Total upper eyelid reconstruction

Total upper eyelid reconstruction is required infrequently and is a challenge following trauma or the removal of eyelid for tumor. The vertical forehead flap can provide the external lamella with a mucous membrane graft lining its posterior surface. Two cases of total upper eyelid reconstruction using this method are presented and discussed. Received: 10 August 1998 / Accepted: 19 November 1998     

Periorbital reconstruction using variations of the upper eyelid flap.

Tissues that have characteristics identical or similar to periorbital soft tissue are preferred for reconstruction in the eye region. The upper eyelid is part of the periorbital area that provides an ideal reserve of tissue for this purpose, without producing a donor-site deformity. We used the upper eyelid flap with different pedicle designs in various parts of the periorbital region in 21 patients, and achieved favourable results. The flap was medially-based in five, superomedially-based in seven, laterally-based in eight, and superolaterally-based in one. The tissue defects were the result of the excision of tumours in 18 patients, and of injury in three. The defects were located in the upper eyelid in two, the lower eyelid in five, the medial canthus in eight, the lateral canthus in four, and in the neighbouring orbitonasal zones in two. Different sized flaps were used according to the dimensions of the defects, which ranged from about 1 to 8 cm2. The upper eyelid flap is versatile, and provides tissue of ideal colour and texture. The procedure can be done quickly in one stage with minimal morbidity.     

Experience in upper eyelid reconstruction with the Cutler-Beard technique

Reconstruction of full-thickness upper eyelid defects has to supply a movable lid with perfect corneal protection, good aesthetic quality, and acceptable sequelae at the donor site. The Cutler-Beard procedure, a full-thickness cutaneoconjunctival inferior eyelid advancement flap, is a reliable method for reconstruction of total or partial upper eyelid defects. Especially in older individuals, the skin of the donor site is loose and provides sufficient tissue to stretch. Color and texture of the donor matches the recipient site perfectly. Destabilization or ectropion of the donor site, the lower lid, and retraction or entropion of the recipient site, the upper lid, are the main complications. Therefore, a modification of the classic technique should be considered by implantation of an enforcing inlay in the reconstructed lid (eye bank sclera, fascia lata, ear cartilage), especially in reconstruction of extended defects of the upper lid.

Modified Tessier flap for reconstruction of the upper eyelid

We present a modification of the Tessier or orbitonasojugal flap for use in upper eyelid reconstruction. It is suitable for repairing full-thickness defects involving 60% or more of the lid margin and has the advantage of being a one-step procedure.

Island orbicularis oculis myocutaneous flap from the upper eyelid for lower eyelid reconstruction

An island myocutaneous flap of orbicularis oculis for reconstruction of central lower eyelid defects is presented. This flap is able to cover anterior lamellar defects extending up to 2/3 of the lower eyelid. It is also suitable for full thickness defects when the posterior lamellar involvement is less than 1/3 and can be closed primarily. In our hands this flap proved to be a good alternative to the classic reconstructive methods for the lower eyelid, since in one operation it offers the same skin quality, exactly fitting the defect, with a low complication rate. This reconstructive method for lower eyelid defects is safe, relatively simple and provides good functional and aesthetic results. Received: 21 August 1996 / Accepted: 15 June 1997     

Ear helix flap for reconstruction of total loss of the upper eyelid.

We present a patient with a recurrent carcinoma of the right upper eyelid who underwent resection of the subtotal upper eyelid resulting in a full-thickness defect. The eyelid was reconstructed with advanced conjunctival lining and an ascending helix chondrocutaneous flap from the right auricle. This flap was nourished with a reverse flow of the frontal branch of the superficial temporal vessels. A superficial temporal vein of the flap was anastomosed to the zygomaticofacial branch of the superficial temporal vein at the lateral canthal region to ensure adequate drainage. The flap survived without any congestion. An ascending helix flap is the best candidate for total loss of the upper eyelid.     

Full-thickness eyelid reconstruction with a single upper eyelid orbicularis oculi musculocutaneous flap

Eyelid tumors affecting the eye in general prove to be highly challenging to plastic surgeons. Reconstruction must be precisely detailed when dealing with lesions that primarily affect the skin but progressively the eyelid margin. Conjunctiva invasion damage is estimated to one-third or less in size when compared with the damage caused on the anterior wall of the eyelid. Although serial techniques for extent and location of full-thickness eyelid reconstruction have been detailed, the orbicularis oculi muscle can be easily raised as an island musculocutaneous flap. The eyelid's bilaminar wall is recreated by folding the flap on itself and full-thickness eyelid reconstruction is achieved sacrificing minimal accessory tissue. The small cutaneous section in contact with the globe becomes tolerable. As no single method for full-thickness eyelid reconstruction applies to extent and location to a wide range of defects, the proposed flap is safe, reliable, and beneficial to oculoplastic surgery.     

