Background/Objective. Cisplatin is a widely used chemotherapeutic agent, but its ototoxicity side effect can occur in the majority of patients. Lots of agents were tried to prevent this, but there is not a routine treatment modality yet. The aim of this study was to evaluate the otoprotective effect of sertraline, which is an antidepressant with neuroprotective effects, against cisplatin, in rats. Design. Experimental animal study. Material and Methods. Forty-eight rats were randomly separated in two groups as groups I and II. Group I was identified as the control group and only a single dose of intraperitoneal cisplatin was administered. In group II, in addition to cisplatin, sertraline was administered to the rats through an oral cannula for ten-day period. Distortion product otoacoustic emission measurements were performed at the first day and the 10th day. Results. When the ototoxicity rates after cisplatin in group I and group II in distortion product otoacoustic emission measurements were compared, it was statistically significantly lower in group II in frequencies of 5652, 6165, 6726, 7336, and 7996 Hz (P < 0.05). Conclusion. Sertraline seems to have a protective effect on cisplatin ototoxicity and could be used to prevent the ototoxicity and also to treat the depression that occurred in cancer patients together.

Objectives:Septoplasty is the most frequently performed surgical procedure in patients with nasal obstruction. However, nasal obstruction may persist or recur after septoplasty in some patients. In this study, the authors aimed to determine the causes of nasal obstruction after septoplasty. Methods:Fifty consecutive patients who admitted to our clinic with the complaints of persistent or recurrent nasal obstruction after primary septoplasty and had revision surgery between 2011 and 2015 were included in this study. Demographic data and physical examination findings of the patients were recorded. Results:There were 33 men (66%) and 17 women (34%) with a mean age of 37.3 ± 10.5 (range, 21–57) years. Deviation of perpendicular plate of ethmoid bone (44%), inferior turbinate hypertrophy (36%), concha bullosa (26%), caudal septal deviation-nostril asymmetry (20%), and alar collapse (6%) were the pathologies that were unaddressed during primary surgery. The iatrogenic causes of nasal obstruction after septoplasty were collumellar retraction–nasal tip ptosis (46%), nasal synechiae (20%), nasal septal perforation (10%), and saddle-nose/flat nose deformity (10%). Conclusions:Iatrogenic deformities due to surgery and pathologies ignored during primary surgery may cause persistent/recurrent nasal obstruction after primary septoplasty. A detailed physical examination and objective tests showing the site of nasal obstruction, an extensive surgical plan that covers all diagnosed pathologies, and a careful postoperative care must be undertaken to prevent undesired postoperative results.

BACKGROUND Retrospective data on 165 patients who presented with a parotid mass and underwent surgery in our clinics during 2000-2009 were examined. The obtained data (demographic data, surgical procedures, histopathological diagnoses) were compared to similar studies to make contributions to the literature. MATERIALS AND METHODS Patients were classified according to their histopathological diagnosis. Surgical procedures and patient follow-up were clarified. The results are presented as means and standard deviations. RESULTS Of the 165 masses, 134 (81.3%) were benign and 31 (18.7%) were malignant. Pleomorphic adenoma was the most common benign tumour (79 patients, 59%). Lymphoma and adenoid cystic carcinoma were equally common and were the most common malignant parotid gland tumours (both 6 patients, 19.3%). The most frequent surgical procedure was superficial parotidectomy (92 patients, 55.7%), and the most commonly encountered surgical complication was facial paralysis (12 patients, 7.2%). CONCLUSIONS Our data are generally in line with the literature but lymphoma was more common than in most previous reports. Although the number of cases was low, the high incidence of parotid gland lymphoma was remarkable.

