Congenital Upper Lip Sinus.

Congenital upper lip sinus (CULS) is an extremely rare anomaly. The aim of the study is to present a new case and compile the present knowledge of CULS to help foster a deeper understanding of this disease. A 9-year-old girl with a midline CULS, a prolonged maxillary labial frenulum, and a palatal epulis is presented. Thirty-nine papers met the eligibility criteria and 45 cases were included in the systematic review. CULS shows typical clinical and pathologic characteristics. It tends to occur at the midline region horizontally (n=35; 78%) and the upper part of the white lip (n=23; 51%) vertically. No ethnic predilection is found, but it tends to show a female predilection (n=28; 62%). Twenty-six cases (58%) are symptomatic. Thirteen cases (29%) are accompanied by other maxillofacial defects. In all cases, the sinus was lined with stratified squamous epithelium. The etiology remains unknown but 3 theories have been put forward: the fusion theory, the merging theory, and the invagination theory. The authors believe that CULS shows homogeneity with cleft lip to some extent and maybe a microform of it. Primary treatment is surgical excision and the prognosis is favorable, with no complications or recurrence.

Maxillary labial frenectomy: a randomized, controlled comparative study of two blue (445 nm) and infrared (980 nm) diode lasers versus surgical scalpel.

BACKGROUND: This study aimed to compare the intra and postoperative complications of frenectomy procedure with a surgical scalpel versus 445 nm and 980 nm diode lasers. METHODS: This randomized controlled clinical trial was conducted on 174 patients requiring maxillary labial frenectomy. After completion of fixed orthodontic treatment and primary closure of maxillary diastema, the patients were randomly assigned into three groups (n = 58): group 1 (frenectomy via 445 nm diode laser, continuous-wave, 1.5 W), group 2 (frenectomy via 980 nm laser, continuous-wave, 1.7 W), and control group (V-Y plasty technique via scalpel). Intra-operative bleeding, discomfort in chewing and speaking, pain, and tissue healing were compared among the groups immediately, at 7 and 30 days postoperatively using the Kruskal-Wallis, Mann-Whitney, and Chi-square tests. RESULTS: Pain scores were significantly lower in group 1 compared to group 2 (immediately and day 7, P < 0.05). Significant faster tissue healing at days 7 and 30 were observed in group 1 compared to group 2 (P < 0.05). Group 1 was superior to the control group regarding lower intraoperative bleeding, discomfort in chewing and speaking (immediately and day 7), lower pain (immediately and day 7), and tissue healing (day 7) (P < 0.05 for all). Group 2 was significantly superior to the control group in lower intraoperative bleeding, discomfort in chewing and speaking (immediately and day 7), and better tissue healing (day 7) (P < 0.05 for all). CONCLUSIONS: In conclusion, diode laser frenectomy resulted in significantly lower intra and postoperative complications compared to the scalpel. Moreover, 445 nm diode laser showed significantly superior effects compared to 980 nm diode laser. TRIAL REGISTRATION: The study protocol was registered on 29.10.2022 at the Iranian Registry of Clinical Trials ( www.irct.ir ) (registration number: IRCT20220630055326N1).

Surgical methods of managing the upper lip frenulum - a literature review.

The upper lip frenulum with an overgrown structure or improper attachment is a common cause of hygienic, orthodontic, or prosthetic issues that prompt surgical intervention. The following article presents the surgical methods for the elimination of the overgrown frenulum, discussing and comparing them. Commonly used and described in the literature methods for surgical correction of the upper lip frenulum include frenulectomy, frenuloplasty, and laser excision of the frenulum. The article presents, discusses, and compares the methods of surgical correction of the upper lip frenulum, highlighting the advantages and disadvantages of each procedure. According to researchers, when comparing methods using a scalpel, Z-frenuloplasty is characterized by the lowest recurrence rate and consequently the highest effectiveness in eliminating the problem of an overgrown frenulum. The article also outlines several advantages of using laser methods (diode laser, CO2 laser), such as the elimination of bleeding, reduced postoperative pain reported by patients, and the lack of need for suturing the postoperative wound. Each case depends on a thorough clinical examination of the patient, identifying the specific problem, making an accurate diagnosis, and ultimately adjusting the choice of one of the methods to the individual conditions and medical issue of the patient.

