Abstract
Diprosopus is a congenital anomaly in which partial or complete duplication of craniofacial structures occurs. Because it is rare, the mortality rate is high, and information concerning this anomaly is scarce. This study describes a case of human diprosopus in a 9-year-old male individual, who has severe complications associated with the central nervous, cardiovascular, respiratory, and digestive systems. Since birth, he has been monitored in a specialized hospital environment, where he has undergone several surgeries and multidisciplinary treatments. Regarding the craniofacial aspects, he had agenesis of the corpus callosum, floor of the nasal cavity, and floor of the anterior cranial fossa, in addition to the presence of bone dysplasia, ocular hypertelorism and cleft palate with nasal and oral teratoma. Regarding dental characteristics, the patient has duplication of the maxilla, mandible, tongue, and some teeth. After complementary imaging exams, several supernumerary teeth were found, with some being impacted and in complex regions, with an indication for extraction due to the risks of impaction, irruptive deviation, root resorption, and associated cystic or tumoral lesions. Because of the numerous complications, knowledge, and preparation of the entire team is necessary for the correct management of the case.

Abstract
OBJECTIVE To fix a gray zone left in Tessier's classification of rare clefts with cleft 6 and to give a more comprehensive description of cleft 6 anatomy. DESIGN The material used for the research was a series of 26 clinical cases of patients with assessed cleft 6 and 44 cases found out of a literature review with enough data to be useful. The 70 cases were cross-examined by the authors. STUDY SETTING The authors are senior craniofacial surgeons working in high-case load department from university centers where the patients are documented and receive primary as well as secondary treatment and follow-up. PATIENTS The patients were selected out of the series of craniofacial deformities taken care of by the authors' department as rare clefts. MAIN OUTCOME We describe the full spectrum of cleft 6 as an autonomous entity that could present itself in three subtypes: 6a is the most proximal and could be associated with cleft 8. The subtype 6b is medial toward the zygomatic arch and frequently associated with a bone and teeth appendage (frequently described as a "maxillary duplication"). The subtype 6C goes toward the external ear between the helix crus and the auditory meatus. CONCLUSIONS The Tessier's opinion is that Treacher Collins syndrome was the association of clefts 6, 7, and 8 and is no longer sustainable in the light of modern genetics. Most of the cleft 6 are misdiagnosed in the literature.

Abstract
Craniofacial duplication is a rare congenital anomaly. A case of hemi-mandibular duplication with an accessory oral cavity is presented with along with first-time reported pre- and postnatal MRI, surgical approach and a literature review. MRI clearly depicts the ectopic tooth buds and parotid aplasia in this condition, features that are diagnostic of partial facial duplication. MRI is diagnostic for this condition and can be useful to avoid misdiagnosis of a facial mass.

Abstract
A newborn girl was referred to the otolaryngology service after prenatal imaging showed a right mandibular mass. Physical examination revealed a 1-2 cm mass along the right mandible with the appearance of a vestigial oral cavity. Tissue resembling the vermillion and primitive tongue appeared innervated and moved in conjunction with oral movements. MRI and CT of the mandible after birth confirmed a partially ossified soft tissue mass of the right mandibular body, containing unerupted teeth. She was taken to the operating room at 6 months of age for mass excision and reconstruction. Postoperatively, she healed well and was feeding without difficulty. Craniofacial duplication, including duplication of stomatodeal structures or diprosopus, is a rare condition with a variety of phenotypes. In the case of suspected craniofacial duplication, associated syndromes should be ruled out and appropriate imaging employed to determine the extent of involvement of adjacent structures, which will ultimately guide surgical planning.

Abstract
Since its initial discovery in a Drosophila mutagenesis screen, the Hedgehog pathway has been revealed to be instrumental in the proper development of the vertebrate face. Vertebrates possess three hedgehog paralogs: Sonic hedgehog (Shh), Indian hedgehog (Ihh), and Desert hedgehog (Dhh). Of the three, Shh has the broadest range of functions both in the face and elsewhere in the embryo, while Ihh and Dhh play more limited roles. The Hedgehog pathway is instrumental from the period of prechordal plate formation early in the embryo, until the fusion of the lip and secondary palate, which complete the major patterning events of the face. Disruption of Hedgehog signaling results in an array of developmental disorders in the face, ranging from minor alterations in the distance between the eyes to more serious conditions such as severe clefting of the lip and palate. Despite its critical role, Hedgehog signaling seems to be disrupted through a number of mechanisms that may either be direct, as in mutation of a downstream target of the Hedgehog ligand, or indirect, such as mutation in a ciliary protein that is otherwise seemingly unrelated to the Hedgehog pathway. A number of teratogens such as alcohol, statins and steroidal alkaloids also disrupt key aspects of Hedgehog signal transduction, leading to developmental defects that are similar, if not identical, to those of Hedgehog pathway mutations. The aim of this review is to highlight the variety of roles that Hedgehog signaling plays in developmental disorders of the vertebrate face.

