Medical ectropion repair. A new procedure

The lazy-T procedure described by Smith corrects medial ectropion of the lower lid by combining a horizontal full-thickness shortening of the lid with excision of conjunctiva and tarsus inferior to the punctum to invert the lid. However, some cases of senile medial ectropion involve an element of vertical traction on the skin as well as horizontal lid laxity. A new procedure is described that makes use of skin gained from horizontal lower lid shortening in the form of a medially based transposition flap to produce vertical skin lengthening. It is useful to treat medial ectropions that have horizontal laxity along with cicatricial components and has successfully relieved this condition in eight patients.     

Transcaruncular medial orbitotomy for stabilization of the posterior limb of the medial canthal tendon

Purpose : A method to stabilize the posterior limb of the medial canthal tendon (MCT), using a transcaruncular medial orbitotomy (TMO) approach, is described in a stepwise fashion. The technique described is a modified version of procedures published by Ritleng, Crawford and Collin, and Fante and Elner. Methods : A prospective clinical evaluation of MCT stabilization via the TMO approach was undertaken in 11 consecutive patients who presented with MCT laxity as one of the features of their ectropion. These cases are initially described in detail in two representative case reports, and summarized in 11 cases. The stepwise surgical approach is outlined. Results : All patients had improved symptomatology in terms of epiphora and comfort. Furthermore, in all cases the lid position was improved or normalized. In four of the 11 cases (36%) the lower punctum did not ultimately reside in the lacrimal lake, but the punctal position was nevertheless improved and the MCT was stabilized. Conclusion : The TMO procedure provides both excellent MCT stabilization and adequate placement of the lower lacrimal punctum onto the globe. It does not require canalicular resection, and avoids continued anterior displacement of the medial lower lid which may occur when only the anterior limb of the MCT is addressed surgically.     

Correction of involutional lower eyelid medial ectropion with transconjunctival approach retractor plication and lateral tarsal strip

AIM: We describe the technique and our results in managing lower eyelid involutional medial ectropion using a combination of lateral tarsal strip to address horizontal eyelid laxity, and transconjunctival inferior retractor plication to address inferior retractor dehiscence. METHODS: Patients with symptoms of epiphora or signs of medial ectropion were offered this procedure. All had the following characteristics: medial lower eyelid eversion, punctal eversion >3 mm, medial canthal tendon laxity <4 mm, significant horizontal eyelid laxity and lacrimal systems that were patent to syringing. RESULTS: A total of 24 eyelids of 17 patients underwent this procedure over a 12-month period. The mean age of the patients was 79.7 years; 11 were male and six were female. The mean follow-up time was 18 months. Two eyes had undergone previous surgery. All patients had restoration of the eyelid margin to the globe and relief of symptoms. No complications were noted. DISCUSSION: These results suggest that excision of posterior lamellar tissue is not necessary for correction of involutional medial ectropion. Transconjunctival plication or reattachment of retractors is easy to perform and allows for the repair of more than the medial portion of the retractors if required.     

Medial canthal tendon repair for moderate to severe tendon laxity

Background: Medial canthal tendon laxity is a common cause of epiphora and ocular irritation. It is difficult to treat due to the proximity of the lower canaliculus and punctum to the tendon. Methods: The results of a prospective series of patients with involutional medial canthal tendon laxity between 1997 and 2002 were reviewed. Symptoms and measured laxity were recorded before and after medial canthal tendon repair. The medial canthal tendon was routinely repaired through a cut along the lid margin extending from the punctum medially. This avoids a vertical cut onto the anterior lamella of the eyelid, which is useful if a skin graft is required. Results: Twenty lower eyelid medial canthal tendon repairs were performed on 17 patients. Preoperatively, the lower punctum in all patients was able to be distracted to the medial limbus or further and in 50% of cases, the lower lid punctum was able to be distracted to the pupil midline or further. Postoperatively all patients had reduction of their medial canthal tendon laxity. Postoperatively in 85% of cases the lower punctum was not able to be distracted beyond the medial limbus; however, 15% of cases still had significant residual laxity. Eighty‐five per cent of patients reported improvement in symptoms. Conclusions: This is an effective procedure in the majority of patients with moderate to severe medial canthal tendon laxity; however, residual lower lid laxity persisted in some patients.     

