Waiting for self-healing as a primary management strategy for lower lip mucoceles.

OBJECTIVES: Oral mucoceles are most frequently encountered on the lower lip. A variety of treatment options are currently employed, including surgical excision, pharmacological injections, and laser therapy. However, each of these approaches may introduce risks and potential complications. Clinical practice has demonstrated a potential for self-healing in lower lip mucoceles, making a conservative observational approach more appealing. This research is a prospective study aimed at evaluating the self-healing capacity of lower lip mucoceles. METHODS: In this prospective study, patients with mucoceles were encouraged to intentionally delay medical intervention and to wait for self-healing. Disappearance of the mucocele for at least 3 months was defined as self-healing. RESULTS: Thirty patients with lower lip mucoceles were included. With no intervention, 24 patients (80%) reported self-healing of lower lip mucoceles. The mean natural duration of the mucoceles was 3.63 (± 4.7; 1-24) months. After self-healing of the mucocele, the patients were followed up for 17.21 (± 9.45; 2-30) months and there were no reported recurrences. CONCLUSIONS: Lower lip mucoceles have a high potential for self-healing and patients may be routinely encouraged to wait for self-healing. CLINICAL RELEVANCE: The high self-healing rate observed in this study suggests that a conservative, non-interventional approach might be considered as the first-line management for lower lip mucoceles.

Cross Lip Vermilion Flap and Traumatic Upper Lip Avulsion: Reducing Donor Site Morbidity.

Using a cross lip vermilion flap for upper red lip reconstruction in cases other than whistle deformity in patients with cleft lip can lead to donor site morbidity. If the practitioner performs primary closure of the mucosa in lower vermilion after flap harvesting, the width and height of lower lip are reduced, which results in an increased lower incisor tooth show. Using free fat grafting is an effective method for reducing donor site morbidity in the lower lip following cross lip vermilion flap harvest.

Congenital midline upper lip sinus in an infant.

Congenital lip sinus is a rare entity with upper lip sinus being rarer than the lower lip sinus. It can be an isolated entity or associated with cleft lip, palate or Van der Woude syndrome. Syndromic association requires proper evaluation and aggressive surgical treatment. Preoperative delineation of the sinus tract with ultrasound sonography or MRI is mandatory. Simple excision is sufficient in cases of isolated sinuses. In this article, we report an infant with upper lip sinus managed successfully with simple excision and reviewed the literature.

Reconstruction of Macrocheilia on the Lower Lip Through Bilateral Limited Excision and a Stepwise Single-Stage Approach (BLESS).

BACKGROUND: The surgical management of macrocheilia secondary to port-wine stains is complicated. OBJECTIVE: This study aimed to propose an innovative method for treating macrocheilia on the lower lip. METHODS: Patients who underwent the reconstruction of macrocheilia on the lower lip through the innovative approach were examined. Their preoperative and postoperative standard photographs were taken to evaluate the changes in lip length and thickness. The scores on Vancouver scar scale (VSS) and visual analog scale (VAS) were evaluated. RESULTS: Thirty-two patients who underwent the reconstruction of macrocheilia were examined. A follow-up of 12.2 months (6-36 months) was conducted. The lower lip contour and the mentolabial groove were reconstructed to normal appearance. The lip length was shortened from 5.38 ± 0.49 cm pretreatment to 4.59 ± 0.30 cm posttreatment (p = .016). The exposed vermilion was shortened from 2.05 ± 0.48 cm to 1.26 ± 0.12 cm posttreatment (p < .01). The mean VSS and VAS scores were 2.2 ± 1.5 and 8.4 ± 1.3, respectively. CONCLUSION: The bilateral limited excision and stepwise single-stage approach were safe and effective for reconstructing prominent macrocheilia on the lower lip. The technique was also easy to command for the beginners.

Complete enucleation surgical treatment and histological analysis of a mucocele in lower lip in a child: case report / Tratamiento quirúrgico de enucleación completa y análisis histológico de un mucocele en el labio inferior en un niño: reporte de caso

Objective: The aim of this case report is to describe the surgical removal of a mucocele and its histological analysis, in a child. Case Report: An 11-year-old female patient attended the Pediatric Dentistry clinic complaining of a lower lip lesion. During the anamnesis, the mother reported that the child had a habit of biting and sucking the spot frequently. Clinical examination showed the lesion was compatible with a mucocele. The proposed treatment was a complete enucleation of the lesion under local anesthesia. The incision and tissue divulsion were performed for maximum preservation of the mucosa, avoiding a possible recurrence. Total adjacent glands removal was also performed. The lesion was placed in 10% formaldehyde for histopathological analysis (H&E Staining), which showed dense connective tissue presenting chronic inflammatory infiltrate and extravasated mucin, presence of granulation tissue delimiting the area of extravasated mucin and presence of minor salivary glands. The patient was advised to quit the habit, and after seven days the sutures were removed. At the one-year follow-up there was no recurrence of the lesion. Conclusion: The proposed treatment proved to be effective without recurrence of the lesion.

Se aconsejó al paciente que abandonara el hábito, y después de siete días se retiraron las suturas. En el seguimiento de un año no hubo recurrencia de la lesión. Conclusión: El tratamiento propuesto demostró ser efectivo sin recurrencia de la lesión.

A case of minor salivary gland sialolithiasis of the upper lip.

