Customized Subperiosteal Implants for the Rehabilitation of Atrophic Jaws: A Consensus Report and Literature Review.

(1) Background: The aim was to perform a literature review on customized subperiosteal implants (CSIs) and provide clinical guidelines based on the results of an expert consensus meeting held in 2023. (2) Methods: A literature search was performed in Pubmed (MEDLINE) in July 2023, including case series and cohort studies with a minimum follow-up of 6 months that analyzed totally or partially edentulous patients treated with CSIs. Previously, an expert consensus meeting had been held in May 2023 to establish the most relevant clinical guidelines. (3) Results: Six papers (four case series and two retrospective cohort studies) were finally included in the review. Biological and mechanical complication rates ranged from 5.7% to 43.8% and from 6.3% to 20%, respectively. Thorough digital planning to ensure the passive fit of the CSI is mandatory to avoid implant failure. (4) Conclusions: CSIs are a promising treatment option for rehabilitating edentulous patients with atrophic jaws; they seem to have an excellent short-term survival rate, a low incidence of major complications, and less morbidity in comparison with complex bone grafting procedures. As the available data on the use of CSIs are very scarce, it is not possible to establish clinical recommendations based on scientific evidence.

Neurotrophic Keratitis in a Pediatric Patient With Goldenhar Syndrome and Trigeminal Aplasia Successfully Treated by Corneal Neurotization.

Herein, the authors report an unusual case of a 6-year-old boy with right-sided Goldenhar syndrome and trigeminal nerve aplasia who developed neurotrophic keratopathy (NK). Despite the use of therapeutic contact lenses and multiple temporary tarsorrhaphy, NK worsened showing a central corneal scar, neovascularization, and significant stromal thinning, with risk of corneal perforation. Cochet-Bonnet esthesiometry revealed complete corneal anesthesia. To minimize additional corneal complications, the patient underwent indirect corneal neurotization by a sural nerve autograft anastomosed to the contralateral supratrochlear nerve. At 24-month follow up, no epithelial defects, complications, or recurrence were observed. Significant improvements in corneal sensitivity with esthesiometry score of 20 mm and reflex blinking were achieved. This case highlights corneal anesthesia should be suspected among Goldenhar syndrome ophthalmologic abnormalities and monitored before corneal changes become irreversible. Since corneal neurotization can successfully improve corneal sensation, it could be considered as an early therapeutic option to avoid refractory NK.

Sentinel Lymph Node Biopsy in Oral and Oropharyngeal Squamous Cell Carcinoma: Statistical Validation and Impact of Micrometastasis Involvement on the Neck Dissection Decision.

PURPOSE: To evaluate the effectiveness of sentinel lymph node biopsy (SLNB) as an optimal staging method in oral and oropharyngeal squamous cell carcinoma (OOSCC) and the impact of the extent of SLN involvement on the decision for neck dissection (ND). MATERIALS AND METHODS: A prospective cohort study was performed in 96 consecutive patients with stage T1 to T4N0M0 OOSCC (mean follow-up, 62.9 months). SLN localization was determined using cervical lymphoscintigraphy and single-photon emission computed tomography. Patients underwent SLNB examination and ND. The ND specimen was investigated by hematoxylin and eosin (H&E) staining and the SLNs were investigated using H&E staining and step-serial sectioning and cytokeratin antibodies AE1 and AE3. The statistical study calculated the sensitivity and negative predictive value (NPV). The sample size of 96 patients was calculated for a 95% confidence interval with an accuracy of ±2% and an estimated a priori sensitivity of 99% compared with the benchmark. The impact of extent of SLN involvement on the decision for ND was analyzed by χ(2) test. A logistic regression model was used to assess the association of predictor variables with SLN involvement and neck disease. RESULTS: The diagnostic accuracy, sensitivity, NPV, and negative likelihood ratio were 95%, 88%, 94%, and 0.06. The statistical comparison between the extent of metastatic involvement of the SLN and neck disease was important for SLN macrometastasis (odds ratio = 11.9), but not for SLN micrometastasis (odds ratio = 0.93). CONCLUSIONS: SLNB examination is an excellent staging method in OOSCC. The present data indicate a very small risk of additional lymph node metastasis with SLN micrometastasis.

Quality of life in long-term oral cancer survivors: a comparison with Spanish general population norms.

PURPOSE: Health-related quality-of-life (HRQOL) data are becoming an important supplement to information pertaining to treatment outcomes for cancer patients. The purpose of this study was to evaluate the HRQOL of patients undergoing primary surgery for oral squamous cell carcinoma > or =5 years after treatment compared with the Spanish general population norms. MATERIALS AND METHODS: A total of 50 oral cancer patients (mean age 55.78 years, 80% male) with cancer-free survival of > or =5 years after surgery were enrolled. HRQOL was assessed with a standardized questionnaire: the Medical Outcomes Study Short Form 36-Item Health Survey. RESULTS: The Medical Outcomes Study Short Form 36-Item Health Survey scores of the oral cancer patients did not differ significantly from those of an age- and gender-matched sample from the Spanish normative population, except for the pain and social functioning domains. The patients had significantly better results compared with the population norms (Wilcoxon test, P < .05) in the physical function, general health, and vitality domains. CONCLUSIONS: These results provide patient-reported evidence that oral cancer survivors have a similar HRQOL compared with the general Spanish population. We also believe that it would be necessary to analyze the quality of life > or =5 years after treatment or from the moment the patient was discharged.

Synchronous unilateral parotid neoplasms. A case report.

The parotid gland is the most usual location of benign neoplasms affecting major salivary glands and quite often the recurrence of these tumours is noticed, specially in the case of pleomorphic adenoma. The occurrence of multiple tumours in the parotid glands is rare and the majority of these are multifocal Warthin's tumors (papillary cystadenoma lymphomatosum). The simultaneous development of tumours with different histological types is unusual and when it occurs, the most common combination is a pleomorphic adenoma and a Warthin's tumor. There are many articles about Multiple Parotid Tumors (MPT) but only a few of them are focused on unilateral synchronous benings tumors, being pleomorphic adenoma and Warthin's these tumors. The report describes a 55 year old female with a pleomorphic adenoma occurring synchronously with a Warthin's tumor within the superficial lobe of her left parotid gland.
