ObjectiveTo develop an easy surgical approach to facilitate clinical management.Study DesignA novel transnasal endoscopic 3-step surgical method for vidian neurectomy
was designed and tried in 91 cases with a mild-to-severe degree of allergic
and nonallergic rhinitis refractory to routine medical therapy.SettingEndoscopic vidian neurectomy requires accurate localization of the vidian
canal. However, it is not easy to localize during surgery because of its
deep location and the complex anatomy of the pterygopalatine fossa.Subjects and MethodsThis technique consists of 3 steps, including transnasal endoscopic
perforation of the anterior wall of the sphenoidal sinus as the first step
and removal of the anterior wall until the exposure of the vidian canal in
the junction between the anterior wall and the floor of the sphenoid sinus
as the second step. The last step is the accurate resection and
cauterization of the vidian nerve. In some cases in which the sphenoid sinus
developed well with a big lateral space, an extended procedure of posterior
ethmoidectomy was included to allow good exposure of the vidian canal.ResultsUsing this technique, successful endoscopic vidian neurectomy in this series
of patients was confirmed by both histology and Schirmer test, showing its
distinct advantages of easy localization of the vidian canal and less risk
of injury to the nerve and vessel bundles within the pterygopalatine
fossa.ConclusionTaken together, this novel 3-step procedure of endoscopic vidian neurectomy
plus an extended procedure guarantees good exposure of the vidian canal and
therefore accurate vidian neurectomy.
A 49-year-old man presented with 3 months of persistent fever, cough, shortness of breath, and chest tightness. He had no response to treatment with antibiotics. He had been treated with an empiric 2-week course of steroids approximately 2 months before presentation, with mild and transient improvement. He did not use tobacco and had not experienced any weight loss, hemoptysis, arthralgia, or myalgia, and was otherwise in good health. He denied contact with anyone with pulmonary TB or other respiratory illnesses.
