Cephalometric abnormalities in non-obese and obese patients with obstructive sleep apnoea

Abstract

The aim of this work was to comprehensively evaluate the cephalometric features in Japanese patients with obstructive sleep apnoea (OAS) and to elucidate the relationship between cephalometric variables and severity of apnoea.Forty-eight cephalometric variables were measured in 37 healthy males and 114 male OSA patients, who were classed into 54 non-obese (body mass index (BMI) <27 kg . m -2 , apnoea±hypopnoea index (AHI)=25.316.1 events . h -1) and 60 obese (BMI $27 kg . m -2 , AHI=45.628.0 events . h -1

Obstructive Sleep Apnoea Hypopnoea Syndrome and the Cranio Facio-hyoid Morphology in Adults: Linear and Angular Measurements

“…Similar study found the OPT/CVT to be lesser in the OSAHS group mean 4.5° and SD 2.91 [41]. Similar research found OPT/CVT to be also reduced in the obese OSAHS group (mean 1.1°, SD 2.6), than the control (mean 1.5°, SD 3.1) [42], A comprehensive cephalometric analysis of cranio-cervico-faciohyoid skeletal morphology in 100 male patients with obstructive sleep apnoea (OSA) and 36 male controls was performed, with aberrations in the OSA group features are; shorter dimension of cranial base with slight counter-clockwise rotation and depression of clivus; shorter maxillary length with normal height; maxillomandibular retrognathia related to nasion perpendicular plane (N⊥FH) despite normal angles of prognathism; 47% of the OSA group had mandibular retrognathia; increased anterior lower facial height and mandibular plane angle; reduced size of bony pharynx; inferiorly positioned hyoid bone at C4-C6 level; deviated head posture with larger cranio-cervical angle, and came with the conclusion that cephalometric analysis is highly recommended in OSA patients as one of the most important tools in diagnosis and treatment planning [43]. The linear measurements were higly correlated except that of the overbite and the overjet.…”

“…Also cephalometry is helpful in identification, forensics head and face reconstruction, plastic surgery, oral and maxillofacial surgery, orthodontics and clinical diagnosis and treatment planning (Williams et al, 1995;Sakakibara et al, 1999).…”

Cervical CT derived neck fat tissue distribution differences in Japanese males and females and its effect on retroglossal and retropalatal airway volume

“…Our results agree with the general idea that fat deposition and/or fatty infiltration in the surrounding areas of the pharynx would be related to the presence and severity of OSAS. 15,16,23,24 . However, it disagrees with Ciscar et al and Hora et al who found that the reduction on the transversal diameter of the airways was more associated with muscle hypertrophy than fat deposition.…”
