“…Previous studies using single morphology have suggested the following parameters as risk indicators of OSAHS: small jaw, 2,6,9 long pharynx, 14 retrognathia, 6,11 and decreased facial axis 25,26 in skeletal morphology; and increased soft palate and tongue area 10,11,27 in soft tissue morphology. Another study showed that tongue volume is correlated with BMI, 19 which can identify the risk factor of OSAHS with obesity.…”

Craniofacial morphological anomalies can be divided into two principal categories: skeletal anomalies and soft tissue anomalies. This study examined the hypothesis that the assessment of indices representing both skeletal and soft tissue can be used to appropriately identify the risk factor of obstructive sleep apnea–hypopnea syndrome (OSAHS). 232 suspected OSAHS male patients were examined with polysomnography and divided into two groups (202 males with OSAHS and 30 male controls without OSAHS). Cephalometric analysis was performed on all patients to evaluate craniofacial morphological anomalies. The measurement sites were as follows: skeletal morphology; soft tissue morphology; mixed morphology including mandibular plane to hyoid bone (MP-H); and jaw soft tissue (JS) ratio; a novel ratio we defined, between the area of jaw and area of tongue with soft palate. JS ratio increased with AHI as well as MP-H. MP-H and JS ratio showed significant but weak correlation with apnea–hypopnea index. JS ratio was significantly associated with an increased risk for severe OSAHS, even after adjusting age and BMI, its odds ratio was the greatest among these variables. These results showed that mixed craniofacial, skeletal and soft tissue morphology are correlated with AHI, and JS ratio may be a useful parameters to explain the characteristics of OSAHS in male patients.

In this communication, we report the current status of OSAS (Obstructive Sleep Apnea Syndrome) in the southern region of Higashikatsushika around Ichikawa City, our effort to improve patient QOL as well as to establish diagnostic and therapeutic methods, and the results of a comparison of therapeutic options with the focus on improvement of compliance by using nCPAP (nasal continuous positive airway pressure). We examined 112 patients who visited the Otolaryngology Department at Tokyo Dental College, Ichikawa General Hospital, with the chief complaint of nocturnal snoring or sleep apnea from January 2001 to April 2003 and underwent all-night PSG (polysomnography). Based upon the results of these all-night PSGs, 89 and 23 patients were diagnosed as having OSAS and simple snoring, respectively. Using the AHI classification of severity, 58 and 31 patients were assessed as having severe OSAS and mild OSAS, respectively. (1) nCPAP was tried in 61 patients, and 39 patients (63%) were able to continue it. After the introduction of nCPAP, surgery was performed in 18 patients (30%). As a result, weaning from nCPAP was successfully achieved in 10 cases, compliance with nCPAP was improved in six cases, alleviation of symptoms (decreased pressure) was seen in one case, and aggravation was noted in one case. In addition, four patients (7%) unilaterally discontinued nCPAP. (2) Surgery was performed in 34 patients, and 18 of them had surgery after nCPAP was tried. (3) We asked the dental department to make OAs (oral appliances) for 31 patients but seven of them did not attend the department, so a total of 24 patients used OAs. Fourteen patients (58%) were able to tolerate an OA for 3 months or more. Based on these results, we are hoping to achieve a better control of OSAS by combining nCPAP and other modalities.
