Introduction: The complexity of the nasal tip structures and the impact of surgical maneuvers make the prediction of the final outcome very difficult. Therefore, no single technique is enough to correct the several anatomical presentations, and adequate preoperative planning represents the basis of rhinoplasty.
Objective: To present results of rhinoplasty, through the gradual surgical approach to nasal tip definition based on anatomical features, and to evaluate the degree of patient satisfaction after the surgical procedure.
Article Synopsis
- Juvenile nasopharyngeal angiofibroma (JNA) is a rare vascular tumor that mostly affects young males, particularly between the ages of 14 and 25, and is linked to the GSTM1 gene.* -
- A study in Brazil examined ten male patients with JNA, finding that 40% had the GSTM1-null genotype, but there was no significant correlation between their stage of disease or age and the genotype.* -
- The results suggest a potential association between the GSTM1-null genotype and JNA in this specific Brazilian population, highlighting the need for further research in this area.*
Article Synopsis
- Serotonin affects various bodily functions, including sleep, and variations in the 5-HT2A receptor gene may increase the risk for obstructive sleep apnea syndrome (OSAS).
- This study aimed to assess the presence of specific genetic variations (102T-C and -1438G-A polymorphisms) in Brazilian patients with and without OSAS.
- Findings showed no significant difference for the 102T-C variant, but the AA genotype of the -1438G-A polymorphism was more common in OSAS patients, suggesting a potential link between this genetic variation and the condition.
Article Synopsis
- Obstructive sleep apnea syndrome (OSAS) is influenced by genetic factors, particularly the serotonin (5-HT) system, which regulates various bodily functions including sleep.
- The study aimed to analyze the prevalence of specific genetic polymorphisms (T102C and -1438G/A) in the 5-HTR2A gene among patients with and without OSAS using DNA from blood samples.
- Results indicated a higher prevalence of males with OSAS, no difference in T102C polymorphism, but a significant association between the -1438G/A polymorphism and OSAS, suggesting a potential genetic link.
Males with obstructive sleep apnea syndrome (OSAS) may present decreased testosterone serum levels because of hypoxemia. To correlate testosterone levels in OSAS patients with laboratory parameters. 103 registries of OSAS patients were reviewed from 2002 to 2009.
View Article and Find Full Text PDFUnlabelled: Orthognathic surgeries are very important for both the correction of dentofacial deformities as well as for the treatment of obstructive sleep apnea/hypopnea syndrome. Nowadays, most of the population presents some type of morphological and/or functional disorder of the stomatognathic system.
Aim: The present study aims at assessing the information from the individuals treated in the Orthognathic Surgical Service of a Medical School.
Unlabelled: Facial traumas are frequent in emergencies, and they require the diagnosis of fractures and associated lesions.
Aim: To analyze epidemiological data concerning facial trauma care.
Materials And Methods: Three hundred and fifty-five charts from patients with facial trauma treated by the Service of Otorhinolaryngology, from January 2002 to December 2008, were revised.
Obstructive sleep apnea hypopnea syndrome (SAHS) is a complex disease of the upper respiratory airways. SAHS physiopathology is multifactorial in which airway compliance is a very important component. To evaluate the tissue changes in the palatopharyngeal muscle by morphometric, histochemical, immunohistochemical, and stereological quantification, with special attention to extracellular matrix associated with this muscle at the structural and ultrastructural levels.
View Article and Find Full Text PDFUnlabelled: Juvenile nasopharyngeal angiofibroma (JNA) is a rare tumor in adolescent males. It originates in the nasopharynx.
Aim: To present the experience of JNA management at an Otorhinolaryngology Service between 2001 and 2008.
Squamous cell carcinoma of the tongue is one of the most common head and neck cancer. Treatment in the early stages is still controversial. This study aims to correlate the apoptosis rate of primary tongue cancer with cervical node metastasis, found in the histopathological studies of specimens obtained from neck dissections or during clinical follow-up.
