Anterior Skull Base Surgery via Endoscopic Endonasal Approach: Outcomes and Analysis.

BACKGROUND: This study was retrospectively conducted to evaluate the postoperative surgical results of our patients with anterior skull base mass, defect, and/or cerebrospinal fluid rhinorrhea who underwent reconstruction via endoscopic endonasal approach and to share our experiences. METHODS: Sociodemographic features of patients who had undergone endoscopic surgery in our clinic due to anterior skull base mass, defect, or rhinorrhea were evaluated in terms of etiological factors, surgical method, pathology, postoperative complications, need for revision surgery and comorbid disease. RESULTS: A total of 131 patients were included; 76 were male and mean age was 36.2 years. Endoscopic endonasal surgery was performed for nasal mass (70.2%) in 92 cases, rhinorrhea (17.6%) in 23 cases, chronic sinusitis (7.6%) in 10 cases, and gunshot injury (4.6%) in 6 cases. After surgery, benign mass pathology was detected in 75 patients and malignant mass pathology was detected in 23 patients. Osteoma was the most common among benign formations, and squamous cell carcinoma was the most common among malignant formations. The most common cause of surgical revision was nasal masses (25 cases, 77.4%). CONCLUSION: Endoscopic intracranial interventions and increased anterior skull base surgery are garnering increased interest of physicians as endoscopic approaches are gaining popularity in recent years. Successful results are achieved through appropriate diagnostic methods and endoscopic approaches. Success rates will be further increased due to developing technology and imaging methods, while the risk of complications and revision surgery will be further reduced.

Masking Treatment and its Effect on Tinnitus Parameters.

OBJECTIVE: Tinnitus is described as the perception of sound without any external acoustic stimulation. Any pathology of auditory pathways or any system of the human body may result with tinnitus. The pathophysiology of tinnitus accompanying the disorders of auditory system is not fully understood and there is not any particular effective treatment method has been specified. Tinnitus masking therapy has been reported as an effective treatment modality in the treatment of tinnitus. In this study, the results of tinnitus masking treatment on the parameters were evaluated prospectively. PATIENTS AND METHODS: Patients with normal physical examination was enrolled in the study. Blood tests (complete blood count, biochemical analysis of lipid profile, and thyroid hormones), pure tone audiometry, tympanometric measurement of the middle ear pressure and stapedial reflexes were performed, Sixty six patients with normal results of blood tests and normal hearing thresholds with type A tympanogram were included. Tinnitus sufferers questionnaires (socio-demographics, clinical information, Tinnitus Handicap Inventory (THI), Beck Depression Inventory (BDI) was filled, audiological tests were performed, tinnitus parameters (frequency, intensity, minimal masking levels, residual inhibition) were measured. After four weeks of the treatment the questionnaires were repeated. RESULTS: Masking treatment for tinnitus patients resulted with significant decrease in Tinnitus Handicap Inventory and VAS scores. After four weeks of the masking treatment the questionnaire was repeated. Twenty patients did not respond to treatment. CONCLUSION: Masking therapy is one of the most effective methods of treatment for tinnitus patients. Masking therapy, that is not invasive and cost-effective has an important place in the treatment of tinnitus. Especially in a short time provides a significant reduction in tinnitus parameters.
