RESUMEN
BACKGROUND: Oral submucous fibrosis is a global health concern associated with betel quid use and results in trismus, which can be either primary or secondary in origin. Severe cases often require trismus release with free-flap reconstruction. This study examined longitudinal outcome trends following trismus release and compared the outcomes of patients with primary and secondary oral submucous fibrosis-related trismus. METHODS: We conducted a retrospective cohort study by including patients who underwent trismus release between 2013 and 2022. All procedures were performed by a single surgical team to ensure technique standardisation. We measured the maximum mouth opening, the interincisal distance, perioperatively and 1, 2, 3, 4, 6 and 12 months post-operatively. Data were analysed using generalised estimating equations. RESULTS: A total of 35 patients were included in the study, 17 with primary and 18 with secondary oral submucous fibrosis-related trismus. Initially, patients with primary oral submucous fibrosis-related trismus had greater interincisal distance gains than those with secondary oral submucous fibrosis-related trismus (p = 0.015 and p = 0.025 at 3 and 4 months post-operatively, respectively). However, after 12 months, this initial advantage faded, with comparable interincisal distance improvements in patients with primary and secondary disease, despite the more complex surgical procedures required in secondary cases. CONCLUSION: Surgeons should carefully consider the benefits of trismus release procedures for patients with secondary oral submucous fibrosis-related trismus by recognising the changes in post-operative outcomes.

PURPOSE: Oral submucous fibrosis (OSMF) is a chronic, potentially malignant condition affecting any part of the oral cavity and is prevalent in Southeast Asia and the Indian subcontinent. The aim of this study is to compare the efficacy of buccal fat pad flap with the nasolabial flap in the management of OSMF. METHODS: We systematically compared two commonly used constructive techniques in the management of OSMF: the buccal pad of fat flap and the nasolabial flap. We performed a comprehensive search in four databases for all articles published between 1982 and November 2021. We assessed the risk of bias using the Cochrane Handbook and Newcastle-Ottawa Scale. We used the mean difference (MD) for pooling the data with 95% confidence intervals (CIs) and evaluated the heterogeneity between pooled studies using χ2 and I2 tests. RESULTS: Out of 917 studies, six were included in this review. The meta-analysis significantly favored conventional nasolabial flap over buccal fat pad flap in improving the maximal mouth opening (MD, - 2.52; 95% CI, - 4.44 to - 0.60; P = 0.01; I2 = 0%) after OSMF reconstructive surgery. Conversely, when it comes to esthetic outcomes, these studies favored buccal fat pad flap. CONCLUSION: Our meta-analysis found that nasolabial flap was better than buccal fat pad flap in terms of mouth opening restoration after OSMF reconstructive surgery. Also, the included studies found better results, favoring nasolabial flap over buccal fat pad flap in terms of oral commissural width restoration. Also, these studies reported better outcomes in terms of esthetics, favoring buccal fat pad flap. Further studies with larger sample sizes and different populations/races are needed to confirm our findings.

Severe pain experienced by patients with oral submucous fibrosis (OSMF) compromises their physiotherapy and negatively affects the surgical outcome and the patient's compliance. The main aim of this study was to develop a protocol for pain control in the management of OSMF postoperatively. This was a prospective, parallel with active control, double-arm, triple-blinded, randomised control trial (RCT) with 48 OSMF patients, randomised into two groups - Group A (control, n = 25): received non-opioid analgesics (NSAIDs) and Group B (cases, n = 23): received transdermal fentanyl patches (TFP). Pain and interincisal opening were measured on postoperative days 1, 3, 5, 7, 9, and 15, and on the1st and 3rd postoperative months. Quality of Life (QoL) was assessed preoperatively, on the 15th day postoperatively, and 3rd month postoperatively, and compliance was documented postoperatively on the 9th day. The transdermal fentanyl patch was found to have statistically significantly more effect in controlling severe pain during active mouth opening exercises, and thus significantly increased the patients' compliance. Although there was increased mouth opening and QoL in the fentanyl group, the differences were statistically insignificant. Our study recommends the use of TFP for better pain control and compliance in postoperative OSMF patients.

