OBJECTIVE: This work describes a new method for recording nasal fracture in skeletonized individuals, suitable for use in biocultural studies of violence and fracture in past societies. METHODS: The method consists in recording the 'side of fracture', 'side of deviation', 'type of fracture', 'other facial fractures', and stage of 'bone remodeling'. RESULTS: A lateral impact force to the facial area is typical of interpersonal violence. This may result in a unilateral nasal fracture and/or a laterally deviated nose. Given the predominance of right-handedness in human populations, side of fracture and, especially, side of deviation, may be useful indices of interpersonal violence. As regards fracture type, although a distal fracture of the nasal bones is the most common type, their comminution may be associated with higher impact forces. The presence of other facial fractures may also be an indicator of high-energy impacts. CONCLUSIONS: Different patterns of nasal trauma may be consistent with different etiologies. SIGNIFICANCE: The method is focused at improving our ability to distinguish the direction and type of impact that caused the injury and, in particular, whether, at a population or sub-group level, such injuries are likely to be predominantly due to violence or to other causes. LIMITATIONS: Well healed fractures of the nasal bones or injury to the septum may be difficult to identify. Also, it is not possible to confirm if nasal and other facial fractures are temporally concurrent. SUGGESTIONS FOR FURTHER RESEARCH: To test this method using skeletal collections with known trauma history or 3D prints of modern nasal injuries of known etiologies.

Multilobular tumor of bone (MLTB) is an infrequent, slow-growing, bone neoplasm formed predominantly on the head. These tumors can behave as malignant neoplasms clinically and pathologically and can metastasize occasionally. No cases of MLTB in rodents have been reported, to our knowledge. We describe a novel case of an MLTB in a guinea pig. An adult guinea pig had an exophytic mass fixed on the frontal bone, maxilla, and nasal bone. On radiography, the mass had a spherical contour and variable density and was formed on the surface of the cranial bones. The mass was excised surgically. The cut surface was light-yellow to milky-white and had a granular texture with fine fibrous septa. Histologically, the neoplasm had a multilobular pattern, which consisted of many islands of bone and/or cartilage matrix surrounded by small cells and separated by fibrous septa, which closely resembles the equivalent neoplasm in dogs.

Tumour-to-tumour metastasis is a rare phenomenon. It occurs when a primary tumour is a recipient of a separate tumour within the same individual. We present a case of a 66-year-old woman with known breast cancer who presented with one-sided nasal symptoms. Examination and imaging revealed a unilateral polyp arising from the skull base. She underwent endoscopic polypectomy with the histology demonstrating tumour-to-tumour metastasis from a breast carcinoma to an olfactory neuroblastoma, a rare sinonasal tumour. Clinicians should be cautious of distant metastases in any patient presenting with head and neck symptoms and a known primary tumour. This is the first documented case of this type.

Nasal fracture accounts for over 50% of facial fractures and is a frequent presentation to ear, nose and throat emergency clinics. Optimal management of nasal injuries with deformity is by manipulation under anaesthetic and should be offered when appropriate. A healthy 27-year-old woman presented with a lateral nasal wall mass with purulent discharge 1 month following manipulation. CT imaging revealed a mass arising from fragments of the nasal bone, consistent with an abscess. Bone fragments and purulent material were initially debrided, with a subsequent formal excision of a persistent granuloma performed with an excellent cosmetic outcome. This appears to be the first description of a granuloma resulting from a closed reduction-manipulation of a nasal fracture.

INTRODUCTION: Peripheral osteoma, which arises from the periosteum, commonly develops in the head and neck region and is found frequently in the mandible, maxilla, and paranasal sinuses. However, osteoma of the face, especially from the nasal bone, is quite rare. PATIENT CONCERNS: A 34-year-old female visited our outpatient department with a small mass on the nose. She had n laser treatment of nevus at the same spot 14 years before, and it had enlarged slowly since 10 years before. DIAGOSIS: Computed tomography scan revealed a 0.7â×â0.5âcm sized radio-opaque tumor of the nasal bone. INTERVENTIONS: Under general anesthesia, surgical excision was performed through a transcolumellar and infracartilaginous incision. The excised tumor was a 0.7â×â0.5âcm sized hard mass. OUTCOMES: Biopsy confirmed it as a peripheral osteoma. After tumor removal, structural stability of nasal framework including bone and cartilage was maintained, and symmetry of the nasal dorsum was acquired. CONCLUSION: Chronic osteoma can compress the abutting structures. In the case of the nose, either structural instability or asymmetry can occur. By applying open rhinoplasty techniques, postoperative scars could be hidden and additional correction of the affected structure could be carried out if necessary. As a result, the surgeon can achieve the functional and esthetic outcomes simultaneously.