OBJECTIVE The aim of this study was to compare the hearing results of embedding the partial ossicular reconstruction prosthesis (PORP) underneath the malleus with the malleus relocation technique and tympanic membrane graft in the presence of the malleus. MATERIALS AND METHODS A retrospective review of patient charts and audiometric results in a tertiary referral center was conducted. In total, 83 patients who underwent intact canal tympanoplasty with mastoidectomy between 2010 and 2015 were included and divided into two different groups: malleus assembly to the stapes head (MASH) and tympanic membrane assembly to the stapes head (TASH). Pre- and postoperative audiometric results were assessed. The air-bone gap (ABG) and hearing gains were evaluated according to the groups. RESULTS In MASH, 86.1% (n=31) of the patients were received successful surgery and the postoperative average ABG was 10.41 dB. In TASH, 82.9% (n=39) of the patients were considered successful and the postoperative ABG was 13.27 dB. According to the overall data, MASH was more statistically successful than TASH, and hearing gains at 500 Hz (p<0.036), 2000 Hz (p<0.031), and PTA (p<0.22) were statistically significant better in the MASH group. CONCLUSION Malleus relocation is a successful technique with the presence of the malleus and provides better hearing outcomes than direct placement under the tympanomeatal flap. Both malleus- and tympanomeatal flap-linked groups were successful, but the malleus-linked group showed better ABGs.

INTRODUCTION Obstructive Sleep Apnea syndrome (OSA) is the most serious consequence of adenoid hypertrophy (AH) and it is one of the most common reasons of nocturnal hypoxia in children. There is some information about the relationship between childhood OSA and atherosclerosis or cardiac diseases. In this study, we evaluated the relationship between, neutrophil-lymphocyte ratio (NLR) and AH which is the most frequent cause leading OSA in children. AIM Thus we aimed to contribute about subject of preoperative and postoperative NLR values in patients undergoing adenoidectomy that there is limited information. MATERIALS AND METHODS The study group comprised 76 children undergoing adenoidectomy. A preoperative and 3(rd)-month postoperative complete blood cell count was performed to calculate the NLR values in all patients. The NLR values were calculated as the ratio of neutrophils to lymphocytes in peripheral blood. Data analysis was performed using SPSS 15. RESULTS The mean NLR (min - max) was 1.0 (0.16-3.57) preoperatively and 1.06 (0.35-4.95) 3 months postoperatively (p = 0.052> 0.05). Haemoglobin 12.9 ± 0.95 (preop) 12.94 ± 0.91 (postop) (p= 0.522), WBC (min-max) 7.75 (3.90-14.99) 7.8 (4-15.64) (p= 0.297 <0.005), platelet 344.5 ± 98.7 328.4 ± 68.9 (p<0,005). CONCLUSION There is limited information in the English literature. This study has investigated the association between the NLR and adenoidectomy. The results of the present study demonstrate that the NLR is not a statistically significant inflammatory factor. So, NLR values do not appear related to stage of upper airway obstruction.

Objective:The authors aimed to evaluate the intraoperative features and the results of postoperative hearing gain successes of patients with tympanosclerosis who were treated surgically in our clinic. Material and Methods:A retrospective analysis was conducted on 151 ears with tympanosclerosis of 138 patients who operated because of chronic otitis media or only tympanosclerosis, between January 2007 and June 2014. They were evaluated by appealing complain, complain duration, accompanying systemic disorders, tympanic membrane condition, localization of sclerotic plaque, damage in ossicular chain, existence of cholesteatoma, operation procedure type, hearing reconstruction type, preoperative, and last postoperative audiometric findings in every frequency both bone and air way. Results:In the group of Wielinga-Kerr Group 3 (isolated stapes fixation), no statistically significant results were found in preoperative and last postoperative audiometric findings in every frequency both bone and air conduction (BC and AC) (P > 0.05). In the Wielinga-Kerr Group some results had significant (P < 0.05) and some results had highly significant (P < 0.001). Conclusions:Patients with less impact on ossicular chain and limited localization of sclerotic plaques have better hearing gain. Although surgery is still controversial in tympanosclerosis; it is the most effective treatment till new effective medication is discovered.
