Caldwell-Luc operation without inferior meatal antrostomy: a retrospective study of 50 cases

PURPOSE

In the standard Caldwell-Luc operation, an inferior meatal antrostomy is performed to promote sinus drainage. However, inferior meatal antrostomy has been criticized for its additional operation time and wound, early loss of the opening, and risk of injury to the nasolacrimal duct. This study retrospectively reviewed the results of the Caldwell-Luc operation without inferior meatal antrostomy in the treatment of odontogenic maxillary sinusitis or odontogenic sinus disease.

PATIENTS AND METHODS

The records of 50 patients who had an odontogenic sinus disease and underwent the Caldwell-Luc operation without inferior meatal antrostomy were reviewed. The data included the patient's age, gender, surgical indications, surgical condition, and complications.

RESULTS

From April 2004 to October 2010, there were 27 male patients and 23 female patients aged 14 to 70 years (mean, 37 years) who underwent the modified Caldwell-Luc operation. The surgical indications included intrasinus odontogenic cysts (44%), oroantral fistulae with chronic sinusitis (44%), odontoma (4%), odontogenic sinusitis (4%), and foreign bodies in the maxillary sinus (4%). The patients were successfully treated with minimal complications.

CONCLUSIONS

The modified Caldwell-Luc operation provides easier postoperative care and involves fewer complications. It is not necessary to create the inferior meatal antrostomy in the Caldwell-Luc operation when treating odontogenic sinus disease.

Functional endoscopic sinus surgery as an adjunctive treatment for closure of oroantral fistulae: a retrospective analysis

OBJECTIVE

The objective of this study was to report results of functional endoscopic sinus surgery (FESS) for treatment of chronic maxillary sinusitis of dental origin in a series of patients with oroantral fistulae (OAF).

STUDY DESIGN

Fourteen patients were treated by FESS and OAF closure by local flap. Data on severity of symptoms, diagnostic endoscopy, and coronal CT scan findings, as well as intraoperative course and complications, were recorded. The follow-up period lasted up to 2 years, comprising clinical examinations and control CT scans.

RESULTS

All OAF healed uneventfully. All patients reported improvement in severity of sinusitis symptoms, which was confirmed through results of clinical examinations and control CT scans. No significant complications were recorded. No revision surgery was needed in any case.

CONCLUSION

These results indicate that FESS, combined with OAF closure by buccal flap, might be an effective and safe option for treatment of selected cases of chronic odontogenic sinusitis with OAF.

Clinicopathological profile and surgical results of nonhealing sinuses and fistulous tracts of the head and neck region

PURPOSE

The sinus and fistulous tracts in the head and neck region often pose a challenge to the surgeon, and are usually misdiagnosed, resulting in treatment failure.

MATERIALS AND METHODS

This study included 117 patients who presented to the Department of Dental and Maxillofacial Surgery, Department of General Surgery, and Department of Dermatology of the Sheri-Kashmir Institute of Medical Sciences Medical College (Srinagar, India) over a period of 7 years. All 117 patients were analyzed using clinical methods, radiologic studies, and laboratory investigations.

RESULTS

The mean age of patients was 30 years, with a male-to-female ratio of 3:2. A dental origin was noticed in 55% of these tracts, followed by tracts originating from infected implants or bone grafts (20%) and chronic osteomyelitis (11%). Eighty percent of these tracts had a mandibular origin (and from the anterior part) (53%). Maxillary tracts arose mostly from the posterior part of the bone (70%). The commonest presenting symptom was discharge from a nonhealing wound. Anterior mandibular tracts were straight and short (84%), whereas posterior mandibular tracts were mostly long and curved (75%). Misdiagnosed and mismanaged sinuses and fistulas were mostly of odontogenic origin (70%). Radiologic studies were the most useful diagnostic tools in tracts related to dental pathology, infected implants/bone grafts, and chronic osteomyelitis. Proper treatment of basic pathology was followed by complete healing in 96% of patients.

CONCLUSION

All patients with sinus or fistulous tracts in the head and neck region should be properly assessed and evaluated for proper diagnosis and treatment, to prevent the recurrence and chronicity of these lesions.

Intraorbital abscess: a rare complication after maxillary molar extraction

BACKGROUND

The orbit is prone to being affected by an odontogenous infection, owing to its anatomical proximity to the maxillary sinus. A possible reason for an ophthalmic manifestation of a dental abscess is extraction of an acutely inflamed tooth.

CASE DESCRIPTION

The authors describe the treatment of a man who had painful swelling and redness in the area of his right eye after having a maxillary molar extracted a few days previous. A general dentist referred the patient to the clinic after he began to experience a progressive deterioration of vision of his right eye. Emergency surgical intervention prevented impending loss of vision, and subsequent healing was uneventful.

CLINICAL IMPLICATIONS

To avoid serious complications, clinicians should not perform a tooth extraction when the patient is in the acute stage of a maxillary sinus infection. Appropriate diagnostic imaging and profound evaluation of the clinical state play major roles in managing the treatment of patients with inflammatory processes that involve the oral and paraoral regions.

Treatment of oroantral fistula:experience with 27 cases

PURPOSE

To review patients with chronic oroantral and oronasal fistula who underwent surgical correction.

MATERIAL AND METHODS

Twenty-seven patients with chronic oroantral and oral fistula who underwent surgical correction in the Hacettepe University Faculty of Medicine Department of Otorhinolaryngology Head and Neck Surgery between 1968 and 2001 were reviewed retrospectively.

RESULTS

Local mucosal flaps were used for surgical correction. The underlying factors were tooth extraction in 13 patients (48%), tumor in 5 (18.5%), osteomyelitis in 3 (11%), Caldwell-Luc procedure in 2 (7.5%), trauma in 2 (7.5%), dentiginous cyst in 1(3.7%), and correction of septal perforation in 1 (3.7%). Among the fistulas, 23 were oroantral, 3 were oroantronasal, and 1 was oronasal, respectively. Two patients required revisional repairment. The surgical procedure failed in 1 diabetic patient and 3 patients with prior history of external radiotherapy.

CONCLUSION

Tooth extraction was the most common etiologic factor, and malignancy should be excluded in all patients. The outcome may not be satisfactory in patients with systemic disease and in patients with history of radiotherapy. Multiple surgical interventions may be necessary only on rare occasions.

Nonsurgical treatment for odontogenic maxillary sinusitis using irrigation through the root canal: preliminary case report

As a new nonsurgical treatment for odontogenic maxillary sinusitis (OMS), irrigation of the maxillary sinus through the root canal of the causal tooth was carried out to the patient with OMS that had proved refractory to conservative treatments (i.e., root-canal treatment of the causal tooth and antibiotic therapy). Clinical signs, symptoms, and radiographs before and after the new treatment revealed evidence of good healing. The clinical signs and symptoms, such as oppressive pain in the cheek and retrorhinorrhoea, entirely disappeared immediately after the irrigation (which was done only once) without pain, and the obstructed ostiomeatal unit was aerated on the follow-up CT images. There was no side effect associated with saline irrigation, nor any recurrence of symptoms since the irrigation. We therefore propose the irrigation through the root canal of the causal tooth as a new treatment for periapical disease-induced maxillary sinusitis, a technique that should ensure proper ventilation and drainage by relieving obstruction of the ostiomeatal unit.
