This study was carried out to compare the postoperative results of trans-septal suturing with the anterior Merocel packing technique. The study involved 697 patients who underwent septoplasty. Following surgery, patients were randomly divided into two groups, one with trans-septal suturing and the other with Merocel packing. Patients were asked to record pain levels using a visual analogue scale. Postoperative symptoms and complications were compared. A total of 697 nasal operations were evaluated in the postoperative period considering pain, bleeding, haematoma, septal perforation synechiae and septal perforation. The results for haemorrhage, haematoma, synechiae and perforation were not statistically different (p > 0.05) between groups. In contrast, the level of postoperative pain in patients undergoing trans-septal suturing was significantly less than in the group who received Merocel packing (p < 0.05). Patients with Merocel packing had significantly more pain and nasal discomfort when assessed 1 week after intervention. Therefore, the trans-septal suturing technique may be the preferred option to provide higher patient satisfaction.

The possibility of inducing an iatrogenic facial weakness was also evaluated. Both the surgeon and the majority of patients were pleased with the quality of anesthesia and little adverse effects occured as a consequence of local anesthesia itself.

Restenosis which count for the most common causes of failure in endoscopic dacryocystorhinostomy (EDCR) reduces the success rate. We intended to make a large fistula, potentially minimizing granulation tissue, and synechiae by means of creating a large bony ostium and preserving mucosal flaps and intubation with silicone tube (STI). In this study, long-term follow-up results of EDCR with mucosa preservation were discussed. 126 patients underwent endonasal DCRs from January 2004 to March 2009. A large ostium was created preserving mucosa; nasal and lacrimal flaps were approximated and the new ostium was stented with silicone tube. Surgical success rate was 93 % with STI and with preservation of nasal and lacrimal flaps. In conclusion, EDCR is an easy surgical procedure with low complication rates. Intranasal pathologies can also be corrected in the meantime. Success depends on creating a large bony ostium and preventing restenosis. EDCR preserving nasal and lacrimal flaps with STI is recommended as an alternative procedure in chronic dacryocystitis with high success rates.

Three patients with isolated agenesis of the uncinate process and 27 patients with 43 maxillary sinus hypoplasia variations were recruited. The frequencies of sinusitis episodes and radiological findings were compared between patient subgroups. In all, 23 type I maxillary sinus hypoplasia, 13 type II maxillary sinus hypoplasia and 7 type III maxillary sinus hypoplasia variations were detected. Patients with isolated agenesis of the uncinate process underwent antibiotic treatment an average of 7 times per year, whereas those with types I, II and III maxillary sinus hypoplasia were treated 1.57, 3.22, and 5.75 times per year, respectively, over a 5-year period. The antibiotic treatment frequency for patients with isolated agenesis of the uncinate process was significantly higher than for those with types I and II maxillary sinus hypoplasia. Isolated agenesis of the uncinate process seems to play a stronger role than types I and II maxillary sinus hypoplasia in the pathophysiology of chronic sinusitis.

Transient evoked otoacoustic emissions were recorded before and after autologous serum application. Apoptotic cells were identified in the organ of Corti, spiral limbus and spiral ganglion by the terminal deoxynucleotidyl transferase-mediated dUTP nick-end labelling (‘TUNEL’) method.Results:Transient evoked otoacoustic emission responses at 1, 1.4 and 2.8 kHz improved without significance after autologous serum application in group A (p > 0.05). A significantly protective effect of autologous serum was determined at 4 kHz in group B (p < 0.05). There were significantly fewer apoptotic cells at the spiral limbus in the therapeutic and protective groups compared to the control group (p < 0.05).Conclusion:Autol...

Psychological criteria are as important as audiological criteria in patient selection to achieve success in tinnitus therapy. Objective: To assess the effectiveness of wide-band acoustic signals based on tinnitus frequency for each individual patient, delivered through a hearing-aid to aid in relief of tinnitus (Tinnitus masking therapy-TMT). Tinnitus handicap scales were used to assess the degree of relief both in 42 patients with normal hearing or some degree of hearing loss. Results: The relief from annoyance was 55.9% and decrease of negative effect on life was 67.2% after three months of treatment. Total rate for any degree of relief was 79.3% in normal hearing group, where in hearing-loss group it remained at 61.2%. Emotional, social and hearing-related scores were similar evaluated by different types of questionnaires. Intensity of masking noise was decreased gradually in all pa...

