Congenital facial cleft is a rare entity and appears along by the line of different processes of the facial development. An isolated cleft of the nose has been reported not often in the literature. We treated a patient with an isolated nasal cleft associated with undefined cranial anomaly. On 3D CT scan was seen a bony cleft traversing the pyriform aperture lateral to the anterior nasal spine. The nasal septum and frontal process of the maxilla were intact. There also was found bilateral bony defects in the frontal bone and bilateral frontal boss. The nasal cleft and frontal defect and boss were corrected by two stages: anterior two-third of the cranial vault with bilateral frontal boss was remodeled at the age of two years and the nasal cleft was repaired with a local rotation flap at age 3.

The aim of this study was to investigate the variation in shape, size and area of the pharynx and adenoids, and to analyze the relationship between pharyngeal cavity and upper facial cranium which effected on morphology of those parts in Korean. Age changes and sex differences in those areas were comprised in this study. Materials included 272 lateral cephalograms, which were divided into 4 groups by age; (1) 7-year-old group consisted of 29 males and 30 females, (2) 12-year-old group consisted of 30 males and 30 females, (3) 17-year-old group consisted of 30 males and 40 females, (4) 20-year-old group consisted of 37 males and 46 females. In subjects each variable was measured and evaluated statistically introducing 17 reference points and 17 reference lines respectively. Conclusions from this study were as follows. 1. Linear measurements of the bony nasopharynx revealed that the depth and height were larger in male than those in female in 17 and 20-year-old groups. 2. Linear measurements of the upper facial cranium were larger in male than those in female in all age groups. 3. Angular measurements of the bony nasopharynx and upper facial cranium did not show, on an average, sex differences in each age group. 4. As regards area of the bony nasopharynx, it increased gradually with age in both sexes. And the area was greater in male than that in female in 17 and 20-year old groups. 5. There were sex differences in area of the adenoids of which the area was larger in male than that in female in 17 and 20-year-old groups. And the area reached a peak at 17-year-old group in male and at 12 year-old group in female. 6. Area of the pharyngeal cavity increased gradually with age in both sexes, but no sex differences were noted in each age group. 7. Rate of area of the adenoids to that of the pharyngeal cavity decreased continually with age, and no sex differences were noted in all age groups. 8. In amounts and its differences of the growth, there were sex differences in the posterior upper facial height, and were not in area of the bony nasopharynx, pharyngeal cavity and adenoids in each age group.

Purpose: In this study, we retrospectively investigated the medical records of patients with facial fractures and suspected cranial injuries in order to determine if there was any relationship between various facial fracture patterns and cranial injuries. Methods: Medical records were reviewed to identify patients diagnosed with facial fractures who underwent cranial computed tomography (CT) scans. Records were reviewed for gender, age, injury mechanism, facial fracture pattern, and presence or absence of cranial injuries. Facial fracture patterns were classified as isolated fractures (tripod, zygomatic arch, maxilla, orbit, and mandible), combined fractures, or total fractures. Cranial injuries included skull fractures, traumatic subarachnoid hemorrhages, subdural hemorrhages, epidural hemorrhages, and contusional hemorrhages. All cranial injuries were established by using cranial CT scans, and these kinds of cranial injuries were defined radiologically-proven cranial injuries (RPCIs). We evaluated the relationship between each pattern of facial fractures and the incidence of RPCIs. Results: Of 132 eligible patients with facial fractures who underwent cranial CT scans, a total of 27 (20.5%) patients had RPCIs associated with facial fractures. Falls and slips were the most common causes of the fractures (31.8%), followed by assaults and motor vehicle accidents (MVAs). One hundred one (76.5%) patients had isolated facial fractures, and 31 (23.5%) patients had combined facial fractures. Fractures were found most commonly in the orbital and maxillary bones. Patients with isolated maxillary fractures had a lower incidence of RPCIs than those with total mandibular fractures. RPCIs frequently accompanied combined facial fractures. Conclusion: Combined facial fractures had a significant positive correlation with RPCIs. This means that facial fractures caused by stronger or multidirectional external force are likely to be accompanied by cranial injuries.

Purpose: Authors tried to analyze the influence of individual facial aesthetic subunits on the cognition of facial attractiveness in public and suggest a mathematical model which explain the facial attractiveness. Methods: Independent facial aesthetic subunits are extracted from facial photographs from three women (11 frontal and 7 lateral aesthetic subunits). Each facial subunits of three women are rated in terms of relative rank by 164 peoples (68 man and 96 woman, average age was 32.4, and ranged ${\pm}$ 9.8 years). $x^2$-test and categorical regression analysis were performed. Results: There was no difference in the aesthetic preference in terms of ages or sexes in large. Beautification of individual aesthetic subunits can predict the overall facial attractiveness up to 42.1% in frontal face (Adjusted $R^2$=0.421, F=6.39, p=0.000 < 0.05) and 22.7% in lateral face (Adjusted $R^2$=0.227, F=4.42, p=0.000 < 0.05). Aesthetic appearance of eyes (p=0.001), upper face (p=0.034) in frontal face and midface (p=0.000) in lateral face are statistically important factors in the cognition of facial attractiveness. Conclusion: Authors experimently proved that harmony and balance among facial aesthetic subunits are the most important factors, in embarking on facial aesthetic plastic surgery, for better enhancement of facial attractiveness.

