Abstract
Goal: The purpose of this systematic review was to examine the trends of clinical intervention research for individuals with lifelong cases of bilateral cleft lip and palate. The examined literature covered surgical corrections, orthodontic and prosthetic treatments, speech-language development, and the psychosocial aspects of the condition.

Method: Eight databases were searched to identify articles related to bilateral cleft lip and palate published between 2000 and September 2020. All documents containing the words ¡°bilateral cleft lip and palate¡± in the title were searched, and documents were excluded according to the exclusion criteria. Studies that reported results without classifying cleft palate types were also excluded.

Results: A total of 212 articles were analyzed. All subjects were classified and analyzed based on 10 periods of lifecycles. Studies on bilateral cleft lip and palate were found to be steadily increasing; research was also being actively conducted in various countries. Bilateral cleft lip and palate were most actively studied in childhood, followed by adolescence, late childhood, and then early adulthood. The most frequent research topics were oral and maxillofacial surgery (simple structure/treatment result) and dentistry (simple structure/treatment result). The number of speech-language ability studies related to the recovery of velopharyngeal function and psychosocial studies associated with quality of life was low in comparison.

Conclusion: This review found that studies on oral and maxillofacial surgery (simple structure/treatment result) and dentistry (simple structure/treatment result) were the most abundant. This result suggests that more studies on speech-language outcomes and psychosocial aspects are needed.
