Acute presentation of an intraoral dermoid cyst causing airway compromise in a young child

Sublingual Dermoid Cyst in Young Child

A dermoid cyst is a benign congenital lesion of ectodermal origin that can arise in any region of the body, though occurrence is rare. A young girl aged 2 years 4 months was referred to our hospital because of a painless mass in the floor of the mouth. Intraoral examination findings revealed a painless movable elastic soft mass on the floor of the mouth measuring approximately 15 mm in diameter. Magnetic resonance imaging indicated a cystic lesion, with low signal intensity shown in T1-weighted and extremely high signal intensity in T2-weighted images. These clinical findings indicated the presence of a dermoid cyst and removal was planned. Under general anesthesia with nasal intubation, surgical removal was performed through an incision on the floor of the mouth. Blunt dissection exposed the integrity of the cyst capsule, which was weakly attached to adjacent tissue. The excised mass was 19 mm × 14 mm × 11 mm in size. Histological examination findings confirmed a diagnosis of dermoid cyst. The operation was successfully completed without any complications and the postoperative course was good. It is important to properly evaluate cysts in children and provide proper treatment with appropriate timing.

Diagnosis and management of congenital floor of mouth masses: A systematic review

OBJECTIVES

Determine the utility of preoperative imaging and the optimal course of management for congenital floor of mouth (FOM) cysts in infants.

METHODS

A systematic review of the literature was performed conforming to PRISMA guidelines. Pubmed, Embase and Cochrane Library databases were queried to identify cases of infants with congenital floor of mouth masses. Patient demographics, presenting findings, imaging, management, complications, and outcomes were determined.

RESULTS

85 patients were evaluated. 98% of patients presented at 16 months of age or younger. The most common presenting symptom was submental mass or swelling, 31.3%. Among the patients that underwent imaging, the suspected diagnosis obtained from imaging findings was consistent with the final pathologic diagnosis 59% of the time reported and inaccurate 34% of the time. There were multiple definitive treatment modalities described in the literature review including surgical excision, 82.3%, marsupialization, 12.9%, chemical injection 2.3%, sclerotherapy 1.2%,% and radiation, 1.2%. Recurrence rate after initial definitive treatment was as follows, surgical excision, 8.8%, marsupialization, 80%, sclerotherapy, 100%, chemical injection, 50%, and radiation, 100%.

CONCLUSION

Preoperative imaging studies should not be relied upon alone to determine suspected pathology and subsequent management in pediatric patients with FOM masses. It may be beneficial for these patients to undergo primary surgical excision regardless of imaging studies or suspected pathology. Needle aspiration offers limited addition to pathologic diagnosis and should only be performed in the setting of acute symptomatic management. Surgical excision should be considered as definitive treatment modality in all patients with FOM masses, regardless of the suspected diagnosis of ranula. Further multi-institutional cohort studies could be invaluable to elucidate definitive treatment guidelines in this patient population.

Major complications after tongue-tie release: A case report and systematic review

INTRODUCTION

The diagnosis of ankyloglossia, or tongue-tie, and the number of frenotomies performed has increased over 10-fold from 1997 to 2012 in the United States. The sharpest increase has been in neonates. For parents considering frenotomy for their breastfeeding newborn, there is controversy surrounding the evaluation of tongue-tie and the benefit of a frenotomy. Complications from tongue-tie procedures are thought to be low, though it is not well reported nor studied.

OBJECTIVES

The aim of this study is to describe a case of a sublingual mucocele after laser frenotomy in a neonate with tongue-tie and to investigate major complications reported after tongue-tie release in pediatric patients through a systematic review of the literature.

CASE REPORT

We present a 6-week-old female who underwent a laser frenotomy procedure performed by a dentist who presented with a new cyst under her tongue.

MATERIAL AND METHODS

A systematic literature search of articles published from 1965 to April 2020 was conducted in Ovid MEDLINE(R), Ovid EMBASE, and Scopus. Citations were uploaded into a systematic review software program (DistillerSR, Ottawa, ON, Canada), followed by full text screening.

RESULTS

47 major complications were reported in 34 patients, including our patient. Most of the cases were located in the United States and Europe. The most frequent indications for the procedure were breastfeeding problems (n = 18) and speech impediment (n = 4). The procedure was performed by dentists (n = 6), lactation consultants (n = 5), and otolaryngologists (n = 4). The bulk of the major complications after frenotomy included poor feeding (n = 7), hypovolemic shock (n = 4), apnea (n = 4), acute airway obstruction (n = 4), and Ludwig angina (n = 2).

CONCLUSIONS

Reporting of complications after frenotomy is lacking. Risks to neonates may be different than risks to older children and adults. Practitioners across different specialties should be monitoring and studying this more rigorously to better guide patients and families on the risks and benefits of this procedure.

Diagnosis System for Swallowing and Peristalsis Function for Artificial Tongue and Esophagus Development

With the progress of surgical technology, the survival rate after resection of esophageal and tongue carcinomas has improved. However, the surgical protocol for esophageal and tongue surgery is complex, and surgery for elderly esophageal and tongue carcinoma patients with cardiopulmonary dysfunction is difficult. Using an artificial tongue and esophagus will be helpful for patients. However, peristalsis of foods depends on food size, taste, and viscosity. This study developed and evaluated a new diagnosis machine for drinking and peristalsis motion. Before clinical evaluation, animal experiments were performed on healthy adult goats using a stereo camera. After a feasibility study of the diagnosis system for peristalsis, clinical evaluation was conducted on healthy normal volunteers. We observed no aspiration pneumonia. The foods and drinks tested were safe. There was no mis-swallowing, but the participants' feeling with regard to taste differed. Overall, the results indicated that the quantitative swallowing and peristalsis diagnosis system is safe. Evaluation of the visual imaging and spectral analysis gave us useful information about peristalsis, which will help us design an artificial tongue and esophagus with a good control mechanism in the near future.

Sublingual dermoid cyst in an infant: A case report and review of the literature

Dermoid cysts usually occur later in the second decade of life; we present the approach of an unusual case of an infant who presented a cyst within the oral cavity, which is important because it can be confused with other pathologies.