Environmental protection is considered to be a broad spectrum activity. Economic and social activities should be planned and implemented in the framework of environmental and sustainability principles. A significant impact on improving the quality of the environment is the implementation of these principles in the economic activities of both businesses and individual municipalities. The growing importance of environmental protection has an impact on all business activities, not only in the Slovak Republic, but also in all the advanced world economies. Businesses need to adjust to this new trend if they want to achieve competitiveness in the field of sustainable production and environmentally sound production of their products and services on a domestic and, in particular, globalized foreign market. The aim of the paper is to analyze the costs incurred for the protection of the environment in SR conditions.

A total of 84 children (42 children with hearing impairment and 42 healthy children) and their parents were included. The emotional, behavioural, peer and school-related problems were significantly higher, and self-esteem levels were significantly lower in the case group compared to the healthy children. We also determined that the parents of children with hearing impairment had overprotective and authoritarian parenting styles compared. The findings showed that there was a significant correlation between the emotional problems of children and the overprotective and authoritarian parenting style. These findings indicated that the intervention should not focus solely on the existing disabilities of these children. It also pointed at the importance of the parental attitudes in both the treatment and protection of mental health.

Bu doku normal bir görünümde olsa da, fonksiyonları değişiktir. Çoğunlukla iyi huylu tümörlerdir. Neoplazmların aksine hamartomlar devamlı olarak çoğalma yeteneklerinin olmaması, kendilerini sınırlayan bir çoğalma ile sonuçlanırlar. Hamartomlar akciğer, karaciğer, böbrek, intestinal sistemden köken alma eğilimindedirler. Ancak üst solunum yollarında çok sık görülmezler. Nazal hamartomlar (NH) nadir olmakla birlikte yaygın olarak nazal septum ya da nazal kavite kaynaklıdırlar. Histolojik olarak yaygın alt tip serömüköz bezden değil solunumsal epitelden orijin alan glandular elemanların varlığıyla karakterize olan Respiratuar Epitelial Adenomatoid Hamartom (REAH)'dur. Bu özellik onları glandular elemanların serömüköz bezden orijin aldığı inflammatuar poliplerden ayırır. Hamartomaların etiyopatogenezi bilinmemektedir. Bu sunumumuzda REAH tespit edilen bir olgumuz ve nazal kaviteden orjin alan bu tümör tipinin literatürü gözden geçirilecektir.

This study was conducted between November 2007 and February 2008 on 36 New Zealand rabbits aged four-to-six months and weighing 1.5 to 2 kg. Subjects were divided into six equal groups. The first group was defined as the control group. Next four groups consisted of subjects where RF or laser was either applied transmucosal or directly to the cartilage. Cottle's method was used in the sixth group. Histopathological and radiological changes were investigated in each group. Histopathological changes in mucosa were not significantly different from those of control group. However, post-intervention changes in cartilage were significantly different, compared to the control group. The highest mucosal and submucosal reaction and damage in cartilage with ossification was found in Cottle group. It was found that radiofrequency wa...

With the use of septal mucosal quilting sutures to stabilize mucosal flaps, many surgeons have abandoned using nasal packing. This technique also helps to close any mucosal tears and may help prevent septal perforation.

Otologic manifestations may be seen during the course of the disease, however, they are not frequently seen as the first and only presenting feature. The presence of anticytoplasmic antibodies versus neutrophil polymorphonucleate granules (c-ANCA) is highly specific for the diagnosis of WG, being positive in 97% of the cases. The early diagnosis and the timely medical treatment result in high rates of remission of this potentially lethal disease. In this article, we report a case of WG presenting with acute serous otitis media, progressing to suppurative otitis media and granulomas as the first and only symptom, which was refractory to medical therapy during follow-up and which was diagnosed with further examination.
