미세절단기를 이용한 내시경 수술이 기존의 부비동 내시경 수술에 비해 출혈이 적고 수술 시간도 단축되는 장점들이 있어 선호되고 있지만, 안와나 뇌 등의 중요 구조물에 심각한 합병증들을 발생시키기도 한다. 저자들은 만성 부비동염으로 부비동 내시경 수술 중 미세절단기에 의해 지판과 내직근 손상으로 인해 심한 복시와 외측 편위가 있었던 50세 여자 환자를 경험하였기에 문헌 고찰과 함께 보고한다. 환자는 부비동 내시경 수술 중 미세절단기에 의해 좌측 내직근 손상으로 인해 안구운동 검사상 안검연의 중심부를 통과하지 못하는 심한 내전장애 소견을 보였으며 편위각은 40 프리즘디옵터의 외사시를 나타내었다. 전산화 단층촬영상 좌측의 안와 내측벽의 손상으로 안와 지방의 노출과 좌측 내직근이 손상된 소견을 볼 수 있었다. 안구의 심한 외측 편위와 지속적인 복시는 안과적 수술을 시행하여 교정하였다.

Pregnancy rhinitis is a relatively common condition. It is characterized by the presence of nasal symptoms, especially nasal congestion, not present prior to pregnancy, but typically present during the last 6 or more weeks of pregnancy, without other signs of respiratory tract infection or any known allergic causes, and disappearing completely within 2 weeks after delivery. Nasal saline irrigation, intranasal steroid spray, and oral antihistamines are usually recommended as the first line of treatment for rhinitis. However, most pregnant women refuse medical treatment for pregnancy rhinitis because of the fear of teratogenicity. Severe pregnancy rhinitis increases the risk of snoring, which has been suggested as having adverse effects on the fetus. In cases where the patients are unable to control their symptoms, pregnancy rhinitis can negatively affect the quality of life (QOL) as well as the pregnancy outcome. Therefore, special caution is required for determining the appropriate diagnosis and treatment modalities for pregnancy rhinitis. Here, we report for the first time, the successful treatment of pregnancy rhinitis that was unresponsive to conservative management and medical therapy by using microdebrider-assisted inferior turbinoplasty at the final stages of pregnancy, along with a review of the relevant literature.

Background: Laryngeal papillomatosis, which is cased by human papillomavirus, is the most common benign neoplasm of the larynx. However, the prognosis of this disease remains really unpredictable. The aim of this paper is to determine whether any clinical features at the time of diagnosis could predict its course. Material and Method: Eighty-six patients treated at our institution during the last 20 years were analyzed retrospectively. All patients had microsurgery under general anesthesia. All patients' follow-up period was more than 1 year. We divided the patients into 1) Juvenile versus adult group based on their age 20, 2) single surgical method with laser versus dual surgical method with laser and microdebrider group, and 3) single subsite versus multiple subsites group. And we compared the therapeutic outcome. Results: The recurrence rate was 100% (15 patients) in the JP group and 56% (40 patients) in the AP group. Juvenile versus adult group was the only independent prognostic factor by univariate, and multivariate analysis. Microdebrider resection technique and multiple subsites were not associated with treatment result. Time period from the first surgery to recurrence detection was different statistically only for the age group. The number of surgery in the JP group ranged from 1 to 31 (mean 8.8). In the AP group the number of surgery ranged from 1 to 25 (mean 3.7). It was statistically different. Conclusion: Prognosis for the laryngeal papillomatosis remains unpredictable. Only patients' age was the only independent prognostic factor.

Primary tumors of the parapharyngeal space are rare and account for only 0.5% of head and neck neoplasm. About 80% of parapharyngeal tumors are benign and 20% are malignant. Parapharyngeal space is classified into the Prestyloid space and the Poststyloid space. The Poststyloid tumors are usually benign lesions such as neurogenic tumors, paragangliomas, vascular tumors, or aneurisms. The origins of prestyloid tumors are much more diverse pathology, the pleomorphic adenoma in parotid deep lobe is most common type. Several surgical approaches have been introduced for management of parapharyngeal tumor, such as transcervical, transparotid-transcervical and the transcervical-transmandibular approaches. This paper is aimed to present a large parapharyngeal space tumor removed via transoral approach. It is possible to remove easier by using microdebrider. The pathologic diagnosis was pleomorphic adenoma.

Objectives : The aim of this study was to evaluate the effectiveness and feasibility of coblation resection for the treatment of laryngotracheal disease. Methods : We conducted a retrospective review, evaluating 7 patients with laryngotracheal disease treated using coblator. Information collected included demographic data of the patients, diagnosis, size and location of the disease, procedure time, the number of previous operation, and the postoperative complication. Results : Among the etiology, granulation is most frequent (n=4), followed by recurrent repiratory papillomatosis (n=2) and tracheal stenosis (n=1). The location of lesions was peristomal area (n=2), glottis (n=2), subglottis (n=2) and mid-trachea. Coblation resection could remove the lesions completely and there was no significant complication including local burn, bleeding, and hypertrophic scar. The procedure time was shorter than the previous operation using $CO_2$ laser. Conclusion : Coblation resection is an effective and safe method for layngotracheal disease and can substitute the classic method such as $CO_2$ laser.

Background and Objectives: Recurrent respiratory papillomatosis (RRP) is difficult to treat because of its tendency to recur and spread throughout the aerodigestive tract. We aimed to estimate the effect of intralesional injections of cidofovir in patients with RRP. Materials and Method: Within the period from January 2003 to July 2007, 13 patients aged 2 to 61 years were treated with intralesional injections of cidofovir combined with surgical excision of RRP. Cidofovir was injected intralesionaly at a concentration of 5 mg/cc after complete removal of the papilloma with $CO_2$ laser or microdebrider. We evaluated the effect of intralesional cidofovir therapy by comparing pre-treatment mean interval of recurrence with post-treatment interval of recurrence. Results: Of 13 patients, two patients showed complete response during follow up period and four patients showed partial response. Seven patients did not respond to cidofovir at all. Mean pre-treatment mean interval of recurrence was 9 months and mean post-treatment interval of recurrence was 13.1 months (p=0.039). There was a statistical significance between the injected dose of cidofovir and post-treatment interval of recurrence (p=0.009). There were no local or systemic side effects caused by cidofovir. Conculsion : Intralesional injection of cidofovir seems to have a potential of a safe and effective adjuvant therapy of RRP. There was a positive correlation between the injected dose of cidofovir and patient clinical outcomes so that administration of higher doses and more frequency of injections should be needed to reduce recurrence. Further study regarding injection therapy regimen for RRP is required.