Influence of periosteum on donor healing after harvesting hard palate mucosa

The authors report the influence of periosteum on healing of palatal defect based on more than 10 years of experience of harvesting hard palate mucosa. Between June of 1991 and May of 2001, the authors harvested 80 hard palate mucosae as graft material for skin and mucosa defects. All grafts were harvested from the center of the hard palate. Patients ranged in age from 10 to 82 years old. Of 80 mucosae, 54 were harvested with periosteum, and periosteum was not retained in the defect bed. The other 26 mucosae were harvested without periosteum, which was therefore retained in the defect bed. The healing time increased depending on the defect size in both groups of patients retaining and not retaining periosteum. There was a significant relationship between the defect size and healing time in both groups (Spearman's rank correlation test, p < 0.0001 in both groups). In the two groups, there was no significant relationship between patient age and healing time in the patients with defect smaller than 1.99 cm or larger than 2.00 cm2. There were no significant differences in the rate of patients with pain and bleeding between the groups retaining and not retaining periosteum. In the group not retaining the periosteum, all 54 patients showed a flat or atrophic smooth surface at more than 6 months after epithelization and had no discomfort. However, 17 patients showed flat or atrophic smooth surface in the group retaining the periosteum and the remaining 9 patients showed hypertrophy at more than 6 months after epithelization, with accompanying discomfort. The rate of the patients with hypertrophy in the group of patients retaining periosteum was significantly high as compared with that in the group of patients not retaining periosteum (p = 0.000013, Fisher's exact test). In 26 patients retaining periosteum, the age of the patients with hypertrophic surface was significantly younger than that of the patients with flat or atrophic surface (p = 0.0010, Welch's -test), and the defect size in the patient with hypertrophic surface was significantly smaller than that of the patients with flat or atrophic surface (p = 0.0028, Welch's t-test). In conclusion, our study demonstrated that the existence of periosteum in the palate donor bed does not contribute to reduced healing time or reduced pain. Rather, retaining the periosteum caused hypertrophy of the donor site, leading to discomfort, especially in young patients with a comparatively small defect.     

Total upper eyelid reconstruction by single staged malar-cheek flap

We report a case of total upper eyelid reconstruction by a new technique after excision of an eyelid tumour. The eyelid was reconstructed by a horizontal, laterally based flap from just under the lower eyelid combined with a chondro-mucosal graft from the nasal septum. Surgical outcome was an excellent aesthetically reconstructed eyelid, which was mobile and properly gliding on the globe to achieve complete eye closure.KEY WORDS: Eyelid tumour, sebaceous carcinoma, upper eyelid reconstruction     

Total upper and lower eyelid reconstruction using deltopectoral flap

Total upper and lower eyelid unilateral full thickness reconstruction is a surgical challenge. A case of right orbital haemangioma with unilateral complete defect of total upper and lower eyelids with right orbital exenteration is reported, together with the surgical technique of reconstruction. Patient was a 24-year-old female who underwent right orbital exenteration with total upper and lower eyelid excision for orbital haemangioma presented after 3 weeks of the above procedure. In the first stage split thickness skin grafting is used to resurface orbital cavity raw area followed by staged reconstruction of total upper and lower eyelid reconstruction using pedicle deltopectoral flap. This reconstruction provided stable eyelid reconstruction to retain ocular prosthesis with concealed and minimal donor area. After reconstruction patient underwent rehabilitation with ocular prosthesis, now the patient is satisfied with cosmetically acceptable results.KEY WORDS: Deltopectoral flap, total eyelid reconstruction, total upper and lower eyelid reconstruction with DP flap     

The evaluation and treatment of upper eyelid paralysis

Patients with upper lid paralysis suffer from a loss of the blink reflex/response in the affected eye, leaving the eye vulnerable to a host of predatory insults. Partial or total impairment of the orbicularis oculi muscle, lagophthalmos, disruption of the lacrimal apparatus, upper lid retraction, and the unopposed pull of gravity on the surrounding paralyzed tissues all contribute to increased corneal exposure and an increased risk of exposure keratitis. Management of the upper lid in these patients must therefore focus on restoration of the effects of the blink reflex/response and prevention of corneal exposure. Relevant anatomy and pathophysiology are discussed. The initial treatment is supportive, with surgery reserved for those patients that fall into two categories: those who have failed nonsurgical treatment to protect the cornea and those who have been treated effectively with conservative measures but are faced with the prospect of long-term or permanent paralysis. A variety of surgical procedures that may be classified as either static or dynamic are discussed. Standard static procedures include lid loading and tarsorrhaphy, whereas the palpebral spring implant and the temporalis muscle transfer are classified as dynamic. The goal of the corrective procedures is to allow complete eye closure, thereby providing corneal protection, with minimal (1 mm or less) ptosis in the open position.     

The facial artery musculomucosal flap in the reconstruction of the cocaine-induced hard palate fistula

The versatility of the facial artery musculomucosal (FAMM) flap has been employed in the reconstruction of a number of defects in the head and neck region. Closure of the cocaine-induced palatal fistula is complex, in particular because of the poor quality local tissue. To date, the FAMM flap has yet to be reported in this situation. We describe our experience with one such case, detailing our rationale for choosing the FAMM flap, intra-operative technique, and recommendations for other surgeons with similar cases.Level of Evidence: Level V, therapeutic study.     

Reconstruction of full-thickness lower eyelid defects using a blepharoplasty technique with a hard palate mucosal graft.

The authors report a method of reconstruction of a full-thickness lower eyelid defect using a blepharoplasty technique utilizing excess skin of the lower eyelid with a hard palate mucosal graft. In all patients the hard palate mucosa took well, and good functional and aesthetic results were obtained. The most suitable indication of this technique might be for the defect occurring horizontally (for which direct closure is difficult to apply) and located in the lateral side of the lower eyelid (when a large amount of excess skin can be utilized). The authors conclude that although the shape and size of the defect to which this method can be applied is restricted, this is a useful option in the reconstructive methods of a full-thickness lower eyelid defect.     

An upper eyelid cyst from migration of a hard corneal contact lens

A migrated polymethylmethacrylate contact lens in the upper eyelid presented as a mass of unknown etiology. The lens had been unknowingly retained in the eyelid for seven years, after it had migrated through the conjunctiva of the superior fornix, and then moved in front of the levator aponeurosis and upper tarsal plate, where it lay encysted by conjunctiva. We believe that having sequestered conjunctival epithelium around the lens explains the minimal nature of the inflammatory and secretory responses necessary to allow such a protracted period of retention.
