Anthropometric changes in the morphology of the lower eyelid after using three different approaches in patients with orbital fractures

PurposeThe aim of this prospective study was to address the anthropometric changes in the morphology of the lower eyelid and esthetic outcomes after performing subciliary, subtarsal, and transconjunctival approaches in patients with orbital and periorbital fractures.Patients and methodsA prospective randomized controlled clinical study was undertaken on patients with orbital floor and infraorbital rim fractures. These were equally divided into three groups: in group 1, the fractures were approached via a stepped subciliary approach; in group 2, they were approached via a subtarsal approach; in group 3, a retroseptal transconjunctival approach was performed. The patients were assessed for anthropometric changes in the morphology of the lower eyelid, esthetic outcomes, and postoperative lower eyelid complications (LLCs). A one-way ANOVA test was used to analyze differences between the operated and non-operated sides and the effect of the surgical approach on anthropometric measurements.ResultsA total of 45 patients were included in the study. All the surgical approaches provided adequate surgical exposure of the infraorbital rim and orbital floor. The subtarsal approach allowed rapid access to the field (10.5 ± 1.9 min). All incisions resulted in adequate postoperative esthetic outcomes. Anthropometric analysis revealed that there were no significant differences between the three approaches, except for measurements of the eye fissure index (EFI) and lower iris coverage (LIC). Mean EFI measurements increased on all operated sides. The subciliary approach showed the highest percentage of increased measurements of this variable (34.5 ± 4.6), followed by the subtarsal approach (32 ± 2.1), and then the transconjunctival approach (31.1 ± 3.7), with p = 0.046. Furthermore, the subciliary approach significantly decreased the measurements of LIC. This change was also bigger with the subciliary approach (1.09 ± 2.3) than with the subtarsal approach (2.1 ± 2.4) or transconjunctival approach (3.4 ± 2.6), with p = 0.048.ConclusionBased on the results of this study, the subtarsal approach is a minimally invasive incision that provides an adequate and direct approach to orbital floor and infraorbital rim fractures, with a favorable periorbital architecture and the lowest incidence of LLCs. Therefore, the subtarsal technique should be preferred over subciliary and transconjunctival approaches.

Retroseptal transconjunctival approach for fractures of the zygomaticomaxillary complex: a retrospective study

We designed a retrospective study to evaluate the efficacy of retroseptal transconjunctival approaches in the management of fractures of the zygomaticomaxillary complex (ZMC). The patients were from a single institution, and had had three-point fixation of fractures of the ZMC between 2008 and 2016. A total of 77 patients (56 men and 21 women with a mean (range) age of 28 (18–54) years), were divided into two groups. Group I (n = 51) had had reduction and fixation of the infraorbital rim using a retroseptal transconjunctival approach. In group II (n = 26) the same approach had been used with lateral canthotomy and inferior canthlolysis for both the infraorbital rim and the zygomaticofrontal region. We analysed the association of both approaches with the outcomes of reduction, fixation, and complications. Suboptimal results were found in 13 patients in group I and one in group II (p = 0.017). There were also three patients with trichiasis and two with entropion in group I, and one each of both complications in group II. There was only one patient with a malopposed lateral canthus in group II. All 26 patients in group II had no perceptible scar along the extended line of incision. The risk of a suboptimal outcome was reduced by 20% (relative risk = 0.8) in group II. The retroseptal transconjunctival approach with lateral canthotomy and inferior cantholysis is safe, aesthetic, and effective in the management of fractures of the ZMC.     

Use of the preseptal transconjunctival approach in orbit reconstruction surgery.

PURPOSE: This report evaluated the advantages of the preseptal transconjunctival approach in reconstruction of the orbit. PATIENTS AND METHODS: Ninety-nine preseptal incisions were used in 80 patients for different indications (blowout fracture, complex zygoma fracture, enophthalmos correction, midface hypoplasia, secondary incision). All operative procedures were performed without an additional lateral canthotomy. The infraorbital rim was stabilized with miniplates or microplates. RESULTS: There was no ectropion or entropion in any patients. Complications included 1 laceration of the tarsal plate and 1 temporary entropion after a primary subciliary incision. The overall complication rate was 2%. CONCLUSIONS: The preseptal transconjunctival incision without lateral canthotomy provides good exposure of the orbital floor and the caudal parts of the lateral and medial wall. This approach is preferable to a retroseptal approach in reconstructive orbital surgery because of minimal disturbance of the intraorbital connective tissue framework. The anatomic optimal dissection line also results in a lower complication rate.     

