ABSTRACT
AIM: To investigate the effectiveness of minimally invasive conjunctivorhinostomy for complete bicanalicular obstruction, and to evaluate the advantages, complications, and degree of satisfaction after this technique. ●METHODS: Twenty - two patients ( 22 eyes ) with complete bicanalicular obstruction were selected as the research subjects, all patients were treated by minimally invasive conjunctivorhinostomy. The post - operation follow- up lasted for 3 - 27mo. Medical records were reviewed for demographic data, surgical time, length of the tubes, duration of follow-up, patency of the tube, postoperative complications, whether satisfied or dissatisfied with this procedure. Meanwhile, the data was analyzed for evaluating the clinical efficacy of minimally invasive conjunctivorhinostomy. ●RESULTS: The overall operative success rate was 95%(21/22), and the overall patient satisfaction was 68% (15/22 ) . The post - operation complications included:granulation tissue proliferation of the lower end of the tube 2 cases (9%), middle turbinate blocked the opening of tube 3 cases ( 14%) , nasal mucosa covering the opening of tube 1 case ( 5%) , the tube was blocked by secreta 5 cases ( 23%) , foreign body sensation 10 cases (45%), dry eye 2 cases ( 9%), regurgitation of nasal secreta discharge 8 cases (36%). ●CONCLUSION: Minimally invasive conjunctivorhinostomy can treat the complete bicanalicular obstruction. This operation method is characterized by simplicity, high success rate, short operative time, less tissue trauma, less complications, without facial scarring, and it is worth clinical promotion.
ABSTRACT
A 33-year-old female suffered from bilateral mass in the medial area and epiphora for 20 years. The mass recurred after incomplete removal several times. Ocular examination showed that the puncta and papillae of the both lower and upper lids were completely missing. At operation, there was obstruction in the bony portion of the nasolacrimal duct. The mass was a distended lacrimal sac. The lacrimal sac and the mucosa of the nasolacrimal duct were compJetely excised in the right side. The excision of lacrimal sac and mucosa of the nasolacrimal duct and conjunctivo-rhinostomy using Jones tube were performed in the left side. Nine months after operation, the patient was happy with the results and there was no recurrence.