OBJECTIVE: To evaluate the functional efficacy of two different grafting techniques following the fibrotomy among subjects with oral submucous fibrosis (OSMF). DESIGN: Forty consecutively treated OSMF subjects between 20 and 40 years who had grades 3 and 4a OSMF and mouth opening < 15 mm were included in the present study. All the subjects were randomly divided into two groups. In Group I, all the subjects received a buccal pad of fat sandwiched with a nasolabial flap following fibrotomy. In contrast, Group II subjects received a buccal pad of fat combined with a collagen graft. The effect of two different surgical protocols on mouth opening was evaluated clinically before the surgery (T0) and 1 month (T1), 6 months (T2), and 12 months (T3) after the surgery. RESULTS: In Group I subjects, the mouth opening increased significantly (P < 0.001) from 10.90 ± 1.971 mm at T0 to 34.25 ± 3.127 mm at T1, but reduced marginally to 32.15 ± 3.422 mm at T2, and 31.30 ± 3.358 mm at T3. In Group II, the mouth opening increased significantly (P < 0.001) from 10.85 ± 1.725 mm at T0 to 28.90 ± 3.059 mm, 29.10 ± 2.808 mm, and 28.20 ± 2.285 mm at T1, T2, and T3, respectively. At the end of 12 months of follow-up, the mean value improvement in the mouth opening (T0-T3) was 20.4 ± 3.5 mm and 17.3 ± 2.9 mm in Groups I and II, respectively, and the difference was statistically significant (P = 0.006). CONCLUSION: The buccal pad of fat sandwiched with a nasolabial flap for the reconstruction following fibrotomy had a slightly better beneficial effect on the postoperative mouth opening among OSMF subjects.

BACKGROUND AND OBJECTIVE: Oral submucous fibrosis is a scourge of Southeastern Asia since a long time resulting in significant health and social problems. Mainstay of the treatment is concentrated on attempts to improve mouth opening and relieve the symptoms by medicinal or surgical means. In moderate to severe cases, release of fibrous bands is advocated followed by placement of graft. The present study was conducted to evaluate the use of collagen-silicone bilayer membrane as a mucosal substitute in its management. METHODOLOGY: Study consisted of 12 clinically and histologically proven cases of OSMF. After the incision and release of fibrous bands, a collagen membrane was placed and secured over the raw area by placement of a silicone sheet of adequate thickness. Parameters were assessed pre-operatively, intra-operatively, and post-operatively at 1 week, 1 month, and 3 months. The data was recorded and statistical analysis was done. RESULTS: Pre-operatively, the mean values of inter-incisal opening, cheek flexibility, and width of oral commissure were 16.92, 24.58, and 53.17 mm respectively whereas at 3 months post-operatively, it was 27.67, 26.58, and 55.00 mm, which was statistically significant. No incidence of infection was noted. CONCLUSION: The study concludes that the use of collagen membrane along with silicone sheet can be an alternative to other graft materials in context of reduced donor site morbidity as well as significant increase in inter-incisal opening. However, study with more sample size is needed to assess the long-term efficiency and surgical outcome of this material.

PURPOSE: The involvement of temporalis muscle fibers by oral submucous fibrosis (OSMF) and the procedure of coronoidectomy and temporalis myotomy in the surgical treatment protocol for the disease is a controversy. The primary objective of this study is to evaluate the histopathological changes in temporalis muscle fibers in patients undergoing surgical treatment for OSMF and to authenticate the importance of temporalis myotomy and coronoidectomy in surgical treatment protocol. METHOD: A 3-year prospective study was conducted to assess the histopathological changes in temporalis muscle in surgically treated OSMF cases. The predictor variables were drawn from demographic characteristics (age and gender) etiology, and mouth opening. The outcome variables were histopathological assessment of temporalis muscle fibers for parameters suggestive of degenerative changes and fibrosis changes at cellular level. RESULTS: Out of 56 patients, 30 patients were had surgical intervention. Twenty-eight (93.3%) were male and 2 (6.6%) were female with a ratio of 14:1. Histopathological examination of temporalis muscle fibers revealed hyalinization of muscle fibers in 80% of the patients followed by loss of striation (73.33%), fragmentation (60%), nucleus internalization (33.33%), infiltration of macrophages and other inflammatory cells (20.67%), multiple nuclei (20%), and swollen muscle fibers (6.67%). Mean preoperative mouth opening was 12.4 and post-operatively 41.3 mm on 1-year follow-up and this was stable on further follow-up. CONCLUSION: The results of this study suggest involvement of temporalis muscle with disease itself and the justification for coronoidectomy and temporalis myotomy in the surgical protocol was established.

