The maxillary alveolar ridge separates the palate from the lip and clefts of the primary palate have a cleft of the alveolus as well. In the most common clefts of the primary palate, the alveolar portion of the cleft is located between the lateral incisor, if present, and the canine. The cleft may also pass between the central incisor and the lateral incisor, rarer forms of clefts may pass between the central incisor or more distally on the maxillary arch. There are still considerable differences of opinion as to the optimal time for closure of alveolar defects, with or without concomitant bone grafting. But the preferred time for the operation with bone graft is between age 9 and 11 before the canine teeth have fully erupted. As an alternative to primary bone grafting, Skoog developed the periosteoplasty, or "boneless bone graft" technique, in which periosteal continuity was established between maxillary segments by the transfer of local periosteal flaps from the anterior maxillary wall. this procedure, which takes advantage of the propensity of periosteum to form bone in young children, leads to the formation of new bone within the alveolar cleft in spite of the fact that no bone graft is used.This study attempts to defin the effectiveness of early alveolar cleft repair with gingivo-vestibular-mucoperiosteal flap.The results in 6 unilateral alveolar clefts and 1 bilateral alveolar cleft, which is corrected early by gingivo-vestibular-mucoperiosteal flap, have been satisfactory alveolar arch continuity and alveolar bone formation with tooth eruption.

Dacryocystography has been widely used in the assessment of the lacrimal passage system, particularly in patients with epiphora. The site of obstruction and presence of fistulas, tumors, diverticula, or calculi can be evaluated, so that therapy can be accurately planned. It has been reported by other authors about the results of dacryocystography in Korea, but there were not enough subjects to study. A retrospective study has been carried out on 171 patients(194 eyes) who have undergone dacryocystography for epiphora at Kangbuk Samsung hospital from December 1992 to June 1993, to assess age, sex, duration of epiphora, previous treatments, incidence rate of obstruction site of the lacrimal system, causes of lacrimal obstruction. The incidence rate of lacrimal system obstruction on dacryocystography was 172 eyes(88.7%). The most common site of obstruction was nasolacrimal duct(107 eyes, 55.2%) and then inferior canaliculus(30 eye, 15.5%), lacrimal sac(18 eyes, 9.3%) and common canaliculus(17 eyes, 8.8%). The most common cause of obstruction was unknown(89 eyes, 51.7%), and then chronic dacryocystitis (45 eyes, 26.2%), congenital(14 eyes, 8.1 %).