Eyelid retractor surgery as an adjunct to cicatricial ectropion repair

Purpose : To evaluate the effectiveness of eyelid retractor repair in cicatricial ectropion of the lower eyelid. Methods : The study design was a prospective case series. One hundred and twenty eight eyelids were operated on in 100 consecutive patients with cicatricial ectropion. All patients underwent lower eyelid retractor repair via a conjunctival approach combined with skin replacement to the anterior lamella with or without a horizontal lid tightening procedure. When only medial ectropion was present, a medial‐based transpositional skin flap was used to repair the anterior lamella (26 eyelids). The remaining eyelids with ectropion involving all or most of the eyelid underwent upper‐to‐lower eyelid lateral‐based transpositional skin flap repair (92 eyelids), or full thickness free skin grafting (10 eyelids). Horizontal lid tightening was performed by lateral canthoplasty in 123 eyelids. Results : Relief of cicatricial ectropion symptoms was reported in 90% of patients overall. A normal punctum position was achieved in 70% of eyelids, overall, and was highest (88%) with a medial‐based transpositional skin flap. Conclusions : Eyelid retractor repair combined with skin replacement and horizontal lid shortening is an effective procedure for cicatricial ectropion.     

Comprehensive, combined anterior and transcaruncular orbital approach to medial canthal ligament plication

PURPOSE: To assess the efficacy of a comprehensive technique for correction of severe punctal and medial lower eyelid ectropion and lower eyelid retraction associated with medial canthal ligament (MCL) laxity. METHODS: A comprehensive technique that plicates the anterior and posterior crura of the MCL was performed on 8 eyelids of 6 patients with punctal ectropion and MCL laxity. Preoperative and postoperative symptoms, punctal ectropion, medial lower eyelid ectropion, lower eyelid retraction, lagophthalmos, and exposure keratopathy were evaluated. RESULTS: At an average of 13 months (range, 8-17 months), preoperative symptoms of epiphora and discomfort improved or resolved in all eyes. Punctal ectropion improved in all eyes and completely resolved in 75% of eyes. Medial lower eyelid ectropion was corrected in all eyes, when present. Lower eyelid retraction, lagophthalmos, and exposure keratopathy improved in all eyes. In 1 case, edema of the caruncle and semilunar fold persisted for 6 months. CONCLUSIONS: Combined anterior and transcaruncular MCL plication is an effective and safe procedure for addressing severe punctal and medial lower eyelid ectropion that accompanies MCL laxity and is difficult to correct by other methods. This procedure provides stable, 3-dimensional support to the medial lower eyelid and punctum.     

Evaluation of the medial canthus blepharoplasty using the lazy-T method

PURPOSE: To evaluate the efficacy of surgical "Lazy-T" method used to correct ectropion of the lower punctum with the inferior lid laxity and the medial canthal tendon. METHOD AND MATERIAL: Between January 2004 and February 2005, four patients of mean age 67 years (+/-12) were operated with this method. In two patients, one eyelid was operated; the other two patients underwent bilateral lid surgery. Preoperative qualifications included: subjective assessment of epiphora (range 0-10 points), where 0 represents loss of epiphora and 10 points maximum intensification with ectropion of the lower punctum, laxity of the inferior eyelid more than 10 mm, and laxity of the medial canthal tendon of 2-nd degree or more. Two subjects, who expressed their consent, underwent lacrimal scintigraphy. Surgical technique included excise of the middle part of the lid at its full thickness, laterally from lower punctum, and correction of the conjunctiva. The follow-up period was 6 months on average. RESULTS: All patients reported reduction of epiphora of 5 points on the average. Eyelid laxity decreased by mean 4.5 mm (+/- 1.0 mm). In two patients epiphora regressed, in two others - decreased. All patients evaluated the cosmetic result as satisfactory. CONCLUSIONS: The "Lazy-T" correction is an effective procedure, which restores the lower punctum into its normal anatomical position. It is a simple surgical technique that can free patients from epiphora.     

