Floating the uvula: an intraoperative method for detecting bifidity.

A bifid uvula, midline diastasis of the palatal muscles, and notching of the posterior hard palate have classically formed a triad diagnosing submucosal clefts. The uvula has thus served as a tool for clinicians to detect the earliest signs of clefting. In this case report, we discuss how mucosal lining may be held together by mucous viscosity, making it difficult to detect notching or a grossly bifid uvula. We demonstrate a simple intraoperative technique to easily overcome this force. This paper involves a case report of an 8-year-old female undergoing an adenotonsillectomy. A previously undetected bifid uvula was found only after floating the uvula in normal saline solution. This changed our surgical approach from a complete to a partial adenoidectomy. A bifid uvula may be considered the earliest form of a cleft palate, and more importantly, it has been shown in the literature to be associated with other anomalies as submucosal cleft, hyoplastic eustachian tube orifice, and absence of the salpingopharyngeal folds. The intraoperative technique of floating the uvula helps to overcome mucous viscosity and identify an otherwise missed bifid uvula.
