Intraorbital surgery by transnasal endoscopic ethmoidal-lamina papyracea approach / 中国耳鼻咽喉头颈外科

ABSTRACT

OBJECTIVE To explore the feasibility of transnasal endoscopic surgery to treatment of intraorbital space occupying by ethmoidal-lamina papy-racea approach. METHODS The clinical data of 10 cases who underwent intraorbital surgery via transnasal endoscopic ethmoidal-lamina papyracea approach from June 2003 and Aug. 2006 were retrospectively studied. The patients included foreign body 1 case, cavernous hemangioma 2 case, lipoma 2 cases, inflammatory pseudotumor 2cases and hematoma 3cases. All intraorbital space occupying were operated by transnasal endoscopic ethmoidal-lamina papyracea approach but for one cavernous hemangioma which was dealt with through extra orbitectomy. The inflammatory pseudotumors were prescribed with glucocorticoid after operation.RESULTS Foreign body was removed successfully. One case of cavernous haemangioma was removed completely by transnasal endoscopic surgery and the other by extroorbital operation. All symptoms of proptosis and diplopia disappeared. One vision was enhanced from hand moving to 0.3 and another from light to hand moving. However, there was one hematoma which had been hindered about 14 days after damaged lost eyesight after operation. All cases were cured but one pseudotumor which recurred and was operated again. All cases were followed up 3 to 24 months. CONCLUSION Intraorbital surgery via transnasal endoscopic ethmoidal-lamina papyracea approach was available and feasible for the advantages of clear operation field, direct vision operation, less damage, rapid recovery and avoiding of facial scar, and intranasal endoscopic surgery can treat the rhino-orbital related diseases and nasal diseases at the same time.
