RESUMO
INTRODUCTION: The connection between periodontitis and mild cognitive impairment (MCI) continues to receive attention. However, whether periodontitis is a risk factor for MCI remains still uncertain. This study aims to systematically analyze the available literature regarding the relationship between periodontitis and the risk of developing MCI and whether the periodontal health of MCI patients is poorer. METHODS: A literature search of PubMed, Scopus, Embase, and Web of Science databases was conducted to include all studies on the relationship between periodontitis and MCI from inception to April 2023. The studies were independently screened by 2 researchers, and those meeting the inclusion criteria were extracted and cross-checked. Pooled odds ratio (OR) or mean difference (MD) with 95% confidence intervals (CI) was calculated using either a fixed-effects or random-effects model. RESULTS: Seven studies with a total of 3,973 participants were included. Meta-analysis results showed a statistically significant higher incidence of MCI in patients with periodontitis (OR, 1.70 (95% CI: 1.24-2.32, p < 0.001) compared to healthy participants. A subgroup meta-analysis showed that the pooled OR for the risk of MCI in patients with severe periodontitis was 2.09 (95% CI: 1.49-2.92, p < 0.001). In addition, attachment loss (MD = 0.44, 95% CI: 0.12-0.75, p < 0.001) and plaque index (MD = 0.72, 95% CI: 0.50-0.93, p < 0.001) were higher in MCI patients compared with the control group, but the pocket probing depth (MD = 0.21, 95% CI: -0.08 to 0.49, p = 0.15) was not significantly different between the two groups. CONCLUSIONS: Patients with periodontitis are at a higher risk of developing MCI, and the periodontal health of MCI patients is generally compromised. However, further well-designed studies should be conducted to confirm this relationship between MCI and periodontitis.

OBJECTIVE: Radial Forearm Free flap (RFFF) is widely used in head and neck reconstruction, yet its donor site defect remains a significant drawback. The Medial Sural Artery Perforator Free Flap (MSAPFF) is considered an alternative flap to RFFF. This study aims to comprehensively analyze their characteristics, outcomes, and their impact on patient quality of life. METHODS: All patients who underwent oral cavity reconstruction using RFFF and MSAPFF between February 2017 and April 2023 were included in this study. Flap characteristics, outcomes and post-operative complications were recorded and compared. Subjective donor site morbidity, aesthetic and functional results, and quality of life were also analyzed. RESULTS: The study included 76 patients: 37 underwent reconstruction with RFFF, and 39 with MSAPFF. There was no significance difference between the RFFF and MSAPFF regarding the success rate (97.2% vs 97.4%), flap size (4.8 × 8.8 cm2 vs 5 × 9.8 cm2), hospital of stay (15.5 days vs 13.5 days) and recipient site complications (P > 0.05). However, MSAPFF showed larger flap thickness (P = 0.001), smaller arterial caliber (P = 0.008), shorter pedicle length (P = 0.001), and longer harvesting time (P < 0.001). No significant difference was observed between the pre-and postoperative ranges of wrist and ankle movements or in recipient site complications. MSAPFF showed a significant difference in donor site morbidity (P < 0.05). CONCLUSION: The MSAPFF is an excellent alternative to the RFFF for repairing oral cavity defects, with additional advantage of a well-hidden scar on the posterior calf, a larger flap thickness, accepted pedicle length and arterial caliber. However, one should consider the harvesting time and surgical skills required in comparison to the RFFF. CLINICAL RELEVANCE: The study highlights the importance of the MSAPFF as an alternative option for RFFF with less donor site morbidity and high success rate in oral cavity reconstruction and improved patient Quality of life after ablative surgery.