The aim of this paper was to clinically evaluate the efficacy of the greater palatine pedicled flap (GPPF) for the correction of trismus in oral submucous fibrosis (OSMF). This retrospective study was designed from the patients diagnosed with OSMF who underwent transection of fibrous bands and coverage of the defect in the retromolar trigone (RMT) region using GPPF from 2008-2019. Cases were analysed for preoperative (MOpre-op), and postoperative mouth opening (MOpost-op), secondary healing of the palate, and complications of the procedure. A total of 29 diagnosed cases of OSMF were divided into two groups: group I/stage III (n=13) and group II/stage IV (n=16). The mean (SD) follow up was 29.6 (2.92) months for Group I and 32.4 (3.54) months for Group II. Increase in MOpost-op in group I from 20.0 to 32.92 mm (p=0.0001) and in group II from 6.81 to 26.31 (p=0.0001) was statistically significant. The mean difference of 6.57 mm in MOpre-op and MOpost-op among the groups was also statistically significant (p=0.0001). The mean (SD) duration for secondary healing of the palate was 5 (1) week(s) and flap necrosis was encountered in two cases of group II/stage IV OSMF. We conclude that GPPF is reliable for the treatment of trismus in advanced stages of OSMF.

The purpose of this trial was to study the effect on pain and mouth opening of intramuscular injection of botulinum toxin-A into masticatory muscles following surgical intervention in oral submucous fibrosis (OSMF) cases. Injections of either botulinum toxin A (BTX-A) (study group) or normal saline (control group) were given 2 weeks prior to surgical intervention in OSMF patients, into the bilateral masseter and temporalis muscles. All patients were evaluated for pain and ease of active physiotherapy at 1 week and 1, 3, and 6 months after surgery using a numerical rating scale and appropriate questionnaires, with comparisons made between the study and control group patients. Electromyographic studies of the masticator muscles were also carried out in all patients before injection, and at 1 month and 6 months after injection. 20 OSMF patients were equally divided into study and control groups (n = 10 each). At 1, 3, and 6 months after surgery, the study group patients showed significantly greater decreases in pain (p-values of 0.007, 0.001, and 0.005, respectively) and greater ease in physiotherapy compared with the control group. EMG recordings of masticator muscles showed a transient drop in microvolt value in the study group 1 month after injection, unlike the control group recordings. It was concluded that preoperative BTX-A injection was a good addition to surgical therapy in the patient group.

PURPOSE: In the management protocol of the oral submucous fibrosis (OSMF), multiple studies have advocated that an additional step of coronoidectomy or coronoidotomy helps achieve better and more consistent postoperative results. But, there are no studies that validate if one has an advantage over the other. This study aimed to compare the outcome of the coronoidectomy with coronoidotomy for OSMF cases. METHODS: A randomized controlled trial was designed in patients with OSMF requiring operative intervention. Patients were randomized into 2 groups based on a computer-generated randomization table: group I coronoidectomy and group II coronoidotomy. The primary predictor variables were the 2 different adjunct surgical steps - coronoidectomy and coronoidotomy. The primary outcome variable was the postoperative maximum incisal opening (MIO). Secondary outcome variables were duration of surgery and blood loss. RESULTS: The study sample was composed of 32 patients (16 each group). Both the groups were comparable in terms of demographic profile. The MIO after surgery was comparable throughout the study between the groups. Repeated measures analysis of variance for comparison of mouth opening within the group showed that there was a significant improvement in postoperative MIO in both the groups (group I P value <.001 and group II P value 0.004). A statistically significant difference was found in the duration of the surgery (3.5 ± 0.73 hours vs 2.06 ± 0.87 hours) and blood loss (393 .75 ± 278.6 mL vs 90.62 ± 58.36 mL) with the shorter time and less blood loss in coronoidotomy compared with coronoidectomy. All these cases were followed for 1 year. CONCLUSIONS: Coronoidotomy as an adjunctive treatment in OSMF provides comparable treatment outcome in terms of MIO compared with coronoidectomy with the added advantage of shorter operating time and less blood loss.

