Comparative evaluation of buccal pad of fat with and without bovine collagen membrane in the management of oral submucous fibrosis: A prospective clinical study

Nasolabial Flap in the Management of Oral Sub Mucous Fibrosis: A Series of Cases

The objective of this study was to evaluate the outcomes of the nasolabial flap in the management of oral submucous fibrosis (OSMF). The descriptive case series included 75 patients diagnosed with OSMF who underwent surgical intervention under general anesthesia. Preoperative mouth opening measurements were compared with postoperative measurements taken after 2 months. Regarding mouth opening, out of the 75 patients, 4 (5.3%) had unsatisfactory results after treatment, while 22 (29.3%) experienced satisfactory outcomes. The majority of patients, 49 (65.3%), achieved normal mouth opening (more than 30 mm) following the Nasolabial flap procedure. This indicates that the Nasolabial flap yielded favorable results in terms of restoring normal mouth opening and benefiting the patients. Based on the findings of this study, the Nasolabial flap was determined to be a viable surgical option for managing oral submucous fibrosis due to its ease of operation, reliable flap vascularity, and low post-operative complication rate. The only drawback identified was the presence of a surgical scar, which can be addressed through secondary correction procedures.

Efficacy of Collagen Membrane Graft in Intraoral Surgery - An Evaluative Study

Introduction

Bovine-derived collagen membrane is usually and regularly used as a temporary cover or dressing for extraoral wounds and burns. It has wide applications because of its usefulness and biocompatibility. This has provoked us to do a study with the use of collagen membrane even for minor intraoral surgical defects. The aim of this evaluative study was to evaluate the clinical efficacy of collagen membrane in intraoral wounds created by removal of various soft tissue lesions.

Materials and Methods

A total of 25 healthy patients (16 males and 9 females) were taken for this study. This study was confined to secondary defects of the oral mucosa, which occur after excision of premalignant lesions and other conditions, such as benign lesions, reactive proliferations, and incisional biopsy wounds. Only those lesions that were sufficiently large and could not be closed primarily were included in the study.

Results

The results were evaluated on the day of surgery and in the postoperative period. The usefulness of collagen membrane as an intraoral temporary wound dressing material to promote haemostasis, relieve pain, induce granulation, and assist in rapid epithelialization at the wound site and prevent infection, contracture, scarring, and donor-site morbidity was evaluated, and finally, the efficacy of collagen membrane was tested by the use of Chi-square test and P < 0.001, which is a statistically and clinically significant value.

Discussion

Collagen membrane was observed as both biological dressing material and drug carrier. It was found to be a suitable alternative to other graft materials mentioned for the repair of defects in the mucous membrane created by surgical excision of lesions. Therefore, when used judiciously in a controlled clinical situation, collagen membrane is biologically acceptable in nature. It is an alternative to autologous grafts rather than a replacement of other grafts used in the oral cavity.

A Comparative Evaluation between the Use of Buccal Pad of Fat and Bovine Collagen Membrane in the Management of Oral Submucous Fibrosis

Purpose

This study is intended to assess and compare the effectiveness of BFP and BCM as reconstruction materials in treating oral submucous fibrosis (OSMF).

Materials and Methods

This study comprised twenty patients of 20 and 60 years who were clinically diagnosed with OSMF. All patients were subjected to fibrotomy with reconstruction under general anesthesia. In all the patients, following fibrotomy reconstruction was done using the buccal pad of fat on the left and with the collagen membrane on the right. The temporal muscle insertions were released, and coronoidectomy was performed as and when required. Any third molars if present were removed. All patients were feeded for 7 days by Ryle's tube and were on intravenous antibiotics for 5 days. Clinical evaluation was done at periodic intervals of 7, 30, 90, and 180 days postoperatively for mouth opening, burning, pain on mouth opening, and recurrence.

Results

The mean age of patients was 27.3 years. A 12 mm was mean preoperative mouth opening. Intraoperative mouth opening was 37 mm in all the patients and maintained at 36 mm at the 6^th-month postoperative period. No significant difference was observed between both sides pertaining to pain on maximal mouth opening, burning sensation, or postoperative infection. However, there was a significant difference in the time taken for epithelization on both sides.

Conclusion

The results of this study reveal that both Buccal Pad of Fat (BPF) and BCM are viable reconstruction options, but BFP as a reconstruction material exhibited prompt epithelization with the lowest wound contracture.
