Long-Term Photogrammetric- and Panel Assessment-Based Outcome Study of Staged Reconstructive Approach for Hypertelorism Correction.

BACKGROUND

The surgical management of hypertelorism is challenging for plastic surgeons, and limited long-term outcome data are available. The purpose of this long-term study was to report a single-surgeon experience with a staged reconstructive protocol for hypertelorism correction.

METHODS

This retrospective study reviewed the records of patients with hypertelorism who were surgically managed by a single surgeon between 1978 and 2000. Bone (orbital box osteotomy and orthognathic surgery) and soft tissue (rhinoplasty and epicanthoplasty) surgeries were performed based on a patient-specific surgical protocol. Included patients were divided into a childhood group and an adolescence or adulthood group according to their age at orbital repositioning (≤12 and >12 years, respectively). Patients were invited for clinical interviews in February 2020 to evaluate whether requests for revision surgery had been made. The photogrammetric analysis-based hypertelorism index was calculated at preoperative and long-term postoperative times. Satisfaction with the long-term outcome was judged by both surgical professionals and laypeople.

RESULTS

In total, 14 patients with hypertelorism of different etiologies were included, with no request for revision surgery during an average follow-up of 29 years. The preoperative hypertelorism index was higher than the long-term postoperative evaluation (all, P < 0.05) for both childhood and adolescence or adulthood groups. Intergroup comparison revealed no significant difference for the hypertelorism index and panel assessment-based satisfaction with long-term outcome analysis (all, P > 0.05).

CONCLUSIONS

Considering the complexity and wide spectrum of clinical presentation of soft tissue and bone deformities in hypertelorism and current outcomes, the surgical approach to these patients should be staged and individualized for achievement of a balanced result between functional (orbital, occlusion, and psychosocial) and aesthetic parameters.
