ABSTRACT

PURPOSE: External dacryocystorhinostomy is routinely performed through a cutaneous vertical incision placed on the lateral aspect of the nose. The lower eyelid crease approach has been seldom reported. The purpose of this study is to report the cosmetic and functional results of the lid crease approach for external dacryocystorhinostomy in a series of patients.
METHODS: Prospective, interventional case series. Twenty-five consecutive patients (17 women) ranging in age from 3 to 85 years (mean ± SD= 44.84 ± 23.67) were included in the study. All patients but one underwent unilateral external dacryocystorhinostomy with a 10 to 15 mm horizontal incision placed on a subciliary relaxed eyelid tension line. The inner canthus was photographed with a Nikon D70S digital camera with a macrolens and resolution of 3008 x 2000 pixels at 1, 3 and 6 months after surgery. The resulting scar was judged from the photographs by 3 observers (ophthalmologist, plastic and head and neck surgeons) according to a four level scale (1= unapparent, 2= minimally visible, 3= moderately visible, 4= very visible).
RESULTS: The surgery was easily performed in all patients with a 90.48% success. Three of the elderly patients (ages 61, 79 and 85 yr) developed mild lacrimal punctum ectropion, which resolved with conservative treatment. One patient had a hypometric blink which spontaneously recovered within one month. The mean score for scar visibility was 2.19 (1st mo), 1.65 (3th mo) and 1.44 (6th mo).
CONCLUSIONS: The eyelid crease approach is an excellent option for external dacryocystorhinostomy. It leaves an unapparent scar since the first month after surgery, even in younger patients. The functional results are excellent and comparable to other techniques. Care should be taken in elderly patients with lower eyelid laxity in order to prevent lacrimal punctum ectropion.

RESUMO

OBJETIVOS: A dacriocistorrinostomia externa é classicamente realizada por meio de incisão cutânea nasal. Há poucos relatos sobre a incisão transpalpebral, posicionada no sulco infraciliar da pálpebra inferior. O presente estudo tem por objetivo relatar os aspectos cosméticos e funcionais utilizando a técnica transpalpebral.
MÉTODOS: Série de casos, intervencional e prospectivo. Foram incluídos 25 pacientes consecutivos (17 mulheres) com idades variando de 3 a 85 anos (média ± dp= 44,84 ± 23,67), que apresentavam dacriocistite crônica. A dacriocistorrinostomia foi unilateral em 24 casos e bilateral em 1 caso. A incisão transpalpebral foi posicionada no sulco infraciliar medial, com extensão de 10 a 15 mm. Foram realizadas fotografias digitais do canto interno (Nikon D70S, lente macro, resolução de 3008 x 2000 pixels) nos tempos pós-operatórios 1, 3 e 6 meses. A visibilidade da cicatriz foi avaliada por 3 observadores (oftalmologista, cirurgião plástico e cirurgião de cabeça e pescoço) utilizando a seguinte escala: 1= imperceptível, 2= minimamente visível, 3= moderadamente visível, 4= muito visível.
RESULTADOS: A DCR foi realizada sem dificuldades e com sucesso funcional em 90,48% dos casos. A pontuação média para visibilidade da cicatriz foi de 2,19 (1º mês), 1,65 (3º mês) e 1,44 (6º mês). Houve 3 casos de ectrópio leve do ponto lacrimal que foram tratados conservadoramente. Um paciente apresentou piscar espontâneo incompleto, com resolução no primeiro mês de pós-operatório.
CONCLUSÃO: A incisão transpalpebral é uma excelente via de acesso para realização da dacriocistorrinostomia. A cicatriz é pouco visível desde o primeiro mês após a cirurgia, mesmo em pacientes mais jovens. Os resultados funcionais são semelhantes ao das outras técnicas. Em pacientes mais idosos é necessário avaliação cuidadosa da frouxidão palpebral a fim de evitar a indução de ectrópio lacrimal.

