Clinical profile and outcomes of tetanus patients in a tertiary hospital in the Philippines: a ten-year retrospective study.

BACKGROUND: Tetanus is a life-threatening but preventable neurologic disorder characterized by trismus and muscle spasms. Despite its decreasing global incidence, it remains to be endemic in resource-limited settings such as the Philippines. This study aimed to determine the incidence, demographic characteristics, risk factors, clinical presentation, management, complications, and outcomes of non-neonatal tetanus cases in a tertiary hospital in the Philippines. It also aimed to compare the clinical profile and outcomes between the adult and pediatric subgroups. METHODS: This study used a retrospective cross-sectional design including all adult and pediatric non-neonatal tetanus patients admitted at the University of the Philippines - Philippine General Hospital from January 2012 to June 2023. Data was extracted from department censuses and inpatient charts. RESULTS: One hundred thirty-eight cases were included. The incidence rate was 0.03%, while mortality rate was 29%. Majority of patients were males presenting with trismus and spasms after sustaining a puncture wound. Chronic hypertension was associated with an increased hazard of death by 4.5 times (p = 0.004), while treatment with magnesium sulfate was associated with a decreased hazard of death by 35 times (p = 0.005). The mode of infection and the medications administered differed between the adult and pediatric subgroups. CONCLUSIONS: Although the total number of cases has decreased over the past decade, tetanus remains to have a high incidence and mortality rate in the Philippines. Increasing vaccination coverage, improving public awareness, and educating health professionals can help reduce morbidity and mortality from this disease.

Case Report: A Challenging Case of Tetanus Presenting with Headache.

Tetanus is a life-threatening infectious neurological condition that has become uncommon due to large-scale immunization campaigns. We describe a rare instance of generalized tetanus presenting with a headache on a tropical island in Malaysia. A 43-year-old woman presenting with headaches and generalized body weakness, which progressed into trismus and neck stiffness. Her medical history indicated a wound on the sole of her foot caused by shattered glass in an unhygienic area, but no tetanus prophylaxis had been administered. The patient was subsequently given immunoglobulin, tetanus toxoid, metronidazole, and sedatives in the recommended dosages. Her neurological condition improved remarkably, but she suffered blood pressure fluctuations due to dysautonomia. She was successfully discharged with complete recovery after 6 months of follow-up. The case demonstrates the significance of appropriate identification and care of tetanus, as well as the lethal effects of untreated wounds in vulnerable patients.

Trismus due to myotonia associated with hyperadrenocorticism in a dog.

We present the report of trismus due to hyperadrenocorticism-associated myotonia diagnosed by electromyography in a dog. An intact female Miniature Dachshund, 13 years and 9 months old, presented with stiff gait and trismus as well as polyuria and polydipsia. Abdominal ultrasonography showed enlarged adrenal glands. An adrenocorticotropic hormone stimulation test revealed an exaggerated response. Based on these findings, this case was diagnosed with hyperadrenocorticism. Electromyography revealed myotonic discharge in the temporalis muscle and limbs. Therefore, trismus was considered to be caused by hyperadrenocorticism-associated myotonia, and the case was treated with oral trilostane (1.3 mg/kg, once daily). During the 4-month follow-up period, despite the partial improvement in stiff gait, trismus did not recover. Long-term data on more cases are warranted to assess the prognosis and clinical characteristics of trismus due to hyperadrenocorticism-associated myotonia.

Analysis of the Clinical Status and Treatment of Facial Cellulitis of Odontogenic Origin in Pediatric Patients.

The most common cause of the development of odontogenic infection is untreated dental caries, which initially leads to pulpitis. If an odontogenic infection is left untreated, it will pass through the limiting bone plate and will infiltrate deeper structures. Odontogenic infections are different in adults and children. The study was conducted at the Department of Pediatric Otolaryngology and Pediatric Head and Neck Surgery of Upper Silesian Children's Health Center in Katowice in the 2020-2022. We included 27 patients aged 2-16 in the study. Patients were diagnosed with an active, acute odontogenic inflammatory process in the head and neck area. We assessed pain, trismus, extraoral and intraoral swelling and the level of CRP [C Reactive Protein], WBC [White Blood Cells], NLR [Neutrophil Lymphocyte Ratio], D-dimers and Prealbumins. The results were analyzed in terms of the location of the source of inflammation: maxilla or mandible and the type of source of infection: deciduous tooth or permanent tooth. Deciduous teeth are more often the cause of odontogenic infection in the maxilla, while permanent teeth in the mandible. Trismus, extraoral, and intraoral swelling occurred in all infections caused by permanent teeth. The CRP and NLR ratio is statistically higher in infection, which originates from permanent teeth. The mean hospitalization time was also longer for infections from permanent teeth 3.42 days than for deciduous teeth 2.2 days. The varied clinical picture of odontogenic infections in children requires periodic analyzes of statistical data related to epidemiology, etiology, and symptomatology in order to update diagnostic and therapeutic procedures.

