RESUMEN

Proboscis lateralis (PL) is a rare congenital craniofacial anomaly and it is represented by rudimentary, tube-like nasal structure measuring 2-3 centimetre (cm) length and generally attaches to medial canthal region. A 22-month-old male patient was referred to our clinic with a PL hanging from the right medial canthus and a coloboma on the medial third of the right lower eyelid. Physical examination revealed that the PL was 4 cm long and 1.5 cm in diameter. There was a blind cavity with dimple at its distal segment. The right side of the nose and the nasal airway was aplastic. Before surgical correction, neuroradiological evaluation should be performed to obtain the characteristics and relationship of the lesion with adjacent structures and associated anomalies Many reconstructive options have been described in the literature, however, these options are insufficient to obtain natural contour and define alar crease, especially. We described the laterally-based skin flap from the medial wall of the left heminose and adapted to the lateral edge of the de-epithelialized skin of PL for defining supra-alar crease.

RESUMEN

Congenital absence of the nose or arhinia is an exceptionally rare craniofacial malformation, and the pathophysiology of the arhinia is still unknown. Most arhinia patients can have difficulties with breathing and feeding due to the absence of the nose, nasal cavities, and associated problems. A 38-day-old female patient was referred to our clinic with arhinia. Physical examination revealed the complete agenesis of nasal structures as the nasal bones and vestibulum nasi. The region of the absent nose was flat and firm at palpation. Congenital arhinia may occur with other associated malformations such as ocular, ear, palate, and gonadal. Therefore, it is recommended to evaluate computed tomography/magnetic resonance imaging in the postnatal period. Additionally, a radiological evaluation will help nasal reconstruction by documenting changes in nasal and maxillary anatomy over time. Due to the limited number of arhinia cases presented, the surgical management of this condition has not been standardized. We presented the pyramid-shaped cartilage grafts for the nasal framework and an expanded paramedian forehead flap for the skin coverage for reconstruction of arhinia.

RESUMEN

BACKGROUND: Infantile Hemangiopericytoma (HPC)/Solitary Fibrous Tumor (SFT), a vascular tumor of head and neck region, can be congenital or arise during the first year of the life. As the infantile form of hemangiopericytoma has a better course than the adult form, surgical excision is recommended. Case Report: A full-term neonate presented with a congenital right temporal soft tissue mass. MRI revealed a highly vascular mass with a hemorrhagic and possible necrotic core without intracranial extension. The lesion grew in 2 weeks from 4x4 cm to 9x7 cm. Histologically, a hypercellular spindle cell mesenchymal neoplasm had prominent staghorn vessels, alternating with hypocellular areas. Mitotic activity was low(1-3/HPF) and necrosis was absent. Conclusion: Infantile HPC/SFT of head and neck can grow rapidly during the infantile period. Complete excision without mutilating surgery should be curative.

RESUMEN

The cleft lip and palate (CL/P) define a heterogeneous group of congenital deformities, which are morphologically highly diverse, with a complex and multifactorial etiology. Affected children may experience social problems due to negative effects on speech, hearing, facial appearance, as well as negative psychological effects on the parents. In 2011, after the civil war began in Syria, a great wave of immigration began to Turkey and other neighboring countries. Refugees may not be able to receive optimal health care because of cultural differences, socioeconomic status, language problems, and psychosocial problems. To increase awareness about this issue, the authors investigated the demographic, perioperative, and post-operative data of Syrian refugee patients with CL/P who were admitted to our cleft center between January 2016 and May 2019. Sixty-eight refugees with CL/P were detected as the result of the screening. Unlike the protocol the authors follow in our center, cleft lip repair was performed at an average of 7.6 months and cleft palate repair was performed at an average of 28.7 months of age. The rate of fistula was found 26.2%.The civil war in Syria has caused the repair of the patients with cleft lip and palate at a later age, hampered the follow-up and treatment, and caused more complications. Considering the demographic, social, economic and cultural characteristics of the patients, it was demonstrated that the necessary health precautions and infrastructure should be provided on the pillar of plastic surgery.