Comparison of ‘sutureless’ Transconjunctival and Subciliary Approach for Treatment of Infraorbital Rim Fractures: a Clinical Study

Purpose

The aim of the study is to compare subciliary incision and ‘sutureless’ transconjunctival incision in the treatment of infraorbital rim fractures.

Materials and method

In this prospective study, 40 patients with fractures of the infraorbital rim were selected and divided into 2 groups using random sampling technique. Group A patients were treated using ‘sutureless’ transconjunctival technique and group B patients were treated using subciliary approach. The following parameters were compared a) time taken, intraoperative ease of access, exposure achieved; b) clinical outcome and postoperative complications; c) Aesthetic outcome at intervals of 15 days, 1 month and 3 months.

Results

Total time taken for completion of surgery was lesser in group A patients. The presence of subconjunctival ecchymosis (at 1 month interval) and neurological deficit was found to be statistically significant (P<0.05) in the ‘subciliary’ group of patients. The transconjunctival approach showed better esthetic results and fewer post-operative complications.

Conclusion

The subciliary approach gives good exposure of the infra-orbital rim and is better suited to reduce extensively displaced fractures of the infra-orbital rim. The transconjunctival approach is comparatively faster, gives better esthetic results and fewer post-operative complications but is technique sensitive and requires an additional lateral canthotomy in cases where more exposure is needed.

     

The transconjunctival approach for treating orbital trauma

Twelve patients with a variety of maxillofacial injuries were treated with a transconjunctival incision and lateral canthotomy for orbital floor, and inferior and lateral rim reconstruction. Mean follow-up was 12 months, during which time no immediate or delayed complications developed. The exposure and access was satisfactory in all cases for reduction and rigid fixation of both inferior and lateral rim through a single incision.     

Comparison of preseptal and retroseptal transconjunctival approaches in patients with isolated fractures of the orbital floor

Transconjunctival approach has become a standard procedure to access fractures of orbit and the infraorbital rim. The transconjunctival incision can be performed pre- or retroseptally. Both approaches have been described combined with modifications such as transcaruncular or detachment of the lateral canthus for wider exposure of the orbital walls and rim.Particularly concerning aesthetics, the transconjunctival approach shows advantages compared to the transcutaneous incisions, such as the transciliary and infraorbital access. Moreover, transconjunctival approach is preferred in the literature regarding lid retraction. In this study the preseptal approach is compared with the retroseptal approach concerning en- or ectropion, foreign body sensation and formation of symblepharon. In our collective complication rates were lower in the retroseptal transconjunctival group, although this was not statistically significant. Whether the preseptal or the retroseptal transconjunctival approach is selected, is rather based on the surgeon's preferences. Nevertheless, the retroseptal approach must be considered as advantageous alternative to the preseptal approach because of simpler surgical technique and the safer distance to the vulnerable lid apparatus.     

Tarsal strip technique for correction of malposition of the lower eyelid after treatment of orbital trauma

Purpose

The transconjunctival, subciliary, subtarsal, and subpalpebral approaches for accessing the infraorbital rim and orbital floor have both advantages and disadvantages. The most common complications include rounding of the lateral canthal angle, lower eyelid retraction with inferior scleral show, and frank ectropion.

Materials and patients

From 2000 to 2007, we treated 29 patients with lower eyelid malposition after surgery to manage the floor and infraorbital trauma (22 subciliary approaches, five transconjunctival approaches and lateral canthotomies, and two transconjunctival approaches). To correct lower eyelid malposition, we applied the tarsal strip technique in all patients.

Results

Twenty-five patients had scleral show and four patients had ectropion: three were previous treated using transconjunctival access and one using subciliary access. Twenty-six patients obtained satisfactory correction of eyelid malposition in a single-step surgical procedure, while three patients required a second surgical step to correct the remaining scleral show. Good aesthetic and functional results were achieved in all cases.

Conclusions

All approaches to the infraorbital rim or orbital floor have the potential for postoperative sequelae. The tarsal strip technique is a relatively simple technique that oral and maxillofacial surgeons can use to manage lower lid malposition, such as scleral show and ectropion.     

A comparative study of different approaches in the treatment of orbital trauma: an experience based on 274 cases

Purpose

The aim of the study was to compare the aesthetic results, complications and surgical indications in patients treated for orbital trauma by one of three different approaches: subciliary, transconjunctival or transconjunctival with lateral canthotomy.

