RESUMO

OBJECTIVE: To reveal the incidence and predictive parameters of occult cervical lymph node metastasis (LNM) in patients with cN0 laryngeal squamous cell cancer (LSCC) who underwent surgery as definitive treatment. METHODS: Patients with cN0 laryngeal cancer who had undergone elective neck dissection together with partial or total laryngectomy between January 2006 and November 2020 were retrospectively analyzed. Clinical and histopathologic predictors of occult metastasis were also analyzed. Follow-up data were used to obtain recurrence and survival analysis. RESULTS: A total of 86 patients with a mean age of 62.5 years were included in the study. Occult LNM was detected in 15 (17.4%) patients. Tumor grade, pT stage, thyroid cartilage invasion, and extralaryngeal extension were found to predict occult neck metastasis in univariate analysis. The mean follow-up time was 60.7 months and in the survival/recurrence analysis, pT stage, tumor location, tumor grade, presence of occult metastasis, pre-epiglottic space involvement. and extralaryngeal extension were found to predict poorer outcome. CONCLUSION: Overall occult LNM is low (17.4%) in N0 laryngeal cancer, but the presence of LNM is a poor prognostic factor. Correct determination of the neck status and proper treatment is crucial. The incidence of LNM is very low in T1-T2 stages and well-differentiated tumors. The "wait and see" strategy may be applied in T1-T2 cases as well as selected T3 cases with well-differentiated tumors.

RESUMO

Auricular hematoma is commonly seen in ear nose and throat clinical practice and mostly caused by blunt trauma as a result of traffic accident, wrestling, boxing etc. If hematoma does not discharge, blood supply of the cartilage fails and this results with the necrosis of the auricular cartilage. Incision and drainage of the hematoma is the cornerstone of the surgical treatment and simple compression methods are limited in terms of their ability to eliminate the empty space. Various techniques have been described for the elimination of the death space such as; dental rolls, cotton bolsters, buttons, silastic sheets, etc but compression materials may be insufficient to apply this pressure because of irregular shape of auricle. Resolving these problems, the authors have used thermoplastic splint as a compressive material at 7 patients for elimination of the death space in auricular hematoma treatment.

RESUMO

OBJECTIVES: The aim of our study was to investigate the effects of folic acid on cisplatin-induced ototoxicity. MATERIALS AND METHODS: Thirty Wistar albino rats were divided into five groups. Group I received intraperitoneal cisplatin (IP) 10 mg/kg/day and IP folic acid 10 mg/kg/day; Group II received IP cisplatin 10 mg/kg/day and IP physiological saline; Group III received IP cisplatin 10 mg/kg/day and intratympanic (IT) folic acid 0.15 mL/day; Group IV received IP cisplatin 10 mg/kg/day and IT physiological saline; and Group V received IT folic acid 0.15 mL/day. Before and after drug administration, plasma homocysteine, folic acid levels, and auditory brainstem evoked responses (ABR) were measured. The rats were then sacrificed, and the inner ears were processed for electron microscopy. RESULTS: The differences of ABR thresholds in Group I compared to Group II were significantly smaller at 4 kHz, 8 kHz, and 16 kHz, whereas they were smaller but not statistically significant at 12 kHz in ABR. The differences of ABR thresholds in Group III compared to Group IV were significantly smaller at 12 kHz, and smaller but not statistically significant at 4 kHz, 8 kHz, and 16 kHz. Cisplatin treatment resulted in the degeneration of the cells of the organ of Corti, stria vascularis, and spiral ganglion. The cells of the organ of Corti, stria vascularis, and spiral ganglion showed a partially preserved morphology in both Group I and Group III. CONCLUSION: Our study results suggests that folic acid is a potential agent in preventing cisplatin-induced ototoxicity.

