  Abstract 


OBJECTIVE: The objective of this study was to analyze a series of patients with facial space infection associated with comorbidities.
MATERIALS AND METHODS: Data were collated from 98 patients with facial and deep neck space infections who met the inclusion criteria over a period of 3 years. Data included demographic information, anatomic space involved, and comorbid factors.
RESULTS: A total of 98 patients who met the inclusion criteria were investigated in this study. Majority of the patients were within the age group of 46–55 (36.73%) years, whereas the least affected age group was 16–25 years (3.06%). Females were more involved while the spaces involved with Ludwig angina had the highest frequency. Diabetes mellitus (DM) was the highest comorbid factor. The patients presented mostly within 24–48 h from the onset of infection.
CONCLUSIONS: Facial and deep neck space infections occur due to spread of infection within the spaces. DM and HIV infections are the most common comorbid factors.

Keywords: Comorbid, diabetes mellitus, facial space infection, Ludwig angina

  Introduction Top


Facial spaces in the face and neck are potential spaces between the layers of fascia, normally filled with loose connective tissue and various anatomical structures such as veins, arteries, glands, and lymph nodes.[1],[2]

The anatomy of these areas includes multiple potential spaces with connecting pathways down to the mediastinum and along the entire vertebral spine.[3] Infection can spread easily from one potential space to another and also to connecting regions.[4] If facial space infections are left untreated, it can spread and involve more than one spaces and sometimes develop into life-threatening infections leading to death.[5]

Infections of facial and deep neck space are challenging due to various clinical manifestations which can present as a minimal form of inflammatory response to potentially lethal complications such as upper airway obstruction, mediastinitis, thrombosis of the internal jugular vein, septic shock, and death.[6],[7]

Ludwig angina, for example, is a potentially fatal, rapidly expanding, and progressive infection of bilateral submandibular, sublingual, and submental facial spaces.[8] Spread of infection in these spaces is facilitated by synergism between aerobic and anaerobic organisms.[9] Life-threatening complications are associated with Ludwig angina and other space infections with eventual death usually as a result of long-standing or significant sepsis.[10]

Predisposing factors such as alcoholism, immunosuppression, uncontrolled diabetes mellitus (DM), and multiple underlying medical conditions have been reported to increase the risk of infections.[11] DM is well documented as a cause of compromised immunity, poor wound healing, and increased risk of both infection and prolonged hospital stay due to increased severity of infection.[12] Furthermore, HIV infection has been reported to result in complications and long hospital stay as well as death.[12]

Our interest in the subject arose after we observed an increase in the number of fascial space infections associated with comorbid factors in relation to the spaces involved at the Maxillofacial Unit of the University of Uyo Teaching Hospital (UUTH), Uyo. The purpose of the study, therefore, is to analyze the cases seen and to use our results, identify the common risk patients, and understand the clinical characteristics of patients, especially those with comorbidities and immunosuppression such as DM and HIV infections.


  Materials and Methods Top


This study was a prospective study conducted between 2012 and 2015 on patients seen in the Oral and Maxillofacial Surgery Unit of UUTH with facial and deep neck space infections which included infections of the fascial spaces of the face and neck, cellulitis, lymphadenitis, and abscess. It was a study of 98 cases of fascial space infections comprising Ludwig's angina, parapharyngeal abscess, parotid abscess, and retropharyngeal abscess that presented in the department. Ninety-eight patients who fulfilled inclusion criteria were eventually analyzed. The following data were recorded: age, gender, comorbidities including DM and HIV were also noted as well as occupation of the patient and time of presentation.

Inclusion criteria were all facial and deep neck space infections resulting from infections as primary cause, whereas exclusion criteria were space infections from trauma. Each patient had one comorbid condition. Those with more than one comorbid conditions were excluded so as to be able to compare the effect of the comorbid factor. All cases underwent a detailed history, clinical examination, relevant investigations, and medical and surgical treatments.

Demographic information was elicited from patients using a structured questionnaire. An abscess was confirmed through a combination of the following clinical features: a well-circumscribed warm, tender swelling, fluctuant with a shiny overlying skin or erythematous mucous membrane, and pus aspirate. Cellulitis was confirmed as a warm, hard, tender, and diffuse swelling with serosanguinous aspirate of pus.

Ethical approval was obtained from the Ethical Committee of the hospital, and informed consent was obtained from the patients.

Specimen collection

After taking detailed history, each patient was thoroughly examined. Pus was collected from the infection site before commencement of antibiotic therapy. The extraoral sites were prepared with alcohol and intraoral sites were prepared with chlorhexidine. Disposable syringes (5 ml) with disposable needle of 18 gauges were used to aspirate the pus from the abscess. The aspirated syringes with needle were immediately taken to the Department of Microbiology of UUTH for the analysis.