OBJECTIVE: Our aim was to describe hard- and soft-tissue asymmetry in people who have a skeletal Class III malocclusion, and to compare with those without asymmetry. We also performed a regional analysis of a possible correlation between facial soft- and hard-tissue asymmetries. METHODS: This retrospective study was performed with the use of the computed tomographic scans of 60 subjects. The skeletal Class III subjects were categorized into 2 subgroups: soft-tissue menton deviation ≤4 mm (n = 20) versus >4 mm (n = 20). The Class III groups were compared with a Class I symmetry group (n = 20). Hard and soft tissues were segmented into different morphologic areas and deviation calculated. Pearson correlation coefficients were obtained, and 1-way analysis of variance was conducted for statistical analysis. RESULTS: The highest deviation in the hard tissues of the Class III asymmetry group was in the corpus region (5.55 ± 3.05 mm), with the second highest in the angulus region (4.70 ± 2.43 mm). The highest average deviation in the soft tissues was seen in the lower cheek (7.04 ± 3.46 mm). In the different study groups, the amounts of asymmetry measured in anatomic structures on the mandible were found to be highly correlated between neighboring structures. CONCLUSIONS: Clinically and statistically significant differences were found in the anatomic regions located in the middle and lower thirds of the face. There was a medium or high correlation between condyle, coronoid process, ramus, and angulus regions. A low level of correlation was observed between middle face and mandibular asymmetries in hard-tissue upper cheek and lower cheek regions were correlated with different mandibular regions.

PURPOSE: To perform a multicenter prospective study of ultrasound prenasal thickness (PT), and nasal bone length (NBL) measurement at 11-14 weeks' gestation. METHODS: Ultrasound PT and NBL determination was performed in 504 normal fetuses and 17 fetuses with Down's syndrome (DS). Measurements were made from mid-sagittal 2D images acquired using a standardized technique during nuchal translucency (NT) examination. PT and NBL values were expressed in multiples of the gestation-specific normal median (MoM) and as the PT/NBL ratio. Information on PT and NBL MoMs was also combined using logistic regression. Results were classified as positive according to whether they were greater than the normal 95th centile for PT, PT/NBL and the DS risk from logistic regression equation or below the 5th centile for NBL. RESULTS: The median value in DS cases and unaffected controls were: PT 1.26 and 0.996 MoM; and NBL 0.596 and 0.993 MoM. The proportion of DS fetuses with positive results was 41% for PT, 65% for NBL, and 82% for both the PT/NBL ratio and DS risk from the logistic regression equation. PT/NBL levels did not vary according to gestational age. CONCLUSION: The PT/NBL ratio is a valuable first trimester DS screening marker that can be easily determined concomitant with the NT measurement.

Los hemangiomas cavernosos representan menos del 1% de todos los tumores óseos, siendo las vértebras y el cráneo las localizaciones más habituales. Estos tumores son extremadamente raros en los huesos de la nariz, con muy pocos casos publicados en la literatura médica, descritos en cornetes, vómer, huesos propios o lamina erpendicular del etmoides. Suelen presentarse como una lesión tumoral que crece con el tiempo, implicando al hueso e incluso a tejidos blandos, pudiendo causar complicaciones como obstrucción nasal, sangrado, ulceraciones e infección, entre otras. Presentamos el caso de un paciente de 37 años con un hemangioma cavernoso localizado en los huesos propios de la nariz, revisándose los aspectos más destacados de este raro tumor
Cavernous hemangiomas represent less than 1% of all bone tumours, with the vertebrae and the skull being the most common locations. These tumours are extremely rare in the bones of the nose, with very few cases published in the medical literature, where they have been reported in turbinates, vomer, nasal bones or perpendicular lamina of the ethmoid. They usually present as a tumour lesion that grows over time, involving the bone and even the soft tissues, which can cause complications such as nasal obstruction, bleeding, ulcerations and infection. We present the case of a 37 year old patient with a cavernous hemangioma located in the bones of the nose, reviewing the most notable aspects of this rare tumour

