Objective: Frontoethmoidal meningeoencephaloceles (MEC) are frequently associated with telecanthus (TC), and seldom with hypertelorism (HT). These orbital dysmorphisms are corrected during the interdisciplinary surgical treatment of the celes.
Methods: The authors developed a novel technique to correct telecanthus during several charity missions to Cambodia, where they treat MECs, which was evaluated by respective orbital measurements. The correction of an orbital dysmorphism mandates the knowledge of age and gender related normal values in that particular ethnic group, from which the patient arises. Thus it appeared sensible to perform a study of the normal anthropomorphometric parameters of the orbit in Khmer Cambodians. We measured the inner canthal distance (ICD), outer canthal distance (OCD) and interpupillary distance (IPD) in 688 normally appearing Khmer Cambodian subjects (age range: 1-40 years; 344 females and 344 males). In 58 patients operated for MEC (mean age: 9.5 years; age range: 11 months – 23 years; 26 females and 32 males) the pre and postoperative ICD and OCD were measured. Pre and postoperative IPD was measured in 50/58 patients.
Results: Preoperatively, 45 patients showed a TC, 10 had an additional HT (with TC) and 3 showed no increase in the orbital distances. Among the 45 patients demonstrating a TC, 39 could be successfully corrected. In the remaining 6 patients the ICD did not reach normal values but was significantly decreased. 5/10 patients with HT showed a corrected status in the postoperative follow-up examination.
Conclusions: We have evaluated the efficacy of our surgical technique in correcting telecanthus and hypertelorism adapted for conditions in a „third world“ country. This technique has not been published before.
