The 3D structure developed here can potentially be used for clinical application in CFM patients with absent or rudimentary TMJ for distraction and further avoidance of the need for tracheostomy for airway obstruction.The recurrence of chronic subdural hematoma (CSDH) is high post-treatment. In this study, we aimed to construct individualized models for prediction of the postoperative recurrence of CSDH in patients underwent twist-drill craniostomy combined with urokinase (UK) instillation. In total, 183 patients with CSDH were retrospectively enrolled. In summary, 21 candidate factors were retrieved from past medical records. The least absolute shrinkage and selection operator regression was adopted to reduce the high dimensionality of data. Four predictors preoperative hematoma volume, encephalatrophy, brain re-expansion, and UK instillation frequency were filtered from the 21 candidate factors using the least absolute shrinkage and selection operator method. Binary logistic regression model was employed to establish preoperative and postoperative prediction models. The preoperative model included preoperative hematoma volume and encephalatrophy whereas the postoperative model included brain re-expansion and UK instillation frequency. The predictive performance of the nomograms was evaluated by the receiver operating characteristic curve and calibration chart. Area under curve of the preoperative and postoperative models were 0.755 (95% confidence interval 0.690-0.889) and 0.782 (95% confidence interval 0.720-0.936), respectively, indicating good discrimination ability. The calibration results showed good fitting between the predicted probability and the actual probability. Finally, a decision curve analysis revealed excellent clinical performance of the proposed nomograms. Functionally, the preoperative model was used to identify high-risk patients with CSDH and application of UK, while the postoperative model was applied to guide physician-patients communication during follow-up. These 2 prediction models provide a basis for further clinical and experimental studies.
Maxillary osteotomy is typically undertaken to correct abnormal facial growth in cleft lip and palate. The surgery can cause velopharyngeal insufficiency resulting in hypernasality. This study aims to identify valid predictors of acquired velopharyngeal insufficiency following maxillary osteotomy by using a range of perceptual and instrumental speech investigations and multiple regression.

A prospective study was undertaken consisting of a consecutive series of patients with cleft lip and palate (N = 20) undergoing maxillary osteotomy by a single surgeon. Participants were seen at 0 to 3 months pre-surgery (T1), 3-months (T2), and 12-months (T3) post-surgery. Hypernasality was rated using the cleft audit protocol for speech-augmented (CAPS-A) and visual analog scales, and nasalance was measured on the Nasometer II 6400. For lateral videofluorosopic and nasendoscopic images, visual perceptual ratings and quantitative ratiometric measurements were undertaken. Multiple regression analyses were undertaken to identify predictors.

T3 models with hypernasality as the dependent variable were found to be a good fit and significant (eg, CAPS-A R2 = 0.920, F(11,7) = 7.303, P = 0.007). Closure ratio (a quantitative ratiometric measurement) and proportion of palate contacting the posterior pharyngeal wall (a visual perceptual rating) were identified as significant predictors for the CAPS-A model (P = 0.030, P = 0.002).

However, some patients encounter difficulties in oral function and limited mandibular movements. An objective evaluation has seldom featured actual kinetic measurements after mandibular reconstruction.Thirty patients who underwent mandibular reconstruction using bony free flap were enrolled in the study. Twenty-two patients were recruited after surgery and compared to a control group of 8 healthy subjects; 8 patients underwent both pre and postoperative evaluations. For each patient, a kinesiographic scan was obtained, recording maximum mouth opening, maximal laterality, and maximal protrusion.All postoperative kinesiographic evaluations were performed at least 6 months after surgery to ensure complete healing. In the first group of 22 patients, all measured movements were less than those of healthy controls, in particular maximum mouth opening. In the second study group (pre and postoperative evaluation), the postsurgical values did not achieve the control ones, but were no less than the preoperative values, granting adequate functional outcomes.The kinesiograph appears useful for objectively recording the functional outcomes in patients who have undergone mandibular reconstruction. The postoperative jaw movements were acceptable, ensuring a sufficient functional recovery.
The aim of this study was to evaluate both audiological and tinnitus related results in patients with tinnitus undergoing ossicular chain reconstruction (OCR) for ossicular chain injury.

Between January 2015 and January 2019, patients who underwent OCR due to ossicular chain pathology and developed tinnitus symptoms were included in the study group. Middle ear pathologies were standardized using the middle ear risk index (MERI) scoring system and the tinnitus handicap inventory (THI) was used to determine the severity of tinnitus. The surgical methods used for reconstruction were partial ossicular replacement prosthesis (PORP) or total ossicular replacement prosthesis (TORP), depending on the patient's pathology.

