The role of balloon sinuplasty in the treatment of sinus headache
No full textIntroduction: Headache attributed to rhinosinusitis, commonly called sinus headache (SH), is probably one of the most prevalent secondary headaches. The purpose of our study was to examine further sinus headache comparing the effect of conventional functional endoscopic sinus surgery and the balloon sinuplasty. Material and methods: Eighty-three consecutive patients were enrolled from 2009 to 2012, who were diagnosed sinus headache according the diagnostic criteria of AAO-HNS and of HIS. 40 patients were randomized to Conventional Endoscopy Sinus Surgery for frontal sinus (ESS Group), 35 to balloon sinuplasty of frontal sinus (BS Group). Results: The mean operative time was 65 ± 15 min for ESS group patients and 32 ± 7 min for 23 patients (BS1 Group) and 55 ± 18 min for 12 treated with hybrid technique (BS2 Group). The preoperative mean of SNOT-22 scores improved from 28.6 ± 1.2 in ESS group and 27.3 ± 0.8 in BS group to a 1-month postoperative scores of 14.5 ± 0.6 in ESS group and 10.3 ± 0.5 in BS group and to a 6-month postoperative scores of 7.8 ± 0.6 and 5.3 ± 0.3, respectively (p < 0.0001). The headache scores base on analog visual scale improved from a preoperative mean of 6.5 ± 0.3 in ESS group and 7.1 ± 0.4 in Bs group to a 1-month postoperative scores of 5.4 ± 0.4 in ESS group and 5.5 ± 0.4 in BS group and to a 6-month postoperative scores of 2.7 ± 0.5 and 1.2 ± 0.1, respectively, representing a statistically significant reduction in headache score in both group. Conclusion: Our data prove that improvement in headache can be expected in patients treated with balloon catheter. © 2013 Polish Otorhinolaryngology - Head and Neck Surgery Society
Experience in the Management of Frontal Sinus Fractures
No full textInternational guidelines for frontal sinus fractures, dealing with the indication Of Surgical treatment, obliteration of the frontal sinus, drainage, and cranialization, may differ. In this work, we describe our experience with frontal traumas, analyzing indications, type of treatment, and outcomes by reviewing all data of 112 patients treated for frontal fractures at the Department of Maxillo-Facial Surgery, Universita degli studi di Roma Sapienza. We reviewed all clinical and surgical records of patients with traumatic frontal injury treated from 1997 to September 2008, Patients presenting displaced fractures of the anterior wall of the frontal sinus were treated through skin laceration, if existing, or through a coronal approach and fixed with rigid internal devices. Patients with fracture of the posterior wall of the frontal sinus underwent frontal sinus cranialization with galea pericranium pedicled flap to prevent eventful septic complications. Follow-up controls documented that 98 of 112 patients showed no neurologic impairment, no symptoms of cerebrospinal fluid leak, and no other complications after 6 months and I and 5 years when follow-up was possible. In the international literature, there is wide agreement about indications dealing with displaced fractures of the anterior wall, although there is a lively debate about posterior wall treatment. In Our 10-year experience, the protocol we carried out showed satisfying outcomes, in particular, on the morphofunctional recovery and aesthetic results
Variations of the gonial angle in vertical surgical reduction of the maxillary-mandibular complex
No full textFrom an esthetic point of view, the mandibular or gonial angle plays an important role in ensuring a harmonious facial profile. The purpose of this study was to analyze the values of the mandibular angle in relation to variations of the vertical and sagittal positions of the jaw. The study was carried out on a sample of 42 patients who underwent surgery for maxillary-mandibular repositioning, advancing or raising the jaw, after a Le Fort I osteotomy and bilateral sagittal osteotomy of the jaw according to the technique described by Obwegeser-Dal Pont. In all patients, the maxillary bone was raised with a discrepancy of at least 3 mm between the anterior and posterior portions (favoring the latter) as a result of (clockwise) rotation of the bispinal plane. The data, obtained by means of cephalometric analysis according to the method of Ricketts, showed how changes in the gonial angle differed between patients who require correction of an open-bite and those who do not. In particular, in patients without an open-bite, advancement of the maxilla limited the opening of the angle. Similarly, in patients with an open-bite, the tendency to form an open gonial angle can usually be corrected by the association of advancement of the maxilla whenever possible
Tudor Translation in Theory and Practice