RESUMEN

Photobiomodulation (PBM) has emerged as a potentially effective therapeutic approach to modulate cellular functions. This study aimed to examine the impact of PBM on reactive oxygen species (ROS), lipid peroxidation, and glutathione-related antioxidant defense systems in rabbit eye tissues. A polychromatic light source with an intensity of 2.6 J/cm2/min was used for PBM treatment in New Zealand White rabbits for 12 min. The PBM group (n = 8) received treatments every 2 days for a total of 12 sessions, whereas the control group (n = 8) did not undergo any PBM light exposure during the same period. The application of PBM significantly elevated ROS-mediated glutathione levels, along with increased activities of glutathione peroxidase and reductase, particularly in corneal tissue (p ≤ 0.05). In conclusion, PBM treatment effectively enhances antioxidant defense mechanisms in the eye, particularly in corneal tissue, suggesting its potential as a therapeutic strategy for managing oxidative stress-related ocular conditions.

RESUMEN

The purpose of this study was to evaluate the speech outcomes, reveal postoperative rates of obstructive sleep apnea, and characterize changes in the pharyngeal flap and velopharyngeal anatomy following pharyngeal flap surgery for velopharyngeal insufficiency. A retrospective chart was reviewed for patients with clefts who underwent pharyngeal flap surgery between November 2020 and November 2021. The data collected included age, gender, cleft palate type, age at pharyngeal flap surgery, postoperative complications, age and type of primary palatoplasty, preoperative and postoperative speech assessments, magnetic resonance imaging findings, and obstructive sleep apnea outcomes. The authors included 72 nonsyndromic patients who underwent pharyngeal flap surgery following cleft palate repair. The mean age at pharyngeal flap surgery was 10.6 ± 6.2 years. There was a significant improvement in the Pittsburgh Weighted Speech Score Hypernasality Component and the nasalance scores of oral syllables (p < 0.001). The obstructive sleep apnea rate after pharyngeal flap surgery was 6.9%. Compared to preoperatively, the velar angle was more acute (p < 0.001), the velar length was longer (p < 0.001), the distance of the velum tip to the posterior pharyngeal wall was shorter (p < 0.001), the size of velopharyngeal gap was narrower (p < 0.001), and the pharyngeal flap atrophied (p < 0.001) at 6 months postoperatively. The pharyngeal flap improved speech outcomes in patients with velopharyngeal insufficiency with a relatively low incidence of obstructive sleep apnea (6.9%). The velum is positioned more superiorly and posteriorly, and the size of the velopharyngeal gap is substantially reduced after pharyngeal flap surgery. In addition, the pharyngeal flap partially atrophied over time.

RESUMEN

BACKGROUND: Capsular contracture is the most common complication following breast augmentation. Recently, prophylaxis studies aiming to inhibit the release of profibrotic substances to prevent capsular contracture have gained in importance. This study investigated the effects of cromolyn sodium, montelukast, and zafirlukast on capsular contracture in a rat model. METHODS: Thirty female Wistar albino rats were randomly divided into five groups: control, sham, cromolyn sodium, montelukast, and zafirlukast. Intraperitoneal injections were administered daily to the sham (1 ml per day), cromolyn sodium (10 mg/kg per day), montelukast (10 mg/kg per day), and zafirlukast (1.25 mg/kg per day) groups 1 month before surgery. Miniature breast implants were then placed on the backs of the rats in each group. Injections were continued for the next 3 months. The rats were subsequently killed, and the capsules were harvested and assessed histopathologically. The histopathologic outcomes were acute inflammation status, inflammation severity, synovial metaplasia, foreign body reaction, mast cell count, and capsular thickness. RESULTS: The cromolyn sodium, montelukast, and zafirlukast groups had less acute inflammation and lower mean inflammation severity scores, foreign body reaction occurrence, mast cell counts, and capsular thickness than the control and sham groups ( p < 0.05). These parameters were better in the cromolyn sodium group than in the montelukast and zafirlukast groups ( p < 0.05). CONCLUSIONS: Cromolyn sodium appears to inhibit capsular contracture more efficiently than montelukast and zafirlukast. This report may be a pioneer study for the prophylactic use of cromolyn sodium in capsular contracture. CLINICAL RELEVANCE STATEMENT: The prophylactic administration of cromolyn sodium appears to reduce capsular contracture more efficiently than that of montelukast and zafirlukast. This report might constitute a pioneer study for the prophylactic use of cromolyn sodium in capsular contracture.