Abstract: Focal fibrous hyperplasia (FFH) is an oral mucosal localized non-neoplastic enlargement representing a reaction to chronic local irritations or injuries. The purpose of this report is to describe the management of an asymptomatic fibrotic lesion located in the tongue, in a preschooler boy. A 7-year-6-month old boy attended our clinic for the evaluation of an exophytic pedunculated tumor-like round mass located in the dorsal surface of the tongue. Based on the initial examination and the natural history of the lesion, the presumptive clinical diagnosis determined an irritation FFH. The lesion was surgically excised with a diode laser device, and the postoperative period evolution occurred without any complication. The appropriate treatment of FFH in children initially consists of the removal of local irritant factors. Excellent oral hygiene maintenance and close follow-up care are strongly suggested. Surgical excision is the most frequent modality for persistent lesions. Early diagnosis and proper management of FFH can reduce the risk of future recurrences or complications.
Resumen: La hiperplasia fibrosa focal (HFF) es un agrandamiento no neoplásico localizado en la mucosa oral que representa una reacción a irritaciones o lesiones locales crónicas. El propósito de este informe es describir el tratamiento de una lesión fibrótica asintomática ubicada en la lengua, en un niño en edad preescolar. Un niño de 7 años y 6 meses de edad asistió a nuestra clínica para la evaluación de una masa redonda exofítica y pedunculada con forma de tumor ubicada en la superficie dorsal de la lengua. Basado en el examen inicial y la historia natural de la lesión, el diagnóstico clínico presuntivo determinó una irritación HFF. La lesión se extirpó quirúrgicamente con un láser de diodo, y la evolución en el período postoperatorio se produjo sin ninguna complicación. El tratamiento apropiado de HFF en niños inicialmente consiste en la eliminación de factores irritantes locales. Se recomienda un excelente mantenimiento de la higiene bucal y una estrecha atención de seguimiento. La escisión quirúrgica es la modalidad más frecuente para lesiones persistentes. El diagnóstico temprano y el manejo adecuado de la HFF pueden reducir el riesgo de futuras recurrencias o complicaciones.

The aim of the study was to evaluate the effectiveness of seagull-shaped nasolabial flap (NLF) along with adjunctive short-term oral pentoxifylline in the surgical reconstruction of oral sub mucous fibrosis (OSMF) following fibrotomy. We retrospectively evaluated 18 patients with grade IV oral sub mucous fibrosis treated by NLF. There were 3 females and 15 males. All patients were classified as stage IV OSMF with a mean preoperative mouth opening of 8.11±3.38mm. Postoperatively, patients were administered 400mg of pentoxifylline (PTX) thrice daily for 3 months. Patients were followed up at one month, six months and one year. Mouth opening, presence or absence of malignant transformation, relapse and complications were recorded at each follow-up. We found statistically significant increase in mouth opening from 8.11±3.3 to 37.67±3.74 in the postoperative period. The complications associated with NLF were very minimal. The PTX was well tolerated by all the patients. There was no incidence of relapse or rebound fibrosis seen in our series. To the best of our knowledge, this is the first time that oral pentoxifylline has been administered along with surgical treatment of oral submucous fibrosis to prevent relapse. The use of oral PTX as an adjunct along with surgical reconstruction in OSMF improves mouth opening, reduces burning sensation and relapse.