Evaluation and Treatment of the Patient with Ectropion

The evaluation of the factors that cause ectropion or may be present with it have not been described systematically. This paper discusses the significance of and examinations for horizontal tarsal laxity, medial canthal tendon laxity, punctal malposition, vertical inadequacy of the skin, orbicularis oculi paresis, and inferior lid retractor defects, and recommends surgical techniques for correcting each defect.     

Centurion Syndrome: Clinical Presentation and Surgical Outcome

ABSTRACT

Purpose: To describe the clinical signs and outcome of surgery in cases with Centurion syndrome and highlight the clinical presentation of this syndrome. Methods: A retrospective review of records of patients with Centurion syndrome who underwent surgery between January 2002 and July 2007. The position of the punctum, nasal bridge prominence, Hertel exophthalmometry and the presence of inferiorly directed sharp angulation of the medial canthus was noted. The patients underwent anterior canthal tendon release, punctoplasty or medial conjunctivoplasty or a combination of these. Results: Of the 13 cases, 10 had been treated medically elsewhere. The mean age of onset was 20.7 years. Most of the patients were male 10 (76.9%). A prominent nasal bridge was demonstrable in 9 (69.2%) patients and sharp inferior angulation of the medial canthus, the ‘beak’ sign was present in 9 (69.2%) cases. Anterior canthal tendon release alone was performed in 4 patients, in combination with punctoplasty in 5 and with conjunctivoplasty in 4. Watering resolved in 10 patients. 3 patients who had a combination of anterior canthal tendon release and punctoplasty had persistent but asymptomatic epiphora. Discussion: Centurion syndrome is characterised by the abnormal anterior insertion of the medial canthal tendon with displacement of the punctum out of the lacrimal lake. Most cases present with unexplained watering. Surgical management by anterior canthal tendon release with or without conjunctivoplasty or lower lid retractor plication is usually successful.     

Entropion and ectropion repair: a snapshot of surgical practice in the United Kingdom

We aim to provide a snapshot of the current surgical practice for correction of entropion and ectropion, the two most common oculoplastic procedures carried out in the UK, by surveying 135 consultant oculoplastic surgeons via the tool Survey Monkey. Forty-seven (35%) consultants responded. For entropion, 44% of surgeons opted for lateral tarsal strip (LTS) + everting sutures (ES). Other first-line choices included LTS + transcutaneous retractor plication (21%), Quickert’s procedure (14%), ES (7%), and Wies procedure (5%). Important patient-related factors to consider were horizontal lid laxity and retractor dehiscence.

Regarding ectropion, LTS was most commonly practiced (35%), followed by LTS + transconjunctival retractor plication (28%), wedge excision (16%), and lateral canthoplasty (5%). The patient-related factors guiding choice were horizontal lid laxity, lateral canthal tendon laxity, and punctal position under traction. Responses found a wide range of preferred surgical techniques in practice. The factors guiding surgical choice were personal audit results (92% stated important/very important), familiarity with the technique (92%), and the technique being favoured by previous trainers (76%), suggesting current practice led by expert opinion, possibly due to a lack of evidence-based literature. This highlights the variety of core oculoplastic surgical techniques practiced and underlines the need for robust trials to guide surgical choice.     

