Materials and Methods: This descriptive study was conducted on 116 digital lateral cephalograms of 38 patients with skeletal Class I malocclusion (normal), 40 patients with skeletal Class II malocclusion with mandibular deficiency, and 38 patients with skeletal Class III malocclusion with mandibular excess. Both male and female patients were included. Using AutoCAD 2016 software, the anteroposterior dimension, height and surface area of the frontal and maxillary sinuses, mandibular body length and cephalometric indices including anterior and posterior cranial bases, and growth pattern indices were measured on lateral cephalograms. Results: Dimensions and surface area of the frontal and maxillary sinuses in skeletal Class III malocclusion were greater than those in other groups. These variables were significantly correlated with the mandibular body length. The coefficient for the correlation of height, width, and surface area of the frontal sinus with mandibular body length was 0.253, 0.284, and 0.490, respectively. The coefficient for the correlation of height, length, and surface area of the maxillary sinus with mandibular body length was 0.346, 0.657, and 0.661, respectively. These variables (except for the frontal sinus width) had a significant correlation with the anterior and posterior cranial bases. The frontal sinus width had a significant correlation with the anterior cranial base. These variables in males were greater than those in females. Conclusion: The dimensions and surface area of the frontal and maxillary sinuses in skeletal Class III malocclusion were greater than those in other groups. These variables (except for the frontal sinus width) had a significant correlation with the anterior and posterior cranial bases and mandibular body length.<\/jats:p>","DOI":"10.4103\/ejd.ejd_345_17","type":"journal-article","created":{"date-parts":[[2018,6,7]],"date-time":"2018-06-07T09:40:35Z","timestamp":1528364435000},"page":"253-261","source":"Crossref","is-referenced-by-count":24,"title":["Cephalometric association of mandibular size\/length to the surface area and dimensions of the frontal and maxillary sinuses"],"prefix":"10.1055","volume":"12","author":[{"given":"Soghra","family":"Yassaei","sequence":"additional","affiliation":[{"name":"Department of Orthodontics, Faculty of Dentistry, Shahid Sadoughi University of Medical Sciences, Yazd, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Akramsadat","family":"Emami","sequence":"additional","affiliation":[{"name":"Faculty of dentistry, Shahid Sadoughi University of Medical Sciences, Yazd, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sanam","family":"Mirbeigi","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Radiology, Faculty of Dentistry, Shahid Sadoughi University of Medical Sciences, Yazd, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"194","published-online":{"date-parts":[[2019,9,16]]},"reference":[{"key":"key-10.4103\/1305-7456.233867-1","first-page":"143","volume-title":"The study of the maxillary sinus areas in different orthodontic malocclusions","author":"Oktay","year":"1992","journal-title":"Am J Orthod Dentofacial Orthop"},{"key":"key-10.4103\/1305-7456.233867-2","first-page":"77","volume-title":"Frontal sinus index \u2013 A new tool for sex determination","author":"Kiran","year":"2014","journal-title":"J Forensic Radiol Imaging"},{"key":"key-10.4103\/1305-7456.233867-3","first-page":"22","volume-title":"Frontal sinus parameters in computed tomography and sex determination","author":"Akhlaghi","year":"2016","journal-title":"Leg Med (Tokyo)"},{"key":"key-10.4103\/1305-7456.233867-4","first-page":"91","volume-title":"Are frontal sinuses useful indicators of sex?","author":"Goyal","year":"2013","journal-title":"J Forensic Leg Med"},{"key":"key-10.4103\/1305-7456.233867-5","first-page":"451","volume-title":"The frontal sinus enlargement as an indicator of growth maturity in class III patients \u2013 A pilot study","author":"Guevara","year":"2013","journal-title":"Int J Med Sci Public Health"},{"key":"key-10.4103\/1305-7456.233867-6","first-page":"221","volume-title":"Enlargement of the frontal sinus","author":"Brown","year":"1984","journal-title":"Ann Hum Biol"},{"key":"key-10.4103\/1305-7456.233867-7","first-page":"191","volume-title":"Volumetric evaluation of the paranasal sinuses in normal subjects using computer tomography images: A stereological study","author":"Emirzeoglu","year":"2007","journal-title":"Auris Nasus Larynx"},{"key":"key-10.4103\/1305-7456.233867-8","first-page":"1101","volume-title":"Pneumatization of the paranasal sinuses: Normal features of importance to the accurate interpretation of CT scans and MR images","author":"Scuderi","year":"1993","journal-title":"AJR Am J Roentgenol"},{"key":"key-10.4103\/1305-7456.233867-9","first-page":"35","volume-title":"Digital lateral cephalometric assessment of maxillary sinus dimensions in different skeletal classes","author":"Urabi","year":"2012","journal-title":"J Univ Baghdad"},{"key":"key-10.4103\/1305-7456.233867-10","first-page":"244","volume-title":"Relationship between frontal sinus surface area and mandibular size on lateral cephalograms of adults","author":"Salehi","year":"2012","journal-title":"J Isfahan Dent Sch"},{"key":"key-10.4103\/1305-7456.233867-11","first-page":"542","volume-title":"The frontal sinus and mandibular growth prediction","author":"Rossouw","year":"1991","journal-title":"Am J Orthod Dentofac Orthop"},{"key":"key-10.4103\/1305-7456.233867-12","first-page":"265","volume-title":"Dimensional differences in the craniofacial morphologies of groups with deep and shallow mandibular antegonial notching","author":"Lambrechts","year":"1996","journal-title":"Angle Orthod"},{"key":"key-10.4103\/1305-7456.233867-13","unstructured":"Jacobson A.
