Otolaryngologists are sometimes confronted with various complications. They may be minor or sometimes they can be major, and rarely fatal. Some complications can be prevented, but some are unavoidable. Five cases of major complications, which occurred during or after routine rhinologic surgery, are presented. Two patients died of toxic shock syndrome: one patient after endoscopic sinus surgery (ESS) and the other patient after closed nasal bone reduction. One patient died of acute myocardial infarction during the recovery of anesthesia after uneventful ESS. One patient had a lidocaine shock, which required treatment in the intensive care unit. One patient had a transient unilateral blindness after intranasal steroid injection. Though the 3rd and 4th cases of complications were unavoidable, the others could have been prevented if precautions had taken place. The presumed pathophysiology, possible prevention measures, and their implications in routine otolaryngologic surgery are discussed.

This report was designed to investigate a rare case that brachialis tear and hematoma caused by acute elbow posterior dislocation. We studied a 20-year-old male patient with right elbow joint pain after outstretched injury. Physical examination showed instability of hright elbow joint and simple radiography indicated a posterolateral dislocation of right elbow joint. Computed tomography taken after closed reduction using Parvin technique revealed a few small bone fragment located on posterior humerus capitulum. Magnetic resonance imaging showed complete tear of brachialis and anterior articular capsule with hematoma. The patient was managed with long arm splint and hinge brace for an elbow dislocation with brachialis rupture and hematoma. The elbow joint range of motion was recovered to be in a normal range, and pain was diminished. There are few reported cases of acute elbow posterior dislocation combined with brachialis rupture and hematoma. The patient showed good clinical outcome after conservative treatment.

A Schwannoma is a tumor originating from the neural sheath of Schwann cells, and is also known as a neurilemmoma, neurinoma or fibroblastoma. It can be either a benign or malignant tumor arising from the associated nerve sheath. Here, a case of a Schwannoma, originated from the obturator nerve of the pelvic cavity, in a patient with urinary frequency is reported, with a brief review of the literature.

Purpose: This study aimed to assess the clinical outcome and safety of holmium laser enucleation of the prostate (HoLEP) following transrectal ultrasound-guided prostate biopsy (TR biopsy) in the treatment of benign prostate hyperplasia. Materials and Methods: We retrospectively analyzed data from 556 patients who underwent HoLEP between 2014 and 2021. The patients were categorized into six groups: Group 1-A (n=45) underwent HoLEP within four months post TR biopsy. Group 1-B (n=94) underwent HoLEP more than four months post TR biopsy. Group 1-C (n=120) underwent HoLEP after a single TR biopsy. Group 1-D (n=19) underwent HoLEP after two or more TR biopsies. Group 1-total (n=139, group 1-A+group 1-B or group 1-C+group 1-D) underwent HoLEP post TR biopsy. Group 2 (control group, n=417) underwent HoLEP without prior TR biopsy. We examined perioperative parameters, safety, and functional outcomes. Results: The age, body mass index, International Prostate Symptom Score (IPSS), uroflowmetry, and comorbid diseases between group 1-total and group 2 were comparable. However, group 1-total exhibited significantly elevated prostate-specific antigen levels and larger prostate volumes (p<0.01). Perioperative factors like enucleation time, enucleation weight, and catheterization duration were notably higher in group 1-total (p<0.01). All groups showed significant improvements in IPSS, postvoid residual urine, and maximum flow rate during the 1-year postoperative period (p<0.05). The rates of postoperative complications were similar between group 1-total and group 2. Conclusions Enucleation time and catheterization duration were significantly longer in the TR biopsy group. However, postoperative complications were not significantly different between TR biopsy and non-TR biopsy groups.

PURPOSE: Numerous studies of the effect of tadalafil on sexual function have been performed. However, its effects on lower urinary tract symptoms (LUTS) are unclear. Therefore, the long-term effects of tadalafil on the improvement of LUTS as well as erectile dysfunction were examined. MATERIALS AND METHODS: 69 patients who visited our hospital reporting LUTS and erectile dysfunction as chief complaints were divided into 3 groups. Group 1 received 10 mg/day alfuzosin (39 patients, age: 61.36+/-8.69), group 2 received 10 mg/day alfuzosin and 5 mg/2 day tadalafil (15 patients, age: 58.00+/-7.91), and group 3 received 5 mg/2day tadalafil (15 patients, age: 54.70+/-10.01). Drugs were administered for 24 weeks. At before and 12 weeks and 24 weeks after drug administration, maximum flow rate, IPSS, quality of life, IIEF-5, and self satisfaction were measured and analyzed. The SPSS 14.0 was used as statistical software, and the data were validated using ANOVA. RESULTS: Between pre- and post-administration, the maximum flow rate significantly increased in all groups (p<0.05). The IPSS of groups 1 and 2 were significantly reduced (p<0.05). Quality of life significantly decreased in group 3 (p<0.05). IIEF-5 for groups 2 and 3 significantly increased (p<0.05). Self satisfaction significantly decreased in groups 2 and 3 (p<0.05). CONCLUSIONS: When alfuzosin and tadalafil were administered together for 24 weeks, both LUTS and erectile dysfunction improved significantly. In the group administered tadalafil alone, LUTS improved. Thus, administration of tadalafil for 24 weeks is able to improve not only erectile dysfunction but also LUTS.