Abstract
OBJECTIVE This study aims to present the pattern and management of atypical facial clefts from a Nigerian population. DESIGN This is a retrospective study of patients seen during series of surgical outreach programs in North Central Nigeria, between 2011 and 2017. All cases of atypical facial clefts encountered were evaluated for the pattern of presentation using Tessier classification system. All of them were surgically repaired and outcome was determined using a Likert scale. Data were presented using descriptive statistics. SETTING Outreach programs in North Central Nigeria by Cleft & Facial Deformity Foundation. RESULTS Thirty-six patients, 19 (52.8%) males and 17 (47.2%) females, were studied. The age range was 1 week to 34 years, with mean (standard deviation) of 11.2 (11.8) years. Fifty-eight cleft cases were recorded, with Tessier 1 being the commonest (n = 14; 24.1%) cleft type. There were 35 (60.3%) cases of middle cleft, 14 (24.2%) cases of oblique cleft, and 9 (15.5%) cases of lateral cleft. Typical cleft lip and palate coexisted with atypical facial cleft in 2 (5.6%) patients. Cleft was found to be median in 12 (33.3%) patients and right sided in 9 (25%) patients. Majority (n = 24, 66.7%) of the cases were repaired by simple excision plus direct closure with successful outcome. CONCLUSIONS Numerical classification by Paul Tessier has reduced the inconsistencies of nomenclature among practitioners. Majority of atypical facial clefts could be treated by simple techniques with satisfactory outcomes. However, the more complex cases will require multistaged surgical approach.

Abstract
Background Diprosopus dirrhinus, or nasal duplication, is a rare entity of partial craniofacial duplication. Methods The case we present is the first report of diprosopus dirrhinus associated with complete cleft lip and palate. The baby was born in Cambodia at full term by normal vaginal delivery with no significant perinatal and family history. Physical examination revealed significant facial deformity due to the duplicated nose and the left complete cleft lip/palate on the right subset. Results There were 4 nostrils; both medial apertures including the cleft site were found to be 10-15 mm deep cul-de-sac structures without communication to the nasopharynx. The upper third of the face was notable for hypertelorism with a duplication of the soft-tissue nasion and glabella. Between the 2 nasal dorsums, there was a small cutaneous depression with a lacrimal fistula in the midline. Surgical treatment included the first stage of primary lip and nose repair and the second stage of palatoplasty. Conclusions The patient was followed up at the age of 10 years showing satisfactory results for both aesthetic and functional aspects. Further management in the future will be required for the hypertelorism and nasal deformity.

Abstract
As far as is known, this paper gives the first description of a two-headed shark embryo belonging to an oviparous species, Galeus atlanticus (Carcharhiniformes: Scyliorhinidae). The specimen was detected among 797 embryos intended for cardiovascular studies, which represents a defect incidence of 0·13%. Each head had a mouth, two eyes, a brain, a notochord and five gill openings on each side. The two heads fused behind the gills. On the single body, there were four anticipated dorsal fins, two anterior, right and left and two posterior, right and left. Ventrally, the specimen possessed two pairs of pectoral fins, a pair of pelvic fins and one anal fin. Two adjacent notochords, two neural tubes and two dorsal aortas ran along the body, which bent 180° at its posterior portion. There were two hearts, two oesophaguses, two stomachs, two livers, but a single intestine with a spiral valve. Previous reports of conjoined twins in sharks are scarce and only refer to oviparous and ovoviviparous species. Seven dicephalous sharks reported so far were similar to the specimen described here, namely, with two totally separated heads on one body. Instead, only one case of diprosopus shark has been reported; it had a single body and a single head with partial duplication of the face. Two further cases described in the literature as dicephalous or simply as abnormal sharks should be better regarded as diprosopus, while another three cases, also considered dicephalous, showed a mixture of characteristics of diprosopia and dicephalia.