BACKGROUND: The present network meta-analysis aims to answer the question "what is the best topical intervention for the treatment of recurrent aphthous stomatitis that can provide an acceptable pain relief and promote wound healing?" METHODS: From inception to October 2022, PubMed, Embase, Scopus, Cochrane Library, and China National Knowledge Infrastructure were searched to identify all potentially eligible randomized controlled trials. The primary outcomes were pain scores and/or healing time, while the secondary outcomes were the associated side effects. The Bayesian network meta-analysis accompanied by a random effect model and 95% credible intervals were calculated. RESULTS: Forty-three randomized controlled trials with a total of 3067 participants, comparing 20 different topical medications, were included. Concerning pain reduction, the network meta-analysis failed to show any statistically significant differences when different topical treatments were compared together or even with a placebo at different time intervals. Except for doxycycline, which showed a statistically significant difference in terms of accelerating healing time, other topical interventions showed no statistically significant differences when compared with placebo or with each other. CONCLUSION: Within the limitations of the current network meta-analysis, it seems that: A low to moderate quality of evidence showed no superiority of any topical treatment over others concerning pain reduction, although rank probability tests revealed sucralfate, doxycycline, hyaluronic acid, and chamomile as the most efficacious treatment options at different evaluation times. Hence, further well-designed clinical trials with larger sample sizes are warranted. Topical doxycycline was shown to be the most efficacious intervention in promoting healing of recurrent aphthous stomatitis.

OBJECTIVES: To evaluate the effect of platelet-rich fibrin alone or in combination with different biomaterials for the treatment of periodontal intra-bony defect. METHODS: Up to April 2022, Cochrane library, Medline, EMBASE, and Web of Science databases were searched for randomized clinical trials. The outcomes of interest were probing pocket depth reduction, clinical attachment level gain, bone gain, and bone defect depth reduction. Bayesian network meta-analysis with 95% credible intervals was calculated. RESULTS: Thirty-eight studies with 1157 participants were included. Platelet-rich fibrin alone or platelet-rich fibrin +biomaterials showed a statistically significant difference when compared with open flap debridement (p < 0.05, low to high certainty evidence). Neither biomaterials alone nor platelet-rich fibrin +biomaterials showed a statistically significant difference when compared to platelet-rich fibrin alone (p > 0.05, very low to high certainty evidence). Platelet-rich fibrin +biomaterials showed insignificant differences as compared to biomaterials alone (p > 0.05, very low to high certainty evidence). Allograft +collagen membrane ranked the best in probing pocket depth reduction while platelet-rich fibrin +hydroxyapatite ranked the best in bone gain. CONCLUSION: It seems that (1) platelet-rich fibrin with/without biomaterials were more effective than open flap debridement. (2) Platelet-rich fibrin alone provides a comparable effect to biomaterials alone and platelet-rich fibrin +biomaterials. (3) Platelet-rich fibrin +biomaterials provide a comparable effect to biomaterials alone. Although allograft +collagen membrane and platelet-rich fibrin +hydroxyapatite ranked the best in terms of probing pocket depth reduction and bone gain respectively, the difference between different regenerative therapies remains insignificant, and therefore, further studies are still needed to confirm these results.

BACKGROUND: This study aimed to investigate the effect of vertical facial patterns on the developmental relationship between the nasal bone and maxillary central incisors. METHODS: In this retrospective comparative study, the lateral cephalograms of 213 subjects (51 Males, 162 Females) with skeletal Class I malocclusion (aged 18-32 years) were classified into three equal groups: (1) hyperdivergent, (2) normodivergent, and (3) hypodivergent facial patterns based on the mandibular plane inclination (S-N/Go-Me). Several sets of measurements were extracted: (1) gradient and length of the nasal bone and maxillary central incisor, (2) the distance from apex and root of the nasal bone, and (3) maxillary central incisor to the true perpendicular from the digitized lateral cephalograms. The significance level was considered at P < 0.05. RESULTS: The inclination angle and length between nasal bone and maxillary central incisor were positively correlated independent of vertical facial type. The inclination angle of the nasal bone in the hypodivergent group was significantly larger than the other two vertical facial patterns. The inclination angle of the maxillary central incisor increased successively in the hyperdivergent, normodivergent, and hypodivergent groups. The length of the nasal bone in the hyperdivergent group was significantly longer than that in the hypodivergent and normodivergent groups. The maxillary central incisor length in the hyperdivergent group was significantly longer than in the hypodivergent group. CONCLUSION: A correlation between nasal bone and maxillary central incisors during the growth and development of the maxillofacial region was found. In Class I malocclusion subjects, hypodivergent patients were more likely to have a prominent and relatively short nasal bone and maxillary central incisors and vice versa.

