鼻内視鏡下涙嚢鼻腔吻合術症例の検討 : 手術手技の工夫と成功率の比較 Clinical Study of Endoscopic Endonasal Dacryocystorhinostomy
Nasolacrimal duct obstruction is normally treated with extranasal dacryocystorhinostomy, but nasal endoscopic dacryocystorhinostomy has recently become more common due to the development of nasal endoscopy. The subjects of the study were 23 patients who underwent nasal endoscopic dacryocystorhinostomy between December 2001 and July 2005 at Kohka Public Hospital, and who were followed for 6 months or longer. The presence or absence of lacrimal canaliculus obstruction was examined in a lacrimal probe test before surgery, and lacrimal contrast XP and CT were performed. During surgery, a Nunchakutype silicon tube was indwelled usually. The silicon tube was removed 3 months after surgery, and the success of the surgery was evaluated based on the improvement of subjective symptoms. The success rate was 88%, but obstruction recurred in 3 patients. Nasal endoscopic dacryocystorhinostomy was repeated in all recurrent cases, and obstruction recurred again in 1 patient. Pus was retained in the lacrimal sac in the recurrent cases, suggesting the involvement of infection.
