BackgroundThe purpose of this work was to determine the effectiveness and possible complications encountered with bilateral fascia lata lid suspension used to correct blepharoptosis in patients with Kearns-Sayre syndrome.MethodsThis was a retrospective study of seven patients with Kearns-Sayre syndrome who had a minimum of 1 year of follow-up. A bilateral fascia lata sling was used to correct the ptosis. Preoperative and postoperative measurements of the vertical lid fissure width (VFW) and marginal reflex distance (MRD) were performed. The Student’s t-test was used to analyze the results.ResultsThe mean preoperative VFW and MRD measurements were 4±2.45 mm and 0.14±0.92 mm, respectively. The mean postoperative VFW and MRD measurements were 7.71±1.85 mm, and 2.86±1.69 mm, respectively. All preoperative and postoperative values were considered to be statistically significant (P<0.01). Adequate elevation of the lids was obtained in all patients, both functionally and aesthetically. All of the patients showed a mild symmetric postoperative inferior version lagophthalmos, and one patient developed corneal ulceration and scarring due to corneal exposure and a weak Bell’s phenomenon.ConclusionThe surgical technique described to correct the blepharoptosis found in patients with Kearns-Sayre syndrome was found to be efficient and relatively safe. The correction should be conservative to decrease the risk of postoperative corneal damage that occurred in one patient.

One-stage correction of BPES is safe and efficient with the surgical techniques described.

BackgroundTo examine the immunohistochemical expression of heat shock protein 90 (Hsp90) and Ki-67 protein in human pterygium.Materials and methodsTissues obtained during pterygium surgery of 15 patients who underwent the bare-sclera procedure and 10 normal conjunctivae were studied. All of these pterygia were primary ones. Recurrent pterygia were excluded. Normal bulbar conjunctivas (2 x 2 mm) were obtained from the nasal region close to the limbus from patients during their cataract and retina surgeries. Immunohistochemical detection of Hsp90 and Ki67 was done using the streptavidin–biotin method in paraffin embedded tissue sections.ResultsThe percentage of cells stained for Hsp90 was greater for pterygium epithelium (76 ± 10.8) than for normal conjunctiva (1.4 ± 0.8). In each pterigyum sample more than 60% of cells were positive. The differences in positive cells between normal and pterigyum epithelium were highly significant for Hsp90 (P < 0,001).Pterygium epithelium also showed a higher percentage of cells that stained for Ki67 (10.1 ± 9.5) than for normal conjunctiva (2.1 ± 1.9). The differences in positive cells were also statistically significant for Ki67 (P < 0.01). Although there were significant differences in the majority of samples observed. It was noted that in some samples there was no difference between normal and pterygium epithelium for Ki67.ConclusionOur results indicate an abnormal expression of Hsp90 and ki-67 in pterygium samples when compared to normal conjunctiva.The finding of abnormal expression of levels of Hsp90 in pterygium samples can stimulate new research into pterygium and its recurrence.Virtual SlidesThe virtual slide(s) for this article can be found here: http://www.diagnosticpathology.diagnomx.eu/vs/1128478792898812

Purpose: Facial clefts are congenital anomalies classified by Tessier based on their anatomical position. Tessier 8 craniofacial clefts extend from the lateral canthus to the temporal region, including bone cleft at the frontozygomatic suture, and it is characterized by the interposition of a strip of skin at the lateral canthus that disrupts the continuity of the orbicularis muscle, preventing its normal functioning. Methods: This is a retrospective study of 6 patients with congenital eyelid coloboma, of whom 5 underwent surgery for the removal of dermolipoma and reconstruction of the lateral canthus. After surgery, the shape and symmetry of the lid fissure was restored, and motility was maintained. Vertical and horizontal measurements of the palpebral fissure were carried out before and after surgery. Results: Five cases of lateral colobomas were evaluated after surgical treatment up to a year post operatively. The surgical correction with limited resection of the tumor was very effective, and the resulting small horizontal scar almost disappeared over time. In all cases, motility was maintained, and there were no cases of symblepharon. After surgery, there was improvement in the shape and symmetry of the eyelid fissures. Conclusions: Tessier’ Number 8 facial cleft coloboma is characterized by the interposition of a skin strip, constituting a dermolipoma between the upper and lower eyelids that disrupts the continuity of the orbicularis muscle, and lateral bone alteration. The surgical correction of dermolipoma should be performed conservatively with limited resection of the tumor. A simple canthoplasty was very effective, and the small scar practically disappears over time. The absences of bone alteration in the cases presented suggest a unusual variation of lateral canthal cleft.

Excellent results were obtained by recessing the levator palpebrae superioris muscle aponeurosis with relaxing incisions and advancing it to overly the gold weight implant completely. Visibility of the implant in the pretarsal upper eyelid surface was minimized, extrusion was avoided, and good eyelid position was obtained.

The complexity of the surgical treatment increases when there is no possibility of rudimentary eye bulb preservation. In upper eyelid reconstruction, the authors adopted Mustardé's technique with fixation of the lower eyelid transposed flap to the levator muscle, leading this way to relatively good upper eyelid motility. The authors consider imperative that the upper fornix be reconstructed with adequate depth to allow perfect positioning of an aesthetic prosthesis, in this way improving the final aesthetic and functional results.

RESUMOObjetivo: Demonstrar a redução das complicações e melhora do resultado estético da correção do lagoftalmo paralítico com utilização de implantes de peso ouro através do recobrimento pela aponeurose do músculo levantador palpebral. Métodos: Foram estudados vinte e nove pacientes portadores de paralisia facial idiopática com evolução clínica superior a 4 anos submetidos à correção cirúrgica do lagoftalmo paralítico com a utilização de uma modificação da técnica do implante de peso de ouro recoberto pela aponeurose do músculo levantador palpebral (Gladstone,1996) entre junho de 1997 e dezembro de 2006. Nenhum deles havia se submetido previamente a tratamentos cirúrgicos. Resultados: Todos os pacientes apresentaram adaptação favorável dos implantes. Não houve casos de extrusão, deslocamento ou infecção, com melhora significativa da sintomatologia clínica e redução do lagoftalmo paralítico no período de acompanhamento pós-operatório que variou de 8 meses a 4 anos. Conclusão: Através da ampla dissecção da aponeurose do músculo levantador palpebral para recobrimento completo do implante do peso de ouro nós obtivemos excelentes resultados. O contorno da superfície cutânea pré-tarsal apresentou-se homogêneo, evitou-se a extrusão do implante e, comparativamente aos resultados apresentados pela técnica inicialmente descrita por Gladstone na qual realizava-se apenas a plicatura da aponeurose do músculo levantador palpebral sobre o implante de ouro, obtivemos um melhor controle do posicionamento final da pálpebra superior após o recobrimento do implante.