Does the use of cooled saline irrigation during third molar surgery affect post-operative morbidity?

Design This study is a double-blind, single-centre, split-mouth, prospective randomised control trial. In total, 48 patients had bilateral third molars removed during two separate operations at least 21 days apart by the same maxillofacial surgeon. During the control operation, the tooth was irrigated with saline at 25°C. During the test operation, patients were randomised to tooth irrigation with saline at either 10°C (n = 24) or 4°C (n = 24). Local anaesthetic, flap design, burr design and sutures remained consistent throughout. Patients were prescribed amoxicillin, chlorhexidine and were advised to take paracetamol as needed. The patients remained blinded to which test group they were randomised to and to the order of the control or test operations performed. Participants self-recorded analgesia use and post-operative pain daily for seven days using a visual analogue scale (VAS). A second maxillofacial surgeon examined patients on days one, three and seven. Facial swelling was assessed by measuring the distance between various soft tissue points compared to pre-operative levels. Trismus was determined by measuring maximum inter-incisal opening compared to pre-operative levels.Case selection In total, 28 female and 20 male medically fit adult patients with a mean age of 24.6 ± 3.8 with bilateral mandibular asymptomatic third molar teeth were selected. Second molars with periodontal probing depths >4 mm or impacted third molars associated with cysts or tumours were excluded. Patients had no antibiotic prescription in the preceding month nor analgesic consumption in the 12 hours before surgery.Data analysis The Shapiro-Wilk test was used to evaluate if the sample fit a normal distribution. Relationships between the categorical variables of the groups was tested using chi-square statistics. Data comparisons were examined with the Duncan, Kriskal-Wallis, Dunn and Friedman test (p <0.05).Results The median duration of the control and test group operations were similar (p = 0.051). Test group patients reported lower pain VAS values and consumed less analgesics compared to the control groups (p = 0.001), with the lowest values seen in the 4°C group (p <0.001). A greater decrease in trismus levels was also seen on day three and seven in the test groups (p <0.001) compared to the control group (p = 0.07). Swelling was greatest in the control group (p <0.001) and reduced on day seven (p <0.001) in all groups. While trismus and swelling values were lower in the 10°C test group compared to the control (p <0.001), the lowest values of these parameters at all time points was in the 4°C group (p <0.001).Conclusions Early complications following third molar removal include facial swelling, trismus and pain. In this study, intraoperative cooled saline irrigation to 4°C and 10°C was more effective than saline irrigation at 25°C in reducing the intensity of these conditions.

Single blind, randomized study comparing clinical equivalence of Trusilk ® and Mersilk ® silk sutures for mucosal closure following surgical removal of mesioangular impacted mandibular third molar.

Background: Mesioangular impacted mandibular third molar is a common dental anomaly, for which surgical extraction is required. Post-surgery closure of mucosa reduces the prevalence of pain and other surgery-associated complications. We compared tissue reaction/inflammation after 3 and 7 days of mucosal closure with Trusilk ® and Mersilk ® silk sutures, following impacted mandibular third molar removal. Methods: This multicenter, prospective, two-arm, parallel-group, randomized (1:1), single-blind study (July 2020-November 2021) included subjects (Trusilk ®, n=65 and Mersilk ®, n=64), requiring mucosal suturing following impacted mandibular third molar removal. The primary endpoint, incidence of pain, swelling and trismus at the extraction area on post-surgery day 3 and 7 was evaluated. The secondary endpoints, incidence of tissue reaction, wound infection, suture loosening, other complications, operative time, amount of anesthesia, intraoperative suture handling, time needed for complete wound healing and suture removal, and adverse events were also recorded. Results: Socio-demographic and intra-oral characteristics were comparable between the groups. In Trusilk ® and Mersilk ® groups, a gradually decreasing pain score, starting from day 0 post-surgery (42.17±22.38 vs. 45.97±22.20) to day 7 (8.40±11.93 vs. 8.28±12.13) to day 30 (1.98±0.89 vs. 1.75±0.76) was witnessed. After the surgery, 21.54% and 17.19% subjects in Trusilk ® and Mersilk ® groups, respectively, had no post-operative swelling, while at the last two visits none of the subjects had swelling. Non-significant difference in wound infection, suture loosening, wound healing, bleeding, taste changes, operative time, amount of anesthesia, intraoperative suture handling, and time needed for complete wound healing and suture removal was noted among the groups. No suture-related adverse events were recorded. Conclusions: The results indicated that the Trusilk ® and Mersilk ® silk sutures are clinically equivalent and can be used for mucosal closure after removal of an impacted mandibular third molar with a minimal rate of pain, swelling and trismus.

