Stapes Management in Tympanosclerosis
Background: Stapes management in tympanosclerosis has always been controversial. There are evidences supporting stapes mobilization, but there are concerns regarding refixation and recurrence of conductive hearing loss; therefore, supporting stapedectomy.Methods: In this retrospective study, clinical records, operative notes, and audiologic data of patients with stapes fixation (1994–2011) were analyzed. Audiometric findings are reported according to the recommendations of the Committee on Hearing and Equilibrium 1995 Guidelines for the Evaluation of Results of Treatment of Conductive Hearing Loss.Results: In the present study, 66 patients were enrolled (23 male, 43 female). Stapedectomy and stapes mobilization both had good hearing results (12.1 dB vs. 10.6 dB reduction in ABG) and there was no significant difference. Overall, 63.6% of patients had achieved good results (mobilization: 57.9%, stapedectomy: 71.4%). The difference in success rate between the two groups was not statistically significant.Conclusions: Stapedectomy and mobilization of stapes both seem to be efficacious and safe in the treatment of stapes involvement in tympanosclerosis. The hearing improvement is long lasting in both procedures
Results of Type I Tympanoplasty Using Fascia with or without Cartilage Reinforcement: 10 Years’ Experience
Introduction: There remains controversy about the optimal kind of graft to repair tympanic membrane. The purpose of this study was to evaluate the anatomical and auditory outcomes of type I tympanoplasty using fascia with or without cartilage reinforcement. Â Materials and Methods: This retrospective cohort study was conducted from 2005 to 2015. All cases were surgically treated by a single surgeon. We excluded cases in which the etiology of chronic otitis media was cholesteatoma. According to the use of cartilage reinforcement in the posterosuperior part of the graft, patients were divided into two groups, and the results of anatomical and auditory evaluation were compared between the two groups. The anatomical outcome was grafting success and the auditory outcome was improvement of air bone gap (ABG). Â Results: A total of 320 patients were classified in Group A (tympanoplasty with fascia temporalis only) and 346 were in Group B (tympanoplasty with cartilage reinforcement). All patients were followed for at least 2 years. The overall success rate in the two groups was 91.6% and 93.4%, respectively (P=0.3). The most common cause of failure in the two groups was re-perforation (5.6% and 3.8%, respectively). The improvement of ABG in two groups was 18.5 dB and 3.2 dB, respectively. The difference between two groups was statistically significant (
Large Lipoma of the Larynx: A Case Report
Fewer than 15% of lipomas occur in the head and neck. Lipomas of the larynx are very rare benign laryngeal tumors (0.6%). To date less than 100 case of laryngeal lipoma have been reported in the literature.Clinical manifestation include progressive horseness, dyspnea, and even dysphagia. In the direct exam smooth or pedunculated mass is seen in the larynx and sometimes if tumor is large enough a mass palpated in the neck. In the computed tomography (CT) low attenuation mass is seen. Treatment of laryngeal lipoma consists of endoscopic removal or external surgical approach depending on tumor size. The authors present a case of laryngeal lipoma that involved the true vocal cord. The following is a report of a single case of laryngeal lipoma, Including esteroboscopy, radiologic and intraoperative finding as well as review of the literature
The Effect of Intratympanic Dexamethasone with Oral Prednisolone as a Primary Treatment in Idiopathic Sudden Sensorineural Hearing Loss
Introduction:
Sudden sensorineural hearing loss (SSNHL) is a true emergency that must be diagnosed and treated immediately. The purpose of this study is to compare the efficacy of treatment with intratympanic dexamethasone plus oral prednisolone daily or every other day with that of treatment with oral prednisolone alone.
Materials and Methods:
Sixty-three patients with SSNHL that had been present for less than 10 days prior to the start of treatment were randomly allocated to three different groups. Patients in group A were treated daily with oral prednisolone 1 mg/kg for 10 days plus intratympanic dexamethasone 2 mg for the first 3 days of treatment. Patients in group B were treated every other day with oral prednisolone 1 mg/kg for 10 days with the addition of intratympanic dexamethasone 2 mg for the first 3 treatments. Patients in group C were treated daily with oral prednisolone 1 mg/kg alone for 10 days. Audiometric parameters including pure tone audiometry (PTA), speech reception threshold (SRT), and speech discrimination score (SDS) were assessed on days 1,5, and 10.
Results:
There was a significant improvement in PTA, SRT and SDS in each group over the 10 days but the greatest improvement was seen in the SRT measurements of group A in comparison with group B (19.81 ± 2.15, P=0.04) and C (26.26 ± 0.08, P=0.01). The difference in SRT between groups B and C was not statistically significant.
Conclusion:
The administration of intratympanic dexamethasone 2 mg daily for 3 days has an additive effect to that of 10 days of oral prednisolone 1 mg/kg in the treatment of SSNHL
Prophylactic Antibiotics in Otolaryngologic Surgeries: From Knowledge to Practice
Introduction:
The management and use of antimicrobial drugs has clinical, economic, and environmental implications. In many countries, antimicrobial drugs are the most frequently prescribed therapeutic agents. Therefore, health-care policy should focus on how to establish a rational attitude toward antibiotics. This study was performed to investigate antibiotic usage as a prophylactic regimen in head and neck surgeries.
 Materials and Methods:
This study was a retrospective case series. Patients undergoing otolaryngology surgeries in a tertiary referral otolaryngology center were included. Members of operating room staff that were unaware of the study objectives collected patients’ data using a questionnaire that contained information regarding general medical condition, disease, surgical procedure, and prophylaxis regimen and duration.
Â
Results:
Excluding infected patients, we studied 1349 patients during a four-month period who needed prophylactic antibiotics. A total of 34 different types of surgical procedures were performed. Out of the total number of patients, 503 (37.0%) received a parenteral antibiotic directly before surgery. The main antibiotics used before surgery were cephalosporins (94.9%). All of the 1349 patients were administered antibiotics after the procedure. These antibiotics where given with a mean number of doses of 4.81 (range: 1–68), and also consisted of mostly cephalosporins.
Conclusion:
Our results indicate that prophylactic antibiotics were being significantly misused in a tertiary referral center of a university hospital. Although teaching the principles of prophylaxis to physicians is important, we think that finding a way to bring this knowledge to practice is more important
Evaluation of the Correlation between CD44, Tumor Prognosis and the 5-Year Survival Rate in Patients with Oral Tongue SCC
Introduction: 90% of the tumors in the head and neck are squamous-cell carcinomas (HNSCC), which have overall 5- year survival rate between 50% -60%. CD44 has been shown to be associated with the prognosis.  Materials and Methods: Biopsy specimens of 51 patients with oral tongue SCC were evaluated by Immunohistochemistry (IHC) for the CD44 antibody.  Results: There was no significant correlation between CD44 and survival (P=0.77), age (P=0.4), CD44 and lymph node metastasis (P=0.87), sex (P=0.947), smoking (P=0.287) and tumor size (P=0.813). However, there was significant correlation between smoking and survival.  Conclusion: There are widespread discrepancies among the findings in the literature regarding the prognosis of CD44 expression in OCSCC. Our study shows that the expression of CD44 is not a marker of aggressive behavior in oral tongue SCC. Consequently, CD44 cannot be considered as handy tool to establish the tumor behavior, prognosis and 5- year survival rate of these tumors