PURPOSE: The aim of this study was to evaluate the efficacy and safety of a herbal formula that mainly consists of Cornus officinalis for treating erectile dysfunction. MATERIALS AND METHODS: Eighty patients suffering with erectile dysfunction were enrolled in this randomized, double-blinded, placebo-controlled study. The average duration of erectile dysfunction of the herbal formula group(n=40) vs. the placebo group(n=40) were 19.33+/-18.13 months vs. 19.33+/-25.62 months, respectively. The safety variables we examined were the history, physical examination, vital signs, EKG, clinical laboratory tests and hormonal tests. Efficacy assessments included the International Index of Erectile Function(IIEF), the sexual encounter profile(SEP) diary and Global Assessment Questions(GAQ). RESULTS: No significant changes in the laboratory values, hormone tests and blood pressure were observed in both groups. In comparison with the placebo group(6.57+/-11.72), the herbal formula group experienced a significant improvement of the IIEF(11.13+/-11.83)(p<0.05). When the herbal formula and placebo groups were divided by age and the IIEF score (age: 50 years and IIEF: 42) and then compared, the low IIEF group(IIEFor=50) of the herbal formula group significantly improved their IIEF score(p<0.05). The herbal formula group significantly improved their GAQ score(p<0.05). The herbal formula was well tolerated. The common adverse events were headache(2.5%) and nausea(5%). CONCLUSIONS: In conclusion, the herbal formula that mainly consists Cornus officinalis was not only effective at improving erectile function, but it was also safe for the treatment of erectile dysfunction.

PURPOSE: Cocoa has antihypertensive activity, improves cerebral blood flow, and is an antioxidant. We evaluated the effect of cocoa extract on penile erection using the relaxation of the corpus cavernosal tissue in rat. MATERIALS AND METHODS: We used male 8-week-old Sprague-Dawley rats weighting 250-350 g divided into three groups: corpus cavernosal tissue with the endothelium (group 1), tissue without the endothelium (group 2), and endothelium pretreated with L-NAME (group 3). Changes in isometric tension were examined in an organ bath. Aortic tissues were divided into three groups and treated in similar experiments simultaneously. RESULTS: Cocoa extract dose-dependently relaxed corpus cavernosal tissue pre-contracted by phenylephrine (10-6). In group 1, cocoa extract (10-3g/ml) induced relaxation by 97+/-5% (mean+/-SD). The extract was still effective but less potent tissue without endothelium or pretreated with L-NAME (10-4M). Similar effects were seen in aortic rings. CONCLUSION: Cocoa extract relaxes corpus cavernosal tissue in a dose-dependent manner via NOS and the endothelium. Cocoa extract may therefore be effective for improving erectile function.

PURPOSE: To identify sexual function improvement associated with alfuzosin (10 mg daily for 2 years). MATERIALS AND METHODS: We enrolled 30 men with lower urinary tract symptom (LUTS) who visited Gyeongsang National University Hospital between 2010 and 2012. At first visit, urinalysis, prostate specific antigen, transrectal ultrasound, and uroflowmetry were performed. The nternational Prostate Symptom Score (IPSS), quality of life (QoL), International Index of Erectile Function (IIEF), and Male Sexual Health Questionnaire Ejaculation Function Domain (MSHQ-EjFD) questionnaires were administered, and the subjects answered the same questionnaires at 1 month, 6 months, 1 year, and 2 years of follow-up. RESULTS: Twelve men completed of the entire study. After administration of alfuzosin, the median IPSS at first visit, 1 month, 6 months, 1 year, and 2 years was 18.00 (interquatile range [IQR]: 14.00~29.75), 20.00 (IQR: 11.50~30.00), 15.50 (IQR: 8.50~25.25), 14.50 (IQR: 9.25~19.50), and 11.50 (IQR: 5.00~17.75), respectively, which showed an improvement. The median QoL at the same times was 4.50 (IQR: 4.00~5.00), 4.50 (IQR: 4.00~5.00), 3.00 (IQR: 2.00~4.00), 3.50 (IQR: 2.25~4.00), and 3.00 (IQR: 1.00~3.00), respectively, and also showed improvement. Likewise, the median IIEF was 36.50 (IQR: 24.50~46.75), 37.50 (IQR: 26.75~47.25), 45.50 (IQR: 35.00~59.75), 48.50 (IQR: 34.75~62.75), and 47.50 (IQR: 43.25~61.00), while the median MSHQ-EjFD was 19.00 (IQR: 12.0~24.75), 19.50 (IQR: 13.50~27.75), 23.00 (IQR: 19.25~32.25), 26.50 (IQR: 18.25~34.50), 27.00 (IQR: 21.50~32.50), respectively, with both showing improvement. CONCLUSIONS: After administration of alfuzosin (10 mg daily for 2 years), the IPSS, QoL, IIEF, and MSHQ-EjFD all improved significantly. This means long-term administration of 10 mg of alfuzosin daily would be effective not only for LUTS but also erectile function and ejaculation.
