be excluded as also being causes. 5 The similar features and mechanisms of hemifacial spasm and synkinesis could only be explained by enhanced motoneuronal excitability or ephaptic transmission because hemifacial spasm does not have substantial axonal injury and regeneration. Enhanced motor neuronal excitability could also not be ruled out due to the presence of lateral spread responses. 6
BACKGROUND: Cleft lip and palate (CLP) is one of the most common congenital deformities involving intervention in several sub-specialties. AIM: The present study was conducted to investigate the amount of maxillary advancement obtained by three different methods. METHODS: A retrospective comparative study was conducted on 24 CLP patients who were treated with three surgical maxillary advancement techniques: Group A was treated with Le Fort I (LFI) orthognathic surgery with bone grafting and rigid fixation (LFI). Group B was treated with intraoral maxillary bone distraction (MIDO). Group C was treated with orthodontic traction by facemask (orthodontic facemasks [OFM]) plus corticotomy. All pre-operative data were collected, which included intraoral and extraoral clinical photos and dental casts. Pre-operative radiographic assessment was compared with post-operative values using digital panorama, multi-slice computed tomography and lateral cephalometric X-ray measuring Sella-nasion-A point; point A-nasion-point B points, with a follow-up period of 6 months. RESULTS: All approaches showed statistically significant success in maxillary advancement with p < 0.01. LFI has produced the highest advancement obtained with regard to the pre-operative advancement required (8.6 ± 1.4) and post-operative advancement achieved (7.8 ± 0.8). MIDO technique is an alternative method to LFI, but it gives less achieved post-operative maxillary advancement (6.25 ± 0.8) and is indicated for moderate cases. OFM gave the least advancement results; however, it has been the most convenient less-invasive method and was more suitable for unsevere cases. CONCLUSIONS: The three approaches produced satisfactory results in rehabilitating deficient maxilla in cleft patients, although each technique has limitations and indications. Future research is recommended to assess the technique’s long-term stability.
BACKGROUND:Robinow Syndrome is an extremely rare genetic disorder characterised by abnormalities in head, face and external genitalia. This disorder exists in dominant pattern with moderate symptoms and recessive pattern with more physical and skeletal abnormalities. It was first introduced by Menihard Robinow in 1969. It was related to chromosome 9q22 ROR2 gene related to bone and cartilage growth aspects.CASE PRESENTATION:A 17-year-old Egyptian male presented to National Research Centre Orodental genetics Clinic with typical features of short stature and facial dysmorphism weighted 50 Kg and measured 150 cm height complaining of facial dis figurement. There was no significant prenatal history, and family history was negative for congenital disabilities and genetic disorders. Clinical examination revealed macrocephaly and special facial features as prominent forehead, deformed ear pinna, hypertelorism, flat nasal tongue tie, deficient malar bone, bow-shaped upper and lower lips and dimpled chin. Orally the patient suffered from tonetie, gingival hypertrophy and dental malalignment. The orthopantomogram showed multiple impacted teeth. The physical examination revealed that the patient had deformed spine, short limbs with ectrodactyly, micropenis & hypospadias. Surgical management included correction of midface deficiency with zygomatic augmentation, closed rhinoplasty for the broad nose, lips muscles release and tongue tie relief. The patient is currently undergoing orthodontic treatment for his teeth.CONCLUSION:Improvement of facial features and a good psychological impact on the patient and his family.
Purpose: to compare and assess the results obtained by using 2 different surgical techniques that utilize two stage palatoplasty to repair the palate, Furlow's technique and intravelar veloplasty. Material and Methods: This study was performed on 14 patients suffering from cleft palate, patients were divided into 2 groups, in group I Furlow's technique was used in palatal repair, in group II IVVP technique was used in palatal repair. All cases were selected from the Outpatient Clinic of the Faculty of Dental Medicine, Al-Azhar University for Girls. Results: Postoperative results of the MRI showed that the velum and the length of the muscle has become longer in each group, even though, there was no significant change between both techniques. The postoperative results of the nasopharyngeal endoscope proved that the increase in the levator muscle length increased the movement of the velum, in each group, however, between both group there was no significant difference. Conclusions: Both Furlow palatoplasty and intravelar veloplasty are efficient techniques that can be used in the repair of cleft soft palate. Both techniques can lengthen the soft palate together with palatal muscle reorientation; without the need to raise large mucoperiosteal flaps from the hard palate. Both techniques, with their modifications had shown success in the primary closure of different varieties and sizes of cleft gaps. The two stage palatoplasty can eliminate the need to raise large mucoperiosteal flaps from the hard palate.
