- Orthodontic measurements and nasal respiratory function after surgically assisted rapid maxillary expansion: an acoustic rhinometry and rhinomanometry study(2012) ZAMBON, C. E.; CECCHETI, M. M.; UTUMI, E. R.; PINNA, F. R.; MACHADO, G. G.; PERES, M. P. S. M.; VOEGELS, R. L.The present study sought to assess nasal respiratory function in adult patients with maxillary constriction who underwent surgically assisted rapid maxillary expansion (SARME) and to determine correlations between orthodontic measurements and changes in nasal area, volume, resistance, and airflow. Twenty-seven patients were assessed by acoustic rhinometry, rhinomanometry, orthodontic measurements, and use of a visual analogue scale at three time points: before surgery; after activation of a preoperatively applied palatal expander; and 4 months post-SARME. Results showed a statistically significant increase (p < 0.001) in all orthodontic measurements. The overall area of the nasal cavity increased after surgery (p < 0.036). The mean volume increased between assessments, but not significantly. Expiratory and inspiratory flow increased over time (p < 0.001). Airway resistance decreased between assessments (p < 0.004). Subjective analysis of the feeling of breathing exclusively through the nose increased significantly from one point in time to the next (p < 0.05). There was a statistical correlation between increased arch perimeter and decreased airway resistance. Respiratory flow was the only variable to behave differently between sides. The authors conclude that the SARME procedure produces major changes in the oral and nasal cavity; when combined, these changes improve patients' quality of breathing.
bookPart Malformações nasais (cisto dermoide, meningoencefalocele e atresia de coanas)(2018) BAPTISTA, Marco Antônio Ferraz de Barros; PINNA, Fabio de Rezende- Juvenile angiofibroma: major and minor complications of preoperative embolization(2012) OGAWA, Alex Itar; FORNAZIERI, Marco Aurelio; SILVA, Leonardo Victor Espana Rueda da; PINNA, Fabio de Rezende; VOEGELS, Richard Louis; SENNES, Luis Ubirajara; PUGLIA JUNIOR, Paulo; CALDAS, Jose Guilherme Mendes PereiraIntroduction: Juvenile angiofibromas (JA) are highly vascular, benign tumours for which surgery is the treatment of choice. In most services, embolisation is performed prior to resection. Nevertheless, there are few data on the complications of preoperative embolisation for JA. Aim: To describe major and minor complications of preoperative embolisation in a 32-year experience of patients undergoing surgical resection of JA at a tertiary hospital. Methods: Retrospective chart review study of 170 patients who underwent surgical resection of JA at a tertiary hospital between September 1976 and July 2008. Results: All patients were male. Age ranged from 9 to 26 years. Ninety-one patients had no complications after embolisation. Overall, 105 complication events occurred of which four major and 101 minor. Conclusion: In our series, preoperative embolisation for JA produced no irreversible complications and no aesthetic or functional sequelae. The vast majority of complications were transient and amenable to clinical management.
- Nasal Polyposis: More than a Chronic Inflammatory Disorder-A Disease of Mechanical Dysfunction -The Sao Paulo Position(2019) PEZATO, Rogerio; VOEGELS, Richard Louis; PIGNATARI, Shirley; GREGORIO, Luiz Carlos; BEZERRA, Thiago Freire Pinto; GREGORIO, Luciano; BALSALOBRE, Leonardo; TEPEDINO, Miguel Soares; CORONEL, Nathalia; PINNA, Fabio de Rezende; NETO, Jose Mendes; OLIVEIRA, Pedro; MACOTO, Eduardo; STEFANINI, Renato; FIGUEIREDO, Claudia; HADDAD, Fernanda; PILAN, Renata; SOTER, Ana Bezerra; MELO, Nelson Almeida; CANDIDO, Danilo Almeida; AMARAL, Jonatas do; SANTOS, Rodrigo de Paula; ZELE, Thibaut Van; FUJITA, Reginaldo; DREYFUSS, Juliana L.; CHAMON, Wallace; ALENCAR, Adriano Mesquita; PEREZ-NOVO, Claudina; STAMM, Aldo CassolIntroduction The importance of our study lies in the fact that we have demonstrated the occurrence of mechanical dysfunction within polypoid tissues, which promotes the development of polyps in the nasal cavity. Objective To change the paradigm of nasal polyposis (NP). In this new conception, the chronic nasal inflammatory process that occurs in response to allergies, to pollution, to changes in the epithelial barrier, or to other factors is merely the trigger of the development of the disease in individuals with a genetic predisposition to an abnormal tissue remodeling process, which leads to a derangement of the mechanical properties of the nasal mucosa and, consequently, allows it to grow unchecked. Data Synthesis We propose a fundamentally new approach to intervening in the pathological process of NP, addressing biomechanical properties, fluid dynamics, and the concept of surface tension. Conclusion The incorporation of biomechanical knowledge into our understanding of NP provides a new perspective to help elucidate the physiology and the pathology of nasal polyps, and new avenues for the treatment and cure of NP.
