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 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.

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.

Nasotracheal intubation is often the method of choice in oral or maxillofacial operations. During the insertion of endotracheal tube (ETT) through nostril, a considerable damage can be inflicted on the nasal mucosa by forcing ETT into the nasal cavity, and epistaxis may occur as a result of mucosal damage even when vasoconstrictors, a lubricated tube, and careful manipulation are employed. This study was conducted to observe whether balloon dilation technique(BDT) can help to minimize the expected problems during nasotracheal tube insertion and was to tried to get a data for further studies. In 30 patients in whom the nasotracheal tube was placed, smooth passage into the nasal cavity without using BDT occurred in 9 patients(30.0%). Of 21 patients(70.0%) who were come into the use of BDT when resistance to tube insertion due to anatomical structures of the nasal cavity was encountered, epistaxis was not developed. By the above results, The BDT appers to prevent epistaxis during nasotracheal tube insertion and to make an easy and smooth passage of the tube and then it suggest that the BDT should provide a basic data and an alternative to conventional techniques for a safe and atraumatic nasotracheal intubation.

PURPOSE: This study investigated the surgical results and nasal findings of an endoscopic dacryocystorhinostomy according to differences in nasal mucosal and lacrimal bone opening size. METHODS: This investigation included 40 eyes of 35 patients who had undergone endoscopic dacryocystorhinostomy by nasolacrimal duct obstruction between February 2003 and December 2004. Comparisons of nasal mucosal opening with lacrimal bone opening were performed using of digital images recorded during the operations. Opening size was defined as the definite to average length of the long and short axes of each opening. Success rates were evaluated by postoperative subjective symptoms and syringing findings. Postoperative nasal cavity findings were obtained by endonasal evaluation. The results were verified by the Pearson chi-square test. RESULTS: The success rate was higher in the group with a nasal mucosal opening size at least twice as wide as their lacrimal bone opening size (84.62%) compared to the group with a nasal mucosal opening sizes less than twice as wide as their lacrimal bone opening size (78.57%), but the difference was not significant (p=0.78). Granulation tissues were observed at a significantly lower rate in the group with nasal mucosal opening sizes at least twice as wide as their lacrimal bone opening size. CONCLUSIONS: Large resection of nasal mucosa in endoscopic dacryocystorhinostomy can improve the result by decreasing the granulation formation.
