Object The objective of this study was to investigate the clinical characteristics, intraoperative findings, complications, and outcomes after the first microvascular decompression (MVD) in patients with and without previous botulinum neurotoxin treatment for hemifacial spasm (HFS). Methods The authors analyzed 246 MVDs performed at the University of Pittsburgh Medical Center between January 1, 2000, and December 31, 2007. One hundred and seventy-six patients with HFS underwent botulinum neurotoxin injection treatment prior to first MVD (Group I), and 70 patients underwent their first MVD without previous botulinum neurotoxin treatment (Group II). Clinical outcome data were obtained immediately after the operation, at discharge, and at follow-up. Follow-up data were collected from 177 patients with a minimum follow-up period of 9 months (mean 54.48 ± 27.84 months). Results In 246 patients, 89.4% experienced immediate postoperative relief of spasm, 91.1% experienced relief at discharge, and 92.7% experienced relief at follow-up. There was no significant difference in outcomes and complications between Group I and Group II (p > 0.05). Preoperatively, patients in Group I had higher rates of facial weakness, tinnitus, tonus, and platysmal involvement as compared with Group II (p < 0.05). The posterior inferior cerebellar artery and vertebral artery were intraoperatively identified as the offending vessels in cases of vasculature compression in a significantly greater number of patients in Group II compared with Group I (p = 0.008 and p = 0.005, respectively, for each vessel). The lateral spread response (LSR) disappeared in 60.48% of the patients in Group I as compared with 74.19% in Group II (p > 0.05). No significant differences in complications were noted between the 2 groups. Conclusions Microvascular decompression is an effective and safe procedure for patients with HFS previously treated using botulinum neurotoxin. Intraoperative monitoring with LSR is an effective tool for evaluating adequate decompression.

Object The authors conducted a large retrospective study in which they evaluated the efficacy of intraoperative electromyography (EMG) monitoring of facial musculature during microvascular decompression (MVD) and assessed the predictive value of the lateral spread response (LSR) as a prognostic indicator for the treatment outcome of hemifacial spasm (HFS). Methods The authors undertook intraoperative monitoring during MVD in 300 consecutive patients with HFS. The patients were divided into two groups based on whether the LSR disappeared or persisted following decompression. The mean follow-up period was 35.8 months (range 12–55 months). In 263 (87.7%) of the 300 patients, the LSR was observed during intraoperative facial EMG monitoring. In 230 (87.4%) of these 263 patients, the LSR disappeared following decompression (Group I), and in the remaining 33 patients (12.5%) the LSR persisted despite decompression (Group II). At the postoperative 1-year follow-up visit, there was a significant difference in clinical outcomes between both groups (p < 0.05). Conclusions Facial EMG monitoring of the LSR is an effective tool to use when performing complete decompression, and it may be helpful in predicting outcomes.

Abstract Objective: Microvascular decompression, although a well-established procedure for treating primary trigeminal neuralgia, still has no standardized protocol. The practical consequences of having the implant keep the conflicting vessels apart, whether or not in contact with the root, is still in debate. The present work was undertaken to answer this question. Methods: Patients were segregated into 2 groups: Group I (260 patients) had a Teflon prosthesis implanted without contact to the root, and Group II (70 patients) had a similar implant with contact to the root. Cure rates in the 2 groups were compared at the latest follow-up (≤15 yr; average, 8.2 yr) using Kaplan-Meier analysis. Results: In Group I, the cure rate was 82% (214 of 260 patients), whereas in Group II, the cure rate was 67% (47 of 70 patients) (P = 0.01). Kaplan-Meier analysis of the follow-up period up to 15 years also shows a significant difference (P = 0.05). Conclusion: These results strongly support the goal of performing the procedure without the implant in contact with the root. This is easier with the superior cerebellar artery, because of its laxity and small number of perforating branches, than with the anteroinferior cerebellar artery, which has perforators to the brainstem and labyrinthine artery arising from its cisternal portion. The significantly better long-term cure rate when the implant is not in contact with the root favors the “pure” decompressive effect of the microvascular decompression procedure, rather than a conduction block mechanism.