BACKGROUND: The trend in postoperative care for free flap patients is to deescalate from routine ICU admission into a specialty recovery unit. This study aims to investigate the predictive parameters in a routine perioperative clinical assessment that are expected to be directly correlated with prolonged ICU length of stay in at-risk patients who received oral reconstructive surgery for squamous cell carcinoma (OSCC). METHODS: All patients who underwent ablative surgery for OSCC with free flap reconstruction and were managed in the ICU were included in this study. The primary outcome was ICU-length of stay. Perioperative, operative and postoperative parameters were analyzed using single test ( t-test, ANOVA analysis, correlation coefficients, effect size) and multivariate regression test. The P-value was set as < 0.005 to be considered statically significant. RESULTS: The study included 136 homogeneous patients, with a mean ICU length of stay of 4.5 (± 4.43 day). Patients with pre-operative positive renal dysfunction (P = 0.004), peripheral vascular disease (P < 0.001), postoperative complications (P = 0.028) or positive heart failure class III (P < 0.001 ) were recognized as at-risk patients for a significantly longer ICU length of stay. CONCLUSION: Patients with perioperative severe renal dysfunction, peripheral vascular disease, postoperative complication or high NYHA class are prone to have a significantly longer ICU length of stay. Several factors were considered as confounders contributing to increased ICU management time in combination with other variables. Additionally, in highly risk patient, the presence of the highly trained medical support, including the appropriate nursing care, is more critical than those patients without these risk factors.

OBJECTIVE: To assess the maxillofacial growth of patients with isolated cleft palate following the Sommerlad-Furlow modified technique and compare it with the effect of the Sommerlad technique. STUDY DESIGN: A Retrospective Cohort Study. METHODS: A total of 90 participants, 60 patients with non-syndromic isolated soft and hard cleft palate (ISHCP) underwent primary palatoplasty without relaxing incision (30 patients received the Sommerlad-Furlow modified (S-F) technique and 30 received Sommerlad (S) technique). While the other 30 were healthy noncleft participants with skeletal class I pattern (C group). All participants had lateral cephalometric radiographs at least 5 years old age. All the study variables were measured by using stable landmarks, including 11 linear and 9 angular variants. RESULTS: The means age at collection of cephalograms were 6.03 ± 0.80 (5-7 yrs) in the S group, 5.96 ± 0.76 (5-7 yrs) in the S-F group, and 5.91 ± 0.87 (5-7 yrs) in the C group. Regarding cranial base, the results showed that there were no statistically significant differences between the three groups in S-N and S-N-Ba. The S group had a significantly shortest S-Ba than the S-F & C groups (P = 0.01), but there was no statistically significant difference between S-F and C groups (P = 0.80). Regarding skeletal maxillary growth, the S group had significantly shorter Co-A, S- PM and significantly less SNA angle than the C group (P = < 0.01). While there was no significant difference between S-F & C groups (P = 0.42). The S group had significantly more MP-SN inclination than the C group (P = < 0.01). Regarding skeletal mandibular growth, there were no statistically significant differences in all linear and angular mandibular measurements between the three groups, except Co-Gn of the S group had a significantly shorter length than the C group (P = 0.05). Regarding intermaxillary relation, the S-F group had no significant differences in Co-Gn-Co-A and ANB as compared with the C group. The S group had significantly less ANB angle than S-F & C groups (P = 0.01 & P = < 0.01). In addition, there were no significant differences in all angular occlusal measurements between the three groups. CONCLUSION: As a preliminary report, Sommerlad-Furlow modified technique showed that maxillary positioning in the face tended to be better, and the intermaxillary relationship was more satisfactory than that in Sommerlad technique when compared them in healthy noncleft participants.