BACKGROUND: Sialolithiasis is the most common disease of the salivary glands. Sialolithiasis usually develops in the major salivary glands, and rarely in the minor salivary glands, with only 2% of all cases of sialolithiasis occurring in the minor salivary glands and sublingual glands. Sialoliths in the minor salivary glands result in few or no clinical symptoms and are seldom identified on imaging. CASE PRESENTATION: We report herein our experience with a case of minor salivary gland sialolithiasis in a 67-year-old woman. On examination, an elastic soft, mobile, and well-circumscribed mass was palpable within the left upper lip. Ultrasound examination revealed a hypoechoic mass with heterogeneous internal echoes. The mass was excised under local anesthesia. Based on histopathological findings, a diagnosis of minor salivary gland sialolithiasis was established. CONCLUSIONS: Diagnosis of minor salivary gland sialolithiasis is challenging due to the difficulty of detecting sialoliths on imaging. A well-circumscribed mass was detected in the upper lip, and ultrasound examination revealed a round lesion, raising the suspicion of a benign tumor. Other diseases that can develop at the upper lip are calcified lymph node, phlebolith, fibroma, pleomorphic adenoma, myxoma, vascular malformation, salivary gland tumor, non-specific sialadenitis, and malignant tumor. Surgical excision is the favored approach for confirming a diagnosis of intramucosal nodular lesions.

New technical method to correct secondary vermilion deformities with cleft lip.

Various techniques for correcting whistling deformities that occurred after primary surgery for cleft lip have been reported. These techniques are mainly intended to correct the lack of volume of the red lip. However, irregularity of the dry-wet lip junction (mucocutaneous junction) in the red lip has rarely been mentioned. If the wet lip is located in an exposed area, not only is the aesthetic appearance poor but also uncomfortable complications such as a crusted or bleeding lip repeatedly occur under a dry condition. A new technique for correcting the irregular line of the dry-wet lip junction is described in this report. The technique is simple. After removal of the exposed wet lip, flaps are designed on both dry lip sides of the defect as M-W-M plasty and are transposed toward the defect. The dog-ears are small; the scar is inconspicuous because it is incorporated with the wrinkle line, and scar contracture is prevented. In addition, more soft tissues may be included to correct a mild whistling deformity.

Surgical excision and mucosal advancement flap: Treatment for refractory lichen planus of the lip.

Lichen planus of the lip (LPL) is not common, and only a few cases have been reported. Medical treatment modalities for LPL are not always effective. Therefore, treatment of this presentation is difficult and challenging. A 41-year-old man was referred to the dermatology clinic with a chronic, painful erosion on the lower lip and buccal mucosa. Treatment with topical steroids, systemic cyclosporine, dapsone, and systemic steroids failed. We performed surgical excision and mucosal advancement flap treatment, with complete response noted after 6 months. Surgical excision with mucosal advancement flap treatment may be effective for the treatment of refractory LPL.

Somatic GNAQ mutation in different structures of port-wine macrocheilia.

BACKGROUND: Port-wine macrocheilia (PWM) involves a congenital, progressive capillary malformation that results in soft-tissue hypertrophy in the lips. Its aetiology has not yet been fully elucidated. OBJECTIVES: To investigate frequencies of GNAQ mutation in different tissues from patients with PWM, including skin, mucosa, gland and muscle, using samples obtained during cheiloplasty. METHODS: Targeted next-generation sequencing of GNAQ was designed and performed to assess DNA extracted from 80 different affected tissues from 20 patients with PWM. RESULTS: The GNAQ R183Q mutation was not detected in gland samples but was found in 90%, 95% and 95% of the skin, mucosal and muscle samples, respectively. The lowest levels of mutations were found in the glands (P < 0·001 vs. skin, mucosa and muscle), and levels were second lowest in the skin (P = 0·023 vs. mucosa; P = 0·012 vs. muscle). The mutation frequencies in mucosa and muscle were the highest and showed no statistically significant difference (P = 0·92). CONCLUSIONS: In patients with PWM, GNAQ was mutated in all tissues except for glands. PWM is congenital, and all tissue layers exhibit primary hypertrophy rather than acquired or partially related hypertrophy. Given the advantages of mucosal biopsy, including practicality, lack of scarring and rapid healing, GNAQ mutation in the lip mucosa may be a useful predictor for early-stage PWM in patients with port-wine stains affecting the lips.

Labial Incompetence in Mobius Syndrome: LeFort I Impaction Case Report and Review of Management Strategies.

Difficulty with speech intelligibility in Mobius syndrome patients due to bilabial incompetence is common yet rarely discussed. We present a patient with Mobius syndrome who underwent counterclockwise LeFort I impaction to improve her labial competence. In addition, we present a literature review of management strategies for labial incompetence correction in Mobius patients. At 7-year follow-up after LeFort 1 impaction, the patient reports improvement in speech intelligibility, specifically regarding the ability to pronounce bilabial consonants. This is the first published report of LeFort I impaction to improve labial competence and bilabial consonant pronunciation in a Mobius syndrome patient.

Congenital Midline Upper Lip Sinuses: 3 Rare Cases.

Congenital sinuses of the upper lip are rare congenital malformations. There have been only 40 cases described in the literature. We report 3 cases of congenital midline upper lip sinus in Caucasian children. Two of those lesions were associated with other anomalies (complete cleft palate and hemifacial macrosomia or submucous cleft palate with bifid uvula). The pathophysiology remains unexplained yet. Congenital upper lip sinuses can be considered as possible microforms of cleft-lips. Associated anomalies are frequent and must be sought. The treatment is a full excision of the sinus tract and of the skin around the punctum in order to avoid risks of recurrence.
