Hallermann Streiff syndrome: Cranio-facial manifestations systematic review and report of two cases

Hallermann Streiff syndrome (HSS) is a rare congenital abnormality with about 200 case reports in the literature. Its etiology is unknown although it may be due to a sporadic mutation. Diagnosis is based on the association of craniofacial malformation, dental abnormalities, hypotrichosis, atrophy of the skin, proportionate nanism, congenital cataract and bilateral microphtalmos. Cranio-facial deformities are the main signs detected and the most easily recognizable. We report cranio-facial and oral signs from a systemic literature review, and illustrate our findings with two of our patients diagnosed with HSS. Common cranio-facial manifestations are craniofacial malformation with a « parrot beak » nose, micrognathia, aprominent skull, sutures closing anomaly, malocclusion, dental anomalies, eyebrows and eyelash lack and atrophy of the nose skin. Knowledge of these signs should allow for early diagnosis and adequate treatment and follow up.

Correction of lip and nasal deformities in bilateral cleft operated with Le Mesurier procedure

INTRODUCTION

Bilateral cleft lip surgery recently evolved with the generalization of cheilorhinoplasty replacing cheiloplasty alone. The aim of this study was to analyze lip and nasal deformities of bilateral cleft lip operated on with the Le Mesurier procedure, and then to evaluate possible secondary surgical solutions used in our Cleft Center.

PATIENTS AND METHODS

We retrospectively reviewed a total of 39 patients born between 1991 and 2009 with a bilateral cleft all type included (isolated lip, lip and alveolar, associated or not with a cleft palate), all treated at the Caen University Hospital with a Le Mesurier procedure for the primary cleft lip closure. We studied population characteristics, the number of secondary surgical procedures for lip and nasal deformities. We analysed therapeutic approaches of the different secondary surgical procedures used and their morphological results.

RESULTS

85% of patients needed at least one secondary surgical procedure, 28% two procedures, 15% three procedures and 8% four or more procedures. Median age at secondary surgery was 6,8. 79% had a "scar repositioning", 33% managed the vermilion, 18% a restoration of the volume of the lip, 12% a philtral tissue sacrifice, 9% a procedure on Cupid's bow, 24% a surgery for nasal tip projection, 45% a columella lengthening and 58% a reposition of the alar base.

DISCUSSION

Le Mesurier procedure for bilateral clefts leads to deformities that require secondary surgical procedures. We propose an algorithm to manage loop scar in this procedure.

Labiomental sensation after segmental mandibulectomy and inferior alveolar nerve preservation for osteoradionecrosis

Advanced mandibular osteoradionecrosis requires a segmental mandibulectomy with reconstruction using a free fibular flap. The conservation of labiomental sensation by lateralization of the inferior alveolar nerve is unusual during a segmental mandibulectomy. A protocol for the evaluation of labiomental sensation has been created for the clinical follow-up of operated patients. The patients included were patients with mandibular osteoradionecrosis who underwent a segmental mandibulectomy with reconstruction by free fibular flap and whose pre-operative labiomental sensation was preserved. All patients were followed-up by the same examiner and operated on by the same surgeon. The neuro-sensitive examination analyses the different forms of sensation at 1 week and at 12 months postoperatively. Between May 2017 and May 2018, 3 consecutive patients were assessed. The results of the labiomental sensitive evaluation using our evaluation protocol attest to the preservation of labiomental sensation. The operating time was increased by an average of 35 min per surgical procedure. The conservation and re-routing of the inferior alveolar nerve in segmental mandibulectomy with fibula free flap reconstruction in patients with osteoradionecrosis allows for the preservation of labiomental sensation, which improves the quality of life of patients. Our protocol can be used in all surgical procedure that affect sensibility.

[Palato velar fistulae in cleft palate]

Palatal fistulas after primary closure of a cleft palate are extremely variable ranging from 15 to 35%. When they are symptomatic, these fistulas affect feeding (nasal regurgitation to liquids, discharge, bad smells) and phonation (hypernasality that can hinder the precise assessment of velar incompetence). First of all, it is important to analyze the cause of the fistula, it helps to avoid early recurrences. The correction must apply to respect the 2 mucosal planes (nasal mucosa and oral mucosa), the only guarantee of surgical success. Different techniques are usually described: lingual flap, lifting of all palatal mucosa, flap hinge, blaster, FAMM. In all cases, postoperative care plays a key role in the success of the surgical correction.

Impact of early intravelar veloplasty at six months on mandibular growth in patients with Pierre Robin Sequence

Pierre Robin Sequence (PRS) combines mandible microretrognathia, asynchronism of the pharynx and tongue, glossoptosis and, in some cases, cleft palate. Its principal functional consequences are respiratory and feeding problems during the neonatal period. In this study, we focused on the impact of early closure of the cleft at six months on mandibular growth in patients with PRS. We performed a retrospective study of 15 patients followed for PRS and undergoing surgery performed by the same senior surgeon (HB) at our cleft center between 2005 and 2012. These patients underwent early closure of the cleft (at a mean age of 5.87 months) by intravelar veloplasty, as described by Sommerlad. Only one article with exploitable data analyzing facial and mandibular growth in a cephalometric study of children with PRS has been published. The children in this series, constituting the control group for our study, underwent veloplasty between the ages of 12 and 18 months, often accompanied by labioglossoplasty, and the cephalometric study was carried out between the ages of four and seven years. We compared this control group in which surgery was performed at 12-18 months with our series of children undergoing surgery at six months, in a cephalometric study based on teleradiographic profile measurements performed between the ages of four and seven years. We found that early closure of the cleft soft palate yielded results identical to those for the control group in terms of mandibular growth, without the need for labioglossopexy. Finally, early intravelar veloplasty led to early functional improvement in terms of speech and phonation.