Purpose: The nasal bone fracture is the most common type of facial bone fracture. In making a diagnosis, physical findings are much more important than the simple radiologic findings. Facial bone CAT scan can provide the accurate diagnosis and the correct location of nasal bone fractures, so it can be lessoned with proper intervention. The aim of this study was to evaluate the usefulness of facial bone CAT scan in the diagnosis of nasal bone fractures. Methods: The medical records and facial bone CAT scan of 45 patients clinically suspected nasal bone fracture but was not diagnosed on simple radiologic findings were analyzed. Results: All of the 45 patients were confirmed as nasal bone fractures in the facial bone CAT scan. The most common cause of fracture was assault. The mean age was 23.2 years. Physical findings were tenderness (100%), swelling(93.3%), epistaxis(66.6%), deviation (42.2 %), external wound(17.7%) and crepitus(4.4%) in order. Conclusions: It was concluded that the simple radiologic findings can not be conclusive, where the physical findings indicate a suspected nasal bone fracture. The facial bone CAT scan was more reliable for the correct diagnosis and follow-on treatment.

Purpose: This study aimed to measure the bilateral differences of facial lines in spherical coordinates from faces within a normal range of asymmetry utilizing cone-beam computed tomography (CBCT). Materials and Methods: CBCT scans from 22 females with normal symmetric-looking faces (mean age 24 years and 8 months) were selected for the study. The average menton deviation was $1.01{\pm}0.66$ mm. The spherical coordinates, length, and midsagittal and coronal inclination angles of the ramal and mandibular lines were calculated from CBCT. The bilateral differences in the facial lines were determined. Results: All of the study subjects had minimal bilateral differences of facial lines. The normal range of facial asymmetry of the ramal and mandibular lines was obtained in spherical coordinates. Conclusion: The normal range of facial asymmetry in the spherical coordinate system in this study should be useful as a reference for diagnosing facial asymmetry.

For a minimally invasive approach to access the facial nerve, we designed an extended epitympanotomy via a transmastoid approach that has proven useful in cases of traumatic facial nerve palsy and pre-cholesteatoma. To evaluate the surgical exposure through an extended epitympanotomy, six patients with traumatic facial nerve palsy were enrolled in this study. The same surgical technique was used in all patients. Patients were assessed and the degree of facial nerve paralysis was determined prior to surgery, 1-week post-operatively, and 6-months post-operatively using the House-Brackmann grading system. In all cases, surgical exposure was adequate. All patients with traumatic facial nerve palsy were male and the age range was 13 to 83 years. In all cases, the location of the facial nerve damage was limited to the area between the first and second genu. Symptoms of all the patients improved by 6 months post-operation (p=0.024). There were no complications in any of the patients. Extended epitympanotomy is useful for safe, rapid surgical exposure of the attic area, sparing the patient post-operative dimpling, skin incision complications, and lengthy exposure to anesthesia. We suggest that surgery for patients with facial nerve palsy secondary to trauma be performed using this described technique.

The purpose of this study is to classify and recreate the grooming styles of facial hair sported by noblemen during the Joseon Dynasty. Using existent portraits painted during this period as corroborative materials, this study has identified the traditional grooming styles of facial hair sought by noblemen in this age. This study has utilized 30 facial hair styles found in the portraits of noblemen inherited from the Joseon Dynasty, which take up the majority of the portraits currently remaining in Korea. To recreate grooming styles of facial hair, this study has divided facial hair into three types according to its location: beards, moustaches and whiskers. Based on the analysis of these divided grooming styles, this study has recreated grooming styles of facial hair by using artificial modelling heads, artificial hair, artificial glue, scissors, and a comb. The grooming styles of facial hair recreated by this study are closest to those that noblemen sought and did wear during the Joseon Dynasty. The results of this study are as follows. First, they groomed their moustaches in the 八 shape. Next, they wore their beards in the shape of an inverted triangle. Finally, they also grew and groomed whiskers. Though there are individual differences in the location, length, and volume of facial hair, noblemen in the Joseon Dynasty generally sought to wear their facial hair neat and long. Little research has been done to recreate and present noblemen's grooming styles of facial hair focusing on portraits. Thus, the findings of this study are expected to be utilized as basic materials for the education and research of grooming styles of facial hair according to ages. They can also be used as basic materials for recreating facial hair in historical dramas.
