“…Correlating allergic rhinitis cases with nasal sinus ultrasound could be a future step in the management of this pathology (13). Thus, we hope that our data will help shift the use of sonography from experimental to clinical practice in ENT and other allied specialties, such as ophthalmology, plastic surgery, and trauma surgery (14,15).…”

There is an increasing incidence of sinusitis cases in outpatient clinics; therefore, new methods for screening and triage are required. Performance of sinus sonography in our outpatient protocol was assessed in order to ascertain the specificity and sensitivity of this imaging method to detect rhinosinusitis. A total of 81 consecutive cases with clinical signs of sinusitis were collected and clinical data compared with sinus sonography results. Moreover, sinus sonography enhanced referral for further computed tomography scans. The results showed that sonography may be a screening method in sinus pathology, with a high sensitivity of 78.3% and a specificity of 93.1%. In the context of the COVID-19 pandemic, the use of ultrasound for paranasal sinus imaging should be reconsidered as in the case of lung sonography. According to data of the present study, sinus ultrasound may be implemented in the emergency departments with no access to standard ENT services and it could be efficient in managing sinusitis in pregnant women and pediatric cases.

“…[ 10 ] Fibrovascularization is of great importance for the long-term stability of HA implants. [ 11 ] Once the HA implant is completely vascularized, its stability will be further enhanced, and it cannot be easily exposed, extruded or infected. Vascularization of the HA implant is promoted in our improved surgical style largely because the posterior HA implant was directly exposed to the orbit, and thus, the postoperative complications were obviously reduced.…”

The effects of hydroxyapatite implantation with the autogenous sclera cap: A cohort study

et al. 2022

We performed a novel hydroxyapatite (HA) prosthesis implantation method in which an HA implant was implanted into the scleral shell with an autogenous scleral cap.Twenty-six patients who had undergone the novel HA prosthesis implantation method and 32 patients who had undergone traditional HA prosthesis implantation were retrospectively reviewed. The postoperative activity of the artificial eye was measured by the Hirschberg test combined with arc perimetry. The visual analog score (VAS) was used to evaluate 2-month postoperative pain and 2-month postoperative discomfort. HA implant vascularization was measured with enhanced magnetic resonance imaging (MRI) 2 and 6 months after the operation. The enhancement volume (V E ) and the volume of the HA implant (V HA ) were measured. All cases were followed up for 2 years. Measurement data were processed using SAS 6.12.There was a statistically significant difference (P = .016) between the percentages of excellent grade in the two groups. Two months after implantation, the median pain scores of the study and control groups were 2 and 2.5, respectively, and there was a statistically significant difference (W = 585.0, P = .004); there was a statistically significant difference (W = 535.5, P = .000) between the median discomfort scores of the study group (score = 1) and control group (score = 2); the mean VE/VHA values of the study and control groups were 0.3075 and 0.1535, respectively, and there was a statistically significant difference (t = −8.196, P = .000). Six months after implantation, the V E /V HA values of the study and control groups were 0.9686 and 0.5934, respectively, and there was a statistically significant difference (W = 549.0, P = .000). Within 2 years of postoperative follow-up, there were no serious complications in the study group.In the study group, in which the hydroxyapatite implant was implanted into a preserved scleral shell with unaltered muscles and covered with an autogenous scleral cap, postoperative activity and the fibrovascularization of the HA implant were significantly increased, and postoperative pain and discomfort were significantly reduced.
