An Incidental Palatine Finding: Benign or ‘Double Trouble’?

Alexander K. C. Leung, MD; Alex H. C. Wong, MD; and Benjamin Barankin, MD

A 12-year-old girl was seen because she had had a headache for 3 days straight. There was no history of fever, sore throat, earache, or visual aura. She did not have problems with phonation or swallowing. Her past health was unremarkable. In particular, there was no history of surgery in the oral cavity. She had had 2 episodes of otitis media in the past.

During the physical examination, bifurcation of the uvula was noted. The rest of the examination results were normal.

Answer: Bifid uvula

This patient has a bifid uvula, which refers to a partial or total bifurcation of the uvula.


Bifid uvula occurs in approximately 10% to 18% of American Indians,1-3 10% of Japanese,2 6.8% of Chinese,2 0.4% of Israelis,4 0.2% to 7.5% of white Americans,2,5,6 and 0.2% of African Americans.2

The wide variation in reported prevalence in part might be due to the different diagnostic criteria used, such as some form of uvula cleft versus full-length uvula cleft, as well as accuracy in the detection of small degrees of bifidity. 


This benign condition has an autosomal dominant mode of inheritance with incomplete penetration.7 Bifid uvula is more common in males than in females.5,7

The condition results from an incomplete fusion of the uvula during embryonic development.


Physical examination usually reveals a bifurcated uvula or occasionally a stunted uvula. A bifid uvula may not always be apparent on physical examination, because mucous viscosity can hold a bifid uvula together.8 Floating the uvula in normal saline solution may assist in the identification of this anomaly.8 Bifid uvula is a marker for a submucous cleft palate.9 In one study, bifid uvula was present in 60% of patients with submucous cleft palate.10 Bifid uvula may be associated with an absent salpingopharyngeal fold, hypoplastic eustachian tube orifices, and hypoplastic/aplastic musculus uvulae.8

The condition usually is asymptomatic. Some affected patients may have a hypernasal resonant speech.8

Bifid uvula often is an isolated malformation but can be a component manifestation in various genetic syndromes such as Loeys-Dietz syndrome,11 Stickler syndrome,12 Apert syndrome,13 van der Woude syndrome,14 and 22q11.2 deletion syndrome.15


Affected individuals, especially those with associated submucous cleft palate, are at risk for velopharyngeal insufficiency and hypernasal speech.9,16

Children with bifid uvula may be at slightly increased risk of otitis media. A retrospective study17 based on chart review of 44 white children with bifid uvula found that children with bifid uvula, when compared with age-matched controls (n = 86), were more likely to experience one episode of acute otitis media (64% versus 49%) and more than 3 episodes of acute otitis media (16% versus 8%) during the first year of life, but the difference did not reach statistical significance. By 3 years of age, the incidence of acute otitis media in the 2 groups was nearly equal. 

In another study9 involving 80 children with bifid uvula, 25 children were studied in detail, of whom 12 (48%) had a history of recurrent acute otitis or persistent otitis media with effusion. Other authors5 did not find an increased incidence of otitis media with effusion in children with bifid uvula.


A bifid uvula is a benign condition. No treatment is necessary. For patients with velopharyngeal insufficiency and hypernasal speech who require adenoidectomy, hypernasality may worsen postoperatively.9 

In addition, asymptomatic patients with associated submucous cleft palate can develop hypernasal speech after adenoidectomy.10 As such, adenoidectomy should be avoided in patients with bifid uvula. If adenoidectomy has to be contemplated, nasopharyngoscopic investigation prior to adenoidectomy is indicated so that patients can be counseled appropriately prior to surgery.9