Materials and methods

In this retrospective study, 274 patients (169 men and 105 women aged 16–78 years) who had been treated for orbital trauma without soft tissue lacerations of orbital region and then returned for long-term follow-up (6–48 months) between 2000 and 2007 were evaluated in terms of aesthetics and function for the presence of a visible scar and lower-eyelid malposition (scleral show or ectropion).

Results

Of the 274 patients, 50 (18.2%) experienced complications. In the group of 219 patients treated with the subciliary approach, 41 experienced complications, whereas amongst the 32 patients treated with the transconjunctival approach, there was one complication (0.3%) and amongst the 23 patients treated with the transconjunctival approach and canthotomy, there were eight complications (34.8%).

Conclusions

Patients treated for orbital trauma with the transconjunctival approach with canthotomy had a higher rate of lower eyelid malposition. Transconjunctival incision without canthotomy was the most successful surgical approach for the treatment of isolated fracture of the orbital floor; however, when major surgical exposure is necessary, subciliary incision is recommended.     

Transconjunctival versus subciliary approach to the infraorbital margin for open reduction of zygomaticomaxillary complex fractures: a randomized feasibility study

Introduction

Although some studies addressed the differences between subciliary and transconjunctival approaches, no previous prospective comparative study on displaced zygomaticomaxillary complex (ZMC) fracture that repaired by three-point internal fixation using also upper gingivolabial incision and upper eye lid incision. So, the effect of these incisions on the comparison was not investigated.

Purpose

The purpose of this study was to compare transconjunctival and subciliary approaches for open reduction and internal rigid fixation (OR/IF) of ZMC fractures.

Methods

This prospective study was carried out on 40 patients had displaced ZMC fractures repaired by OR/IF. Patients were randomly assigned into two equal groups (20 patients for each); subciliary group subjected to subciliary approach and transconjunctival group subjected to transconjunctival approach for inferior orbital rim repair. In both groups, frontozygomatic and zygomaticomaxillary buttresses were also approached by lateral eye brow and superior gingivolabial incision, respectively. Primary outcome measures include accessibility (need for lateral canthotomy), the exposure duration, postoperative pain, early postoperative edema, and operative complications. Secondary outcome measures include dental occlusion, average intrinsic vertical mouth opening, post subciliary scar assessment, late postoperative complication, and opthalmological assessment concerning ectropion, entropion, scleral show, and eye globe affection (enophthalmos or diplopia).

Results

The mean duration from incisions to fracture exposure was 13.7 ± 2.17 min in subciliary approach and 14.6 ± 2.31 min in transconjunctival approach with nonsignificant difference (p = 0.1284). Lateral canthotomy was required for proper exposure of the fracture and OR/IF using transconjunctival approach while not needed with subciliary approach. Ectropion and scleral show occurred in 10 and 15% respectively in subciliary group and were not encountered in transconjunctival group. Although postoperative periorbital edema was significantly more sever in transconjunctival group within the first postoperative week (p = 0.028), no persistent periorbital edema was reported. Infection, hematoma, and globe complication were not detected in any patient. All authors characterized all scars of the subciliary group as unnoticeable.

Conclusion

Transconjunctival approach mostly needs lateral canthotomy that was not needed with subciliary approach. Transient postoperative edema is more in transconjunctival approach while postoperative ectropion and sclera show was detected only with subciliary approach. So, building up of experience in transconjunctival approach will be beneficial for maxillofacial surgeons and more measures to avoid ectropion are needed with subciliary approach.

     

Lateral canthotomy transconjunctival approach to the orbit.

Multiple surgical approaches to the orbits with the use of the eyelids have been used. The orbital rim incision fell into disfavor because of esthetic considerations. A subciliary approach supplemented by the lateral brow incision is currently the most popular method of approach to the orbital rim. It provides adequate access to the orbit, but it is not without inherent complications, such as unfavorable scarring, ectropion, and entropion. This article describes an alternate approach to the orbit by means of a transconjunctival incision with lateral canthotomy.     