Data analyses

Data analysis was by simple descriptive analysis.


  Results Top


A total of 98 patients who met the inclusion criteria were investigated in this study. Majority of the patients were within the age group of 46–55 (36.73%) years, whereas the least affected age group was 16–25 years (3.06%) as shown in [Table 1]. [Table 2] shows that males were more involved, whereas [Table 3] shows the spaces involved with the group having a full complement of Ludwig angina being the highest frequency with 26 (26.53%). Of the recorded comorbid factors, DM was the highest with 32 (32.65%) as shown in [Table 4]. The patients presented mostly within 24–48 h from the onset of infection [Table 5]. [Figure 1] shows soft tissue inflammation of the neck. [Figure 2] and [Figure 3] shows the clinical pictures of patients with buccal space and submental space infections respectively. [Table 6] indicates that combination of antibiotics and drainage was mostly adopted in the management of the patients. As shown in [Table 7], the highest frequency of first line antimicrobials used was penicillin, with gentamicin the least.

  Discussion Top


In this study, the patients' age ranged from 16 years to 75 years with a mean of 45 years which is similar to previous reports[13],[14] although some other studies recorded higher values.[15],[16] This age group also presents with increased rates of comorbid disease, either newly diagnosed or advanced disease. The reason for this may be due to poor checkup history due to time constraints. In the present study, male-to-female ratio was 1:2, which is in contrast to those of previous studies where more males were found to be more affected with a ratio of 2:1.[17] A possible explanation for this is that males present less for medical attention because of time constraints.[18]

Isolated submandibular space infection was the most common space affected, in agreement with a previous study.[19] This is in contrast to a study which reported that the medial masticator space was the most commonly involved facial space.[19] Ludwig angina which is a combination of submandibular, submental, and sublingual spaces and reported to have 7.8% of all facial space infections in other parts of Nigeria was lower than what was recorded in this study.[16] The three most involved spaces in descending order of frequency were submandibular, parotid, and sublingual in sharp contrast to other studies where submandibular,[20],[21] buccal, and submasseteric spaces[19] were reported to be the most frequently affected. The predominance of submandibular space infections is attributed to the higher incidence of carious mandibular molars.

HIV serostatus influenced specific fascial space involvement. Isolated submandibular, submental spaces were specific for DM, whereas Ludwig and parotid spaces were specific for HIV and DM. This is in agreement with a previous study by Srivanitchapoom et al.[22] who reported that the submandibular space was the most frequently involved in non-HIV-infected patients, whereas the superficial masticator space was the most frequently affected in HIV-infected counterparts.

Multiple fascial space involvement has been noted to be significantly associated with life-threatening comorbid factors in agreement with a previous study.[21] The role of comorbidity in the etiology and prognosis of facial infection is well documented.[16],[23] DM, HIV, and anemia were the most common comorbid factors recorded. On the contrary, Fomete et al. reported that anemia (nutritional) was the single most common comorbidity recorded, followed by DM in a study in Northern Nigeria.[24]

DM leads to compromised immunity, poor wound healing, and increased risk of both infection and prolonged hospital stay due to increased severity of infection.[12] The study by Miller and Dodson stated that diabetic patients were more at risk of developing bacteremias, pneumonia, and necrotizing fasciitis.[12],[25] There is a need for close monitoring of these patients with strict control of their blood glucose levels and early aggressive management of the initial infection or subsequent complications as stated by Chen et al.[25]

None of the 26 (26.53%) patients with HIV died of complications. This is in contrast to a previous study where 4 of the 7 seen (57.14%) died due to complications.[4] This may be due to prompt commencement of antibiotics and antiretroviral drugs. These findings are in contrast with the findings by Carey and Dodson,[26] where HIV patients had complicated and longer hospital stay and had a greater percentage of complications and death associated with the infection.

The patients presented mainly within 24–48 h in agreement with a previous study.[25] However, this is in contrast with another study with a mean period of presentation being 11.0 ± 9.4 days which was much higher than the result from this study. Due to early presentation, the majority of the patients did not have airway complications. The reason for early presentation could be due to educational level and awareness of the patients. This is a report in contrast with that of Botha et al. who reported compromised airway at presentation in majority of the patients due to late presentation.[18]

Most patients in this study had a secondary primary level of education which agrees with previous studies in Turkey[27] and India.[28] Patients of low educational status may not be exposed to knowledge of how and when to present themselves to the hospital for early intervention.

Combination of surgical drainage and use of antibiotic was the major treatment option carried out in the management of these space infections. This is also the most common line of management by other authors.[29]

In our findings, penicillin was the drug of choice for the first line of treatment cloxacillin, which is the most effective second line of antibiotics for these bacteria. This is similar to other reports in the literature.[30]

The limitation of the study was getting the patients to consent for the study, especially HIV-positive patients.