The study group consisted of 43 patients aged between 34 and 65 years. Mean MERI score of the patients was 6.42 ± 2.52. When assessed categorically, 18.6% of the study group was identified in the 'mild', 46.5% were in the 'moderate', and 34.5% were in the 'severe' MERI category. selleck kinase inhibitor Patients in the TORP group and those who were undergoing second session OCR had higher MERI and preop THI scores. Post-operative tinnitus levels were higher in patients who had OCR in the second session and were in the severe risk group. The ABG and tinnitus scores of patients were found to improve with OCR. In patients who underwent TORP, both ABG and tinnitus scores decreased significantly. Whereas, in patients who underwent PORP, only ABG values decreased significantly. After OCR, both ABG value and tinnitus scores significantly decreased compared to pre-operative results. ABG recovery rate was 100% in the study group.

It can be said that OCR positively changes both audiological parameters and tinnitus levels in ossicular chain pathologies.

To describe the osteoplastic approach and to perform a systematic review of the indications and outcomes of the osteoplastic flap procedure for frontal sinus surgeries with or without obliteration.

PubMed, Medline, Google Scholar, and Cochrane databases.

All published studies in the English language on the osteoplastic flap with or without obliteration were identified from 1905 to 2018. All studies with <20 patients were excluded. The number of patients, technique, indications, follow-up period, symptom relief, revision rates, and complications were recorded and analyzed.

A systematic review yielded 25 series containing 1374 patients for analysis. Indications for surgery included chronic frontal sinusitis, mucoceles, fractures or traumas, osteomas, neoplasms, and cerebrospinal fluid leak. The mean follow-up period ranged from 12.8 to 144 months. The percentage of patients needing revisions for frontal sinus disease was 6.2%. There was a high rate of symptomatic improvement (85.0%) and a low rate of of frontal sinus disease.Frontal sinus fractures require a large amount of force and often occur in the context of a major trauma. Many patients with these fractures are assessed in an emergent setting where stabilization takes precedence. Delayed diagnosis and treatment of a sinus fracture can result in life-threatening conditions, such as a cerebrospinal fluid (CSF) leak. A number of different treatment algorithms have been proposed, highlighting the complexity of frontal sinus fracture management. The goal of this study is to determine how patients with frontal sinus fractures were treated at Texas Tech University Health Sciences Center and what complications arose as a result of the fracture and subsequent management strategy. Over 9 years, there were 69 reported cases. A total of 63 of these occurred in males (91.3%) versus 6 (8.7%) in females. The majority occurred after a motor vehicle collision (MVC) or a motorcycle collision (MCC). A total of 51 cases were unilateral fractures and 18 were bilateral fractures. Five patients (7.2%) had CSF leakage and 64 (92.8%) did not have CSF leakage. One patient with CSF leakage (20.0%) was managed operatively. Of the 64 patients without CSF leakage, 4 (6.3%) were managed operatively. All operative patients were managed by cranialization. Complications included vision changes, facial pressure, anosmia, facial paresthesia, pneumocephalus, and mucus retention cysts. Vision changes were the most common complication. There did not appear to be any significant difference in complications between the CSF leakage groups, indicating that non-operative management remains a viable option in the management of frontal sinus fractures.
Velopharyngeal insufficiency (VPI) is a common problem after cleft palate repair that is often related to palatal shortening and insufficient levator reconstruction. For VPI correction in our cleft center, palatal re-repair with double-opposing Z-plasty is the standard operation.

To assess the efficacy of double-opposing Z-plasty in treatment of VPI after primary surgery for unilateral cleft lip and palate (UCLP).

This retrospective analysis comprised 109 consecutive UCLP patients born between 1997 and 2014 with VPI that required re-operation, and were operated on by 2 highvolume cleft surgeons, followed by perceptual and instrumental (Nasometer) evaluation of velopharyngeal competence (VPC).

Preoperatively, VPI was severe in 96% (105 of 109) and mild-to-moderate in 4% (4 of 109). Median age at surgery was 5.6 years (range 2.8-21.9). Postoperatively, 84% of patients achieved adequate VPC 65% (71 of 109) were competent and 19% (21 of 109) borderline competent. Postoperative adequate VPC was 89% (70 of 79) in nonsyndromic Finnish patients, 50% (4 of 8) in syndromic patients, and 82% (18 of 22) in adoption children. Compared to Finnish nonsyndromic patients, patients with syndrome had more residual VPI (P = 0.003), but no statistically significant difference existed for adoption patients (P = 0.251). Complications of the double-opposing Z-plasty included hemorrhage, postoperative mild airway obstruction, and wound-healing problems, each arising in 2 (1.8%) patients. Fourteen (13%) patients needed a second VPI operation.

Double-opposing Z-plasty seems to be a good and safe treatment option for VPI in patients with previously repaired UCLP with a success rate of 84%.