No full textFilling a gap in the study of early modern literature, Massimiliano Morini here exhaustively examines the aims, strategies, practice and theoretical ideas of the sixteenth-century translator. Morini analyzes early modern English translations of works by French and Italian essayists and poets, including Montaigne, Castiglione, Ariosto and Tasso, and of works by classical writers such as Virgil and Petrarch. In the process, he demonstrates how connected translation is with other cultural and literary issues: women as writers, literary relations between Italy and England, the nature of the author, and changes in the English language. Since English Tudor writers, unlike their Italian contemporaries, did not write theoretical treatises, the author works empirically to extrapolate the theory that informs the practice of Tudor translation - he deduces several cogent theoretical principles from the metaphors and figures of speech used by translators to describe translation. Employing a good blend of theory and practice, the author presents the Tudor period as a crucial transitional moment in the history of translation, from the medieval tradition (which in secular literature often entailed radical departure from the original) to the more subtle modern tradition (which prizes the invisibility of the translator and fluency of the translated text). Morini points out that this is also a period during which ideas about language and about the position of England on the political and cultural map of Europe undergo dramatic change, and he convincingly argues that the practice of translation changes as new humanistic methods are adapted to the needs of a country that is expanding its empire
Fronto-orbital mucoceles: our experience
No full textFrontal sinus mucoceles are rare benign neoplasms that can result in bony erosion extending from the borders of the sinus into the orbital cavity. The authors report the fronto-orbital mucoceles they have observed in the last 8 years. The authors used an "open surgery" approach in 12 fronto-orbital mucoceles, characterized by an osteoplastic frontal flap, through a coronal incision or Lynch incision. In this way, they were able to expose the frontal sinus and to remove completely the mucocele from the periorbita. Only one recurrence is reported 2 years after surgery. Excellent aesthetic results have been reached in all cases. In the literature, many different positions are reported for the treatment of mucoceles. The endoscopic surgery of the paranasal sinuses has become the procedure of choice for mucoceles of maxillary, ethmoidal, and sphenoidal sinuses. However, few authors have recommended the endoscopic approach for frontal mucoceles. The indications and limitations of endoscopic and "open" surgery are critically discussed in the light of the authors' personal experience and current literature
Early secondary alveoloplasty in cleft lip and palate
No full textThe aims of this study were to present a personal surgical technique throughout the review of international literature concerning surgical techniques, objectives, and outcomes in early secondary alveoloplasty and to describe our personal surgical techniques in alveolar bone defect repair in cleft lip and palate. Throughout a literature analysis, it is now settled that early secondary alveoloplasty could reestablish the continuity of alveolar bone and prevent upper dental arch collapse after presurgical orthopedic upper maxilla expansion; it also might give a good bone support for teeth facing the cleft and allow the eruption of permanent elements with the bone graft and rebalance the symmetry of dental arch, improve facial aesthetic, guarantee an adequate amount of bone tissue for a further prosthetic reconstruction with implant, and finally close the eventual oronasal fistula. The surgical technique we are presenting permitted a total number of 35 early secondary alveoloplasty on which a long-term follow-up is still taking place. We can assess that early secondary alveoloplasty must be performed before permanent canine eruption. Iliac crest is the suggested donor site for bone grafting; orthopedic and orthodontic treatments must be performed in association with surgery, and if there is the dental element agenesia, an implantation treatment must be considered
Three-Dimensional Temporomandibular Joint Modeling and Animation
No full textThe three-dimensional (3D) temporomandibular joint (TMJ) model derives from a study of the cranium by 3D virtual reality and mandibular function animation. The starting point of the project is high-fidelity digital acquisition of a human dry skull. The cooperation between the maxillofacial surgeon and the cartoonist enables the reconstruction of the fibroconnective components of the TMJ that are the keystone for comprehension of the anatomic and functional features of the mandible. The skeletal model is customized with the apposition of the temporomandibular ligament, the articular disk, the retrodiskal tissue, and the medial and the lateral ligament of the disk. The simulation of TMJ movement is the result of the integration of up-to-date data on the biomechanical restrictions. The 3D TMJ model is an easy-to-use application that may be run on a personal computer for the study of the TMJ and its biomechanics
