What is the role of partial middle turbinectomy in endocanalicular laser-assisted endonasal dacryocystorhinostomy?

The Frequency of Concomitant Adjunctive Nasal Procedures in Powered Endoscopic Dacryocystorhinostomy

PURPOSE

To assess the frequency of concomitant adjunctive nasal procedures performed in powered endoscopic dacryocystorhinostomy (DCR).

METHODS

Retrospective review of 269 consecutive powered endoscopic DCR's performed in 202 patients over a period of 10 years from 2003 to 2013. Patient records were reviewed for demographic data, clinical profiles and surgical notes. Concomitant adjunctive procedures were studied with relation to number of patients, indications, types of procedures (septoplasty, middle turbinoplasty and functional endoscopic sinus surgery or FESS) and complications.

RESULTS

269 powered endoscopic DCR's were performed on 202 patients. The mean age at surgery was 58.4 years (range 20-91 years). Adjunctive nasal procedures were performed in 53.4% (108/202) of the patients. 47% (95/202) required a septoplasty. Among the 95 septoplasty patients, 85 required solo septoplasty and 10 had additional sinus procedure. Middle turbinoplasty was performed in 5.9% (12/202) and septal papilloma excision was performed in 0.49% (1/202). No additional morbidity was noticed with adjunctive procedures. Successful outcomes of DCR were achieved in 96.5% of patients.

CONCLUSION

Simultaneous adjunctive nasal procedures were commonly required with powered endoscopic DCR. Septoplasty and middle turbinoplasty when performed as needed, provides an additional access to lacrimal region and may facilitate successful outcomes.

Endoscopic dacryocystorhinostomy as treatment for lower lacrimal pathway obstructions in adults: Review article

Obstruction of the lacrimal pathway is manifested by epiphora, infection, and blurred vision as well as ocular and facial pain. Conservative treatments only achieve temporary relief of symptoms, thus surgery is the treatment of choice. Dacryocystorhinostomy (DCR) is recognized as the most suitable treatment for patients with obstructions of the lacrimal system at the level of the sac or in the nasolacrimal duct. The aim of this operation is to create a bypass between the lacrimal sac and the nasal cavity. During the past 2 decades, advances in rigid endoscopic equipment and other instruments have made it possible to obtain more information about the anatomic landmarks of the nasolacrimal system, which led to the development of less-invasive and safer endoscopic techniques. However, many parts of the treatment process related to endoscopic endonasal dacryocystorhinostomy (EN-DCR) still remain controversial. This article reviews the published literature about the technical issues associated with the success of EN-DCR, and clarifies the pros and cons of different pre- and postoperative procedures in adults with lower lacrimal pathway obstructions.

Analysis of age as a possible prognostic factor for transcanalicular multidiode laser dacryocystorhinostomy

Purpose. To assess the prognostic value of age on the outcome of transcanalicular multidiode laser dacryocystorhinostomy (TCL-DCR) in patients with acquired nasolacrimal duct obstruction (NLDO). Methods. The medical records of TCL-DCR performed between March 2009 and September 2013 were reviewed retrospectively. Inclusion criteria include over 20 years of age, similar mean follow-up period, and similar mean duration of stenting. The main outcome is surgical success. The effect of age on success rate is also evaluated. Results. The anatomical success was 52% in Group 1 (20-30 years), 56% in Group 2 (31-40 years), 64% in Group 3 (41-50 years), 76% in Group 4 (51-60 years), and 88% in Group 5 (over 60 years). The statistical difference among Group 1 and Group 5, in terms of surgical success rate, was found to be significant (P = 0.009). Additionally, the 20-30-year-old patients had a failure rate 6.76 times higher than that of the over-60-year-old patients (P = 0.009; 95% CI, 1.605-28.542). Conclusion. TCL-DCR is a surgical treatment option for NLDO for which a skin incision can be avoided. The success rate of TCL-DCR for younger population is lower when compared with elderly population.

Diode laser treatment of hypertrophic inferior turbinates and evaluation of the results with acoustic rhinometry

Inferior turbinate hypertrophy is the most common cause of chronic nasal obstruction. When conservative medical treatment options fail in patients with inferior turbinate hypertrophy, reduction of the inferior turbinate can be performed using surgical techniques. Laser-assisted turbinate surgery has the advantages of limited tissue trauma and reduced bleeding. We evaluated the effectiveness and outcomes of using a diode laser (λ = 980 nm) in turbinate reduction. Our study included 62 patients with symptoms of nasal obstruction due to hypertrophic inferior turbinates, who did not respond to medical treatment (≥ 1 year). Patients were treated with diode laser between January 2009 and December 2010 in our ENT (ear, nose, and throat) department. Subjective outcome of severity of nasal obstruction was assessed on a standard 10-cm visual analog scale (VAS). Acoustic rhinometry was used to measure nasal patency. The cross-sectional areas 1, 2, and 3 and the volumes between 2.5 and 5.5 cm were measured. VAS scores and acoustic rhinometry measurements were performed preoperatively and 1, 6, and 12 months after surgery. The mean follow-up was 13.1 ± 1 months. The mean operation time was 3 min per turbinate; no nasal packing was necessary. We did not observe any major complications. Both subjective and objective evaluations showed significant improvement. VAS scores improved, the mean MCA2, MCA3, and V2-5 measurements increased significantly 1 year after surgery. In the first year after surgery, 53 of 62 (85.4%) patients reported marked improvements in nasal breathing. Our results showed that, objectively and subjectively, the success rates in diode laser-assisted turbinate reduction were satisfactory. The diode laser, being one of the most portable and least expensive of the lasers available for turbinate surgery, makes it possible for turbinate reduction to be performed under topical anesthesia within a short period of time with excellent patient acceptance.
