Can Clinical Findings Predict Orbital Fractures and Treatment Decisions in Patients With Orbital Trauma? Derivation of a Simple Clinical Model.

The aim of this study was to determine the predictive value of 4 clinical signs (periorbital ecchymosis, periorbital emphysema, diplopia, and inferior orbital nerve hypoesthesia) for the diagnosis of orbital fractures (OFs) and the need for surgical treatment in patients with orbital trauma. The investigators designed and implemented a retrospective cohort study composed of patients with orbital trauma. The primary and secondary outcomes were respectively the diagnosis of OFs and the need for surgical treatment. Multivariable logistic regressions including the clinical signs, age, and causes of injury were used to determine the independent contribution of each clinical sign to the prediction of the outcomes and to obtain weights to compute OF and surgery scores. The outcomes were assessed by receiver-operating characteristic (ROC) curves, sensitivity, specificity, and positive and negative predictive values. A total of 912 patients were included. All clinical signs except periorbital ecchymosis were significantly associated with OFs and the need for surgical treatment (P 0.7). Patients with an OF score >3 were likely to have an OF and patients with a surgery score

Levator Aponeurosis and Muller Muscle Plication Reinforced With Levator Sheath Advancement for Blepharoptosis Correction.

The authors innovated the levator aponeurosis and Muller muscle plication reinforced with levator sheath advancement (AMPSA) for blepharoptosis correction. The orbital septum was opened 1 mm above its fusion with the levator aponeurosis. The preaponeurotic fat was retracted and the thickened part of the levator sheath was identified. Two plication sutures were made: medial suture at the medial border of the pupil and lateral between the lateral border of the pupil and the lateral limbus. A needle with 6-0 nylon thread first bit the tarsal plate approximately 1 mm below its upper border, then bit the levator aponeurosis and the Muller muscle together at 3 to 6 mm above the upper border of the tarsal plate. The needle bit 1 to 3 mm of the thickened part of the levator sheath and the suture was tied. A total of 116 eyes were operated on using levator aponeurosis and Muller muscle plication (AMP), and 79 eyes using AMPSA. The mean follow-up period was 11.4 months. In the AMP group, the postoperative marginal reflex distance-1 (MRD-1) (3.8 +/- 0.2 mm) was significantly greater than the preoperative MRD-1 (2.7 +/- 0.3 mm) (P

Does Septoplasty Improve Heart Functions of Patients With Septum Deviation in Terms of Echocardiography Findings?.

Objective: The authors aimed to determine pulmonary artery pressure and right heart functions in patients with nasal septum deviation (NSD) with echocardiography (EchoCG) and compare the postoperative changes of EchoCG parameters with preoperative findings. Methods: Seventy-six patients who underwent septoplasty composed the study group. Average age of patients was 23.50 ranging between 18 and 48 years of age. There were 53 males (69.7%) and 23 females (30.3%). Mean pulmonary artery pressure, tricuspid annular-plane systolic excursion, right ventricular diameter, and e/a ratio were measured by EchoCG preoperatively and same parameters were reobtained 3 months after surgery. Results: Mean pulmonary artery pressure reduced from 23.88 +/- 6.36 to 19.80 +/-3.95 mm Hg and tricuspid annular-plane systolic excursion increased from 22.36 +/-3.85 to 23.57+/-3.00 3 months after surgery. It represented statistically significant improvement at right heart functions postoperatively (P

Craniofacial and Dental Features in Six Children With Cherubism.

Cherubism is an autosomal-dominant benign bone disorder, characterized by fibro-osseous lesions in the mandible and maxilla commonly caused by mutations in the SH3-binding protein 2-gene. The purpose of the authors' study was to analyze craniofacial and dental features of children diagnosed with cherubism, describe their treatment, and assess their dental age compared with norms for Finnish children. Six children were diagnosed, followed up and treated due to dental and skeletal disorders caused by cherubsim. The patients were followed up for an average of 91.5 months with emphasis on the skeletal changes and development of dentition. The treatment consisted of minor orthodontic treatment, dental extractions, and exposures. One patient underwent cosmetic mandibular surgery. All patients had lesions in the lower jaw and 5 of 6 patients had lesions in the maxilla as well. The patients were characterized by varying swelling of the jaws, premature loss of deciduous teeth in the affected area and widely spaced, displaced, un-erupted, or absent permanent teeth. The dental age was delayed at younger age but near to normal or even a little ahead at older age. Even though cherubism affects the jaws, jaw positions, and malocclusion, no common dentofacial proportions associated with the disease could be confirmed by cephalometric analysis. The surgical interventions did not provoke adverse reactions or local growth of the lesions. (C) 2017 by Mutaz B. Habal, MD.