Subciliary versus swinging eyelid approach to the orbital floor

In this retrospective study, the authors compare the outcomes of two different approaches to the orbital floor: the classic subciliary versus the transconjunctival plus lateral canthotomy (swinging eyelid). Forty-five patients who underwent orbital surgery (47 approaches) for different indications (orbital fractures, correction of Grave's exophthalmos, tumours of the internal orbit and correction of enophthalmos in secondary trauma) were placed in two groups, depending on the approach. The long-term effects of the incisions, the outcome of the approach and the complications were recorded and compared. The minimum follow-up for inclusion in the study was 1 year. Twenty-three orbits underwent subciliary incision, and 24 underwent swinging eyelid. No ectropion or entropion was seen in any patient. For the swinging eyelid approach, complications included three cases (12.5%) of canthal malposition; for the subciliary approach, five cases (21.14%) of lagophthalmos and 10 visible scars were observed. Our findings show the advantages of the swinging eyelid: better aesthetic results, the same or greater exposure of the orbital floor and the caudal part of the lateral and medial walls, shorter surgical time (sutureless) and a less extended scar. Although in our experience this approach is preferable in orbital surgery, some indications for the subciliary still remain.     

Versorgung von Jochbeinfrakturen über einen transkonjunktivalen Zugang mit lateraler Kanthotomie unter Schonung des lateralen Lidbandes

Introduction

This study reports on a modified approach to treat zygomatic fracture. For the surgical approach, a transconjunctival incision and, instead of a lateral canthotomy, a superficial incision of the skin and subcutaneous tissue was used, preserving the lateral ligament. The results are compared with those of previous techniques, especially the subciliary incision.

Patients

In a prospective study, 30 patients (9 females and 21 males, mean age 32.1 years) with zygomatic fractures were operated using this approach. Mean follow-up time was 6 months after removal of the plates. Fractures were caused by trauma due to fighting, bicycle falls, or sport accidents. Follow-up radiographs were used to evaluate the position of the zygoma after reduction and rigid fixation.

Results

Reduction and rigid fixation of the fractures were possible to perform in all cases. The access to the orbital floor and the exposure of the inferior and lateral rim were satisfactory and an additional latero-orbital cut was not necessary. The disadvantage of the complete incision of the lateral ligament with the necessity of intraoperative refixation and possible ectropium of the eyelid could be avoided. Injuries or infections of the cornea or the bulbus did not occur. Postoperative complications such as scar formation resulting in entropium or ectropium were not seen.

Conclusion

These results show that the transconjunctival approach with lateral superficial incision preserving the lateral ligament for treatment of zygomatic fractures is satisfactory in all cases of rigid fixation of both inferior and lateral rims. Because of its esthetic and functional advantages this approach has become standard in our department.

A study on coronal incision for treating zygomatic complex fractures

Objective  To study the value of coronal incisions for treating zygomatic complex fractures and evaluate the advantages, indications and complications associated with it. Method  In this prospective study, 12 patients were randomly selected regardless of age, sex requiring open reduction and internal fixation of communited zygomatic complex fractures with or without other associated fractures of the midface. Patients were all treated by coronal approach for open reduction and internal fixation of fracture of the zygomatic complex. Other local incisions were used if required. Results  In all cases postoperative complications were relatively minor except in one case were the temporal branch of facial nerve weakness persisted at 3 months. Whereas 5 cases reported with slight weakness of the temporal branch of the facial nerve which resolved at the end of 3 months. The time taken for exposure of the fracture site via the coronal incision had a mean of 28.7 minutes. There were no cases of flap infection and just 1 case of stitch abscess reported. The same case later reported with a hypertrophic scar formation of greater than 0.5cm at 3months. In all other cases scar formation was negligible and well hidden within the hairline. There were no reported cases of paraesthesia at the operated site or hollowing of the temporal fossa. Conclusion  The coronal incision provides excellent access to the zygomatic arch and zygomatic complex, aiding in good anatomical reduction and also has the added advantage of the scar hidden in the hairline. It also has disadvantages like long operating time, risk of facial nerve injury, scarring in patients with male pattern baldness, paraesthesia of operated site etc. Therefore the incision should be judiciously used and not overused and indications strictly applied.     

Reconstruction of medial orbital wall using a retrocaruncular approach

The purpose of the study was to analyze and describe the retrocaruncular approach to access medial orbital wall.A retrospective analysis was performed in patients referred for the treatment of orbital fractures between January 1st 2011 and July 31st 2017. The study included patients over 18 years old with isolated fractures of the medial orbital wall or combined with the orbital floor who underwent a transconjunctival approach with retrocaruncular extension and lateral canthotomy, and with a minimum follow-up of 6 months. Patients with fractures to the roof and/or lateral orbital wall were excluded.From a total of 319 orbits, 30 medial wall fractures were treated using a retrocaruncular approach, transconjunctival extension and lateral canthotomy. 7 of them were pure medial wall fractures and 23 were combined with orbital floor. Except for one case that required delayed reconstruction with customized orbital implant, all orbital reconstructions were successful in the first surgery. Only one patient developed a conjunctival granuloma in relation to the caruncle. No others patients had complications.This study concluded that this approach is a successful access for surgical treatment of medial orbital wall fractures because of their broad visibility without damaging structures, allowing adequate orbital reconstruction and excellent aesthetic results.     