RESUMO

Nose bleeding is a common situation seen in otorhinolaryngological practices. One of the greatest risk factors in nose bleeding is the use of anticoagulant medicine. With the medicine developed in recent years, the risk of nose bleeding due to the frequent use of anticoagulant and antiagregant is gradually increasing.The purpose of this study is to determine the effects of especially new-generation anticoagulants on nose bleeding. In addition, the use and complications of new-generation anticoagulants and antiagregants have been compiled in light of information obtained from the literature.Three hundred forty patients whose follow-up is conducted by the cardiology department and who use oral antithrombocytic medicine have been included in the study. It has been determined that 15% of these patients use new-generation oral anticoagulants (Rivaroksaban, apiksaban, dabigatran, danaparoid) and the other patients are treated with conventional antithrombocytic treatment (Aspirin, Warfarin, Enoksaparin sodium). The rate of nose bleeding in patients who use classical anticoagulants has been observed to be 28%. In 30 of these patients who had nose bleeding, while cauterization and buffering by otorhinolaryngology specialists, major intervention has not been necessary for any of the patients. While bleeding has been observed in 26% of the patients who use new-generation anticoagulants, bleeding that required operational intervention has taken place in 2 patients. Bleedings have been stopped surgically through a large number of cauterization and buffering.While the new-generation anticoagulants cause lower rate of bleeding, it has been observed that controlling these bleedings is more difficult.

RESUMO

INTRODUCTION: Septal deviation is a common disease seen in daily otorhinolaryngology practice and septoplasty is a commonly performed surgical procedure. Caudal septum deviation is also a challenging pathology for ear, nose, and throat specialists. Many techniques are defined for caudal septal deviation. OBJECTIVE: To evaluate the effectiveness of caudal septal extension graft (CSEG) application in patients who underwent endonasal septoplasty for a short and deviated nasal septum. METHODS: Forty patients with nasal septal deviation, short nasal septum, and weak nasal tip support who underwent endonasal septoplasty with or without CSEG placement between August 2012 and June 2013 were enrolled in this study. Twenty patients underwent endonasal septoplasty with CSEG placement. The rest of the group, who rejected auricular or costal cartilage harvest for CSEG placement, underwent only endonasal septoplasty without any additional intervention. Using the Nasal Obstruction Symptom Evaluation (NOSE) and Rhinoplasty Outcome Evaluation (ROE) questionnaires, pre- and post-operative acoustic rhinometer measurements were evaluated to assess the effect of CESG placement on nasal obstruction. RESULTS: In the control group, preoperative and postoperative minimal cross-sectional areas (MCA1) were 0.44±0.10cm2 and 0.60±0.11cm2, respectively (p<0.001). In the study group, pre- and postoperative MCA1 values were 0.45±0.16cm2 and 0.67±0.16cm2, respectively (p<0.01). In the control group, the nasal cavity volume (VOL1) value was 1.71±0.21mL preoperatively and 1.94±0.17mL postoperatively (p<0.001). In the study group, pre- and postoperative VOL1s were 1.72±0.15mL and 1.97±0.12mL, respectively (p<0.001). Statistical analysis of postoperative MCA1 and VOL1 values in the study and the control groups could not detect any significant intergroup difference (p=0.093 and 0.432, respectively). In the study group, mean nasolabial angles were 78.15±4.26° and 90.70±2.38°, respectively (p<0.001). CONCLUSION: Endonasal septoplasty with CESG placement is an effective surgical procedure with minimal complication rate for subjects who have a deviated, short nasal septum and weak nasal tip support.

