Different modifications of the surgical procedure have been developed over the years.<\/jats:p><jats:p>\n               Methods Patients with CDC due to postsaccal lacrimal stenosis and under treatment with DCR have been included in this retrospective study. Two groups of different surgical procedures were analysed: firstly DCR without reconstruction of the ductus nasolacrimalis (DNL, group 1) and secondly patients with reopening the DNL (group 2). Criteria for success were absence of permanent epiphora, absence of inflammation of the lacrimal sac (functional success), and no recurrent surgery with free patency of the lacrimal duct (anatomical success). This was obtained by questionnaire after a follow-up of at least 12 months. The impact of gender, ectasia of the lacrimal sac, dacryoliths, and prior lacrimal surgeries was analysed.<\/jats:p><jats:p>\n               Results Overall, 248 surgeries were enrolled in this trial. Mean age in group 1 was 68 years (range: 22 to 92 years) and gender ratio was 3.2 to 1 (female\u200a:\u200amale). In that group, 68 operations could be followed up. In group 2, 62 operations on patients of a mean age of 63 years (range: 24 to 89 years) and a gender ratio of 2.9 to 1 (female\u200a:\u200amale) were observed. Complete success occurred in 75.0% in group 1 and 75.8% in group 2. Recurrent operations were necessary in one case of group 2 (1.6%) and 4 cases of group 1 (5.9%). Gender (group 1 p\u2009=\u20091; group 2 p\u2009=\u20090.115; between groups p\u2009=\u20090.511), ectasia of the lacrimal sac (group 1 p\u2009=\u20090.877; group 2 p\u2009=\u20090.674; between groups p\u2009=\u20090.878), dacryolith (group 1 p\u2009=\u20091; group 2 p\u2009=\u20090.465; between groups p\u2009=\u20091), and prior lacrimal surgery (group 1 p\u2009=\u20090.092; group 2 p\u2009=\u20090.051; between groups p\u2009=\u20090.520) did not influence the success rates in each group or between groups. Significantly more dacryoliths were found during operations\n          of group 2 (p\u2009=\u20090.010).<\/jats:p><jats:p>\n               Conclusion Reconstruction of the DNL during DCR is a possible and easy modification, with a slightly better success rate in curing CDC. Intraoperatively, dacryoliths might not be apparent remain in the deeper parts of the lacrimal ducts. Therefore, these segments should be inspected during surgery.<\/jats:p>","DOI":"10.1055\/a-2158-5422","type":"journal-article","created":{"date-parts":[[2023,11,15]],"date-time":"2023-11-15T19:19:15Z","timestamp":1700075955000},"page":"30-38","source":"Crossref","is-referenced-by-count":2,"title":["Transcutaneous (External) Dacryocystorhinostomy with Reconstruction of the Ductus nasolacrimalis"],"prefix":"10.1055","volume":"241","author":[{"given":"Jens","family":"Heichel","sequence":"first","affiliation":[{"name":"Universit\u00e4tsklinik und Poliklinik f\u00fcr Augenheilkunde, Universit\u00e4tsklinikum Halle (Saale), Deutschland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wiebke","family":"Dettmer","sequence":"first","affiliation":[{"name":"Universit\u00e4tsklinik und Poliklinik f\u00fcr Augenheilkunde, Universit\u00e4tsklinikum Halle (Saale), Deutschland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Friedrich","family":"Paulsen","sequence":"additional","affiliation":[{"name":"Institut f\u00fcr Funktionelle und Klinische Anatomie, Friedrich-Alexander-Universit\u00e4t Erlangen-N\u00fcrnberg, Erlangen, Deutschland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6363-9202","authenticated-orcid":false,"given":"Mohammad Javed","family":"Ali","sequence":"additional","affiliation":[{"name":"Dacryology, LV Prasad Eye Institute, Hyderabad, Indien"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrea","family":"Schmidt-Pokrzywniak","sequence":"additional","affiliation":[{"name":"Institut f\u00fcr Medizinische Epidemiologie, Biometrie und Informatik, Martin-Luther-Universit\u00e4t Halle-Wittenberg, Halle (Saale), Deutschland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Arne","family":"Viestenz","sequence":"additional","affiliation":[{"name":"Universit\u00e4tsklinik und Poliklinik f\u00fcr Augenheilkunde, Universit\u00e4tsklinikum Halle (Saale), Deutschland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thomas","family":"Hammer","sequence":"additional","affiliation":[{"name":"Universit\u00e4tsklinik und Poliklinik f\u00fcr Augenheilkunde, Universit\u00e4tsklinikum Halle (Saale), Deutschland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hans-Gert","family":"Struck","sequence":"additional","affiliation":[{"name":"Universit\u00e4tsklinik und Poliklinik f\u00fcr Augenheilkunde, Universit\u00e4tsklinikum Halle (Saale), Deutschland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2023,11,15]]},"reference":[{"key":"ref1","first-page":"385","article-title":"Nuovo metodo conservatore di cura radicale (Dacriocistorinostomia)","volume":"10","author":"A Toti","year":"1904","journal-title":"Clin Mod Firenze"},{"key":"ref2","doi-asserted-by":"crossref","first-page":"1106","DOI":"10.1016\/S0161-6420(98)96015-8","article-title":"Prospective randomized comparison of external dacryocystorhinostomy and endonasal laser dacryocystorhinostomy","volume":"105","author":"J Hartikainen","year":"1998","journal-title":"Ophthalmology"},{"key":"ref3","first-page":"268","article-title":"Langzeitergebnisse der Dacryocystorhinostomia externa.