A comparative evaluation of rhytidectomy versus retromandibular approach for Open Reduction and Internal Fixation (ORIF) of mandibular condylar fractures

Objective  This clinical study was carried out on thirty patients who underwent open reduction and internal fixation for condylar fractures via rhytidectomy/retromandibular approach were evaluated. Methods  Group I (rhytidectomy approach) were compared and evaluated clinically and radiologically with Group II (retromandibular approach) for the following parameters like surgical access, duration of surgery, anatomic reduction assessment with relevant radiographs, occlusal discrepancies, need for post operative IMF, facial nerve morbidity, other post operative complications and scarring. Results  There was a statistically significant difference between the two groups in the duration of surgery which was found to be significantly lesser for group II than group I. Access was better in group I. Scar was well camouflaged in patients of Group I when compared to group II. Conclusion  The rhytidectomy (Face-lift) incision which we have used in our study has all the advantages of the retromandibular approach with an added advantage of a less conspicuous scar and a wider exposure of the fracture site. The only disadvantage is the added time required for the closure which is not a concern as the aesthetic outcome of this technique is superior to the other approaches.     

Treatment of orbital floor blowout fractures with conchal auricular cartilage graft: A report on 14 cases

PURPOSE: We sought to present follow-up on 14 cases in which conchal cartilage graft was used to span small orbital floor defects (up to 2 x 2 cm). MATERIALS AND METHODS: Fourteen patients with orbital floor blowout fractures were included in the study; in 8 cases, there was associated fracture of the inferior orbital rim. The decision to proceed surgically was based on the presence of at least one of the following conditions: diplopia, enophthalmos, herniation of orbital tissues through gaps in the orbital floor bone, and concomitant displacement of bone fragments of the inferior orbital rim. Auricular cartilage was used in all cases. Access to the orbital floor was via subtarsal incision unless a laceration was present and useable. RESULTS: The incidence of clinical signs during follow-up and the surgical complications found (1 case of entropion, 1 case of palpebral edema) are fully comparable with those reported in the literature; they do not appear to be correlated to the use of a cartilage graft. CONCLUSIONS: The use of auricular cartilage has wide application for small orbital floor defects. The conchal graft is easy to harvest. It provides an optimal support function for the globe with minimum donor-site morbidity. A graft of adequate size ensures adequate stability.     

Minimally invasive endoscopic resection of benign tumours of the accessory parotid gland: an updated approach

The most common conventional approaches for the resection of benign tumours in the accessory parotid gland are a standard parotidectomy incision, a modified standard parotidectomy incision, or a face-lift incision. The resulting scars may severely affect the patient's postoperative appearance. The previously reported endoscopically assisted approach offers a less aesthetically invasive technique, but it may still leave a visible preauricular scar 4–5 cm long. We have used a modified endoscopic approach with minimal, and concealed, incisions for the resection of benign tumours in the accessory parotid gland. Five patients were diagnosed by physical examination, imaging, and preoperative fine-needle aspiration biopsy. They had endoscopically assisted resections using our modified approach, and we evaluated its feasibility. All the resections were successful. The mean operating time was 108 min (range 90–130). The postoperative scars were concealed and aesthetically satisfactory. There were no facial paralyses, salivary fistulas, or recurrences in the short term. Using endoscopically assisted resection we completely removed benign tumours from the accessory parotid gland and obtained good aesthetic results. Our updated endoscopic approach for these resections is successful with shorter, concealed incisions. It is a viable alternative to conventional approaches.     

Transconjunctival approach to the infraorbital region: a cadaveric and clinical study

The surgical anatomy of the transconjunctival approach to the infraorbital region was studied using fresh cadaver dissection, histological examination and in the clinical situation. The existence of a periorbital envelope which separates the orbital fat from the orbital septum, and a potential postseptal space was noted. Reference to these anatomical features could not be found in the literature. The postseptal space was used to gain access to the infraorbital rim and the orbital floor. Wire and plate osteosynthesis of the infraorbital rim and exploration and reconstruction of the orbital floor were performed without fat herniation into the operative field. Access was adequate for these procedures and lower lid malposition was not observed as a postoperative complication.