STATEMENT OF PROBLEM: A systematic review of the effect of different overdenture attachments with different loading protocols on peri-implant health is lacking. PURPOSE: The purpose of this systematic review and network meta-analysis was to evaluate the effect of different overdenture attachments with delayed or immediately loaded 2-implant-retained mandibular overdentures on peri-implant tissue health. MATERIAL AND METHODS: A comprehensive search of the PubMed, EMBASE, and Cochrane library was conducted to identify eligible randomized controlled trials (RCTs). The outcomes were marginal bone loss, probing depth, plaque index, bleeding on probing, implant survival rate, and prosthetic complications. The Bayesian network meta-analysis accompanied by a random effect model and 95% credible intervals was calculated. RESULTS: Sixteen RCT (n=599 participants receiving 1198 dental implants) were included. Five common overdenture attachment systems with delayed or immediate loading were compared. The difference in marginal bone loss and probing depth was not statistically significant when comparing different overdenture attachments with different loading protocols. The rank probability test showed that bar+ immediate loading ranked highest (63.8%) in terms of marginal bone loss, whereas ball+ delayed loading (73.3%) ranked highest in terms of probing depth. The implant survival rate was 100% for the LOCATOR+ delayed loading, resilient telescopic+ delayed loading, and magnet+ immediate loading; however, bar+ delayed loading, ball+ delayed loading, magnet+ delayed loading, LOCATOR+ immediate loading, ball+ immediate loading, and bar+ immediate loading had survival rates of 99.1%, 98.8%, 96.0%, 94.7%, 93.1%, and 91.2%, respectively. CONCLUSIONS: All types of overdenture attachment with immediate loading or delayed loading had a similar effect on peri-implant health. Bar+ immediate loading was associated with the least marginal bone loss, whereas ball+ delayed loading showed the least probing depth.

A Schneiderian membrane (SM) thickness of >2 mm is regarded as a pathological mucosal change. The current study aimed to determine whether sinus floor elevation (SFE) in the presence of SM pathology increases the risk of membrane perforation and implant failure rate. MEDLINE, Embase, Cochrane Library, and CNKI, Wanfang, and VIP databases were systemically searched for studies published until February 2020. Randomized and nonrandomized studies reporting the incidence of SM perforation in patients with SM pathology (antral pseudocyst or mucosal thickening) during SFE were included. The outcome measures were the incidence of SM perforation and implant survival rate. The pooled odds ratio (OR) and 95% confidence intervals (CIs) were calculated using fixed-effects model. A P value ≤.05 was considered to be statistically significant. Eighteen studies with a total of 1542 patients and 1797 SFE were included. A nonsignificant difference in the incidence of SM perforation was observed between the normal-appearing sinus and thickened sinus mucosa (fixed effects; OR, 0.896; 95% CI, 0.504-1.59; P = .707, I2 = 32%). The rates of SM perforation in the normal sinus, mucosal thickening, and antral pseudocysts were 14%, 6%, and 6% respectively. The implant survival rate was 98% in the normal sinus and 100% in antral pseudocyst and mucosal thickening. SM thickening or antral pseudocysts did not increase the risk of membrane perforation or rate of implant failure. Additional randomized controlled trials are needed to evaluate the effect of pathological changes in the SM on the failure of bone augmentation and dental implants.

PURPOSE: To evaluate: 1) the efficacy of acellular dermal matrix (ADM) to prevent Frey's syndrome (FS) after superficial parotidectomy of benign tumors. 2) the effect of different follow-up intervals on the incidence of FS. METHODS: Fifty-five patients with benign parotid gland tumors underwent superficial parotidectomy were divided into two groups: Non-ADM group (n = 31, 56.3%) and ADM group (n = 24, 43.6%). The primary outcomes measure was the incidence of FS. The secondary outcomes were surgical site depression, infection, salivary sialocele, and salivary fistula. Subjective FS was evaluated using a clinical questionnaire submitted via WeChat at 3, 6, 12, 18, 24, and 32 months postoperatively. Objective FS was evaluated using Minor starch-iodine test at 6 and 12 months postoperatively. RESULTS: There was a statistically significant difference in the incidence of subjective and objective FS when ADM compared with Non-ADM groups (P<0.05). The respective incidence of subjective FS at 3, 6, 12, 18, 24, and 32 months was 4.2%, 8.3%,20.8%, 20.8%, 20.8%, 20.8% in ADM group and 3.2%, 9.7%, 29%, 38.7%, 45.2% in Non-ADM group. The incidence of objective FS after 6 and 12 months was 4.2%, 8.3% in ADM group and 8.3% (2/24), 38.7% (12/31) in Non-ADM group respectively. Five patients in ADM group and 1 patient in Non-ADM group developed sialocele, and all patients resolved with conservative management. Surgical site depression was significantly higher in the Non-ADM group (15/31) compared with (5/24) in ADM (P=0.049). No cases of immune rejection, infection, hematoma, or salivary fistula were observed in ADM group. CONCLUSIONS: The current study demonstrated that 1) ADM could reduce the incidence of FS in the patients undergoing superficial parotidectomy. 2) the peak onset of about 18 months appear to be acceptable follow-up for the development of FS.