Upper-lip laser frenectomy with a diode laser in a pediatric patient: a case report.

The case report aims to describe the parameters of performing upper labial frenectomy with the use of diode laser beams without infiltrated local anaesthesia. A 6-year-old patient was referred by the orthodontist for assessment of the upper anterior labial frenum. The dental treatment plan reported only the presence of caries on deciduous teeth and seals on the first permanent molars. The clinical examination reported the presence of a high attachments of labial frenum with a pathologically attachment and the presence of a diastema supports this theory. The laser used to remove the frenulum was a diode laser used with a wavelength of 980 nm with 320 microns of fiber in contact with a power of 2.0 W in continuous wave mode. The clinical examination showed an acceptable healing by secondary intention of the wound and the initial functional recovery of a physiological upper lip movements. The patient reported that the procedure was well tolerated. The diode laser can be used with good result for the removal of pathological frenum. The diode laser can be used in pediatric dentistry because of its application, adequate coagulation, no need for sutures and less inflammation and pain.

Effect of preventive closure of the frenulum after endoscopic papillectomy: A prospective pilot study.

BACKGROUND AND AIM: The usefulness of preventive closure of the frenulum after endoscopic papillectomy (EP) could reduce bleeding. The feasibility and safety of clipping were evaluated in this prospective pilot study. METHODS: This study involved 40 consecutive patients who underwent preventive closure of the frenulum by clipping just after EP. The outcome data were compared with those of the previous 40 patients in whom no preemptive closure had been performed (no-closure group) (UMIN000014783). Additionally, the bleeding sites were examined. RESULTS: The clipping procedure was successful in all patients. As compared to the no-closure group, the rate of bleeding (P = 0.026) and period of hospital stay (P < 0.001) were significantly reduced in the closure group. There was no difference in the procedure time between the two groups. Furthermore, the incidence rates of pancreatitis and perforation were comparable in the two groups. The bleeding was noted in the frenulum area rather than at any other site in 90.9% of cases. CONCLUSION: Preventive closure of the frenulum after EP is an effective, safe, rational, and economical method to reduce the incidence of delayed bleeding, without prolonging the procedure time or increasing the risk of post-procedure pancreatitis perforation.

Laser labial frenectomy: a simplified and predictable technique. Retrospective clinical study.

AIM: Anomalous maxillary median labial frenum may be associated with undesired effects such as persistence of diastema between anterior teeth or traction of marginal gingiva. The aim of this study was to propose a surgical frenum repositioning technique that is minimally invasive, safe, easy, reproducible, and predictable. Another objective of the study was to identify clinical scenarios that could have indication for labial frenectomy associated with early orthodontic therapy, so as to justify early frenum repositioning in children. A retrospective assessment of clinical outcomes of this technique is described. MATERIALS AND METHODS: A total of 20 frenectomies were performed on children aged 8 to 10 years. Frenectomies were performed with Er:YAG laser set at 150mJ 2.25-3.0W and 15-20 pulse per second, with water spray. Recall visits were done at 7, 21 and 90 days and 1, 2, 3 and 4 years. RESULTS: At post-operative visits, all patients reported no post-operative pain or minimal discomfort. None experienced post-operative bleeding at a distance of few hours. All patients reported that the procedure was well tolerated and "acceptable". No recurrences occurred 4 years after frenectomy. CONCLUSION: The Er:YAG laser used in this study allowed considerable reduction of the operating time, reducing the amount of local anaesthetic used as well as avoiding surgical sutures. The surgical design and technique also minimised post-operative discomfort and complications resulting in stable healing overtime, making the procedure fully accepted by children.

A modified frenectomy technique: a new surgical approach.

The frenum is a mucosal fold that attaches the lips or cheeks to the alveolar mucosa, gingiva, and underlying periosteum. Consequences of an abnormal frenal attachment include gingival recession, decreased vestibular depth, decreased range of lip movement, and involvement of interdental papilla, causing a diastema. Several methods to eliminate ectopic frenal attachments have been suggested, including frenectomy (elimination) and frenotomy (repositioning). This case report describes the use of a modified frenectomy technique in a 15-year-old girl with excess gingiva between the maxillary central incisors, which exhibited a 3-mm diastema. First, a semilunar primary incision was made in the palatal surface at a 5-mm distance from the tip of the papilla. Next, sulcular incisions were made around the tooth, and the papilla was transposed to the buccal via a papilla preservation flap. After complete elimination of frenal attachments in the bone, the flap was repositioned and sutured to the palatal surface. Afterward, the frenum was classically cut and sutured. Through this approach, the position of the frenum was changed apically without invading the papilla. At the 3-month follow-up, it was found that the modified technique (combination of papilla preservation flap and frenotomy) had minimized the surgical scar on the buccal surface, preserved the papilla, and yielded optimal esthetic results.