Peritonsillar abscess due to temporomandibular joint septic arthritis: an uncommon cause of a common disease.

Peritonsillar abscess is a common presentation of complicated acute tonsillitis. The temporomandibular joint septic arthritis is an uncommon clinical entity while its complications are further rare. We present a case of a man in his late 30s who presented with a painful swelling in the left preauricular region along with increasing trismus. A diagnosis of peritonsillar abscess due to septic arthritis was made based on clinical history and examination. Patient recovered fully after antibiotic and abscess drainage. This is the first case report of temporomandibular septic arthritis leading to peritonsillar abscess.

Age-Specific Clinical Features of Pediatric Malignant Hyperthermia: A Review of 187 Cases Over 60 Years in Japan.

BACKGROUND: Malignant hyperthermia (MH) is an inherited muscle disorder induced by volatile anesthetics and depolarizing muscle relaxants. While the incidence of MH is high in young, there are few reports on the clinical features of pediatric MH. In this study, we selected pediatric cases from an MH database and analyzed the clinical findings by age group. We hypothesized that there would be age-related differences in the clinical characteristics. METHODS: A retrospective analysis of MH data collected in our database during 1960 to 2020 was performed to identify pediatric subjects (≤18 years) with a Clinical Grading Scale of ≥35, indicating "very likely" or "almost certain" MH. We compared clinical characteristics among the 0 to 24 month, 2 to 12 year, and 13 to 18 year (youngest, middle, and oldest, respectively) age groups. RESULTS: Data were available for 187 patients: 15 in the youngest age group, 123 in the middle-aged group, and 49 in the oldest age group. Of these, 55 patients (29.4%) had undergone muscle biopsy and muscle contracture test. The mortality rates during the study period were 13.3%, 13.8%, 20.4%, and 15.5% in the youngest, middle, and oldest cohorts and overall, respectively. In contrast, the overall mortality rate from 2000 to 2020 was 8.8%. The most frequent initial symptoms of MH were elevated temperature (46.7%) and generalized muscular rigidity (26.7%) in the youngest cohort, masseter spasm (35.0%) and generalized muscular rigidity (19.5%) in the middle cohort, and elevated end-tidal carbon dioxide (26.5%) and tachycardia (22.4%) in the oldest cohort. Physical examination revealed that elevated temperature, sinus tachycardia, and respiratory acidosis occurred frequently in all groups. The middle cohort had high frequencies of masseter spasm (58.4%; P = .02) and dark urine (75.5%; P = .01) compared to those in the oldest groups, and had a higher peak creatine kinase level compared to those in the 3 groups. Skeletal muscle symptoms tended to be more common in patients administered succinylcholine (generalized muscular rigidity, P = .053; masseter spasm, P < .0001; dark urine, P < .0001). In particular, masseter spasm and dark urine were more common in the middle cohort when succinylcholine was administered (masseter spasm: versus youngest cohort, P = .06, versus oldest cohort, P = .027; dark urine: versus youngest cohort, P = .0072, versus oldest cohort, P = .0015). CONCLUSIONS: The clinical characteristics of pediatric patients with MH vary according to age group. The difference in initial symptoms of MH depending on age group is noteworthy information for the early diagnosis of MH.

Secrets to a successful awake fibreoptic intubation (AFOI) on a patient with odentogenous abscess.

Awake fibreoptic intubation (AFOI) is an established modality in patients with anticipated difficulty with tracheal intubation. This case demonstrates that with careful and meticulous preparations, AFOI can lead to improved airway management and excellent patient outcomes. A 38-year-old woman presented with severe trismus secondary to odentogenous abscess was identified preoperatively as having a potential difficult airway. AFOI was performed successfully using combined Spray-As-You-Go and dexmedetomidine technique.