- Is Olfactory Epithelium Biopsy Useful for Confirming Alzheimer's Disease?(2019) GODOY, Maria Dantas Costa Lima; FORNAZIERI, Marco Aurelio; DOTY, Richard L.; PINNA, Fabio de Rezende; FARFEL, Jose Marcelo; SANTOS, Glaucia Bento dos; MOLINA, Mariana; FERRETTI-REBUSTINI, Renata E. L.; LEITE, Renata E. P.; SUEMOTO, Claudia K.; GRINBERG, Lea T.; PASCRALUCCI, Carlos A. G.; VOEGELS, Richard Louis; NITRINI, Ricardo; JACOB FILHO, WilsonObjectives: The clinical symptoms of Alzheimer's disease (AD) are preceded by a long asymptomatic period associated with ""silent"" deposition of aberrant paired helical filament (PHF)-tau and amyloid-beta proteins in brain tissue. Similar depositions have been reported within the olfactory epithelium (OE), a tissue that can be biopsied in vivo. The degree to which such biopsies are useful in identifying AD is controversial. This postmortem study had 3 main goals: first, to quantify the relative densities of AD-related proteins in 3 regions of the olfactory neuroepithelium, namely, the nasal septum, middle turbinate, and superior turbinate; second, to establish whether such densities are correlated among these epithelial regions as well as with semi-quantitative ratings of general brain cortex pathology; and third, to evaluate correlations between the protein densities and measures of antemortem cognitive function. Methods: Postmortem blocks of olfactory mucosa were obtained from 12 AD cadavers and 24 controls and subjected to amyloid-beta and PHF-tau immunohistochemistry. Results: We observed marked heterogeneity in the presence of the biomarkers of tau and amyloid-beta among the targeted olfactory epithelial regions. No significant difference was observed between the cadavers with AD and the controls regarding the concentration of these proteins in any of these epithelial regions. Only one correlation significant was evident, namely, that between the tau protein densities of the middle and the upper turbinate (r = .58, P = .002). Conclusion: AD-related biomarker heterogeneity, which has not been previously demonstrated, makes comparisons across studies difficult and throws into question the usefulness of OE amyloid-beta and PHF-tau biopsies in detecting AD.
- Safety and efficacy of superior turbinate biopsies as a source of olfactory epithelium appropriate for morphological analysis(2020) GARCIA, Ellen Cristine Duarte; ROSSANEIS, Ana Carolina; PIPINO, Alexandre Salvatore; GOMES, Gustavo Vasconcelos; PINNA, Fabio De Rezende; VOEGELS, Richard Louis; DOTY, Richard L.; VERRI, Waldiceu Aparecido; FORNAZIERI, Marco AurelioPurpose There is no standardized approach for preserving olfactory function in the side of the nose where biopsy of the olfactory epithelium (OE) is performed. Moreover, a gold standard technique for obtaining human OE in vivo is still lacking. We determined the efficacy of obtaining good-quality OE specimens suitable for pathological analysis from the lower half of the superior turbinate and verified the safety of this procedure in maintaining bilateral and unilateral olfactory function. Methods In 21 individuals without olfactory complaints and who had undergone septoplasty and inferior turbinectomy OE biopsy was made during septoplasty. Olfactory function, both unilateral and bilateral, was assessed using the University of Pennsylvania Smell Identification Test (UPSIT) before and 1 month after the procedure. Specimens were marked with the olfactory marker protein for confirmation of OE presence. Results Ninety percent of the samples contained OE, although clear histological characterization was possible from only 62%. There was no deterioration of UPSIT scores either bilaterally or unilaterally on the side of the biopsy. Patients also maintained the ability to identify individual odorants. Conclusion Biopsies of the lower half of the superior turbinate do not affect olfactory function and show strong efficacy in yielding OE tissue and moderate efficacy for yielding tissue appropriate for morphological analysis. Future studies are needed to assess the safety of this procedure in other OE regions.
