Technique of Dual Distraction for Correction of Unilateral Temporomandibular Joint Ankylosis With Facial Asymmetry: A Case Series.

PURPOSE: Temporomandibular joint (TMJ) ankylosis, not only results in joint hypomobility, but also causes considerable facial deformity. Its unilateral variant can cause facial asymmetry, leading to major psychosocial effects on the individual. PATIENTS AND METHODS: We present the cases of 7 patients with unilateral TMJ ankylosis and facial asymmetry of various grades who have been treated using gap arthroplasty and simultaneous dual distraction. Considerable debate has surrounded the sequencing of TMJ release and distraction osteogenesis; however, the simultaneous approach has recently become popular. The use of a single distractor simultaneously with TMJ release has been widely reported. However, one disadvantage with this technique is that the proximal condylar segment remains unstable. Dual distraction is a newer technique which we have proposed as a single-stage approach for the correction of TMJ ankylosis and facial asymmetry and to address the problems resulting from the use of a single distractor. RESULTS: After treatment, all the patients showed a mouth opening ranging from 35 to 50 mm and satisfactory facial symmetry. CONCLUSIONS: Dual distraction is a promising technique in the correction of facial asymmetry. However, further studies with adequate statistical analysis and larger sample size are required.

Evaluating the use of octyl-2-cyanoacrylate in unilateral cleft lip repair.

BACKGROUND: Facial cosmetic results are one of the most concerning issues for the parents who get their children operated for cleft lip. Moreover, the postoperative care of the surgical site, the discomfort associated with the suture removal, and additional visit for suture removal are other reasons which encourages one to use any new technologies that may replace the need for suture placement. In this study, we used octyl-2-cyanoacrylate, a tissue adhesive which offers a viable alternative to traditional techniques without compromising optimal wound closure. OBJECTIVE: To perform a comprehensive comparison of the outcomes from the use of Dermabond in patients undergoing primary repair of congenital cleft lip ± palate anomalies. MATERIALS AND METHODS: Twenty patients, in the age group of 3-18 months were treated surgically for unilateral cleft lip deformity using Millard rotation-advancement flap. Pre- and post-operative photographs of the patients were taken at 1 week, 2 week, 1 month, 6 months, and 1 year postoperatively and were evaluated using Vancouver scar scale which was given by Sullivan in 1990. Paired t-test was used for statistical analysis. RESULTS: Increased vascularity (hyperemia) was seen in the 1st and 2nd week in 35% and 30% patients, respectively which gradually reduced to normal in subsequent follow-ups. The scar was flat in 85% of patients in 1st week, and the number decreased to 10% at the end of 1 year. No wound dehiscence was found in any patients. Statistical analysis showed that among all the follow-ups, only the difference between the first and second follow-ups. Comparison of the results of 1 week with all other follow-ups yielded no significant results. CONCLUSION: Octyl-2-cyanoacrylate can be used for cleft lip closure effectively. The procedure is relatively painless and quick. Added to this are benefits of protection from wound infection since the material is bacteriostatic.

6-0 nylon versus 6-0 vicryl rapide in chieloplasty.

CONTEXT: Facial cosmetic result is one of the most concerning issues for the parents who get their children operated for cleft lip. Moreover, the discomfort associated with the suture removal encourages one to use any new technology that may replace the need for suture placement. The type of suture material used in surgery has been a long-standing debate among surgeons. In this study, we compared rapidly absorbable suture material (Vicryl Rapide™) with nonabsorbable suture material (nylon). AIMS: The aim of this study is to compare the appearance and course of scar, wound infection, and patient's parent perception using Vicryl Rapide and nylon in nonsyndromic congenital cleft lip repair. SETTINGS AND DESIGN: This was a randomized prospective controlled clinical trial. MATERIALS AND METHODS: Twenty patients, in the age group of 3-18 months treated for unilateral congenital cleft lip deformity, were included and randomly allocated to two groups with ten patients each. Skin suturing was done with 6-0 polyamide and 6-0 irradiated polyglactin in Groups A and B, respectively. Patients were evaluated at 1 week, 1, 3, 6 months, and 1 year postoperatively in person by the observer as well as by the patient's parent. STATISTICAL ANALYSIS USED: Descriptive statistical analysis was done using SPSS 20, and Student's t-test was applied. RESULTS: It was found that Vicryl Rapide showed more hypopigmented scars and raised scars than nylon at the end of 1 year though overall appearance was comparable between the groups. CONCLUSIONS: Vicryl Rapide showed poorer cosmetic outcomes in terms of height and pigmentation of car as compared to nylon suture of same thickness. However, since scars tend to improve with time, a bigger sample size and a longer follow-up are required to generalize this statement.

Assessment of facial nerve injury with "House and Brackmann facial nerve grading system" in patients of temporomandibular joint ankylosis operated using deep subfascial approach.

BACKGROUND: Preservation of the functional integrity of the facial nerve (FN) is a critical measure of success in temporomandibular joint (TMJ) surgery. In spite of the development of a myriad of surgical approaches to the TMJ, FN remains at risk. The deep subfascial approach provides an additional layer of protection (the deep layer of the temporalis fascia and the superficial temporal fat pad) to the temporal and zygomatic branches of the FN and thus, is the safest method to avoid FN injury. OBJECTIVES: To assess FN injury following TMJ surgery using deep subfascial approach and measuring it on House and Brackman facial nerve grading system (HBFNGS). MATERIALS AND METHODS: Twenty TMJs in 18 patients were operated for TMJ ankylosis, using "the deep subfascial approach." FN function was assessed postoperatively at 24 h, 1 week, 1 month, 3 months, 6 months using HBFNGS. Statistical analysis was done using SPSS 16.0. RESULTS: Of 20 surgical sites 3 sites showed Grade III (moderate) FN injury and 17 sites showed Grade II (mild) FN injury at 24 h. The condition improved with time with full recovery of FN at all surgical sites at 6 months. CONCLUSION: The deep subfascial approach has a distinct advantage over the conventional approaches when dissecting the temporal region and is the safest method to avoid injury to FN.