Surgical Failure

Past experience with open and closed techniques of tympanoplasty in surgery of cholesteatoma has shown that recurring illness is one of the major causes of surgical failure. The literature has reported varying trend of surgical treatment of cholesteatoma. The objective of the study was to analyze the significance of surgical technique in relation to the incidence and most frequent localization of recurrent cholesteatoma. Our study analyzed 120 patients operated on for cholesteatoma. The patients were divided into two groups, group I (45) with recurring disease and group II (75) without any recurring condition, which were followed up three years. Statistical analysis was carried out by modified t-test. The largest number of patients was re-operated in the first two years from the initial surgery (50%), In the majority of patients (50%), recurrent cholesteatoma was most commonly localized (stage I) in attic (20%) and much rarely in mesotympanum (11,9%). Stage III recurrent cholesteatoma was verified in 35% of patients, most frequently diffuse form (13,4%). The involvement of attic by all three stages of disease accounted for over 60%. The analysis of the used techniques of surgical treatment in both groups revealed significant difference. Open techniques of tympanoplasty were used in 60% of patients with no recurrence. Closed techniques were used more frequently in patients with recurring disease, i.e. in over 90% of cases. Recurrent cholesteatoma develops, in the majority of cases, during the first two years after the surgical intervention. Attic is the most common localization of cholesteatoma. More frequent utilization of open technique of tympanoplasty for surgery of cholesteatoma significantly reduces the incidence of recurring condition. The indications for CWD technique are the initial spread of cholesteatoma, possibility of complete removal of cholesteatoma and postoperative follow-up of patients.

PURPOSE: This study aimed to compare patients’ satisfaction with mandibular overdentures retained by three-splinted implants versus conventional complete denture wearers during a 7-year follow-up study period. MATERIALS AND METHODS: Thirty edentulous male patients (mean age: 60 years) were carefully selected and divided into two equal groups. All patients received a new set of complete dentures. Group I patients received three implants in the anterior mandible and were connected after 3 months with bars, clips, and loaded. Group II patients received conventional complete dentures. Patients’ satisfaction was recorded for both groups at 3 weeks (baseline) and after 1, 3, 5, and 7 years. Patients were then asked to grade their overdentures/dentures on a visual analog scale and written questionnaire to evaluate their overall satisfaction. RESULTS: Satisfaction scores of Group I patients were found to be statistically significantly higher than that of Group II patients (p < 0.05) at 3, 5, and 7 years follow-up, meanwhile, no statistically significant difference was found at baseline or after 12 months. CONCLUSION: The long-term results suggest that three-implant-retained mandibular overdenture with a clip-bar attachment appears to be a successful rehabilitation strategy which is superior to conventional dentures for patients with advanced ridge resorption.

Objectives (1) To conduct an adequately powered randomized controlled trial investigating the safety and efficacy of mitomycin C–enhanced revision endoscopic dacryocystorhinostomy (DCR) and (2) to analyze causes of failure after primary endoscopic DCR. Study Design A randomized controlled study. Setting General hospital. Subjects and Methods Seventy-six revision endoscopic DCRs were randomized into 2 groups: endoscopic DCR with mitomycin (group I), where 0.5 mg/mL mitomycin C was applied for 10 minutes, and endoscopic DCR without mitomycin (group II). Follow-up settings were done to document the patient’s subjective improvement, to judge ostium patency on irrigation, and to record any complications. Results Causes of failure in the original 92 patients included canalicular obstruction (14%), small misplaced bony window (43%), very small nasolacrimal stoma due to development of synechia (23%), and complete closure of nasolacrimal stoma with tough fibrous tissue (63%). There was no significant difference between the 2 groups in subjective and objective success rates and adverse events. Group I demonstrated a significantly longer operative time and a significantly lower number of debridement sessions (mean of 1.2 vs 1.9). Conclusions Recurrent nasolacrimal duct obstruction after primary endoscopic DCR is mainly due to reclosure of the nasolacrimal stoma with synechia and fashioning of the small misplaced bony window. Mitomycin C does not increase the success rate of revision endoscopic DCR. It is a safe procedure and may be of value only in patients inaccessible to strict follow-up because it induces a better healing profile in terms of mucosal recovery, wound healing, and less need for debridement sessions.