Further validation of the Gothenburg Trismus Questionnaire (GTQ).

This study aimed to update and, if necessary, revise the Gothenburg Trismus Questionnaire (GTQ), the only existing trismus-specific questionnaire, and retest its psychometric properties. Semi-structured interviews were performed with 10 trismus patients of which 5 had head and neck cancer (HNC) and 5 suffered from benign temporomandibular disorders. Trismus was defined as a maximal incisal opening of ≤ 35mm. An expert panel discussed and revised the GTQ based on interview information, expertise knowledge and the original questionnaire. The revised questionnaire was then tested in a study sample consisting of benign jaw-related conditions (n = 26), patients treated for HNC (n = 90) and an age- and gender-matched control group with no trismus (n = 116). The revised version of the GTQ (GTQ 2) was well accepted by patients. The original three domains continued to show high internal consistency (Cronbach's alpha 0.74-0.94) and construct validity. Two dually posed single items were split into four questions and the wording was altered in another three items. Moreover, a new domain (Facial pain) was identified, which had excellent internal consistency (α = 0.96) and good construct validity. The revision of the original Gothenburg Trismus Questionnaire (GTQ 1) with inclusion of patient-input, resulted in splitting of ambiguous items, identifying a fourth domain named Facial pain and the recall time shortened for some items. Additionally, the remaining domains and items were re-confirmed as strong in the psychometric analysis. Henceforth, the new version, GTQ 2 should be used.

Does preoperative dental anxiety play a role in postoperative pain perception after third molar surgery?

Background: Surgical removal of the impacted third molar is associated with inflammatory morbidities which include swelling, trismus, and pain. Pain is the most common postsurgical morbidity associated with third molar surgery. It remains an important factor in patients' perception of recovery after third molar surgery with dental anxiety reported to exert influence on its threshold. Objective: The aim of the study was to determine if preoperative dental anxiety has any significant role on postoperative pain perception after third molar surgery. Materials and Methods: This was a cohort study involving sixty consecutive adult patients requiring extraction of impacted mandibular third molars under local anesthesia. Modified Dental Anxiety Scale Questionnaire was administered to each participant in the waiting area before the surgery. The visual analog scale was also given to each participant to be completed once daily at approximately the same time as the surgery time until day 7 after the surgery. Data collected were analyzed using SPSS version 23. Results: Sixty participants who consented to third molar surgery took part in this study. Five participants were lost to follow-up. There were slightly more males (50.9%) than females (49.1%). Nineteen participants in this study had moderate dental anxiety (34.5%) and 6 participants (11%) had severe dental anxiety with more females having moderate-to-severe dental anxiety. The correlation between pain perception at different days and dental anxiety was not significant (P > 0.05). Conclusion: Preoperative dental anxiety may not significantly influence pain perception after third molar surgery.

RésuméContexte: L'extraction chirurgicale de la troisième molaire incluse est souvent accompagnée d'un gonflement, d'une difficulté à ouvrir la bouche et de douleurs. La douleur est la morbidité post-chirurgicale la plus courante associée à la chirurgie de la troisième molaire. C'est un facteur important qui détermine la façon dont les patients perçoivent la guérison après une chirurgie de la troisième molaire. Il est rapporté que l'anxiété dentaire a une influence sur le seuil de douleur des patients. Objectif: Pour déterminer si l'anxiété dentaire préopératoire a un rôle significatif sur la perception de la douleur postopératoire après une chirurgie de la troisième molaire. Méthodes: Soixante patients adultes nécessitant l'extraction des troisièmes molaires incluses sous anesthésie locale ont été inclus dans cette étude de recherche. Un Modified Dental Anxiety Scale Questionnaire a été administré à chaque participant dans la salle d'attente avant la chirurgie. Le Visual Analogue Scale (VAS) a également été donnée à chaque patient à compléter une fois par jour à peu près au même moment que l'heure de la chirurgie jusqu'au jour 7 après la chirurgie. Les données obtenues ont été analysées à l'aide de la version 23 de SPSS. Résultats: Soixante patients ayant consenti à une chirurgie de la troisième molaire ont participé à cette étude. Cinq patients ont été perdus de vue. Il y avait un peu plus d'hommes (50,9%) que de femmes (49,1%). Dix-neuf patients avaient une anxiété dentaire modérée (34,5%) et 6 (11%) une anxiété dentaire sévère, un plus grand nombre de femmes ayant une anxiété dentaire modérée à sévère. La corrélation entre la perception de la douleur à différents jours et l'anxiété dentaire n'était pas significative (P> 0,05). Conclusion: L'anxiété dentaire préopératoire peut ne pas avoir d'effet significatif sur la perception de la douleur après une chirurgie de la troisième molaire.