Medial palpebral tendon repair for medial ectropion of the lower eyelid

The primary functional support for the medial eyelid is from the deep attachments of the orbicularis muscle to the posterior lacrimal crest and lacrimal diaphragm. A dehiscence of the deep medial canthal attachments can alter the position of the lower eyelid with subsequent tearing, medial ectropion, and ocular exposure. In this study, medial palpebral tendon reconstruction was performed on seven lower eyelids with medial instability or ectropion and a dehiscence of the medial palpebral tendon. A periosteal flap left attached to the posterior lacrimal crest was used to replace the attenuated or absent medial palpebral tendon. After a mean follow-up of 7 months, 86% (6/7) of the eyelids had acceptable cosmetic and functional results. The use of a periosteal flap to replace a dehiscence of the medial palpebral tendon has several advantages. The periosteal flap is readily available, strong, and autogenous. The lower eyelid and punctum are pulled tightly against the globe. Lastly, the procedure may be repeated or combined with other ectropion procedures.     

Lower eyelid medial canthal tendon laxity grading: an interobserver study of normal subjects

OBJECTIVE: To describe a simple grading system for medial canthal tendon (MCT) laxity and measure its reproducibility. STUDY DESIGN: Observational case series and interobserver variability study. PARTICIPANTS: Fifty subjects (100 lower eyelids) without eyelid disease. The age range was 19 to 98 years. METHODS: Subjects without eyelid pathology or previous surgery were selected. Two ophthalmologists assessed the position of the inferior punctum in relation to the cornea with the patient in primary gaze. Two measurements were made, the first with the lower eyelid at rest and then with the lateral distraction test. Both observers were masked to the other observer's measurements. MAIN OUTCOME MEASURES: Kappa statistics to show the strength of agreement between the two observers for the resting and lateral distraction eyelid positions. RESULTS: High kappa values were found for resting position (agreement in 92 of 100 eyelids) and for lateral distraction testing (agreement in 85 of 100 eyelids). The range of resting positions was from position -1 to position 1. The range of laterally distracted positions was from position 0 to position 5. Overall, a very high level of agreement was achieved between observers. CONCLUSIONS: This grading system for MCT laxity is simple, easy to learn and reproducible, easier than measuring in millimeters, and has an advantage over merely saying the tendon is "lax" or "not lax." We propose this standardized grading system in the evaluation of patients with entropion and ectropion to identify those patients who may benefit from MCT stabilization/plication.     

Laser conjunctivoplasty: a new technique for correction of mild medial ectropion

Thirty patients with mild medial ectropion of the lower lid were treated by Argon green laser. A diamond-shaped area (6 x 4 mm in size) on the medial part of the tarsal conjunctiva of the lower lid was burnt with overlapping spots until white blanching and visible contraction of tissue were seen. The apex of the diamond was kept 4 mm below the punctal opening. After an average follow-up of 6 months, functional success was achieved in 22/30 eyes. Anatomical success in terms of repositioning of the punctum was attained in 24/30 eyes. The only side effect noted was a mild burning sensation of the eyes lasting for two hours after the procedure. This is the authors' initial experience with a somewhat new and easy procedure to treat mild medial ectropion of the lower lid that can be performed on an outpatient basis.

Transcaruncular approach to medial canthal tendon plication for lower eyelid laxity

PURPOSE: A new operation to correct lower eyelid laxity was evaluated. METHODS: A new transcaruncular, orbital approach to posterior medial canthal tendon plication was performed on eight orbits of four cadavers, which were then analyzed with computed tomography or histologic techniques. The procedure was also performed on 23 eyelids of 15 patients with lower eyelid medial canthal tendon laxity, alone or in conjunction with other procedures. These patients were followed up for a mean of 12 months. RESULTS: Improved postoperative eyelid position, epiphora, and superficial punctate keratopathy were found. Radiographic and histologic analysis demonstrated consistency of suture placement without involvement of contiguous anatomical structures. CONCLUSIONS: This procedure appears to be a safe, reproducible, and effective corrective procedure for medial canthal tendon laxity and lagophthalmos. When combined with lateral lower eyelid tightening, it is also an effective treatment for lower eyelid retraction and superficial punctate keratopathy. Other potential advantages and complications of this procedure are described in comparison to other reported surgical methods used to address medial canthal tendon laxity and malpositions of the medial lower eyelid.     