Objective: To investigate whether the clinical and radiographical outcomes are affected when four or six implants support the maxillary fixed complete denture (FCD). Materials and methods: This study was registered on PROSPERO (CRD42021226432) and followed the PRISMA guidelines. The focused PICO question was, "For an edentulous maxillary patient rehabilitated with an implant-supported fixed prosthesis, do the clinical and radiographical outcomes differ when four or six implants support the prosthesis ". A thorough search of the relevant studies was designed and performed electronically. The survival rate of implant and prosthesis, marginal bone loss, and complications (mechanical and biological) were the primary outcomes, whereas implant distribution and using the surgical guide, follow-up, and framework material were evaluated as secondary outcomes. Results: Out of 1099 articles initially retrieved, 53 clearly stated the outcomes of interest and were included in this study. There were no significant differences in implant and prosthesis survival, technical/mechanical complications, and biological complications between the 4-implant group (4-IG) and the 6-implant group (6-IG). However, marginal bone loss (MBL) was significantly higher in the 4-IG (p < 0.01). The surgical guide and follow-up period did not significantly affect implant/prosthesis survival. Additionally, using the CAD/CAM milled framework and anteroposterior implant distribution were associated with significantly higher implant survival in the 6-IG (p < 0.01). Conclusion: The findings of this study indicated that having a greater number of implants, as seen in the 6-implant group, can lead to a decrease in technical and biological complications and reduce marginal bone loss. It is worth noting that factors such as using CAD/CAM frameworks and the anteroposterior distribution of implants were recognized as important in improving implant survival rates when more implants are present.
RESUMO
BACKGROUND: A poor evidence basis exists regarding direct comparing objective and subjective donor site morbidity associated with forearm flap. The authors evaluated the postoperative donor-site complications and quality of life outcomes between radial forearm free flap (RFFF) and ulnar forearm free flap (UFFF). METHODS: All patients undergoing RFFF or UFFF harvest were included. Grip strength, pinch strength, wrist range of movement, and testing skin sensitivity were assessed with the appropriate scales at different time intervals. In addition, cosmetic and quality of life were assessed using the Patient and Observer Scar Assessment Scale (POSAS) and Disability of Arm, Shoulder, and Hand (DASH) score. RESULTS: Eighty patients were enrolled (40 RFFF and 40 UFFF). The results showed a short-term reduction in grip strength, fine motor skills (tip pinch, key pinch, palmar pinch), and range of motion was observed for RFFF and improved over time. None of the patients in either group experienced functional disturbance in grip strength, wrist motion, fine motor skills, or sensation to light touch at 1 year. Nine patients experienced partial skin graft loss (RFFF = 6; UFFF = 3). There was a significantly higher incidence of temporary numbness in the RFFF group (p=0.040). Persistent numbness occurred in 3 cases in RFFF. Cold intolerance was significantly lower in UFFF (2.5 %) than in RFFF (22.5%). Moreover, the mean POSAS and DASH score reduced at 12 months compared to 6 months, significantly superior for UFFF. CONCLUSION: Objective function limitations are reversible short-term effects after forearm flap and do not affect daily routines in the long term. Additionally, UFFF appears to be preferred over RFFF for subjective outcomes, which emphasizes the UFFF should be considered an alternative to RFFF for reconstructing soft-tissue defects.
RESUMO
OBJECTIVE: To explore the incidence of postoperative complications and investigate the impact of preselected factors on functional and quality of life outcomes following the Sommerlad-Furlow modified palatoplasty technique. STUDY DESIGN: Retrospective cohort. METHODS: A total of 429 patients with cleft palate, who received Sommerlad-Furlow modified technique between 2011-2017 were enrolled. The postoperative complications including oronasal fistula (ONF), velopharyngeal insufficiency (VPI), and inadequate quality of life (QOL) were collected. Data of preselected factors including gender, age at palatoplasty, cleft type, cleft width, palatal width, pharyngeal cavity depth, and operation duration were also collected. RESULTS: Among 429 patients, 40.1% were males whereas 59.9% were females. The mean age at palatoplasty was 1.23 ± 0.69 (0.42-4) years, and the average cleft width was 10.15 ± 2.95 (4-27) mm. The cleft types had recorded rates of about 6.8%, 69.5%, 17.7%, and 6.1% of Veau I, II, III, and IV, respectively. The overall incidence rates of ONF, VPI, and inadequate QOL were 2.3%, 19.4%, and 31.3%, respectively. In both the univariate and multivariate analyses, the cleft type was significantly implicated in ONF formation (p = 0.023 and 0.032, respectively) whereas the velopharyngeal function was impacted by the palatoplasty age (p Ë 0.001). The receiver operating characteristic curve indicated that age of palatoplasty ≥1.3 years (area under the curve = 0.611, p = 0.002) was the cutoff value for predicting the incidence of VPI. CONCLUSIONS: The Sommerlad-Furlow modified technique appears to have appropriate postoperative outcomes, even in the wide cleft palate. The older age at palatoplasty has a major impact on the overall postoperative outcomes. LEVEL OF EVIDENCE: 4 Laryngoscope, 133:822-829, 2023.

