Percutaneous approach to isolated zygomatic arch fractures. Personal experience
Aim. The authors present their experience gained from the reduction of zygomatic arch fractures by means of the closed percutaneous reduction technique.
Methods. During the period January 1994 - December 2002, 293 patients with fractures of the orbito-maxillo-malar complex were treated, of which 45 were isolated fractures of the zygomatic arch. Patients with this type of fracture underwent surgery under local anaesthesia, which was performed by means of the closed percutaneous reduction technique through the sub-zygomatic way, according to the technique described by Fiamminghi.
Results. From the total of 45 patients treated by means of this technique only 2 complications were experienced (4.45%); incomplete reduction in one instance and sialoadenitis of the parotid gland in the other.
Conclusion. Comparing this easy, swift and low-cost method to other more expensive and complex techniques, which also call for a general anaesthesia, this procedure is recommended as a first choice for isolated zygomatic arch fractures

Function of the sensate free forearm flap after partial glossectomy
AIMS: To compare functional recovery of sensitive free forearm flaps with non-sensitive free forearm flaps, following reconstruction for partial glossectomy. MATERIAL: Sixteen patients underwent partial glossectomy for oncological reasons, of whom: nine patients underwent repair with non-sensitive free forearm flaps (group A) and seven with sensitive free flaps (group B). METHODS: All patients underwent the following tests: (1) tactile sensitivity evaluation, localization of stimulus, sharp/blunt definition, discrimination between two points (static and dynamic), thermal sensitivity to heat/cold; (2) speech evaluation by means of the modified Fanzago test; (3) subjective evaluation concerning the degree of satisfaction of the following functions: swallowing, feeding and talking. RESULTS: The sensitivity and logopaedic evaluation tests and the subjective evaluation charts highlight an overall better functional recovery of the sensitive repair than the non-sensitive ones. CONCLUSION: In patients who have undergone partial glossectomy repair with free forearm neurofasciocutaneous flaps allow good recovery of oral functions and, therefore, a good quality of life
Vertical increase in mandibular reconstructive surgery with fibula flap : double barrel and osteogenetic distraction
Aim. The free fibula flap is today considered the gold standard for mandibular reconstructions, and provides an adequate length of bone of the correct consistency for this procedure. The disadvantage is the lack of thickness, which does not offer an adequate vertical dimension for the newly constructed mandible, in particular when the procedure must be followed by osseointegrated tooth implants. Two methods have been developed to increase the vertical dimension of the new mandible: the double-barrel method and osteogenetic distraction.
Methods. Between April 1995 and October 2003 at the Division of Maxillofacial Surgery, San Paulo Hospital, Milan, 63 fibula free flaps were positioned; 17 were at the maxilla and 46 at the mandible.
Results. Among the mandibular reconstructions, in 4 cases the double-barrel technique was applied, with the intent of optimising the vertical dimension of the reconstructed mandible. In 2 cases in which the double-barrel technique could not be applied, osteogenetic distraction was performed on the new mandible in order to achieve a vertical increase in the various bone sectors.
Conclusion. Application of these techniques made it possible to achieve adequate bone thickness in the new mandible, so as to optimise future prosthetic rehabilitation of the tooth arch
Use of free flaps in maxillofacial surgery. A review of 200 clinical cases
Aim. Microvascular flaps are today a fundamental reconstruction technique in the field of maxillofacial surgery thanks to their high reliability and the availability of different tissues in terms of quality and quantity.
Methods. The results obtained in 200 micro-surgical reconstruction procedures of the head and face are analysed. Reconstruction followed cancer ablation in 159 cases, and was due to facial paralysis, limited mouth opening, osteoradionecrosis or severe maxillary atrophy in the remaining 41 cases. Flaps used were: fibula (73 cases), fascia-cutaneous component of forearm (75 cases), rectus abdominis muscle (13 cases), latissimus dorsi muscle (28 cases), iliac crest (7 cases), parascapular system (2 cases) omentum (1 case), lateral brachialis (1 case). Postoperative monitoring comprised both clinical examination and Doppler scanning; 48 completely concealed flaps were monitored by Doppler scanning alone.
Results. The success rate was 95.5%. In 14 cases, surgical re-exploration of the flap was required for vascular insufficiency; 78% of these flaps were saved. Neither prior surgical intervention, nor prior irradiation of the surgical field, nor the presence of metabolic diseases negatively influenced the success rate.
Conclusion. The low rates of failure and complications, together with the good results in morphological and functional terms, make microvascular flaps one of the most significant reconstruction methods for the oral and maxillofacial area, in particular for extensive defects

Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Variations on the Author
“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