The purpose of this study was to compare fluctuating asymmetry (FA) levels across cranial modules of normal and pathological cranial specimens. It was examined whether pathological specimens have significantly higher FA scores than normal specimens in cranial regions affected by a developmental disorder. For this study, a modern Thai skeletal sample from Chulalongkorn University was analyzed. Ninety-two cranial landmarks were digitized on 66 adult and eight sub-adult normal specimens and on five pathological specimens including two adults with abnormal palates, two sub-adults with craniosynostosis, and one sub-adult with natal absence of nasal bones. In sub-adults, FA scores of specimens with developmental disorders were significantly higher than normal specimens in the entire cranium (pâ¯=â¯0.041) and vault (pâ¯=â¯0.025). However, comparisons excluding specimen with coronal craniosynostosis were not statistically significant. In adult specimens, comparisons of FA scores in each separate cranial module were also not statistically significant. These results suggest that elevated cranial FA may not be confined to the specific cranial region with the developmental disorder.

Craniosynostosis is caused by premature fusion of one or more cranial sutures, restricting skull, brain and face growth. Nonsyndromic craniosynostosis could disturb the proportions of face. Although morphometric diameters of nasal cavity in healthy children are already known, they have not been established yet in children with nonsyndromic craniosynostosis. The aim our study was to check whether diameters of bone structures of nasal cavity in children with nonsyndromic craniosynostosis measured in CT are within normal range. 249 children aged 0-36 months (96 with clinical diagnosis of nonsyndromic craniosynostosis and 153 in control group) were included into the study. The following diameters were measured on head CT scans: anterior bony width (ABW), bony choanal aperture width (BCAW), right and left posterior bony width (between bone sidewall and nasal cavity septum-RPBW and LPBW). The study group has been divided into 4 categories, depending on child's age. The dimensions measured between bone structures of nasal cavity were statistically significantly lower in comparison to the control group. They did not depend on the sex for ABW, nor on age in groups 7-12 months and < 2 years for BCAW, RPBW and LPBW. The measured dimensions increased with age. In children with nonsyndromic craniosynostosis the diameter of pyriform aperture and bony choanal aperture were lower than in controls, what may be described as fronto-orbital anomalies. Morphometric measurements of anthropometric indicators on CT scans could be used as standards in the clinical identification of craniosynostosis type and may help in planning surgical procedures, particularly in the facial skeleton in children.

BACKGROUND Lidocaine is widely used as a general and local anesthetic in minor or major surgeries. The objective of the study was to compare postoperative pain relief and adverse events using different forms of lidocaine administration in patients following closed nasal bone reduction surgery. MATERIAL AND METHODS A total of 381 patients with a solitary nasal fracture that could be managed with closed reduction were included in this study and divided into 3 groups of 127 patients in each group. Patients had received 1% lidocaine HCl with epinephrine (LL group), inserted a mesh impregnated with lidocaine spray (TL group), or 1 mg/kg/h lidocaine infusion (GL group) before surgeries. Patients also received morphine when the pain was not controlled. The postoperative pain was assessed at 6 hours and 48 hours after surgery. Postoperative vomiting and nausea were evaluated. Repeated ANOVA/Tukey-Kramer multiple comparisons test was performed at 95% confidence level. RESULTS At 6 hours after surgery, patients in the general lidocaine (GL) group reported decreased postoperative pain compared with those in the topical lidocaine (TL) group (P<0.001, q=6.633) and LL group (P<0.001, q=8.056). The morphine consumption within 48 hours was least in GL group than TL group (P<0.001, q=172.9) and LL group (P<0.001, q=226.42). Lidocaine infusion caused nausea (P<0.001, q=6.742) and vomiting (P<0.001, q=4.306). CONCLUSIONS Topical lidocaine anesthesia had the same postoperative pain relief and the least adverse events as local and general lidocaine anesthesia.