INTRODUCTION

Since the twenties when Dupuy-Dutemps and Bourguet published their external dacryocystorhinostomy (DCR) technique the surgery has been performed, with slight variations, with the same type of vertical incision on the lateral aspect of the nose(1). Harris, in 1989, was the first to demonstrate that external DCR can also be done with a horizontal incision placed on a lower lid crease(2). In this study, we evaluated the cosmetic functional results of lower lid incision for external DCR.

 

METHODS

This prospective interventional case series included 25 consecutive patients (26 surgeries) with nasolacrimal duct obstruction. The sample consisted of 17 female and 8 male ranging in age from 3 to 85 years (mean ± SD= 44.84 ± 23.67). We did not include any patient with scars in the medial cantal area. One patient with a failed endonasal DCR and dilated lacrimal sac was included in the study. All patients underwent external DCR (1 bilateral) through the lower eyelid.

During the postoperative period the medial cantus of all patients was photographed at a 30-degree angle at 1, 3 and 6 months after surgery. A medical photographer using a digital Nikon D70S camera equipped with a macrolens and a built-in flash took all pictures. The resolution of the images was kept constant at 3008 x 2000 pixels. The images of each patient were shown to 3 observers (an ophthalmologist, a general plastic surgeon and a head and neck specialist) on a 22-inch computer monitor with a screen resolution of 1680 x 1050 pixels. The location of the incision was shown to the observers who were then instructed to grade the appearance of the scar using the following 4-level scale: 1- invisible, 2- minimally visible, 3- moderately visible, and 4- very visible.

The scores were averaged and one-way analysis of variance (ANOVA) was employed to compare the scores at the different times during the postoperative period.

 

SURGICAL TECHNIQUE

The incision was fashioned in a medial relaxed skin lower lid tension line. The total length of incision ranged from 10 to 15 mm (Figure 1). Local anesthesia with 2% lidocaine plus 1:100.000 epinephrine provided good homeostasis, which is important in order to avoid excessive cauterization. A myocutaneous dissection (Figure 2) was carried out inferomedially until complete exposure of the anterior lacrimal crest (Figure 3). The lacrimal sac and proximal nasolacrimal duct were exposed. The surgery then proceeded as usual. The skin was closed with 3 to 4 interrupted 6-0 nylon sutures. The muscle plane was not sutured.

 

 

 

 

 

 

RESULTS

Functional success, expressed by positive irrigation after 6 months of follow-up, occurred in 90.48% of cases. Three elderly patients (61 to 85 yr) developed mild lacrimal ectropion after surgery, which improved in all patients within a few weeks after conservative treatment with corticosteroid cream massage. One patient developed a hypometric blink without lagophthalmos or keratopathy, which spontaneously resolved within the first postoperative month.

The mean scores for scar appearance were: 2.19 at one month, 1.65 at 3 months and 1.44 at 6 months after surgery (Figure 4). ANOVA revealed significant differences in scar appearance between time points. (F=10.11, p=0.0001). Post-hoc Tukey tests revealed that the scores did not differ between 3 and 6 months but both differed from the one month score.

 

DISCUSSION

Our findings concur well with previous studies concerning the cosmetic aspect of the scar with lower eyelid incision for DCR(2,3). Lower lid relaxed skin tension lines are horizontal and incisions placed on these lines are hardly noticeable shortly after surgery. Although the classical nasal incision may also provide excellent cosmetic results(4,5), we believe that the lower eyelid approach has some advantages over the classical nasal incision. The dissection is in the lower eyelid minimizing the bleeding, there is no concern about angular vessels lesions, the lacrimal sac is approached from below at the nasolacrimal duct entrance and the osteotomy site is thus quite low preventing any degree of stump syndrome. There is no need to detach the medial canthal tendon, which is left undisturbed. Finally, as the nose is not manipulated the patients are able to wear glasses immediately after surgery.

We did not experience any technical problems during the surgery. As is the case for the classical approach, all surgeries were performed with just one surgical assistant. Contrary to Putterman's point of view, we do not think that there is any need for special equipment to safely perform the operation(6).

The few complications we have encountered were related to lower lid laxity. In elderly patients care should be taken during closure in order to avoid lacrimal ectropion. In our patients this complication was temporary and did not require any surgical correction.
