In our study, there was no significant difference in the incidence between genders. The average age of the patients was 42.9 years. The incidence was highest in the fourth decade. There were no significant differences between the symptoms of odontogenic sinusitis and that of other types of sinusitis. However, almost all of the patients with odontogenic sinusitis had unilateral symptoms. Iatrogenic causes, which include dental implants and dental extractions, were the most common etiologic factor

Purpose: The aim of this study was to investigate how clinical features such as sex, age, etiologic factors, and presenting symptoms of odontogenic sinusitis are differentiated from other types of sinusitis. Also, this study was designed to find methods for reducing the incidence of odontogenic sinusitis. Materials and Methods: A retrospective chart analysis was completed on twenty-seven patients with odontogenic sinusitis. They were all treated at Kangbuk Samsung Hospital between February 2006

The described technique has a high success rate and can be performed under local anesthesia without external scarring. In the absence of donor site morbidity, this technique can also be utilized to repair posterior or multiple septal perforations without difficulty.

The maxillary sinus was the most common site of secondary mucoceles while the ethmoid sinus was the most common origin of primary mucoceles. Cases of secondary mucoceles that occurred following sinus endoscopic surgery developed more frequently in the ethmoid sinus than in those following the Caldwell-Luc procedure, therefore, we suggest that the incidence of maxillary sinus mucoceles in the Asian population would decrease as the rate of endoscopic sinus surgery increases.

OBJECTIVE: To evaluate the expression of cell-cycle regulators in papillary thyroid carcinoma in relation to lymph node metastatic features, and to determine whether immunohistochemical staining of cell-cycle markers can predict lymph node metastasis. STUDY DESIGN: Cross-sectional study of prior surgical specimens. SETTING: Academic tertiary referral center. SUBJECTS AND METHODS: We reviewed the clinical records of patients who had undergone surgery for thyroid cancer and follicular adenoma betw

Purpose: Numerous methods have been utilized to repair nasal septal perforation with varying degrees of success; however, no consensus has been reached on nasoseptal perforation repair. Here, the authors describe a surgical method based on human dermal allograft (SuredermTM, Hans Biomed Corp. Korea) for the repair of nasal septal perforations. Materials and Methods: Eleven patients with a nasal septal perforation were included in this study. The causes of these septal perforations included previ

BACKGROUND: The purpose of this study was to describe the posterior lacrimal sac approach in endoscopic dacryocystorhinostomy (DCR) performed at our institute and report perioperative results achieved with this procedure. METHODS: A prospective clinical study was performed of 35 adult patients with nasolacrimal duct obstruction who underwent posterior lacrimal sac approach DCR from March 1998 to May 2005. Follow-up period ranged from 13 to 30 months (average, 17.5 months; SD, 6.8 months). "Surgi

Transnasal endoscopic sinus surgery, followed by postoperative nasal cavity and paranasal sinus irrigation, is effective as a primary treatment method for paranasal sinus fungus ball.

Purpose: Paranasal sinus mucocele is a benign, expansile mass which can occur as a result of trauma or spontaneous obstruction of a sinus tract. The purpose of this study was to describe and compare the clinical characteristics of primary mucoceles occurring in patients with no previous sinus surgery history or known cause of mucoceles and secondary mucoceles resulting as a complication following endoscopic sinus surgery or the Caldwell-Luc operation. Materials and Methods: We performed a retros

Background and Objectives：Endoscopic intranasal dacryocystorhinostomy (DCR) has been used as a primary treatment of cause of DCR failure. Materials and Method：The endoscopic revision procedures were performed on 20 patients with re-curent epiphora after endoscopic DCR with anterior and posterior sac approach from 1995 to 2001. A retrospective review of 20 endoscopic revision procedures was done. Results：Sixteen patients (80% ) with recurent epiphora showed granulation on intranasal opening. Most
