Telecanthus and hypertelorism in frontoethmoidal meningoencephaloceles and the surgical correction of these conditions: Part II. A novel surgical approach in the treatment of telecanthus.
Frontoethmoidal meningoencephaloceles (MEC) are frequently associated with telecanthus (TC) and seldom with hypertelorism (HT). The correction of these orbital dysmorphisms are undertaken in the same setting as the surgical treatment of MEC. During several charity missions to Phnom Penh, Cambodia, the authors developed a simple surgical technique for the correction of TC that has not been described before. The results of this technique was evaluated as follows: in 58 patients, who underwent surgical treatment of MEC, the pre and postoperative inner canthal (ICD) and outer canthal distances (OCD) were measured; the interpupillary distance (IPD) was measured in 50 patients. Forty five (78%) out of the 58 patients showed a telecanthus before surgery; 39 (87%) of these 45 showed normal values after surgery, in the rest 6 (13%) the ICD could be decreased after surgery, however the values did not reach a normal range.A HT (including TC) was found in 10 patients presenting with MEC (17%) before surgery. Five (50%) of these patients did not show a HT in post surgical follow-up. In 3 (30%) of the remaining 5 patients showing persistent HT, the ICD alone could be decreased to a normal value (no TC), whereas in 2 (20%) others a TC was unchanged. Three patients with MEC had shown normal preoperative orbital morphometry. The mean follow-up was 9 months (range: 5-16 months). The reader is further referred to our previous paper for interpreting the orbital measurement values in Khmer Cambodians as pertinent to TC or HT.