RESUMO

BACKGROUND: Nasal packing is frequently used after surgical interventions to prevent bleeding and synecchia formation and for the treatment of diseases such as epistaxis. One of the most morbid complications of nasal packing applications is the toxic shock syndrome (TSS). Owing to the microbiological structure of nasal mucosa, antibiotics are administered to all patients who are applied nasal packages for prevention of TSS. AIM: The aim of this study is the evaluation of microbiological and histopathological changes taking place in nasal mucosa with nasal packing containing probiotics. METHODS: Three groups were formed with 6 rats in each group. The nasal packings with the same characteristics were applied to nasal cavities of rats in all 3 groups. In group 1, only nasal packs were used. Probiotics or parenteral antibiotics were not used. In group 2, parenteral antibiotics were used along with nasal packs. In group 3, nasal packs with probiotics containing Lactobacillus strains were applied. No parenteral antibiotics were used. After 3 days packages were removed and nasal cavity was irrigated with saline. Both packages and irrigation materials were analyzed for microbiological content. After scarification, nasal and paranasal structures were examined for histopathological changes. RESULTS: In group 3 statistically the total bacteria load was significantly lower in comparison to the other groups. However, in the histopathological evaluation of the mucosa of rats in group 3, bleeding and inflammation findings were significantly higher statistically. CONCLUSIONS: It has been determined that the total microbiological load significantly decreases with the application of packing containing probiotics. So, the use of probiotics along with nasal packings is promising to prevent unnecessary use of medications.

RESUMO

OBJECTIVE: To evaluate the effectiveness of enoxaparin sodium (ES) on experimentally-induced myringosclerosis in rats. MATERIALS AND METHODS: Twenty Wistar albino-type rats weighing up to 250-300 g each were randomized into four groups containing five rats each and were then bilaterally myringotomized. The control group (n=5) received intratympanic serum physiologic injections, whereas ES2 (n=5), ES4 (n=5), and ES6 groups (n=5) received intratympanic ES of 2000 IU, 4000 IU, and 6000 IU, respectively, for 10 days after myringotomy. Rats were sacrificed at 60 days after intratympanic application and were then prepared for histopathologic evaluation. RESULTS: As for tympanic membrane hyaline degeneration, there were statistically significant differences among the control, ES2, ES4, and ES6 groups (p<0.05). As for fibrosis formation on tympanic membranes, a statistically significant difference was observed among the control and study groups; however, although not statistically significant, the formation of fibrosis was slowed down in the ES2 and ES4 groups compared with the control group. The control and study groups did not show any significant difference for calcification, hyperemia, and tympanic membrane thickening (p>0.05). CONCLUSION: Although our study and control groups comprised limited number of animals, and only one parameter demonstrated a statistically significant difference between the groups, ES may have an ameliorating effect on myringosclerosis induced by myringotomy in the tympanic membranes of rats. ES proved to be effective in the prevention of hyaline disc formation. Further studies should be conducted for better understanding of the effects of low-molecular-weight heparin (LMWH) (i.e., enoxaparin) on myringosclerosis.

RESUMO

OBJECTIVE: This study aimed to investigate the articles regarding rhinology published in national otorhinolaryngology journals between 2010 and 2015 according to the manuscript type, headline, citation city, and institution, as a reference for studies that will be designed in the future. METHODS: Articles published on rhinology between 2010 and 2015 in national otorhinolaryngology journals were searched through websites of journals. The names of the journals, subjects of the manuscripts, manuscript type, citation city and institution, and manuscript language were recorded. RESULTS: In this study, 890 articles were reviewed in 6 national otorhinolaryngology journals. Of these, 274 were regarding rhinology and 129 (47%) and 117 (42.7%) were original articles and case reports, respectively. Of the 274 articles, 21 (7.7%) and 5 (1.9%) were review and animal studies, respectively, and 2 (0.7%) articles defined surgical technique. Most frequently studied topics were benign tumors and inflammatory diseases of the paranasal sinuses. CONCLUSION: The ratio of case reports was relatively high in national rhinology publications. In future, smell and taste disorders, skull base surgery, and nasal physiology-related to Rhinology may be innovative research areas.

