Background: Common surgical techniques aim to turn the entire vomerine mucosa with vomer flaps either to the oral side or to the nasal side. The latter approach is widely performed due to the similarity in color to the nasal mucosa. However, we lack a histologic description of the curved vomerine mucosa in cleft lip and palate malformations. Methods: We histologically examined an excess of curved vomerine mucosa in 8 patients using hematoxylin–eosin, periodic acid–Schiff, Elastin van Gieson, and Alcian blue stains. Tissue samples were obtained during surgery at 8 months of age. Results: Our histological analysis of the mucoperiosteum overlying the curved vomer revealed characteristics consistent with those of an oral mucosa or a squamous metaplasia of the nasal mucosa, as exhibited by a stratified squamous epithelium containing numerous seromucous glands. Some areas showed a palisaded arrangement of the basal cells compatible with metaplasia of respiratory epithelium, but no goblet cells or respiratory cilia were identified. Abundant fibrosis and rich vascularity were present. Conclusion: The vomer mucosa showed no specific signs of nasal mucosa. These findings should be considered in presurgical cleft orthopedics and palatal surgery for further refinement. Shifting the vomer mucosa according to a fixed physiologic belief should not overrule other important aspects of cleft repair such as primary healing and establishing optimal form and function of palatal roof and nasal floor.

Chromosome 17 duplication is correlated with an increased risk of developmental delay, birth defects, and intellectual disability. Here, we reported a female patient with trisomy 17 on the whole short arm with bilateral complete cleft lip and palate (BCLP). This study will review the surgical strategies to reconstruct the protruding premaxillary segment, cleft lip, and palate in trisomy 17p patient. The patient had heterozygous pathogenic duplication of chromosomal region chr17:526-18777088 on almost the entire short arm of chromosome 17. Beside the commonly found features of trisomy 17p, the patient also presented with BCLP with a prominent premaxillary portion. Premaxillary setback surgery was first performed concomitantly with cheiloplasty. The ostectomy was performed posterior to the vomero-premaxillary suture (VPS). The premaxilla was firmly adhered to the lateral segment and the viability of philtral flap was not compromised. Two-flap palatoplasty with modified intravelar veloplasty (IVV) was performed 4 months after. Successful positioning of the premaxilla segment, satisfactory lip aesthetics, and vital palatal flap was obtained from premaxillary setback, primary cheiloplasty, and subsequent palatoplasty in our trisomy 17p patient presenting with BLCP. Postoperative premaxillary stability and patency of the philtral and palatal flap were achieved. Longer follow-up is needed to evaluate the long-term effects of our surgical techniques on inhibition of midfacial growth. However, the benefits that the patient received from the surgery in improving feeding capacity and facial appearance early in life outweigh the cost of possible maxillary retrusion.

Late Postoperative Period

Surgical repair of cleft palate is quite difficult because it aims not only to eliminate the anatomical defect of the palate, but also to ensure normal functioning, including speech. Moreover, successful surgery implies no or minimal deformation of the middle face that can be corrected in the late postoperative period. No doubt that primary surgery (both in terms of technique and time) is crucial for further growth and development of the maxilla. However, surgical techniques and the age of primary cleft palate repair vary between different clinics, which makes this literature review highly relevant.

AbstractCleft lip and palate are facial and oral malformation due to failures in the embryologic craniofacial development during early pregnancy. A unilateral cleft lip and palate is the most common type, whereby the upper lip, the orbicularis muscle, the alveolar bone, the floor of the nose, and the hard and soft palate are interrupted, creating an open communication between nasopharynx and oropharynx. Patients with a cleft lip and palate are treated in specialized cleft centers by a multidisciplinary team. Having cleft lip and/or palate has a noteworthy impact on quality of life and psychosocial functioning. Postoperative scarring is a common cause of patient dissatisfaction. The goal of cleft lip surgery is to close the lip, provide optimal function in terms of speech, mastication, dental protection, breathing and feeding, and provide an aesthetically pleasing facial scar. Precise surgical technique and adequate aligning of anatomical structures is important for the postoperative aesthetic result and scar formation. Different surgical techniques are available for this purpose. Optimal scar management can be divided in surgical (precise surgical technique, planning, and adequate aligning of anatomical structures) and nonsurgical methods (botulinum toxin, silicone application, carbon dioxide fractional laser).

