Airway Obstruction*

Patients with secondary cleft lip nose deformity usually complain not only aesthetic problems but also functional problems such as nasal obstruction. However, there have been few studies on nasal airway problem in secondary cleft lip nose deformity patients and no reports for the correlation between degree of the deformity and nasal airway obstruction. The authors selected 34 patients with secondary cleft lip nose deformity and measured the degree of morphological deformity by photo analysis and the degree of nasal airway obstruction by VAS score and acoustic rhinometry. Almost all patients complained of more obstructive symptom on the affected side. Functional anatomic structure and volume of the nasal airway examined by acoustic rhinometry showed that narrowest point was located above the nostril and pathological obstruction was more significant in patient group in both side and the area of the narrowest point and the total nasal volume was smaller in patient group. The result that alar contour difference has correlation with total nasal volume but not with objective symptom shows that there may be other factors affecting the nasal obstruction. Therefore the authors conclude that not only the correction of the external morphologic deformity but also the consideration of nasal airway obstruction is essential when performing operation on the secondary cleft lip nose deformity patients.

Objective: To report an unusual presentation of thyroglossal duct cyst causing airway obstruction in an elderly man. Methods: Design: Case Report Setting: Tertiary Government Training Hospital Patient: One Results: A 71-year-old man with an anterior neck mass was brought to the Emergency Room due to progressive difficulty of breathing. A smooth, non-ulcerating right supraglottic mass obstructed the airway. Following an emergency high tracheotomy, contrast computed tomography scan of the neck revealed a hypodense mass with peripheral rim enhancement in the right supraglottis and an extralaryngeal component. Intra-operatively, a dumbbell- shaped cystic mass with a tract connected to the hyoid bone led to a Sistrunk procedure. Final histopathology findings were consistent with thyroglossal duct cyst. Conclusion It is possible for an elderly patient with impending upper airway obstruction, dysphonia, and neck mass to still have a benign and congenital thyroglossal duct cyst with intralaryngeal extension.

PURPOSE: In most cases of nasal bone fracture, closed reduction with internal or external splint fixation approach is selected. However, because of indiscriminate insertion of the internal splint without considering of anatomical difference or deformity, insufficient fixation happens frequently that need additional fixation. Therefore, we suggest a new method for providing adequate support in reduced nasal bone by carving Merocel(R) that is fixed for the anatomical structure. METHODS: Closed reduction and internal fixation with carved Merocel(R) was performed in 15 nasal bone fracture patients from March, 2010 to July, 2010. Each patient was evaluated by physical examination, facial photographic check, simple X-ray, and computerized tomography. On the first day post-operation, location of packing and amount of reduction were checked by follow up X-ray and computerized tomography. In addition, patients' symptoms were evaluated. During the 3-month post-op follow up at out-patient clinic, operator, 2 doctors in training and one assistant performed the objective evaluations by physical examination on nasal dorsal hump, nasal deviation, nasal depression, nasal breath difficulty, and nasal airway obstruction. A survey of subjective patients' satisfaction in 4-stages was also performed. RESULTS: The results of follow-up computerized tomography of the 15 patients revealed that 11 patients had good reduced state. Three patients with combined maxillary frontal process fracture had over reductions. A survey performed on the first day post-operation showed that 14 of 15 patients answered that their current symptoms were more than tolerable. At the 3-month follow-up physical exam, one case had a dorsal hump. However, there were no nasal deviations, nasal depressions, nasal breath difficulties, or nasal airway obstructions. Twelve of the 15 patients answered more than moderate on the 3-month survey. CONCLUSION: Intranasal packing after carving the Merocel(R) considering anatomical structure is a new effective method to promote proper-reduction, maintain stability, and minimize patients' symptoms by addition of a simple procedure.

The congenital nasal piriform aperture stenosis (CNPAS) is a rare cause of neonatal airway obstruction and could be easily mistaken as the choanal stenosis or atresia. The piriform aperture is a term used to refer to the anterior nasal openings. The nasal airway obstruction in the neonate can result in respiratory difficulties and may be going to life threatening consequences. Computed tomography demonstrates in detail the underlying anatomic abnormalities which allows differentiation of the CNPAS from other upper airway abnormalities. We reported a case of CNPAS, a 1-month-old male infant presented with respiratory difficulties. Shortly after birth, he had mild respiratory difficulties and there was difficulty passing a nasal catheter intranasally. But he was improved through only conservative management and discharged at the age of 5 days. At the age of 1 month, CT scan revealed bilateral CNPAS.

The primary objective of this study was to determine whether adenoid hypertrophy and subsequent adenoidectomy affect pediatric nasal airway resistance and nasal geometry. The secondary objective was to evaluate the relationships between the degree of adenoid hypertrophy and nasal airway resistance or nasal geometry. Fifty-one children, aged 5 to 10 years, selected for adenoidectomy due to chronic nasal obstruction and mouth breathing were enrolled. The size of adenoid was evaluated by cephalometric radiograph. Nasal airway resistance and nasal geometry were evaluated by active anterior rhinomanometry and acoustic rhinometry respectively. These measurements were repeated 3 months after operation. The size of adenoid was found well correlated to preoperative nasal airway resistance but was not to preoperative nasal geometry. Nasal geometry was not changed after operation. However, nasal airway resistance was reduced significantly at 3 months after operation and the size of adenoid was found well correlated to postoperative changes of nasal airway resistances.
