The treatment of lacrimal apparatus obstruction with the use of an inner canthal Jones tube insertion via a transcaruncular route.

BACKGROUND AND OBJECTIVE: To evaluate the clinical utility of the lacrimal bypass surgery using Bowman's probe in treatment of obstruction of the lacrimal apparatus. PATIENTS AND METHODS: This study evaluated 124 cases of obstruction of the lacrimal passage systems with mean epiphora of 2.7 years. An incision was made on the side of the caruncle, and the lacrimal bone was penetrated between the lacrimal sac and the nasal mucosa by Bowman #0. Insertion of a Jones tube was made at the new lacrimal pathway, a puctum dilator or scissors was introduced through the caruncle and dilated across the lacrimal bone into the nasal cavity. The Jones tube was introduced over the probe into the nasal cavity, and fixed at the caruncle with nonabsorbable suture material. RESULTS: Complete resolution of epiphora was accomplished in 120 (96.8%) of 124 eyes; only 4 (3.2%) eyes failed during a mean of 17.1 months of follow-up. CONCLUSION: This procedure is simple and safe with no facial scarring, short operation time, high success rate, and can be performed under local anesthesia. Therefore, the clinical utility of this procedure seems to be of value in treatment of complicated obstruction of the lacrimal apparatus.

Propionibacterium propionicum and infections of the lacrimal apparatus.

Analysis of the clinical details associated with 26 referred isolates of Propionibacterium propionicum revealed the marked propensity of this anaerobe to be involved with infections of the lacrimal apparatus; 18 (69%) of the 26 referred isolates were from cases of canaliculitis in which this organism was regarded as the significant pathogen. Further analysis of data showed a significant correlation with the sex of the patient. Of the 18 cases of canaliculitis, the sex of the patient was reported in 16; 14 (88%) of these 16 patients were females (P < .005). The age of 13 of the 18 patients with canaliculitis was known (mean, 61.6 years; range, < 1-80 years); it appears from these cases that P. propionicum lacrimal infections are more common in later life. None of the referred isolates were identified as Actinomyces species. Despite the fact that infection of the lacrimal apparatus is known as ocular actinomycosis, it appears that P. propionicum is more frequently associated with the condition than are true Actinomyces species.

Is the lacrimal apparatus injured following cosmetic rhinoplasty?

A study was undertaken to test the validity of the belief that lacrimal apparatus injury is common in patients who undergo a cosmetic rhinoplasty. Dacryocystography was done in 15 patients immediately following the lateral osteotomy, and there was no evidence of lacrimal sac injury or extravasation of the dye in any patient.

[Micro-endoscopy of the lacrimal apparatus combined with Erbium YAG laser: an anatomical study. New methods of imaging].

PURPOSE: To study the anatomic structure and the endoscopic aspect of the lacrimal drainage system and to evaluate the efficacy of the Erbium laser with microendoscope in lacrimal obstruction. METHODS: Twenty lacrimal ducts from ten fresh cadaver heads were used to lead a special rigid probe of 1.1. mm diameter (Endognost Schwind). This probe combined a flexible endoscopic probe of 500 mu, an Erbium laser fiber of 375 mu and an irrigation. The probe was introduced through the inferior canaliculus. Progressing in the lacrimal system, all the images were analysed. Then, we used the laser fiber to open the lacrimal sac mucosa and the lacrimal bone. RESULTS: The anatomo-endoscopic analysis was performed using endoscopic data. We appreciated essentially the walls of valves and sinuses that appeared only functional when increasing the irrigation flow. The laser could easily open the mucosa and the lacrimal bone but not the maxilla. DISCUSSION: The small size of the cannula allows to use the system for the diagnosis of lacrimal obstructions. The combined laser allows to treat at same time canalicular obstructions and lower obstructions. CONCLUSION: The endocanalicular study of the lacrimal drainage system can diagnose the type of obstruction and can treat it. A clinical study is requested to confirm these results.