Preliminary Findings from Our Experience in Anterior Palatoplasty for the Treatment of Obstructive Sleep Apnea
No full textObjectivesObstructive sleep apnea (OSA) is a common disorder affecting at least 2% to 4% of adult population characterized by the collapse of the pharyngeal airway. It is well established that retropalatal region is the most common site of obstruction. Consequently, many surgical techniques have been introduced. The purpose of this study is to present our preliminary results in the anterior palatoplasty (AP) compared with results of uvulopalatal flap (UPF).MethodsThirty-eight consecutive patients with mild-moderate OSA were prospectively enrolled into a randomised surgical protocol. Surgical success was measured primarily by satisfactory reduction in snoring, as reported by snoring assessment questionnaire (SQ) of sleep partners. Secondary outcomes measures included improvement in the Epworth Sleepiness Scale (ESS) scores, changes in the magnitude of pharyngeal collapse, and postoperative pain intensity.ResultsThe ESS after AP improved from a preoperative value 8.5±3.7 to a postoperative mean of 4.9±3.2 (P<0.001) after UPF improved from a preoperative value of 8.1±3.5 to 5.2±3.2 postoperatively (P<0.001). The results of satisfactory reduction in the volume of snoring and response at polysomnographic data were also similar in both procedures. We reported a statistically significant difference of the collapse noted at Müller manoeuvre that improved from 2.7±1.0 on average, to 1.1±0.9 (P<0.001) after AP and with a lesser extent, (from 2.8±1.1 on average to 1.8±1.1; P<0.05), after UPF. The mean duration of pain was 10.8 days for UPF patients and 7.1 days for AP patients. The mean pain score in the first 3 days, was 6.8 in UPF patients and 5.1 in AP patients.ConclusionThe subjective and objective improvements evidenced may suggest how AP is far superior to other techniques aimed at creating a palatal fibrotic scar. In the light of these results we can suggest AP procedure as more practical and comfortable when compared to UPF
The Faunæ Ligusticæ Fragmenta of Massimiliano Spinola (1805).
No full textDie Faunæ Ligusticæ Fragmenta, Decas Prima, 1805, waren der erste und einzige gedruckte Teil eines geplanten Werkes über die Insekten Liguriens. Er wurde auf Kosten seines Autors Massimiliano Spinola gedruckt. Soweit bekannt ist, blieb nur eine Kopie erhalten, da sein Autor kurzerhand und mit beinahe vollem Erfolg versuchte, ihn zu unterdrücken. Ob die Faunæ damit als valid publiziert gelten müssen oder nicht, wird diskutiert. Hier wird begründet, daß die Faunæ im strengen Sinne der Internationalen Regeln für die Zoologische Nomenklatur nicht gültig veröffentlicht worden sind und daß die wenigen Taxa, alle Hymenoptera, die darin beschrieben sind, mit den Namen bezeichnet werden sollten, einige etwas verändert, unter denen sie in den Insectorum Liguriæ, Bd. I, 1806, des gleichen Autors erstmals gültig publiziert wurden.StichwörterBibliography, Italy, Insecta, Hymenoptera.The Faunæ Ligusticæ Fragmenta, Decas Prima, 1805, was the first and only part to be printed of a projected work on the insects of Liguria. It was printed at the expense of its author, Massimiliano Spinola, and, so far as is known, only one copy survives, this primarily for the reason that its author shortly, and almost entirely successfully, sought to suppress it. Whether the Faunæ was or was not validly published has been disputed. It is argued here that the Faunæ was not validly published within a strict reading of the International Code of Zoological Nomenclature, and that the few taxa, all Hymenoptera, described in it should be known by the names, some altered, under which they were first validly published in the same author\u27s Insectorum Liguriæ, volume I, 1806.KeywordsBibliography, Italy, Insecta, Hymenoptera
Igor Stravinsky's 'The Flood' in Between Theatre and Television
No full textThe essay deals with the television production of The Flood (1962) one of the most significant compositions of Igor Stravinsky’s late output. The process that led from the original plans of Robert Craft, Stravinsky and George Balanchine to the final television production is read in the light of the remediation and mediatization processes, and of a dialectic between different kinds of visual-gestural representation, based on theatrical conventions. The author applies a multimedia approach. The musical component is examined with regard to both its connection to the visual aspects and its serial construction. The author shows how Stravinsky creates a musical equivalent of the opposite kinds of visual/gestural representation by diversified vocal characterizations of the roles and by a particular use of the diatonicism-chromaticism opposition