Efeito da antibioticoterapia no pós-operatório de cirurgias de terceiros molares inferiores: estudo em boca dividida, randomizado e controlado / . Effect of antibiotic therapy in the postoperative period of inferior thirf molar surgeries: a split-mouth, randomized and controlled study

A exodontia de terceiros molares inferiores semi-inclusos ou inclusos é um dos procedimentos mais realizados dentro da cirurgia oral e inerente ao procedimento, existe uma resposta inflamatória pós-operatória. Entre os fatores mais rotineiros à esta resposta, encontram-se a dor, edema e trismo, os quais podem ser agravados na presença de infecções ou distúrbios de cicatrização da ferida cirúrgica. Entretando o uso de antibiótico no pós-operatório para beneficiar e minimizar os fatores inerentes e complicações referentes aos procedimentos, permanece sendo controverso na literatura. Dessa forma, o objetivo deste ensaio clínico, em randomizado foi avaliar o pós-operatório de 32 terceiros molares semi-inclusos ou inclusos, em boca dividida, de pacientes procedentes da Universidade Estadual Paulista "Júlio de Mesquita Filho" campus de São José dos Campos ­ Instituto de Ciência e Tecnologia. Os mesmos foram divididos em dois grupos estabelecidos, sendo no grupo teste tratamento medicamentoso com Amoxicilina 500 mg, Dexametasona 4 mg e Dipirona 500 mg e no grupo controle os pacientes receberam tratamento com Dexametasona 4 mg e Dipirona 500 mg, sem antibióticoterapia. Os parâmetros utilizados foram edema, trismo e dor, aferidos no pré e pós-operatório, onde foi avaliado os benefícios da antibioticoterapia após a remoção de terceiros molares. Para comparação dos dados foram utilizados escala analógica de dor (EVA), o método de Ustün et al. (2003), e a régua milimetrada, sendo submetidos ao teste T de Student. Diante dos resultados estatísticos obtidos, não foi possível afirmar que a utilização da antibioticoterapia foi benéfica, quando relacionada ao edema, trismo e ao quadro de dor(AU)

Lower third molars semi-included or included removal one of the most performed procedures within oral surgery and inherent to the procedure there is a postoperative inflammatory response. Among the most routine factors to this response are pain, edema and trismus, which can be aggravated in the presence of infections or healing disorders of the surgical wound. However, the use of antibiotics in the postoperative period remains controversial in the literature. Thus, the objective of this randomized clinical trial was to evaluate the postoperative period of 32 third molars, semi-included or included, in a split mouth, of patients from the São Paulo State University "Júlio de Mesquita Filho" campus of São José dos Campos - Instituto of Science and Technology. They were divided into two established groups, in the test group drug treatment with Amoxicillin 500 mg (with ATB), Dexamethasone 4 mg and Dipyrone 500 mg and in the control group patients received treatment with Dexamethasone 4 mg and Dipyrone 500 mg, without antibiotic therapy. (without ATB). The parameters used were edema, trismus and pain, measured before and after the operation, where the benefits of antibiotic therapy after the removal of third molars were evaluated. To compare the data, an analog pain scale (VAS) was used, the method of Ustün et al. (2003), and the millimeter ruler, being submitted to Student's T test. In view of the statistical results obtained, it was not possible to state that the use of antibiotic therapy was beneficial when related to edema, trismus and pain(AU)

Validação para a língua portuguesa do Gothenburg Trismus Questionnaire (GTQ) / Validation of the Portuguese version of the Gothenburg Trismus Questionnaire

Atualmente, o Gothenburg Trismus Questionnaire (GTQ) é o único questionário de qualidade de vida específico sobre trismo. A afecção, definida como restrição à abertura da boca, gera prejuízo a atividades habituais como comer, engolir, falar e fazer a higiene oral, trazendo grande desconforto aos pacientes. A tradução de questionários de qualidade de vida desempenha um importante papel no conhecimento da saúde das populações nos diferentes países. O objetivo do presente estudo é apresentar a validação do GTQ para a língua portuguesa, a fim de permitir sua aplicação efetiva nas populações de idioma português. O GTQ foi validado com sucesso para a língua portuguesa conforme os seguintes passos: Tradução, Retradução (back translation), Adaptação cultural e Revalidação.

