Exposure to ototoxic agents and hearing loss: A review of current knowledge
2014
Several experimental and clinical studies have shown that a variety of ototoxic agents (such as drugs, industrial chemicals and noise) can cause sensorineural hearing loss. The most common ototoxic drugs used in clinical practice include: aminoglycoside and macrolide antibiotics, quinoline anti-malarials, platinum analog antineoplastics, loop diuretics, and acetylsalicylic acid. Among chemical agents with potential ototoxic properties are: organic solvents, heavy metals, organotins, nitriles, asphyxiants, and pesticides/herbicides. Acoustic exposure to high intensity and/or prolonged noise can also cause permanent threshold shifts in auditory perception. Ototoxic agents can influence audito…
Buccal fat pad excision for cheek refinement: A systematic review
2021
Background Buccal Fat Pad (BFP) excision has become an aesthetic surgical procedure. Although this procedure is quite common, it is important to bear in mind that the scientific evidence supporting the efficacy of this treatment is scarce and of low quality. The purpose of this systematic review was to analyse all relevant data to assess the efficacy and safety of BFP excision for improving midface aesthetics. Material and Methods A thorough search of MEDLINE (PubMed), Scopus and Cochrane Library databases was conducted. The PICO approach was used where healthy patients seeking cheek slimming and facial silhouette refining undergo BFP excision and were compared before and after surgery in t…
Salivary gland cancer in Southern Brazil: a prognostic study of 107 cases.
2020
Background Salivary gland cancers (SGC) represent an uncommon group of heterogeneous tumors. We performed a retrospective survey of SGC diagnosed in a reference center for treatment of malignant tumors from the south of Brazil aiming to determine the prognostic value of demographic, clinic and pathologic features. Material and Methods Cases diagnosed as SGC between 2006 and 2016 were retrospectively collected. Medical records were examined to extract demographic, clinic, pathologic and follow-up information. Results One-hundred and seven cases of SGC were identified. The most common SGC were mucoepidermoid carcinoma (MEC) (n = 39) followed by adenoid cystic carcinoma (AdCC) (n = 29). Among …
Optimization of the Speech Test Material in a Group of Hearing Impaired Subjects: A Feasibility Study for Multilingual Digit Triplet Test Development
2021
Background: The development of the global digit-in-noise test requires optimization of each language version on a group of normal-hearing native-speakers. An alternative solution may be an adaptive optimization during ongoing tests in a group of subjects with unknown hearing impairments. The objective of the research was to compare the optimization results between these groups. Methods: Digit triplets consisting of three pseudo-randomly selected digits were presented in speech-shaped noise at various signal-to-noise ratios (SNRs), according to the protocol of the final speech test. Digit-specific and position-specific speech reception thresholds (SRTs) were determined and compared between g…
Does anti-inflammatory drugs modify the severe odontogenic infection prognosis? A 10-year’s experience
2020
Background Numerous biochemical datas support the noxious role of anti-inflammatory drugs on immune response. Those observations are often put forward for unfavorable evolution of odontogenic infection but has never been really proven in clinic. The aim of this study is to try to clarify this role based on the collection of the clinical course of odontogenic infections over a 10-year analysis period. Material and Methods The investigators implemented a prospective observational study. The sample was composed of patients managed between January 2004 and December 2014 for severe odontogenic infection based on three criteria: hospital admission, intravenous antibiotic therapy, tooth extraction…
Temporomandibular joint arthrocentesis guided by ultrasonography: An anatomical study
2021
The temporomandibular joint (TMJ) arthrocentesis is a common procedure in maxillofacial surgery departments for the treatment of TMJ dysfunction. The use of ultrasonography in this area is rare, and in the vast majority of cases only as a diagnostic, and non-therapeutic use. Through this study we propose the equipment and ultrasound parameters necessary to obtain detailed and practical images when using ultrasonography as a therapeutic guide in arthrocentesis of TMJ. In addition, we provide data regarding the placement and working angulations of both the ultrasound probe and the needle that are ideal for facilitating image-guided puncture. It is a simple technique, with a relatively short l…
Alveolar distraction osteogenesis for dental implant treatments of the vertical bone atrophy : a systematic review
2019
Background To determine if alveolar vertical distraction osteogenesis obtains better results compared to other bone regeneration treatments (guided bone regeneration with membranes and / or filling material, or autogenous bone graft) in terms of bone gain, complications, and implant survival and success rates. Material and Methods An electronic search was performed in Pubmed (MEDLINE), Cochrane Library and Scopus databases in March 2017. Besides, a manual search was carried out. Inclusion criteria were randomized controlled trials published within the last 10 years with at least 1 year of follow-up after implant placement. No language restriction was applied. Exclusion criteria were studies…
Erythritol-enriched powder and oral biofilm regrowth on dental implants: an in vitro study.
2021
Background Peri-implant mucositis and peri-implantitis are the main biological complications associated with dental implants. Since most authors agree that bacteria play a major etiological role, the main aims of this study were to determine if a formulation of erythritol and chlorhexidine applied with an air polishing system inhibits biofilm regrowth over dental implants and to compare the decontamination capacity of this therapy with that of mechanical removal by saline and gauze. Material and Methods A multispecies biofilm (P. gingivalis, A. actinomycetemcomitans, F. nucleatum, A. naeslundii, V. parvula and S. oralis) was grown for 14 days on 52 dental implants in an artificial mouth. Th…
Influence of the prosthetic arm length (palatal position) of zygomatic implants upon patient satisfaction
2016
Background: To assess the influence of the prosthetic arm length (palatal position) of zygomatic implants upon patient comfort and stability, speech, functionality and overall satisfaction. Material and Methods: A retrospective clinical study was made of patients subjected to rehabilitation of atrophic maxilla with complete maxillary implant-supported fixed prostheses involving a minimum of two zygomatic implants (one on each side) in conjunction with premaxillary implants, and with 12 months of follow-up after implant loading. Subjects used a VAS to score general satisfaction, comfort and stability, speech and functionality, and the results were analyzed in relation to the prosthetic arm l…
The outcome of intraoral onlay block bone grafts on alveolar ridge augmentations: A systematic review
2015
Aim: The purpose of this study was to systematically review clinical studies examining the survival and success rates of implants placed with intraoral onlay autogenous bone grafts to answer the following question: do ridge augmentations procedures with intraoral onlay block bone grafts in conjunction with or prior to implant placement influence implant outcome when compared with a control group (guided bone regeneration, alveolar distraction, native bone or short dental implants.)? Material and Method: An electronic data banks and hand searching were used to find relevant articles on vertical and lateral augmentation procedures performed with intraoral onlay block bone grafts for dental im…