Surgical Tip for Prevention of Lip Injury During Orthognathic and Facial Bone Contouring Surgery.

Iatrogenic lip injury is a rather common complication after facial bone surgery, but is usually treated lightly by the surgeon compared with other more severe functional complications. However, these injuries can have permanent sequelae and can therefore be a reason for patient dissatisfaction, especially after cosmetic surgery. Intraoperative lip injuries during facial bone surgery are usually caused by heat-generating surgical instruments or forced traction on the operative fields. The authors have applied a special technical strategy using a hydrocolloid dressing material to avoid these intraoperative lip injuries. This method does not disturb the operative procedure itself, but efficiently prevents lip injuries and decreases surgical morbidities and postoperative swelling. (C) 2017 by Mutaz B. Habal, MD.

Stability of Orbital Floor Fracture Fixation After Endoscope-Assisted Balloon Placement.

In recent years, endoscope-assisted balloon fixation using transantral and endonasal approaches has gained popularity as a minimally invasive treatment for orbital floor fractures. However, the optimal duration for balloon placement and the efficacy of the method have not been fully evaluated. The authors report their assessment of this method using postoperative and chronological measurements of the maxillary sinus volume. Fourteen patients with blowout fracture of the orbital floor who underwent reduction using endoscopic transantral and endonasal approaches followed by 6-week fixation with a balloon were evaluated. The volume of the maxillary sinus was measured for comparison using computed tomography at the time of balloon removal and 6 months after the surgery. The ratio of change in the maxillary sinus volume (maxillary sinus volume 6 months after surgery/maxillary sinus volume at balloon removal) for all subjects was 0.90 to 1.04 (0.96 +/- 0.44, mean +/- SD). No postoperative reduction in volume was detected, indicating satisfactory fixation. Postoperative computed tomography showed bone regeneration in the orbital floor in all patients in whom the fractured bone fragments were removed. No subjects had remaining enophthalmos greater than 2 mm. The postoperative change in the maxillary sinus volume was small, confirming the efficacy of 6-week balloon placement. This method was effective even in patients in whom fractured bone fragments were removed. Therefore, it is advisable to remove the fractured bone fragments if there is concern that the fragments will stray into the orbit due to inflation of the balloon. (C) 2017 by Mutaz B. Habal, MD.

Albuminuria in Pediatric Patients With Adenotonsillar Hypertrophy.

The relationship between intermittent nocturnal hypoxia and albuminuria in pediatric patients with adenotonsillar hypertrophy was evaluated in this prospective study. Fifty children with grade 3 to 4 adenotonsillar hypertrophy scheduled for adenoidectomy and/or adenotonsillectomy were selected for study group. Fifteen patients with adenotonsillar grade 1 to 2 or adenotonsillectomized subjects in a similar range of sex, age, and body mass index scheduled for other surgeries were selected for control group. All children were monitored using finger pulse oximeter during the night before surgery. At the day of surgery, first morning urine samples were sent to the laboratory for analysis of albuminuria. Albuminuria was determined in 8 (16%) patients in study group and 1 (6.7%) patient in control group. This difference between groups was determined not to be statistically significant (P > 0.05). None of the pulse oximetry parameters was also found to be associated with albuminuria statistically (P > 0.05). However, the adenoid grade was observed to be associated with albuminuria (P = 0.011). This study revealed no relationship between albuminuria and intermittent hypoxia in children, although previous studies have reported that intermittent hypoxia causes albuminuria in adults. On the contrary, the adenoid grade was found to be in association with albuminuria. The reason seems to be unclear because of the lack of studies investigating albuminuria in children with adenotonsillar hypertrophy. However, inflammatory mediators arising from adenoid tissue may cause increase in renal capillary permeability and urine albumin excretion. (C) 2017 by Mutaz B. Habal, MD.
