RESUMO
OBJECTIVE: This study aimed to compare the nasopharynx and oropharynx airway dimensions of Caucasians, Blacks, Japanese, Japanese Brazilians, and Black Caucasians. METHODS: A sample of 216 lateral radiographs of untreated young Brazilian subjects (mean age of 12.94 years; SD 0.88) were divided into five groups: Black Caucasian, Black, Caucasian, Japanese, and Japanese Brazilian. Lateral radiographs were used to measure the oropharynx (from the midpoint on the soft palate to the closest point on the anterior pharyngeal wall) and the nasopharynx (from the intersection of the posterior border of the tongue and the inferior border of the mandible to the closest point on the posterior pharyngeal wall). Analyses of variance (ANOVA) and Tukey's test were performed (p< 0.05). RESULTS: The linear dimension of the oropharynx was similar among the different ethnic groups. Caucasian individuals presented a significantly greater linear dimension of the nasopharynx than Black Caucasian and Black individuals. CONCLUSIONS: All the groups had similar buccopharyngeal values. However, Caucasian individuals had significantly higher values when compared to Black Caucasians and Black individuals.

BACKGROUND: Palatal lengthening is becoming a first-line treatment choice for cleft patients with velopharyngeal insufficiency (VPI). As cleft palate-related surgical outcomes are age dependent, speech outcomes may be similarly affected by patient age at the time of treatment. The primary goal of this study is to determine whether there are age-related speech outcome differences when double opposing buccinator myomucosal flaps are used as part of a palatal lengthening protocol and whether these outcome differences preclude utilization of this technique for specific patient age groups. METHODS: A retrospective study was performed on consecutive nonsyndromic patients with VPI who underwent treatment using double opposing buccinator myomucosal flaps at our hospital between 2014 and 2021. Patients who completed the 15-month follow-up were stratified by age. Group A aged between 2 and 7 years (n = 14), group B aged 8 and 18 years (n = 23), and group C aged older than 18 years (n = 25) were included. Standardized perceptual speech evaluations and nasopharyngoscopy were performed. Hypernasality, soft palate mobility, and lateral palatal wall mobility were assessed both preoperatively and at a 15-month postoperative interval. Complications were also recorded. The χ2 test was used for statistical comparison. RESULTS: All of the age-stratified patient groups in this study showed significant improvement in hypernasality, soft palate mobility, and lateral wall mobility (P < 0.01), with no statistically significant differences between the different patient age groups. Overall speech success was achieved in 69.4% of patients. Patients in group A achieved 78.6% speech success, patients in group B achieved 78.3% speech success, and patients in group C achieved 56% speech success, with no statistically significant differences being shown regarding speech success between the different patient age groups (P > 0.05). CONCLUSIONS: Regardless of age, palatal lengthening via double opposing buccinator myomucosal flaps similarly improves speech outcomes.

Basal cell adenocarcinoma (BCAd) is an extremely rare primary biphasic carcinoma of the salivary glands with few well-documented cases reported in the literature. Herein, we report a rare case of a 44-year-old male patient who presented an oral medicine service with an erythematous nodular lesion on the soft palate, measuring 1.5 cm in its largest diameter, with a 5-year duration. The clinical diagnosis was pleomorphic adenoma, and an excisional biopsy was performed. Histopathological analysis revealed a biphasic infiltrative tumor composed of a mixture of central ductal cells and abluminal basal cells with slight atypia arranged in solid, trabecular, tubular and cribriform growth patterns in a loose stroma. The peripheral cells show a palisading arrangement with round hyperchromatic nuclei and scanty cytoplasm. Occasional mitotic figures were seen. Few spindle-shaped cells suggestive of myoepithelial cells were present in the stroma surrounding the basaloid tumor nests. The diagnosis was BCAd. The patient was referred to a head and neck service and has been followed up for 8 months with no signs of recurrence. In conclusion, although the diagnosis of BCAd can be challenging due to its rarity and morphological overlap with other salivary gland lesions, a meticulous morphological assessment is key for accurate diagnosis, especially in cases originating from minor salivary glands. Surgical excision with a wide safety margin is the treatment of choice and long-term follow-up is recommended to monitor possible recurrences.

PURPOSE: To assess the impact of 1 and 2-stage palatoplasty protocol on the dental arch relationships in unilateral cleft lip and palate (UCLP) in a single center. METHODS: Our study consisted of 349 individuals divided into 2 groups according to the palatoplasty protocol. Two-stage group comprised 169 subjects with UCLP (mean age: 6.9 y, 110 male and 59 female) who underwent lip, nasal ala, and anterior palate repair with vomer flap from 3 to 6 months (first surgery stage). Soft palate repair occurred from 12 to 18 months (second surgery stage). The one-stage group comprised 180 subjects with UCLP (mean age: 7.2 y, 108 male and 72 female) who underwent 1-stage palatoplasty. Dental models were evaluated by 3 experienced orthodontists applying Goslon Yardstick and the 5-year-old index (FYOI). The influence of the palatoplasty technique and surgeon factor on the interarch relationship was evaluated. The weighted Kappa was used to assess intraexaminer and interexaminer agreements for comparisons of dental arch relationships. Intergroup comparisons were conducted using the χ 2 test ( P <0.05). RESULTS: The intraexaminer reliability was very good (0.81 to 0.98) and interexaminer reliability varied from satisfactory to very good (0.56 to 0.83). The mean occlusal index of the 2-stage and 1-stage groups was 2.77 and 3.03, respectively. The variability of the mean index between surgeons varied from 2.38 to 3.2 in the 2-stage group and 2.91 to 3.2 in the 1-stage group. There were significant differences in the frequency of Goslon 5 index ( P =0.002) between groups, with the 2-stage group presenting less cases (1.18%) than the group 1-stage (11.11%). CONCLUSION: The interarch relationship was similar for both palate repair protocols. Two-stage palatoplasty showed a decreased prevalence of Goslon index 5.