All Tied Up! Influences of Oral Frenulae on Breastfeeding and their Recommended Management Strategies.

BACKGROUND: Recently, there has been an increased awareness of the role of the labial and lingual frenulae on a neonate's ability to latch and breastfeed efficiently. This critical review explores the (i) oral physiology of a baby nursing (ii) factors that can decrease a baby's ability to nurse efficiently, the problems these cause and their management and the (iii) relation between poor nursing efficacy and the risk of early childhood caries (ECC) Study design: An expansive search of the literature was performed using four electronic databases. RESULTS AND CONCLUSIONS: Most studies assessing the role of labial and lingual frenulae on breastfeeding were of a low quality. The relation between ECC and poor nursing efficacy was found to be largely speculative. Hence, the results of these studies should be interpreted with caution. Despite the limited quality and external validity of the current evidence, in cases where breastfeeding difficulties are identified, surgical management of labial or lingual frenulae may provide some subjective improvements in breastfeeding outcome.

Evaluation of patient perceptions after frenectomy operations: A comparison of neodymium-doped yttrium aluminum garnet laser and conventional techniques in the same patients.

BACKGROUND: The aim of the present study was to compare the level of postoperative discomfort between labial frenectomy done by neodymium-doped yttrium aluminum garnet (Nd: YAG) laser and the conventional technique and evaluate the differences in the levels of postoperative pain and functional complications such as eating and speaking between these two methods. MATERIALS AND METHODS: Forty patients requiring labial frenectomy in both jaws were included in the study. One side of each patient was treated with laser, whereas the other side was treated with the conventional technique and all surgeries were performed by the same surgeon. Postoperative pain and functional complications were evaluated for each patient and recorded using a visual analog scale on the operation day and postoperative 1, 3, 7 and 10 days. RESULTS: The results indicated that patients treated with the Nd: YAG laser had lower levels of postoperative pain and were more comfortable while chewing and speaking at the operation day and postoperative 1st day (P < 0.05). CONCLUSION: The results suggest that Nd: YAG laser application during oral soft-tissue surgery provides better patient perceptions and less postoperative pain compared to conventional surgery.

Surgically Assisted Orthodontics: Use of Piezocision in a Case of Oligodontia to Accelerate the Rate of Tooth Movement.

Conventionally the use of surgical assisted tooth movement is to hasten orthodontic tooth movement. In this article, a case of 13 year-old male with oligodontia has been described in whom piezocision has been used to improve bone turnover and remodeling in long standing edentulous spaces which have less medullary bone and more cortical bone.

Minimally invasive treatment of soft tissue deficiency around an implant-supported restoration in the esthetic zone: modified VISTA technique case report.

The horizontal and vertical soft tissue dimension around an implant-supported restoration in the maxillary anterior is one of the determining factors for achieving an esthetic result. In this case report, the patient presented with a deficiency in both dimensions around a single-tooth implanted-supported restoration in the anterior maxilla. The soft tissue defects were augmented with a connective tissue graft that was placed underneath the buccal peri-implant tissue using a frenum access incision and a supraperiosteal tunneling approach (modified vestibular Incision supraperiosteal tunnel access [VISTA] technique). This novel technique resulted in an increase in tissue height and width, which suggests its potential use around implant-supported restorations.

Unexpected soft tissue changes in response to root coverage using an acellular dermal matrix allograft: 12­year follow up.

A woman undergoing orthodontic treatment presented with recession and reduced keratinized gingiva on teeth 31 and 41. The patient declined creation of a donor site for conventional autogenous connective soft tissue grafting and opted for an acellular dermal matrix soft tissue substitute for root coverage. Orthodontic treatment followed, and the patient returned for orthognatic surgery after 12 years. Long-term follow up revealed that root coverage remained stable over time and creeping attachment on both teeth was observed. Unexpectedly, an increase in the width of keratinized gingiva was observed. No adverse effects of orthodontic treatment carried out after grafting were observed.