Abstract
BACKGROUND Diprosopus is a subtype of symmetric conjoined twins with one head, facial duplication and a single trunk. Diprosopus is a very rare congenital anomaly. METHODS This is a systematic review of published cases and the presentation of two new cases born in Argentina. We estimated the prevalence of conjoined twins and diprosopus using data from the National Network of Congenital Anomalies of Argentina (RENAC). RESULTS The prevalence of conjoined twins in RENAC was 19 per 1,000,000 births (95% confidence interval, 12-29). Diprosopus prevalence was 2 per 1,000,000 births (95% confidence interval, 0.2-6.8). In the systematic review, we identified 31 diprosopus cases. The facial structures more frequently duplicated were nose and eyes. Most frequent associated anomalies were: anencephaly, duplication of cerebral hemispheres, craniorachischisis, oral clefts, spinal abnormalities, congenital heart defects, diaphragmatic hernia, thoracic and/or abdominal visceral laterality anomalies. One of the RENAC cases and three cases from the literature had another discordant nonmalformed twin. CONCLUSION The conjoined twins prevalence was similar to other studies. The prevalence of diprosopus was higher. The etiology is still unknown. The presence of visceral laterality anomalies may indicate the link between diprosopus and the alteration or duplication of the primitive node in the perigastrulation period (12-15 days postfertilization). Pregnancies of more than two embryos may be a risk factor for diprosopus. Given the low prevalence of this defect, it would be useful to perform studies involving several surveillance systems and international consortiums.

Abstract
INTRODUCTION Diprosopus, or partial facial duplication, is a very rare congenital abnormality. It is a rare form of conjoined twins. Partial facial duplication may be symmetric or not and may involve the nose, the maxilla, the mandible, the palate, the tongue and the mouth. OBSERVATION A male newborn springing from inbred parents was admitted at his first day of life for facial deformity. He presented with hypertelorism, 2 eyes, a tendency to nose duplication (flatted large nose, 2 columellae, 2 lateral nostrils separated in the midline by a third deformed hole), two mouths and a duplicated maxilla. Laboratory tests were normal. The cranio-facial CT confirmed the maxillary duplication. DISCUSSION This type of cranio-facial duplication is a rare entity with about 35 reported cases in the literature. Our patient was similar to a rare case of living diprosopus reported by Stiehm in 1972. Diprosopus is often associated with abnormalities of the gastrointestinal tract, the central nervous system, the cardiovascular and respiratory systems and with a high incidence of cleft lip and palate. Surgical treatment consists in the resection of the duplicated components.

Abstract
A wide variety of congenital nasal lesions can present to clinical attention due to airway obstruction, the presence of a mass, and/or cosmetic deformity, including pyriform aperture stenosis, choanal atresia, nasopharyngeal atresia, arrhinia, congenital germline fusion cysts, cephaloceles, neuroglial heterotopia, nasolacrimal duct mucoceles, hamartomas, supernumerary nostril, and bifid nose. Computed tomography and magnetic resonance imaging, which are the main imaging modalities used to characterize these lesions, often serve complementary roles. Familiarity with embryology and anatomy is also essential for recognizing the diagnostic imaging findings related to congenital nasal lesions.

Neural crest cell signaling pathways critical to cranial bone development and pathology. Exp Cell Res 2014; 325:138-47.

Abstract
Neural crest cells appear early during embryogenesis and give rise to many structures in the mature adult. In particular, a specific population of neural crest cells migrates to and populates developing cranial tissues. The ensuing differentiation of these cells via individual complex and often intersecting signaling pathways is indispensible to growth and development of the craniofacial complex. Much research has been devoted to this area of development with particular emphasis on cell signaling events required for physiologic development. Understanding such mechanisms will allow researchers to investigate ways in which they can be exploited in order to treat a multitude of diseases affecting the craniofacial complex. Knowing how these multipotent cells are driven towards distinct fates could, in due course, allow patients to receive regenerative therapies for tissues lost to a variety of pathologies. In order to realize this goal, nucleotide sequencing advances allowing snapshots of entire genomes and exomes are being utilized to identify molecular entities associated with disease states. Once identified, these entities can be validated for biological significance with other methods. A crucial next step is the integration of knowledge gleaned from observations in disease states with normal physiology to generate an explanatory model for craniofacial development. This review seeks to provide a current view of the landscape on cell signaling and fate determination of the neural crest and to provide possible avenues of approach for future research.