Tessier number 4 bilateral craniofacial cleft associated with amniotic band syndrome: 22 years of follow-up

Tessier clefts are a very rare entity. Number 4 Tessier cleft is describe like an orbito-facial cleft with trajectory between the lower eyelid and the lip. We report management of a bilateral number 4 Tessier cleft with amniotic band syndrome with 22 years of follow-up. After reviewing literature, we talk about difficulty to manage these kinds of rare Tessier clefts.

Congenital Midline Upper Lip Sinuses

Congenital sinuses of the upper lip are rare congenital malformations. There have been only 40 cases described in the literature. We report 3 cases of congenital midline upper lip sinus in Caucasian children. Two of those lesions were associated with other anomalies (complete cleft palate and hemifacial macrosomia or submucous cleft palate with bifid uvula). The pathophysiology remains unexplained yet. Congenital upper lip sinuses can be considered as possible microforms of cleft-lips. Associated anomalies are frequent and must be sought. The treatment is a full excision of the sinus tract and of the skin around the punctum in order to avoid risks of recurrence.

Study of the mechanical reliability of an S-shaped adjustable osteosynthesis plate for bilateral sagittal split osteotomies. Study on 15 consecutive cases

INTRODUCTION

The main challenge during the osteosynthesis of a bilateral sagittal split osteotomy (BSSO) is to take into account the correct position of the condyle. Adjustable plates can be used to fine-tune the final occlusion without changing the osteosynthesis. A new type of adjustable plate is presented in this article. The aim is to assess the mechanical reliability of this system during the surgery and during the healing period, thanks to a preliminary prospective on 15 consecutive cases.

MATERIAL AND METHODS

The bridge of the plate studied here has an "S"-shape and can be bent in two different planes. Fifteen patients presenting a maxilla-mandibular disharmony have been operated on with this device. Clinical results were evaluated three months postoperatively and the mechanical reliability of the device was studied prospectively from teleradiographies of 15 patients operated on in our department.

RESULTS

This study shows good results, with respect to the mechanical reliability of this S-shaped adjustable plate, three months postoperatively corresponding to the bone-healing period. Radiographic observations did not show any significant displacement at the osteosynthesis site.

DISCUSSION

This preliminary study shows the mechanical reliability of this new S-shaped adjustable plate. Its semi-rigid character may allow for certain condyle position adaptability. No plate fracture was reported for this 15 patient series. These encouraging results have to be confirmed on a larger series.

Management of Large Maxillomandibular Osteofibrous Dysplasia as Part of a Humanitarian Mission

PURPOSE

Maxillomandibular ossifying fibroma is a benign tumor that affects young adults. Complete excision can allow satisfactory management with no recurrence. During a humanitarian mission, one is confronted with many types of damage from these fibromas. Their management requires wide resection (mandibulectomy interrupter or maxillectomy) and free flap reconstruction. However, technical conditions during a humanitarian mission might not allow the performance of a free flap reconstruction. How can such patients be managed? Should these patients receive a straightforward intervention performed on site during the mission or should they go to another country with a technical platform suitable for microsurgical reconstruction?

PATIENTS AND METHODS

During a humanitarian mission in Ouagadougou, Burkina Faso, 6 patients with large ossifying fibromas traveled to France to undergo wide excision of the lesion and free flap reconstruction using the fibula. The Enfants du Noma paid for the travel and medical costs.

RESULTS

No flap was lost. Four patients (67%) had local (disunity of scar or local infection) or general (malaria) complications that quickly resolved.

CONCLUSIONS

Most teams agree that free flaps should not be performed during humanitarian missions, and only 1 German team practices in Sokoto, Nigeria. Therefore, medical travel is an attractive solution that allows optimal management and requires financial assistance from humanitarian organizations.

[Child care management in maxillofacial humanitarian mission]

Our practice in a humanitarian (or crisis) context differs from what we experience in daily practice. There are several reasons for this. First, the diseases encountered are sometimes unfamiliar, such as sequelae of noma, or the presentation of familiar diseases may be unusual, such as facial malformations seen at a late stage. Secondly, these missions take place in developing countries, and consequently, evaluation and anticipation of possible malnutrition should be considered, especially because facial diseases themselves may be responsible for nutritional problems. Lastly, conditions are often difficult, occurring in an unusual environment, and we sometimes have to face communication and equipment problems. The goal of our work, based on a 15-year experience (in Bamako and Mopti with the Association "Santé et Développement", and in Ouagadougou with the organization "Les enfants du noma") and the analysis of literature, is to point out these features and maybe to be helpful to others.

Spinal cord metastasis of squamous cell carcinoma of the maxillary sinus

INTRODUCTION

Squamous cell carcinomas arising from the maxillary sinus have been rarely reported. The authors report the original case of a patient with squamous cell carcinoma of this site with an unusual clinical course.

CASE REPORT

A woman presented with squamous cell carcinoma of the maxillary sinus that was only diagnosed 6 months after onset of symptoms. At the time of diagnosis, the tumour had spread to the brain via the maxillary nerve and to the skin. The patient was treated by chemotherapy and radiotherapy. Four months after stopping treatment, the patient presented Brown-Sequard syndrome, for which imaging examinations were performed, demonstrating a spinal cord metastasis from her squamous cell carcinoma.

DISCUSSION

This case of squamous cell carcinoma presents several unusual features: the maxillary sinus is a rare site of squamous cell carcinoma and progression and distant metastasis have been only exceptionally described in the literature.
