Results of End-To-Side Hypoglossal-Facial Nerve Anastomosis in Facial Paralysis after Skull Base Surgery.

INTRODUCTION: The primary aim of facial reanimation surgery is to restore tone, symmetry, and movement to the paralyzed face. Hypoglossal-facial end-to-side anastomosis provides satisfactory facial reanimation in the irreversible proximal injury of the facial nerve. This study discussed the facial function results of end-to-side anastomosing of hypoglossal nerve to facial nerve when the injury occurred during skull base surgery. MATERIALS AND METHODS: The present study enrolled a total of 10 patients who underwent end-to-side hypoglossal-facial nerve anastomosis after facial nerve paralysis due to skull base surgery. The data of the patients were gathered from hospital records, pictures, and movies during the 18 months of follow-up. RESULTS: At the 18 months of follow-up, seven (70%) and three (30%) patients were reported with grades III and IV of the House-Brackmann scoring system, respectively. In total, out of the seven grade III patients, six subjects underwent early anastomosis (within the first year of the paralysis). On the other hand, among patients with grade IV, two subjects had late anastomosis. CONCLUSION: It seems that early end-to-side hypoglossal-facial anastomosis can be a favorable surgical option with good facial function results for reanimating the facial function of patients with facial paralysis following skull base surgery.

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. 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.

Prediction of stapes footplate thickness based on the level of hearing loss in otosclerosis.

During surgical treatment of a patient with otosclerosis, the probability of success depends in large part on the extent of the surgeon's experience. Therefore, predicting the preoperative severity of disease may help determine the choice of surgeon based on how experienced the surgeon should be. We conducted a study to evaluate the relationship between hearing thresholds and footplate thickness in otosclerosis patients who underwent stapes surgery. We used a qualitative method for measuring footplate thickness that was based on the simplicity or difficulty of opening the footplate. Our study population was divided into two groups; group 1 was made up of 66 patients whose footplates were easily opened with low pressure or with repeated motions by hand, and group 2 was made up of 14 patients whose footplate was either opened by drilling or not opened because it had been obliterated. We found that the patients in group 2, who had more severe disease, had significantly higher air- and bone-conduction thresholds than did the patients in group 1. According to our findings, otosclerotic patients with high air- and bone-conduction thresholds generally have more severe disease and thus require a more experienced surgeon.
