The healing potential of fat grafting was empirically noted by the surgeons who were confronted with the dramatic facial disfigurements resulting from World War 1. Fat was transplanted into the wounds either en bloc or in parcels to promote the healing capacity or to correct the uneven, depressed scars from gunshot wounds, enabling the poor soldiers to step back to society and families in a shorter period of time.The idea of transplanting fat into the wound of the facially disfigured started with Hippolyte Morestin (1869-1919), surgeon in chief at Val-de Grace Military Hospital in Paris and was widely adopted by HD Gillies (1882-1960), Erich Lexer (1867-1937), Gustavo Sanvenero Rosselli (1897-1974), and others, achieving amazing results. Successful treatment of facially injured individuals showed the importance of plastic surgical procedures, the social role of the discipline, basis for obtaining the official recognition as surgical specialty.

Most craniofacial malformations are identified by their appearance. The majority of the classification systems are mainly clinical or anatomical, not related to the different levels of development of the malformation, and underlying pathology is usually not taken into consideration. In 1976, Tessier first emphasized the relationship between soft tissues and the underlying bone stating that "a fissure of the soft tissue corresponds, as a general rule, with a cleft of the bony structure". He introduced a cleft numbering system around the orbit from 0 to 14 depending on its relationship to the zero line (ie, the vertical midline cleft of the face). The classification, easy to understand, became widely accepted because the recording of the malformations was simple and communication between observers facilitated. It represented a great breakthrough in identifying craniofacial malformations, named clefts by him. In the present paper, the embryological-based classification of craniofacial malformations, proposed in 1983 and in 1990 by us, has been revisited. Its aim was to clarify some unanswered questions regarding apparently atypical or bizarre anomalies and to establish as much as possible the moment when this event occurred. In our opinion, this classification system may well integrate the one proposed by Tessier and tries at the same time to find a correlation between clinical observation and morphogenesis.Terminology is important. The overused term cleft should be reserved to true clefts only, developed from disturbances in the union of the embryonic facial processes, between the lateronasal and maxillary process (or oro-naso-ocular cleft); between the medionasal and maxillary process (or cleft of the lip); between the maxillary processes (or cleft of the palate); and between the maxillary and mandibular process (or macrostomia).For the other types of defects, derived from alteration of bone production centers, the word dysplasia should be used instead. Facial dysplasias have been ranged in a helix form and named after the site of the developmental arrest. Thus, an internasal, nasal, nasomaxillary, maxillary and malar dysplasia, depending on the involved area, have been identified.The classification may provide a useful guide in better understanding the morphogenesis of rare craniofacial malformations.

Background: Tracheotomy is a life-saving operation but may have bothersome sequelae. Because the defect resulting from tracheostomy is often allowed to repair spontaneously by secondary intention, hypertrophic scar formation is a frequent consequence. Furthermore, skin-to-trachea adhesions may develop, creating a "tracheal tug," that is, the skin movement in conjunction with the trachea, causing discomfort on swallowing. The aim of this study was to verify whether lipofilling could treat the aesthetic and functional disturbances by remodeling tracheostomy scars., Methods: Ten patients, aged 20 to 51 years, with retracted and/or hypertrophic tracheostomy scar underwent fat injection under local anesthesia or sedation. Fat harvesting was by a 2-mm blunt cannula connected to a 10-mL syringe. Before inserting the refined fat with a 19-gauge cannula, the fibrotic bands of the retracted scar between skin and underlying tissue were released with a sharp needle. The procedure required 2 sessions with an interval of 6 to 12 months. In the first session, 3.0 to 10 mL of fat were inserted. A further 3 to 5 mL were delivered during the second course. In 3 cases, scar excision was performed under local anesthesia as a final procedure., Results: All 10 patients achieved an aesthetic and functional improvement and were satisfied with the result at long-term follow-up (mean, 21.3 months)., Conclusions: Fat grafting proved to be a safe, minimally invasive, and effective procedure for the treatment of the tracheostomy scar both for functional and aesthetic purposes. It can be considered as a valid alternative to major open surgery.

The aim of this article was to describe the technical details of a fat injection procedure for the treatment of mild to moderate velopharyngeal insufficiency (VPI). Before surgery, the velopharyngeal gap is assessed by means of flexible nasoendoscopy, and speech intelligibility, hypernasality, and nasal air escape are perceptually evaluated and scored by independent raters; nasal airflow during speech is objectively measured. The lipoaspirate is centrifuged at 1200g for 3 minutes to separate and remove blood, cell debris, and the oily layer. Patients are injected with 3.5 to 8 mL of fat in the posterior and lateral pharyngeal walls and soft palate under general anesthesia. The fat is placed within the superior constrictor muscle on the posterior pharyngeal wall to avoid injection behind the prevertebral fascia and possible intraoperative or postoperative fat displacement in a caudal direction. A 19-gauge malleable, blunt, single-hole cannula is used for fat grafting, and the operative field is exposed by means of a Digman mouth gag. Two Nelaton probes are inserted through the nostrils and retracted from the mouth under moderate tension to favor visualization of the nasopharynx. No donor-site or injection-site morbidity has been observed so far, and the 12 patients (aged 5-48 y) treated so far have not manifested snoring or nasal obstruction at any time after surgery. Improved voice resonance is audible soon after the operation, and no hyponasality can be detected. The patients are discharged the day after surgery. Subsequent fat grafting procedures can be performed to achieve further improvement. Correctly performed fat injections improve voice resonance and reduce nasal air escape in VPI, as demonstrated by nasoendoscopy, speech perceptual evaluation, and the objective measurement of nasal airflow and represent an alternative to velopharyngoplasty for mild to moderate VPI.

Jacopo Berengario was born in Carpi, a medieval city close to Modena (northern Italy), circa 1460. He studied medicine at Bologna University and, in 1489, graduated in philosophy and medicine. He was appointed lecturer in anatomy and surgery at the same university, a position that he maintained for 24 years. Between 1514 and 1523, Berengario published some important anatomic and surgical works, which gave considerable fame to him.Commentaria... supra Anatomiam Mundini (Commentary... on the Anatomy of Mondino), published in 1521, constitutes the first example of an illustrated anatomic textbook ever printed. The anatomic illustrations were intended for explaining the text. Artistically speaking, the plates are typical examples of the Renaissance period and worthy of the greatest consideration.De Fractura Calvae sive Cranei (On Fracture of the Calvaria or Cranium), published in Bologna in 1518, is the first treatise devoted to head injuries ever printed. It is a landmark in the development of cranial surgery that went through numerous editions. The text was prepared in 2 months and dedicated to Lorenzo de' Medici, Duke of Urbino, who experienced a skull injury in the occipital region. Berengario wanted to demonstrate to other physicians his knowledge of anatomy and his expertise on the brain and head traumas. The book includes the illustration of an entire surgical kit or a corpus instrumentorum for performing cranial operations, which appeared for the first time in a printed book. However, Berengario's highly commendable aim was to indicate to the reader the step-by-step procedure of craniotomy for management of skull fractures along with the sequential use of the previously presented instruments.
