“…The method described in our study can be correlated to the "puffed cheek" technique used in computed tomography (CT) as first described by Weissman and Carrau (2001) [16] and reviewed in Henrot et al [17] and Çelebi et al [18]. Here, in order to improve visualization of oral cavity tumors, conventional contrast-enhanced axial CT scans are performed in patients who are asked to purse their lips and blow air into their cheeks (alternatively, water can be used, as described by Fatterpekar [19]).…”

Purpose To describe a new B-mode ultrasound examination technique to assess cheek tumors. Materials and Methods 30 cheek oral cavity lesions of different histological types (11 benign and 19 malignant) from 23 patients (11 women and 12 men, 7–82 years old, mean age of 49.5 years) were analyzed. Transcutaneous oral B-mode ultrasound (5–12 MHz transducer) was carried out in two stages. Initially it was performed conventionally with an empty mouth. Next, the patient was asked to keep their oral cavity filled with water (like when using a mouthwash) during imaging for the new test examination technique. The anatomical layers of this region and the characteristics of the tumors were evaluated. Lesions were classified as ill defined, partially defined, or defined. Conventional findings were compared to those of the new technique using the Wilcoxon signed-rank test. Ultrasound results were compared to histological findings analyzed by an independent team. Results The conventional empty mouth technique was able to confidently define lesion extension in only 6 of the 30 lesions, while the water-filled mouth technique was able to confidently define lesion extension in 29 of the 30 lesions (p<0.00001). Conclusion We present a novel technique that dramatically improves ultrasound staging of cheek oral cavity tumors. In addition to the increase in ultrasound accuracy, this technique does not require any special equipment or extra cost, is very well tolerated by patients, and thus should be considered in the evaluation of every patient undergoing transcutaneous cheek ultrasound for oral cavity lesion characterization.

“…Cone beam computed tomography (CBCT) is a basic examination used in dentistry in situations where conventional X-rays do not allow one to obtain sufficient accuracy for diagnostic purposes [17][18][19][20][21][22][23][24][25][26][27][28][29]. CBCT is primarily used to assess pathology in hard tissues.…”

“…The 'puffed cheek' maneuver is described as a method supporting CT diagnostics of lesions in the oral cavity, oropharynx, hypopharynx, and nasopharynx. By inflating the oral cavity and mouth vestibules with air while the patient's lips remain sealed during the scan, this technique improves soft tissue lesion detectability and delineation [24][25][26][27][28][29]. Other techniques include the modified Valsalva and phonation maneuvers.…”

Background: An accurate determination of the biological width and the relationship of the cemento-enamel junction with the border of the alveolar bone is crucial during a clinical crown-lengthening (CCL) procedure. The aim of this study was to present a technical note about the retraction techniques in cone beam computed tomography (CBCT) prior to CCL, highlighting the significant enhancement in procedural accuracy and predictability that these techniques offer. Methods: Clinical and radiological examinations should be performed before a CCL procedure. It is necessary to determine the length of the tooth crowns, the periodontal pockets’ depth, and the phenotype of the gingiva. The ideal CBCT examination should be performed with soft tissue retraction. This can be achieved using retractors or cotton rolls. Results: Retraction of the lips, cheeks, and tongue allows one to assess the marginal gingiva, the cemento-enamel junction, and the alveolar bone. A detailed plan of the CCL procedure, which involves retraction, ensures both the aesthetic appeal and the achievement of a newly defined gingival zenith, enhancing the overall visual harmony. Conclusions: Compared with conventional radiographic imaging, the soft tissue retraction maneuver in CBCT prior to CCL surgery offers an effective approach to the evaluation and diagnosis of soft and hard tissue. This is because of the detailed planning of the aesthetic CCL procedure. Such an approach leads to superior aesthetic outcomes in dentistry, contributing to the advancement of aesthetic dentistry through a harmonious blend of art and science.

“…Although dynamic maneuvers in the course of CT assessments have been described in the late 1980's [7], the corresponding clinical benefits have been very scarcely reported. Several maneuvers have been described so far including the "eee" phonation for glottis carcinomas [8], the modified Valsalva for hypopharyngeal carcinomas [9,10], the puffed cheeks for the lips and internal cheek surfaces [9,[11][12][13][14] and the open mouth for the oral cavity and the oropharynx [9,13]. The corresponding rationale was to stretch both the mucosa and the deep spaces at the vicinity in order to improve tumor delineation and in some cases, avoid metallic dental artifacts.…”