INTRODUCTION: The aim of this study was to evaluate the value of absent fetal nasal bone in the prediction of fetal chromosomal abnormalities, according to whether it was associated with other soft markers or structural abnormalities in a prescreened population of Chinese pregnant women. MATERIAL AND METHODS: In this retrospective cohort study, women whose fetuses had absent nasal bone detected during the second trimester ultrasound scan were followed. Fetal karyotyping was performed and pregnancy outcomes were recorded. The association between absent fetal nasal bone with abnormal karyotype was evaluated according to whether soft markers or structural abnormalities were also observed. RESULTS: Fetal nasal bone was assessed in 56 707 singleton pregnancies. After exclusion of unqualified cases, 71 (71/56 707, 0.13%) fetuses were included in the final analyses, of which 16 (16/71, 22.54%) were detected to have chromosomal abnormalities, including 12 cases of trisomy-21, three of trisomy-18, and one of micro-deletion (in 7q). Among the 42 cases with isolated absence of nasal bone, two had trisomy-21 and one had a micro-deletion. Absence of nasal bone in association with other structural abnormalities had a higher rate of abnormal karyotypes compared with isolated absence of nasal bone [83.33% (10/12) vs. 7.14% (3/42), Fisher's exact test χ2 = 25.620, p < 0.001]. CONCLUSION: Absent fetal nasal bone is a highly specific ultrasonographic soft marker that should be included in the routine second trimester ultrasound scan.

Atrophic rhinitis (AR) is a disease characterized by the extensive dilatation of the nasal cavity and atrophy of the mucosa, submucosa and bone tissue. Its etiological factors are unknown. There is not a satisfying treatment yet and the treatment of the functional impairment in the atrophic cells is still subject to investigation. The objective of this study is to determine at the histopathological level the possible effects of the submucosal fat injection in an experimental model of AR. 12 albino Wistar-Hannover male rats were included in the study. AR was induced with the Pasteurella multocida toxin, which was diluted with saline. As one of the rats died during the study, it was excluded from the evaluation. The right nasal cavities of all rats (11 nasal cavities) were defined as the control group (Group 1). Fat tissue obtained from the abdominal area was injected in the seven left nasal cavities (Group 2). All injections, which were done to the abdominal regions were also done in the left nasal cavities of the remaining four rats, which constituted the sham group (Group 3). After 14 days, all rats were decapitated and the squamous metaplasia and keratinization in the superficial epithelium, degeneration, vacuolar changes in the basal layer, congestion, inflammatory infiltration, vascular proliferation and glandular atrophy in the submucosa are histopathologically classified. The results were analyzed with statistical methods. Although glandular atrophy was significantly regressed in the fat injection group (Group 2) compared to other groups (p < 0.05), the remaining parameters did not show any significant difference among these three groups. The histopathological effect of the fat injection was modest. We concluded that fat injection treatment has no or at the most a very limited effect in the treatment of atrophic rhinitis.

Chondrodysplasia punctata is abnormal calcification in the cartilage of developing bones and has been seen in association with deranged vitamin K metabolism. Warfarin, an oral anticoagulant acting on vitamin K dependent clotting factors is known to cause chondrodysplasia punctata. Despite the knowledge of the condition the management of patients with prosthetic heart valves might require use of the drug for anticoagulation. Here, we present a case of a fetal warfarin syndrome in a second born child of a 27 year lady under warfarin for prosthetic heart valve. The pregnancy was complicated by polyhydramnios in third trimester and terminated at term by normal vaginal delivery. The baby was well, except for facial dysmorphism in the form of depressed nasal bridge, narrow nares and suspected left choanal atresia. Radiograph revealed stippled ephiphysis of vertebra, femora and humera supporting diagnosis of fetal warfarin syndrome. The baby did not develop any perinatal complication and was discharged home.

A 14-month-old Japanese Black heifer presented with unilateral epistaxis and mild swelling of the right face. Radiography revealed a mass with increased radiopacity on the right side of the nasal bridge, extending to the left side. Intranasal endoscopy confirmed a large tumor-like structure protruding into the nasal cavity. Following euthanasia, cranial computed tomography (CT) was performed, revealing a tumor 24.3 × 17.5 × 14.8 cm in size. The tumor occupied the entire right nasal cavity and the frontal and sphenoid sinuses. Histopathological examination revealed that the tumor consisted of well-differentiated trabecular bones and loose connective tissue. Based on these findings, a diagnosis of osteoma was established. This report describes a case of osteoma with an acute course in a Japanese Black heifer.
