The no. 0-14 cleft involves the midline of the face and cranium. It may include both a true and a false median cleft lip, with or without associated hypotelorism or hypertelorism. The no. 0 cleft is the most common of the craniofacial clefts. The objective of this study was to review the functional outcome and aesthetic results of the different techniques applied for each case. We have conducted a retrospective analysis of our series consisting of 32 cases of Tessier no. 0 cleft, in the period between 1997 and 2007. The patients were divided into 2 groups: those with the true median cleft and those with the false median cleft. The clinical findings, lip malformation, alveolar cleft, nasal appearance, septal involvement, associated deformities, and surgical procedures, were all reviewed. Holoprosencephaly was present in 9 cases, with a false median cleft upper lip and an absence of the premaxilla, septum, and columella (only 1 patient underwent lip and columella reconstruction at 2 years of age). Nine patients had an incomplete median cleft lip. Seven of these cases had associated median alveolar cleft, and 1 had an intranasal tumor, associated with lipoma of corpus callosum, characteristic of the Pai syndrome. Six cases of a bifid nose were seen, 2 of which were associated with an alveolar median cleft and hypertelorism. An isolated median alveolar cleft was present in 7 cases, 2 of them associated with a no. 30 cleft. This article presents a large series of Tessier no. 0 cleft, describing the differences between the false and the true median cleft. The surgical procedures may vary in relation to the type of involvement.

Background: Despite all benefits offered by mandible distraction, complications and long-term consequences need to be evaluated to define its safety and morbidity. Forty mandible distractions were studied. Panoramic mandible radiographs obtained preoperatively, during distraction, and during the postoperative period were reviewed, with the intention of evaluating development and complications of molar buds and teeth in the distraction area. Methods: The mean patient age was 8.1 years. Twenty-five patients had craniofacial microsomia (one associated with a no. 10 facial cleft), five had temporomandibular joint ankylosis, two had familiar cases of auriculocondylar syndrome, one had a Tessier no. 30 facial cleft, and one had Treacher Collins syndrome. The severity of mandible hypoplasia was Pruzansky grade I in four cases, grade IIA in eight cases, grade IIB in 16 cases, and grade III in one case. Mean radiographic follow-up was 44.8 months. Results: Molar buds located in the distraction area erupted without any deformity or displacement in 18 sides (45 percent). Fourteen cases presented distalization of a dental bud to a superior position in the mandibular ramus (four migrated back to the original position). Six molar buds presented perforations, four had shape deformities (two caused by dental fracture), and two had dental root injuries followed by root absorption lately. One case developed a dentigerous cyst. Conclusions: Almost half of the patients did not have any molar bud or tooth alterations after mandible distraction, and more than 20 percent presented only bud distalization. Therefore, preventive bud enucleation or tooth extraction should be avoided before mandible distraction.

The Tessier no. 5 facial cleft is an extremely rare congenital malformation. Only 26 cases have been described in the English-language literature. The cleft begins in the upper lip just medial to the oral commissure, extending across the cheek as a groove ending at the junction of the middle and lateral thirds of the lower eyelid. The bone involvement usually includes an alveolar cleft in the premolar region, extends across the maxilla lateral to the infraorbital nerve, up to the infraorbital rim and orbital floor. The goals of the surgical procedure include reconstructing the lower eyelid, repositioning the lateral canthus, closure of the labiomaxillary cleft, and restoration of the skeletal continuity (including the orbital floor defect) with bone grafts. We present six patients with the Tessier no. 5 facial cleft who have been treated in our combined centers and discuss the surgical options and difficulties faced in the reconstruction of this rare and challenging craniofacial malformation. To date, we have treated six patients (two with bilateral and four with unilateral clefts). Three of the patients with unilateral clefting had an associated no. 4 cleft and one patient with a bilateral cleft had an associated no. 3 cleft. This paper represents the largest series to date documenting surgery for patients with the Tessier no. 5 facial cleft.

