    Background
    Chronic adenotonsillar hypertrophy which causes airway obstruction and obstructive sleep apnea is the most common indication for adenotonsillectomy in children. Obstructive sleep apnea is almost always associated with adenotonsillar hypertrophy in this age group. Mean platelet volume (MPV) is an indicator of the platelet size. Platelet size reflects the platelet function and activation. Larger platelets have denser granules and higher thrombosis potential. So higher MPV levels are correlated with higher platelet activity and inflammation intensity. Increased platelet activity has a great role in atherosclerosis, ischemic heart disease and cardiovascular morbidity and mortality.
    Purpose
    The aim of this study is to evaluate the MPV level in patients who underwent adenotonsillectomy.
    Methods
    In this longitudinal study, 37 patients with chronic adentonsillar hypertrophy who underwent adenotonsillectomy were enrolled. MPV levels before and 3 weeks after surgery were recorded and compared with paired comparison analysis. The significance level was less than 0.05.
    Results
    MPV levels were 8.7 ±0.9 and 8.2±1.2 fL, before and after adenotonsillectomy, respectively. A statistically significant decrease was noted in MPV levels following surgery (P=0.022).
    Conclusion
    MPV levels of the patients with adenotonsillar hypertrophy significantly decreased postoperatively. These results demonstrate that MPV level changes can be reversed and treated by adenotonsillectomy.

    Background
    One of the essential components during stapedectomy is a good cooperation between patient and surgeon. Remifentanil is commonly used short – acting opioid to assess the results during the procedure.
    Purpose
    The aim of this study is to investigate the effects of propofol- remifentanil and midazolam -remifentanil on hemodynamic parameters intra- Stapedectomy.
    Methods
    In this randomized, double-blinded trial, 36 patients with otosclerosis were evaluated in two equal groups, which received propofol- remifentanil and midazolam- remifentanil each. We recorded cardio-respiratory parameters, side effects and intra-operative cooperation of the patients.
    Results
    There was a statistically significant difference in blood pressure reduction between two groups. The severity of the bleeding and desirable cooperation of patients in midazolam- based regimen was better than propofol- based regimen (p- value= 0.01 and 0.02 respectively). The average operative time in patients who received propofol was about 15 minutes more than the other group (p- value=0.01).
    Conclusion
    The midazolam - remifentanil is more appropriate sedative, because it provides hemodynamic stability and a better cooperation of patient intra - stapedectomy.

    Mucocele is defined as the accumulation of mucus within a cystic structure lined by mucoperiosteum causing bone remodeling and erosion. The sphenoidal sinus mucoceles, due to its proximity to the optic nerve, can cause ocular complications. A50-year-old woman with a history of previous endoscopic nasal surgery (30 months ago), blurred vision, severe right-sided orbital pain since three weeks ago and severe unilateral headache was admitted. Mucocele related orbital apex syndrome due to the sphenoid sinus mucocele was diagnosed. The optic nerve was fully dehiscent and under compression. Paranasal sinus pathologies must be taken into consideration when a patient with the diagnosis of optic neuropathy and involvement of the superior orbital fissure is approached.

    Hearing loss is caused by several factors, such as genetic, aging, drug, infection and exposure to loud sound and around 360 million people worldwide have disabling hearing loss. Here, we discuss the current and future strategies for the treatment of hearing loss.
