Nasal provocation test (NPT) is a procedure used to evaluate the hyper-responsiveness of nasal mucosa after exposure to a provocative allergen. We aimed to identify the clinical indication and contra-indication for the use of NPT, and to introduce the actual NPT laboratory protocol in our clinical practice. We also provide clinical information which could be useful in conducting NPT. Finally, we discuss the current limitations of NPT and present a plan to overcome these difficulties.

Nasal airway obstruction is one of the most frequent causes of revision rhinoplasty despite the golden rule that nasal function should not be sacrificed because of cosmetic reason. Nasal function is jeopardized due to diverse reasons including inaccurate diagnosis or inadequate surgical technique. Detailed and thorough evaluation of the nose with review of previous operative technique is necessary to find out exact causes of obstruction. Septum, middle vault, tip, nostril, and nasal mucosa are common anatomic areas of obstruction after rhinoplasty. They are often weakened, damaged, or even destroyed losing their original shape, strength, or position. Changes in these anatomic structures are strongly related to static and/or dynamic obstruction. In this article, authors reviewed the common locations, anatomic causes, and treatment strategies of nasal obstruction after rhinoplasty.

The authors evaluated the effect of topical mitomycin-C on the prevention of dacryocystorhinostomy internal ostium obstruction as antifibroblastic adjuvant. Topical 0.02% mitomycin-C(MMC) eyedrop was applied postoperatively to conjunctival sac of 75 patients who underwent endoscopic dacryocystorhinostomy-MMC group. MMC was instilled twice a day from postoperative 1 day for 7 days and from postoperative 4th week for 7 days. Properly matched another 75 patients without postoperative adjuvant MMC were compared with MMC goup regarding endoscopic findings, patency rates and other eyedrop complications. The internal ostium were patent in 85% in MMC group, and 77% in MMC and control group, respectively. Endoscopic examination of internal ostium showed mean final diameter of 3.4mm in MMC group and 2.5mm in control. There were no significant complications in MMC group except delayed epithelialization of nasal mucosa which had no relationship with surgical outcome.

The author, since 1969, has established and had experience with an ideal antral window operation as a simple type of intranasal surgery using a double flap mucous-plasty in the treatment of chronic maxillary sinusitis. This intranasal antrostomy with nasoantral window-plasty is an ideal technique in sinusitis cases with mildly infamed and reversible conditions, without polypoid and highly thickened mucosa of the maxillary antrum, and has provided satisfactory surgical results with the following advantages: 1. It prevents the postoperative occurrance of unpleasent complications such as cheek swelling, dental and labial numbness, obstruction of the nasolacrimal passage due to over-curettage, osteomyelitis and postoperative cheek cyst as in cases following radical surgery. 2. The technique of two mucosal flaps taken from the nasal cavity and the maxillary antrum covers the up-and down-margin of the window and can prevent postoperative bony bleeding and reclosing of the window due to over-granulation, and consequently can keep the nasoantral window permanently open for free drainage. 3. The operation is very simple and conveniently performed under local anesthesia and requires minimal hospitalization. 4. There is minimal reaction, and minimal injury to the mucosa which rapidly returns to normal function. 5. High antroscopic visibility, to determine the status of the antral interior at all times during the surgery and the postoperative treatment, is provided. 6. In consideration of excretory function, ventilation and directional ciliary beating of the antral mucosa, the author believes that this intranasal antrostomy with nasoantral window- plasty is ideal and a better procedure than other simple antrostomies and better than Boenninghaus's single flap-plasty in the choice of different plastic techniques of the mucosal flap, and also this operation can proceed to a radical antral procedure.

BACKGROUND AND OBJECTIVES: Although airflow sensation is believed to have a certain role in the subjective sensation of nasal patency, there are few studies that quantify and assess the sensation of nasal airflow. We designed an apparatus that delivers a pulsing jet of air to measure nasal airflow sensitivity. The aims of this study are to map out the airflow sensitivity of the nose, to evaluate the effect of decongestant on airflow sensitivity and to assess reproducibility. MATERIALS AND METHODS: The test sites were stimulated with a pulsing jet of air at gradually increasing velocities, and the minimum velocity at which the subject could detect the tactile sensation was recorded. The threshold velocities after phenylephrine spray were also measured and compared with the pre-decongestant values. The threshold velocities were obtained on two separate occasions to assess reproducibility. RESULTS: The nasal vestibule was more sensitive than the nasal mucosa to airflow, and the most sensitive area in the proper nasal cavity was the anterior end of the inferior turbinate. Sensitivity was not affected by decongestant spray. There was strong agreement between the first and second measurement values. CONCLUSION: Our method of measuring airflow sensitivity is believed to be useful in assesssing nasal airflow sensation.

Capsaicin, a nonenamide derived from Capsicum plants, has proven to be useful in patients with vasomotor rhintitis. In this study, we estimated the effects of 10-5 M capsaicin spray in patients with hypersensitive rhinitis. The drug was given 3 times per day for 3 days to each patient by means of a spray delivered to the nasal mucosa. Patient's symptom score was recorded by the same physician. We repeated this method after 1 week, 2 week, 4week, 8week, 12week, 16week and recorded their symptom score. As a result, the mean symptom score involving nasal obstruction, sneezing, rhinorrhea and itching was remarkably reduced by capsaicin spray. The present findings suggest that capsacine spray is a good therpheutic method for hypersensitive rhinitis patients.