Currently, the Gothenburg Trismus Questionnaire (GTQ) is the only quality-of-life questionnaire specific for the assessment of trismus. The disease, characterized by limited mouth opening, impairs usual activities such as eating, swallowing, talking, and performing oral hygiene, causing great discomfort to patients. Translation of quality-of-life questionnaires plays an important role in promoting health awareness in the populations of different countries. This study aimed to validate the Portuguese version of the GTQ to allow its effective application in Portuguesespeaking populations. The Portuguese version of the GTQ was successfully validated through the following steps: translation, back translation, cultural adaptation, and revalidation.

Spontaneous Temporomandibular Joint Dislocation.

Dislocation of the temporomandibular joint (TMJ) is the displacement of the head of the condyle from its normal position in the glenoid fossa. Anterior dislocations are the most common type of TMJ dislocations. Prognathism of the lower jaw, anterior crossbite, and open bite are the classic features in bilateral TMJ dislocations.The treatment of acute TMJ dislocation involves manual reduction with or without general anesthesia. The use of maxillomandibular fixation is reserved for chronic, more complex dislocations. Determining the presence of a predisposing factor is very important in guiding the correct treatment and management for this condition.The authors present a case of acute spontaneous temporomandibular joint dislocation where multiple predisposing factors were recognized, requiring treatment with maxillomandibular fixation after manual reduction.

Long-term functional and esthetic outcomes after fibula free flap reconstruction of the mandible.

BACKGROUND: The goal of this study is to report functional and esthetic outcomes, after fibula free flap (FFF) reconstruction of the mandible for oral cancer, assessed by physicians, nonclinicians, and patients. METHODS: Twenty-five long-term survivors from oral cancer after FFF reconstruction were recalled for head and neck examination by surgeons, for photographs and patient-reported outcomes, using EORTC, QLQ-C30, H&N35, and FACE-Q questionnaires. RESULTS: Physicians reported 64% restoration of functionality compared to normal. Patients reported high scores on QLQ-C30 but lower scores on H&N35. Esthetic scores were reported higher by clinicians than nonclinicians. The decline in function and appearance was attributed to loss of lower dentition, trismus, malocclusion, xerostomia, and tissue atrophy. CONCLUSION: To minimize the decline in function and appearance, immediate dental implants in FFF, better reconstruction of the temporomandibular joint, newer methods of radiotherapy to minimize xerostomia and oral exercises to prevent trismus should be considered.

Prevalence and prediction of trismus in patients with head and neck cancer: A cross-sectional study.

BACKGROUND: Trismus occurs frequently in patients with head and neck cancer. Determining the prevalence and associated factors of trismus would enable prediction of the risk of trismus for future patients. METHODS: Based on maximal mouth opening measurements, we determined the prevalence of trismus in 730 patients with head and neck cancer. Associated factors for trismus were analyzed using univariate analyses and multivariate logistic regression analyses. Based on the regression model, a calculation tool to predict trismus was made. RESULTS: Prevalence of trismus was 23.6%. Factors associated with trismus were: advanced age; partial or full dentition; tumors located at the maxilla; mandible; cheek; major salivary glands; oropharynx; an unknown primary; a free soft tissue transfer after surgery; reirradiation; and chemotherapy. CONCLUSION: About one-fourth of patients with head and neck cancer develop trismus. Based on prevalence and associated factors of trismus, a simple calculation tool predicts the risk of trismus in these patients.

Severe trismus and contraindicated exodontia in a patient with fibrodysplasia ossificans progressiva: case report.

Fibrodysplasia ossificans progressiva is a rare genetic disease of connective tissue in which muscles, ligaments, and tendons ossify either spontaneously or after trauma. Patients can develop physical disabilities and restriction of respiratory function. A patient attended a maxillofacial surgery outpatient clinic with severe trismus and mouth opening limited to 2mm. The risks of intervention were many from both anaesthetic and surgical perspectives, which prevented the extraction of carious teeth. The patient was referred to a special care dentistry team who provided endodontic stabilisation without local anaesthesia. In the case of severe infection, surgical intervention would be challenging to justify.