RESUMO

OBJECTIVE/HYPOTHESIS: To evaluate the spatial hyoid bone position and the oropharyngeal air column volume after infrahyoid muscle sectioning as a single procedure. STUDY DESIGN: Animal experiment. METHODS: Six adult New Zealand rabbits underwent sternohyoid, omohyoid, and thyrohyoid muscle sectioning for infrahyoid release. Preoperative and postoperative computed tomography scans were obtained and transferred to the Mimics software program. By using the program, preoperative and postoperative three-dimensional models of the spatial hyoid bone position and the oropharyngeal air column volume were determined and compared. RESULTS: After the surgical intervention, it was found that the hyoid bone significantly moved to a more anterior (P = .028, P = .046), and superior (P = .028, P = .028) position. The preoperative mean oropharyngeal air column volume (618.88 ± 176.54 mm(3) ) also increased after infrahyoid muscle sectioning (797.01 ± 155.33 mm(3) ). and this change was also statistically significant (P = .028). CONCLUSIONS: Infrahyoid release improves oropharyngeal air column volume, as the hyoid bone moves to a more anterior and superior position after this operation in an animal model. However, additional animal and human studies are necessary to evaluate a possible therapeutic role of this procedure. LEVEL OF EVIDENCE: NA.

RESUMO

Biofilm formation is present in the middle-ear mucosa of chronic otitis media (COM) patients and COM is a biofilm-related disease. Biofilms are organized and complex communities in which bacteria communicate to each other and gain tremendous advantages. In this unique structure, bacteria can diffuse nutrients, gain resistance to antimicrobials agents and host defense mechanisms. Recently bacterial biofilms have been proven to be important in infectious diseases of head and neck region. A prospective case-control study was conducted. The study group comprised of patients with chronic otitis media and patients undergoing surgery for cochlear implantation was involved in the control group. Study group also divided to subgroups SSA and SSB according to history of ear discharge within last six months. Direct microscopy (DM) and transmission electron microscopy (TEM) were used to assess presence of biofilms. Totally 19 patients, 10 with ear discharge history within last 6 months and 9 without discharge comprised the study group. Control group comprised of 9 patients undergone cochlear implantation. In all of the patients with ear discharge history and in two of the patients without ear discharge history, biofilm formation was detected by both DM and TEM. All control group members were free of biofilm formation. The differences were statistically significant between study and control groups (p = 0.002) and between study subgroups (p < 0.001); but not significant between study subgroup without ear discharge history and control group (p = 0.470). In the middle ear mucosa of patients with chronic otitis media, biofilm formation is common, especially when ear discharge history is present.

RESUMO

OBJECTIVES: The aim of this study was to determine safety, pain perception, and the factors that may affect pain perception in patients undergoing certain otorhinolaryngologic procedures under local anesthesia with sedation. DESIGN: Prospective clinical study. SETTING: Tertiary care academic medical centre. METHODS: Two hundred thirteen patients operated on under local anesthesia with sedation were included in the study. A visual analogue scale (VAS) and a questionnaire were employed to measure pain perception during surgery and evaluate possible pain-related variables. RESULTS: The mean VAS values were 2.86 (+/-1.84) for the myringoplasty group, 2.54 (+/-1.76) for the otosclerosis surgery group, 1.70 (+/-1.25) for the somnoplasty group, 1.00 (+/-0.94) for the oral biopsy group, 2.15 (+/-1.49) for the inferior turbinate radiofrequency reduction (ITRR) group, 3.47 (+/-2.18) for the septoplasty plus ITRR group, 5.56 (+/-2.01) for the septorhinoplasty group, 4.94 (+/-2.16) for the open technique septoplasty group, and 3.30 (+/-1.87) for the septoplasty group. No variable was shown to affect pain perception when all patients were evaluated in common. When surgical procedures were evaluated individually, the level of acquaintance of patients in the myringoplasty group (p=.007) and operative time for the septoplasty group (p<.001) were found to independently affect pain perception. CONCLUSIONS: Given that septorhinoplasty and open technique septoplasty are found to be more painful, it is advisable to perform these procedures under general anesthesia. To increase the level of acquaintance of patients and to shorten operative time as possible may be helpful for minimizing pain perception.