Introduction:Number 3 cleft or oral-nasal-ocular cleft is a well-known entity that was described by Morian over a century ago. This malformation is a paranasal-medial orbitomaxillary cleft running across the lacrimal segment of the lower eyelid and over the lacrimal groove. The Tessier number 3 naso-ocular cleft represents one of the most difficult and challenging malformations to correct for the reconstructive surgeon. We have conducted a retrospective analysis of our series consisting of 21 cases. Objective:The objective was to review the functional outcome and aesthetic results of the different techniques applied for each case. Materials and Methods:From 1997 to 2007, 21 patients with a Tessier number 3 cleft were treated in our craniofacial units. The clinical findings, tomographic studies, and surgical procedures were reviewed and analyzed. We have discussed our protocol of the treatment. Results:We have treated facial malformation in 2 craniofacial centers. Fourteen patients were evaluated in the first year of their life, with an average age at presentation of 3 years. Twelve patients were female, and 9 were male; 6 patients had amniotic bands in limbs, 5 patients had an association with Tessier number 11 cleft, 3 patients with number 9 cleft, and 1 with number 7 cleft. Related to cleft lip, 10 patients had bilateral cleft lip, and 8 patients had unilateral cleft lip. Three patients did not have any involvement of the upper lip. The alar base was deviated upward in 19 patients, 11 cases had severe anatomic alteration with the lateral border of the ala above the medial canthus, and 8 cases had a mild dislocation. Nine cases of lacrimal duct obstruction and 8 cases of lacrimal duct extrophy were identified. Twelve patients had a lower eyelid coloboma of varying grades, and there were 2 cases of microblepharia. Aiming the soft tissue reconstruction, eyelid, nose, and upper lip were evaluated regarding their position, absence of tissue, and position of medial canthus and ala. Twelve of our patients underwent correction in the same moment, their medial canthus rotated upward and the ala downward, using the contralateral side as the reference. The lip was treated using a Millard-like technique. Neo-conjunctivorhinostomy was performed in the same moment in 2 patients or later in 1 case. Four patients had plagiocephaly due to the cranial involvement, and they were submitted to cranioplasty. Three had neurosurgical approach and advancement of the frontal bandeau. One adult patient received an acrylic plate to reshape the frontal area. Conclusions:Tessier number 3 cleft is one of the most difficult and challenging malformations to correct for the reconstructive surgeon. Besides the difficulties of its treatment, patients with Tessier number 3 cleft may achieve good results when the team has good skills.

For many years, surgeons have sought a method to treat severe facial deformities without using bone grafts and extensive surgery. Distraction osteogenesis offers this promise. The technique used in mandibular hypoplasia follows the basic principles proposed by Ilizarov which states that the device must be elongated 1 mm per day to create optimal bone production. Despite the widespread implementation of this recommendation to include the 1-mm/day separation, doubt still exists as to whether this is the optimal treatment regimen. Intraoral devices with percutaneous activator pins were used in 16 patients with hypoplastic mandibles. The results of distraction were documented by panorex and cephalogram of the mandible. The length of the ramus as well as multiple mandible dimensions and facial angles were measured. The panorex and cephalogram of the mandible were effective in demonstrating the significant increase in length of the mandible and ramus, as well as the entire mandible, but there was no correlation between the stretching obtained by the distraction device and that measured by the radiographic studies. The S-N-B angle was the only facial angle in which there is a statistically significant increase measured and this appeared to be related to a mandible rotation. It is concluded that the mandible distraction (using an intraoral device and an external activator pin) was effective in increasing the ramus length and both the panorex and the cephalogram were effective in demonstrating this morphologic change. There was no correlation between the clinical result and the radiographic studies demonstrating that the clinical judgment still has a significant role in controlling mandible distraction.

The absence of an eyebrow, either partial or total, has been observed in patients with craniofacial clefts, such as the Tessier 9 to 13 cleft. Several techniques have been used to improve the appearance of the region, such as island scalp flaps and scalp strip grafting, with limited or marginally satisfactory aesthetic results. The authors report 2 patients with craniofacial clefts in whom a novel technique combining 2 separate surgical approaches, micrografting and tattooing, was used. The use of micrografting with single or double hair units, properly angulated, produces natural-looking and satisfactory results with a minimum of morbidity. Excellent volume and appearance of the eyebrow may be achieved in a single session using this technique. Tattooing performed subsequently over the microimplanted hairs provides the illusion of greater density to the eyebrow, resulting in an appearance closer to normal.

Absence of half-nose is an extremely rare congenital malformation, which has a devastating impact on the patient and the family. A review of indexed English-language literature found 91 cases of half-nose, including 50 patients with proboscis lateralis. Pathogenesis is not clear, and the reported cases have sporadically occurred. Many aspects must be considered when reconstructing a congenital half-nose, such as timing of surgery, type of tissue to be used and the need to reconstruct nasal airway. The aim of this article is to present personal experience in seven cases of half-nose reconstruction, in order to review the literature regarding to this rare entity, highlighting aspects of incidence, pathogenesis and surgical treatment. Nasal reconstruction was performed at ages of 5-7 years to minimise psychological trauma. Forehead skin demonstrated to be an excellent donor site to re-surface the nose. For the inner lining, contralateral cutaneous nasal flap was our preference. Concerning the nasal framework reconstruction, alar contour was restored using a cartilage graft from the lower portion of ear tragus and concha.
