Incidental findings on cone beam computed tomography scans in cleft lip and palate patients

Abstract

The high number of findings indicates that CBCT imaging is a helpful tool in the treatment of CLP patients not only related to alveolar bone grafting and orthognathic surgery but it also provides diagnostic information for almost all specialties involved in CLP treatment.

Evaluation of the anatomical variation in the nasal cavity and paranasal sinuses of patients with cleft lip and palate using cone beam computed tomography

“…In particular, when nasal septal deviation is located in the nasal valve area, a patient will be more predisposed to rhinosinusitis (25, 26). Kuijpers et al (17) reported that the frequency of nasal septal deviation in UCLP patients was 34 %, however, in our UCLP group, this frequency was found to be 91.7 % in both the anterior and posterior parts. The reason for this difference is likely due to the fact that both bilateral and unilateral CLP patients were evaluated in the study by Kuijpers et al (17) whereas in our study, only UCLP patients were examined.…”

“…In patients with UCLP, middle ear and mastoid problems, dental anomalies, and maxillary sinus volume shortage are observed frequently (17,18). Recently, investigations into nasal cavity and paranasal sinuses in CLP patients had increased, because rhinosinusitis was commonly observed in these patients (19).…”

Difference in maxillary sinus volumes of patients with cleft lip and palate

“…According to the guidelines of the European Commission in radiation protection of CBCT (SEDENTEXCT), these exams should not be requested for all patients, but for CLP treatment, its use is justified [11]. Moreover, CBCT is also replacing several MSCT studies due to its lower cost and lower radiation dose when compared [12].…”

Prevalence of fossa navicularis among cleft palate patients detected by cone beam computed tomography

“…These patients are known to have more ear, nose and throat problems and dental anomalies than noncleft patients, because of disturbed anatomy of this region. 1 CBCT imaging may be necessary for planning an alveolar bone graft procedure as well as for planning orthognathic surgery in cleft palate patients. Fossa navicularis is an anatomic variation, radiographically demonstrating as a notch-like dehiscence on the inferior aspect of the clivus.…”