BACKGROUND: There is a shortage of well-designed self-controlled studies evaluating hand biomechanics following ulnar forearm flap (UFF) harvest. This study was conducted to evaluate objective and subjective functional outcomes of the donor's hand following UFF harvest. METHODS: All patients undergoing UFF were included for analysis. Grip strength, wrist movement, forearm supination and pronation, pinch strengths, sensation to light touch and temperature, and hand dexterity were assessed preoperatively and at 1, 3, and 6 months postoperatively. In addition, DASH score (disabilities of the arm, shoulder, and hand score) and Patient and Observer Scar Assessment Scale (POSAS) were analyzed. RESULTS: A total of 18 patients were enrolled. A significant reduction in grip strength for donor's hand was observed between preoperative and postoperative 1 and 3 months (mean difference = 14 kg, 7.38 kg, respectively, p = 0.000 for all). A similar trend was observed for pinch strength and range of motion (p < 0.05). Three months after surgery, there is still a significant reduction in tip pinch, tripod pinch, wrist extension, and supination. All biomechanics outcomes returned to preoperative baseline at 6 months after surgery. No patients suffered significant changes in sensation to light touch, temperature, and numbness by 6 months. There was a significant increase in DASH score by 3.37 points 6 months after operation (p = 0.000). The POSAS score indicates satisfaction with the appearance of the donor site. CONCLUSIONS: UFF is a safe and reliable option for oral cavity reconstruction with minimum donor site morbidities, mainly when cosmesis is paramount. Furthermore, objective hand biomechanics ultimately returns to its preoperative state within 6 months after surgery.

OBJECTIVE: The clinical benefits of simultaneous implant placement and soft tissue augmentation using different treatment modalities are unclear. The current meta-analysis aimed to compare the effect of simultaneous soft tissue augmentation using subepithelial connective tissue graft (SCTG) around immediate or delayed dental implant placement with other treatment modalities on the peri-implant tissue health and esthetic. METHODS: Up to May 2021, four databases (PubMed, EMBASE, Cochrane Central, and Google Scholar) were searched. Randomized control trials with follow-up >3 months, evaluating simultaneous implant placement (immediate or delayed) and soft tissue augmentation using SCTG compared with other treatment modalities were included. The predictor variables were SCTG versus no augmentation with/without guided bone regeneration (GBR) or other augmentation techniques (Acellular dermal matrix (ADM), Xenogeneic collagen matrix (XCM). The outcome variables were buccal tissue thickness (BTT), mid-buccal gingival level (MGL), marginal bone loss (MBL), and pink esthetic scores (PES). Cumulative mean differences (MD) and 95% confidence interval (CI) were estimated. RESULTS: Twelve studies were included. SCTG along with immediate implant placement (IIP) or delayed implant placement (DIP) showed a statistically significant improvement in BTT (Fixed; MD, 0.74; 95% CI, 0.51; 0.97), MGL (Fixed; MD, 0.5; 95% CI, 0.21; 0.80), PES (Fixed; MD, 0.79; 95% CI, 0.29; 1.29), and less MBL (Fixed; MD, -0.11; 95% CI, -0.14; -0.08) compared to no graft (P<0.05). A statistically insignificant differences in BTT (Random; MD, 0.62; 95% CI, -0.41; 1.65), MGL (Fixed; MD, -0.06; 95% CI, -0.23; 0.11), MBL (Fixed; MD, 0.36; 95% CI, -0.05; 0.77) and PES (Fixed; MD, 0.28; 95% CI, -0.10; 0.67) was observed when SCTG along with DIP was compared with no augmentation plus GBR. Similarly, no statistically significant difference was observed when comparing SCTG along with DIP with acellular dermal matrix (ADM) concerning BTT (MD:0.71, P = 0.18) and KMW (MD: 0.6, P = 0.19). CONCLUSION: There is a very low quality of evidence to provide recommendations on whether simultaneous dental implant placement (IIP or DIP) and soft tissue augmentation using SCTG is superior to no augmentation or is comparable to the other tissue augmentation materials in improving the quality and quantity of peri-implant tissues. Therefore, further, well-designed RCTs with larger sample sizes and long follow-up times are still needed.