Excessive gingival display: treatment by a modified lip repositioning technique.

AIM: The objective of this prospective study was to investigate outcomes of a lip repositioning technique for the treatment of excessive gingival display. MATERIALS AND METHODS: Thirteen consecutively treated patients with excessive gingival display were treated with a modified lip repositioning technique. Treatment consisted of the removal of two strips of mucosa, bilaterally to the maxillary labial frenum and coronal repositioning of the new mucosal margin. The clinical dimensions of gingival display, upper lip and vermillion length were measured at baseline, 3 and 6 months post-operatively. Subjects completed surveys to evaluate satisfaction with outcomes. RESULTS: The baseline gingival display of 5.8 ± 2.1 mm significantly decreased to 1.4 ± 1.0 mm at 3 months (p < 0.0001) and was maintained until 6 months (1.3 ± 1.6 mm). The reduction in gingival display strongly correlated to the combined change in upper lip and vermillion length (r(2)  = 0.60, p = 0.0018). Subjects were satisfied with their smile after surgery and would likely choose to undergo the procedure again (92%). The worst part of undergoing the procedure was the discomfort or the inability to move the lip during the early healing (69%). CONCLUSION: Treatment of excessive gingival display by means of a modified lip repositioning technique results in high level of patient satisfaction and predictable outcomes that are stable in the short term.

Cutting and coagulation during intraoral soft tissue surgery using Er: YAG laser.

AIM: To find the optimal techniques and parameters that enables Er:YAG laser to be used successfully for small intraoral soft tissue interventions, in respect to its cutting and coagulation abilities. CASE REPORT: In vitro pre-tests: 4 different Er:YAG laser units and one CO2 unit as the control were used for incision and coagulation on porcine lower jaws and optimal parameters were established for each type of intervention and each laser unit: energy, frequency, type, pulse duration and distance. CASE SERIES: 3 different types of intervention using Er:YAG units are presented: crown lengthening, gingivoplasty and maxillary labial frenectomy with parameters found in the in vitro pre-tests. RESULTS: The results showed a great decrease of the EMG activity of masseter and anterior temporalis muscles. Moreover, the height and width of the chewing cycles in the frontal plane increased after therapy. CONCLUSION: Er:YAG is able to provide good cutting and coagulation effects on soft tissues. Specific parameters have to be defined for each laser unit in order to obtain the desired effect. Reduced or absent water spray, defocused light beam, local anaesthesia and the most effective use of long pulses are methods to obtain optimal coagulation and bleeding control.

Modified frenectomy: a review of 3 cases with concerns for esthetics.

The maxillary labial frenum is a normal anatomical structure in the oral cavity. An abnormal labial frenum causes localized gingival recession and midline diastema, both of which can interfere with oral hygiene procedures, and eventually affect esthetics. When the frenum maintains its high papillary attachment, frenectomy is the treatment of choice. Though this technique has undergone many modifications, the zone of attachment and esthetics in the anterior maxillary region have been neglected. This article highlights a new frenectomy technique that results in good esthetics, excellent color match, gain in attached gingiva, and healing by primary intention at the site of thick, extensive abnormal frena.

Laser Surgical Approach of Upper Labial Frenulum: A Systematic Review.

An abnormal and hypertrophied upper labial frenulum (ULF) can cause diastemas, gingival recession, eruption abnormalities, and the onset of carious and periodontal problems in the upper central incisors, as well as aesthetic and functional disorders of the upper lip. The goal of this investigation is to review the evidence on the surgical techniques that are currently available for treating ULF in order to identify the best approach. PubMed, Scopus, Cochrane Library, and Embase were searched for papers that matched our topic from 13 November 2012 up to 22 November 2022 using the following Boolean keywords: "frenulum" and "surgery*". A total of eight articles were selected for the purpose of the review. ULF can be surgically treated using either traditional scalpel surgery or laser surgery. The latter is the better option due to its intra- and post-operative benefits for both the patients and the clinicians, in terms of faster healing, fewer side effects and discomfort, and greater patient compliance. However, a higher learning curve is required for this technique, especially to calibrate the appropriate power of the laser. To date, it is not possible to identify which type of laser achieves the best clinical results for the treatment of ULF.

