Introduction: Cone beam computed tomography (CBCT) is frequently used in surgery treatment planning in patients with cleft lip and palate (CLP). The aim of this study was to investigate the presence of different anatomical variations of patients with cleft lip and palate using CBCT images. Materials and method: CBCTs taken from consecutive patients (n =25; mean age 10.7±4 years, range 6.5–23 years) with a non-syndromic cleft lip and palate (CLP), between June 2014-2015, were systematically evaluated. Sinuses, nasopharynx, oropharynx, hypopharynx, temporo-mandibular joint (TMJ), maxilla and mandible were checked for incidental findings. Results: On 90.1 % of the CBCTs, incidental findings were found. The most prevalent ones were airway/sinus findings (78.1%), followed by dental problems, e.g. missing teeth (54%), nasal septum deviation (93%), middle ear and mastoid opacification, suggestive for otitis media (8%) and (chronic) mastoiditis (7%), abnormal TMJ anatomy (4.3%). Conclusions: Incidental findings are common on CBCTs in cleft lip and palate patients. Compared with the literature, CLP patients have more dental, nasal and ear problems. The CBCT scan should be reviewed by all specialists in the CLP team, stress being laid on their specific background knowledge concerning symptoms and treatment of these patients.
