The primary method of diagnosis in craniofacial deformity patient is used by gross inspection. The study for objective analysis and evaluation in Korean maxillofacial soft tissue portions is rare and our normals have been based on Caucasian such as American. But it is difficult to apply it to ours so we studied the frontal photometric measurements for maxillofacial Korean normals. The photograph were taken with the subject sitting in head position parallel with interpupillary plane to the floor. During taking pictures, facial analyser by Obwegeser in Martin was used for correct measurements. 54 male and 57 female ages 14 to 15 years were selected from a group of 111 healthy middle school students in Inchon. 1. The vertical measurements in glabella-subnasale, subnasale-stomion and stomion-menton in the male were higher than in the female subjects in $14{\sim}15$ years old Korean, so middle and lower third face were higher than those of female(p<0.05). 2. The horizontal measurements of female was higher than those of male in the rt. and It. eye width but smaller in nose width and lip width(p<0.05). 3. There was no significant difference in gender compared with soft cheek and mention angle measurements When our reports were compared with american white population, the vertical proportions in Korean normals were similar to american and the line measurements in middle facial length, nose width and intercanthal distance were higher than those of american.

The purpose of this study was to investigate the radiographic images of the condylar head in clinically normal subjects and the TMJ patients using standardized projection technique. 45 subjects who have not clinical evidence of TMJ problems and 96 patients who have the clinical evidence of TMJ problems were evaluated, but the patients who had fracture, trauma and tumor on TMJ area were discluded in this study. For the evaluation of radiographic images, the author has observed the condylar head positions in closed mouth and 2.54㎝ open mouth position taken by the standardized transcranial oblique lateral projection technique. The results were as follows: 1. In closed mouth position, the crest of condylar head took relatively posterior position to the deepest point of the glenoid fossa in 8.9 % of the normals and in 26.6% of TMJ patients. 2. In 2.54㎝ open mouth position, condylar head took relatively posterior position to the articular eminence in 2.2% of TMJ patients and 39.6% of the normals. 3. In open mouth position, the horizontal distance from the deepest point of the glenoid fossa to the condyla head was 13.96㎜ in the normals and 10.68㎜ in TMJ patients. 4. The distance of true movement of condyalr head was 13.49㎜ in the normals and l0.27㎜ in TMJ patients. 5. The deviation of mandible in TMJ patients was slightly greater than that of the normals.

The primary method of diagnosis in craniofacial deformity patient is used by gross inspection. So we studied the frontal photometric measurements for maxillofacial Korean normals 44 male and 48 female ages 19 to 20 years were selected from a group of 92 healthy Kyung Hee university students in Seoul.. The photograph were taken with the subject sitting in head position parallel with interpapillary plane to the floor. During taking pictures, facial anallyser by Obwegeser(Martin Co., Germany) was used for correct measurements. The results of this study was followed. 1. In the linear measurements, all values of males were longer than those of females but middle third height and lower third height, facial width and nasal width of males were longer than those of females in p<0.05 2. The difference between right and left angular and linear measurement was insignificant. 3. In the horizontal facial ratios, interocular distance and nasal width were longer and mouth width were smaller in korean than in american(p<0.05). 4. In the vertical ratios, korean women have shorter facial height of lower third comparing with facial height of middle third than american(p<0.05). 5. In the vertical facial ratios, korean have smaller proportion below the stomion in the lower third department than american. (p<0.05).

This study was performed to aid for the case analysis and diagnosis of the maxillofacial deformities. A cephalometric analysis was made from 101 subjects over 18 years old, that consisted of 46 males and 55 females with normal occlusion, acceptable profile. The results o f this study were obtained as follows: 1. The tables of normals in adult male and female were made. 2. The angles of SNO were $65.5^{\circ}$ in male and $65.3^{\circ}$ in female and the horizontal linear measurements from 0 to NA(O-NA) were 9.0 mm in male and 8.9 mm in female. 3. The cranial base angles (SN-FH) were $8.2^{\circ}$in male and $10.3^{\circ}$ in female and the mandibular plane angles (OP-HP) were $28.1^{\circ}$ in male and $26.2^{\circ}$ in female. 4. The correlation of (O-NA) to S-O/S-A and S-O/S-N were higher than SNO, and the correlation of (N-A) to SNA and (N-B) were high.

The purpose of this study was to aid the case analysis and diagnosis of the maxillofacial deformities for orthognathic surgery. The applied method for analysis was a Cephalometries for Orthognathic Surgery(COGS) by Burstone. Lateral cephalograms were obtained from 59 subjects over 21 years old, that consisted of 30 males and 29 females with normal occlusion, acceptable profile. The results were as follows : 1. The author made the tables of means, standard deviations in each item, sex. 2. The author performed whether there was significance (P<0.05) between the registered male and female's measurement in each item.

Submucosal type cleft palate is subdivision of cleft palate. Because of late detection, the treatment - for example, the operation or the speech therapy - for the submucosal type cleft palate patient usually late. In this study, we want to find the objective characteristics of submucosal type cleft palate patient, comparing with the normal and the complete cleft palate patient. Experimental groups are 10 submucosal type cleft palate patients who got the operation in our hospital, 10 complete cleft palate patients. And, 10 normals as control group. The sentence patterns using in this study is simple 5 vowels. Using CSL program we evaluate the Formant, Bandwidth. We analized the spectral characteristics of speech signals of 3 groups, before and after the operation.
