laughing face" to a "natural smiling face."
