AbstractAdenoid hypertrophy (AH) is a common disorder in children, resulting in chronic nasal congestion. This chronic congestion should be evaluated carefully because it can lead to chronic upper airway obstruction. Many authors have suggested that increased nasal resistance to respiration may cause disturbances in the pulmonary ventilation and carry the risk of cardiopulmonary diseases. Mean platelet volume (MPV) is a marker of platelet function and is positively associated with indicators of platelet activity. Mean platelet volume is an indicator of larger and more reactive platelets and has been shown to be increased in patients with vascular disease, including peripheral, pulmonary, and coronary artery disease. Recently, MPV levels have also been shown to be increased in patients with severe obstructive sleep apnea, and marked nasal septal deviation. Moreover, increased MPV has also been shown to have a prognostic role in cardiovascular disease. We investigated whether MPV is higher in patients with AH and whether higher MPV levels can be reduced by adenoidectomy. To the best of our knowledge, this is the first study to investigate MPV in patients with AH. Our results suggest that MPV, a determinant of platelet activation, is elevated in patients with AH and adenoidectomy is an effective therapeutic measure in such patients. Increased platelet activation may be related to an increase of cardiopulmonary risk in patients with AH.

A Rare Complication of Radiofrequency Tonsil Ablation: Horner Syndrome

Chronic tonsillitis is a common disease, and several different surgical techniques are used to treat this condition. In recent years, techniques such as radiofrequency ablation and coblation have been commonly used for tonsil surgery. In this report, we present the cases of two pediatric patients who developed ptosis, miosis, and enophthalmos (Horner syndrome) after radiofrequency ablation for tonsil reduction and discuss the technique of radiofrequency ablation of the tonsils. In the early postoperative period, miosis and ptosis were observed on the right side in one patient and on the left side in the other patient. Both patients were treated with 1 mg/kg/day methylprednisolone, which were tapered by halving the dose every 3 days. Miosis and ptosis improved after treatment in both patients. Along with the case presentation, we discuss the effectiveness and complications of radiofrequency ablation of the tonsils. These unusual complications of tonsil ablation may help ENT physicians who do not yet have a preferred surgical technique for tonsillectomy to make an informed decision. Limited data are available about the possible complications of radiofrequency ablation of the tonsils. The present report contributes to the literature on this topic.

Konka bulloza,havalanmis (pnomatize) veya icinde bir havali hucre bulunan orta konka icin kullanilan bir terimdir. Genellikle asemptomatik olmakla birlikte pnomatizasyonun buyuklugune ve nazal septumla olan iliskisine gore burun tikanikligi semptomlari verebilir ve ostiomeatal komplekse basi olusturmakta ise tikanmasina neden olarak sinuzite yol acabilir. Piyosele donusmesi nadirdir. Dev konka bulloza endoskopIk muayenede orta konkanin genislemis bir bolumu olarak gorulur. Konka bulloza kesin tanisi paranazal sinus bilgisayarli tomografisi (BT) ile koyulur. Tedavisinde endoskopik olarak orta konkanin lateral parsiyel rezeksiyonu yeterli ve minimal invazif bir yontemdir. Bu yazida sag nazal pasaji tamamen tikayan ve nazal vestibule kadar uzanim gosteren ve ayni tarafta sinuzite yol acan tek tarafli dev konka bulloza piyoseli olgusu sunulmustur
