Managing the severe septal deviation using dorsal preservation
No full text: Severe septal deviations are a constant challenge for rhinosurgeons. As the septum is the most important pillar of the nasal framework, septal deformities require correction to insure a straight nose. The septum should be on the midline without any tension to ensure a correct healing of the external nasal pyramid. In certain cases, the association of a correct septoplasty and dorsal preservation allows the treatment of the crooked nose and at the same time gives natural results with rapid postoperative recovery. The aim of this article was to underline the versatility of the dorsal preservation technique for the correction of severe septal deviation

Pisa Tower Concept and swinging door septoplasty: a winning combination in the most complex dorso-septal deviation
No full textThe crooked nose – that is, the deviation of the nasal pyramid from the median line of the frontal plane – is a constant challenge for rhinosurgeons.
The types of dorsal deviation can be many and often also involve the nasal tip. There are multiple causes of the deviation of the nasal pyramid and include, in the first instance, traumas, followed by iatrogenic or congenital factors.
All faces present an asymmetry but most people do not notice this if it is less than 3-4 mm.
However, it is very important to show the patient their facial asymmetry before performing the operation since the level of attention to each little detail will in- crease the post-operative period.
A careful analysis becomes essential for planning the operation. Each of the ana- tomical components (upper lateral cartilages and alars, the septum, the osseous vault, the nasal spine, the soft tissues and the ligament must be assessed since each can contribute to creating this deformity.
Even though, in structured rhinoplasty, various nasal osteotomy techniques have been described for the correction of osseous nasal deformities, so far surgical strategies have not been described that would be compatible with the dorsal pres- ervation philosophy.
The three main pillars of the dorsum are made up of the nasal bones (in conjunc- tion with the upright branch of the maxillary bone) and the nasal septum. There- fore, the correction of a crooked pyramid must involve the evaluation and, where necessary, management of one or more pillars
A 3-level impaction technique for dorsal reshaping and reduction without dorsal soft tissue envelope dissection
No full textBackground: Preservation Rhinoplasty (PR) techniques are continuously evolving in the last two years. Many variations of old-fashioned techniques have been proposed since Daniel coined this term in 2018.
Objectives: Authors want to describe indications for a new "three level impactions" technique allowing, in selected cases, a complete profile correction and dorsal reduction without the dorsal soft tissue envelope (STE) dissection.
Methods: Three hundred fifty primary closed rhinoplasty cases were retrospectively studied from January 2018 and October 2019. Age, sex, race and technical details, surgical time and complications have been registered. Ninety-five dorsums were reduced and shaped without dissecting the dorsal soft tissue envelope, combining a 1) swinging door septoplasty with low septal strip resection, 2) endonasal bony cap mosaic osteotomies, and 3) Let down or Push down operation (LDO/PDO).
Results: All patients showed a dramatic change in profile height and shape without neither dorsal STE dissection nor bony cartilage dorsal tissue resection. The average follow-up time was 14 months (range, 12-16 months).
Conclusions: In selected patients, dorsum can be preserved without soft tissue envelope dissection. By combining multiple endonasal maneuvers is possible to obtain a dramatic change without dissecting the soft tissue envelope and at the same time avoiding any dorsal tissue resection: mosaic osteotomies for DKA conversion from S to V shaped dorsum, LDO and low septal strip resection for impaction and quadrangular cartilage flap rotation for profile setting. It is a versatile technique in selected patients, which leads to fast recovery and natural results

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
An Italian Online Survey Regarding the Use of Hyaluronidase in Previously Hyaluronic Acid-Injected Noses Looking for Surgical Rhinoplasty
Full text linkBACKGROUND: Nonsurgical nasal reshaping (nSNR) with hyaluronic acid (HA) filler is a well-established procedure performed to ameliorate nasal appearance and is considered a valid alternative to surgical rhinoplasty in selected patients. OBJECTIVES: The aim of our study is to evaluate the decision-making process and management of patients undergoing rhinoplasty, with previous HA filler injection, and evaluate if consensus could be achieved to recommend guidelines. METHODS: Between April and May 2021, an online survey was sent to 402 Italian surgeons of different specialties. The survey collected information regarding the types of treatment of patients who have previously undergone nSNR, who should undergo surgical rhinoplasty. For those surgeons using hyaluronidase, an additional information was collected. RESULTS: In a range of time of 2 months (April and May 2021), a total of 72 surgeons replied and completed the survey: out of the 402 questionnaires sent, the response rate was approximately 18%. The majority of respondents (61.5%) replied to inject hyaluronidase (HYAL) in patients who had to undergo a rhinoplasty but reported previous nSNR. Of the surgeons who use HYAL, 70% performed rhinoplasty after a waiting time of 3 to 4 weeks. CONCLUSIONS: Either direct surgical approach or hyaluronidase injection first seems to be a viable options. The use of HYAL before surgery is the choice with the broadest consensus in our survey. However, a larger case-control study with long follow-ups is necessary to understand if in patient seeking surgical rhinoplasty who already received nSNR, the injection of hyaluronidase before surgery is mandatory, recommended, or not
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