Conservative approach for a patient with extreme delay in maxillary lateral incisor development.

The purpose of this article is to report the orthodontic treatment of a patient with extremely delayed development of the maxillary lateral incisors. At 7 years of age, the boy's permanent maxillary lateral incisors had not erupted. A radiograph showed no tooth germs in place, although well-defined radiolucent areas were evident. Removal of the radiolucent areas was contemplated, but it was rejected in favor of a conservative approach. At age 13, peg-shaped maxillary lateral incisors erupted; they were positioned during orthodontic treatment and reshaped with composite restorations, providing good esthetics and function.

Comparative study of upper lip frenectomy with the CO2 laser versus the Er, Cr:YSGG laser.

OBJECTIVES: To compare upper lip frenulum reinsertion, bleeding, surgical time and surgical wound healing in frenectomies performed with the CO2 laser versus the Er, Cr:YSGG laser. STUDY DESIGN: A prospective study was carried out on 50 randomized pediatric patients who underwent rhomboidal resection of the upper lip frenulum with either the CO2 laser or the Er,Cr:YSGG laser. Twenty-five patients were assigned to each laser system. All patients were examined at 7, 14, 21 days and 4 months after the operation in order to assess the surgical wound healing. RESULTS: Insertion of the frenulum, which was preoperatively located between the upper central incisors, migrated to the mucogingival junction as a result of using both laser systems in all patients. Only two patients required a single dose of 650 mg of paracetamol, one of either study group. CO2 laser registered improved intraoperative bleeding control results and shorter surgical times. On the other hand, the Er,Cr:YSGG laser achieved faster healing. CONCLUSIONS: Upper lip laser frenectomy is a simple technique that results in minimum or no postoperative swelling or pain, and which involves upper lip frenulum reinsertion at the mucogingival junction. The CO2 laser offers a bloodless field and shorter surgical times compared with the Er,Cr:YSGG laser. On the other hand, the Er,Cr:YSGG laser achieved faster wound healing.

Tongue and lip frenectomy in Spanish medical texts of the 16th-18th centuries.

The frena of the tongue and lip are normal structures of the buccal cavity, and surgical resection is only necessary in cases of hypertrophy. This article looks at medical texts of the Early Modern Era to analyze the origins and quality of our knowledge on this topic and examine any therapeutic measures proposed. This review shows that while the indications for carrying out tongue frenectomy are very similar to those today (speech and breastfeeding difficulties), those for carrying out a lip frenectomy are very different. Interestingly, apart from purely surgical or medicinal treatments, some authors indicated the need to complement such treatment with educational intervention and what can only be called basic speech therapy.

Association between superior labial frenum and maxillary midline diastema - a systematic review.

BACKGROUND: Pediatric otolaryngologists have seen an increased focus on upper lip frenum as a possible culprit for feeding difficulties and the development of maxillary midline diastema (MMD). This increase may be encouraged by parents' exposure to medical advice over the internet about breastfeeding and potential long-term aesthetic concerns for their children. Subsequently, there has been increased pressure on pediatric otolaryngologists to perform superior labial frenectomies. There has been a reported 10-fold increase in frenectomies since the year 2000. However, there is no consensus within the literature regarding the benefit of superior labial frenectomy in preventing midline diastema. OBJECTIVE: To provide physicians and parents with the most updated information by systematically reviewing the available literature for the association between superior labial frenum and midline diastema. METHODS: A literature search was performed in MEDLINE (PubMed), EMBASE, Web of Science, the Cochrane Library and Dental and Oral Sciences Source (DOSS). Using the Covidence platform, a systematic review was conducted. The initial 314 articles identified underwent systematic review and 11 studies were included in the final review. RESULTS/DISCUSSION: Available data, primarily from the dental literature, showed that two subtypes of frenum: papillary and papillary penetrating frenum, are associated with maxillary midline diastema. Superior labial frenectomy should be delayed until permanent lateral incisors have erupted, as this can spontaneously close the physiological MMD. Current literature recommends against frenectomy before addressing the diastema with orthodontics, which helps to prevent diastema relapse. It is also imperative to rule out other odontogenic and oral cavity causes of diastema, such as thumb sucking, dental agenesis, and other causes. Online information may not always be fully representative and should be interpreted in the full context of the patient's medical history before referral for surgical intervention.
