“…The author was the leading surgeon and had just finished residency training at the time the surgeries were started, and the others were first-year to third-year residents who did their surgeries under supervision of the author. The functional success rate in this study was 74.7%, which was less than that reported by Dolman12 and by Razavi et al27 (89.1% and 96%, respectively). There are several factors contributing to why inexperienced surgeons could have a lower success rate than more experienced surgeons,28 including difficulty in manipulation of the instruments in the nasal cavity,8 although this technique is less difficult than using an endoscope.…”

BackgroundSurgical scarring on the face and disrupted anatomy in the medial canthal area following external dacryocystorhinostomy (DCR) can be avoided by an endonasal approach. This study examined the outcome of direct visualization endonasal DCR, performed by young surgeons and residents.MethodsA retrospective case series of 75 consecutive endonasal DCRs performed under direct visualization from July 2002 to July 2004 were reviewed. Surgery was performed by surgeons and residents who had received no special training in the procedure. Full success was defined as no symptoms of tearing after surgery and anatomical patency with fluorescein flow on nasal endoscopy or patency to lacrimal syringing. Partial success was defined as a tearing decrease compared with prior to surgery and with anatomical patency, and failure was defined as no significant improvement in persistent tearing. The average follow-up duration was 26.83 ± 16.26 (range 6–55) months.ResultsSeventy-five DCRs were performed on 63 patients (four male, 59 female) of mean age 49.44 ± 16.63 (range 21–85) years. The surgery was successful in 54/75 eyes (72%), 37/54 eyes (68.5%), and 30/42 eyes (71.4%) at 6, 12, and 24 months, respectively. Partial success was achieved in 13/75 (17.3%), 9/54 (16.7%), and 9/42 (21.4%), and the failure rates were 10.7%, 14.8%, and 7.1% at 6, 12, and 24 months, respectively. The overall functional success with this technique was 74.7% and the overall anatomical patency was 92.0%. There were no serious complications arising from the surgery; three minor complications were documented, ie, an incorrectly placed silicone tube in the lower canaliculus, tube prolapse, and postoperative bleeding which needed nasal packing and eventually a developed retention cyst in the nasal cavity.ConclusionEndonasal DCR under direct visualization is a simple technique with minimal complications and a low learning curve, without the necessity for expensive instruments.

“…1 -2 Wochen [1,6]. Die postoperative Restenoserate, die bei 15% liegt [7,8], wird durch das Fortbestehen der bakteriellen Entzündung begünstigt. Eine effektive Antibiose ist daher Bestandteil sowohl der konservativen Behandlung der frühkindlichen Dakryozystitis als auch der perioperativen Therapie.…”

“…Die konservative antibiotische Therapie ist sowohl Teil der primären Behandlung bei frühkindlicher kTWS als auch der perioperativen Therapie nach tränenwegschirurgischen Eingriffen [6,10,11]. In 15% kommt es nach operativer Eröffnung der Tränenwege zu einer Restenosierung der Tränenwege, was durch eine bakterielle Besiedlung begünstigt wird [7,8]. Der Nachweis pathologischer bakterieller Kulturen in 97 % der Abstriche stimmt mit den allgemeinen Literaturangaben überein [5].…”

Bacterial colonisation plays a crucial role in cLDO, showing a positive culture in 97 % with frequent co-colonisation of several bacterial strains (often in combination with at least one Gram-negative strain). The sampling of a microbiological probe of the lacrimal duct is recommended at least in therapy-refractory cases. Current bacteria in cLDO can be effectively treated with chloramphenicol, fusidic acid and ciprofloxacin. The commonly used antibiotics erythromycin and gentamicin are inappropriate as monotherapeutics.

“…Bei anhaltenden Beschwerden ist die Tränenwegssondierung mit der Bowman-Sonde mit Überdruckspülung [12] mit oder ohne anschließende bikanalikuläre Schlauchintubation zur Nase die Therapie der Wahl. Die in der Literatur angegebenen durchschnittlichen Erfolgsraten nach TWS mit S schwanken zwischen 60-90 % [7,13,14]. Der Zeitpunkt der Operation wird dabei bislang jedoch kontrovers diskutiert.…”

“…Eine kürzlich durchgeführte prospektive Studie zeigte andererseits keinerlei Abfall der Erfogsaussichten mit steigendem Alter[27,32,33]. In der Literatur wird eine generelle Restenosierungsrate von 10-40 % nach TWS mit S angegeben[7,13,14]. Die allgemeine Erfolgsquote nach TWS mit S lag in dieser Studie bei 89 %.…”