The aim of our study was to evaluate the effectiveness of buccal fat pad (BFP) in the management of oral submucous fibrosis (OSMF). Retrospective records of 30 patients of OSMF treated with BFP with atleast a year of follow-up were analyzed. Patients were divided into groups based on the stages of OSMF. Surgical management consisted of resection of fibrous bands, bilateral temporalis myotomy, and coronoidectomy followed by grafting with BFP. There were 17 patients of stage III (mouth opening 16-25 mm) and 13 patients of stage IV OSMF (mouth opening less than 16 mm). The mean mouth opening of stage III group pre-operatively was 19.94 ± 2.19 mm which increased to a mean of 35.12 ± 5.69 mm (p < 0.0001). For patients with stage IV OSMF, the mouth opening increased from a pre-operative of 10.23 ± 4.07 mm to a post-operative of 31.46 ± 6.78 mm (p < 0.0001). No intra-operative complications were noted in any patient. Relapse was seen in 1 patient (5.8%) of stage III while 3 patients (23.07%) had relapse in stage IV group. Our results indicate that BFP is a good flap owing to its benefits which are easy to harvest and entails minimal morbidity for management of OSMF.

To evaluate the efficacy of laser fibrotomy in patients with oral submucous fibrosis (OSMF) and also to correlate the habit variables causing OSMF. Thirty patients diagnosed clinically and histopathologically with OSMF were included in the study. Laser fibrotomy was done under local anesthesia using Zolar diode laser (980 nm frequency) at 2-W power in contact mode with fibro-optic cutting tip. The patients were advised to practice mouth-opening exercises rigorously, and topical corticosteroid was given for burning sensation and pain for 6 months. Pre- and post-treatment comparison of mouth opening, burning sensation, tongue protrusion, and cheek flexibility was analyzed after a follow-up period of 9 months. After a follow-up period of 9 months from the surgical intervention, the mean value of difference in pre- and post-treatment of VAS score, mouth opening, and tongue protrusion was found to be 3.3 ± 2.1, 7.7 ± 5.1, 1.6 ± 2.7, and 0.38 ± 0.61 respectively. Using the Wilcoxon signed rank test, all the above difference in mean was found to be significant with p value < 0.05. With above suggested significant results, lasers can provide an alternative and better means for surgical fibrotomy, relieving trismus in moderate OSMF as they are minimally invasive, cause less hemorrhage, and have faster healing and minimal surgical site scaring and relapse.

AIM OF THE STUDY: The aim of this study was to correlate the clinical staging (clinical severity) with the histopathological staging (histopathological changes) of oral submucous fibrosis (OSF) patients, which would further assist the clinicians to formulate a definite treatment plan. MATERIALS AND METHODS: The study group consisted of 50 subjects who were clinically and histologically diagnosed as OSF. Detailed information was gathered in a pretested proforma with emphasis on the various addictions. The clinical findings were noted; punch biopsy was performed followed by histological examination. Clinical and histological staging were divided into four stages, as Stages I-IV according to Khanna and Andrade classification. RESULTS: The 50 subjects were in the age range of 18-70 years, of which 20 patients were in clinical Group III, 15 were in histopathological stage III, 2, 1, and 2 in Stage II, Stage I, and Stage IV, respectively, out of 5 patients in clinical Group IV, 4 were in histopathological staging IV and 1 was in Stage III, out of 5 patients in clinical Group I, 3 and 2 were in histologic Stages II and I, respectively. Statistical analysis with Chi-square test showed high significance with P < 0.001. CONCLUSION: The correlation of clinical and histopathological staging was found to be highly significant, thus suggesting that the subject with clinically advanced OSF had extensive fibrosis histologically.

PURPOSE: Various surgical modalities have been advocated for the soft tissue reconstruction of oral cavity with variable results. This prospective study evaluates the utility of platysma myocutaneous flap (PMF) in the reconstruction of surgical defects followed by treatment of oral submucous fibrosis (OSMF) and oral squamous cell carcinoma (OSCC) in terms of healing and functional outcomes. METHODS: In this prospective study, 47 patients with OSMF and 15 of OSCC were evaluated and selected for PMF reconstruction. OSCC was selected under T1N0M0 category only. Patients were operated under general anaesthesia followed by PMF grafting. In OSCC, ipsilateral and for OSMF, bilateral PMF was used. RESULTS: In 47 patients treated for OSMF, 46 were male and 1 female while 15 cases of OSCC, 10 were male and 5 females aged between 18 and 44 years. Intraoperative mouth opening was achieved up to 48 mm in OSMF followed by 42.5 mm postoperatively after 2 years. However, uneventful healing and acceptable scar on cervical region was noted in all the cases including OSCC. In OSMF, three cases of dehiscence, four partial necrosis at end of flap and in OSCC one case shows skin loss at flap and two partial necrosis at tip of flap and extraoral localised abscess at ipsilateral donor site in one case was noted. An uneventful healing, anatomical form and functional results were restored with acceptable scarring at donor site without any evidence of difficulty in neck movements were observed. CONCLUSION: The PMF is simple, versatile and could be valued as a reconstructive alternative, with interesting visual qualities. It is a good therapeutic alternative tool for reconstruction of the buccal mucosa, especially for small- and medium-sized defects between 2 and 4 cm2 of the oral cavity.

