    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

    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

    Full text link
    “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
