LND was the only independent prognostic predictor of OS and DFS in patients with pN+ laryngeal SCC. Moreover, patients with LND ≥0.09 were significantly associated with high risk of regional recurrence. Thus, patients with LND ≥0.09 are at high risk of regional recurrence and death and may be considered for adjuvant chemoradiation.

Tympanosclerosis is a sequel of chronic otitis media characterized by the deposition of calcareous plaques following hyaline degeneration in the fibrous layer of the tympanic membrane and inside middle ear mucosa. It usually results from prior middle ear infections. In this study, results of treatment and clinical findings of the patients with tympanosclerosis are presented. Our objective is to determine the changes in middle ear caused by tympanosclerosis and intervene in the more problematic zone and find out the more useful treatment protocol for patients. Preoperative features, middle ear findings detected during surgery and postoperative hearing levels of the patients who were operated in our clinic between January 1996 and June 2006 due to tympanosclerosis were evaluated. Surgical treatment was performed on a total of 37 patients including 25 females and 12 males between ages of 11 and 71. Preoperative tympanic membranes perforations were presented at a rate of 91% and average airway bone gap was 37.8 dB. Bilateral involvement was present in 59%. Conductive-type hearing loss was present at a rate of 81%, whereas mixed-type hearing existed at a rate of 19%. Sclerotic plaques were most commonly localized in the attic with a rate of 72%. Post-op outcome was found to be 27% in the patients with air bone gap between 0-20 dB. The best hearing result belonged to type 1 patients. Cases in which stapes footplate was fixated had the worst result in terms of hearing. Teflon piston was only applied in one patient. Our tympanoplasty success was found to be 67%. The most common treatment method of tympanosclerosis is surgery. Stapedectomy is recommended in surgery instead of mobilization techniques. However, there is often recurrence and there is no curative treatment. Therefore rehabilitation with hearing device can be preferred as an adjunct. In the recent experimental studies, good results with topical or systemic agents have also been promising.

The aim of this study was to determine the most important risk factors in the development of otitis media with effusion (OME) in children with adenoid hypertrophy. A total of 539 patients undergoing surgery for adenoid hypertrophy (AH Group) (n = 429) or adenoid hypertrophy and otitis media with effusion (AH + OME Group) (n = 110) between February 2012 and February 2018 constituted the study group. Data were obtained on neonatal history (breastfeeding, bottle feeding), past health and medical history (presence of atopy or allergic rhinitis, snoring at night, cough, tonsillitis in the past 12 months), environmental factors (presence of pets, attending to daycare centers, district of school), family history (passive smoking at home, number of siblings, family size, parental education), and family income. The groups did not differ from each other for age (p = 0.684) and gender (p = 0.728). Our data support the presence of atopy or allergic rhinitis (p < 0.001), frequent (> 5) tonsillitis (p < 0.001), attending to daycare centers (p < 0.001), exposure to smoke (p < 0.001), having 3 or more siblings (p < 0.001), and 4 or more people in the household (p < 0.001) as the main risk factors for OME. Comprehensive knowledge of modifiable risk factors found in this study could help to minimise the complications of OME in children.