OBJECTIVE: Admission to the intensive care unit (ICU) has long been considered as routine by most head and neck surgeons after microvascular free-flap transfer. This study aimed to answer the question 'Is there a difference in the flap survival and postoperative complications rates between admission to intensive care unit (ICU) versus Non-ICU following microvascular head and neck reconstructive surgery?'. DESIGN: Systematic review, and meta-analysis. METHODS: The PubMed, Embase, Scopus and Cochrane Library electronic databases were systematically searched (till April 2021) to identify the relevant studies. Studies that compared postoperative nursing of patients who underwent microvascular head and neck reconstructive surgery in ICU and non-ICU were included. The outcome variables were flap failure and length of hospital stay (LOS) and other complications. Weighted OR or mean differences with 95% CIs were calculated. RESULTS: Eight studies involving a total of 2349 patients were included. No statistically significant differences were observed between ICU and non-ICU admitted patients regarding flap survival reported (fixed, risk ratio, 1.46; 95% CI 0.80 to 2.69, p=0.231, I2=0%), reoperation, readmission, respiratory failure, delirium and mortality (p>0.05). A significant increase in the postoperative pneumonia (p=0.018) and sepsis (p=0.033) was observed in patients admitted to ICU compared with non-ICU setting. CONCLUSION: This meta-analysis showed that an immediate postoperative nursing in the ICU after head and neck microvascular reconstructive surgery did not reduce the incidence of flap failure or complications rate. Limiting the routine ICU admission to the carefully selected patients may result in a reduction in the incidence of postoperative pneumonia, sepsis, LOS and total hospital charge.

PURPOSE: To evaluate the effect of overdenture (OD) attachment type and the number of implants supporting mandibular ODs on peri-implant health. STUDY SELECTION: From inception to October 2020, electronic databases (Medline/PubMed, Embase, Cochrane Library, and Scopus) were systematically searched. The outcomes of interest were marginal bone loss (MBL), pocket probing depth (PPD), plaque index, bleeding index, and implant survival rate. Bayesian network meta-analysis was performed using the GeMTC package supported by R. The weighted mean difference and 95% credible interval were estimated. RESULTS: Twenty-eight studies with a total of 1166 participants who received 2666 dental implants were included. Except for 4 bar and 4 telescopic, which showed a statistically lower MBL than the 2 locator, all other interventions showed insignificant differences in MBL (P > 0.05). The difference in periodontal probing depth was not statistically significant when comparing the different groups. The pooled implant survival rates of the different interventions ranged from 88.9% to 100%. The rank probability test showed that 4 bar and 4 telescopic had the lowest MBL, 2 magnet and 2 bar had the highest PI, whereas 4 locator showed the least PPD. CONCLUSION: Except for 4 implants+bar, or telescopic, and 4 locator that, respectively, showed less MBL and PPD compared to some interventions, it seemed that different attachment types and number of implants supporting mandibular ODs have no clear superiority over the other in terms of peri-implant health outcomes.

