An enlarged inferior turbinate is a predisposing factor for difficult nasotracheal intubation. We describe a case of successful nasotracheal intubation by induced outfracture of the inferior turbinate during maxillofacial surgery, and discuss the importance of adequate airway evaluation and anesthetic management for successful nasal intubation.

Peripheral T-cell lymphoma, which characterized by progressive ulceration and necrosis of the upper aerodigestive tract or midline facial structures, is rare disease in the otolaryngologic field. We recently experienced a case, revealed histopathologically peripheral T-cell lymphoma, involving inferior turbinate without any evidence of involving other organs. In this paper, we report two cases of peripheral T-cell lymphoma who was treated chemotherapy and concurrent radiation therapy.

Background and Objectives: Endoscopic repair of cerebrospinal fluid (CSF) leak can avoid morbidity of open approaches and has shown a favorable success rate. Free mucosal graft is a good method, and multi-layered repair is more favorable. The inferior turbinate has been commonly utilized for the free mucosal graft, but we newly designed it as a bone-periosteal-mucosal composite graft for multilayered reconstruction. Subjects and Method: Four subjects with a skull base defect were treated with this method. The inferior turbinate was partially resected including the conchal bone and was trimmed according to defect size. Both bony parts and periosteum were preserved on the basolateral side of the mucosa as a composite graft. The graft was applied to the defect site using an overlay technique. Results: All cases were successfully repaired without any complications. Three of them had a defect size greater than 10-12 mm, and the graft stably repaired the CSF leakage. Conclusion: Endoscopic repair of CSF leakage using inferior turbinate composite graft is a simple and easy method and would be favorable for defect sizes greater than 10 mm.

코의 3 대 생리학적 기능은 공기조화, 불순물과 공해물질의 제거, 그리고 후각 기능이다. 비강 내공기유동장의 특성에 대한 이해는 코 호흡의 생리학적 병리학적 양상을 이해하는 데 있어서 필수적이다. 정상 및 비정상 비강 내 공기유동에 대한 경험을 토대로 3 개의 하비갑개 수술 후 모델을 제작하여 PIV 실험과 수치해석을 통하여 유동을 해석하였다: (1) 하비갑개의 앞 부분만 절제한 I1 모델 (1) 하비갑개의 아래 부분만 절제한 I2 모델 (1) 하비갑개의 거의 전 부분을 절제한 I3 모델. 정밀한 CT 데이터와 이비인후과 전문의와의 긴밀한 협동 연구로 인해 해부학적으로 정확한 물리적 및 수치 모델을 제작할 수 있었으며 수술 방법에 따른 유동장의 차이에 대해 분석하였다.

Three major physiological functions of nose can be described as air-conditioning, filtering and smelling. Detailed knowledge of airflow characteristics in nasal cavities is essential to understanding of the physiological and pathological aspects of nasal breathing. In our laboratory, a series of experimental investigations have been conducted on the airflows in normal and abnormal nasal cavity models by means of PIV under both constant and periodic flow conditions. In this work, more specifically experimental and numerical results on the surgically modified inferior turbinate model were presented. With the high resolution CT data and a careful treatment of the model surface under the ENT doctor's advice yielded quite sophisticated cavity models for the PIV experiment. Physiological nature of the airflow was discussed in terms of velocity distribution and vortical structure for constant inspirational flow. Since the inferior and middle turbinate are key determinants of nasal airflow, the turbinectomy obviously altered the main stream direction. This phenomenon may cause local changes in physiological function and the flow resistance.

The author has evaluated the panoramic image of the maxillary sinus according to the skull position. The lead foils were attached to the five walls of the maxillary sinus and the inferior turbinate individually. The skull was located in three positions; standard position, 20㎜ forward position and chin-down position. The obtained results were as follows: 1. In standard position, the medial wall was superimposed upon most of the panoramic antral image. The anterior wall and the posterolateral wall were superimposed upon the medial half and the lateral third respectively. 2. In forward position, the width of the panoramic antral image was diminished generally. The anterior wall was superimposed upon most of the panoramic antral image and the posterolateral wall appeared narrowly at the most lateral portion of the panoramic antral image. 3. In chin-down position, there was no significant difference in comparison to the standard position. 4. Inferior turbinate was not superimposed upon the panoramic antral image.

Malignant melanoma of the nasal cavity occurs rarely. Malignant melanoma, originated from the upper respiratory tract including nasal cavity, has clinical feature of local recurrence and easily metastasizes to regional or distant lymph nodes, lung, and liver. Malignant melanoma originated from nasal cavity frequently shows tumor cell invasion, ulceration, or infection. Owing to these characteristics, complete surgical excision of the malignant melanoma in nasal cavity is not easy. And also the prognosis of this tumor is not so good because of a high recurrence rate. Recently the authors have recently experienced a case of malignant melanoma originated from the inferior turbinate, which was treated with lateral rhinectomy, total maxillectomy. The defect developed after surgical extirpation was reconstructed with rotational forehead flap.

The human turbinate-derived mesenchymal stem cells (hTMSCs), which were DiI-labeled and transplanted into the subretinal space in degenerating mouse retina, were observed in retinal vertical sections processed for rhodopsin (a marker for rod photoreceptor) by confocal microscope with differential interference contrast (DIC) filters. The images clearly demonstrated that DiI-labeled hTMSCs have rhodopsin-immunoreactive appendages, indicating differentiation of transplanted hTMSC into rod photoreceptor. Conclusively, the finding suggests therapeutic potential of hTMSCs in retinal degeneration.

Authors experienced a case of intermediate grade mucoepidermoid carcinoma in 29-year-old female. The origin of this tumor might be mucus secreting cells of palatal mucous gland. The characteristic features were as follows: 1. In clinical examination, exopytic mass was observed in left hard palate and similar to pleomorphic adenoma. 2. In radiographic findings, destructive changes of left hard palate, nasal septum, nasal inferior turbinate and floor of maxillary sinus and soft tissue mass were observed. 3. Histopathologically, mucus-secreting cells, epidermoid cells and intermediate cells were observed and diagnosed as intermediate grade mucoepidermoid carcinoma.

Klippel-Feil syndrome is characterized by congenital fusion of two or more cervical vertebrae, a low hair line at the back of the head, restricted neck mobility, and other congenital anomalies. We report a 16-year-old young man with Klippel-Feil syndrome, Sprengel deformity of the right scapula, thoracic kyphoscoliosis, and mandibular prognathism with an anterior open bite. He was treated with orthodontic treatment and maxillofacial surgery. An anticipated difficult airway due to a short neck with restricted neck movements and extrinsic restrictive lung disease due to severe thoracic kyphoscoliosis increased his anesthesia risk. Due to his deviated nasal septum and contralateral inferior turbinate hypertrophy, we chose awake fiber optic orotracheal intubation followed by submental intubation. Considering the cervical vertebral fusion, he was carefully positioned during surgery to avoid potential spinal injury. He recovered well and his postoperative course was uneventful.
