RESUMO
Purpose: To assess the clinical profiles and outcomes of strabismus in pediatric patients with orbital wall fractures. Methods: A retrospective interventional study of all consecutive children of age ?16 years who presented with traumatic orbital wall fractures with and without resultant strabismus was conducted. The details of patient demographics, clinical features, interventions, and outcomes were obtained. Results: Forty?three children presented with traumatic orbital fractures to a tertiary care center. The mean age at presentation was 11 years and there was a male predominance (72.09%). Isolated floor fracture involvement was the most common (n = 24, 55.81%), and almost half of the children had a white?eyed or trapdoor fracture (n = 21, 48.83%). Twenty?six (60.46%) children had surgical repair of fracture(s). Manifest strabismus following orbital fracture was documented in 12 children (27.90%). Of these, an exotropia was noted in seven (58.33%), hypotropia in two (16.67%), hypertropia in one (8.33%), and esotropia in one patient (8.33%), while an exotropia with hypotropia was noted in one patient (8.33%). Restrictive nature of strabismus due to either muscle entrapment or local trauma was more commonly observed in 11/12 patients (91.66%). Primary position diplopia before orbital wall fracture repair was observed in four children and after repair was observed in two children with manifest strabismus. Four children underwent strabismus surgery post?fracture repair. Conclusion: An improvement in strabismus and ocular motility was noted in majority of the patients after fracture repair. The few that underwent strabismus surgery had a restrictive nature of strabismus. Trapdoor fractures and the nature of trauma in children vary compared to adults. Persistence of strabismus may be due to an excessive time interval between trauma and fracture repair or the extensive nature of trauma
RESUMO
Background: Severe cicatricial entropion in Stevens–Johnson syndrome (SJS) patients is difficult to treat and is associated with a higher recurrence rate. Also, entropion in the presence of lid margin mucous membrane graft (MMG) further complicates the surgical anatomy and approach. Purpose: To report a modified surgical technique of repairing severe upper eyelid cicatricial entropion in an SJS patient with history of lid margin MMG. Synopsis: Cicatricial entropion in patients with SJS is entirely different from trachomatous cicatricial entropion. The involvement of the lid margin with keratinization, tarsal scarring, persistent conjunctival inflammation, and unhealthy ocular surface affects the surgical approach and outcomes. Conjunctiva?sparing surgery with reconstruction of the lid margin using MMG, flattening and repositioning the anterior lamella, and covering the bare tarsus with MMG rather than leaving it raw are the necessary modifications in this technique from conventional anterior lamellar recession. The video demonstrates the surgical technique for harvesting and preparation of a labial MMG, the splitting of the anterior and posterior lamella of the lid margin, scar tissue release between the lash line and the tarsus, repositioning of the anterior lamella, and anchoring of the labial MMG. Highlights: Anterior lamellar recession combined with MMG wrapping the lid margin and bare tarsus offers good cicatricial entropion repair outcomes. Removal of fat and submucosa from the mucosal graft should be done for better cosmesis. Adequate separation of the scar tissues from the lash line and the tarsus is essential.