Morphological features and immunoreactivity for cytokeratin (CK), glial fibrillary acidic protein (GFAP) and neuron-specific enolase (NSE) of three canine neuroepitheliomas and three canine ependymomas were investigated. Neuroepitheliomas were in three German shepherds as intradural-extramedullary solitary masses, with spinal cord displacement between T10 and L2. Histologically, they contained tubules and acini, lined by epithelial cells with focal squamous metaplasia, rosette-like structures, and polygonal to spindle-shaped cells between tubules. Acini were empty or filled with a homogeneous, eosinophilic periodic acid-Schiff (PAS)-positive material. Mitotic indices varied from low to moderate. Ependymomas occurred in the third (two cases) and fourth ventricle in adult boxers. Histologically, they were composed of cells with an ill-defined, scant amphophilic cytoplasm, with a central round euchromatic nucleus; cells formed pseudorosettes, with a central fibro-vascular stroma. Neuroepitheliomas stained for CK, but ependymomas did not. Both failed to stain for GFAP, NSE, or phosphotungstic acid hematoxylin (PTAH). Thus, antibodies to cytokeratin are useful to distinguish neuroepitheliomas from ependymomas.

Objective: In unilateral cleft lip and palate, the reconstructed nasal floor is sometimes uplifted regardless of the reconstructive method used. We used a 5-0 absorbable anchoring suture, the oronasal transfixion suture (ONT suture), to fasten the reconstructed nasal floor to the orbicularis oris muscle to prevent this deformity. This study was performed to evaluate the effects of the ONT suture. Design: Blind retrospective study of photography and chart review. Setting: Shinshu University Hospital, tertiary care, Nagano, Japan. Private practice. Patients: Ninety-three consecutive patients with unilateral complete cleft lip and palate who had undergone primary nasolabial repair in our department and affiliated hospitals between 1999 and 2011 participated in this study. Finally, 45 patients were included. Interventions: The ONT suture was put in place at the time of primary nasolabial repair. Main Outcome Measure: The height of the nasal floor was evaluated on submental view photographs at 5 years old. Results: The ONT suture was applied in 21 patients. The height of the nasal floor on the cleft side was significantly closer to that on the noncleft side with the ONT suture than without the ONT suture ( P = .008). Conclusions: The ONT suture is effective to prevent uplifted nasal floor deformity on the cleft side// in unilateral complete cleft lip and palate at the time of primary nasolabial repair.

Aspergillus Infection

Liver transplantation is the only available treatment for some patients with end-stage liver disease. Despite reduction in mortality rates due to advances related to surgical techniques, intensive medical management and immunosuppressive therapy, invasive fungal infections remain a serious complication in orthotopic liver transplantation. We report the case of an 18-year-old male diagnosed with autoimmune cirrhosis in 2009 who was assessed and listed for liver transplantation for massive variceal hemorrhage. One year after listing a successful orthotopic liver transplantation was performed. Uneventful early recovery was achieved; however, he developed pulmonary and neurological Aspergillus infection 23 and 40 days after surgery, respectively. Antibiotic therapy with voriconazole and amphotericin was started early, with no major response. Neuroimaging revealed multiple right frontal and right parietal lesions with perilesional edema; surgical management of the brain abscesses was performed. A biopsy with periodic acid-Schiff and Gomori stains revealed areas with mycotic microorganisms morphologically consistent with Aspergillus, later confirmed by culture. The patient developed necrotizing encephalitis secondary to aspergillosis and died. Necrotizing encephalitis as a clinical presentation of Aspergillus infection in an orthotopic liver transplant is not common, and even with adequate management, early diagnosis and prompt antifungal treatment, mortality rates remain high.
