ex P = 0.52, BA P = 0.41). Magnetic resonance imaging scores tended to be rated higher than the CT scores as age increased, although this difference was not statistically significant (P = 0.09). The higher the peripheral blood eosinophil percentage, the more the magnitude by which the CT score tended to exceed the MRI score; however, this finding was also not statistically significant (P = 0.11). Magnetic resonance imaging scans should be limited to the evaluation of intracranial regions. Scans of olfactory cleft and ethmoid cells are not accurate for the assessment of olfactory dysfunction.
Facial nerve injuries are a common complication associated with parotidectomy. These functionally debilitating injuries are conventionally treated with nonvascularized nerve grafting; however, this reconstructive modality produces moderate donor site morbidity and has limited efficacy for repairing large defects. In addition, nonvascularized nerve grafts are highly susceptible to radiotherapy and require a well-vascularized wound bed to produce adequate therapeutic results. The fascicular turnover flap, described by Koshima et al, utilizes a single fascicle to bridge two nerve endings that are in series with no donor site morbidity. Although studies have demonstrated this technique's efficacy, there is a paucity of data regarding its use in patients undergoing facial nerve reconstruction. Herein, we describe our early clinical experience using the fascicular turnover flap to reconstruct branches of the facial nerve in patients undergoing extensive parotidectomy. Our patients underwent successful reconstructhima et al, utilizes a single fascicle to bridge two nerve endings that are in series with no donor site morbidity. Although studies have demonstrated this technique's efficacy, there is a paucity of data regarding its use in patients undergoing facial nerve reconstruction. Herein, we describe our early clinical experience using the fascicular turnover flap to reconstruct branches of the facial nerve in patients undergoing extensive parotidectomy. Our patients underwent successful reconstruction of the nerve defects produced by parotidectomy using the fascicular turnover flap. Despite postoperative radiotherapy, both patients demonstrated complete functional recovery at six months postoperatively. Although formal head-to-head studies are needed to compare the outcomes of this technique versus conventional nerve grafting for facial nerve reconstruction, our preliminary experiences suggest that the fascicular turnover flap is a viable modality of reconstruction with great potential.
The purpose of this study was to analyze the clinical characteristics and treatment outcomes of patients who underwent endoscopic surgery for a maxillary sinus organized hematoma during a 15-year period in our hospital.

The authors analyzed 25 patients who underwent endoscopic surgery for a maxillary sinus organized hematoma from January 2004 to December 2019.

Twenty-five patients with a maxillary sinus organized hematoma underwent endoscopic surgical treatment and complete removal of the maxillary sinus organized hematoma was achieved in all cases. The main symptoms were nasal bleeding in 14 patients, followed by a nasal obstruction in nine, and facial swelling in 2. Of the 25 patients, 13 underwent endoscopic medial maxillectomy and 12 underwent endoscopic sinus surgery. There were no major surgical complications or recurrences.

The authors demonstrated that endoscopic surgery is a safe and reliable treatment method for a maxillary sinus organized hematoma.

Both dental agenesis and maxillary growth restriction are well-recognized sequelae in patients with unilateral cleft lip and palate, but their etiology remains controversial. The aim of this study was to evaluate the relationship between hypodontia and maxillary volume. A retrospective review of patients age 6 to 9 with Veau III (unilateral) cleft palate who underwent Cone Beam Computer Tomography in preparation for alveolar bone grafting at 2 major Children's Hospitals between 2010 and 2016 was conducted and serial panoramic radiographs were reviewed. Thirty-eight patients were identified that met inclusion criteria and had adequate imaging. Group 1 ("poor growers") consisted of the bottom 50% of Sella-Nasion-A point minus Sella-Nasion-B point (ANB) angles and Group 2 ("good growers") consisted of the top 50% of ANB angles. PHA-767491 ic50 Group 1 had a significantly higher mean number of missing teeth (1.58 ± 0.28 missing teeth) compared to Group 2 (0.74 ± 0.23 missing teeth), and significantly lower maxillary volume (1250% of Sella-Nasion-A point minus Sella-Nasion-B point (ANB) angles and Group 2 ("good growers") consisted of the top 50% of ANB angles. Group 1 had a significantly higher mean number of missing teeth (1.58 ± 0.28 missing teeth) compared to Group 2 (0.74 ± 0.23 missing teeth), and significantly lower maxillary volume (12.88 ± 0.61 cm3 versus 15.24 ± 0.88 cm3, respectively). The severity of maxillary hypoplasia in cleft patients increases with increased dental agenesis. These data indicate that intrinsic factors play a significant role in maxillary growth restriction in cleft patients, independent of the sequelae of surgical intervention.
The purpose of this study is to propose a surgical plan based on augmented reality (AR) and guide template technology for restoration of nasal deformities, and evaluate its feasibility and clinical efficacy.

Patients were scanned with a FaceScan to obtain the three-dimensional (3D) facial model, and computed tomography was also performed to obtain the maxillofacial computed tomography images while wearing the artificial marker. The mirroring tool and database searching and matching technology were employed to restore the nasal deformities for a normal nose (preoperative planning model). The design of guide template for deciding the incision area was based on the preoperative planning model, which was also imported into the AR image guidance system named HuaxiAR1.0 for reconstruction of the nose contour. One week after the surgery, the postoperative 3D facial model was obtained. Then, the clinical efficacy was evaluated by comparing the difference between the preoperative planning and postoperative 3D facial model.