PURPOSE: The aim of this study was to compare the efficacy of locally available nasolabial and buccal fat pad flaps for increasing postoperative mouth opening in the reconstruction of the defect created after fiberotomy in surgically treated cases of oral submucous fibrosis (OSMF). MATERIALS AND METHODS: Of 32 patients selected for the study, 21 patients underwent closure of the surgical defect using the buccal fat pad (group 1) and 11 patients underwent closure of the surgical defect using a nasolabial flap (group 2). Histologically proven cases of OSMF with a mouth opening no larger than 25 mm were included in the study. Patients in groups 1 and 2 were evaluated at regular intervals and mouth opening was documented preoperatively, intraoperatively, and at 3 and 6 months of follow-up. The results were analyzed by paired and unpaired t tests. RESULTS: In groups 1 and 2, mouth opening differed substantially at all periods of follow-up from preoperative values. At 3-month follow-up, mean mouth opening increased to 32.41 mm in group 2 compared with 30.47 in group 1. No relevant difference was observed in mouth opening between groups 1 and 2 at the end of 6 months. The effective increase in mouth opening at the end of 6 months compared with the preoperative value was statistically different in group 2 (mean increase, 24.2 mm) compared with group 1 (mean increase, 19.2 mm). CONCLUSION: Nasolabial flaps are a good option for the coverage of surgically treated defects in OSMF compared with the buccal fat pad.

Oral cancers associated with submucosal fibrosis-induced trismus are common. They may affect the patients' quality of life, cause nutritional deficits, and interfere with postoperative cancer surveillance. In such cases, locating desirable recipient vessels in the head and neck can be difficult. This report presents a 47-year-old man with severe trismus caused by recurrent head and neck cancer, who had received multiple free-flap reconstructions after cancer ablation. Reconstruction was successfully achieved for the bilateral defects and releasing the trismus by using simultaneous double free radial forearm flaps as a chained flow-through pattern with one residual recipient vessel combined with the bilateral myotomy of the medial pterygoid and masseter muscles, and coronoidectomy. Both flaps survived without any postoperative complication. The maximal mouth opening measured by interincisal distance was 38 mm intraoperative and 32 mm during the 3-year follow-up period. This approach may be an effective option for releasing trismus when recipient vessels are lacking.

Early management of premalignant lesions like oral submucous fibrosis cannot be underestimated in context of prevention and control of oral malignancies. Soft tissue reconstruction of the oral cavity and face is a complex undertaking. Several flaps local and distant as well as microvascular are available, each with their pros and cons. Microvascular free flaps lay a considerable burden on resources, expertise, increased operating time, and logistics. Simple and technically reproducible alternatives are needed to tackle these issues, more so in developing countries like ours. Submental flap is based on a large branch of the facial artery and was initially described in 1993 by Martin et al as an excellent option in head and neck reconstruction. We describe innovative modification of the submental flap based on concept of bilateral presence of facial and submental vasculature and thus can be used for bilateral cheek reconstruction. We use pedicled bilateral submental flap (BSF) by dividing the oval skin paddle obliquely, maintaining needed length. The best use of the BSF is in reconstruction of cheek defect, after surgical release of grade IV oral submucous fibrosis, a debilitating affliction commonly affecting young productive adults and seen in Indian subcontinent. The technique was used successfully in 20cases with minor complications.
