Chronic otitis media usually presents with a benign tumor-like lesion of the temporal bone known as a cholesteatoma. The role of oxidative stress in the pathogenesis of chronic otitis media and cholesteatoma has not yet been fully explored. Therefore, the aim of this study was to investigate the oxidative stress markers and antioxidant enzymes in patients with cholesteatomatous and noncholesteatomatous chronic otitis media and in healthy subjects. A prospective controlled trial was performed on cholesteatomatous and noncholesteatomatous chronic otitis media patients in a tertiary referral center in a university hospital. A total of 75 subjects, including 25 cholesteatomatous and 25 noncholesteatomatous chronic otitis media patients and 25 healthy subjects participated in this study. Serum total oxidant status (TOS) and oxidative stress index (OSI) levels were significantly increased in the patient groups with or without cholesteatoma compared with the control group. Serum total antioxidant status (TAS) levels and Paraoxonase and arylesterase activity were significantly lower in the patient groups with or without cholesteatoma compared with the control group. Serum TOS and OSI levels were lower in the noncholesteatomatous group, whereas serum TAS levels were higher compared with the cholesteatomatous group. Serum arylesterase activity was significantly lower in the noncholesteatomatous group compared with the control group. The results of this study reveal that in cholesteatoma cases, the oxidative stress and antioxidant enzyme imbalance were more significant than in cases of chronic otitis media without cholesteatoma.
Incus interposition and bone cement ossiculoplasty are safe and reliable methods with which to manage incus long process defects. Bone cement ossiculoplasty gives a greater hearing gain in appropriate cases.
Osteoma is the most common benign tumor of the paranasal sinuses. They remain asymptomatic until the tumor reaches a certain size. Although the etiology of the osteomas is controversial, embryologic, traumatic, and infective theories have been proposed. Osteomas may be discovered at any age but are usually found during the fourth and fifth decades, and there is a male preponderance. In this retrospective study, we analyzed 25 patients with paranasal sinus osteomas who were treated surgically between 2005 and 2011. Age and sex of the patient, size and location of the tumor, clinical presentation, type of surgical approach, duration of follow-up, outcome, and any intraoperative or postoperative complications were obtained from the medical records of the patients. Diagnosis of osteoma was based on computed tomography findings and confirmed histopathologically in all cases. There were 9 men (36%) and 16 women (64%) with a mean age of 38.7 years. Tumor localization was divided as follows: ethmoid sinus in 14 patients (56%), frontal sinus in 9 patients (36%), and maxillary sinus in 2 patients (8%). Mean tumor size was 2.04 cm, ranging from 0.5 to 6.5 cm. External approach was used in 9 cases and endonasal endoscopic surgery was performed in 19 cases. Combination of endoscopic surgery and external surgery was performed in 3 cases. After at least 6 months of follow-up, all patients were symptom-free except 2 patients who underwent revision surgery. These 2 patients were also asymptomatic following revision surgery. Although there is an increasing trend to endoscopic surgery, external approach is recommended in large frontal osteomas and ethmoid osteomas with lateral extension and in case of intracranial or intraorbital involvement.
The aim of this study was to identify clinical factors that can predict malignancy in patients with persistent cervical lymphadenopathy. This retrospective study included 575 patients with persistent cervical lymphadenopathy who underwent surgical excision. The patients were divided into two groups according to their ages: group 1 (≤18 years) and group 2 (>18 years). Multiple logistic regression models and univariate analysis were performed to determine the association between clinical factors and malignancy. Male gender [odds ratio (OR) 4.184, 95 % confidence interval (CI) 1.823-9.602, p = 0.001], increased age (OR 1.072, 95 % CI 1.001-1.148, p = 0.046), left-sided lesions (OR 3.423, 95 % CI 1.407-8.329, p = 0.007), and larger lymph node size (OR 1.445, 95 % CI 1.021-2.044, p = 0.038) were significantly associated with malignancy in group 1. Male gender (OR 3.761, 95 % CI 2.361-5.992, p = 0.001), increased age (OR 1.015, 95 % CI 1.003-1.027, p = 0.018), duration of the disease (OR 0.770, 95 % CI 0.668-0.888, p = 0.001), and the presence of B symptoms (OR 4.996, 95 % CI 2.862-8.721, p = 0.001) were significantly associated with malignancy in group 2. The sensitivity and specificity of the models were 84 and 61.5 % for group 1 and 77.9 and 67.9 % for group 2, respectively. Increasing age and male gender were found to be associated with malignancy in all age groups. Larger lymph node size and left-sided lymphadenopathy were significant predictors of malignancy in children. Presence of B symptoms was found to be associated with malignancy in adults. Our results indicated that increasing duration of lymphadenopathy and the presence of bilaterality render the lymph node more likely to be benign in adults. No significant association was found between the involved neck site and malignancy for all age groups.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
