Surgical Results of Endoscopic Dacryocystorhinostomy and Lacrimal Trephination in Distal or Common Canalicular Obstruction

OBJECTIVES: To evaluate the surgical outcomes of endoscopic dacryocystorhinostomy followed by canalicular trephination and silicone stenting in patients with distal or common canalicular obstructions. METHODS: The medical records of 29 patients (31 eyes) from January 2001 to December 2009 who underwent endoscopic dacryocystorhinostomy followed by canalicular trephination and silicone tube insertion for the treatment of distal or common canalicular obstructions were retrospectively reviewed. The level of obstruction was confirmed by intraoperative probing. The outcome of the surgery was categorized as a complete success, partial success, or failure according to the functional and anatomic patency. RESULTS: The average age of the patients was 52 years. The duration of silicone intubation ranged from 4 to 11 months with an average of 5.7+/-1.6 months. The follow-up period after stent removal ranged from 4 to 15 months with an average of 8.2+/-3.3 months. Complete success was achieved in 25 out of 31 eyes (80.6%), partial success in 4 out of 31 eyes (12.9%), and failure in 2 out of 31 eyes (6.5%). CONCLUSION: Endoscopic dacryocystorhinostomy followed by canalicular trephination and silicone stent intubation may be safe and considered as an initial treatment of patients with distal or common canalicular obstructions.

Effect of Bimodal Hearing in Speech Perception Under Noisy Environment According to Residual Hearing / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: In this study, we evaluated the effect of bimodal hearing in the speech perception test and the increasing level of bimodal hearing over cochlear implantation in speech perception score regarding residual hearing. SUBJECTS AND METHOD: Nineteen prelingually deaf patients, who had used bimodal hearing over a period of 8 months, were divided in two groups in accordance to their low frequency residual hearing. The children were tested in open-set speech perception under +10 SNR and +20 SNR. The scores of bimodal hearing and unilateral cochlear implantation were compared by the Wilcoxon signed-rank test. Also, the increased level of speech perception scores of bimodal hearing over cochlear implantation alone were calculated using the formula, [bimodal score (%)-unilateral cochlear implantation (%)], and was compared between groups. RESULTS: In pure tone audiometry under silent condition, the result of bimodal hearing was similar to unilateral cochlear implantation in magnitude in both groups. Under the noisy condition, both groups had better result in bimodal hearing in terms of speech perception. Also, the increased level was higher in bimodal hearing over unilateral cochlear implantation in the better residual hearing group. However, since the sample size was small enough, it is considered that there was no statistical significance. CONCLUSION: Cochlear implanted patients with residual hearing are expected to get better speech perception in noisy environment with bimodal hearing regardless of the level of residual hearing.

Endoscopic Repairment of Septal Perforation with Using a Unilateral Nasal Mucosal Flap

OBJECTIVES: Nasal septal perforation is an anatomic defect of the cartilaginous and bone tissues of the nasal septum. Many approaches and techniques to repair nasal septal perforations have been reported on. The purpose of this paper is to report on our surgical technique and the results of the treatment for nasal septal perforations. METHODS: From May 2001 to March 2008, 14 patients (12 males and 2 females; mean age: 41.3 yr) were enrolled. The mean perforation size was 15 mm, and all the perforations were located at the cartilaginous portion. Our surgical technique is based on an endoscope-assisted endonasal approach, with dissection of unilateral advanced mucosal flaps with using a temporalis fascia graft. The follow-up periods ranged from 3 to 23 months (mean follow-up period: 8 months). RESULTS: Using our surgical technique on 14 patients, 12 cases (85.7%) of septal perforation were closed without complication. The remaining two patients (14.3%) had incomplete closures (about 2-3 mm) without any significant symptoms related to the remaining perforation. CONCLUSION: Our technique is a viable procedure with a high success rate for achieving closure of nasal septal perforations. It has the advantages of shortening the operative time, no external incision and avoiding any other perforation during the operation. Therefore, we consider it to be a good alternative for repairing nasal septal perforations.

The Significance of Radiologic Positive Finding of Paranasal Sinus in Bone Marrow Transplant Patients

BACKGROUND: Bone marrow transplantation (BMT) is a beneficial and curative technique used in different hematologic conditions or malignant neoplastic diseases. However, bone marrow transplant patients are at a higher risk of developing infections and complications due to previous chemotherapy, radiotherapy, immunosuppression, antibiotics therapy, multiple viral infections, and GVHD (graft-versus-host disease). OBJECTIVES: The purpose of this study is to determine the prevalence and clinical data of rhinosinusitis among patients with BMT. We also investigated whether pre-BMT positive radiologic finding could predispose patients to the development of post-BMT rhinosinusitis or not. MATERIALS AND METHODS: We reviewed the records of 203 patients who had received BMT in Kyungpook National University's hospital from September 1998 to August 2006. RESULT: Sixteen patients (7.8%) had radiologic positive finding before BMT. Fifteen patients had no sinonasal symptoms and did not get any treatment. Only one patient had rhinosinusitis so that BMT was delayed and treated with antibiotics. Among these patients, one patient got newly developed rhinosinusitis after BMT. After BMT, sinusitis developed in ten patients (4.9%), including one patient who had invasive fungal sinusitis. Our study revealed a higher incidence of rhinosinusitis among allogenic BMT patients than among autologous BMT patients. The most common symptoms and signs were fever. Only one patient complained of typical sinonasal symptoms. CONCLUSION: Even though the prevalence of rhinosinusitis is low (4.9%) among post-BMT patients, maintenance of a high index of suspicion among these patients is necessary because sinonasal symptoms and signs are generally minimized after BMT. The study concluded that pre-BMT positive radiologic findings without sinonasal symptoms is unlikely to develop post-BMT rhinosinusitis.

Glomus Tumor of the Nasal Septum : A Case Report

Glomus tumor is a benign tumor, which is believed to represent hyperplasia or harmatomatous development of the glomus body. It is relatively rare in the head and neck region, especially in the nasal cavity. Up to now, only about twenty cases of glomus tumor in the nasal cavity have been reported. We report a case of glomus tumor originating from the anterior portion of nasal septum, which was treated by local excision.

Correlation Analysis between SF36 and Polysomnographic Measures in Patients with OSAS / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: Despite the trend in the medical field to understand the effect of diseases on the quality of life, such a study regarding sleep apnea has not been prevailing in Korea. This study analyzed the result of a Medical Outcome Study Short Form-36 (SF-36), which is widely used to evaluate the effect of sleep apnea on patient's medical condition. SUBJECTS AND METHOD: This study included 131 patients of over 18 years of age and who participated in the SF-36 survey and finished the polysomnography study. The relationship between parameters was conducted with Spearman, and the comparison with the independent variables was done by running a paired t-test. RESULTS: AHI was on average 30.9+/-23.5 and BMI was on average 26+/-3.9 kg/m. Except body pain, all values which derived from the statistics of eight categories of SF-36 from the patients was significantly lower than those of the healthy control. In the comparable analysis of polysomnography and SF-36, AHI, the total sleep time, and the sleep efficacy (%) had significant correlation, but correlation coefficient was low (r<3.0). CONCLUSION: It is recommended that the quality of life of OSAS patients should be evaluated beside PSG in order to find out the degree of seriousness of OSAS and result of treatment.