Modified retractor plication technique in lower lid entropion repair: a 4-year follow-up study

BACKGROUND: Lower eyelid entropion is an eyelid malposition characterized by inward rotation of the eyelid margin associated with potentially significant discomfort and, occasionally, keratopathy. In this study we evaluated and compared the efficacy of two surgical techniques of retractor plication for involutional lower lid entropion repair. METHODS: Sixty-two consecutive patients (62 eyes) with involutional lower lid entropion were included. Of the 62, 34 underwent the Jones retractor plication technique, and 28 underwent a modification of this technique that simplifies the procedure. We evaluated horizontal lid laxity, medial canthal tendon laxity and lower lid excursion before and after surgery, and determined the rate of entropion recurrence in the two groups. All measures were obtained before and 1 month, 6 months, 1 year, 2 years, 3 years and 4 years after surgery. RESULTS: Preoperatively, there was no statistically significant difference between the two groups in any of the measures studied. Postoperatively, the mean amount of horizontal lid laxity was significantly less in the modified technique group than in the Jones technique group (6.86 mm [standard deviation (SD) 0.41 mm] vs. 7.30 mm [SD 0.64 mm]) (p < 0.05). Similarly, the mean amount of medial canthal tendon laxity in the resting position was significantly less in the modified technique group than in the Jones technique group (1.90 mm [SD 0.56 mm] vs. 1.25 mm [SD 0.43 mm]) (p < 0.05). The rate of entropion recurrence was significantly lower in the modified technique group (7.1%) than in the Jones technique group (14.7%) (p < 0.05). INTERPRETATION: The modified retractor plication technique showed encouraging results in terms of successful and long-lasting lower lid entropion repair.     

Anatomical basis of "senile" ectropion

A study of 20 patients with bilateral ectropion was undertaken to determine the exact anatomical etiology of the horizontal eyelid laxity which leads to "senile" (involutional) ectropion. Two previous studies on normal people have shown a slight increase in the horizontal length of the lateral canthus with increased age. The results of the 20 patients with ectropion revealed that the lateral canthal tendon is significantly increased in horizontal length as compared with normal, age-matched controls. Therefore, surgery directed to the repair of the attenuated, horizontally lax, lateral canthus is more appropriate than full-thickness block or tarsal resection of the normal eyelid in the palpebral fissue. Additionally, since normal full-thickness eyelid tissue is not resected, the horizontal length of the palpebral fissue will not be shortened. This results in a more pleasing cosmetic appearance as well as an improved functional result.     

Ultrasonic visualization of the effect of blinking on the lacrimal pump mechanism

Background The role of the lacrimal sac (LS) and the medial canthal tendon in the lacrimal pump mechanism is controversial. This study used ultrasonic visualization to analyze this phenomenon.Methods Movements of the LS and the medial canthal tendon during blinking were visualized with sonography. In addition, the maximal profile area of the LS was measured before and after blinking using 15-MHz sonography in 14 individuals with a normal lacrimal drainage system and in six patients with lacrimal duct obstruction.Results The upper part of the LS could be located as an echolucent structure between the lacrimal bone and the medial canthal tendon. The medial canthal tendon appeared to compress the LS during lid closure and release the LS during lid opening. The measured profile area of the visible normal LS at the compression time decreased by 50%. The dilated LS of patients with obstruction could also be compressed by the orbital muscle on blinking, but the maximum area decrease was only 15.5%.Conclusion The findings imply that the lacrimal part of the orbicularis muscle contracts during blinking, with the medial canthal tendon compressing the LS in a cranial direction. Completion of lid closure then compresses both canaliculi and LS, forcing the intrasacral fluid through the drainage system. The expansion of the LS during the opening phase of the blink causes suction, and after opening of the punctal areas the canaliculi and LS vacuum breaks to reload with tear fluid. These findings demonstrate the importance of the orbicularis muscle and the medial canthal tendon for the lacrimal pump mechanism during blinking.