BACKGROUND: This study aimed to introduce a novel loop neurorrhaphy technique using an innervated vascularized iliac bone flap (VIBF) with vascularized ilioinguinal nerve (IIN) to reconstruct the inferior alveolar nerve (IAN) and preserve lower lip sensation simultaneously with mandibular reconstruction. METHODS: This study prospectively included patients who underwent mandibular reconstruction using VIBF from May 2018 to April 2020. Subjects were allocated into two groups: (1) Group I; innervated VIBF with loop neurorrhaphy (IIN doubly anastomosed with IAN and mental nerve), (2) Group II (control); conventional VIBF. Evaluation was done with operative time, intraoperative indocyanine green (ICG), lower lip sensory assessment (two-point discrimination [TPD] test and current perception threshold [CPT]), and drooling. RESULTS: Twelve patients were included; 6 in each group, (7 males and 5 females), age ranging from 18 to 57 years (average: 36.75 years). In all cases, intraoperative perfusion of IIN was confirmed by ICG. Group I showed a statistically significant more flap harvesting time compared with group II (mean difference, 5.67 min; P = 0.0091). There was a significant difference in sensory recovery favoring group I (P < 0.05). The TPD results in group I showed an average of 9.8 ± 6.9 mm and 6.2 ± 5.7 mm on operated and non-operated sides, while Group II showed a poor sensory recovery, and the TPD showed an average of 24.6 ± 6.7 mm and 8.4 ± 2.3 mm on operated and non-operated sides. The CPT results showed a significant difference between both groups. In Group I, the extent of drooling was 3.16 ± 0.75, while in Group II, the score was 1.6 ± 0.81, revealing a significant difference favoring Group I. CONCLUSIONS: Concurrent mandibular reconstruction using VIBF and loop neurorrhaphy with vascularized IIN to reconstruct IAN successfully restore lower jaw form and preserve lip sensation.

The clinical implications of great auricular nerve (GAN) preservation or sacrifice during parotid surgery have long been a topic of controversy. This study aimed to compare sensory recovery rates and quality of life (QoL) in patients who had undergone superficial parotidectomy and had their GAN preserved or sacrificed. Fifty patients were prospectively analysed, 28 with the GAN preserved, and 22 with it sacrificed. The primary outcomes were tactile sensitivity and QoL. The secondary outcomes were operating times and other complications. There was a gradual improvement in tactile sensitivity in both groups, which showed a statistically significant difference favouring the preserved group at 1, 3, 6, and 9 months postoperatively (p<0.05). There was no statistically significant difference in tactile sensation for both groups at 12 months postoperatively. The overall sensory recovery rates in the GAN preserved and sacrificed groups after 1, 3 ,6, 9 and 12 months were 42.8%, 42.8%, 57.1%, 57.1%, and 78.5%, and 0%, 0%, 13.6%, 27.3%, and 59.1%, respectively. According to the QoL assessment, there was a significant difference in mean (SD) loss of sensation scores (sacrificed group 0.86 (0.94) and preserved group 0.39 (0.62), p= 0.039). However, there were no statistical differences between the groups regarding other categories of the questionnaire. No significant difference was seen between groups regarding operating time and other complications. This study concluded that when evaluated objectively, sensory impairment ultimately lessened in severity in the second half of the first postoperative year. GAN preservation minimised sensation disturbance in long-term results, but overall QoL seemed to be unaffected following GAN preservation or sacrifice.

AIM: The early detection of oral cancer (OC) at the earliest stage significantly increases survival rates. Recently, there has been an increasing interest in the use of artificial intelligence (AI) technologies in diagnostic medicine. This study aimed to critically analyse the available evidence concerning the utility of AI in the diagnosis of OC. Special consideration was given to the diagnostic accuracy of AI and its ability to identify the early stages of OC. MATERIALS AND METHODS: From the date of inception to December 2021, 4 databases (PubMed, Scopus, EBSCO, and OVID) were searched. Three independent authors selected studies on the basis of strict inclusion criteria. The risk of bias and applicability were assessed using the prediction model risk of bias assessment tool. Of the 606 initial records, 17 studies with a total of 7245 patients and 69,425 images were included. Ten statistical methods were used to assess AI performance in the included studies. Six studies used supervised machine learning, whilst 11 used deep learning. The results of deep learning ranged with an accuracy of 81% to 99.7%, sensitivity 79% to 98.75%, specificity 82% to 100%, and area under the curve (AUC) 79% to 99.5%. RESULTS: Results obtained from supervised machine learning demonstrated an accuracy ranging from 43.5% to 100%, sensitivity of 94% to 100%, specificity 16% to 100%, and AUC of 93%. CONCLUSIONS: There is no clear consensus regarding the best AI method for OC detection. AI is a valuable diagnostic tool that represents a large evolutionary leap in the detection of OC in its early stages. Based on the evidence, deep learning, such as a deep convolutional neural network, is more accurate in the early detection of OC compared to supervised machine learning.