To assess proarrythmogenic effects after different techniques of radiofrequency catheter ablation, 427 patients with paroxysmal, persistent, and long-standing persistent atrial fibrillation (AF) were examined. The patients were randomized into four groups: antral pulmonary vein isolation (PVI) (Group I), PVI plus roof line and mitral isthmus ablation (Group II), anatomic ablation of ganglionated plexuses (GP) of the left atrium (Group III) and GP plus PVI (Group IV). At the end of follow up (34,43,2 months) the largest number of proarrythmogenic effects was observed in Group II, 24,8% (26 patients). In the remaining groups the percentage of proarrythmogenic effects did not exceed 11%, neither was there any significant difference among Groups I, III and IV. Thus, the creation of additional linear lesions in the left atrium is a predictor of proarrythmogenic effects during follow up.

Abstract Objective: To evaluate effectiveness and safety of a 5mg tadalafil daily treatment for men with erectile dysfunction (ED) and premature ejaculation (PE) and assessment of long-term follow up by persistence of improvement 2 years after stoppage of tadalafil.Materials and Methods: The study included 160 patients diagnosed with erectile dysfunction from April 2018 to June 2020. All were evaluated using the international index of erectile function questionnaire-5 (IIEF-5) to evaluate ED and intravaginal ejaculatory latency time (IELT) for PE. Patients subdivided into two equal groups. I included 80 patients treated with tadalafil 5 mg daily for 3 months, and group II included 80 patients treated with a placebo for same period. After 3 months treatment and 2 years later after stoppage of tadalafil, all patients were assessed for ED and PE using the same questionnaires. Results: The mean IELT and IIEF pretreatment were 37±11.24 s and 13.2±4.2 respectively for group I, while in group II was 35.98±10.8 s and 13.12±4.11, respectively. After 3 months of treatment, the mean value of IELT in group I showed a highly significant improvement from 37±11.24 sec to 120.5±47.37 sec (p-value < 0.001), but for group II, the mean values of IELT showed no significant improvement from baseline 35.98±10.8 to endpoint 39.43±13.6 ( p-value > 0.05). As regarding the IIEF, there was a highly significant improvement from baseline 13.2±4.2 to endpoint 20.45±4.5 in group I (p-value < 0.001) while there was no significant difference in group II from baseline 13.12±4.11 to endpoint 15±4.84 (p-value > 0.05) . 2 years later after stoppage of tadalafil , 75 patients from group I complete follow up and there was significant improvement in IELT and IIEF form base line (37±11.24) (13.2±4.2) to endpoint (98±18.3) (19.1±2.3) respectively but less than the results after 3 months treatment.ConclusionDaily Tadalafil 5 mg was effective, tolerable, and safe treatment for patients suffering from ED and PE. Long-term follow up after 2 years declared persistence of significant improvement.

Aims and Objectives: The purpose of this study was to evaluate the knee stability and subjective outcome after primary ACL reconstruction using either autologous semitendinosus or quadriceps tendon. Materials and Methods: We evaluated a total of 50 patients who underwent ACL reconstruction - including 25 using the ipsilateral semitendinosus tendon (group I) and 25 patients with autologous quadriceps tendon graft (group II). The follow-up of this prospective comparative study was at least two years after surgery, comprising clinical assessment according to the International Documantation Committee (IKDC), KT1000 arthrometer testing and an additional questionnaire including the Knee Injury Osteoarthritis Outcome Score (KOOS) and the Lysholm score. Results: The mean postoperative side-to-side difference assessed by KT1000 arthrometer was 1.8mm for group I and 1.7mm for group II with no statistically significant difference. There was no statistically significant difference neither in the individual KOOS subscores nor the Lysholm score. No re-rupture or positive pivot-shift test occurred during follow-up for both groups. Conclusion: Semitendinosus- as well as quadriceps tendon are both equal regarding their clinical outcome. Thus, the quadriceps tendon may serve as a good alternative graft for primary ACL reconstruction.