BACKGROUND: Numerous authors have reported their outcomes after using Furlow's palatoplasty for cleft palate repair. However, little attention has been given to the operative complications associated with this technique. The present study was carried out to present cases and analyze the various factors influencing the development of this complication accompanying Furlow's palatoplasty. MATERIALS AND METHODS: This is a case report study of patients with cleft palate admitted to our center due to sequelae after primary cleft palate repair using Furlow palatoplasty between 2003 and 2021. Patient information was identified from the Smile Train cleft charity organization, parents' reports, and hospital records (intake forms and operating room registries). RESULTS: Five patients were identified as having secondary cleft palate with palatal flap necrosis and associated with Furlow palatoplasty during patient evaluation at our center between 2003 and 2021. The observed prevalence was 1.54%. CONCLUSIONS: Palatal flap necrosis is a rare but serious complication after primary Furlow's palatoplasty. The occurrence of this complication can be reduced by careful preoperative planning, and prevention is possible.

PURPOSE: The aim of the study was to investigate a possible relationship between pharyngeal airway space, craniofacial variables, and dental arch form in adolescents grouped by sex. METHODS: This cross-sectional study included 108 adolescents aged between 12 and 17 years. Lateral cephalometric radiographs were used to analyze sagittal craniofacial variables and the pharyngeal airway space. For evaluation of the dental arch form, we used plaster models. Statistical analysis included Student's ttest and Pearson's correlation coefficient (r). RESULTS: Maxillary length was directly proportional to upper nasopharyngeal airway dimensions in males (râ¯= 0.312, pâ¯= 0.021) and females (râ¯= 0.310, pâ¯= 0.022). In the female group, upper oropharyngeal measurements showed an inverse correlation with a labial inclination of the upper incisors (râ¯= -0.415, pâ¯= 0.001), protrusion of the upper incisors (râ¯= -0.364, pâ¯= 0.006), and soft palate thickness (râ¯= -0.27, pâ¯= 0.043). In the male group, upper nasopharynx measurements showed an inverse correlation with soft palate thickness (râ¯= -0.277, pâ¯= 0.042). The upper arch form appeared to be related to oropharyngeal measurements in females, while the lower arch form was related to oropharyngeal dimensions in males. CONCLUSION: The findings suggest that there are sex-dependent correlations of the nasopharyngeal and oropharyngeal airway space with the sagittal craniofacial morphology and the transversal dental arch form.

Objective: whether gag reflex, a common problem encountered during dental procedures, is associated with the different types of the soft palate has not been addressed so far. This preliminary study sought to assess the potential association between the different types of soft palate and gag reflex. Material and Methods: one hundred dental patients were recruited. The type of soft palate was determined. Subjective (self-reported) gag reflex was recorded based on many questions and past experience and on a 0-6 VAS. Objective assessment of gag reflex was done using different maneuvers where the posterior part of the tongue and the soft palate were touched by dental mirror, and by taking impression for the upper arch. The association between the types of soft palate and the subjective and objective recorded gag reflex were statistically tested. Results: there were 53 (53%), 33 (33%) and 14 (14%) of the participants with class I, class II and class III soft palate, respectively. A significant association was found between the type of the soft palate and gag reflex in response to one of the subjective items (P= 0.039), more prominent among females (P= 0.009). Concerning the objective assessment, no significant associations were found among males. Meanwhile more females with class II and class III suffered gag reflex and/or actual gagging upon taking the impression (P = 0.001). Conclusion: this study illustrated an association between the type of soft palate and gag reflex, and its severity in females (more specifically soft palate types II and III) more than in males (AU)
Objetivo: o reflexo de vômito, um problema comum encontrado durante procedimentos odontológicos, está ou não associado aos diferentes tipos de palato mole, não foi ainda abordado até o momento. Este estudo preliminar procurou avaliar a possível associação entre os diferentes tipos de palato mole e o reflexo de vômito. Material e Métodos:cem pacientes odontológicos foram recrutados. O tipo de palato mole foi determinado. O reflexo de vômito subjetivo (auto-relatado) foi registrado com base em muitas perguntas e experiências anteriores e em um VAS de 0-6. A avaliação objetiva do reflexo de vômito foi feita por meio de diferentes manobras onde a parte posterior da língua e o palato mole foram tocados por espelho dental e por meio de moldagem da arcada superior. A associação entre os tipos de palato mole e o reflexo de vômito subjetivo e objetivo registrado foi testada estatisticamente. Resultados: houve 53 (53%), 33 (33%) e 14 (14%) participantes com palato mole classe I, classe II e classe III, respectivamente. Foi encontrada associação significativa entre o tipo de palato mole e o reflexo de vômito em resposta a um dos itens subjetivos (P= 0,039), mais proeminente no sexo feminino (P= 0,009). Em relação à avaliação objetiva, não foram encontradas associações significativas entre os homens. Enquanto isso, mais mulheres com classe II e classe III sofreram reflexo de vômito e/ou engasgo real ao receber a impressão (P = 0,001). Conclusão: este estudo ilustrou uma associação entre o tipo de palato mole e reflexo de vômito e sua gravidade em mulheres (mais especificamente palato mole tipos II e III) mais do que em homens.