- Assessment of quality of life after endoscopic sinus surgery for chronic rhinosinusitis(2012) BEZERRA, Thiago Freire Pinto; PICCIRILLO, Jay F.; FORNAZIERI, Marco Aurelio; PILAN, Renata Ribeiro de Mendonca; PINNA, Fabio de Rezende; PADUA, Francini Grecco de Melo; VOEGELS, Richard LouisChronic rhinosinusitis is a disease of undefined etiology that significantly impacts the quality of life of its patients. Various studies carried out in countries other than Brazil have shown endoscopic sinus surgery as an effective means of treating this condition. Objective: This study aims to analyze, with the aid of SNOT-20, the association between endoscopic sinus surgery and disease-specific quality of life of Brazilian patients treated for chronic rhinosinusitis accompanied or not by nasal polyps. Materials and Methods: This prospective study enrolled patients submitted to endoscopic sinus surgery after drug therapy failed to improve their symptoms. They were assessed based on questionnaire SNOT-20p before and 12 months after surgery. Improvement on total scores and on the five items deemed more important by each patient were assessed. The study also looked into the correlation between preoperative scores and postoperative improvement and if there were any gender-related improvement differences. Results: Forty-three patients aged 44 (19), md (IQR), 65% of whom (26/43) were males. Statistically significant improvement was seen on SNOT-20 and SNOT-20(5+) and a correlation was established between preoperative scores and postoperative improved scores (p<0.001). No gender-related differences were observed in quality of life. Conclusion: Endoscopic sinus surgery in patients with chronic rhinosinusitis is associated with statistically significant improvements in disease-specific quality of life.
- Transpterygoid Approach to a Dermoid Cyst in Pterygopalatine Fossa(2014) ORDONES, Alexandre Beraldo; FORNAZIERI, Marco Aurélio; PINNA, Fábio de Rezende; BEZERRA, Thiago Freire Pinto; VOEGELS, Richard Louis; SENNES, Luiz UbirajaraObjective To describe a case of dermoid cyst arising from the pterygopalatine fossa and review the literature. Methods We report a case of a 23-year-old man who suffered a car accident 2 years before otolaryngologic attendance. He had one episode of generalized tonic-clonic seizure and developed a reduction of visual acuity of the left side after the accident. Neurologic investigation was performed and magnetic resonance imaging revealed an incidental finding of a heterogeneous ovoid lesion in the pterygopalatine fossa, hyperintense on T2-weighted imaging. Results Endoscopic sinus surgery with transpterygoid approach was performed. The ovoid lesion was noted in the pterygopalatine fossa. Puncture for intraoperative evaluation showed a transparent thick fluid. Surprisingly, hair and sebaceous glands were found inside the cyst capsule. The cyst was excised completely. Histologic examination revealed a dermoid cyst. The patient currently has no evidence of recurrence at 1 year postoperatively. Conclusion This unique case is a rare report of a dermoid cyst incidentally diagnosed. An endoscopic transnasal transpterygoid approach may be performed to treat successfully this kind of lesion. Although rare, it should be considered in the differential diagnosis of expansive lesions in the pterygopalatine fossa, including schwannoma, angiofibroma, esthesioneuroblastoma, osteochondroma, cholesterol granuloma, hemangioma, lymphoma, and osteoma.
