Objective To evaluate the effects of lip repair on maxillofacial development of patients with unilateral cleft lip with or without cleft palate. Design Retrospective. Patients A total of 75 patients were recruited, including 38 surgical patients with complete unilateral cleft lip and alveolus and 37 patients with complete unilateral cleft lip and palate who had lip but not palate repair. As controls, 38 patients with no cleft were selected. All subjects were divided according to two growth stages: before the pubertal peak (GS1) and after the pubertal peak (GS2) Interventions Lateral cephalograms of all subjects were obtained. Main Outcome Measures Cephalograms were analyzed and compared in the study and control groups. Results The patients with unilateral cleft lip and palate in both GS1 and GS2 demonstrated an almost normal maxillary and mandibular growth with retroclined maxillary incisors. The patients with unilateral cleft lip and palate showed a shorter length of maxilla, a more clockwise-rotated mandible, and retroclined maxillary incisors. Conclusions There was an almost normal maxillary and mandibular growth but retroclined maxillary incisors in patients with cleft lip with or without cleft palate who had received lip repair only, indicating that lip repair may not have a negative impact on the maxillofacial development and influences only the inclination of the maxillary incisors. The shorter anterior-posterior maxillary length and larger gonial angle in patients with unilateral cleft lip and palate compared with those in patients with unilateral cleft lip and alveolus suggest that these variations in maxillary and mandibular growth may be a consequence of the cleft itself.

The primary and modifier genes that regulate normal maxillofacial development are unknown. Previous quantitative trait locus (QTL) analyses using the F2 progeny of 2 mouse strains, DBA/2J (short snout/wide face) and C57BL/6J (long snout/narrow face), revealed a significant logarithm-of-odds (LOD) score for snout length on mouse chromosome 12 at 44 centimorgan (cM). We further sought to validate this locus contributing to anterior-posterior dimensions of the upper mid-face at the D12Mit7 marker in a 44-centimorgan portion of chromosome 12. Congenic mice carrying introgressed DNA from DBA/2J on a C57BL/6J background were selected for submental vertex cephalometric imaging. Results confirmed QTLs, determining that short snout length (P < 0.05) and face width relative to snout length (P < 0.01) were present in the 44-cM region of chromosome 12. We conclude that one or more genes contributing to the shape of the maxillary complex are located near 44 cM of mouse chromosome 12.

Adenoids and tonsils are pharyngeal lymphoid tissue aggregation. Adenotonsillar hypertrophy is usually seen in children. Enlarged adenoid and tonsillar tissue in children causes snoring, sleeping disorders, failure to thrive, frequent upper respiratory tract infections and abnormalities in maxillofacial development. Surgical treatment performed for their removal is termed as adenotonsillectomy. This is one of the most commonly performed surgical procedures in children. The present study was conducted to compare the voice change using the GRBAS scale before and after adenotonsillectomy. This is a prospective study conducted for three months at the Department of Otorhinolaryngology in our tertiary care center. Voice of 35 children with adenotonsillar hypertrophy is analyzed by GRBAS scale in three stages before the surgery, three weeks after surgery and six weeks after surgery. The resulting voice quality improvement is noted in these children after adenotonsillectomy. This study showed that surgical procedures of adenotonsillectomy do not induce drastic adjustments in sound quality and can be performed safely in children. Post-operative voice changes are a significant concern issue among the parents of the children.

Unilateral maxillary clefts were created In 4-week-old rabbits by removing premaxillary-maxillary sutures. Four groups, five animals per group, were formed. Control animals (Group I, no clefts) helped determine normal values for facial growth. In Group II the clefts were unrepaired. In Group III each had a rib graft harvested and placed Into the alveolar defect only. In Group IV the cleft was completely grafted with multiple ribs to the nose. At six months postoperatively skeletons of all animals were directly measured and an orthogonal coordinate analysis compared maxillary and palatal growth among groups. Greatest deviations in growth were seen when the entire cleft was grafted; shortened maxillary development and nasal deflection to the clefted side occurred. Unrepalred clefts and grafts limited to the alveolus had maxillofacial development similar to that in unoperated controls. The location of grafts In clefts in infancy appears critical to avoid retarded maxillary growth.
