The clinical importance of marsupialization treatment of the cystic lesion of the jaws: Analysis of the dental pulp vitality

Decompression-first or direct enucleation: The choice of treatment for medium-sized odontogenic jaw cysts

BACKGROUND

The treatment of medium-sized odontogenic jaw cysts is inconsistent at present. Two main treatments, namely decompression and enucleation, are used overlappingly. This retrospective analysis aims to provide useful references for technique selection for future management of medium-sized odontogenic jaw cysts.

METHODS

Odontogenic cysts with lesion sizes ranging 2-4 cm were included. The clinical and radiological data of the patients were reviewed. Decompression-first and direct enucleation treatments were the two main surgical techniques. The preoperative parameters and postoperative outcomes were compared between the two groups.

RESULTS

Out of 69 patients included, 40 (58 %) were in the decompression group and 29 (42 %) in direct enucleation group. The logistic regression analysis of preoperative parameters demonstrated that the maximum lesion size and the chief surgeon's preference could affect the selection of surgical techniques for medium-sized cysts (P < 0.05). Receiver operating characteristic curve analyses demonstrated that a lesion size >2.5 cm was the best cutoff value for predicting a decompression selection. Most postoperative outcomes differed significantly between the two groups (P < 0.05). Lower-risk anesthesia, shorter hospitalization, tooth function protection, and fewer neurosensory impairments were decompression-favoring outcomes. However, more follow-up visits, more postoperative X-rays, and longer postoperative care were outcomes against decompression. The recurrence rate was low and did not differ significantly between the two groups (P > 0.05).

CONCLUSIONS

There is no apparent preference for treating medium-sized jaw cysts. The maximum lesion size is a moderate-impact factor for treatment selection. A tendency to prefer decompression-first with larger lesion size was found in medium-sized jaw cysts. The advantages of teeth preservation and low neurosensory impairment of decompression were verified in the medium-size jaw cysts. The burden of postoperative care should be considered when selecting decompression.

Conservative management of multiple odontogenic keratocysts in a child with nevoid basal cell carcinoma syndrome: A case report

BACKGROUND

Nevoid basal cell carcinoma syndrome (NBCCS) is an autosomal dominant multisystemic disorder characterized by the presence of multiple odontogenic keratocysts (OKC), which are a hallmark feature of the syndrome. The treatment of these OKC poses challenges due to their high recurrence rates and the myriad of management options available.

CASE REPORT

We describe here a case of NBCCS diagnosed in an 11-year-old girl who presented with multiple OKC in the jaws. Chest and cranial radiographs showed no abnormalities in the ribs and the cerebral falx, respectively. Cephalometric analysis indicated mandibular retrusion, a skeletal class II relationship, and a convex profile. The treatment approach involved a personalized strategy tailored for each cyst, comprising marsupialization followed by enucleation. This approach aimed to minimize surgical trauma and to reduce the risk of recurrence. The patient underwent regular follow-up appointments, demonstrating successful outcomes with no signs of recurrence or de novo OKC observed over a 32-month period.

CONCLUSION

Clinicians should consider lesion characteristics and patient cooperation when determining treatment strategies for the optimization of outcomes for children and adolescents with NBCCS and multiple OKC.

A 3-year follow-up clinical study on the preservation for vitality of involved tooth in jaw cysts through an innovative method

Jaw cysts commonly affect the oral and maxillofacial region, involving adjacent tooth roots. The management of these teeth, particularly regarding root canal therapy and apicoectomy, lacks consensus. This study introduces a novel treatment concept and refined surgical approach to preserve pulp viability in teeth involved in jaw cysts. The objective was to investigate the effectiveness and potential benefits of this approach over a 36-month follow-up period. A conservative management approach prioritized vitality preservation, reserving root canal treatment and apicectomy for cases with post-operative discomfort. A comprehensive follow-up of 108 involved teeth from 36 jaw cyst cases treated with the modified method was conducted. Clinical observation, X-ray imaging, cone-beam computed tomography (CBCT), and pulp vitality testing assessed changes in cyst size, tooth color, pulp vitality, root structure, and surrounding alveolar bone. After 36 months, our modified surgical approach successfully preserved tooth vitality in 84 involved teeth. Adverse symptoms in 19 teeth, such as redness, swelling, fistula, and pain, resolved with postoperative root canal therapy. Follow-up was lost for five teeth in two cases. No cyst recurrences were observed, and in 34 cases, the bone cavity gradually disappeared, restoring normal bone density during long-term follow-up. Our modified surgical method effectively preserves tooth vitality in jaw cysts. This innovative approach has the potential to improve the management of teeth involved in jaw cysts.
